The rise of environmentally friendly coatings and the emergence of polyurethane non-silicon oil
In today’s society, the improvement of environmental awareness has prompted all walks of life to seek a greener and more sustainable development path. The coatings industry is no exception, and traditional solvent-based coatings are receiving increasing attention and restrictions due to their volatile organic compounds (VOC) emissions. Against this background, environmentally friendly paints emerged and became the new darling of the market. This type of paint not only reduces the impact on the environment, but also provides a healthier living space.
Polyurethane non-silicon silicone oil is a new additive and is particularly eye-catching in environmentally friendly coatings. It is a substance synthesized through a special process, combining the advantages of polyurethane and silicone oil, but avoiding certain disadvantages that traditional silicone oil may bring. The unique feature of this material is that its molecular structure not only contains the strength and wear resistance of the polyurethane segment, but also combines the lubricity and smoothness of the silicone oil segment. Therefore, it can significantly improve the touch and durability of the coating surface without sacrificing the coating performance.
This article will explore in-depth how polyurethane non-silicon silicone oils play a role in environmentally friendly coating formulations, especially its unique contribution to enhancing the smoothness and wear resistance of coating surfaces. Through detailed scientific principles analysis, practical application case analysis and comparison with other similar products, we will fully understand the potential of this innovative material and its important position in the modern coating industry.
Chemical characteristics and mechanism of polyurethane non-silicon silicone oil
The reason why polyurethane non-silicon silicone oil can shine in environmentally friendly coatings is closely related to its unique chemical structure. This material consists of polyurethane segments and siloxane segments, and the synergistic effect of the two imparts a range of excellent properties. From a microscopic perspective, the polyurethane segment has excellent mechanical strength and flexibility, which can significantly enhance the wear resistance and scratch resistance of the coating; while the silicone segment has low surface energy and high mobility Known for providing excellent smoothness and self-cleaning effect to the coating.
1. The function of polyurethane segments: building a strong protective barrier
The polyurethane segment is one of the core components of polyurethane non-silicon silicone oil. Its molecular structure is mainly composed of alternately arranged hard and soft segments. This design makes polyurethane both rigid and elastic. The hard segment is usually composed of diisocyanate and small molecule chain extender, which imparts high strength and good thermal stability to the material; the soft segment is composed of long-chain polyols, responsible for providing flexibility and low-temperature adaptability. When this material is introduced into the coating system, the polyurethane segments form a dense crosslinking network during the curing process, thereby greatly improving the hardness and wear resistance of the coating.
Specifically, the polyurethane segment enhances coating performance in two ways:
- Improving wear resistance: Crosslinked network formed by polyurethane segmentsThe network can effectively disperse external pressure and reduce wear during friction. This means that the coating can maintain its integrity even under frequent use or high load conditions.
- Improving adhesion: The polyurethane segment can also form a firm chemical bond with the surface of the substrate, ensuring that the coating does not fall off easily and further extend its service life.
2. The function of siloxane segments: imparting a smooth surface
If the polyurethane segment is “reinforced concrete”, then the silicone segment is “lubricating oil”. The silicone segments are dominated by silicon oxygen bonds, and methyl groups or other functional groups are distributed around them. This structure gives them extremely low surface energy and excellent mobility. In coating systems, the silicone segments will preferentially migrate to the coating surface to form a dense and smooth protective film. This film not only reduces the friction coefficient, but also effectively resists the adhesion of dust and stains.
The following are the main functions of the siloxane segment:
- Enhance the slipperyness: Due to its low surface energy characteristics, the silicone segments significantly reduce the friction between the coating and external objects, making the touch smoother. This feature is particularly important for products that require frequent contact, such as furniture, flooring and automotive interiors.
- Enhanced Self-cleaning Capacity: The presence of siloxane segments can also prevent contaminants from penetrating into the interior of the coating, thereby simplifying the cleaning process and extending the coating life.
3. Synonymative effect of both: performance beyond single components
It is worth noting that the polyurethane segment and the siloxane segment are not simply superimposed, but are deeply integrated through chemical bonding or physical entanglement. This synergistic effect allows polyurethane non-silicon oil to have the advantages of both, while avoiding their respective disadvantages. For example, although traditional silicone oil has excellent slipperiness, its high temperature resistance and chemical resistance are poor; the addition of polyurethane segments makes up for this deficiency, making the overall performance of the material more balanced.
To understand the mechanism of action of polyurethane non-silicon oil more intuitively, we can compare it to a high-performance racing car. The polyurethane segment is like the chassis and engine of a racing car, providing strong power and stability; the silicone segment is a special coating on the tires, ensuring that the vehicle can drive smoothly under various road conditions. Only when these two are perfectly combined can good performance be achieved.
From the above analysis, it can be seen that polyurethane non-silicon silicone oil has successfully played an indispensable role in environmentally friendly coatings due to its unique chemical structure. Next, we will further explore its performance in practical applications and verify its excellent performance through experimental data.
Polyurethane non-silicon silicone oil in environmentally friendly coatingsApplication example
The application of polyurethane non-silicon silicone oil in environmentally friendly coatings is not limited to theoretical discussion, but its performance in practical applications is even more impressive. The following uses several specific examples to show its application effect in different fields.
Furniture Paints
In the furniture industry, the application of polyurethane non-silicon oil has greatly improved the appearance and durability of wooden furniture. Taking a well-known brand as an example, after they used environmentally friendly coatings containing polyurethane non-silicon oil on solid wood furniture, they found that the coating was not only smoother, but also improved wear resistance by more than 40%. Customer feedback shows that these furniture is easier to clean in daily use and remains bright and as new as a whole for a long time. This not only improves the market competitiveness of the product, but also increases consumer satisfaction.
Auto paint
Auto paint is another important area that benefits from polyurethane non-silicon oils. In a study on automotive exterior paint, researchers added polyurethane non-silicon silicone oil to water-based coatings. Test results showed that the coating’s scratch resistance and UV resistance were significantly improved. Especially in tests under severe weather conditions, the surface of the car coated with this new coating showed stronger weather resistance, effectively protecting the body from erosion from the natural environment.
Floor Paint
Floor coatings are also an important area where polyurethane non-silicon silicone oils show their advantages. A flooring manufacturer has used environmentally friendly coatings containing polyurethane non-silicon oil in its new product line, and the results show that the surface hardness and slippage of the new floors have reached unprecedented levels. User reports that flooring is not only easier to maintain, but also has no obvious wear marks in areas where it is used frequently, greatly extending the service life of the floor.
Through these practical applications, we can see the important role of polyurethane non-silicon silicone oil in improving the performance of environmentally friendly coatings. It not only enhances the smoothness and wear resistance of the coating, but also greatly improves the overall quality and user experience of the product.
Comparative analysis of polyurethane non-silicon silicone oil and other additives
In the coatings industry, choosing the right additive is crucial to the performance of the final product. As an emerging material, polyurethane non-silicon silicone oil has its superior performance in many aspects, especially in improving the smoothness and wear resistance of the coating. However, there are a variety of other additives available on the market, such as traditional silicone oils, fluorocarbons and other types of polyurethane modifiers. This section will compare these materials in detail to highlight the unique advantages of polyurethane non-silicon oils.
1. Comparison with traditional silicone oil
Traditional silicone oil is widely used in coatings due to its excellent smoothness and hydrophobicity. However, they have some inherent defects such as poor high temperature resistance and easy migration from the coating surface. In contrast, polyurethane non-silicon silicone oil significantly improves heat resistance and migration resistance by introducing polyurethane segments. surface1 shows the differences in key performance indicators of these two materials:
| Performance metrics | Traditional silicone oil | Polyurethane non-silicon oil |
|---|---|---|
| Smoothness | High | very high |
| Abrasion resistance | Medium | High |
| Heat resistance | Poor | very good |
| Migration | Easy to migrate | It is not easy to migrate |
It can be seen from the table that although traditional silicone oil has excellent performance in smoothness, it is much inferior in wear and heat resistance. Polyurethane non-silicon silicone oil is significantly better than traditional silicone oil in these two key properties.
2. Comparison with fluorocarbon
Fluorocarbons are known for their ultra-low surface energy and excellent chemical resistance, but their high cost and complex production processes limit their wide application. Although polyurethane non-silicon silicone oil is slightly inferior in surface energy, its comprehensive performance is more balanced and its cost is more competitive. In addition, fluorocarbons can have adverse environmental impacts in some cases, while polyurethane non-silicon oils are fully environmentally friendly.
3. Comparison with other polyurethane modifiers
Although other types of polyurethane modifiers can also improve certain properties of the coating, they often need to be used in conjunction with other additives to achieve the desired effect. Polyurethane non-silicon silicone oils usually meet most needs due to their versatility. This simplicity and efficiency make polyurethane non-silicon oil more attractive in practical applications.
To sum up, polyurethane non-silicon silicone oil not only performs excellently in key performance indicators, but also has obvious advantages in cost-effectiveness and environmental protection. These characteristics make it a potential additive in the coatings industry.
