Abstract

The invention discloses environment-friendly water-based flexographic printing UV ink. The environment-friendly water-based flexographic printing UV ink is prepared from the following components in percentage by mass: 30-60% of UV-cured water-based blended resin, 4-36% of a photoinitiator, 2-8% of a reactive diluent, 3-10% of deionized water, 1-2% of an organic pigment, 2-3% of a dispersing agent,0.5-1% of an anti-sticking agent, 0.5-1% of an anti-scraping agent and 15-20% of a cosolvent. The UV-cured water-based blended resin is formed by blending polycarbonate-based urethane acrylate and silane-based modified acrylate resin according to a ratio of (0.5-1.2): (2.5-3.5). The photoinitiator is prepared by mixing four compounds including 2-hydroxyl-methylphenylpropane-1-one, 1-hydroxyl-cyclohexyl-phenyl ketone, 2-phenylbenzyl-2-dimethylamino-1-(4-morpholinobenzophenyl)butanone and 2-methyl-1-(4-methylthiophenyl)-2-morpholinyl-1-acetone.

Description

technical field [0001] The invention relates to the technical field of inks, in particular to an environmentally friendly water-based flexographic UV ink. Background technique [0002] In the formulation of flexo printing water-based UV ink, it is necessary to meet the requirements of printability and the performance of packaging, so it is necessary to choose the components of the formulation reasonably. In flexo printing water-based UV inks, the main components include oligomers, photoinitiators, pigments and additives. At present, there have been a large number of new water-based UV inks used in screen printing at home and abroad. The oligomers used in the research of many water-based UV inks are mostly a resin or a copolymer, and active monomers are required. However, active monomers are volatile to a certain extent, which is harmful to the environment and human health. In the selection of oligomers, there are also blends of polyether acrylate and polyurethane acrylate...
