NOVELTY - A graphene aqueous wood lacquer comprises 2-6 pts. wt. graphene, 30-50 pts. wt. heavy calcium carbonate, 10-20 pts. wt. barium sulfate, 30-60 pts. wt. silicone acrylic emulsion, 1-5 pts. wt. alcohol ester, 1-2 pts. wt. regulator, 1-2 pts. wt. bactericide, 10-20 pts. wt. fumed silica, 1-2 pts. wt. 740w wetting dispersant (nonylphenol ethoxylate), 1-2 pts. wt. defoamer, 0.1-0.5 pt. wt. iron oxide yellow, and 30-60 pts. wt. deionized water. USE - Graphene aqueous wood lacquer (claimed). ADVANTAGE - The graphene aqueous wood lacquer has excellent hardness, adhesiveness, dispersibility, film-forming property, crack resistance, and safety, and contains no volatile solvent. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) preparation of wood lacquer, which involves grinding heavy calcium carbonate and barium carbonate to a particle size of 2500 mesh, dispersing the ground material, adding remaining components, stirring for 30 minutes at 1200 rpm, measuring, and packaging; and (2) usage method of wood lacquer, which involves coating a layer of wood primer on wooden furniture, drying, polishing once, wiping the surface, spraying the lacquer using a gun, polishing using 800-mesh fine sand, wiping, and spraying.
