High-temperature resistant and long-lasting non-stick ceramic coating and preparation method thereof

Abstract

Disclosed is a high-temperature resistant and long-lasting non-stick ceramic coating and a preparation method thereof. The coating includes a primer and a top coating, based on a total weight of the primer being 100%, the primer comprises: silica sol: 26-28%, 1% NaOH solution: 4-5%, pigment: 10-12%, filler: 8-10%, dispersant: 1-1.5%, silane: 28-30%, isopropanol: 3-3.5%, silicone oil microcapsule: 3-4%, 25% formic acid solution: 0.7-1%, the balance being deionized water; based on a total weight of the top coating being 100%, the top coating comprises: silica sol+silane: 82-85%, silicone oil microcapsule: 6-8%, leveling agent: 1-1.5%, 25% formic acid solution: added until a pH value of the top coating is the same as that of the primer, the balance being isopropanol. The ceramic coating has an inorganic structure in its main molecular chain, which features high-temperature resistance, high hardness, and good wear resistance in addition to the long-lasting non-stick property.
