Abstract

The invention discloses a water-based UV plastic coating as well as a preparation method and an application thereof. The water-based UV plastic coating comprises the following components in parts by weight: 80 parts of urethane acrylate oligomer, 0.2-6 parts of a photoinitiator, 0.2-2 parts of a water-based defoaming agent, 0.5-1 part of a water-based wetting agent, 0.5-1.5 parts of a thickening agent, 0.5-1 part of a water-based flatting agent and 1-18 parts of water. The molecular weight of the urethane acrylate oligomer is 500 to 2800. The water-based UV plastic coating has both hardness and flexibility, has excellent wear resistance and chemical resistance, and can be used as a coating for spraying plastic shells of electronic and electrical products.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a water-based UV plastic coating and a preparation method and application thereof. Background technique [0002] In recent years, UV-curable coatings, referred to as UV coatings, have been widely used in many fields such as 3C, household appliances, automobiles, office supplies, and medical equipment. At present, UV coatings are mainly solvent-based UV coatings, but the disadvantages of solvent-based coatings are obvious, such as high VOC emissions and serious environmental pollution. With the improvement of people's quality of life, water-based UV coatings with high performance and low VOC content have broad application prospects. [0003] Compared with other low-pollution coatings, water-based UV coatings have better product performance, fast curing speed, high construction efficiency, and are suitable for high-speed automatic production. According to statistics, in recent years, the ...
