▎ 摘　　要

NOVELTY - Ceramic identification coating comprises binder and ceramic aggregate, where the ceramic aggregate comprises alumina, zirconium silicate and zirconia, the alumina comprises micron-sized alumina and nano-sized alumina, a curing agent comprising zinc oxide and lime, defoamer, 3-aminopropyltriethoxysilane, graphene, N,N-dimethylformamide, and antibacterial agent. USE - As ceramic identification coating. ADVANTAGE - The ceramic identification coating increases the bonding strength of the graphene oxide and the coating matrix, reduces the cracks between the graphene oxide and the coating matrix, effectively improves the corrosion resistance of the coating, and saves energy. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the ceramic identification coating comprising (a) adding nano alumina to the hydrolysis solution of 3-aminopropyltriethoxysilane, and heating it in an oil bath in anhydrous ethanol solution to fully react to obtain silanized nano alumina, (b) adding the silanized nano alumina and graphene oxide to the N,N-dimethylformamide solution, heating the oil bath to fully react, filtering, centrifuging and drying to obtain the nano alumina/graphene oxide hybrid, (c) mixing the nano alumina/graphene oxide hybrid prepared in step (b2) with ceramic aggregate, antibacterial agent and curing agent by ball milling, and mixing and stirring the powder and adhesive evenly, adding defoamer, (d) obtaining the corrosion-resistant ceramic coating by mixing the powder and the adhesive evenly and adding the defoamer is coated on the substrate by means of blade coating, and subjecting the coating to a gradient curing treatment to obtain the required inorganic ceramic coating.
