NOVELTY - A floor paint comprises 60-75 pts. wt. polyurethane resin, 8-11 pts. wt. modified graphene, 7-11 pts. wt. hydroxyethyl cellulose, 15-20 pts. wt. dimethylaminoethyl acrylate, 5-9 pts. wt. nano zinc oxide, 9-17 pts. wt. nano silica, 15-26 pts. wt. curing agent, 0.5-1.5 pts. wt. dispersant, 0.9-1.8 pts. wt. leveling agent, 0.4-0.8 pt. wt. defoamer, 3-5 pts. wt. reactive diluent, 30-60 pts. wt. pigment filler, and 15-30 pts. wt. water. USE - Floor paint. ADVANTAGE - The floor paint has excellent wear resistance and mechanical property, can be prepared by a simple method, and is environmentally-friendly and safe. DETAILED DESCRIPTION - The modified graphene is prepared by preparing graphene oxide by Hummers method, dispersing in a mixed solution of polyethylene glycol and N,N-dimethylformamide, stirring at 300-350 rpm, heating at 80-90 degrees C for 20-30 minutes, inletting nitrogen, adding polyvinylpyrrolidone and tetraethylammonium bromide, heating to 150-160 degrees C, stirring at 300-350 rpm, refluxing for 110-150 minutes, adding carbazole and hydrazine hydrate, cooling to 60-80 degrees C, stirring at 400-500 rpm, sealing, reacting for 2-2.5 hours, filtering, cooling, washing, and drying. An INDEPENDENT CLAIM is included for preparation of floor paint.
