Abstract

The invention discloses an alcohol-soluble environmental intaglio aluminum foil ink and a preparation method thereof, belonging to the technical field of intaglio printing. The ink comprises 40-60wt% of fully alcohol-soluble nitrocellulose liquid, 15-30wt% of alcohol-soluble polyamide resin liquid, 6-10wt% of maleic acid resin liquid, 5-20wt% of pigment (dye), 5-20wt% of organic mixed solvent, 1-3wt% of erucamid and 1-3wt% of wax powder. The preparation method comprises the following steps: firstly preparing fully alcohol-soluble nitrocellulose liquid, alcohol-soluble polyamide resin liquid, maleic acid resin liquid and mixed solvent for standby, secondly mixing fully alcohol-soluble nitrocellulose liquid, alcohol-soluble polyamide resin liquid, maleic acid resin liquid, pigment (dye), erucamid and wax powder and processing the mixture through grinding and dispersing to obtain the product. The method of invention adopts lower molecular weight alcohol and ester as solvent so that the residue of poisonous VOC and the exhaust emission are effectively eliminated, and the method is safe, no non-toxic and environmentally friendly.

Description

technical field [0001] The invention relates to an environmentally friendly ink for a gravure printing machine, in particular to an alcohol-soluble environment-friendly gravure aluminum foil ink and a preparation method thereof, belonging to the technical field of gravure printing. Background technique [0002] At present, most of the beer packaging uses aluminum foil printing labels to seal the bottle mouth and neck, such as Zhujiang Beer, Blue Ribbon Beer, Tsingtao Brewery, San Miguel Beer, Kingway Beer, Pure Draft Beer, etc. Most of the existing printing companies still Toluene-containing plastic ink is used for printing, but the ink is not environmentally friendly, and the residue of toxic VOC will cause certain harm to the human body. With the improvement of the economic level, the printing industry continues to develop in the direction of high-end packaging printing and green and environmentally friendly comprehensive printing. All ink manufacturers are researching and...
