In the late 1970s, rubber foam insulation materials began to use building energy conservation in some developed countries. The mandatory construction industry implemented energy-saving standards in new buildings, using rubber-plastic insulation materials, and the application of rubber-plastic insulation materials in developed countries. The emphasis on building energy efficiency and some effective measures have been taken, and these countries have achieved great results, and building energy consumption has dropped significantly. For example, after using rubber and plastic insulation materials in Denmark, the heating area increased by 30% in 1985 compared with 1972, but the heating energy consumption was reduced by 3.18 million tons of standard coal. This shows that foreign building energy conservation regulations have been remarkable for more than 30 years. Social and economic benefits.
Rubber and plastic insulation material is elastic closed-cell elastic material, which is soft, resistant to winding, cold, heat, flame retardant, waterproof, low thermal conductivity, shock absorption, sound absorption and other excellent properties. It can be widely used in central air conditioning, construction, chemical industry. , light textile, metallurgy, transmission, vehicles, electrical appliances and other industries and parts of various types of cold and heat medium pipes, containers, can achieve the effect of reducing cold damage and heat loss. In addition, the construction is simple, the appearance is neat and beautiful, and the product does not contain fiber dust, and does not breed any harmful substances such as mold, so it is a high-quality cross-century new generation thermal insulation material.
The promulgation and implementation of rubber and plastic insulation materials and products and energy conservation regulations are the influencing factors affecting building energy efficiency, involving a large industrial group. The development and application of building rubber and plastic insulation materials are receiving more and more attention from all over the world. Materials are constantly emerging. From the perspective of the materials and varieties of building rubber and plastic insulation materials, the 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 and steel wire mesh. Sandwich composite inner and outer wall panels, metal composite sandwich panels, etc. Although polystyrene board has good thermal insulation effect as rubber and plastic insulation material in use, due to the characteristics of the board, the polystyrene board is mainly fixed by point and fixed by surface when it is connected with the main body during construction. It is necessary to splicing and bonding, and it is not suitable for the insulation of buildings with complex shapes. The construction process is complicated and the comprehensive cost is high.
At the same time, because the hydrophobicity of the polystyrene board is not suitable for the conventional hydrophilic material, the subsequent construction quality outside the surface layer is not easy to ensure, and the quality problems such as cracking, falling off, and hollowing of the surface mortar are prone to occur on the building. Exterior decoration such as the use of bricks and coatings or construction constitutes a major constraint. The amorphous slurry rubber insulation material can overcome these shortcomings of the sheet metal, so it constitutes an important part of the building insulation material. Developed countries such as Europe and the United States started early in the research and application of slurry rubber and plastic insulation materials, and the technology is relatively mature, and has been effective in research and application.
In the research and development of rubber and plastic insulation material slurry, at present, the developed countries are mainly lightweight multi-functional composite slurry rubber and plastic insulation materials. The performance of such slurry rubber and plastic insulation materials is significantly improved compared with the traditional slurry rubber insulation materials, such as low thermal conductivity and good safety and durability. At the same time, this kind of composite slurry rubber and plastic insulation material has excellent functionality, such as non-French flame retardant polyurethane foam composite slurry rubber and plastic insulation material, ultra-light full-water calcium silicate slurry rubber insulation material. Etc., can meet the requirements of different use conditions.phenolic insulation manufacturers
The environmental protection issues of the rubber and plastic insulation materials industry are also highly valued abroad, and the development of “green” rubber and plastic insulation materials products, from raw material preparation (mining or transportation), product production and use, and future disposal issues, are required to maximize Save resources and reduce environmental damage. The rubber and plastic insulation material industry is a very successful example of the recycling of foreign resources.
