▎ 摘　　要

NOVELTY - Aqueous coating comprises 50-70 wt.% water-based emulsion type fluorocarbon resin, 5-15 wt.% graphene dispersion, 0.5-2 wt.% dispersant, 0.05-0.2% antifoaming agent, 15-25 wt.% titanium dioxide, 3-15% film-forming aids, 0.05-2 wt.% thickener and 0-20 wt.% water. USE - The aqueous coating or method is useful in the surface of outdoor building base material (claimed). ADVANTAGE - The coating has excellent crack resistance, durability, easy construction, clean and long-termexcellent light-keeping, color-keeping performance, and each component is an environment-friendly component, less than or equal to 75 % relative humidity, temperature is 0 to -50 degrees C and drying for 24-48 hours to form the coating. DETAILED DESCRIPTION - INDEPENDENT CLAIM are also included for: (1) preparation water-based paint comprising taking raw materials , mixing the water-based emulsion type fluorocarbon resin and the graphene dispersion liquid, defoamer, the titanium dioxide, the film forming aid, the thickener, and the water to obtain the water-based paint; and (2) use method comprising coating aqueous coating on the surface of the outdoor building base material
