NOVELTY - Inorganic low-temperature microcrystalline ceramic coating comprises 30-40 pts. wt. low melting point glass powder, 10-15 pts. wt. curing agent, 8-10 pts. wt. nano-scale titanium dioxide, 6-8 pts. wt. titanium nitride powder, 10-15 pts. wt. nano-alumina, 10-15 pts. wt. nano-silicon oxide, 10-15 pts. wt. nano titanium oxide, 10-15 pts. wt. nano-zirconia, 3-5 pts. wt. graphene, 1-3 pts. wt. wetting and dispersing agent, 1-3 pts. wt. thickening agent and 20-30 pts. wt. water. USE - The inorganic low-temperature microcrystalline ceramic coating is useful for preparing aluminum-based boiler coating (claimed). ADVANTAGE - The coating has properties of enamel materials and does not have the brittleness of enamel materials, the formed coating has good toughness, a temperature resistance of over 600℃, and good antibacterial properties, low expansion, acid and alkali corrosion resistance, high insulation, wear resistance and high hardness, and far infrared function, is a non-toxic, tasteless, non-polluting food-grade coating, has better adhesion and better safety, and does not release harmful substances even when heated at high temperature, can be used as a replacement for Teflon coating, so as to better protect the boiler and improve the service life of the boiler. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing inorganic low-temperature microcrystalline ceramic coating, comprising (i) adding wetting and dispersing agent and low-melting point glass powder into water, and stirring until fully mixed to obtain a mixture, (ii) adding nano-scale titanium dioxide, titanium nitride powder, nano-alumina, nano-silicon oxide, nano-titanium oxide, nano-zirconia and graphene into the mixture, stirring and dispersing to obtain a dispersing, and (iii) adding thickening agent and curing agent into the dispersion and uniformly stirring.
