Abstract

The invention discloses an anti-corrosive coating for the surface layer of electrical equipment and a preparation method thereof, and relates to the field of anti-corrosive coatings. The anti-corrosive coating is prepared form the following raw materials in part by weight: 25-35 parts of epoxy resin, 15-25 parts of polyurethane resin, 30-40 parts of polyacrylic resin, 5-10 parts of polydimethylsiloxane, 4-8 parts of dibutyl phthalate, 6-10 parts of mica, 3-6 parts of laterite, 5-10 parts of bentonite, 4-8 parts of talcum powder, 4-8 parts of graphene, 3-6 parts of zinc powder, 3-6 parts of zinc oxide, 3-6 parts of aluminum oxide, 4-8 parts of glass fibers, 3-6 parts of nano titanium dioxide, 3-6 parts of nano silicon carbide, 2-4 parts of microcrystalline wax, 2-4 parts of butyl stearate,10-15 parts of acetone and the like. The coating has the advantages of being good in ductility, capable of being easily applied uniformly, good in cohesiveness, not liable to fall off, and excellent in heat resistance and ageing resistance, a coating layer is not liable to crack, the raw material cost is low, the preparation method is simple, and the operation is easy.

Description

technical field [0001] The invention relates to the field of anti-corrosion coatings, in particular to an anti-corrosion coating for the surface layer of electric equipment and a preparation method thereof. Background technique [0002] Power equipment mainly includes 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, etc. device and so on. Equipment maintenance in power equipment is costly, and part of the maintenance is mainly due to the surface corrosion of power equipment. How to reasonably reduce the corrosion of power equipment, save maintenance costs, and reduce maintenance costs. In the prior art, it is important to spray anti-corrosion paint on the surface of the electric equipment, and the power equipment will generate a lar...
