Abstract

The invention relates to the technical field of printing ink, and discloses high-adhesion ink for water-based gravure plastic films. The high-adhesion ink is prepared from the following components inparts by weight: 50 to 70 parts of water-based acrylic resin, 10 to 15 parts of a coloring agent, 15 to 25 parts of a solvent and 5 to 6 parts of auxiliary agents, wherein the base materials of the water-based acrylic resin are dimethyl ester, butyl acrylate and acrylic acid. The preparation method comprises the following steps: weighing the raw materials according to mass parts; then mixing the water-based acrylic resin, the coloring agent, the solvent and the defoaming agent by stirring, and then grinding the mixture until fineness of the raw materials is 15 microns or lower; then adding auxiliary agents except the defoaming agent, and carrying out uniform mixing and stirring again until the viscosity reaches 24-28 s / 25 DEG C of Zahn 4# cup; and finally carrying out filtration and packaging. The ink is safe and environmentally friendly, and is low in volatile organic compound (VOC) content and small in smell; flowability is good; a printed product is high in color concentration, excellent in color and luster and good in adhesion fastness; the printed product has good anti-blocking, anti-migration and anti-friction properties; and the high-adhesion ink can replace solvent-based ink for gravure plastic films.

Description

technical field [0001] The invention relates to the technical field of inks, in particular to a water-based gravure plastic film high adhesion ink and a preparation method thereof. Background technique [0002] With the continuous improvement of people's living standards, environmental protection and green are the general trend of today's printing and packaging industry. Therefore, non-toxic, harmless, non-flammable, non-explosive, low VOC emissions and other requirements have been put forward for gravure plastic film inks. The country has also issued the Environmental Protection Industry Standard of the People's Republic of China HJ / T371-2007 "Technical Requirements for Environmental Labeling Products Gravure Printing" Inks and Flexo Inks". In terms of gravure plastic film surface printing inks, it is imperative to replace solvent-based inks with water-based inks, and corresponding technical environmental protection standards have been formulated for this. This standard s...
