Abstract

The invention relates to a long-lasting antifouling flashover coating with high hydrophobicity and corrosion resistance and its application, which consists of water-based fluorocarbon emulsion resin, aromatic polyurethane acrylate, silicone resin, dimethylaminoethyl acrylate, modified Poly(3,4-ethylenedioxythiophene)-polystyrene sulfonic acid, diluent, leveling agent, graphene, propylene glycol, magnesium chloride, nano-silver powder, organic bentonite, the coating of the present invention has strong water resistance, Pollution and corrosion resistance, the coating surface significantly reduces the adsorption effect on water droplets, dust and charged particles, and has good self-cleaning and weather resistance, with high application prospects.

Description

technical field [0001] The invention belongs to the field of paint preparation, in particular to a long-acting anti-pollution flashover paint with high hydrophobicity and corrosion resistance and its application. Background technique [0002] In the area where the transmission line passes, 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 a pollution layer. This dirt contains acid, alkali and salt components, which have poor electrical conductivity when dry, and have a higher electrical conductivity when exposed to water and damp. In bad weather such as rain, snow melting, fog, etc., the insulation strength of polluted insulators is greatly reduced, causing flashover of insulators under normal operating voltage, resulting in large-scale power outages, which are called pollution flashover accidents of lines, and pollution flashover accidents are prevented. The me...
