Abstract

The invention provides an ultraviolet curing coating raw material and a coating prepared from same. The ultraviolet curing coating raw material comprises the following components in parts by weight: 10-20 parts of six-functional aliphatic polyurethane acrylic resin, 5-10 parts of three-functional aliphatic polyurethane acrylic resin, 10-15 parts of self-initialized ultraviolet curing resin, 2-8 parts of metal effect pigment, 2-15 parts of UV cured crylic acid double-bond celluosic resin, 0.01 part of a polymerization inhibitor, 1-6 parts of adhesion property prompting resin, 5 parts of extinction powder, 2-5 parts of a photoinitiator, 25-60 parts of a diluent and 0.01-0.5 part of an additive, wherein the self-initialized ultraviolet curing resin is DRE-527 purchased in Changxin in Taiwan. Due to addition of acrylic monomers, the reaction speed of the pigment with metallic effects and the acrylic monomers can be increased due to the groups in the acrylic monomers, and due to cross-linking reaction of the UV cured crylic acid double-bond celluosic resin with a double-bond orientation function and the UV resin with double bonds, the cross-linking density of the coating can be improved; due to addition of the polymerization inhibitor, problems such as flocculation and retrogradation can be solved when the coating is stored.

Description

technical field [0001] The invention relates to the field of ultraviolet light curing, in particular to a raw material for ultraviolet light curing paint and the paint made therefrom. Background technique [0002] UV-curable coatings are widely used in home appliances, 3C electronic products, automotive supplies and other fields due to their low energy consumption and high efficiency that other types of coatings do not have. In order to improve the decorative and protective properties of products, metallic color has become one of the most used colors due to its excellent metallic texture. The existing metallic effect coatings are traditional thermoplastic coatings, polyurethane coatings or thermosetting coatings. The required baking The time is longer, the crosslinking density is lower, and the wear resistance and chemical resistance of the product are relatively poor. At the same time, due to the longer baking time, the construction efficiency is lower. [0003] For exampl...
