Problems solved by technology

[0003] At present, maleated rosin esters, polyacrylic acid resins, and modified acrylic emulsions are generally used as binders for high-performance inks. There are many problems in terms of gloss, water resistance, and stability, and high-performance inks take a long time to dry, which seriously affects to printing speed

Abstract

The invention discloses high-performance ink, which comprises following components in parts by weight: 20 to 22 parts of cation water-based polyurethane, 13 to 15 parts of alcohol-soluble polyurethane solution, 20 to 23 parts of water-based pigment, 10 to 12 parts of ethanol, 1 part of chloride-vinyl acetae copolymer resin, 5 to 7 parts of propyl acetate and 20 to 22 parts of water. The high-performance ink overcomes the weaknesses in the prior art that the oily ink has severe pollution and poor water-based ink performance, and has good dispersion performance, heat resistance, adhesion firmness, glossiness, water resistance and high printing speed and good binding force.

Description

technical field [0001] The invention relates to a high-performance ink. Background technique [0002] The difference between water-based inks and oil-based inks is mainly the difference in solvents. Water-based inks use water as a solvent, and the content of volatile organic compounds is extremely low, which has little environmental pollution; oil-based inks use organic solvents as solvents, which cause great environmental pollution. In the flexible packaging industry, since solvent-based inks are mainly volatile and dry, the lower the boiling point of the solvent, the easier it is to volatilize and release toxic gases to pollute the environment. After printing, there are residual toxic substances on the surface, and high The solvent used in performance inks is water, which greatly reduces emissions of organic compounds. [0003] At present, maleated rosin esters, polyacrylic acid resins, and modified acrylic emulsions are generally used as binders for high-performance inks...
