Abstract

The invention belongs to the technical field of coating preparation, and discloses coating preventing pollution flashover and a preparation method thereof. The coating includes, by weight, 15-20 partsof olefinic acid resin, 15-20 parts of rosin, 20-30 parts of an anti-contamination agent, 15-20 parts of a pigment filler, 15-30 parts of a solvent, 2-4 parts of an anti-settling agent and 5-10 partsof Pickering emulsion. The coating preventing pollution flashover has better adhesion and longer shelf life, can effectively inhibit and prevent the adhesion and growth of the living body on the insulator, and avoid the occurrence of a pollution flashover accident.

Description

technical field [0001] The invention relates to the technical field of paint preparation, in particular to an antifouling flashover paint and a preparation method thereof. Background technique [0002] The setting of the power grid and power transmission play a pivotal role in the national economy and life. In the areas where the power lines pass, industrial pollution, salt spray from the sea breeze, dust in the air and other pollutants gradually accumulate and adhere to the surface of the insulator, forming pollution. Layer, this dirty layer contains acid, alkali and salt components. When dry, the dielectric strength is high and the conductivity is weak, but when it is wet with water, the dielectric strength will decrease and it will have strong conductivity. Therefore, when encountering bad weather such as rain, snow melting, fog, etc., the insulation strength of dirty insulators will be greatly reduced, and the conductivity will be greatly improved, causing insulators to ...
