Abstract

The invention provides a varnish for tin plate ink. The varnish is composed of the following components in percentage by mass: 10-30% of epoxy acrylic resin, 10-20% of polyurethane acrylic resin, 0-10% of polyester acrylic resin, 40-60% of acrylate monomer, 4-10% of photoinitiator, 0.01-0.5% of leveling agent, 0.01-0.5% of defoaming agent, 0.1-2% of wax and 0.5-2% of wear-resistant aid. The invention also provides a preparation method of the varnish for tin plate ink. The varnish provided by the invention has the characteristics of no solvent discharge, low energy consumption, short curing cycle, favorable solvent resistance, favorable adhesive force, favorable processibility and high glossiness, and is especially applicable to tin plate ink. The varnish provided by the invention has no solvent addition, and has the advantage of environment friendliness.

Description

technical field [0001] The invention belongs to the field of chemical industry, and relates to a photocurable varnish, in particular to a varnish used for iron printing ink. Background technique [0002] Iron printing ink varnish is developed to improve the protection of iron printing ink patterns and the beauty of the product. The traditional method is to use solvent-based two-component or multi-component varnish, which is produced by high-temperature thermal baking and curing mode. It has good adhesion and processability, but there are solvent emissions, high energy consumption, long production cycle, and poor chemical resistance of the product. Easy to be eroded by solvents, low gloss and other problems. With the country's emphasis on environmental protection, traditional varnish gradually cannot meet the requirements. Contents of the invention [0003] The purpose of the present invention is to provide a kind of varnish used on iron printing ink, and the described va...
