Abstract

Poly(vinyl alcohol) waterborne intaglio printing UV ink is disclosed. The ink includes, by mass, 3-9% of PVA17-99, 1-5% of ammonium bichromate, 10-15% of pigment, 4-7% of an auxiliary agent, 65-75% ofdeionized water, 3-4% of industrial ethanol, and less than 1% of sodium nitrate. The invention also discloses a preparation method of the ink. Printing with the ink meets the trend of increasing printing demands and continually increasing printer speeds. The ink is solvent-free ink, is low in pollution to air, eliminates damage of some harmful substances in solvent type ink to human and package printed products, improves the printing environment, and is an environmentally friendly product. The ink is not liable to burn, and is stable in ink property, bright in color, free of plate corrosion,simple to operate, low in material cost and good in adhesive force after printing, and a printing plate is easy to clean.

Description

technical field [0001] The invention belongs to the technical field of printing and reproduction, and relates to a polyvinyl alcohol water-based gravure UV ink, and also relates to a preparation method of the polyvinyl alcohol water-based gravure UV 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 solvent, non-flammable, harmless 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 improve the environment for printing ...
