Abstract

The invention discloses an anti-aging coating for a power device and a preparation method thereof and relates to the technical field of coatings. The anti-aging coating is prepared from 55-65 parts of polyamide resin, 55-60 parts of organic silicone modified epoxy resin, 20-25 parts of thermoplastic expansion hollow microspheres, 18-20 parts of hydrophobic gas-phase silica, 15-17 parts of nano titanium dioxide, 13-15 parts of aluminum nitride, 13-15 parts of talcum powder, 20-25 parts of additive and 55-65 parts of water. The anti-aging coating has abrasion-resisting, waterproof, anti-aging, acid and alkali resistance properties, the preparation method is simple, the power device is effectively protected, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an anti-aging coating for electric equipment and a preparation method thereof. Background technique [0002] Power equipment mainly includes two categories: power generation equipment and power supply equipment. Power generation equipment is mainly power plant boilers, steam turbines, gas turbines, water turbines, generators, transformers, etc. Power supply equipment is mainly transmission lines of various voltage levels, transformers, contactors and more. [0003] With the development of industry, on the outdoor box of the power grid, the anti-corrosion, wear-resistant, and acid-alkali resistance functions played by anti-corrosion coatings as the main coating are becoming more and more important. At present, common anti-corrosion coatings are easily corroded and aging , nor can it play a role in self-cleaning and acid and alkali resistance. Contents of the invention [0004...
