Abstract

The invention discloses a water-based flexographic ultraviolet curing ink binder. The water-based flexographic ultraviolet curing ink binder is prepared from 4%-10% of polyvinyl alcohol (PVA), 3%-7% of an auxiliary, 1%-6% of ammonium dichromate, 3%-4% of industrial alcohol, 70%-85% of deionized water and sodium nitrate less than 1%. The invention further discloses a preparation method of the water-based flexographic ultraviolet curing ink binder. The method comprises the steps that the PVA17-99 is prepared; the rest of the auxiliary is added. Photo-sensitive resist prepared from the water-soluble polymer resin polyvinyl alcohol uses water as solvent and is non-poisonous, pollution-free and low in price, materials are convenient to take, and when the photo-sensitive resist is used as the binder, no solvent volatilize, so that the photo-sensitive resist is safe and pollution-free; secondly, the production efficiency is high, the printing quality is excellent, the color saturation, the color intensity and the definition are obviously better than those of ordinary link binders, equipment is easy to clean, the photo-sensitive resist is very beneficial to achieving environment-friendly healthy and green printing, moreover, the photocuring speed of the photo-sensitive resist is improved, and thus the printing efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of printing and reproduction, and relates to a water-based flexographic UV-curable ink binder, and also relates to a preparation method of the water-based flexographic UV-curable ink binder. Background technique [0002] The key point of the research and development of water-based ink lies in the research on the binder. The binder can evenly disperse the pigment particles, make the ink have a certain fluidity, and provide adhesion to the substrate, so that the ink can form a uniform after printing. film layer. The binder of water-soluble ink is water-soluble resin. [0003] At present, the most studied at home and abroad are mainly modified pine water-soluble resins and polyacrylic acid water-soluble resins. For example, in the document "Development of Polyvinyl Butyral Resin Ink Linker for Cigarette Holder Tipping Paper" published in 2005 (new chemical material), Feng Lianxiang used acrylic acid to modify...
