DBU can significantly improve the physical and chemical properties of green building materials by catalyzing the polyurethane reaction. For example, in rigid polyurethane foams, DBU can promote the reaction between isocyanate and polyol to form a denser foam structure, thereby improving the thermal insulation properties and mechanical strength of the material. This improvement not only helps reduce energy consumption in buildings, but also extends the service life of the materials.

2. Reduce production costs

Traditional polyurethane catalysts are often expensive and prone to harmful by-products, while DBU effectively reduces production costs with its efficient catalytic performance and low dosage requirements. In addition, the high thermal stability and low volatility of DBU also reduce losses during production and transportation, further improving economic benefits.

3. Promote the development of environmental protection technology

The application of DBU can also promote technological innovation in the field of green building materials. For example, by optimizing the formulation and process conditions of DBU, more environmentally friendly polyurethane materials can be developed, such as fluorine-free foaming agent systems and recyclable polyurethane materials. These innovations not only meet current environmental protection requirements, but also provide more possibilities for future development of the construction industry.
