High abrasion-resistant water-borne finishing coat for container and preparation method thereof

The invention provides a high abrasion-resistant water-borne topcoat for a container. The high abrasion-resistant water-borne finishing coat is prepared from the following components in parts by mass: 20 to 30 parts of water-borne acrylic resin, 10 to 15 parts of fatty isocyanate, 4 to 6 parts of lime powder, 4 to 6 parts of graphite powder, 2 to 3 parts of copper oxide powder, 1 to 3 parts of modified silicon sol, 0.2 to 0.4 part of dispersant, 8 to 14 parts of pigment, 2 to 6 parts of environment-friendly co-solvent, 0.1 to 0.2 part of neutralizing agent, 0.2 to 0.5 part of defoaming agent, 0.4 to 0.6 part of flatting agent, 0.3 to 0.5 part of substrate wetting agent, 0.5 to 1.0 part of thickener and 5 to 10 parts of deionized water. The high abrasion-resistant water-borne finishing coat has the advantages that the content of VOC (voltaic organic chemical) is lower, the drying time of a painting film is short, and the production and environment-friendly requirements are met; by containing abrasion-resistant
