Rubber and plastic thermal insulation materials have been used in building energy conservation in some developed countries since the late 1970s. The construction industry is forced to implement energy conservation standards in new buildings and use rubber and plastic thermal insulation materials. The application of rubber and plastic thermal insulation materials in developed countries and the attention paid to building energy conservation and some measures taken in these countries have achieved great results, and building energy consumption has decreased significantly. For example, after Denmark used rubber and plastic insulation materials, the heating area in 1985 increased by 30% compared with 1972, but the heating energy consumption decreased by 3.18 million tons of standard coal. It can be seen that foreign building energy conservation laws and regulations have achieved significant social and economic benefits for more than 30 years.
Rubber and plastic insulation materials are elastic closed cell elastic materials, which are soft, flexible, cold resistant, heat resistant, flame retardant, waterproof, low thermal conductivity, shock absorption, sound absorption and other excellent properties. They can be widely used in central air conditioning, building, chemical, textile, metallurgy, communication, vehicles, electrical appliances and other industries and some kinds of cold and hot medium pipes and containers, which can achieve the effect of reducing cold loss and heat loss. In addition, the construction is simple, the appearance is clean and beautiful, and the product does not contain fiber dust, and does not breed any harmful substances such as mold, so it is a new generation of high-quality thermal insulation material spanning the century.
The promulgation and implementation of rubber and plastic thermal insulation materials and products, and energy conservation laws and regulations are the influencing factors of building energy conservation, involving a huge industrial group. The development and application of building rubber and plastic thermal insulation materials are more and more widely valued by all countries in the world, and new rubber and plastic thermal insulation materials are constantly emerging. From the perspective of materials and varieties of building rubber and plastic insulation materials, research on rubber and plastic insulation materials with polystyrene as the main raw material is relatively extensive at home and abroad, but most of them are in the field of plates, such as polystyrene board, steel wire grid sandwich composite inner and outer wall panels, metal composite sandwich panels, etc. Although polystyrene board as rubber and plastic thermal insulation material has good thermal insulation effect in use, due to the characteristics of the board, when connecting with the main body in construction, the polystyrene board is mainly fixed at the point, supplemented by the surface. The boards should be spliced and bonded, which is not suitable for the thermal insulation of buildings with complex shapes. The construction process is complex and the comprehensive cost is high. At the same time, because the hydrophobicity of polystyrene board is not suitable for conventional hydrophilic materials, it is difficult to ensure the quality of subsequent construction beyond its surface course, and it is easy to have quality problems such as cracking, falling off and hollowing of surface course mortar, which greatly restricts the use or construction of external decoration of buildings, such as face tiles and coatings. Amorphous paste rubber and plastic insulation materials can overcome these shortcomings of plates, so it constitutes an important part of building thermal insulation materials. Developed countries such as Europe and the United States started early in the research and application of paste rubber and plastic insulation materials, and the technology is relatively mature, which has achieved fruitful results in research and application.
In terms of research and development of rubber and plastic insulation material paste, at present, the developed countries mainly focus on light multi-functional composite paste rubber and plastic insulation materials. The properties of this kind of paste rubber and plastic insulation materials are significantly improved compared with traditional paste rubber and plastic insulation materials, such as low thermal conductivity, good use safety and durability. At the same time, this kind of composite paste rubber and plastic insulation materials also have excellent functionality, such as non freon flame retardant polyurethane foam composite paste rubber and plastic insulation materials, total hydrophobic calcium silicate paste rubber and plastic insulation materials, which can meet the requirements of different use conditions.
Foreign countries also attach great importance to the environmental protection of rubber and plastic insulation material industry. They actively develop "green" rubber and plastic insulation material products. From raw material preparation (mining or transportation), product production and use, and future treatment, it is required to save resources and reduce the harm to the environment. Rubber and plastic insulation material industry is a very successful example of foreign resources recycling.
