Water-based coating with high-abrasion resistant and environment-friendly functions

The invention relates to the technical field of coatings, in particular to a water-based coating with high-abrasion resistant and environment-friendly functions. The water-based coating adopts the technical scheme that the water-based coating is mainly prepared from 40 parts of water, 20 parts of acrylic emulsion, 0.3 part of defoaming agent, 1 to 2 parts of coffee functional additive, 0.8 part of antibacterial agent, 1 part of dispersant, 2 parts of anti-precipitating agent and 0.9 part of flatting agent, wherein the anti-precipitating agent is prepared from the following components: 3 parts of hydrogenated castor oil and 0.5 to 1 part of sodium chloride; the antibacterial agent is prepared from the following raw materials in parts by mass: 0.5 part of polyurethane, 0.2 part of chitosan and 2 parts of honeysuckle flower extract. The water-based coating has the advantages that the components are reasonable, the cost is low, the compatibility of the components is good, and the environment-friendly property is
