Problems solved by technology

Therefore, water-based inks are becoming more and more popular; but at present, water-based inks generally have insufficient performance in terms of dispersibility, gloss, and water resistance, and take a long time to cure, which reduces use efficiency and increases costs. It is also a problem worthy of attention, and the storage effect of ink is also a problem worthy of attention

Abstract

The invention discloses a water-based ink which comprises the following materials in parts by weight: 10-25 parts of a pigment, 25-40 parts of a binding material, 35-70 parts of a solvent, 1-3 parts of a defoaming agent, 1-3 parts of a leveling agent, 2-5 parts of a 5A molecular sieve, 1-2 parts of fumed silica, 2-5 parts of a dispersant, 0.5-1.5 parts of an adhesion promoter, 1-3 parts of ethanolamine, 3-5 parts of triethylamine, 1-3 parts of 2-amino-2-methyl-1-propanol, 2-3 parts of a drying retarder and 1-2 parts of gummy oil. The water-based ink provided by the invention can enhance the adhesion force of the ink, prevents the ink from ink penetration, ink melting and other phenomena, and has high stability, long storage time, a certain anti-drying capacity and low pollution.

Description

technical field [0001] The invention relates to the technical field of ink, in particular to a water-based ink. Background technique [0002] Water-based ink is a uniform paste-like substance composed of binders, pigments, additives and other substances. The binder provides the necessary transfer performance of the ink, and the pigment gives the ink its color. The binder of water-based ink is mainly divided into two types: water-diluted and water-dispersed. There are many types of resins that can be used in the former. The water-dispersed type of vehicle is obtained by polymerizing emulsified monomers in water. It is a two-phase system, in which the oil phase is dispersed in the water phase in the form of particles. Although it cannot be dissolved by water, it can be diluted by water, so it is also It can be considered as an oil-in-water emulsion type. Water-based inks use water as a solvent, and the content of volatile organic compounds is extremely low, which has little...
