Organic silicon materials have been incorporated into the national medium and long-term development plan as the key high-tech new materials. In recent years, with the continuous development and improvement of the theory and technology of silicone chemistry, the silicone industry is developing towards the trend of high performance, multi-function, refinement and compounding. Sodium silicate is the main raw material for the synthesis of MQ silicone resin, and its price is low. In the synthesis process, it is not necessary to control the proportion of components too strictly, so the synthesis process is simple. The modification of MQ silicone resin is also very easy. It is easy to prepare modified resin for special use and develop functional MQ silicone resin. MQ silicone resin has great potential for industrial application and wide application.
 It can be used to prepare organosilicon defoamer with high temperature resistance and strong alkali resistance. The defoamer also has the advantages of non-toxicity and environmental protection. High branched reticular polymer was synthesized by adding high viscosity hydroxyl silicone oil and MQ silicone resin to improve the high temperature and alkali resistance of defoamer. Using MQ silicone resin containing SiH group or aryl alkyl group as crosslinking agent, and silicone resin containing vinyl group and high phenyl group under the action of platinum catalyst, the packaging material containing phenyl silicone resin was synthesized. The material has good compatibility and transparency, high hardness and high refractive index, and can be used for LED packaging and lens manufacturing. Carboxyl silicone oil modified by MQ resin was prepared by hydrosilylation of MQ hydrogenated silicone oil with silyl oleate catalyzed by Pt. Its combination with amino silicone oil can give fabric a better softness, smoothness and fullness.
