Abstract

The invention discloses a polyvinyl alcohol aqueous gravure UV ink connecting material. The polyvinyl alcohol aqueous gravure UV ink connecting material comprises the following components: 4% to 10% of PVA17-99, 3% to 7% of an additive, 1% to 6% of ammonium dichromate, 3% to 4% of industrial ethanol, 70% to 85% deionized water, and less than 1% sodium nitrate. The invention also discloses a preparation method of the polyvinyl alcohol aqueous gravure UV ink connecting material. The method comprises the following steps: step 1, weighing the raw materials; step 2, preparing an ammonium dichromatesolution; step 3, preparing the PVA17-99 solution; and step 4, adding a remaining auxiliary. A photosensitive adhesive is prepared by the water-soluble polymer resin polyvinyl alcohol, a solvent is water, which is non-toxic, non-polluting, low in price, material acquisition is convenient, the photosensitive adhesive is used as the connecting material without solvent evaporation, and is safe and pollution-free. The production efficiency is high, the printing quality is excellent, the color saturation, color intensity and sharpness are obviously better than that of the common ink connecting material, and the UV ink connecting material is very beneficial for achieving healthy green printing.

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 binder, and also relates to a preparation method of the polyvinyl alcohol water-based gravure UV ink binder. Background technique [0002] The key point in the research and development of water-based inks lies in the research on binders. The binders 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. 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 2005, Feng Lianxiang used acrylic acid to modify rosin, and then copolymerized with polyvinyl butyral to obtain a water-based ink binder with excellent adhesion and water solubility. Th...
