摘要（英）：

The present invention discloses a high temperature resistant coating for transformers, and belongs-the technical field of coatings. The coating comprises, by weight, 80-90 parts of vinyl ester resin, 7-12 parts of zinc phosphate, 12-14 parts of titanium dioxide, 15-18 parts of aluminum triphosphate, 6-9 parts of graphite, 24-30 parts of white corundum fine powder, 30-40 parts of white corundum ultrafine powder, 10-15 parts of brown corundum fine powder, 15-20 parts of brown corundum ultrafine powder, 3-5 parts of boron powder, 6-8 parts of zirconium oxide, 1-2 parts of a dispersant, 3-5 parts of a leveling agent and 0.5-1 part of an anti-settling agent. The invention also discloses a preparation method of the high temperature resistant coating. The high temperature resistant coating has the advantages of effective resistance to a high temperature, good adhesion, difficulty in shedding and dry cracking, and high antirust ability.
