Abstract

The invention discloses high-hardness ultraviolet-cured wood paint. Raw materials of the high-hardness ultraviolet-cured wood paint comprise, in parts by weight, 20-35 parts of epoxy acrylate, 15-28 parts of urethane acrylate, 15-26 parts of phenyl glycidyl ether acrylate, 3-9 parts of reactive diluent, 0.5-1.2 parts of photoinitiator, 3-15 parts of epoxy resin, 3-8.5 parts of alicyclic amine, 3-10 parts of epoxy curing agent, 3-8 parts of modified graphene oxide, 1-2 parts of nano-silica, 0.5-1.6 parts of montmorillonoid, 0.3-2 parts of pyrene-1-butyric acid, 1-3 parts of silane coupling agent KH-580, 2-5 parts of 3,9-diethyl-3,9-dihydroxytoluene-1,5,7,11-tetraoxaspiro-5,5-undecane and 0.1-1 part of assistant. The high-hardness ultraviolet-cured wood paint has high adhesion to a wood basematerial, good hardness and water resistance and excellent heat-resistant performance.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a high-hardness ultraviolet light curing wood coating. Background technique [0002] Wood coatings are mainly used for decoration and protection on the surface of wood products. UV-curable coatings are usually composed of prepolymers, diluents, and photoinitiators. They have the characteristics of convenient coating, fast curing speed, and less pollution. They have been widely used as wood coatings. However, when UV-curable coatings are used on wood surfaces, there are many shortcomings, such as low hardness of the cured film, poor water resistance, poor heat resistance, etc., which limit its application in wood coatings. Therefore, UV-curable wood coatings need to be modified to improve their hardness, water resistance and heat resistance. Contents of the invention [0003] Based on the technical problems in the background technology, the present invention proposes a high-h...
