NOVELTY - Gypsum-based fire-retardant fire-retardant paint comprises 70-90 pts. wt. gypsum powder, 2-20 pts. wt. cellulose, 1-5 pts. wt. polystyrene, 1-10 pts. wt. calcium carbonate, 1-5 pts. wt. blowing agent, 1-3 pts. wt. retarder, and 0.1-1 pts. wt. graphene. USE - Gypsum-based fire-retardant fire-retardant paint. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing gypsum-based flame-retardant fireproof coating, which involves: (A) stirring gypsum powder, calcium carbonate, polystyrene, foaming agent and retarder at 1000-1200 rpm for 10-30 min, and mixing uniformly; and (B) adding corresponding weight of cellulose, stirring graphene at 2000-4000 rev/min for 20-30 minutes, and mix to develop fineness to 70-80 micrometer to obtain final product.
