Abstract

The invention provides a novel external insulating anti-pollution flashover spraying composite material of an electric transmission line and belongs to the technical field of coating compositions. Thenovel external insulating anti-pollution flashover spraying composite material is prepared from the following raw materials in parts by weight: 30-40 parts of silicone rubber, 20-30 parts of fluorosilicone modified epoxy resin, 10-20 parts of an aluminate coupling agent, 2-7 parts of nano silicon dioxide, 1-5 parts of diatomite, 5-10 parts of calcium carbonate, 0.01-0.06 part of tributyl phosphate, 2-7 parts of ethyl acetate, 2-7 parts of a phosphate modified acrylic emulsion, 0.1-0.5 part of a dispersant, 0.001-0.004 part of a surfactant, 0.2-0.8 part of a curing agent and 30-50 parts of propylene glycol methyl ether acetate. The average static contact angle of the obtained composite coating is greater than or equal to 152 degrees, and the minimum static contact angle is greater than orequal to 145 degrees. The coating is excellent in mechanical property and self-cleaning performance, and is suitable for external insulating anti-pollution flashover of the electric transmission line.

Description

technical field [0001] The invention belongs to the technical field of coating compositions, and in particular relates to a novel anti-pollution flashover spraying composite material for external insulation of power transmission lines. Background technique [0002] Pollution flashover refers to the deposition of dust particles in the atmosphere on the surface of insulators that have been operating outdoors for a long time, gradually forming a pollution layer. The substance gradually dissolves in water to form a conductive film on the surface of the insulator, thereby increasing the surface conductivity and reducing the insulation performance, resulting in flashover discharge on the wet surface of the insulator (referred to as pollution flashover). The three main factors that cause pollution flashover are insulator surface pollution, pollution layer wetting and voltage action. The pollution flashover process mainly includes four stages: insulator surface pollution, pollution ...
