Abstract

The invention discloses water-based paint for electrical equipment and a preparation method thereof. The water-based paint is prepared from, by weight, 25-40 parts of an organosilicone modification acrylate emulsion, 20-30 parts of phenolic resin, 15-26 parts of ammonium polyphosphate, 10-15 parts of zinc borate, 5-10 parts of pentaerythritol, 10-20 parts of kieselguhr, 7-15 parts of expanded perlite, 0.1-0.3 part of gamma-Al2O3, 5-10 parts of oxidized graphene, 1-2 parts of a film forming agent, 0.01-0.03 part of a defoaming agent and 40-50 parts of water. The water-based paint is short in drying time, good in adhesion, and resistant to fire, high temperature, water and corrosion.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a water-based coating for electric equipment and a preparation method thereof. Background technique [0002] Steel materials are commonly used in the production of power equipment. Steel materials have high strength, good stability, good flexibility, and are easy to process and manufacture. However, corrosion problems are prone to occur on the surface of steel materials, which brings huge losses to the national economy. Coating a water-based paint with less environmental pollution, however, these water-based paints have poor high temperature resistance, and are prone to delamination, peeling, bubbling or cracking when the equipment is running for a long time, and the service life is short. [0003] The Chinese patent application with the publication number CN108641551A discloses a high temperature resistant fireproof coating and its preparation method. The high tempe...
