Overview of Development Prospects of Thermal Insulation Exterior Wall Coatings in China

China is in the process of urbanization, with about 4 trillion real estate investments and more than 2 billion square meters of completed construction area each year. In the future, it will benefit from the regulation and control of the national energy conservation policy. In particular, the standards for building energy conservation will gradually increase, and the external insulation coatings for thermal insulation and insulation will usher in a new opportunity for development. Shi Yumei, deputy director of the Coatings Industry Association, pointed out that insulation coatings should emphasize practical application cases.

Talking about the development prospects of heat insulation and exterior wall coatings in China, Shi Yumei believes that the development of architectural coatings is closely related to the development of real estate. Real estate is booming and architectural coatings will be very good. In particular, we entered the “Twelfth Five-Year Plan” and everyone plans for a product structure in the direction of a low-carbon economy. The closest thing to energy conservation is currently thermal insulation coatings. A climax has now been set off because many factories and many scientific research institutes are engaged in such projects. Of course, the technical route is not the same, but in addition to the resin, there are some infrared reflective materials, the research route is not the same, and the functions to be performed are also different.

Most of the heat-reflective insulation coatings are still in the R&D stage and have yet to enter practical stage. Shi Yumei believes that there are several parts of the thermal insulation coating that are key to the technology. One is that the stain resistance is better, and the better the stain resistance, the longer the effect of the insulation coating is. This is a very big influence. the elements of. Then there is the problem of color. The current standard is to test this performance based on a white or very light paint, but there is a big difference between this and the actual application. Buildings are generally not particularly light-colored. . How to achieve the insulation effect of various colors is also a topic. There is another problem. Our current corporate publicity is limited to what standards the product meets, but it lacks practical application cases. Next, the development of our thermal insulation coatings should emphasize this aspect.

Insulation coatings can't just reach this standard. If companies come up with real engineering examples, the industry will grow faster.
