Abstract

The invention discloses ultraviolet light cured water-based gravure ink that is prepared from the following raw materials in percentage by mass: 5%-8% of a binder, 3%-6% of a photosensitizer, 8%-11% of pigment, 2%-4% of industrial ethanol, 4%-10% of an additive, 1%-2% of sodium nitrate and the balance of deionized water, and the sum of the mass percentages of the raw materials is 100%. The invention further discloses a preparation method of the ultraviolet light cured water-based gravure ink, and the problems that in the prior art, the water-based gravure ink is large in viscosity, low in mobility, low in adhesion fastness, poor in stability, low in drying rate and high in cost are solved.

Description

technical field [0001] The invention belongs to the technical field of printing and reproduction, and relates to an ultraviolet light-curable water-based gravure ink, and also relates to a preparation method of the above-mentioned ultraviolet light-curable water-based gravure ink. Background technique [0002] Water-based gravure printing inks are made by mixing polymer resins, emulsions, pigments, solvents (mainly water) and related additives through physical and chemical processes. Water-based ink has the characteristics of no volatile organic solvents, non-flammability, no damage to the health of printing operators, and no pollution to the environment. As a new type of printing ink, water-based ink eliminates the hazards of toxic and harmful substances in solvent-based inks to humans and packaging and printing products, and is especially suitable for packaging that requires strict hygiene conditions such as food, beverages, and pharmaceuticals. Printed products that impr...
