Preparation method of integrated plastic gravure alcohol-soluble aqueous composite ink resin

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 wide application prospect in the field of plastic gravure composite inks.

[0001] The invention relates to a resin for plastic gravure composite ink, in particular to an integrated plastic gravure alcohol-water composite ink resin and a preparation method thereof. technical background

[0002] In recent years, with the continuous improvement of people's living standards, it not only drives the rapid growth of the packaging industry, but also promotes the continuous development of plastic gravure ink technology and market. At present, plastic gravure ink has been widely used in plastic packaging, such as various plastic film substrate packaging in food, medicine, agricultural and sideline products, daily necessities and other industries, and its application range covers almost all packaging fields. In order to adapt to the pursuit of "green and environmental protection" in social development, plastic gravure ink companies and related research institutions have been committed to the research and development of "green" inks in recent y...
