In recent years, polyurethane organic thermal insulation materials have developed rapidly in China and become an important part of China's thermal insulation industry. Thermal insulation materials are based on increasing vapor porosity, low thermal conductivity and conductivity, and the thermal conductivity of materials is generally less than 0.174. W/mk, the apparent density should generally be less than 1000kg/m3, which is called thermal insulation material. With the development of China's society and the improvement of science and technology, the use of advanced insulation technology in the field of thermal insulation materials to improve production, create a comfortable living space and save energy has also received people's attention and recognition.
At the beginning of the founding of New China, most of China's thermal insulation materials used asbestos, cloth, cotton, diatomaceous earth, slag, straw, straw rope, rice husk, soil, straw rope wrapped in asbestos mortar, rice slag slag, asphalt Natural thermal insulation materials such as slag beating. After 1953, with the gradual development of large-scale capital construction projects, traditional natural insulation materials have been far from meeting the needs, and the transition from the use of natural thermal insulation materials to the use of artificial insulation materials began. However, until 1980, the development of thermal insulation materials in China was not fast. Since the reform and opening up, the production of thermal insulation materials has been developing at a high speed. At present, there are thousands of production enterprises. There are more than ten categories and hundreds of varieties of products. The thermal conductivity and weather resistance of the materials are greatly improved, and the temperature range is adapted from From -196 ° C to 1800 ° C, its material research and technology, production, and refined equipment levels have also been greatly improved.
The rapid development of thermal insulation materials such as mineral wool and products, glass wool and products, expanded perlite, castables, thermal insulation bricks and quartz sand in artificial thermal insulation materials has been well applied in industrial and civil applications. The development of society has made great contributions. However, when the society entered the 21st century and the explosive growth of scientific research technology, industrial and civil insulation materials also proposed new requirements, not only to achieve the effect of thermal insulation, but also proposed fire rating, fire resistance and temperature resistance, construction Convenience, low high heat coefficient, and high rework of materials.
