Abstract

The invention discloses an anticorrosive coating for electric power equipment and a preparation method thereof, and relates to the coating field, the anticorrosive coating includes the flowing raw materials by weight: 20-26 parts of modified acrylate, 12-18 parts of epoxy resin, 3-7 parts of N-methyl pyrrolidone, 3-7 parts of lauryl alcohol polyoxyethylene ether, 2-6 parts of mica powder, 1.5-2.8parts of zirconium acetate, 3-7 parts of mullite powder, 2-6 parts of lithium bentonite, 2-7 parts of nano-titanium dioxide, 0.8-1.6 parts of lithium amide, 1.2-3.4 parts of diamond, 1-3 parts of molybdenum trioxide, 1.5-3 parts of nano-silicon carbide, 3-6 parts of nano-zinc oxide, 3-6 parts of glass fiber and the like. The coatings has good weatherability and corrosion resistance through the synergistic action of the raw materials, and through compound effect of the diamond and the nano-silicon carbide and other raw materials, the scratch resistance between coatings is enhanced.

Description

technical field [0001] The invention relates to the field of anticorrosion coatings, in particular to an anticorrosion coating for 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 large amount of heat durin...
