Abstract

The invention relates to a gravure composite ink, in particular to an ester-soluble polyurethane ink and a preparation method thereof, belonging to the field of printing inks. In order to overcome the technical deficiencies of the ink in the prior art, such as large odor, high solvent residue, and poor resin fastness, the present invention provides an ester-soluble gravure composite ink and a preparation method thereof, the initial drying performance and tinting strength of the ester-soluble gravure composite ink Excellent, the coefficient of friction is between 0.6-0.7, very suitable for the needs of automatic packaging, and has a very good value for industry promotion.

Description

technical field [0001] The invention relates to a gravure composite ink, in particular to an ester-soluble gravure composite ink and a preparation method thereof, belonging to the field of printing inks. Background technique [0002] With the continuous improvement of people's requirements for the quality of life and the living and development environment, the voice of "green packaging materials" in the packaging market is getting higher and higher, that is, to improve environmental protection performance, choose energy-saving, low-consumption, non-toxic, non-polluting, and easy-to-degrade non-toxic materials. Hazardous packaging materials. "Green packaging materials" is the development trend of packaging and printing materials in the future, and people pay more and more attention to them. Printing ink is one of the most polluted raw materials in packaging materials. "Green packaging materials" call for environmentally friendly ink products to meet high-end products. packag...
