Abstract

The invention discloses waterborne UV epoxy acrylic resin. The formula comprises the following components (by weight): 250-290 parts of epoxy resin, 40-70 parts of acrylic acid, 60-80 parts of diacidand/or polybasic acid, 0.1-1.5 parts of 4-methoxyphenol, 0.5-3 parts of N,N-dimethyl benzylamine, 80-130 parts of ethanol, 20-80 parts of N, N-dimethylethanolamine, and 200-400 parts of water. With the introduction of itaconic acid for modification of epoxy acrylate, the waterborne UV epoxy acrylic resin has good stability and good hydrophilicity, will not be hydrolyzed or layered after long-termstorage, has fast UV curing rate, and has good adhesion to a base material. The product is convenient and environmentally-friendly to use, and is pollution-free.

Description

technical field [0001] The invention belongs to the field of polymer material synthesis and processing, and in particular relates to a water-based UV epoxy acrylic resin and a preparation method thereof. Background technique [0002] As a new type, environmental protection and energy-saving resin, water-based UV curing resin has better performance than traditional UV curing resin. It can be applied to paper varnish, screen printing ink, lithographic printing ink, plastic varnish, cover It can also be used in photopolymer printing plates, gravure inks and flexo printing inks in terms of varnishes and leather coatings, and even has high application value in wood and wood finishing. Water-based UV curable resin is a safe and environmentally friendly new "green resin" that has developed rapidly in recent years, and has a good application prospect on absorbent substrates. However, in order to ensure the complete evaporation of water, the coating made of water-based UV curable re...
