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.

Contribution of polyurethane catalyst 9727 to enhance durability of rigid foam

2月 15th, 2025 News

Introduction

Polyurethane (PU) is a polymer material produced by the reaction of isocyanate and polyol. Due to its excellent mechanical properties, chemical resistance, wear resistance and heat insulation, it is used in construction, automobiles, household appliances, etc. It has been widely used in many fields. Especially in the application of Rigid Polyurethane Foam (RPUF), polyurethane foam has become one of the first choices for modern building insulation materials due to its excellent insulation properties and lightweight properties. However, with the continuous growth of market demand and the increasing technical requirements, how to improve the durability of rigid foam has become the focus of industry attention.

The durability of rigid foam not only affects its service life, but also directly affects the energy efficiency and safety of the building. Traditional rigid foams may experience problems such as aging, degradation, uneven foaming during long-term use, resulting in a decline in physical properties, which in turn affects the stability and insulation effect of the overall structure. Therefore, it is particularly important to develop catalysts that can effectively improve the durability of rigid foams.

9727 As a new type of polyurethane catalyst, its application in rigid foam production has gradually increased in recent years. It has unique catalytic properties, which can promote the reaction between isocyanate and polyol at lower temperatures, reduce the occurrence of side reactions, thereby improving the cross-linking density of the foam and the uniformity of the microstructure. In addition, the 9727 can significantly improve the physical properties of the foam, extend its service life, and enhance its weather resistance and anti-aging capabilities. This article will conduct in-depth discussion on the contribution of 9727 catalyst to the durability of rigid foam, and combine new research results at home and abroad to analyze its mechanism of action, application advantages and future development direction.

9727 Basic Principles of Catalyst

9727 Catalyst is a highly efficient catalyst designed for polyurethane rigid foam, and its main components include tertiary amine compounds and metal salt compounds. This type of catalyst promotes the foam formation and curing process by accelerating the reaction between isocyanate (Isocyanate, -NCO) and polyol (Polyol, -OH). Specifically, the mechanism of action of the 9727 catalyst can be divided into the following aspects:

1. Accelerate the reaction rate

9727 Catalysts can significantly reduce the activation energy of the reaction between isocyanate and polyol, thereby accelerating the reaction rate. Under the action of traditional catalysts, the reaction of isocyanate with polyols usually requires a higher temperature to proceed, while the 9727 catalyst can effectively promote the progress of the reaction at lower temperatures. This not only shortens the foaming time, but also reduces side reactions caused by high temperatures, such as the autopolymerization of isocyanate and the hydrolysis of polyols. Studies have shown that after using the 9727 catalyst, the foaming time can be shortened by about 30%, and the reaction temperature can be reduced by 10-15°C (Reference: [1]).

2. Improve cross-link density

9727 Catalyst can not only accelerate the reaction rate, but also promote crosslinking reactions of more isocyanates and polyols by adjusting the reaction path, thereby increasing the crosslinking density of the foam. The increase in crosslinking density makes the molecular chain inside the foam tighter, forming a more stable three-dimensional network structure. This structure can effectively resist the influence of the external environment, such as temperature changes, humidity fluctuations and mechanical stresses, thereby improving the durability and mechanical properties of the foam. Experimental data show that the cross-linking density of rigid foams prepared with 9727 catalyst is about 20% higher than that of foams prepared with conventional catalysts (reference: [2]).

3. Improve the microstructure of foam

Another important feature of the 9727 catalyst is its ability to improve the microstructure of the foam. During the foam foaming process, the formation and growth of bubbles are the key factors that determine the performance of the foam. The 9727 catalyst can effectively control the size and distribution of bubbles, avoiding too large or too small bubbles, thereby ensuring the uniformity and denseness of the bubbles. A uniform pore size distribution not only helps improve the insulation performance of the foam, but also enhances its mechanical strength and compressive resistance. Scanning electron microscopy (SEM) observations showed that the foam prepared with 9727 catalyst had a more uniform pore size distribution, moderate bubble wall thickness, and no obvious defects (reference: [3]).

4. Reduce side effects

In the preparation process of polyurethane foam, in addition to the main reaction, some side reactions may also be accompanied by some side reactions, such as the autopolymerization of isocyanate, the hydrolysis of polyols, and the formation of carbon dioxide. These side reactions not only consume raw materials, but also lead to a decrease in foam performance. The 9727 catalyst selectively promotes the main reaction and inhibits the occurrence of side reactions, thereby improving the utilization rate of raw materials and the quality of foam. Studies have shown that after the use of the 9727 catalyst, the incidence of side reactions was reduced by about 40%, and the density and hardness of the foam were significantly improved (references: [4]).

5. Extend foam life

9727 The efficient catalytic action of the catalyst is not only reflected in the preparation process of the foam, but also has a positive impact on its long-term performance. Since the 9727 catalyst can improve the crosslink density and microstructure uniformity of the foam, the foam shows better weather resistance and anti-aging during long-term use. Experimental results show that after 6 months of aging test, the physical performance retention rate of foams prepared with 9727 catalyst still reached more than 90%, while foams prepared with traditional catalysts showed significant performance decline (Reference: [5 ]).

To sum up, the 9727 catalyst significantly improves the durability and comprehensive performance of rigid foam through various mechanisms such as accelerating the reaction rate, increasing the crosslinking density, improving the microstructure of the foam, and reducing side reactions. Next, we will discuss in detail the specific parameters of the 9727 catalyst and its performance in practical applications.

To better understand the performance characteristics of the 9727 catalyst and its application in the production of rigid foams, the following are the main product parameters of the catalyst. These parameters not only reflect the physicochemical properties of the 9727 catalyst, but also provide a basis for its choice in different application scenarios.
