AI Technical Summary

Problems solved by technology

But it also has many deficiencies. For example, it uses mostly small-molecule acrylate. After photocuring, its crosslinking density is relatively large. Although it has good hardness, its toughness is not high, and its high and low temperature resistance is relatively low. Poor enough for daily use

Abstract

The invention discloses an ultraviolet-curable coating. The coating is characterized by being prepared from the following components in parts by weight: 60-80 parts of epoxy acrylic acid, 50-65 partsof an epoxy acrylate diluent, 20-45 parts of tricyclodecane dimethanol diacrylate, 20-30 parts of borosilicate modified epoxy resin, 20-35 parts of tripropylene glycol diacrylate, 60-80 parts of trimethylolpropane triacrylate, 5-15 parts of ethoxylated trimethylolpropane triacrylate, 5-8 parts of 2,4,6(trimethylbenzoyl)diphenylphosphine oxide, 1-3 parts of 1-hydroxy-cyclohexyl-phenyl ketone and 0.5-1.5 parts of triaryl triarylsulfonium hexafluoroantimonate salts. The coating has that follow beneficial effects: (1) resin is cured fast and completely; (2) the viscosity of the resin system is lower; (3) a cured coating film has high hardness, high and low temperature resistance and good toughness.

Description

technical field [0001] The invention relates to a coating, in particular to an ultraviolet curing coating. Background technique [0002] Over the past few years, UV-curable coatings have grown rapidly in fiber optic coatings, CD coatings / DVD adhesives, credit cards, wood, beverage cans, food packaging, magazine covers, medical devices, and the automotive industry . UV-curable coatings have huge market potential, and their proportion in the entire coating products is increasing year by year. UV-curable coatings are mainly composed of oligomers, monomers, photoinitiators and additives. The main reaction process of UV curing is that the photoinitiator is decomposed by radiation to generate active free radicals to initiate the polymerization and crosslinking of monomers / oligomers. [0003] At present, the resins used in UV curing are basically two types: acrylic resin and epoxy resin. Among them, acrylic resin is a resin made by copolymerization of acrylates, methacrylates an...
