Problems solved by technology

[0003] The production process of water-based ink is not perfect. Since the main component of the solvent is water, the ink droplets will diffuse and penetrate into the interior when sprayed on the surface of the substrate, forming marks through penetration and volatilization, so the drying speed of the ink is relatively slow. It is slow, and it is easy to cause print quality problems such as low color saturation of the printed product
Image quality and durability are acceptable when water-based inks are printed on inkjet paper or coated substrates, however when printed on non-absorbent substrates such as metal, glass, and plastics, they do not produce sharp, long-lasting images

Abstract

The invention discloses environment-friendly water-based ink-jet ink and a preparation process thereof. The ink is mainly prepared from, by weight, 25-45 parts of resin binder, 25-55 parts of coloringagent, 30-50 parts of distilled water, 0.5-3 parts of dispersing agent, 0.3-4 parts of antifoaming agent, 1-3 parts of color regulator, 1-3 parts of flowable agent, 0.2-3 parts of desiccant, 1-2.5 parts of adhesion promoter, 1-5 parts of PH regulator and 0.3-2.5 parts of surfactant. The environment-friendly water-based ink-jet ink is used for printing with high image quality and can not only be applied to ordinary daily necessary packages but also be used on the surfaces of plastic, wood, coated metal and other products, the pattern layer is rich, the color is bright, the effect required by apattern designer can be achieved, and the ink does not pollute the environment and is free of odor and toxin, environmentally friendly and suitable for mass production.

Description

technical field [0001] The invention belongs to the technical field of inkjet inks, and in particular relates to a green water-based inkjet ink and a preparation process thereof. Background technique [0002] Various countries pay attention to green printing. The United States and some European countries have not allowed printing companies to use benzene-containing solvent-based inks. Under this background, the sales of water-based inks have increased significantly, and the development prospects are also very good. In many countries, water-based inks have gradually replaced traditional benzene-based solvent-based inks. At the same time, inkjet printing technology, which is the most important in digital printing, has also achieved rapid development in an all-round way. The nanotechnology and ultrafine powder technology related to inkjet printing technology have been improved, and the ink development process has been continuously improved. Inkjet printing is accepted by more ...
