Polyurethane has become an ideal material for building energy conservation

in recent years, polyurethane insulation materials have developed rapidly in China. Building energy conservation is a long-term and arduous task, and green building is a project that benefits the country and the people. As a strategic emerging industry, it has risen to the national industrial development strategy. Next year, Luoyang Construction Committee will strictly control the design, especially strengthen the special review of green building energy conservation. At the same time, all counties under the jurisdiction of Luoyang city should synchronously implement relevant measures for building energy conservation, which should be included in the assessment scope of the municipal government

it is reported that at present, there are many kinds of building exterior wall insulation materials in China, including rock wool, glass wool, foam ceramics, foam glass and polyurethane materials, among which polyurethane has superior performance and prominent characteristics, including low thermal conductivity, good thermal insulation performance, moisture-proof, waterproof, aging resistance, high temperature resistance and non melting. At the same time, polyurethane materials also have the advantages of low weight, high cutting accuracy and surface flatness of finished products, and will not produce harmful gases at high temperatures. However, developed countries in Europe and the United States have adopted 70% of Polyrigid foams in the field of building energy conservation, while only about 10% are used in China

lizhiqiang, President of China Polyurethane Industry Association, said that polyurethane is the best material for building energy conservation, but the public's awareness of it is very limited. The occurrence of fire accidents, the inadequacy of policies and standards, the lack of understanding of polyurethane by design units and construction enterprises, and the flooding of low-cost fake and shoddy products in the market have led to great misunderstanding of polyurethane by government departments, construction enterprises and the public, which has hindered the application of polyurethane exterior wall insulation materials

Zhu Changchun, Secretary General of China Polyurethane Industry Association, said: it is expected that in the coming years, the application proportion of polyurethane insulation materials in the construction field will reach 30% - 40%, and may even reach 50%. To provide convenience for people, the association will strive to build a platform to let the public know the performance of polyurethane, improve the market recognition of polyurethane insulation materials, further promote its application in construction projects, and promote building energy conservation

Li Jianbo, Deputy Secretary General of China Polyurethane Industry Association and Secretary General of isocyanate professional committee, believes that with the improvement of building energy efficiency standards and fire prevention requirements, as well as the completion of the preparation of polyurethane building insulation material standards, polyurethane rigid foam will become an important part of building insulation materials in China. Especially with the increasing number and density of high-rise buildings in China, the pressure on building insulation and fire prevention is higher than that in foreign countries. Secretary General Li Jianbo particularly stressed that polyurethane is actually not the ester industry and the construction industry should form such a consensus: thermosetting thermal insulation materials such as polyurethane rigid foam are superior to thermoplastic thermal insulation materials in terms of combustion performance, and it will definitely usher in the development opportunity commented by Mr. Ma Qingwei, chief operating officer of Xinda group

at the meeting, the heads of five polyurethane production enterprises, including Bayer, hongbaoli and gurek, made a special report, which covered the interpretation of building energy conservation and insulation and fire prevention policies, the quality control of polyurethane thin lime insulation system, and the application introduction of polyurethane exterior wall insulation system spraying equipment. After the meeting, the head of China Polyurethane Industry Association and representatives of hongbaoli and gurek received an exclusive interview from China Petroleum and chemical network television
