NOVELTY - Mildew-proof and damp-proof gypsum-based graphene coating comprises 5-10 pts. wt. modified graphene powder, 300-500 pts. wt. dihydrate gypsum, 100-150 pts. wt. slaked lime, 15-20 pts. wt. mildew inhibitor, 200-250 pts. wt. calcified bentonite, 40-50 pts. wt. sodium bicarbonate, and 10-20 pts. wt. water glass. USE - Mildew-proof and damp-proof gypsum-based graphene coating. ADVANTAGE - The gypsum-based graphene coating has high strength, high toughness, good water resistance, mildew-proof and damp-proof. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing mildew-proof and damp-proof gypsum-based graphene coating, which involves at room temperature, putting dihydrate gypsum into the grinder, then adding sodium bicarbonate and slaked lime, fully mechanically grind and stir for 20 minutes, fully mechanical grinding and stirring for 20 minutes, at 150℃ and 0.3MPa, transferring the material to a ball mill, ball milling modified graphene powder and a certain amount of water, and grinding for 20-30 minutes, in the ball mill, continuing adding calcified bentonite, fungicide, water glass and a certain amount of water at 150℃, at normal pressure, selectively adding coagulant, ball milling for 20-30 minutes, drying the gypsum-based graphene coating colloid obtained into powder at 150℃ and sieving and packaging.
