Problems solved by technology

Although water-based inks printed on uncoated papers have long been industrialized (such as printing on uncoated offset paper for book printing, corrugated paper, napkins, and non-woven fabrics), they are not suitable for high-quality inks with low permeability. Materials such as coated paper (such as heavyweight Dowling paper) and plastic and metal foil materials are mostly solvent-based inks that use solvent evaporation to dry

preparation example Construction

[0040] The preparation method of high-speed water-based gravure paper ink of the present invention comprises:

[0041] Firstly, the alkali-soluble styrene-acrylate copolymer is screened, dispersed and ground with high-quality organic pigments through a special process, and a color paste with high color concentration and stable fluid is obtained;

[0042] Secondly, choose a glass transition temperature (Tg) greater than 60 ° C, and good compatibility with alkali-soluble styrene-acrylate copolymers and emulsion-type acrylic acid and acrylate copolymers to improve the drying speed of the ink and the physical properties of the ink film. Mechanical properties such as hardness, mechanical strength, wear resistance and heat resistance.

[0043] Again, select additives such as production, storage stable wetting and dispersion, various additives with excellent leveling and defoaming effects to improve the printability of inks such as pigment wettability, dispersibility, stability, ink ...

Abstract

The invention belongs to the technical field of ink formula study, development and application, and discloses high-speed water-based gravure paper ink as well as a preparation method and application thereof. The high-speed water-based gravure paper ink is prepared from the following ingredients in percentage by mass: 40 to 48 percent of color paste, 30 to 38 percent of emulsion acrylic acid and acrylic ester co-polymers, 3 to 5 percent of wet disperse leveling agents and 17 to 27 percent of deionized water; the color paste is prepared from the following ingredients in percentage by mass: 30 to38 percent of alkali soluble styrene-acrylic ester co-polymers, 30 to 36 percent of organic pigments, 30 to 40 percent of deionized water and 0.3 to 0.6 percent of anti-foaming auxiliary agents. Theink uses water as a medium, and does not contain organic solvents, so that the volatile organic compound (VOC) content is very low; during the printing, no odor basically exists; the environment-friendly effect is good.

Description

technical field [0001] The invention belongs to the technical field of ink formula research, development and application, and relates to a high-speed water-based gravure paper ink and its preparation method and application. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] Solvent-based inks use the volatilization of solvents during the printing process to change from liquid to solid printed images on the printing material. The printing quality of solvent-based ink is good, the printing speed is fast and the ink cost is relatively low, so it is still a large class of ink widely used so far. However, solvent-based inks need to volatilize a large amount of organic solvents after printing (producing a large amount of VOC). If the solvents volatilized into the printing environment are not collected and treated, they will cause harm and pollution to the human body and the environment. Over the years, many...
