NOVELTY - An ultra-thin wear-resistant non-stick coating comprises 50-60 pts. wt. silicon carbide porous ceramic foam, 35-45 pts. wt. carborundum, 40-50 pts. wt. polycaprolactone-polycarbonate-graphene copolymer, 20-30 pts. wt. mica powder, 10-15 pts. wt. dispersant, 80-90 pts. wt. PTFE, and 15-20 pts. wt. polyethylene glycol. USE - The ultra-thin wear-resistant non-stick coating is useful for baking mold surface. ADVANTAGE - The ultra-thin wear-resistant non-stick coating adopts special spot coating and PTFE high-durability coating, which increase scratch resistance and corrosion resistance of coating, and uses ceramic material primer layer, which is coated with carborundum and mica powder through self-prepared polycaprolactone-polycarbonate-graphene copolymer, so that the food layer contact surface located on outermost layer has excellent thermal conductivity, concave-convex texture, and wear resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the ultra-thin wear-resistant non-stick coating, which involves: (S1) adding carborundum and mica powder to a planetary ball mill for mixing and ball milling for 1-2 hours; (S2) drying the mixture at 110-130 degrees C, and then heating at 1100-1400 degrees C under a nitrogen atmosphere for 1.5-3 hours; (S3) uniformly mixing the mixed powder obtained in step (S2) with polycaprolactone-polycarbonate-graphene copolymer, dispersant and one-third of polyethylene glycol, and leaving still for 10-20 minutes to obtain a semi-solidified ceramic material primer layer; (S4) mixing silicon carbide porous ceramic foam with one-third of the polyethylene glycol, then coating on the primer layer to form a special spot coating, and drying in dark at room temperature; and (S5) uniformly mixing remaining one-third of polyethylene glycol with PTFE, and coating on the outside of the special spot coating of the dried film obtained in step (S4) to form the coating for the surface of the baking mold, which is ceramic material primer layer, special spot coating, and PTFE high-durability coating from top to bottom, where the primer layer of ceramic material is food-contacting surface.
