Where are rubber and plastic insulation materials widely used?

Since 1970s, foreign countries have attached great importance to the production and application of rubber-plastic insulation materials for buildings, and made great efforts to reduce energy consumption, thus reducing environmental pollution and greenhouse effect. Foreign rubber and plastic insulation materials industry has a long history, and rubber and plastic insulation materials for building energy conservation account for the vast majority. For example, from 1987, building rubber and plastic insulation materials account for about 8 1% of all insulation materials in the United States. The promulgation and implementation of rubber and plastic insulation materials and products and energy-saving laws and regulations are the influencing factors of building energy saving, involving a huge industrial group. The research and application of building rubber-plastic thermal insulation materials are paid more and more attention by countries all over the world, and new rubber-plastic thermal insulation materials are constantly emerging. Judging from the materials and varieties of building rubber-plastic insulation materials, the research on rubber-plastic insulation materials with polystyrene as the main raw material is extensive at home and abroad, but most of them are in the field of plates, such as polystyrene board, steel wire mesh sandwich composite internal and external wallboard, metal composite sandwich board and so on.

Although polystyrene board, as a kind of rubber and plastic thermal insulation material, has a good thermal insulation effect in use, due to the characteristics of the board, the connection between polystyrene board and the main body is mainly point-fixed, supplemented by surface-fixed, and the board needs to be spliced and bonded, which is not suitable for building thermal insulation with complex shapes, complicated construction technology and high comprehensive cost. At the same time, because the hydrophobicity of polystyrene board is not suitable for conventional hydrophilic materials, the quality of subsequent construction outside the surface layer is not easy to guarantee, and quality problems such as cracking, falling off and hollowing of surface mortar are prone to occur, which greatly restricts the use or construction of external decoration of buildings such as tiles and paints. Amorphous slurry rubber-plastic insulation material can overcome these shortcomings of plate, so it constitutes an important part of building insulation material. Developed countries such as Europe and America started early in the research and application of sizing rubber-plastic insulation materials, and the technology is relatively mature, and they have achieved fruitful results in the research and application. In the research and development of rubber-plastic thermal insulation slurry, at present, light and multifunctional composite slurry rubber-plastic thermal insulation materials are mainly used in developed countries. Compared with the traditional slurry rubber-plastic thermal insulation material, this slurry rubber-plastic thermal insulation material has low thermal conductivity and good safety and durability. At the same time, this kind of composite slurry rubber-plastic insulation material has excellent functionality, such as fluorine-free flame retardant polyurethane foam composite slurry rubber-plastic insulation material, ultra-light fully hydrophobic calcium silicate slurry rubber-plastic insulation material and so on. , can meet the requirements of different use conditions.
