Abstract

The invention belongs to the technical field of coating compositions and provides anti-pollution flashover coating for electrical equipment and a preparation method of the anti-pollution flashover coating. The anti-pollution flashover coating is prepared from, by weight, 30-45 parts of room-temperature vulcanized silicon rubber, 6-15 parts of fluorinated modified organic silicon resin, 5-10 partsof n-butyl alcohol, 5-15 parts of cyclohexanone, 10-20 parts of dimethyl carbonate, 0.5-1.2 parts of bis(gamma-trimethoxysilylpropyl)amine, 8-16 parts of filler and 0.2-1.0 part of an auxiliary agent.The anti-pollution flashover coating applied to the surface of the electrical equipment is capable of forming a super-hydrophobic surface and is excellent in self-cleaning performance and effective in prevention of pollution flashover of the electrical equipment.

Description

technical field [0001] The invention belongs to the technical field of paint compositions, and in particular relates to an antifouling flashover paint for electrical equipment and a preparation method thereof. Background technique [0002] The development of my country's economy is inseparable from the development of the electric power industry. The development of the economy has gradually increased people's demand for the reliability of power supply in the power system. To obtain a reliable power supply system, it is first necessary to ensure the security of the power supply system. As an important part of the power system, the external insulation of electrical equipment is the focus of ensuring the stability of the power system. Pollution flashover and rain flashover are two main factors that threaten the stability of external insulation. Scholars at home and abroad have conducted systematic and in-depth research on pollution flashover. Power grids in various countries h...
