Abstract

The invention belongs to the field of printing ink and specifically relates to polyacrylic acid printing ink resin and a preparation method thereof. The preparation method comprises the steps of uniformly mixing (methyl) acrylic acid, (methyl) acrylate, a vinyl monomer, an active functional monomer, an auxiliary component, a molecular weight regulator and an initiator in a feeding tank to obtain reaction materials; then, pumping the reaction materials into a tubular reactor in which a static mixing device is arranged, and preparing polyacrylic acid printing ink resin at a high temperature under high pressure by adopting a continuous main body polymerization method, wherein the adopted continuous main body polymerization process effectively inhibits occurrence of gelling and implosion reaction in a main body polymerization process, ensures controllability of molecular weight of the polyacrylic acid printing ink resin, and prepares the polyacrylic acid printing ink resin with number-average molecular weight of 10000-70000. The polyacrylic acid printing ink disclosed by the invention has good solvent release property and printing adaptation.

Description

technical field [0001] The invention belongs to the field of printing ink, in particular to polyacrylic acid ink resin for printing and a preparation method thereof. Background technique [0002] In recent years, with the diversification of packaging requirements and the development of packaging technology, various plastic films have emerged as packaging materials. Plastic films for packaging often require printing for reasons of decoration or surface protection. Plastic gravure ink is a coloring material used for plastic packaging printing. [0003] In recent years, the ester-soluble and alcohol-soluble polyurethane plastic gravure inks that have appeared on the market have problems such as high price and poor wetting and dispersibility of pigments, which have affected the popularization and use of such products. [0004] In view of this, researchers are developing more and more alcohol-soluble acrylic ink resins. For example, Chinese patent CN101747475B discloses a synth...
