Description

technical field [0001] The invention belongs to the technical field of rubber, and relates to a super-hydrophobic electric rubber and a preparation method thereof. Background technique [0002] Power grid system equipment is often exposed to different pollution conditions during long-term operation, and the operating environment is very harsh. The hydrophobicity of composite insulators will be lost over time during the operation of high-voltage lines, and the durability of hydrophobicity of composite insulators in special environments such as high pollution, high humidity, high dust, and high salt spray cannot meet the needs of grid anti-pollution flashover , Insulator shed hardening, embrittlement, pulverization, core rod crispness, pulverization and other problems will eventually lead to accidents such as insulator discharge, arcing, electric corrosion, and even flashover and short circuit fracture. The material of composite insulators belongs to rubber, and enhancing the...
