Silicone resin-insulating material
The first application technology of silicone resin as coating was silicone resin impregnated fiberglass cloth tape, which was used as a protective layer for wire insulation on U.S. Navy submarines. my country developed silicone resin in the 1950s, and at the initial stage it was mainly used for insulation impregnation of H-class motor coils, H-class motor wire-covered wires and glass fiber cloth for slot insulation, and glass fiber insulation sleeves. , Mica tape for insulation, etc.
Therefore, pure silicone resin as an insulating coating is the oldest silicone product. The pure silicone resin produced by the old process has the advantages of high temperature resistance, weather resistance, and good insulation that other general organic resins cannot match. However, it also has disadvantages such as high curing temperature, long curing time, poor adhesion, and back-adhesion at high temperatures. With the development of science and technology and the development of new materials, silicone is no longer the only H-level insulating paint, and high-performance organic resin H-level insulating paints such as polyimide and polyester have emerged.
Therefore, in order to meet the needs of the situation, silicone coatings must develop in the direction of new processes, new technologies, new varieties, and new uses. Through the reform of the production process of silicone resin and the use of organic resin and silicone resin cold blending or copolymerization modification and other new technologies, the three defects of silicone resin have been greatly improved, and the application field of silicone coatings has also been expanded.
