Abstract

The invention belongs to the technical field of coating preparation, and particularly relates to a photocureable coating as well as a preparation method and application thereof. The coating comprises the following raw materials in parts by weight: 5-20 parts of hyperbranched polyglycerol fatty acid ester, 10-50 parts of polyurethane acrylate, 10-50 parts of a reactive diluent, 0.5-8 parts of a photoinitiator and 0.1-2 parts of an auxiliary agent. When the hydrophilicity of the coating is improved, corrosive groups such as sulfonic acid and carboxylic acid do not need to be introduced, the hyperbranched polyglycerol fatty acid ester contains a large number of ether bonds and has good flexibility, and the hydrophilicity, the adhesive force and the bending resistance of the coating can be improved through the synergistic effect of the hyperbranched polyglycerol fatty acid ester and the polyurethane acrylate. The hyperbranched polyglycerol fatty acid ester with the saponification value of 50-300mg / g improves the hydrophilic effect of the coating on the premise of not influencing other properties of the coating.

Description

technical field

[0001] The invention belongs to the technical field of paint preparation, and in particular relates to a light-cured paint and its preparation method and application. Background technique

[0002] Due to its high efficiency, energy saving, economy and environmental friendliness, UV-curable coatings have received more and more attention in recent years, and have been used in wood, ink, plastic, adhesives, electronic component packaging materials, food packaging, magazine covers, It has been widely used in fields such as medical equipment and automobile industry. UV-curable coatings are mainly composed of oligomers, reactive diluents, photoinitiators and additives. The main reaction process of UV curing is the decomposition of photoinitiator caused by radiation, generating active free radicals and further initiating the polymerization reaction and crosslinking of reactive diluent / oligomer.

[0003] With the continuous development of the national economy and t...
