NOVELTY - A graphene nano-silver antibacterial coating comprises 10-20 pts. wt. water, 0.1-0.5 pt. wt. cellulose, 0.1-0.5 pt. wt. wetting agent, 0.5-2 pts. wt. antifreezing agent, 0.1-0.5 pt. wt. thickener, 0.1-0.5 pt. wt. defoaming agent, 5-15 pts. wt. titanium dioxide slurry, 50-70 pts. wt. filler paste, 0.1-0.5 pt. wt. multifunctional amine additive, 10-20 pts. wt. emulsion, 0.2-1 pt. wt. coalescent, 0.1-0.5 pt. wt. leveling agent, and 0.1-0.5 pt. wt. antibacterial additive. The antibacterial additive comprises graphene and nano-silver in a ratio of 1:50-50:1. USE - Graphene nano-silver antibacterial coating (claimed). ADVANTAGE - The graphene nano-silver antibacterial coating has excellent antibacterial activity, and slow silver ion release function. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene nano-silver antibacterial coating, which involves (i) adding water, cellulose, coalescent, defoaming agent, antibacterial agent, leveling agent, antibacterial aid, and antifreezing agent, mixing and stirring uniformly to obtain mixture (a), (ii) adding titanium dioxide slurry, filler paste, and emulsion to mixture (a), mixing and stirring uniformly to obtain a mixture (b), (iii) adding thickener to mixture (b), mixing, and stirring uniformly.
