Abstract

The invention discloses a preparation process of environment-friendly water-based ink. The preparation process comprises the following steps: step 1, weighing raw materials; step 2, adding deionized water into a dispersion cylinder, then adding a pigment, carrying out ultrasonic treatment at normal temperature for 10 minutes to prepare an aqueous dispersion liquid of the pigment, then adding a wetting agent and half of a dispersing agent, and carrying out high-speed dispersion and grinding to obtain color paste; and step 3, mixing the color paste with the polyacrylate emulsion, and adding a modified filler, a dispersing agent and a defoaming agent to obtain the environment-friendly water-based ink. According to the invention, the water-based polyacrylate emulsion is used as a film-formingsubstance of the ink; the emulsion has high film-forming property and adhesive force; by adding the modified filler, the phenomenon of ink aging caused by ultraviolet rays can be effectively prevented, the damage caused by the ultraviolet rays to an organic resin base material is reduced, and the water-based ink has water resistance and ultraviolet-resistant stability at the same time; the raw materials are green and environment-friendly, and the water-based ink which is environment-friendly, excellent in comprehensive performance and capable of effectively defending ultraviolet rays is obtained.

Description

technical field [0001] The invention belongs to the technical field of ink preparation, and in particular relates to a preparation process of an environmentally friendly water-based ink. Background technique [0002] Ink is an important material used for printing packaging materials. It expresses patterns and characters on the substrate through printing. Chlorinated polypropylene inks, polyurethane inks, and polyacrylate inks are the most used in printing and packaging. These solvent-based inks contain a large amount of organic solvents such as benzene, toluene, methyl ethyl ketone, and ethyl acetate. During use, the volatilized solvent pollutes the air and endangers the health of the operator. The residual solvent in the packaged product will seriously pollute the food in the package, so water-based ink is becoming more and more important. [0003] Water-based ink is made of water-based binders, organic pigments, solvents and related additives through compound grinding. It...
