Abstract

The invention relates to the technical field of coatings, in particular to an ultraviolet curable water-based coating and its preparation method and application. The ultraviolet curable water-based paint comprises the following parts by weight of raw materials: water-based silver plating paste and water-based UV varnish; -2 parts, 35-45 parts of deionized water; the weight ratio of the water-based silver electroplating paste and water-based UV varnish is 1:1.4-1.6. The ultraviolet curable water-based paint of the present invention has better wear resistance, corrosion resistance and high and low temperature impact resistance, can meet the requirements of automatic line spraying, has the characteristics of good adhesion, good appearance and low VOC emissions, and can reduce Pollution to the environment, suitable for mass production applications.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an ultraviolet curable water-based coating and its preparation method and application. Background technique [0002] In the fields of alcohol, cosmetics, 3C and other consumer goods or electronic products, many high-end products usually need to use various special coatings and coating processes to make their inner and outer packaging not only more beautiful, but also to give them outer film protection, Special requirements such as chemical aging resistance and stain resistance, and the national ecological and environmental protection department's control of corporate VOC emission indicators are becoming more and more stringent. However, the existing coatings often have problems such as wear resistance, corrosion resistance, high and low temperature impact resistance, etc., and cannot meet market demand and environmental protection requirements. Contents of the invention [00...
