Problems solved by technology

[0004] In the traditional water-based ink production, no additives are added or the addition of additives is not comprehensive, which affects the affinity between the resin and water and the affinity between the color paste and the resin, so the stability of the water-based ink is also poor, and the production process is also more complicated. low added value

Abstract

The invention provides a making method of environmentally-friendly aqueous ink. The environmentally-friendly aqueous ink comprises 20-30% of quick-drying chromogenic resin, 15-20% of filmed form wear and water proofing resin, 10-15% of emulsification resin, 25-30% of a color paste, 8-15% of water and 2-5% of an assistant. The making method comprises the following steps: mixing and stirring above components, uniformly stirring the components, and allowing the components to stand for 2-3 min in order to form a slurry mixture; testing the viscosity of the slurry mixture; and testing the color on corrugated paper through using a color developing wheel according to the sample color in order to obtain the aqueous ink. The aqueous ink is nontoxic and innocuous, contains no organic solvents, and greatly reduces toxic substances residual on the surfaces of printed products, such as packaging cartons; an antifoaming agent or a foam inhibitor is added to the aqueous ink in order to solve the foaming phenomenon of the aqueous ink; and a drying agent is added to adjust the drying speed of the aqueous ink, and an anti-wear agent is added to reach a printing machine rotating requirement and improve the production efficiency.

Description

technical field [0001] The invention belongs to the technical field of printing inks, and in particular relates to a method for making environmentally friendly water-based inks. 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 type and water-dispersed type. There are many types of resins that can be used in the former, such as maleic acid resin, shellac, maleic acid resin modified shellac, Urethane, water-soluble acrylic resin and water-based amino resin, etc. 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,...
