Organosilicon molding plastics






In 1960s, China's aviation industry urgently needed a kind of arc resistant silicone mold plastic which can withstand strong current and high voltage for making micro switches. Beijing Research Institute of chemical industry has successfully developed silicone resin which is directly hydrolyzed from methyltrichlorosilane and made into arc resistant mold plastic with asbestos filler, which has solved the urgent need of aviation industry. The material was transferred to Shanghai resin factory for production. However, users still need this kind of material, so they have to ask for help from Chenguang Chemical Research Institute, which moved to Sichuan Province. In order to meet the urgent needs of users, Wu Shengquan et al. Of the Institute used the hydrolysis condensation route from methyltriethoxysilane as the starting material to prepare the silicone resin for molding plastics with satisfactory performance, so as to solve the urgent needs of users.








Silicone resin sealing material






In the late 1960s, with the development of China's electronic industry, it is necessary to use silicone sealing materials with excellent electrical insulation, high temperature resistance, moisture-proof and non combustion to package large and small power diodes, triodes, resistors, capacitors, integrated circuits and other electronic devices. In China, Zhang Xinghua, he Jigang, et al. Of the Institute of chemistry of the Chinese Academy of Sciences, and Zhang Jikai, Li Yansheng, et al. Of Shanghai resin factory were early engaged in the development of such resins. They developed a variety of products to fill the domestic gap.








Silicone resin modified coating






The general silicone is mostly composed of polymethylsiloxane and polyphenylsiloxane. The compatibility of silicone resin containing phenyl and organic resin is better than that of methyl silicone resin. The temperature resistance and water resistance of general coatings can be improved by introducing phenyl silicone into them. In the coating industry, high-performance siloxane containing coating can be prepared by blending or copolymerization of phenyl containing silicone resin. As early as the 1960s, Tianjin paint factory and Shanghai resin factory successfully developed the coating of silicone modified synthetic resin. A variety of good properties have been developed, such as silicone modified epoxy resin with good heat resistance and adhesion.
