Waterborne acrylic coating as well as preparation method and application thereof

The invention discloses a water-based acrylic coating as well as a preparation method and application thereof, and belongs to the technical field of water-based coatings. The water-based acrylic coating provided by the invention is prepared from the following raw materials in parts by mass: 18 to 32 parts of water-based acrylic resin, 0.5 to 8 parts of pigment, 40 to 65 parts of filler, 5 to 30 parts of water, 0.05 to 0.8 part of thickening agent, 0.3 to 1.5 parts of dispersing agent, 0.3 to 1.5 parts of defoaming agent and 0.8 to 1.8 parts of coalescing agent. The color-to-base ratio of the coating is 4.2 to 5.2. From the three angles of improving the hardness of the coating, constructing a rough surface and reducing the cohesion of the coating, the water-based acrylic coating with a high pigment-base ratio is adopted, so that the hardness of the coating can be effectively improved, the contact area after the coating is tightly attached is reduced, and the surface acting force and the cohesion are reduced, t
