Abstract

The invention relates to a gravure printing ink for packaging and a preparation method thereof. The printing ink is characterized by comprising the following components in parts by mass: 8-20 parts of organic pigments, 10-24 parts of chlorinated rubber, 7-15 parts of carboxymethyl hydroxyethyl cellulose, 15-30 parts of a keto-aldehyde resin, 2-7 parts of pentalyn, 35-50 parts of methyl ethyl ketone, 8-18 parts of methyl soya oil acid, 7-14 parts of toluene, 2-6 parts of phenol, 2-7 parts of a manganese drying-promoter, and 2-6 parts of polyethylene microcrystalline wax. The printing ink provided by the invention has excellent durability and color retention, and after being printed on the surfaces of packaging materials, the printing ink can prevent external substances from invading the packaging materials, so that the packaging materials are not easily corroded; and the gloss, color and luster of the packaging materials can be kept for a long time, thereby achieving a good identification effect.

Description

technical field [0001] The invention relates to the technical field of packaging materials, in particular to a gravure ink for packaging and a preparation method thereof. Background technique [0002] Ink is a uniform mixture composed of colored bodies (such as pigments, dyes, etc.), linking materials, filling (filling) materials, additional materials, etc.; it can be printed and dried on the printed body; it is colored and has a certain flow. Degree of paste-like adhesive body. Therefore, color (hue), body (rheological properties such as thinness and fluidity) and drying performance are the three most important properties of ink. Gravure ink, also called gravure liquid ink, is a stable and colored colloidal dispersion system, which can be coated on a suitable substrate by an appropriate printing method to make it present text patterns and colors and provide information and attractiveness . [0003] At present, the existing gravure inks for packaging on the market have sh...
