Abstract

This invention relates to a method for preparing water-soluble Au/Ag ink, which comprises: Au/Ag powder 20-30 wt.%, acrylic acid emulsion 55-65 wt.%, 15% polyvinyl alcohol 4-6 wt.%, gaseous SiO2 1-3 wt.%, dispersant 2-4 wt.%, wetting agent 0.3-1.0 wt.%, film-forming agent 3-5 wt.% and antifoam 0.2-0.4 wt.%. The water-soluble Au/Ag ink has such advantages as high water leakage resistance, high adhesiveness, high corrosion resistance, high electrostatic resistance, good anti-aging capacity, no color change, no fading, simple application process, no toxicity to operators, no environmental pollution, no flammability and no explosion. The water-soluble Au/Ag ink can be used to paint packages of cigarette and food as a substitute for Al/Pt composite paper.

Description

technical field [0001] The invention relates to an ink used in the printing industry, in particular to a water-soluble gold and silver ink and a preparation method thereof. Background technique [0002] Due to the different solvents used, inks are divided into water-soluble inks and solvent-based inks. The inner lining paper for cigarette packaging is to print a layer of gold ink or silver ink on the paper base. The traditional gold and silver inks are all solvent-based inks. The solvent is flammable benzene or benzene compounds. Some products also contain formaldehyde, which is volatile and highly polluting. A large amount of toxic residues will be produced on the printed matter, and the function is single. . There are many papers that cannot be endowed with some special functions after printing, such as waterproof and mildew-proof. To solve these problems, it is necessary to develop a new type of printing material that is non-toxic, tasteless, and has special functions ...
