The building materials industry is the forerunner of the national economy. The development of various industrial sectors depends to a large extent on the development of the building materials industry. According to the needs of the construction of Sihua and the actual situation in China, the main way to develop the building materials industry, including thermal insulation materials, is to renovate the original traditional building materials, and to make full use of industrial waste and local resources. Development of new and versatile materials. Production practice has proved that insulation materials should consider the following aspects:

1. Accelerate the development of high-resistance fiber products: If it is to be developed, use inorganic fiber products that are not deformed or degraded under high temperature conditions. At present, it is necessary to comprehensively promote the aluminum silicate fiber used at 1000 ° C, and gradually promote the medium-grade aluminum silicate fiber used at 1300 ° C, further develop and promote new varieties of continuous fiber-forming and dry-formed carpets, so that high-temperature fire-resistant The fiber completes the intermediate test and is put into production. At the same time, we must pay attention to the research of fiber forming and application technology theory, and develop standards and test methods for high temperature resistant, fire resistant and heat insulating fibers, laying the foundation for the development of new varieties in the future.

2, the development of efficient, lightweight, multi-functional materials: the development of lightweight and efficient insulation materials, and combined with other materials, is a major trend in recent development at home and abroad. Modern construction and industrial equipment, many require insulation materials with lightweight or ultra-lightweight, high-strength, large-scale, high-efficiency and high temperature resistance, heat insulation, sound insulation, fireproof, waterproof, moisture-proof, wear-resistant and fire-resistant materials. For example, the development of organic cemented mineral wool, rock wool, aluminum silicate fiber, phosphate expanded perlite, high-quality aerated concrete, hollow insulation Boli, heat insulation and heat reflective glass. This has a great effect on saving energy, saving land and easing transportation.

3. Development of composite thermal insulation materials: development of new varieties of composite thermal insulation materials combining inorganic and organic, non-metallic and metal. Due to the advantages of various materials in composite materials, thermal insulation, strength and other aspects are excellent. Composite wall panels, composite walls. Such materials as Boli fiber reinforced cement, metal composite panels, sandwich panels, composite lightweight laminate panels, melamine plastic veneered calcium silicate panels, and the like. Asbestos cement board, mineral wool board and gypsum board are used to synthesize 12cm thick wallboard of 60kg per square meter. The thermal insulation performance is much better and lighter than the 37cm thick and 730kg/m2 brick wall.

4. Development of polymer synthetic materials: organic synthetic polymer materials, although poor in high temperature resistance, it has the characteristics of light weight, on-site injection and convenient construction. Building plastics in industrialized countries have accounted for 1 of the total output of plastics. /4. The United States has used 3.5 million tons of building materials in 1979 and is expected to reach 13 million tons by the end of this century. Varieties such as polyvinyl chloride, polyethylene, urea-formaldehyde, phenolic, polyester, polystyrene, etc., mostly foamed into foam, can also be sprayed as synthetic insulation fiber, in the construction and thermal work not exceeding 100 ° C Used on the device.

5. Use industrial waste as raw material as much as possible: use industrial waste to make building materials and thermal insulation materials, not only solve the pollution problem of waste slag discharge, but also make full use of waste, turn waste into treasure, and make the insulation material have good performance. For example, the dihydrated apricots discharged from the phosphate fertilizer plant can be made into calcium sulfate fiber and phosphate expanded perlite; the metallurgical slag can be used to produce mineral wool; the wood mill's shavings, wood and cement or other cement can be made into each Insulation materials; waste glass can be used as foam glass; fly ash can be made into fly ash aerated concrete. Agricultural by-product cotton rods, rice husks, reeds, etc. with cement or other cements can also be made into various insulation materials.

I. Define and purpose 
Bakelite Sheet is a hard, dense material made by applying heat and pressure to layers of paper or glass cloth impregnated with phenolic resin. These layers of laminations are usually of cellulose paper, cotton fabrics, synthetic yarn fabrics, glass fabrics or unwoven fabrics. When heat and pressure are applied to the layers, a chemical reaction (polymerization) transforms the layers into a high-pressure thermosetting industrial laminated plastic.

II. Technical requirement for surface 
The surface shall tidy and smooth, bubble, impurity are not allowed. But slight scratch and color punctum are allowed. Edge is to be cut smooth. The delamination and crackle on the end surface are not allowed. The surface shall tidy and smooth, bubble, impurity are not allowed. But slight scratch and color punctum are allowed. Edge is to be cut smooth. The delamination and crackle on the end surface are not allowed .
