Problems solved by technology

[0002] Water-based paints are widely used because of their advantages of environmental protection and little harm to the human body. Water-based wood paints with acrylic acid as the main component have good adhesion, will not deepen the color of wood, and are cheap, so they have a large market; However, its wear resistance and hardness are low. Adding polyurethane water-based paint can improve its wear resistance, but the paint film of polyurethane water-based paint has poor water resistance

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-resistant and wear-resistant polyurethane-acrylate water-based coating. Background technique [0002] Water-based paints are widely used because of their advantages of environmental protection and little harm to the human body. Water-based wood paints with acrylic acid as the main component have good adhesion, will not deepen the color of wood, and are cheap, so they have a large market; However, its wear resistance and hardness are low. Adding polyurethane water-based coatings can improve its abrasion resistance, but the paint film of polyurethane water-based coatings has poor water resistance. Contents of the invention [0003] Based on the technical problems in the background technology, the present invention proposes a water-resistant and wear-resistant polyurethane-acrylate water-based coating, which has good water resistance, wear resistance and mechanical proper...
