Problems solved by technology

Existing inks used for printing always have various problems: some inks contain benzene and ketone derivatives, which pollute the environment; some inks have poor adaptability, and cannot guarantee the adhesion to different papers. Or the overall adhesion is not strong enough; some inks have good comprehensive performance, but the ingredients are too toxic, which has chronic physical harm to printing workers

Abstract

The invention discloses a water-based ink composition, and the water-based ink composition mainly comprises the following components by weight: 40-80 parts of water, 6-16 parts of a pigment, 4-12 parts of lacquer tree seed kernel oil, 4-12 parts of cottonseed oil, 0. 1-1.0 part of hemicellulose, 1-3 parts of an alkali solution, 2-12 parts of lignin and 2-10 parts of polyol; the water-based ink hasgood colouring property, has high base material adhesion fastness and durability, and has the characteristics of good spreading performance on the surface of a base material. At the same time, the water-based ink does not contain alcohol and ether in additives, and organic amines can achieve VOC-free release characteristic.

Description

technical field [0001] The invention relates to the field of water-based ink, more specifically, it relates to a water-based ink composition. Background technique [0002] Ink is one of the most critical factors to ensure printing quality. Existing inks used for printing always have various problems: some inks contain benzene and ketone derivatives, which are more polluting to the environment; some inks have poor adaptability, and cannot guarantee the adhesion to different papers. Or the overall adhesion is not strong enough; some inks have good overall performance, but the ingredients are too toxic, which has chronic physical harm to printing workers. [0003] Water-based ink, referred to as ink for short, and flexographic water-based ink, also known as liquid ink, is a uniform paste-like substance composed of binders, pigments, additives and other substances. It is mainly composed of water-soluble resins, organic pigments, solvents and related additives through compound ...
