Problems solved by technology

[0004] Although many types of water-based inks have been developed on the market, they often have a single function, and there are many problems in dispersibility, gloss and stability. In addition, water-based inks may be produced by raw materials during production and storage. Microorganisms brought in, contaminated by production equipment, introduced by the outside due to improper storage, and the finished printed matter is polluted by the microorganisms introduced by the outside, because the water in the water-based ink is more suitable for the survival and reproduction of microorganisms, making the ink very easy Susceptible to microbial erosion and deterioration, seriously affecting the appearance of packaging products

Abstract

The invention discloses water-based ink. A formula range with the excellent comprehensive performance is provided through the comprehensive effect of effective selection and proportion combination of all components, so that all the components fully play roles; a water-based polyurethane connection material is obtained through the steps that polymerizing is conducted by taking polysuccinic acid octanedioic acid ethylene glycol-1,4-butylene adipate glycol and dimethylolpropionic acid as raw materials under catalysis of xylylene diisocynate, crosslinking is conducted through polyethylene glycol 200 under the action of dibutyl tin diacetate, and then chain extension is conducted through 1,4-butanediol. The adhesive force and stability of the obtained water-based polyurethane connection material are both improved; the obtained water-based ink has the advantages of being free of toxicity, preventing mildew, resisting oxidation and the like and has the very good adhesion and the high printing speed, added origanum oil and leptospermum scoparium essential oil have the broad-spectrum antibacterial effect, and therefore the problem that the storage time of a printed product is influenced by mildew is effectively solved.

Description

technical field [0001] The invention belongs to the field of ink, and more specifically relates to a water-based ink. Background technique [0002] PM2.5 is a pollutant in the atmosphere. Volatile organic compounds account for 21% of the substances that form PM2.5, and about 18% of the volatile organic compounds are produced by solvent-based coatings and ink emissions. Solvent-based coatings and inks need to be diluted with organic solvents, which not only consume fossil energy, but also contain a large amount of toxic and harmful substances such as benzene, toluene, xylene, and formaldehyde, and some of them have a volatilization period of more than ten years. Studies have shown that long-term inhalation of these volatile gases can lead to serious diseases such as aplastic anemia and leukemia. [0003] Water-based inks use water as the diluent and do not contain benzene, toluene, and xylene. Compared with traditional solvent-based inks, they can greatly reduce the emission...
