Problems solved by technology

[0003] The effect of water-based gravure matte printing was achieved by screen printing in the past. There were problems such as strong ink odor and low production efficiency. Later, it was changed to solvent-based gravure printing, which can be used for high-speed gravure printing. Although the production efficiency has been improved, there are also problems. Environmental problems such as high organic solvent residues and large exhaust emissions

Abstract

The invention discloses water-base frosted gravure ink and a preparation method thereof, and belongs to the technical field of printing ink. The water-base frosted gravure ink is a mixed dispersion formed through high-speed dispersing of polyethene wax powder, gaseous silicon dioxide, frost powder, alcohol / water acrylic acid, styrene-acrylate copolymer emulsion, a dispersing agent and an alcohol / water mixed solvent. As ethanol amine is added when resin is dissolved, the pre-dispersibility and solubility of a resin system are improved greatly; the excellent leveling property and stability of the ink are kept; the production efficiency is effectively improved; when the ink is used for printing a product, the release property of a solvent is good; the printed product residue is extremely less; the problem of high residual quantity of the organic solvent is solved effectively; as alcohol and water serve as main solvents of the ink, the preparation cost is low; the ink is free from volatile organic compounds (VOCs); requirements on the cigarette packaging VOCs can be met; and the ink is harmless to a human body, and can meet increasingly strict environmental requirements.

Description

technical field [0001] The invention belongs to the technical field of printing inks, in particular to a water-based gravure matte ink and a preparation method thereof. Background technique [0002] As a kind of printing process, gravure printing has the advantages of thick ink layer, bright color, high saturation, high printing plate durability, stable quality of printed products, fast printing speed and other advantages in the field of printing, packaging and graphic publishing. occupy an extremely important position. From the perspective of application, in foreign countries, gravure printing is mainly used for fine publications such as magazines and product catalogs, packaging printing and printing of securities such as banknotes and stamps, and is also used in special fields such as decorative materials; Printing is mainly used for flexible packaging printing. With the development of gravure printing technology in China, it has also been widely used in paper packaging, ...
