Abstract

The invention discloses a technology for manufacturing silicone rubber materials, and particularly relates to silicone rubber for insulators and a method for manufacturing the silicone rubber. The silicone rubber comprises, by weight, 100 parts of raw rubber with the vinyl molar content of 0.2%, 30-80 parts of gas-phase white carbon black, 100-500 parts of aluminum hydroxide, 3-6 parts of hydroxyl silicone oil, 3-6 parts of vinyl hydroxyl silicone oil and 2-4 parts of stearic acid. The silicone rubber in a formula and the method have the advantages that various raw materials are reasonably selected and are reasonably matched with one another, the specific method is implemented, various parameters are strictly controlled in preparation procedures, accordingly, the silicone rubber is high in strength, sufficient in hardness and processability and difficult to deform, and requirements of the composite insulators can be completely met.
