Abstract

The invention discloses a UV cured roller coating embellishing clear finish coating which relates to the chemical engineering field, and aims to solve problems of bad adhesion force and difficult embellishing of general UV embellishing finishes. The UV cured roller coating embellishing clear finish coating comprises, by weight, 35-50 parts of an epoxy acrylate, a polyester acrylate or a mixture of the epoxy acrylate and the polyester acrylate, 30-42 parts of an active diluent, 0.2-0.5 parts of a defoamer, 0.5-1 part of a functional assistant, 0.1-0.3 parts of a leveling agent, 8-13 parts of a filler and 9-12 parts of a photoinitiator. The coating has the advantages of good drying performance, good adhesion force, simple one-time UV embellishing, and strong maneuverability.

Description

technical field [0001] The invention relates to an ultraviolet light curing coating in the chemical industry, in particular to an ultraviolet light curing roller coating color correction clear topcoat coating. Background technique [0002] With the continuous development of the furniture market and the change of consumption concept, people have higher and higher requirements for color. The general furniture factory process is to first roll or wipe the base color, then do the clear primer, polish and then repair the color, and finally roll the clear top coat. Through market research, the furniture factory wants to do UV-cured surface color correction at one time, that is, regardless of the color of the primer, it only needs to be applied with a roller. However, there is currently no UV-curable color-retouching topcoat on the market that can meet the requirements. The existing UV-curable color-retouching topcoat has poor adhesion and is not easy to dry. Contents of the inve...
