Problems solved by technology

[0002] The anti-corrosion, wear-resistant, and acid-alkali resistance functions of anti-corrosion coatings as the main coating are becoming more and more important. At present, common anti-corrosion coatings are easy to be corroded and aged, and cannot play the role of self-cleaning and acid-alkali resistance; insulators Corrosion will significantly reduce the mechanical properties of metal materials, destroy the physical structure of insulators, increase the wear and use risks of insulators, greatly shorten the service life of insulators, and pose potential safety hazards. Among the many anti-corrosion strategies, the simplest, most effective, and cost-effective The highest method is to use anti-corrosion coatings for protection; therefore, these insulators are coated with anti-corrosion and wear-resistant coatings, which not only play the role of anti-corrosion on the surface of insulators, but also prolong the coating protection period

Abstract

The invention discloses a preparation method of a corrosion preventing and self-cleaning hydrophobic coating of an insulator. The corrosion preventing and self-cleaning hydrophobic coating is mainly prepared by mixing the following raw materials: 60-80 parts of acrylic resin, 20-30 parts of styrene-butadiene rubber latex, 25-32 parts of nanosilicon dioxide, 18-22 parts of nano aluminum oxide, 7-11parts of a coupling agent, 2-4 parts of methyl methacrylate, 4-6 parts of tributyl citrate, 3-5 parts of polyethylene wax powder and 45-60 parts of N-dimethylformamide. The self-cleaning hydrophobiccoating is high in adhesion, high in abrasion resistance and high in corrosion preventing performance, and meanwhile, the fillers, namely, nanosilicon dioxide and nano aluminum oxide, are modified, sothat the abrasion resistance, the corrosion resistance and the acid-base resistance of the coating are improved, and moreover, the coating is high in hydrophobic performance, and as a result, the insulator can be effectively protected, and the service life of the insulator is prolonged; the pollution flashover fault of a power transmission circuit is solved.
