Abstract

The invention discloses acrylate resin for long-chain alkyl isocyanate modified ink and a preparation method of the acrylate resin. The acrylate resin comprises the following components (in parts by weight): 50-80 parts of mixed monomers A, 20-50 parts of mixed monomers B, 10-30 parts of long-chain alkyl isocyanate, 0.5-2 parts of an initiator, 0.05-1 part of a polymerization inhibitor and 110-130 parts of a solvent. The preparation method comprises the following steps: uniformly mixing the mixed monomers A and the initiator to prepare a component I; mixing the mixed monomers B to prepare a component II; simultaneously and dropwise adding the component I and the component II into a reaction kettle containing the solvent, carrying out a polymerization reaction to obtain hydroxyl-containing acrylic resin, adding the polymerization inhibitor and the long-chain alkyl isocyanate, and carrying out a reaction; and finally, conducting diluting with the solvent to obtain the acrylate resin for the long-chain alkyl isocyanate modified ink. By means of the long-chain alkyl isocyanate, the adhesion fastness of the long-chain alkyl isocyanate on the surface of a plastic film is improved, and particularly, the long-chain alkyl isocyanate has good adhesion performance on a non-treated plastic film; and reaction procedures are greatly reduced, and preparation cost is saved.

Description

technical field [0001] The invention belongs to polymer materials and a preparation method, in particular to an acrylate resin for long-chain alkyl isocyanate modified ink and a preparation method thereof. Background technique [0002] In recent years, with the introduction of various types of high-speed and high-efficiency printing machinery, and the improvement of printing quality requirements in publishing, packaging and other industries, ink resin has become a key factor determining the quality of ink and printed matter, and its role in the ink industry is becoming more and more important. . Acrylic resin, because of its excellent light resistance, thermal stability, solvent resistance, abrasion resistance, low overall cost, and wide range of applicable substrates, the prepared ink is widely used in the printing field with plastic film as the printing substrate. [0003] The ink prepared by using the existing acrylate resin is only suitable for printing on the treated s...
