Anti-ultraviolet wear-resistant curable coating

Abstract

The invention discloses an anti-ultraviolet wear-resistant curable coating which is prepared from the following raw materials in parts by weight: 2.5-4 parts of a photosensitive initiator, 2-3 parts of nano-zirconium oxide, 0.8-1.5 parts of acrylic polyol, 5.6-7.2 parts of carbamate, 4.5-6.6 parts of vinyl acetate maleate, 1.2-1.5 parts of itaconic acid, 0.35-0.78 part of a filler, 0.3-0.5 part of a dispersant and 0.1-0.2 part of a mildew-proof agent. The anti-ultraviolet wear-resistant curable coating disclosed by the invention can obtain an aesthetic and high-performance coated film by performing spraying construction once; in comparison with a traditional way of coating twice or three times, the anti-ultraviolet wear-resistant curable coating has the advantages of high production efficiency, low energy consumption, low cost and the like, the obtained coated film has the characteristics of great appearance, excellent resistance to scratching, wear resistance and solvent resistance and the like; and in addition, a water-based colored coating composition has the advantages of no or a relatively low content of volatile organic compounds and little environmental pollution, and can be used as an environment-friendly material.

Description

technical field [0001] The invention relates to a coating, in particular to a wear-resistant and curable coating capable of preventing ultraviolet rays, and belongs to the field of coatings. Background technique [0002] In the past, most of the coatings used on substrates were solvent-based coatings. However, the volatile organic solvents discharged into the atmosphere by solvent-based coatings have a bad impact on the environment. In recent years, due to human beings' emphasis on environmental protection and energy, countries all over the world have successively strictly controlled the content of VOC in coatings, which has prompted the research on coatings to gradually shift from conventional solvent-based coatings to water-based coatings. Compared with solvent-based coatings, water-based coatings have the advantages of no VOC or low VOC content, and low environmental pollution. The traditional coating on the surface of plastic parts generally requires two coatings and tw...
