Waterborne gravure silver ink and production process thereof

Abstract

The invention discloses waterborne gravure silver ink and a production process of the waterborne gravure silver ink. The formula of the waterborne gravure silver ink comprises the following components in parts by weight: 30 to 40 parts of deionized water, 10 to 20 parts of ethanol, 0.1 to 1 part of a surfactant, 0.5 to 1 part of a directional arrangement additive, 40 to 55 parts of waterborne resin solutions, and 10 to 20 parts of waterborne aluminum silver paste. The waterborne gravure silver ink and the production process of the waterborne gravure silver ink disclosed by the invention have the advantages of excellent water resistance, difficult oxidation stain and good anti-settling performance.

Description

technical field [0001] The invention relates to the field of ink preparation in the printing industry, in particular to a water-based gravure silver ink and a production process thereof. Background technique [0002] Water-based gravure silver ink is a kind of gravure ink that uses water-based resin as binder, special water-based gold and silver powder as color developer, and can be diluted by deionized water and ethanol in any ratio. [0003] At present, the inks used by gravure printing companies serving the tobacco system on the market have basically achieved different degrees of water-based inks in the ordinary color inks, while silver inks cannot find suitable products on the market due to various defects. For example, if the drying is not good, the cells are easy to be blocked during the printing process, and the leveling of the ink film is poor. It is not possible to use offset printing or silk screen printing on the surface, and it is easy to hard sedimentation. Co...

Problems solved by technology

[0003] At present, the inks used by gravure printing companies serving the tobacco system on the market have basically achieved different degrees of water-based inks in the ordinary color inks, while silver inks cannot find suitable products on the market due to various defects. For example, if the drying is not good, the cells are easy to be blocked during the printing process, and the ink film has poor leveling properties. It is not possible to use offset printing or silk screen printing on the surface, and it is easy to hard sedimentation. It is easy to oxidize and deteriorate during storage, resulting in serious accidents such as ink scrapping.
