Problems solved by technology

[0003] At present, the existing inks suitable for gravure printing require that its viscosity, tinting strength, adhesion fastness and heat resistance and other parameters meet the needs of ordinary use environments. This will limit the application range of the ink. In order to expand the gravure The application range of printing inks has continuously increased the requirements for the viscosity, tinting strength, adhesion and heat resistance of such inks. It is a technical problem that needs to be solved in this field

Abstract

The invention discloses gravure printing ink, which is prepared from the following raw materials in parts by weight: 15-20 parts of epoxy resin, 10-15 parts of butyral resin, 2-3 parts of kaolin, 2-3parts of calcium hydroxide, 2-3 parts of barium sulfate, 20-26 parts of ethyl acetate, 6-8 parts of nano diatom ooze, 5-6 parts of matte powder, 10-12 parts of titanium dioxide, 8-10 parts of rosin, 0.5-1 part of a dispersing agent and 40-50 parts of a solvent. The gravure printing ink is low in price of the used raw material, and does not contain benzene harmful substances; the product is safe and environmentally friendly, high in adsorption ability, and good in wear resistance and glossiness.

Description

technical field [0001] The invention relates to the field of gravure printing, in particular to a gravure printing ink. Background technique [0002] As one of many printing methods, gravure printing occupies an important position in the fields of printing, packaging and graphic publishing due to its many advantages such as thick ink layer, bright color, high saturation and stable quality of printed products. From the perspective of application, in foreign countries, gravure printing is mainly used in fine publications such as magazines and product catalogs. In addition, it is also used in special fields such as decorative materials; in China, gravure printing is mainly used in packaging printing. With the development of printing technology, gravure printing has also been widely used in paper packaging, wood grain decoration, leather materials, and pharmaceutical packaging. [0003] At present, the existing inks suitable for gravure printing require that its viscosity, tint...
