Problems solved by technology

Although water-based ink has been widely used in the printing of coated paper, white cardboard and plastic film, many packaging manufacturers are reluctant to use it due to its cost; and there are still some problems in the printing of ink, for example, ink is easy to dry On the anilox roller, it affects the uniformity of ink transfer; ink is easy to foam and affects color density; water resistance, solvent resistance and abrasion resistance of ink are relatively poor, etc.

Abstract

The invention discloses a low-VOC high-brightness wear-resistant water-based environment-friendly ink which is prepared from the following components in percentage by mass: 25 to 50 percent of water-soluble resin, 7 to 23 percent of dispersing agent, 4.5 to 10 percent of anti-sticking agent, 4.5 to 10 percent of anti-scraping agent, 13 to 19 percent of pigment, 1 to 2 percent of PH regulator and 20 to 30 percent of water, wherein the pH regulator comprises a mixture of a potassium hydroxide aqueous solution and a sodium pyrophosphate aqueous solution, and the mixing ratio of the mixture of thepotassium hydroxide aqueous solution and the sodium pyrophosphate aqueous solution is (1-2): (2-7). According to the ink, the PH of the water-based ink is accurately controlled, the PH regulator is used, the PH is generally controlled to be 8.0-9.5, and it is guaranteed that the ink has good performance such as viscosity, dryness and abrasion resistance.

Description

technical field [0001] The invention relates to the technical field of inks, in particular to a low-VOC high-brightness wear-resistant water-based environmental protection ink. Background technique [0002] Ink is widely used in the printing industry, plastic film, and nylon products. It is mainly composed of binder resin, pigment, solvent, additives and other components. Most of the inks currently used are solvent-based inks. This type of ink will Volatilizes organic solvents that are harmful to the human body and the environment, and some solvents are more toxic and will cause greater harm to the human body, especially some inks that are in direct contact with the human body. To improve the environmental protection of the ink, it is necessary to change the Starting with the ink formulation, new environmentally friendly materials are used to replace traditional toxic and harmful components, while obtaining satisfactory drying speed, usability and good printing adaptability....
