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 multifunctional aqueous printing ink. Through effective selection of components and comprehensive effects of components, a formula with excellent comprehensive properties is provided and the components fully perform effects. polyneopentylene-1, 4-buthylene adipate sebacate glycol and diethylenetriamine as raw materials undergo a polymerization reaction in the presence of dicyclohexylmethane-4, 4'-diisocyanate as a catalyst, the reaction product and trimethylolpropane are crosslinked under action of dimethylcyclohexylamine, and the crosslinked product is subjected to chain extension under action of glycol. The aqueous polyurethane has improved water resistance and caking resistance and has good stability and good adhesion to a base. The used polymer-type dispersant improves dispersibility and stability of the aqueous printing ink. Used origanum oil, Salvia sclarea L. essential oil and tea tree essential oil have wide spectrum antibiosis effects and effectively solve the problem that the printed product goes mouldy so that storage time is influenced.

Description

technical field [0001] The invention relates to an ink, more specifically to a multifunctional 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 of vo...
