Abstract

The invention relates to an environment-friendly water-based gravure ink and a preparation method thereof. The environment-friendly water-based gravure ink is prepared from the following materials inparts by weight: 30 to 40 parts of water-based polymer, 20 to 30 parts of organic pigment, 0.05 to 0.15 part of defoaming agent, 0.3 to 0.9 part of hydrophobic agent, 0.1 to 0.6 part of leveling agent, 0.1 to 1 part of water-based anti-settling agent, 1 to 2 parts of pH stabilizer, 1 to 2 parts of filler and 10 to 40 parts of deionized water. According to the environment-friendly water-based gravure ink and the preparation method thereof provided by the invention, processed by the advanced formula, the environment-friendly water-based gravure ink has the advantages of good printing effect, high adhesion, non-ignitability, inexplosiveness, non-toxicity and the like, does not impair the health of pressmen, and does not pollute the atmospheric environment, so the environment-friendly water-based gravure ink is a preferred environment-friendly water-based ink; the environment-friendly water-based gravure ink has good stability and heat resistance, and cannot be faded under a harsh environment after a long time, and the use of the filler and the leveling agent improves printing leveling, improves color saturation, and improves the wear resistance of the ink to a certain degree; moreover, the environment-friendly water-based gravure ink has extremely high grinding consistency, the usage of conventional ink is changed, and the cost in use is reduced.

Description

technical field [0001] The invention relates to the technical field of chemical coatings, in particular to an environment-friendly water-based gravure ink and a preparation method thereof. Background technique [0002] In the flexible packaging industry, since the solvent ink is used in a volatile and dry manner, the lower the boiling point of the solvent, the faster the ink will evaporate and dry, so the solvent ink will release polluting and toxic gases, and at the same time, on the surface of the printed matter. Hazardous substances remain. With the improvement of people's awareness of environmental protection, there is an urgent need for green and environmentally friendly printing materials. Water-based inks use water as a solvent, have extremely low VOC content, have little environmental pollution, and effectively reduce the damage to the human body. They are green and environmentally friendly printing materials. . [0003] But, the water-based ink in the prior art, b...
