Abstract

The invention relates to a manufacturing method of a soy-protein-type water-based decorative paper printing ink. The manufacturing method comprises the following steps of: weighing 50-60% of water, 1-3% of ethanol, 4-8% of propylene glycol, 0.2-0.8% of mildew preventive, 0.2-0.8% of a water-based antifoaming agent, 2-8% of ammonia water, 20-26% of modified soy protein and 4-10% of caprolactam; adding the water, the ethanol, the propylene glycol, the mildew preventive, the water-based antifoaming agent and the ammonia water in a stirring tank proportionally; adding the modified soy protein and caprolactam after stirring uniformly; stirring in a high-speed stirring machine at 20-25 DEG C for dissolving, regulating the pH value within 8.0-8.5 to obtain grinding resin solution, adding auxiliary materials such as a pigment to obtain the water-based decorative paper printing ink; and adding the grinding resin solution in the auxiliary materials such as the pigment and water-based acrylic resin to obtain a water-based diluent, wherein the water-based diluent and the water-based decorative paper printing ink are used compositely in the printing process. The invention provides an environment-friendly manufacturing method of the water-based decorative paper printing ink.

Description

technical field [0001] The invention belongs to the technical field of water-based ink for decorative paper, and in particular relates to a preparation method of soybean protein-based water-based ink for decorative paper. Background technique [0002] Ink is the most basic raw material in the printing industry. It is mainly composed of resin linkers, pigments and organic solvents (such as benzene, hydrocarbons, esters). These organic solvents not only bring harm to the health of workers in the printing industry, but also greatly pollute the environment. In recent years, with the continuous development of material science, the structure of coatings and ink products has also undergone great changes accordingly. Developed countries follow the development trend of "green and environmental protection", use water instead of organic solvents, and have developed many varieties of water-based inks for printing paper, plastic films, packaging bags and other special printed matters. ...
