NOVELTY - Water-based paint comprises anti-tarnishing agent containing aqueous tannic acid inhibitor, aqueous graphene slurry and an anti-yellow resin, where the mass ratio of the aqueous tannic acid inhibitor to anti-yellow resin 0.8-1.2:0.8-1.2. The aqueous graphene slurry comprises graphene oxide, aqueous nanocolloid silicon and a titanate coupling agent a mass ratio of 4-6:3-5:0.8-1.2. USE - Water-based paint. ADVANTAGE - The water-based paint is prepared in an eco-friendly manner. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing water-based paint, which involves: (A) putting antifoaming agent, anti-tarnishing agent, dispersing agent and deionized water in a mixer for uniformly dispersing; (B) heating mixture in a microwave oven to 40-60 degrees C;; (C) adding aqueous graphene slurry, and then stirring at 800-1500 revolutions per minute in presence vacuum for 10-30 minutes; (D) reducing the rotation speed of the mixer to 200-600 revolutions per minute, and then adding aqueous resin dispersion, film-forming auxiliary agent and antifoaming agent into the mixer, and vacuuming for 20-40 minutes; and (E) adding deionized water to dilute, and slowly adding thickener under stirring for 20-40 minutes to obtain water-based paint.
