Abstract

The invention provides an antifouling flashover paint for electrical equipment and a preparation method thereof, belonging to the technical field of paint compositions. An antifouling flashover coating for electrical equipment, prepared from the following raw materials in parts by weight: 30-45 parts of room temperature vulcanized silicone rubber, 6-15 parts of fluorinated modified silicone resin, 5-10 parts of n-butanol, cyclic 5-15 parts of hexanone, 10-20 parts of dimethyl carbonate, 0.5-1.2 parts of bis(γ-trimethoxysilylpropyl)amine, 8-16 parts of filler and 0.2-1.0 parts of auxiliary agent. The anti-fouling flashover coating of the present invention can form a super-hydrophobic surface when coated on the surface of electrical equipment, has good self-cleaning ability, and effectively prevents the occurrence of pollution flashover of 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...
