Abstract

The invention discloses ultraviolet light-cured water-based flexographic printing ink. The printing ink is prepared from the following raw materials in percentage by mass: 5%-9% of a binder, 2%-7% ofa photosensitizer, 13%-17% of pigment, 3%-4% of industrial ethanol, 5%-8% of an additive, 0.5%-2% of sodium nitrate and the balance of deionized water, wherein 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 flexographic printing ink. The problem that in the prior art, the water-based flexographic printing ink is large in viscosity, low in mobility, low in adhesion fastness, poor in stability, low in drying rate and high in cost is 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 flexo printing ink, and also relates to a preparation method of the above-mentioned ultraviolet light-curable water-based flexo printing ink. Background technique [0002] Water-based flexo 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 produc...
