b. coating anti-oxidation coatings on two sides of a pretreated steel plate, baking the steel plate in a drying oven at 180-220 ℃ for 15-22s by hot air, coating high-temperature-resistant coatings on two sides of the steel plate after cooling, baking the steel plate in a drying oven at 150-200 ℃ for 10-18s by hot air, and cooling;
c. coating the prepared antistatic color paint on the upper side of the steel plate coated with the high-temperature resistant paint, baking the steel plate in a drying oven at the temperature of 200-250 ℃ for 15-22s by hot air, then feeding the polyvinyl fluoride film and the steel plate coated with the antistatic color paint into the middle of an upper covering roller and a lower covering roller, and attaching the film to the upper side of the steel plate under the action of the pressure of the upper roller and the lower roller and the high temperature;
d. coating primer paint on the lower side of the steel plate covered with the film, baking the steel plate in a drying oven at the temperature of 200-250 ℃ for 15-22s by hot air, and cooling to prepare the antistatic wear-resistant color-coated steel plate.
