In recent years, China's polyurethane insulation materials have been developing rapidly. Building energy efficiency is a long-term and arduous task, and green buildings are projects that benefit the country and the people. As a strategic emerging industry, it has risen as a national industrial development strategy. Luoyang City Construction Committee should strictly control the design next year, and in particular, strengthen the special review of green building energy conservation. At the same time, counties under the jurisdiction of Luoyang City shall simultaneously implement relevant measures for building energy conservation and shall be included in the assessment scope of the municipal government.
It is reported that at present, there are many kinds of insulation materials for external walls of buildings in China, such as rock wool, glass wool, foam ceramics, foam glass and polyurethane materials. Among them, polyurethane has superior performance and features, with low thermal conductivity, good thermal insulation performance, and moisture resistance. , waterproof, anti-aging, high temperature and insoluble advantages. At the same time, polyurethane materials also have the advantages of low weight, high cutting precision, high surface flatness of the finished product, and no harmful gases at high temperatures. However, developed countries in Europe and the United States have adopted 70% of rigid foam in the field of building energy conservation, but China's use is still only about 10%.
Li Zhiqiang, chairman of the China Polyurethane Industry Association, said that polyurethane is the best material for building energy conservation, but public awareness of it is very limited. The occurrence of fire accidents, inadequacy of policies and standards, the lack of knowledge of polyurethanes by design and construction companies, and the low prices of fake and shoddy products flooded the market, leading to serious misunderstandings of polyurethanes by government agencies, construction companies, and the public. Polyurethane exterior wall insulation material application.
Zhu Changchun, secretary-general of the China Polyurethane Industry Association, said: "It is expected that in the next 3-5 years, the proportion of polyurethane insulation materials used in construction will reach 30%-40%, and may even reach 50%. In this regard, the association will work hard to build a platform for The public understands the performance of polyurethanes, increases market acceptance of polyurethane insulation materials, further promotes their application in construction projects, and promotes building energy conservation.â€
According to Li Jianbo, deputy secretary-general of China Polyurethane Industry Association and secretary general of Isocyanate Specialty Committee, with the improvement of building energy conservation standards and fire prevention requirements, and the completion of the preparation of polyurethane building insulation materials standards, polyurethane rigid foam will become an important part of China's building insulation materials. . Especially in the situation that more and more high-rise buildings in our country are growing in density, the pressure on building thermal insulation and fire protection is higher than in foreign countries. Secretary-General Li Jianbo particularly emphasized that the two major industries of polyurethane industry and construction industry should form such consensus: Polyurethane rigid foam and other thermosetting insulation materials are superior to thermoplastic insulation materials in combustion performance, and it will surely usher in good opportunities for development.
At the meeting, heads of five polyurethane production companies, including Bayer, Red Polaroid, and Graco, made special reports on the interpretation of building energy-saving insulation and fire protection policies, quality control of polyurethane thin-wall ash insulation system, and polyurethane exterior wall insulation system spraying. Equipment application introduction. After the meeting, representatives of China Polyurethane Industry Association and representatives of Red Polaris and Graco received an exclusive interview with China Petroleum and Chemical Network TV reporters.
