▎ 摘　　要

NOVELTY - Grinding sand aqueous emulsion paint comprises primer and paint finish, where primer comprises 130-150 pts. wt. one-component aqueous polyurethane emulsion, 140-160 pts. wt. acrylic emulsion, 2-4 pts. wt. defoaming agent, 1-3 pts. wt. propylene glycol, 15-30 pts. wt. titanium dioxide particles and 8-10 pts. wt. graphene oxide. The particle size distribution range of the titanium dioxide particles is 300-500 μm, and particle size distribution range of the graphene oxide is 60-100 μm. The paint paint comprises 150-200 pts. wt. acrylic emulsion, 10-12 pts. wt. organic bentonite, 2-4 pts. wt. defoaming agent and 1-3 pts. wt. propylene glycol. The particle size distribution range of the organic bentonite is 600-800 nm, and when in use, the surface of the substrate is coated with the primer, and surface of the primer is dried and then coated with the finish. USE - Grinding sand aqueous emulsion paint used in building paint. ADVANTAGE - The grinding sand aqueous emulsion paint has excellent elastic performance, good bearing function, under the action of dry shrinking stress of the surface paint, and primer is compressed or stretched so that the product is dried. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method use of grinding sand aqueous emulsion paint, which involves: (1) cleaning the base layer, applying primer on the surface of the base layer, and controlling the use amount of the primer to be 0.1-0.15kg/m2, under the condition of room temperature, after the primer is naturally dried to be surface-dried, applying paint finish on the surface of the primer, and controlling the dosage of the finish paint to be 0.05-0.08kg/m2; and (2) finishing the application of the finish paint, naturally drying to finish the application of the product.
