Let us enter this world full of innovation and possibilities and explore how the amine catalyst BL11 changes the future of the waterproof materials industry!

1. Development history and current status of waterproof materials

(I) The historical evolution of waterproof materials

Waterproof materials are one of the important symbols of the development of human civilization. As early as around 3000 BC, the ancient Egyptians used natural asphalt as waterproof coating to protect their granaries from moisture. By 278 BC, the Qin Dynasty in China built the Dujiangyan Water Conservancy Project, which used a special clay mixture to enhance the waterproofing performance of the embankment. The ancient Romans invented concrete mixed with volcanic ash. This material not only has high strength, but also has excellent impermeability resistance, and is still widely studied today.

After entering the industrial age, waterproof materials gradually shifted from natural raw materials to artificial synthetic materials. At the end of the 19th century, rubber-based waterproof coatings began to be used in roof waterproofing projects; in the mid-20th century, polymer materials such as polyurethane (PU) and epoxy resins became the mainstream choice. In recent years, with the development of nanotechnology, functional waterproof materials such as self-healing coatings and breathable membranes have emerged, greatly improving the waterproof effect and service life.

(II) Problems with current waterproofing materials

Although modern waterproof materials have a wide variety and superior performance, they still face some urgent problems:

Insufficient durability: Many waterproof materials tend to age when exposed to ultraviolet rays, acid rain or high temperature environments for a long time, resulting in the failure of the waterproof function.
High construction complexity: Some high-performance waterproof materials require complex construction processes, which increases project costs and time investment.
Poor environmental protection performance: Some traditional waterproof materials contain volatile organic compounds (VOCs), which pose a threat to the environment and human health.
Limited adaptability: Faced with different climatic conditions and special application scenarios (such as underground engineering, bridges and tunnels, etc.), existing materials often find it difficult to take into account multiple needs.

The existence of these problems has made the development of more efficient, environmentally friendly and durable waterproof materials an inevitable trend in the development of the industry. It is against this background that the amine catalyst BL11 stands out with its unique properties, injecting new vitality into the field of waterproof materials.

2. Technical parameters and advantages of amine catalyst BL11

(I) What is amine catalyst BL11?

Amine catalyst BL11 is a highly efficient catalyst specially used in polyurethane waterproofing materials. It significantly improves the cross-linking density and curing speed of polyurethane materials by promoting the reaction between isocyanate (NCO) and hydroxyl (OH), thereby improving the overall performance of the material. Compared with traditional amine catalysts, BL11 has higher activity, lower toxicity and better storage stability.

In the waterproofing renovation project of a subway station in Shanghai, the construction party used polyurethane waterproof coating containing BL11. Due to the abundant groundwater and high humidity in the area, traditional waterproof materials often experience leakage problems. After a year of use monitoring, no leakage points were found in the new coating, and the surface was smooth and smooth and with good adhesion.

2. Construction of Beijing Winter Olympics Venues

During the construction of the Beijing Winter Olympics venue, the roof waterproofing system uses high-performance polyurethane materials containing BL11. Even under extreme cold conditions (low temperatures up to -30°C), the coating still maintains good flexibility and waterproof performance, ensuring the safe operation of facilities during the event.

IV. Future development direction of amine catalyst BL11
