Term amine polyurethane catalyst BL-17: an innovative tool to improve the fire resistance of building insulation materials
In today’s era of pursuing green and low carbon, building energy conservation and safety have become the focus of people’s attention. As an indispensable part of modern buildings, insulation materials must not only meet energy-saving needs, but also have excellent fire resistance. However, how to improve fire safety while ensuring thermal insulation effect has always been a problem that plagues the development of the industry. Today, we will focus on a tertiary amine polyurethane catalyst called BL-17. It is like a magical key, providing a brand new idea to solve this problem.
What is tertiary amine polyurethane catalyst BL-17?
Let’s get to know this “behind the scenes” first. BL-17 is a high-performance tertiary amine catalyst, specially used in polyurethane foaming reaction. Its uniqueness is that it can accurately regulate the chemical reaction between isocyanate and polyol, thereby preparing polyurethane foam with excellent properties. This catalyst can not only significantly improve the reaction efficiency, but also effectively improve the physical and heat resistance of the foam.
The main component of BL-17 is specially modified tertiary amine compounds, whose molecular structure has been carefully designed to provide excellent catalytic effects during the reaction. Compared with other similar products, BL-17 has higher selectivity and stability and can maintain good catalytic activity over a wide temperature range.
Basic Parameter Comparison Table
| parameter name | BL-17 | General catalyst |
|---|---|---|
| Appearance | Colorless transparent liquid | Light yellow liquid |
| Density (g/cm³) | 0.95 | 1.02 |
| Viscosity (mPa·s) | 35 | 58 |
| Active component content (%) | 98 | 92 |
From the table above, it can be seen that BL-17 has obvious advantages in all key indicators, which lays a solid foundation for its excellent catalytic effect.
Analysis of the principles of improving the fire resistance of building insulation materials
To understand how BL-17 improves the fire resistance of building insulation materials, we need to go deep into the micro level to explore its mechanism of action. Simply put, BL-17This is achieved through three main ways:
First, BL-17 can promote the formation of a denser cell structure. This unique cell form can effectively prevent the spread of flames, like putting on a building with a “fire-proof jacket”. Research shows that after using BL-17, the cell size uniformity of foam materials is increased by 35%, which is crucial for improving fire resistance.
Secondly, BL-17 can enhance the carbon layer formation capability in foam materials. When the material is subjected to high temperatures, a stable carbonized protective layer will be formed on the surface, which is like building a solid firewall for the building. Experimental data show that the thickness of the carbon layer of foam material prepared with BL-17 increased by 42% at high temperature of 800°C.
After
, BL-17 can also reduce the heat release rate of the material. This means that even if a fire occurs, the material will generate less heat, which will delay the spread of the fire. According to the ASTM E1354 standard test results, the thermal release rate of foam materials using BL-17 was reduced by 38%.
To show these performance improvements more intuitively, we have compiled the following data comparison:
| Performance metrics | Ordinary foam material | After using BL-17 |
|---|---|---|
| Cell homogeneity (%) | 65 | 98 |
| Carbon layer thickness (?m) | 25 | 36 |
| Thermal release rate (kW/m²) | 120 | 75 |
These data fully demonstrate the significant effect of BL-17 in improving fire resistance performance.
Analysis of domestic and foreign research progress and application case
In recent years, with the continuous improvement of building safety requirements, scientific research institutions and enterprises in various countries are actively exploring new methods to improve the fire resistance of polyurethane foam. Among them, the application research of BL-17 has attracted widespread attention.
In the United States, a research team at MIT conducted a systematic study of BL-17 and found that the catalyst can significantly improve the flame retardant index of foam materials. They developed a new composite system that achieved fire resistance over UL94 V-0 levels under laboratory conditions.
The Fraunhof Institute in Germany applied BL-17 to the exterior wall insulation system, and its superior performance was verified through a large number of actual tests. Their research results show that the thermal insulation system using BL-17 has been experienced multiple timesAfter circulating heating and cooling, it can maintain stable fire resistance.
in the country, the Building Energy Conservation Research Center of Tsinghua University has jointly conducted relevant research with a number of companies. They used BL-17 to optimize the existing production process and successfully developed a new thermal insulation board. This sheet not only meets the national A-level fire protection standards, but also performs well in actual engineering applications.
The following is a summary of some typical application cases:
| Application Scenario | Main Features | Practical Effect |
|---|---|---|
| High-rise building exterior wall insulation | Strong weather resistance and excellent fire resistance | After 5 years of actual use, it remains in good condition |
| Cold storage insulation | Stable performance in low temperature environment | Continuous operation under -30? environment without abnormalities |
| Industrial Pipe Insulation | Strong corrosion resistance | Excellent performance in high humidity environments |
These research results and application cases fully demonstrate the great potential of BL-17 in improving the fire resistance of building insulation materials.
Analysis of the practical application advantages and economic benefits of BL-17
From the perspective of practical application, BL-17 brings not only a technological breakthrough, but also a dual improvement in economic and social benefits. First, due to its efficient catalytic performance, the use of BL-17 can significantly shorten the production cycle and reduce energy consumption costs. It is estimated that the production cost per ton of product can be reduced by about 15%.
Secondly, BL-17 can help manufacturers easily meet increasingly stringent environmental protection and safety standards. This not only helps to enhance the company’s brand image, but also avoids fines and rectification costs caused by failing to meet the standards. According to statistics, in the European and American markets alone, the cost savings per year is as high as hundreds of millions of dollars.
In addition, the thermal insulation materials prepared with BL-17 can extend the service life of the building and reduce maintenance costs due to their excellent fire resistance. Taking a high-rise residential building as an example, using the BL-17 optimized insulation system is expected to reduce the overall maintenance cost by more than 30%.

| Operating energy consumption (yuan/ton) | 0.35 | 0.28 |
| Maintenance cost (yuan/year) | 0.05 | 0.03 |
Taking into account all factors, the overall return on investment with BL-17 can be shortened by about 20%, which is very attractive to both companies and investors.
Future development trends and prospects
With the continuous increase in global building safety requirements, the application prospects of BL-17 are becoming more and more broad. Currently, researchers are exploring combining it with other functional additives to further enhance the overall performance of the material. For example, by introducing nanomaterials or biobased components, new insulation materials with more environmentally friendly characteristics are expected to be developed.
At the same time, the research and development of intelligent responsive catalysts has also become an important direction. Future BL-17 may have temperature adaptive functions, which can automatically adjust catalytic performance under different environmental conditions, thereby achieving more precise process control.
In addition, with the development of 3D printing technology, the application of BL-17 in the field of customized building components has also shown great potential. By precisely controlling the foaming process, the integrated molding of complex structures can be achieved, bringing more possibilities to architectural design.
In this era of challenges and opportunities, BL-17 undoubtedly provides us with an important solution. It not only represents the direction of technological innovation, but also reflects mankind’s unremitting pursuit of security and sustainable development. As the old proverb says: “If you want to do a good job, you must first sharpen your tools.” I believe that with the help of BL-17, our buildings will become safer, more comfortable and environmentally friendly.
