NOVELTY - A floor coating comprises 35-45 pts. wt. resin, 2-4 pts. wt. graphene, 10-20 pts. wt. quaternary ammonium salt, 10-20 pts. wt. isothiazolinone, 1-3 pts. wt. dispersant, 1-2 pts. wt. leveling agent, 0.5-2.5 pts. wt. defoamer, and 35-50 pts. wt. solvent. USE - Floor coating used for treating and preventing moss (claimed). ADVANTAGE - The coating effectively removes construction surface residual moss and prevents it from regenerating, and has good sterilization function and strong adhesive force. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of floor coating comprising mixing resin, solvent, graphene, dispersant, 50% of leveling agent and defoamer, and stirring to obtain first component; mixing quaternary ammonium salt and isothiazolinone with solvent, stirring, adding remaining 50% of leveling agent and remaining raw materials, and stirring to obtain second component; and mixing two components.
