Preparation method of environmentally-friendly water-based ink

Abstract

The invention relates to the field of water-based ink and discloses a preparation method of an environmentally-friendly water-based ink. The preparation method of the environmentally-friendly water-based ink is characterized by comprising the following steps: adding an organic paint, resin, deionized water, dimethyl ethanolamine, a wetting agent, an emulsifying agent, a slow drying agent, an antifoaming agent and a dispersing agent according to a certain proportion; performing dispersion in a stainless steel pot, wherein the formula of color paste comprises 33.5 percent of resin liquid, 30 percent of the deionized water, 0.3 percent of the dimethyl ethanolamine, 0.1 percent of the dispersing agent, 0.2 percent of the wetting agent, 0.5 percent of the emulsifying agent, 0.2 percent of the slow drying agent, 0.2 percent of the antifoaming agent and 35 percent of the organic paint; mixing the materials, stirring the materials for about 1.5 hours, then storing the materials for 12 hours, and performing full chemical reaction. Due to adoption of the technical scheme, a product manufactured by using the process is applicable to printing of coating paper, plastic, double PE paper cups, all milk packages and napkin through high-cable and high-speed printers, and is bright and fine in color, light-resistant, unlikely to fade, alcohol-resistant, waterproof, freezing-proof, and good in anti-wearing effect.

Description

technical field [0001] The invention relates to the field of water-based ink, and relates to a preparation method of an environment-friendly water-based ink. Background technique [0002] Water-based ink is an ink prepared from specific water-based polymer resins, pigments, water, and additives through processes such as dispersion, grinding, modulation, compounding, and filtration, referred to as ink for short. Water-based ink is called a new type of "environmental protection ink" and "green ink" because of its incomparable advantages over traditional inks. The biggest difference between water-based inks and traditional inks is the solvent carrier used. The solvent carrier of traditional ink is an organic solvent, such as toluene, ethyl acetate, acetone, ethanol, etc. The solvent carrier of water-based ink is water, or mixed with a small amount of alcohol. Because water is used as the dissolution carrier, water-based ink has obvious environmental protection and safety cha...

Problems solved by technology

Acrylic resin water-based ink has the advantages of high coloring strength, wear resistance, waterproof, fast drying, and frost resistance. At present, the acrylic resin ink produced by our domestic water-based ink manufacturers only accounts for about 55% of the market. The acrylic resin ink produced cannot meet the requirements of some cutting-edge customers, especially in food-grade printing and packaging such as milk bags, facial tissues, and beverage cups. The water-based ink has been monopolized by foreign countries. This is the remaining 15%, which is also the highest gold content Water-based ink formula, so the domestic price of imported ink is very high, reaching 40-60 yuan per kilogram, and some even as high as 80-90 yuan per kilogram
