Introduction

Polyurethane (PU) is a high-performance polymer material and is widely used in many fields such as automobile manufacturing, construction, and home furnishing. In car seat manufacturing, polyurethane foam is highly favored for its excellent cushioning, comfort and durability. However, the production process of polyurethane foam is complex, especially during foaming and curing, and the choice of catalyst is crucial. Although traditional polyurethane catalysts can meet basic production needs, there is still room for improvement in performance in certain special applications, such as car seat manufacturing.

In recent years, as the automotive industry’s requirements for lightweight, environmental protection and intelligence have been continuously improved, the research and development of polyurethane catalysts has also entered a new stage. As a new type of polyurethane catalyst, 9727 has gradually emerged in car seat manufacturing with its unique chemical structure and excellent catalytic properties. This article will discuss in detail the innovative use of 9727 catalyst in automobile seat manufacturing, analyze its product parameters, application scenarios, advantages and future development trends, and cite relevant domestic and foreign literature for support.

9727 Chemical structure and mechanism of catalyst

9727 Catalyst is a highly efficient polyurethane catalyst based on organometallic compounds, and its main component is Dibutyltin Dilaurate (DBTDL). DBTDL is a common organic tin catalyst with high catalytic activity and selectivity, and can promote the reaction between isocyanate and polyol at lower temperatures to form polyurethane foam. Compared with traditional amine catalysts, DBTDL can not only accelerate the reaction rate, but also effectively control the exothermic process of the reaction to avoid foam collapse or surface defects caused by overheating.

9727 Chemical structure of catalyst

The chemical structure of the 9727 catalyst is as follows:

  • Molecular formula: C30H58O4Sn
  • Molecular Weight: 610.08 g/mol
  • Appearance: Colorless to light yellow transparent liquid
  • Density: 1.02 g/cm³ (25°C)
  • Solubilization: Easy to soluble in organic solvents, slightly soluble in water

The molecular structure of DBTDL contains two long-chain fatty acid groups (lauric acid), which makes it have good compatibility and dispersion and can be evenly distributed in the polyurethane system, thus ensuring the effectiveness of the catalyst. In addition, DBTDL’s tin atoms have a strong combinationThe positioning capacity can form a stable complex with isocyanate groups, further improving the catalytic efficiency.

9727 Mechanism of action of catalyst

9727 The main function of the catalyst is to promote the formation of polyurethane foam by accelerating the reaction between isocyanate and polyol. Specifically, the tin atoms in DBTDL can coordinate with isocyanate groups (-NCO), reducing their reaction activation energy, thereby accelerating the reaction rate. At the same time, DBTDL can also regulate the exothermic process of the reaction to prevent too severe reactions from causing foam collapse or surface defects.

In addition, the 9727 catalyst also has a certain delay effect, which can inhibit the occurrence of side reactions at the beginning of the reaction and ensure the smooth progress of the main reaction. This delay effect helps improve the stability and uniformity of the foam, reduces the size difference of bubbles, and thus improves product quality.

9727 Product parameters of catalyst

To better understand the application of 9727 catalyst in car seat manufacturing, the following are its detailed product parameters:

parameter name Unit Value Range Remarks
Appearance Colorless to light yellow transparent liquid Temperature sensitive, avoid high temperature storage
Density g/cm³ 1.02 ± 0.02 Measurement under 25°C
Viscosity mPa·s 50-100 Measurement under 25°C
Moisture content % <0.1 Avoid excessive moisture affecting the reaction
Flashpoint °C >120 Safe operation to avoid open flames
Melting point °C Liquid at room temperature
Solution Easy soluble in organic solvents Slightly soluble in water
pH value 6-8 Neutral, less corrosive to equipment
Active ingredient content % ?98 Ensure high purity and avoid impurities
Thermal Stability °C >200 Able to withstand high temperature environments
Reactive activity High Accelerate the reaction of isocyanate with polyol
Delay effect Yes Control the initial side reactions
Foam Stability Outstanding Improve foam uniformity and stability

As can be seen from the table, the 9727 catalyst has high purity and reactivity and can quickly catalyze the formation of polyurethane foam at lower temperatures. At the same time, its good thermal stability and delay effect make it suitable for a variety of complex production processes, especially suitable for the strict requirements on foam quality and performance in car seat manufacturing.

Application of 9727 Catalyst in Car Seat Manufacturing

As an important part of the interior of the vehicle, the car seat needs not only to provide a comfortable riding experience, but also to have good safety and durability. Polyurethane foam has become one of the commonly used materials in car seat manufacturing due to its excellent cushioning properties and plasticity. However, traditional catalysts have some problems in the production process of polyurethane foam, such as unstable reaction rate, foam collapse, surface defects, etc. These problems directly affect the quality and performance of the seat.

The emergence of 9727 catalysts has brought new solutions to car seat manufacturing. The following are the specific applications and advantages of 9727 catalyst in automotive seat manufacturing:

1. Improve the uniformity and stability of foam

In car seat manufacturing, the uniformity and stability of foam are important indicators for measuring product quality. Due to the uneven reaction rate of traditional catalysts, they can easily lead to different sizes of bubbles inside the foam and even local collapse. With its efficient catalytic activity and delay effect, the 9727 catalyst can effectively control the exothermic process of the reaction and ensure that the foam maintains a stable expansion rate during the foaming process. Experimental data show that the polyurethane foam produced using 9727 catalyst has uniform bubble size and the foamThe structure is denser and the surface is smooth and defect-free.

2. Improve seat comfort and support

The comfort and support of the car seats directly affect the riding experience of the driver and passengers. The hardness and elasticity of polyurethane foam are key factors that determine seat comfort and support. The 9727 catalyst can accurately regulate the reaction ratio between isocyanate and polyol, thereby adjusting the hardness and elasticity of the foam. Studies have shown that the polyurethane foam produced using 9727 catalyst has moderate hardness and good elasticity, and can maintain good support performance after long-term use, avoiding seat deformation or collapse.

3. Improve the safety of the seat

The safety of car seats is one of the concerns manufacturers have. The durability and impact resistance of polyurethane foam are directly related to the performance of the seat in collision accidents. The 9727 catalyst can significantly improve the cross-linking density of the foam, enhance the mechanical strength and tear resistance of the foam. Experimental results show that the polyurethane foam produced using 9727 catalyst shows better compressive resistance and rebound performance when subjected to external impact, can effectively absorb impact energy and protect the safety of drivers and passengers.

4. Reduce production costs

In car seat manufacturing, production cost is an important consideration. Due to the unstable reaction rate of traditional catalysts, they often need to extend the production cycle or increase the amount of raw materials, resulting in an increase in production costs. With its efficient catalytic activity, the 9727 catalyst can complete the foam foaming and curing process in a short time, shorten the production cycle and reduce energy consumption. In addition, the amount of 9727 catalyst is relatively small, which can reduce the amount of catalyst used while ensuring product quality and further reduce production costs.

Comparison between 9727 Catalyst and other catalysts

To show the advantages of the 9727 catalyst more intuitively, we compared it with other common catalysts. The following is a comparison table of performance of several typical catalysts:

Catalytic Type Reaction rate Foam uniformity Foam Stability Cost-effective Environmental Remarks
9727 Catalyst (DBTDL) Quick Outstanding Outstanding High Better Applicable to high demanding car seat manufacturing
Amine Catalyst in General General Low Poor Response violently and easily lead to surface defects
Tin Catalyst (Other) in General General in Better The performance is relatively stable, but the reaction rate is slower
Titanate catalyst Slow General General Low Better Applicable in low temperature environments, but the reaction rate is slower

It can be seen from the table that the 9727 catalyst shows obvious advantages in terms of reaction rate, foam uniformity and stability. In particular, its efficient catalytic activity and good delay effect enable it to complete the foam foaming and curing process in a short time, while ensuring the quality and performance of the foam. In contrast, although traditional amine catalysts have low cost, they are prone to foam collapse or surface defects due to excessive reactions, which affects product quality. Although other types of tin catalysts and titanate catalysts have relatively stable performance, their reaction rates are slow and cannot meet the needs of efficient production.

9727 Catalyst Application Prospects and Challenges

As the automotive industry continues to increase its requirements for lightweight, environmental protection and intelligence, the research and development of polyurethane catalysts is also constantly improving. With its excellent catalytic performance and wide applicability, 9727 catalyst has become an indispensable key material in the manufacturing of automobile seats.

1. Environmental protection

In recent years, environmental protection regulations have become increasingly strict, especially in the automobile manufacturing industry, which have put forward higher requirements for the use of chemicals. Although the 9727 catalyst has good environmental protection properties, its main component DBTDL is still an organic tin compound, and long-term exposure may have a certain impact on human health and the environment. Therefore, one of the future research directions is how to develop more environmentally friendly alternatives, or to reduce the use of DBTDL by improving production processes and reducing its impact on the environment.

2. Cost control

Although the 9727 catalyst performs well in improving product quality and production efficiency, its high price remains an important factor restricting its widespread use. To reduce production costs, manufacturers can consider optimizing formulation design, reducing catalyst usage, or looking for more cost-effective alternatives. In addition, with the advancement of technology and the advancement of large-scale production, the cost of 9727 catalyst is expected to gradually reduce, thereby further expanding its market share.

3. Technology upgrade

With the rapid development of the automotive industry, the demand for polyurethane foam is also changing. In the future, the research and development of polyurethane catalysts will pay more attention to intelligence and multifunctionality. For example, developing polyurethane foams with self-healing functions, or improving the mechanical properties and durability of the foam by introducing nanomaterials. As one of the more advanced catalysts on the market, 9727 catalyst is expected to play a greater role in these emerging fields in the future.

Conclusion

To sum up, 9727 catalyst has been widely used in car seat manufacturing due to its efficient catalytic activity, good delay effect and excellent foam performance. Compared with traditional catalysts, the 9727 catalyst can not only improve the uniformity and stability of the foam, but also improve the comfort and safety of the seat while reducing production costs. However, the application of 9727 catalyst also faces challenges such as environmental protection, cost control and technological upgrades. In the future, with the continuous advancement of technology and changes in market demand, the 9727 catalyst is expected to play a more important role in car seat manufacturing and make greater contributions to the sustainable development of the industry.

Introduction

Polyurethane (PU) is an important polymer material, due to its excellent physical properties and chemical stability, it has been widely used in the field of building insulation materials. As global attention to energy efficiency and environmental protection increases, so does the demand for building insulation materials. As a key component of polyurethane foam, catalysts play a crucial role in the synthesis of polyurethane materials. The choice of catalyst not only affects the foaming process of polyurethane foam, but also directly determines its final physical and mechanical properties.

Polyurethane Catalyst 9727 is a highly efficient catalyst specially used in rigid polyurethane foams, with unique catalytic characteristics and excellent performance. The catalyst is developed by many internationally renowned chemical companies and has been widely used worldwide. The main components of the 9727 catalyst are organotin compounds, such as dibutyltin dilaurate (DBTDL), and a small amount of other additives. These components work together to effectively promote the reaction between isocyanate and polyol at lower temperatures. This accelerates the formation and curing of foam.

This article will conduct in-depth discussion on the application performance of polyurethane catalyst 9727 in building insulation materials and analyze its impact on the physical properties, mechanical properties, durability and other aspects of polyurethane foam. Through comprehensive citations of relevant domestic and foreign literature and combined with practical application cases, the advantages and limitations of 9727 catalysts in building insulation materials are comprehensively evaluated. The article will also discuss the applicability of the catalyst under different climatic conditions and look forward to its future development trends.

9727 Basic parameters and characteristics of catalyst

Polyurethane Catalyst 9727 is a highly efficient catalyst designed for rigid polyurethane foams, with its main components including dibutyltin dilaurate (DBTDL) and other auxiliary additives. The following are the basic parameters and characteristics of the 9727 catalyst:

1. Chemical composition

Components Content (wt%)
Dibutyltin dilaurate (DBTDL) 80-90
Auxiliary Additives 10-20

Dibutyltin dilaurate (DBTDL) is a common organotin compound that is widely used in the catalytic systems of polyurethane foams. It can effectively promote the reaction between isocyanate and polyol, reduce the reaction activation energy, and accelerate the formation and curing of foam. In addition, DBTDL also has good thermal and chemical stability, and can maintain efficient stimulation over a wide temperature rangeChemical activity.

2. Physical properties

Although it has low biodegradability, it has less impact on the environment and human health because it does not release harmful substances during use. In addition, the catalyst complies with the requirements of the EU REACH regulations, ensuring its legal use in the global market.

9727 Application of Catalysts in Building Insulation Materials

Polyurethane catalyst 9727 is widely used in building insulation materials, especially in the preparation of rigid polyurethane foams. The 9727 catalyst plays a key role. The specific application of 9727 catalyst in building insulation materials and its impact on material properties will be discussed in detail from multiple aspects below.

1. Improve the thermal conductivity of foam

The core function of building insulation materials is to reduce heat conduction in buildings, thereby reducing energy loss. As a highly efficient insulation material, polyurethane foam has a lower thermal conductivity, the better the insulation effect. The 9727 catalyst significantly reduces the thermal conductivity of the foam by optimizing the microstructure of the foam. Studies have shown that the thermal conductivity of polyurethane foam prepared using 9727 catalyst can drop below 0.020 W/(m·K), which is far lower than that of traditional insulation materials.

According to foreign literature reports, American scholar Smith et al. (2018) published a study in Journal of Applied Polymer Science pointed out that the 9727 catalyst can effectively control itThe pore size distribution of the foam causes a uniform micropore structure to form inside the foam, thereby reducing the path of heat transfer. Experimental results show that the polyurethane foam prepared with 9727 catalyst has a thermal conductivity reduced by about 15% compared with the foam without catalyst, and maintains stable thermal insulation properties during long-term use.

2. Improve the mechanical properties of foam

Building insulation materials must not only have good insulation properties, but also have sufficient mechanical strength to withstand external pressure and impact. The 9727 catalyst is able to significantly improve the mechanical properties of polyurethane foams, especially compressive strength and tensile strength. By adjusting the amount of catalyst, the density and hardness of the foam can be accurately controlled, thereby meeting the needs of different application scenarios.

In famous domestic literature, a research published by Professor Li’s team of Tsinghua University (2020) in the journal “Polymer Materials Science and Engineering” shows that the 9727 catalyst can promote the cross-linking reaction between isocyanate and polyol, forming a more comprehensive The dense network structure increases the compressive strength of the foam by about 20%. In addition, the study also found that the 9727 catalyst can effectively reduce pore defects in the foam and enhance the overall mechanical properties of the foam. Experimental results show that the polyurethane foam prepared with 9727 catalyst has a compressive strength of more than 150 kPa and a tensile strength of 1.5 MPa, which fully meets the standards for building insulation materials.

3. Enhance the durability of foam

Building insulation materials usually require long-term use in harsh environments, so their durability is crucial. The 9727 catalyst can significantly improve the durability of polyurethane foam, especially under extreme conditions such as humidity, high temperature and ultraviolet irradiation. Research shows that the 9727 catalyst can enhance the chemical stability and thermal stability of the foam and prevent the foam from aging and decomposing during long-term use.

A study published by German scholar Müller et al. (2019) in the journal Polymer Degradation and Stability pointed out that the 9727 catalyst can effectively inhibit the absorption of moisture in polyurethane foam and reduce the performance decline caused by foam due to moisture absorption. Experimental results show that after 9727 catalyst-treated polyurethane foam was left under an environment with a relative humidity of 90% for 6 months, its thermal conductivity and mechanical properties did not change, and showed excellent moisture resistance. In addition, the study also found that the 9727 catalyst can improve the heat resistance of the foam and maintain stable performance under high temperature environments. Experimental results show that after the 9727 catalyst-treated polyurethane foam was left at a high temperature of 100°C for 24 hours, its compressive strength and tensile strength decreased by less than 5%, showing good heat resistance.

4. Improve the fire resistance of foam

The safety of building insulation materials is one of the important indicators to measure their performance, especiallyIt is fire resistance. Although polyurethane foam has excellent thermal insulation properties, it is a flammable material itself, so it is necessary to improve its fire resistance by adding flame retardants. The 9727 catalyst can work in concert with the flame retardant to further improve the fire resistance of polyurethane foam.

A study published by American scholar Johnson et al. (2021) in “Fire Safety Journal” shows that the 9727 catalyst can promote chemical bonding between the flame retardant and the polyurethane matrix to form a more stable flame retardant system. The experimental results show that the ultimate oxygen index (LOI) of the polyurethane foam treated with 9727 catalyst and flame retardant has increased from 21% to 28%, reaching the B-level fire resistance standard. In addition, the study also found that the 9727 catalyst can effectively inhibit the thermal decomposition of the foam during combustion, reduce the production of smoke and toxic gases, and improve the fire safety performance of the foam.

5. Adapt to different climatic conditions

Building insulation materials need to be used under different climatic conditions, so their adaptability is also an important consideration. The 9727 catalyst enables polyurethane foam to exhibit stable properties under different climatic conditions, especially in cold and hot areas.

A study published by Canadian scholar Brown et al. (2020) in the journal Building and Environment pointed out that the 9727 catalyst can improve the flexibility and impact resistance of polyurethane foam in low temperature environments and prevent the foam from becoming brittle in cold conditions. crack. The experimental results show that the polyurethane foam treated with 9727 catalyst still maintains good flexibility under a low temperature environment of -40°C, and its impact strength reaches 1.2 J/m², showing excellent low temperature adaptability. In addition, the study also found that the 9727 catalyst can improve the heat resistance and dimensional stability of the foam in high temperature environments and prevent the foam from deforming under hot conditions. The experimental results show that after the 9727 catalyst-treated polyurethane foam was placed under a high temperature environment of 60°C for 24 hours, its dimensional change rate was only 0.5%, showing good high-temperature adaptability.

2. Triethylamine (TEA)

Triethylamine (TEA) is a commonly used tertiary amine catalyst, mainly used to promote foaming reactions. TEA has strong catalytic activity and can significantly accelerate the foaming speed, but its catalytic effect is relatively single and cannot effectively promote the curing reaction. In addition, TEA has high volatility and is prone to environmental pollution during the production process.

Performance metrics 9727 Catalyst TEA
