Problems solved by technology

[0002] UV-curable coatings have attracted more and more attention because of their good environmental protection, but traditional photo-curable coatings generally cannot avoid the use of organic volatiles that are irritating to the human body, so the existing UV-curable coatings have used water To replace irritating organic diluents, UV-curable water-based coatings have attracted the attention of researchers, but the existing UV-curable coatings still have the disadvantages of long curing time and poor stability.

Abstract

The invention discloses ultraviolet light polymerization water-based paint universal for metal and non-metal and a preparation method of the paint. The ultraviolet light polymerization water-based paint universal for metal and non-metal comprises the following raw materials in parts by mass: 60-70 parts of vinyl ester resin, 38-46 parts of urethane acrylate, 1-2 parts of 2-hydroxy-2-methyl-1-phenylacetone, 0.5-1 part of bimercaptoacetic acid isooctyl di-n-octyltin, 35-40 parts of ethanol and 150-180 parts of water. The paint is short in curing time, that is, the curing time is 3 minutes and the adhesion capability to a substrate is of 1 grade, is good in stability and free of layering after being preserved for 6 months. The paint is simple in preparation method and applicable to popularization and application in a wide range.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to a metal and non-metal universal UV-curable water-based coating and a preparation method thereof. Background technique [0002] UV-curable coatings have attracted more and more attention because of their good environmental protection, but traditional photo-curable coatings generally cannot avoid the use of organic volatiles that are irritating to the human body, so the existing UV-curable coatings have used water To replace irritating organic diluents, UV-curable water-based coatings have attracted the attention of researchers, but the existing UV-curable coatings still have the disadvantages of long curing time and poor stability. [0003] To sum up, how to overcome the deficiencies of the prior art has become an urgent problem to be solved in the field of coatings. Contents of the invention [0004] The purpose of the present invention is to overcome the deficiencies of th...
