NOVELTY - Paint film of water-based floor paint comprises evenly and orderly arranged graphene sheets in paint film structure to form a graphene layer, the graphene layer is in the paint film structure, the thickness direction of the graphene layer is the same as or similar to the thickness direction of the paint film structure. USE - Used as Paint film of water-based floor paint. ADVANTAGE - The paint: is environment-friendly, has very low VOC, has good adhesion, corrosion resistance, water resistance and chemical resistance, simple preparation process, strong controllability. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) water-based floor paint comprising 0.01-5 pts. wt. graphene, 20-35 pts. wt. curing agent, 20-60 pts. wt. pigment and filler, 1-4.65 pts. wt. auxiliary agent, 0.3-1.5 pts. wt. rheology-modified wax emulsion, and 20-30 pts. wt. water as first component, and 20-40 pts. wt. epoxy resin E51, and 0-5 pts. wt. propylene glycol methyl ether acetate as second component; and (2) preparing water-based floor paint comprising preparation of first component: (1) adding and mixing initial mixing of water, curing agent, some additives and rheologically modified wax emulsion, graphene again to obtain a mixture, (2) adding pigments and fillers to obtained mixture to dispersing and grinding and mixing to obtain a mixed slurry, and (3) adding remaining additives to obtained mixed slurry and mixing to obtain first component, and preparation of second component: stirring and mixing epoxy resin E51 and propylene glycol methyl ether acetate and allowing to stand to obtain second component, the water-based floor paint includes first component and second component, and the auxiliary agent includes a dispersant, a wetting and/or leveling agent, an antifoaming agent, and a rheological auxiliary agent.
