NOVELTY - Aqueous floor coating comprises inorganic nano-enhancer 200-235 parts mass, 1.5-2.5 parts mass defoamer, 90-100 parts mass titanium dioxide, 400-450 parts mass filler, 3-4 parts mass cellulose, 1-2 parts mass bactericide, 50-70 parts mass film-forming emulsion and 1-3 parts mass film-forming aids, where the filler comprises kaolin and graphene in a mass ratio of 3:1. USE - Aqueous floor coating. ADVANTAGE - The coating has stable structure, and greatly improves the wear resistance of the coating, and is solvent-free, and ensures improved shelf life of the coating. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the floor coating, involving (a) stirring 1/2 defoamer and cellulose of the total amount of inorganic nano-reinforcing agent and defoamer, and stirring at a speed of 500-800 rpm for 5-10 minutes, (b) adding titanium dioxide and filler to the mixture, and stirring at 1000-3000 rpm for 30-40 minutes, and (c) adding the bactericide, film-forming emulsion, film-forming aid and remainder of defoamer, and stirring for 30-50 minutes to obtain the coating.
