Embodiment 1

[0015] A kind of water-based ink, this water-based ink is made up of the component of following weight ratio: 30 parts of water-based polyurethane resins (number-average molecular weight 100,000), 35 parts of water-based magenta pigments, 3.8 parts of propylene glycol, 1.2 parts of dimethylethanolamine and water 30 servings.

[0016] The above water-based ink is prepared by the following method: add water-based polyurethane resin, propylene glycol, dimethylethanolamine, and water into the mixing tank in proportion, add water-based magenta pigment while stirring, stir on a high-speed mixer for 15-30 minutes, and then sand Disperse in a mill, and the ink product will be obtained when the fineness reaches below 5 microns.

Embodiment 2

[0018] A kind of water-based ink, this water-based ink is made up of the component of following weight ratio: 30 parts of water-based polyurethane resins (number average molecular weight 150,000), 30 parts of water-based yellow pigments, 3.8 parts of propylene glycol, 1.2 parts of dimethylethanolamine and 35 parts of water share.

[0019] The aqueous ink of the present embodiment can be prepared according to the method identical with embodiment.

Embodiment 3

[0021] A water-based ink, the water-based ink is composed of the following components by weight: 35 parts of water-based polyurethane resin (100,000 number average molecular weight), 30 parts of water-based phthalocyanine blue pigment, 3 parts of propylene glycol, 1.2 parts of dimethylethanolamine, 0.8 parts of fungicide and 30 parts of water.

Abstract

The invention relates to an aqueous ink comprising following components by weight proportion: 30-35 parts of waterborne polyurethane resin, 30-35 parts of aqueous pigment, 3-5 parts of propanediol, 1-1.5 parts of dimethylethanolamine and 20-30 parts of water. The aqueous ink of the invention has excellent printing adaptability, is suitable for high-speed printing, meanwhile, has high temperature resistance, excellent gloss, and excellent adhesion force and water resistance.

Description

technical field [0001] The invention belongs to the field of ink, in particular to a water-based ink. Background technique [0002] Water-based ink is referred to as water-based ink for short. The main difference between water-based ink and oil-based ink is the difference in solvent. Water-based ink uses water as a solvent, which has extremely low VOC content and has little environmental pollution; oil-based ink uses organic solvents (toluene, xylene, industrial alcohol, etc.) for the solvent. In the flexible packaging industry, since solvent-based inks are mainly volatile and dry, the lower the boiling point of the solvent, the easier it is to volatilize and release toxic gases to pollute the environment. After printing, there are residual toxic substances on the surface, while water-based inks The solvent used in the ink is water and ethanol excluded from the VOC list, which can greatly reduce VOC emissions. [0003] At present, water-based inks generally use maleic rosi...
