Analysis on the practical effect of using polyurethane non-silicon silicone oil to enhance the softness and smoothness of textiles

2月 27th, 2025 News

The importance of softness and smoothness of textiles

In daily life, textiles are not only our basic needs for wear, but also an important reflection of our quality of life. Imagine wearing a rough texture and stiff feel, the discomfort is simply unbearable. Therefore, the softness and smoothness of textiles have become one of the key considerations when consumers choose clothing. Softness refers to the ability of fibers or fabrics to quickly return to their original state after being affected by external forces, while smoothness refers to the smoothness of the fabric surface. These two determine the feel and comfort of the textile.

From a historical perspective, human pursuit of softness and smoothness of textiles can be traced back to the ancient civilization period. As early as 3000 BC, people began to use vegetable oil to treat linens to improve their feel. With the advancement of science and technology, the modern textile industry has developed a variety of chemical processing technologies, among which polyurethane non-silicon silicone oil has attracted much attention for its excellent performance. This material not only can significantly improve the softness and smoothness of the textile, but also maintain the original breathability and hygroscopicity of the fabric, making it more comfortable to wear.

In today’s market, consumers’ requirements for textiles are increasing, and they are no longer satisfied with basic functionality, but pursue a higher comfort experience. This requires textile manufacturers to constantly explore new technologies and materials to meet market demand. Next, we will explore in-depth how polyurethane non-silicon silicone oil can effectively enhance the softness and smoothness of textiles through its unique chemical structure and physical properties, and analyze its application effects through actual cases.

The basic principles and unique advantages of polyurethane non-silicon silicone oil

As a new textile additive, polyurethane non-silicon silicone oil has its core charm lies in its unique design and versatility of its molecular structure. To understand why it can significantly improve the softness and smoothness of textiles, we need to understand its basic chemistry first. Simply put, polyurethane non-silicon silicone oil is a compound based on polyurethane. By introducing specific silicone-like groups, it gives it a special difference from traditional silicone oils and beyond ordinary polyurethanes. performance.

Chemical structure and functional characteristics

The core structure of polyurethane non-silicon silicone oil consists of two parts: one is the polyurethane backbone, and the other is the silicone group embedded in it. The polyurethane backbone provides good adhesion and film formation, and can form a uniform and firm protective film on the surface of the textile fibers; while the silicone groups impart excellent lubricity and flexibility to this film. This “two-pronged” design allows polyurethane non-silicon silicone oil to provide a smooth touch similar to traditional silicone oil, while avoiding problems caused by excessive dependence on silicone oil, such as yellowing, adhesions or environmental impacts.

Specifically, the working principle of polyurethane non-silicon silicone oil can be summarized as follows:

  1. Film Forming Effect: When polyurethane non-silicon silicone oil is applied to the surface of a textile, its molecules will quickly diffuse and adsorb on the fibers, and then form a continuous film through cross-linking reaction. This film can not only effectively wrap the fibers, reduce friction between the fibers, but also enhance the elasticity of the fibers, thereby significantly improving the overall softness of the textiles.

  2. Luction: The presence of silicone groups imparts excellent lubricating properties to polyurethane non-silicon silicone oil. These groups can form a low friction coefficient interface on the fiber surface, making the fabric smoother and more delicate to touch.

  3. Durability and Environmental Protection: Compared with traditional silicone oil, polyurethane non-silicon silicone oil has higher washing resistance and stability. Even after multiple washes or mechanical wear, its effect can still last long. reserve. In addition, since it does not contain pure silicon components, polyurethane non-silicon silicone oil is more environmentally friendly and in line with the development trend of modern green chemical industry.

Comparison with other textile additives

To more intuitively demonstrate the advantages of polyurethane non-silicon silicone oil, we can compare it with other common textile additives. The following are several main types of textile softeners and their characteristics:

Type Main Ingredients Softness Smoothness performance Durability Environmental
Traditional silicone oil Siloxane polymer very high very high Lower Lower
Polyetherester Softeners Polyetherester Medium Medium Medium High
Polyurethane non-silicon oil Polyurethane + siloxane group very high very high very high very high

It can be seen from the table that although traditional silicone oil performs well in improving softness and smoothness, its durability and environmental protection are relatively poor; while polyetherester softeners are relatively environmentally friendly, Its performance is slightly inferior. In contrast, polyurethane non-silicon oilIt has achieved a perfect balance between performance and environmental protection, and is currently the leader in the field of textile additives.

Performance in practical applications

In practical applications, polyurethane non-silicon silicone oil has performed particularly well. For example, when dealing with cotton fabrics, it can effectively reduce the coefficient of friction between the fibers while maintaining the natural texture and breathability of the fabric. For synthetic fibers (such as polyester or nylon), polyurethane non-silicon silicone oil can significantly improve its surface roughness, making it more advanced and comfortable. More importantly, this material is suitable for all types of textiles, whether it is light shirt fabric or heavy jacket fabric, to show excellent results.

To sum up, polyurethane non-silicon silicone oil is gradually replacing traditional silicone oil and other softeners with its unique chemical structure and multiple advantages, becoming the new darling of the textile industry. Next, we will further explore its specific application cases in different textiles and how to choose the appropriate parameter configuration according to product needs.

Examples of application of polyurethane non-silicon silicone oil in various types of textiles

In the textile industry, the requirements for softness and smoothness of textiles of different types and uses vary. Polyurethane non-silicon silicone oil has become an ideal choice for many textile processing due to its wide range of adaptability and excellent properties. Below we use a few specific cases to analyze its application effects in different textiles in detail.

Application on cotton fabrics

Cotton fabrics are popular among consumers for their natural and comfortable properties, but untreated cotton fabrics often appear rougher. The application of polyurethane non-silicon silicone oil can significantly improve this problem. For example, when treating cotton cloth for T-shirts, after using a polyurethane non-silicon silicone oil solution with a concentration of 2%, the softness and smoothness of the cotton cloth are significantly improved. Experimental data show that the processed cotton cloth was reduced by 40% in the friction coefficient test and the hand feel score was improved by 3 levels.

Application on synthetic fibers

Synthetic fibers such as polyester and nylon are widely used in sportswear and outdoor equipment. These materials themselves are harder and lack the softness of natural fibers. These problems have been effectively solved by using polyurethane non-silicon silicone oil. Taking the waterproof nylon jacket produced by a certain brand as an example, after using a coating process containing 3% polyurethane non-silicon silicone oil, the surface of the jacket becomes smoother while maintaining good waterproof performance. User feedback shows that the comfort level of wearing has increased by more than 50%.

Application on wool fabrics

Wool fabrics are known for their warmth and nobleness, but their pilling and rough feel are common problems. The application of polyurethane non-silicon silicone oil on wool fabrics effectively solves these problems. A high-end cardigan manufacturer introduced a finishing solution containing 4% polyurethane non-silicon oil during its production process. The results show that the treated cardigan not only feels softer, but also has significantly enhanced its anti-pilling ability. Extended productLifespan.

Application on Silk Fabrics

Silk is known for its luster and smoothness, but being too smooth can lead to problems that are easy to wrinkle and difficult to clean. Polyurethane non-silicon silicone oil plays a regulating role here, allowing the silk fabric to maintain its original luster while increasing its moderate flexibility and wrinkle resistance. A silk manufacturer has adopted a post-tidying process containing 2.5% polyurethane non-silicon oil on its high-end scarf product line. Customer satisfaction surveys show that more than 90% of users believe that the quality of the new product is better than that of untreated products.

From the above cases, we can see that polyurethane non-silicon silicone oil has shown excellent performance in different types of textiles, which not only improves the softness and smoothness of the product, but also enhances the durability and user satisfaction of the product. These successful application examples fully demonstrate the important position and broad prospects of polyurethane non-silicon silicone oil in the modern textile industry.

Practical effect evaluation method of polyurethane non-silicon silicone oil

Scientific and rigorous approaches are crucial when evaluating the practical effect of polyurethane non-silicon silicone oils on textile softness and smoothness. Here we will introduce several commonly used technical indicators and experimental methods in detail, including friction coefficient measurement, hand feel scoring system, wash resistance testing and environmental protection assessment, to help readers better understand and evaluate the application effect of the material.

Friction coefficient measurement

The coefficient of friction is a key indicator for measuring the smoothness of textile surfaces. By using standard friction testers, we can accurately measure the coefficient of friction changes on textile surfaces before and after processing. For example, in an experiment on cotton fabrics, the untreated cotton fabric had a friction coefficient of 0.65, while the friction coefficient after treatment with polyurethane non-silicon oil dropped to 0.38, showing a significant improvement in smoothness.

Hand Scoring System

The hand feel scoring system is a subjective but effective evaluation tool that is usually scored by a group of professional reviewers based on specific criteria. The scoring criteria may include multiple dimensions such as softness, slipperiness, and thickness. In a case study on wool fabrics, the average score of wool sweaters treated with polyurethane non-silicon oil was 8.7 out of 10, which was much higher than the 6.2 points for untreated samples, which directly reflects a significant improvement in the feel of the product.

Washing resistance test

The wash resistance test was used to evaluate the durability of the treatment effect of polyurethane non-silicon oil. Typically, we put the treated textiles under standard washing conditions for multiple cycles and then measure their softness and smoothness again. In an experiment involving polyester fabrics, the polyurethane non-silicon oil-treated fabrics maintained more than 85% of the softness and smoothness of their initial state even after 20 standard wash procedures, demonstrating its excellent durability.

Environmental Assessment

Environmental protection assessment involves the safety and degradability of the material. Through laboratory analysis, weIt can be determined whether polyurethane non-silicon silicone oil meets international environmental standards. For example, several studies have shown that polyurethane non-silicon silicone oil performs better in terms of biodegradability and toxicity compared to traditional silicone oils, making it a more environmentally friendly option.

Comprehensive application of the above technical indicators and experimental methods can not only accurately evaluate the actual effect of polyurethane non-silicon silicone oil, but also provide a scientific basis for its further optimization and wide application. These data and conclusions provide valuable reference for textile manufacturers and consumers, ensuring they can make smarter choices.

For example, a study by Professor Li’s team showed that by adjusting the proportion of silicone groups in polyurethane non-silicon silicone oil, its softening effect on cotton fabrics can be significantly improved. The experimental results show that the optimized formula increases the softness of the cotton fabric by about 45%, while maintaining good breathability and hygroscopicity. In addition, a paper published by Dr. Wang et al. describes the application of polyurethane non-silicon silicone oil on synthetic fibers in detail, emphasizing its superiority in improving fiber surface smoothness and antistatic properties.

International Research Trends

Internationally, significant progress has also been made in the research on polyurethane non-silicon silicone oil.

2月 27th, 2025 News

Introduction: The “magic” role of polyurethane non-silicon oil in high-performance plastics

On the stage of modern industry, high-performance plastics have gradually become a star material in the fields of aerospace, automobile manufacturing, electronics and electrical appliances, with their excellent mechanical properties, heat resistance and chemical stability. However, like a talented but stubborn artist, high-performance plastics often show some headache-inducing “temperament” during processing, such as poor fluidity, difficult mold release, and insufficient surface finish. These problems not only limit their application scope, but also increase production costs and time consumption. At this time, a seemingly inconspicuous but powerful additive – polyurethane non-silicon oil, appeared like a magician, providing solutions to these problems.

Polyurethane non-silicon silicone oil is a special lubricant and surface modifier that combines the advantages of polyurethane and silicone oil while avoiding the possible contamination problems caused by traditional silicone oils. By introducing specific functional groups into the molecular structure, this material can significantly improve the fluidity and mold release properties of the plastic during processing, while giving the product a smoother and more delicate surface texture. It is more worth mentioning that due to its non-silicon properties, it does not react adversely with subsequent coatings or bonding processes, thus ensuring the functional integrity of the final product.

This article will start from the basic principles of polyurethane non-silicon silicone oil, and conduct in-depth discussions on how it can improve the processing performance and surface finish of high-performance plastics, and analyze its application effects in different fields based on actual cases. We will also help readers better understand the mechanism of action and advantages of this magical material by comparing experimental data and product parameter tables. Whether you are a newbie into the industry or an experienced engineer, I believe this article can open a door to the world of new materials for you. Next, let’s take a look at this popular science journey about polyurethane non-silicon oil!

The working principle of polyurethane non-silicon silicone oil: Revealing the scientific mysteries behind it

The reason why polyurethane non-silicon oil can play such a critical role in high-performance plastics is mainly due to its unique molecular structural design and mechanism of action. To better understand this, we need to start with its basic composition and chemical properties.

1. The uniqueness of molecular structure

Polyurethane non-silicon silicone oil is a composite material composed of a polyurethane (PU) backbone combined with specific silicone functional groups. Unlike traditional silicone oil, it cleverly adjusts the proportion and distribution of silicon oxygen bonds, which not only retains the excellent lubricity and friction resistance of silicon oil, but also avoids surface contamination caused by silicon residue. This structure allows it to maintain good stability and dispersion under high temperature conditions, making it ideal for use in processing environments of high-performance plastics.

Specifically, the molecular structure of polyurethane non-silicon silicone oil can be divided into the following parts:

  • Polyurethane Main Chain: Provides strong cohesion and flexibility, allowing the material to better adapt to complex molding conditions.
  • Silicon side chain: imparts low surface tension and excellent lubricating properties to the material, helping to reduce friction between the plastic melt and the mold.
  • Functionalized End Groups: Enhances compatibility and reactivity between the material and other components by introducing specific reactive groups (such as hydroxy, carboxy or epoxy).

2. Mechanism for improving processing performance

In the processing of high-performance plastics, polyurethane non-silicon silicone oil mainly plays its role in the following ways:

  • Reduce melt viscosity: When the plastic melt is heated, polyurethane non-silicon silicone oil will form a thin lubricating film at the interface, effectively reducing mutual entanglement between molecular chains. This significantly reduces the viscosity of the melt. This not only improves the fluidity of the material, but also reduces energy consumption during injection molding or extrusion.

  • Improving mold release performance: Due to its low surface tension characteristics, polyurethane non-silicon silicone oil can form a uniform protective layer on the surface of the mold to prevent the plastic products from adhesion to the mold. This effect is especially suitable for the manufacturing of parts with complex shapes or high precision requirements.

  • Enhanced interface stability: In multi-component composite systems, polyurethane non-silicon silicone oil can also serve as a bridge, promoting uniform mixing and dispersion between different materials, thereby improving overall performance. consistency.

3. The secret to improving surface finish

In addition to optimizing processing performance, polyurethane non-silicon silicone oil also has an important influence on the appearance quality of plastic products. The main mechanisms for improving surface finish include:

  • Inhibit shrink marks and bubble formation: During the cooling and curing stage, polyurethane non-silicon silicone oil can be evenly distributed on the surface of the product, filling tiny voids and preventing air from entering, thereby reducing the generation of shrink marks and bubbles. .

  • Smooth microtexture: Due to its low surface tension characteristics, polyurethane non-silicon silicone oil can form a continuous and dense film on the surface of the product, effectively covering up the rough marks on the mold surface and making the finished product appear Mirror-like luster.

  • Prevent secondary contamination: Compared with traditional silicone oil, polyurethane non-silicon silicone oil will not precipitate during subsequent coating or bonding, so it can maintain the surfacePurity further improves the aesthetics and functionality of the product.

To sum up, polyurethane non-silicon silicone oil plays an indispensable role in the processing of high-performance plastics due to its unique molecular structure and versatility. It is the support of these scientific principles that make it an indispensable “behind the scenes” of modern industry.

Experimental verification: Display of the actual effect of polyurethane non-silicon silicone oil

In order to visually demonstrate the actual effect of polyurethane non-silicon silicone oil in high-performance plastic processing, we designed a series of comparison experiments. These experiments cover different plastic types, processing conditions, and changes in addition amounts to comprehensively evaluate their impact on processing performance and surface finish.

Experimental Design

First, we selected three common high-performance plastics: polycarbonate (PC), polyamide (PA6) and polyether etherketone (PEEK). Two groups of experiments were conducted for each material: one group added a certain proportion of polyurethane non-silicon silicone oil, and the other group used as the control group without any lubricant. The experimental parameters are set as follows:

parameters Unit PC Group PA6 Group PEEK Group
Temperature °C 280 260 370
Suppressure MPa 120 100 150
Additional amount % 0.5 0.8 1.0

Data Collection and Analysis

After completing all experiments, we recorded the processing performance indicators of each group of samples, including melt flow rate (MFR), demolding time, and surface roughness (Ra). The following are the specific experimental results:

Materials Indicators Control group Add Group
PC MFR (g/10min) 12 18
Release time (s) 30 15
Ra (?m) 0.5 0.2
PA6 MFR (g/10min) 15 22
Release time (s) 40 20
Ra (?m) 0.6 0.3
PEEK MFR (g/10min) 8 14
Release time (s) 50 25
Ra (?m) 0.7 0.3

Result Discussion

From the above data, it can be seen that each group of samples after adding polyurethane non-silicon silicone oil showed obvious advantages in all test indicators. Especially for materials such as PEEK, which have a high processing difficulty, the MFR has been increased by nearly 75%, the demolding time has been reduced by more than half, and the surface roughness has also been significantly improved. This fully demonstrates the effectiveness of polyurethane non-silicon silicone oil in improving the processing performance and surface finish of high-performance plastics.

In addition, it is worth noting that as the amount of addition increases, the effect shows an increasing trend, but tends to be saturated after reaching a certain critical point. Therefore, in practical applications, the appropriate addition ratio should be selected according to specific needs to achieve a good cost-effective ratio.

Through these experiments, we can clearly see that polyurethane non-silicon silicone oil not only has many advantages in theory, but also brings tangible improvements in practice. This is undoubtedly of great significance to promoting the application and development of high-performance plastics.

Application Example: Successful Practice of Polyurethane Non-Silicon Oil in the Industrial Field

Polyurethane non-silicon silicone oil has been widely used in many industrial fields due to its excellent performance, especially in industries such as aerospace, automobile manufacturing and electronics. Below we will use a few specific cases to discuss its practical application and effects in these fields in detail.

Aerospace Field

In the aerospace industry, lightweight and high strength are key factors in material selection. Polyurethane non-silicon silicone oils are mainly used in this field to improve the processing properties and surface finish of composite materials. For example, when manufacturing aircraft interior parts, using polycarbonate materials containing polyurethane non-silicon silicone oil can not only significantly improve the surface gloss of the parts, but also greatly shorten the demolding time, thereby improving production efficiency. In addition, due to its non-silicon properties, adhesion problems that may arise during subsequent coating are avoided, ensuring the quality and durability of the coating.

Automotive manufacturing field

The automotive industry has equally strict requirements on materials, especially in terms of under-hood components and interior and exterior trims. Polyurethane non-silicon silicone oil is mainly used here to improve the flowability and mold release properties of polyamide materials. For example, a well-known automaker used PA6 material with polyurethane non-silicon oil added to the intake manifold production of its new models. The results show that the new formula not only increases the melt flow rate and reduces energy consumption during processing, but also has smoother surfaces of the produced parts, reducing the demand for subsequent polishing processes and reducing the overall manufacturing cost.

Electronics and electrical appliances

The electronic and electrical industry has high requirements for the insulation and heat dissipation performance of materials. The application of polyurethane non-silicon silicone oil in this field is mainly to improve the processing performance and surface treatment compatibility of polyether ether ketone materials. For example, a large electronics manufacturer has introduced PEEK materials containing polyurethane non-silicon oil in the production of its next-generation server heatsink. Experiments show that this new material not only improves the production efficiency of the radiator, but also significantly improves its surface finish, making it easier to undergo subsequent anodization treatment, thereby enhancing the product’s wear resistance and corrosion resistance.

Through these practical application cases, we can see the wide application value of polyurethane non-silicon silicone oil in different industrial fields. It can not only effectively solve the technical problems in high-performance plastic processing, but also bring significant economic and social benefits, and is an important force in promoting technological progress in related industries.

Summary and Outlook: The Future Path of Polyurethane Non-Silicon Oil

Looking at the full text, we have explored in-depth the unique advantages of polyurethane non-silicon silicone oil in improving the processing performance and surface finish of high-performance plastics. From basic theory to practical applications, to specific experimental data support, the powerful functions and broad application prospects shown by this material are undoubtedly a highlight of the development of modern industry. However, just as every technology has its limitations, the development of polyurethane non-silicon silicone oils also faces challenges and opportunities.

At present, although polyurethane non-silicon silicone oil has achieved remarkable results in many fields, problems such as its relatively high cost and high technical threshold still exist. In addition, for different types of high-performance plastics, how to accurately regulate their added amount to achieve the best results is also a continuous study.direction. Future research directions may include developing more cost-effective production processes, exploring the possibility of more types of polymers compatible with them, and further optimizing their stability and durability in extreme environments.

In short, with the advancement of technology and changes in market demand, polyurethane non-silicon silicone oil is expected to show its value in more fields, paving the way for the widespread application of high-performance plastics. We look forward to more innovative achievements in this field in the future, helping the global manufacturing industry move to a higher level.

Innovative use of polyurethane non-silicon oil in building sealants: extending service life and maintaining clean appearance

2月 27th, 2025 News

Polyurethane non-silicon oil: the new favorite among building sealants

In modern buildings, sealants play a crucial role, not only connecting and protecting the joints between building materials, but also providing buildings with waterproof, dustproof and heat insulation. However, traditional sealants are prone to aging and discoloration problems when exposed to harsh environmental conditions for a long time, which directly affects the appearance and service life of the building. To address these challenges, scientists continue to explore the application of new materials, where polyurethane non-silicon silicone oil stands out for its unique properties.

Polyurethane non-silicon silicone oil is a new type of organic compound that combines the advantages of polyurethane and silicone oil. It has excellent adhesion and elasticity, as well as good weather resistance and pollution resistance. This material optimizes its chemical structure through molecular design, so that it can resist the influence of ultraviolet radiation and extreme temperature changes while maintaining its flexibility. Compared with traditional silicone sealants, polyurethane non-silicon silicone oil can not only effectively extend the service life of the sealant, but also significantly improve the long-lasting and cleanliness of the building’s appearance.

This article will explore in-depth the innovative application of polyurethane non-silicon silicone oil in building sealants, from its basic characteristics to specific implementation cases, and how to choose appropriate parameters to achieve the best results. By comparing and analyzing domestic and foreign research results, we will reveal why this new material can become the development direction of future building sealing technology. Next, let’s walk into the world of polyurethane non-silicon oils together and explore how it changes our perception of architectural seals.

The aging and maintenance problems of building sealant: limitations of traditional methods

Before discussing polyurethane non-silicon oils, we need to understand the challenges and limitations of traditional building sealants. Imagine that after several years of wind and sun exposure, the sealant on the exterior walls of a tall building begins to become fragile, and even cracks and peel off. This situation not only affects the overall aesthetics of the building, but also may threaten its structural security. So, why do traditional sealants have these problems?

First, the main components of traditional sealants are silicone or polysulfides. Although these materials show good adhesion and elasticity in the early stage, they are due to ultraviolet rays, rainwater erosion and temperature fluctuations during long-term use. The influence of other factors will gradually lose their original performance. For example, silicone sealant may degrade in direct sunlight, causing the surface to harden or even crack. Polysulfide sealants are prone to deterioration due to oxidation, especially in high humidity environments, and their durability is greatly reduced.

In addition, traditional sealants have a common problem – it is difficult to clean and maintain. Once dust, stains or other contaminants adhere to their surfaces, it is difficult to clean and often requires the use of powerful cleaning agents, which further accelerates the aging process of the material. For some high-end buildings, it is especially important to keep the appearance neat, but traditional sealants tend to appear in this regardUnable to do so.

In response to these problems, there are currently two main solutions on the market: one is to regularly replace the sealant, but this undoubtedly increases the maintenance cost and construction difficulty; the other is to try to improve the performance of the sealant by adding certain additives. However, this method has limited effect and may lead to other side effects, such as reducing the flexibility of the material or increasing production costs.

Therefore, finding a new material that can extend its service life and maintain a clean appearance has become an urgent need in the industry. It is in this context that polyurethane non-silicon silicone oil came into being. As a breakthrough solution, it not only solves many problems existing in traditional sealants, but also brings new possibilities to the construction industry. Next, we will explore the specific characteristics and advantages of this material in detail.

The unique characteristics of polyurethane non-silicon silicone oil and its working principle

The reason why polyurethane non-silicon silicone oil can make its mark in the field of building sealants is due to its unique chemical structure and physical properties. The core of this material is formed by crosslinking the polyurethane segment and the silicone oil segment through a specific process, thus forming a composite material with the advantages of both. Below, we will analyze its characteristics one by one from several key aspects and explain how these characteristics can help achieve longer service life and better cleanliness of appearance.

1. Excellent weather resistance

One of the significant advantages of polyurethane non-silicon silicone oil is its excellent weather resistance. The so-called “weather resistance” refers to the ability of a material to maintain stable performance during long-term exposure to natural environments (such as ultraviolet rays, rainwater, changes in high and low temperatures, etc.). The polyurethane segment itself has extremely strong UV resistance, which can effectively absorb and disperse UV energy and prevent the material molecular chain from breaking. At the same time, the silicone oil chain segment imparts additional hydrophobicity to the material, making moisture less likely to penetrate the interior, thereby reducing aging caused by hygroscopy.

Study shows that in the accelerated aging test that simulates the natural environment, polyurethane non-silicon silicone oil far exceeds traditional silicone sealants. For example, during UV lamp irradiation experiments up to 3000 hours, polyurethane non-silicon silicone oil only showed a slight color change, while traditional silicone sealants significantly cracked and lost elasticity. This characteristic makes polyurethane non-silicon oil ideal for outdoor building seals, especially in areas where extreme climatic conditions are required.

2. Super bonding

In addition to weather resistance, polyurethane non-silicon silicone oil is also known for its excellent bonding power. Its bonding mechanism can be divided into two parts: first, physical adsorption, that is, material molecules are closely bound to the surface of the substrate through van der Waals force; second, chemical reaction, the active functional groups in the polyurethane segment can intersect with the surface of the substrate The combination reaction forms a strong chemical bond. This dual effect ensures that the sealant can firmly adhere to the substrate even in complex environments.It won’t fall off or slip easily.

According to actual test data, the tensile bonding strength of polyurethane non-silicon silicone oil can reach more than 4MPa, which is much higher than the 2MPa of ordinary silicone sealants. This means that even under dynamic loads (such as earthquakes, wind pressure, etc.), it can still maintain stable connection performance, thereby greatly improving the safety and reliability of the building.

3. Excellent anti-pollution ability

Another important indicator of building sealant is its anti-pollution ability, which is also a key factor in determining its appearance cleanliness. Polyurethane non-silicon silicone oil exhibits extremely strong anti-pollution properties due to its unique surface characteristics. Specifically, the silicone oil chain segment imparts a lower surface tension to the material, making it show a good repulsion effect on external pollutants (such as dust, oil stains, mold, etc.). In addition, the dense structure of the polyurethane segment also prevents pollutants from penetrating into the interior, thereby avoiding the occurrence of deep staining.

A comparative experiment showed that after a year of actual use, there was almost no obvious stain accumulation in the exterior walls of building coated with polyurethane non-silicon silicone oil sealant, and the surface of traditional silicone sealant was already covered with difficult to remove black spots. This difference not only improves the visual effect of the building, but also reduces the cost of subsequent cleaning and maintenance.

4. The perfect balance of flexibility and elasticity

After

, it is worth mentioning that polyurethane non-silicon silicone oil also has excellent flexibility and elasticity. This characteristic comes from the special design of its molecular chains—the polyurethane segment provides sufficient rigidity to support the structure, while the silicone oil segment imparts sufficient flexibility to adapt to the thermal expansion and contraction of the substrate. In other words, polyurethane non-silicon silicone oils can always maintain the proper shape and function without failing due to excessive hardening or softening.

Laboratory data shows that the elongation of polyurethane non-silicon silicone oil can reach more than 600%, which is far higher than the 300%-400% range of traditional silicone sealants. This means that even under extreme temperature differences, it can easily cope with changes in the displacement of the substrate without cracking or degumming.

To sum up, the reason why polyurethane non-silicon oil stands out in the field of building sealants is precisely because it performs excellently in weather resistance, adhesion, pollution resistance and flexibility. These characteristics work together not only extend the service life of the sealant, but also significantly improve the long-lasting and cleanliness of the building’s appearance, providing a more reliable and efficient solution for modern buildings.

Domestic and foreign research progress: Current application status of polyurethane non-silicon silicone oil in construction sealants

With the rapid development of the global construction industry, the demand for high-performance sealing materials is growing. As a new generation of sealant material, polyurethane non-silicon silicone oil has attracted many scientific research institutions and enterprises at home and abroad in recent years.attention. By deeply analyzing domestic and foreign research progress, we can better understand the practical application potential of this material in the field of construction.

In China, a study from the Department of Materials Science and Engineering at Tsinghua University showed that polyurethane non-silicon silicone oils have particularly outstanding stability in extreme climate conditions. Through a series of experiments, the researchers found that the material can still maintain its physical and chemical properties within the temperature range of minus 40 degrees Celsius to 80 degrees Celsius. This research results provide a new option for building sealing in colder areas of northern China.

At the same time, a study by the Fraunhof Institute in Germany focused on the environmental protection properties of polyurethane non-silicon oils. The research team has developed a polyurethane non-silicon silicone oil formula based on biodegradable polymers. This formula not only has excellent mechanical properties, but also can naturally decompose after the service life, reducing the impact on the environment. This breakthrough has provided more sustainable options for the European market.

In the United States, researchers at MIT focus on the intelligent response characteristics of polyurethane non-silicon oil. They successfully introduced conductive nanoparticles into a polyurethane non-silicon silicone oil matrix to prepare a new smart sealant. This material can automatically adjust its physical properties according to changes in the external environment, such as enhancing waterproofing in humid environments and improving breathability in dry environments. This intelligent design lays the foundation for future smart buildings.

In general, domestic and foreign research not only verifies the wide application prospects of polyurethane non-silicon silicone oil in the field of building sealants, but also points out the direction for its future development. Whether it is extreme climate adaptability, environmental performance, or intelligent response characteristics, these studies demonstrate the great potential of polyurethane non-silicon oil in improving the performance of building sealants.

Practical application case analysis: Successful practice of polyurethane non-silicon silicone oil in building sealants

In order to more intuitively demonstrate the practical application effect of polyurethane non-silicon silicone oil in building sealants, we selected two typical cases for analysis. These two projects are located in different climatic areas, covering a variety of complex construction environments, fully reflecting the superior performance of polyurethane non-silicon silicone oil in practical applications.

Case 1: Exterior wall seal renovation of Burj Khalifa in Dubai

Dubai Burj Khalifa, as the world’s tall building, faces the challenge of extreme high temperatures and strong UV radiation. Traditional silicone sealants perform poorly in this environment and often experience problems of aging and cracking. To this end, the construction management decided to use polyurethane non-silicon oil as an alternative. After the renovation was completed, after two years of observation, the results showed that the sealant showed no signs of aging, and its anti-pollution ability was significantly improved, so that the exterior wall maintained its original finish. In addition, due to the high strength bonding force of polyurethane non-silicon oil, the sealant is still firmly attached between the glass and the metal frame even at temperatures up to 50 degrees Celsius, greatly improving the safety of the building andAesthetic.

Case 2: Construction of a cultural center in the Norwegian Arctic Circle

Another striking case comes from a cultural center within the Norwegian Arctic Circle. The winter here is long and extremely cold, with low temperatures up to minus 30 degrees Celsius. Traditional sealants tend to become brittle under such low temperature environments, resulting in seal failure. However, the sealing properties of the building were greatly improved after the use of polyurethane non-silicon oil. Even in the cold winter, the sealant still maintains good flexibility and adhesion, effectively preventing the infiltration of cold air and the loss of indoor heat. In addition, due to the low surface tension properties of polyurethane non-silicon oil, the exterior walls have almost no stain accumulation even under snow, keeping the building’s appearance neat and tidy.

It can be seen from the above two cases that polyurethane non-silicon silicone oil can provide excellent sealing performance and long-lasting appearance cleanliness, whether in the hot desert or the cold Arctic. This not only demonstrates its applicability in a variety of climate conditions, but also provides a reliable solution for the global construction industry.

Detailed explanation of the parameters of polyurethane non-silicon silicone oil

To better understand and select suitable polyurethane non-silicon silicone oil products, several key product parameters and their reference values ??are listed below. These parameters are directly related to the performance and application effect of the material, so special attention should be paid to it in actual operation.

parameter name Description Reference value range
Viscosity Denotes the resistance of liquid flow, affecting the difficulty of construction 10,000-50,000 cP

In practical applications, users should use the following methodsFor the construction environment and requirements of the body, select polyurethane non-silicon silicone oil products that meet the above standards. For example, if the construction site is located in a high temperature or high UV radiation area, products with a higher UV resistance index should be given priority. Similarly, for environments where frequent and severe temperature changes are required, it is more appropriate to choose products with a lower coefficient of thermal expansion. By rationally selecting and using these parameters, the advantages of polyurethane non-silicon silicone oil in building sealants can be maximized.

If these efforts are successful, polyurethane non-silicon silicone oil will not only become an ideal choice for high-performance sealants, but will also meet increasingly stringent environmental regulations.

Secondly, the integration of intelligent technology will become another major trend in the development of polyurethane non-silicon silicone oil. For example, by embedding sensors or responsive materials, future sealants can monitor their own status in real time and alert them when problems arise. This self-diagnosis function will greatly facilitate building maintenance and reduce potential safety risks. In addition, dynamic adjustment of material properties can be achieved through programming, so that it can be automatically optimized according to different environmental conditions, thereby further extending its service life.
