Problems solved by technology

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

Abstract

The invention discloses an environment-friendly water-based ink. By utilizing the comprehensive effects of effective selection and proportioning on the components, the invention provides a formula range with favorable comprehensive properties, so that the components fully perform the functions. The environment-friendly water-based ink is prepared by the following steps: carrying out polymerization on neopentyl glycol polyadipate sebacate-1,6-hexanediol ester diol and 2,2-dihydroxymethylbutyric acid under the catalytic action of diphenylmethane diisocyanate by using a water-based polyurethane binder, carrying out crosslinking under the action of stannous 2-ethylhexoate by using bis(trihydroxymethyl)propane, and carrying out chain extension by using hexanediol, thereby obtaining the environment-friendly water-based ink. The binding resistance and stability of the obtained binder are improved, and the binder has excellent adhesive force for the substrate. The obtained water-based ink has the characteristics of static resistance, environment friendliness, long storage time, favorable staining power, favorable adhesion fastness and the like. The added origanum oil, Litsea citrata essential oil and cinnamon essential oil have broad-spectrum antimicrobial effects, thereby effectively solving the problem that the mildewing of the printing product can influence the storage property.

Description

technical field [0001] The invention relates to an ink, more specifically relates to an environment-friendly 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 ...
