Abstract

The invention belongs to the field of chemical industry, and particularly discloses white finish coat photocurable UV (ultraviolet) paint and a preparation method thereof. The photocurable UV paint comprises the following components in percentage by weight: 20-60% of epoxy acrylate, 20-60% of polyurethane acrylate, 2-5% of phenyl acetone photoinitiator, 0.2-1% of diphenyl phosphine oxide photoinitiator, 0.2-1% of dispersant, 0.2-1% of leveling agent, 1-40% of titanium white TiO2, 5-15% of two-functional-group reactive diluent and 5-30% of three-functional-group reactive diluent. The paint has the characteristics of favorable gloss, adhesive force and leveling property, thus ensuring that the white UV paint can be better applied.

Description

technical field [0001] The invention relates to the technical field of chemical engineering, more specifically, the invention relates to a white top coat photocurable UV coating and a preparation method thereof. Background technique [0002] Light-curing UV coating products can be applied to the surface of various substrates: paper, wood, stone, leather, ceramics, metal, glass, plastic, concrete, etc., especially for some heat-sensitive materials. Photocuring technology is a high-efficiency, environmental, energy-saving, and high-quality material surface treatment technology. It uses ultraviolet light to trigger rapid polymerization and crosslinking of chemically active liquid materials, and instantly solidifies into solid materials. It basically does not contain volatile solvents (VOC ), so it will not cause air pollution, harm to human body and fire hazard. Photocuring only requires radiation energy for photoinitiators, unlike thermal curing or volatile coatings that have...
