Abstract

The invention discloses graphene-based waterborne gravure ink. The graphene-based waterborne gravure ink is prepared from components in percentage by mass as follows: 3%-10% of conductive filler, 0.5%-10% of waterborne resin, 2.5%-40% of water-soluble resin, 2.5%-40% of aqueous emulsion, 0.1%-1% of a dispersing agent, 1%-5% of auxiliaries and 44%-89.9% of an alcohols solvent. The invention further provides a preparation method. The preparation method comprises technological steps as follows: (1), graphene, the dispersing agent, conductive carbon black and waterborne resin are added to a double-planet type stirrer and mixed, a mixture is dispersed, and a pre-dispersion solution is obtained; (2), water-soluble resin, the aqueous emulsion, and the auxiliaries are added to the pre-dispersion solution and stirred uniformly, and a finished product is obtained. According to the graphene-based waterborne gravure ink, environmental pollution caused by traditional solvent type gravure ink is prevented, the waterborne gravure ink develops in order to achieve the advantages of being non-combustible and non-toxic, having less smell, high color emissivity, clear text and complete network and meeting the rapid printing requirement, and the application range is widened.

Description

technical field [0001] The invention relates to the field of printing technology, in particular to a graphene water-based gravure ink and a preparation method thereof, which are mainly used in the field of packaging. Background technique [0002] For a long time, most of the inks used in the gravure printing process of plastic film packaging are solvent-based inks, which contain benzene, toluene, ethyl acetate, xylene, acetone and other organic compounds that are volatile, flammable, explosive, toxic, and irritating. Harmful odors have caused great harm to the human body and the atmospheric environment during the printing process. With the improvement of people's awareness of environmental protection, the quality of existing packaging printed products is poor in weather resistance, anti-yellowing, water resistance, and the residual amount of volatile organic compounds is large, which cannot meet people's needs more and more. Water-soluble resin is used as ink binder, and no...
