Abstract

The invention discloses a universal environment-friendly gold and silver printing ink for shrink films and belongs to the technical field of printing ink. The universal environment-friendly gold and silver printing ink is prepared from the following raw materials in percentage by mass: 25% to 30% of resin combination, 45% to 60% of solvent combination, 10% to 25% of pigment and 3% to 7% of auxiliaries, wherein the resin combination is prepared from acrylic resin, dinitrocellulose, epoxy resin, polyurethane resin and chlorinated polypropylene, and the solvent combination is a mixture of ethyl acetate, isopropanol, n-propyl acetate and propylene glycol methylether. The printing ink disclosed by the invention is benzene-free and ketone-free and can be universally applied to PVC, PET and OPS thermal-shrink films; the printing ink can be stored for 3 months without discoloring and precipitating and is small in coefficient of friction; and after the printing ink is printed in a manner of being matched with the thermal-shrink films, the shrink films are free of curling and tinting, the print products are in line with environment-friendly requirements and are safe and non-toxic and recoverable, and the printed shrink films have very high resistance to alcohols and tetrahydrofuran, so that the problem in compatibility with glue when the films are subjected to skin-packaging closing is excellently solved.

Description

technical field [0001] The invention relates to the technical field of inks, in particular to a general-purpose environment-friendly gold and silver ink for shrink film and a preparation method thereof. Background technique [0002] The demand for shrink film labels is huge, and its main application fields include beverage bottles (mineral water, juice, cola, beer, etc.), health care products, pharmaceuticals, personal care products and other industries, and its usage is still increasing. With the improvement of living standards, people's requirements for products are not only reflected in the quality of products, but also higher and higher requirements for product packaging. In order to improve the attractiveness of products, product manufacturers will adopt the color design of product bottle labels Compared with the gold and silver colors with more visual impact, the usage of shrink film gold and silver inks is also increasing. [0003] Most of the printing manufacturers ...
