Description

technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to a high-temperature-resistant organic silicon resin. Background technique [0002] Silicone resin (HS) combines the properties of inorganic materials and organic materials, and has excellent properties such as electrical insulation, ozone resistance, radiation resistance, flame retardant, water repellency, corrosion resistance, non-toxic, tasteless and physiological inertness. Resin-prepared molding compound composites have the characteristics of higher geometric stability, high-humidity complex environment, and chemical corrosion resistance. However, the existing silicone resins have poor high temperature resistance and cannot meet the market demand. Contents of the invention [0003] The object of the present invention is to provide a kind of high temperature resistant silicone resin aiming at the existing problems. [0004] The present invention is ach...
