Term amine polyurethane catalyst BL-17: The “invisible hero” of building insulation materials

In the field of modern architecture, the importance of insulation materials is self-evident. They are like wearing a “thermal underwear” on buildings, which not only makes the indoors warm in winter and cool in summer, but also significantly reduces energy consumption and contributes to the environmental protection cause. In this process, the tertiary amine polyurethane catalyst BL-17 plays a crucial role. It is like the “behind the scenes director” in this insulation revolution, silently promoting the development of high-performance insulation materials.

What is tertiary amine polyurethane catalyst BL-17?

Definition and Function

Term amine polyurethane catalyst BL-17 is a highly efficient chemical catalyst, mainly used to accelerate the foaming reaction and curing process of polyurethane foam. Its existence is like a key that can quickly open the door to chemical reactions, allowing polyurethane foam to achieve ideal density and strength in a short period of time. This catalyst is particularly suitable for the production of rigid polyurethane foam and is widely used in thermal insulation of building walls, roofs, floors and other parts.

Chemical structure and performance characteristics

The molecular structure of BL-17 contains specific tertiary amine groups, which have extremely strong catalytic effects on the reaction between isocyanate and polyol. Its main components include N,N-dimethylcyclohexylamine and other auxiliary components, ensuring its stability and efficiency under different environmental conditions. Here are some key performance parameters of BL-17:

parameter name	parameter value
Appearance	Colorless to light yellow transparent liquid
Density (25°C)	0.89 g/cm³
Viscosity (25°C)	40-60 mPa·s
Activity level	High
Compatibility	Good compatibility with most polyurethane raw materials

The application advantages of BL-17 in building insulation materials

Improving foam performance

Polyurethane foam produced using BL-17 has a higher cell cell ratio and a more uniform cell structure, which greatly improves the insulation effect of the foam. Imagine that if traditional foam is compared to a loose sponge, then the foam treated by BL-17 is like a tightly arranged honeycomb, each small unit is tightly connected, effectively preventing it.Loss of heat.

Enhance the construction convenience

Because BL-17 can significantly shorten the curing time of foam, it greatly improves construction efficiency. For construction sites, this means that the laying of the insulation layer can be completed faster, reducing construction cycles and reducing costs. It’s like equiping the construction team with a high-speed printer. The work that originally took one day to complete can now be done in a few hours.

Improve environmental performance

BL-17 itself does not contain any harmful substances, and there are few by-products produced by its catalytic process, which is extremely beneficial to environmental protection. In addition, by optimizing the foam structure, the use of raw materials can be reduced, thereby further reducing carbon emissions. It can be said that BL-17 not only makes the building more energy-saving, but also makes the entire production process greener.

Domestic and foreign research progress and application cases

Domestic research status

In recent years, domestic scientific research institutions have increasingly conducted research on BL-17. For example, a study from Tsinghua University showed that the use of BL-17 can reduce the thermal conductivity of rigid polyurethane foam to below 0.02 W/(m·K), which is far superior to traditional insulation materials. At the same time, the study also found that the application of BL-17 can significantly improve the compressive strength and dimensional stability of foam, which is particularly important for high-rise buildings.

International Application Examples

In foreign countries, Germany’s BASF has long applied BL-17 technology to its high-end building insulation products. Their data show that after using the BL-17 catalyst, the product’s service life has been extended by more than 30%, and it still maintains good performance in extreme climates. In addition, DuPont, the United States, has also adopted similar technologies in its series of new insulation materials, achieving significant market response.

Conclusion: Future Outlook

With the continuous increase in global energy conservation and environmental protection requirements, the tertiary amine polyurethane catalyst BL-17 will surely play a greater role in the field of building insulation. It not only represents an advanced technical means, but also an important force in promoting the development of green buildings. As an old proverb says: “If you want to do something well, you must first sharpen your tools.” BL-17 is the sharp tool that helps us build a more comfortable, safe and environmentally friendly home. In the future, we can look forward to more innovative insulation solutions based on BL-17, so that every building can become a model for energy conservation and emission reduction.
