Water-based high-temperature-resistant insulating battery paint as well as preparation method and application thereof

The invention relates to the technical field of water-based paint preparation, and discloses water-based high-temperature-resistant insulation battery paint and a preparation method and application thereof.The preparation method of the water-based high-temperature-resistant insulation battery paint comprises the following steps that water-based epoxy resin, a silane coupling agent and water are mixed; sequentially adding magnesium hydroxide, ammonia water, a first defoaming agent and a dispersing agent, and reacting to obtain a mixed solution; and mixing the mixed solution, whisker silicon, glass powder, copper chromite black, bentonite, wollastonite, a flash rust inhibitor, a second defoaming agent and an anti-settling agent for reaction, and adding silica sol after the reaction to obtain the water-based high-temperature-resistant insulating battery paint. The water-based high-temperature-resistant insulating battery paint disclosed by the invention has excellent insulating property, fire resistance, cold an
