Then add the weighed ethanolamine slowly for about 20-30 minutes to carry out the amination reaction, control the temperature 9.0; the amination reaction is about 2 hours, during which the pH value of the solution is constantly checked until the solution The pH value of the resin is stable at 8.5~9.0, and the resin is completely aminated and dissolved. Add the defoamer and stir for 10 minutes, and then it can be filtered and put into a co...

Abstract

A water plastic-film intaglio printing ink consists of alkali soluble acrylic copolymer, low-Tg value acrylate copolymer emulsion, high-Tg value acrylate copolymer emulsion, silicon modified acrylate copolymer emulsion as grinding dispersing medium and filming medium. Adhesion modifier, interface modifier and other various accessories are added into ink and the ink can be produced proportionally for red ink, yellow ink, blue ink, black ink and other-color inks. It has bright color, better saturation degree, alkali-resistance and dispersion.

Description

technical field [0001] The invention relates to a water-based gravure ink suitable for use in acrylate copolymer emulsions in the field of IPC classification CO9D and CO9F, in particular to a plastic film water-based gravure printing ink. Background technique [0002] Ink is currently the largest source of pollution in the printing industry. The annual output of ink in the world has reached about 3.5 million tons, and the annual emission of volatile organic compounds (VOC) pollution caused by ink has reached more than 500,000 tons. These organic volatiles include alkanes, aromatic hydrocarbons, alcohols, ketones, ethers and other organic solvents, which can form a more serious greenhouse effect than carbon dioxide, seriously pollute the atmospheric environment, and directly endanger human health. In particular, gravure inks and flexographic inks used for packaging of food, beverages, medicines, daily necessities, and children's toys have the most serious environmental pollut...
