▎ 摘  要

NOVELTY - A graphene glass thermal coating comprises 32-60 pts. wt. binder, 2-20 pts. wt. graphene, 15-55 pts. wt. filler, 5-20 pts. wt. cosolvent, 3-8 pts. wt. additives and 5-40 pts. wt. deionized water. The binder is selected from aqueous epoxy resin, aqueous acrylic acid resin, aqueous polyester resin, aqueous amine curing agent, aqueous amino resin and/or aqueous isocyanate. The graphene is graphene paste with a thickness of less than 20 nm, a film diameter of 3-8 mu m, a specific surface area of 80-200 m2/g, and layer number of less than 10 layers. The filler is selected from ultrafine alumina and/or boron nitride. The cosolvent is selected from anhydrous ethanol, ethylene glycol, alcohol ester, propylene glycol butyl ether and/or propylene glycol phenyl ether. The additive is selected from dispersant, defoamer, substrate wetting agent, leveling agent, anti-sinking agent, thickener and/or coupling agent. USE - Graphene glass thermal coating. ADVANTAGE - The graphene glass thermal coating quickly provides uniform temperature on the outer surface of the glass, ensures heat dissipation effect, so as to prevent the glass from cracking due to uneven heating, ensures safe use of glass during local heating, and rapidly transfers heat away and lowers the temperature of the glass, due to high thermal emissivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene glass thermal coating, which involves (1) uniformly dispersing graphene and filler, grinding to prepare composite thermal conductive functional slurry with fineness of less than 5 mu m, (2) adding composite thermal conductive functional slurry, binder, additives, solvents and deionized water, mixing and dispersing uniformly to obtain final product.
