NOVELTY - A coating comprises 26-38 pts. wt. silicone epoxy resin polymer, 19-25 pts. wt. polyurethane resin, 27-42 pts. wt. phenolic epoxy resin, 2-8 pts. wt. nano-cerium oxide, 0.3-2.1 pts. wt. graphene, 7-13 pts. wt. calcined kaolin, 12-19 pts. wt. modified zeolite powder, 8-16 pts. wt. rutile titanium dioxide, 5-12 pts. wt. expanded perlite, 7-15 pts. wt. ethylene-tetrafluoroethylene copolymer, 6-16 pts. wt. nano titanium dioxide, 8-15 pts. wt. mica, 2-8 pts. wt. glass beads, 13-22 pts. wt. ammonium tripolyphosphate, 1-5 pts. wt. leveling agent and 40-50 pts. wt. solvent. USE - Coating for use in power distribution cabinet housing (claimed). ADVANTAGE - The heat-resistant and corrosion-resistant coating has high thermal stability and excellent surface adhesion, and improves the safety of power distribution cabinet. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: preparation of coating, which involves (1) weighing each raw material, (2) adding silicone epoxy resin polymer, polyurethane resin and phenolic epoxy resin to a reaction kettle, warming up to 70-80 degrees C, mixing evenly, then adding graphene to the mixture, adding nano-cerium oxide and stirring for 2-3 hours to obtain product (a), (3) adding calcined kaolin, rutile titanium dioxide, expanded perlite, nano titanium dioxide, mica and glass beads, mixing evenly, placing in ball mill and grinding to size of 20-30 mu m to obtain product (b), (4) placing the reaction product (a) and reaction product (b) in reaction kettle, mixing evenly, then adding ethylene-tetrafluoroethylene copolymer, ammonium tripolyphosphate, modified zeolite powder and solvent, mixing evenly, warming up to 40-60 degrees C, insulating for 5-10 minutes and cooling to obtain final product; and #power distribution cabinet housing, which is provided with surface coated with heat-resistant and corrosion-resistant coating.
