Abstract

The invention discloses a novel environmentally-friendly high-speed gravure printing compound ink. The ink comprises, by mass, 25-40 parts of a polyurethane resin, 10-15 parts of polyethylene vinyl acetate, 30-45 parts of an ester alcohol solvent, 0.6-1 part of propylene glycol methyl ether acetate, 5-15 parts of a pigment, 0.3-0.6 parts of a dispersant, 0.3-0.6 parts of polyethylene wax powder, 0.8-1.5 parts of an adhesion promoter, 0.8-1.5 parts of an antistatic agent, 5-8 parts of a delustering liquid, 1-3 parts of delustring powder and 0.3-0.6 parts of an antifoaming agent. The ink has fine and uniform fineness, can adapt to a printing speed of 300m / min, and has the advantages of excellent light stability, excellent chemical drug resistance and no yellow stains.

Description

technical field [0001] The invention relates to the technical field of ink production, in particular to a high-speed reverse printing composite ink. Background technique [0002] Ink is an important material used for printing packaging materials. It expresses patterns and characters on the substrate through printing. The ink includes main components and auxiliary components, which are uniformly mixed and rolled repeatedly to form a viscous colloidal fluid. It consists of pigments, binders, additives and solvents. It is used for various printing of books, periodicals, packaging and decoration, architectural decoration, etc. With the increase of social demand, the variety and output of ink have also expanded and increased accordingly. With the development of printing technology and the printing industry's emphasis on production efficiency and energy saving, the domestic printing industry is rapidly developing into the field of high-speed printing. Generally, inks produced ...
