Problems solved by technology

[0004] However, the single-liquid alcohol-water-based composite ink prepared with polyacrylate as the resin binder is mainly suitable for BOPP plastic film substrates and alcohol-soluble laminating adhesives due to the weak polarity of polyacrylate molecules. When used on the surface, the adhesion is poor, and the compatibility with the ester-soluble laminating adhesive is poor, the composite strength is low, and it cannot withstand high-temperature boiling at 98°C; while polyurethane is a single-liquid alcohol prepared by resin binder. Water-based composite ink, due to the strong polarity of polyurethane molecules, is mainly suitable for PET plastic film substrates and ester-soluble laminating adhesives, which have good high temperature resistance; when used on BOPP plastic film substrates, the adhesion is poor , and has poor compatibility with alcohol-soluble laminating adhesive, and the composite strength is low

Abstract

The invention relates to a resin for plastic gravure composite ink, in particular to an integrated plastic gravure alcohol-soluble aqueous composite ink resin and a preparation method thereof. In the preparation method of the integrated plastic gravure alcohol-soluble aqueous composite ink resin for gravure, the integrated plastic alcohol-soluble aqueous composite ink resin is obtained by polymerizing the raw materials of a polymerizable polyurethane macromonomer, (methyl) acrylic ester, vinylacetate and active functional monomer through solution radicals. Due to the introduction of a polyurethane chain, the ink has favorable adhesive force on various plastic film substrates (BOPP (Biaxially-oriented Polypropylene), PET (Polyethylene Terephthalate), PA (Polyamide), PVC (Polyvinyl Chloride), PE (Poly Ethylene), PC (Polycarbonate) and the like), good printing adaptability and high composite strength, adapts to various laminating glues (ester-soluble type, alcohol-soluble type), and can be boiled in water with the high temperature of 98 DEG C. The preparation method of the plastic gravure composite ink resin is simple, the prepared ink has good printing effect and strong adaptability, realizes the integrated adaption of the substrates and the laminating glues, and can be used for printing various plastic substrates; without using crosslinking components, the ink can be boiled in water with the high temperature of 98 DEG C and has the advantages of convenience in operation and high composite strength; the resin has alcohol solubility, economy, environmental protection and wideapplication prospect in the field of plastic gravure composite inks.
