Embodiment 1

[0020] In an embodiment of the aqueous ink of the present invention, the preparation method thereof includes the following steps:

[0021] Weigh waterborne polyurethane resin 30%, polyolefin emulsion 20%, lithopone 20%, propylene glycol ether 5%, dimethylethanolamine 3%, monoethanolamine 1%, Tego 805 0.2%, polydimethyl silicon Oxyane 0.3%, glutaraldehyde 2%, Byk 2010 2%, the balance is deionized water. The above weighed components were added to the reaction kettle, and stirred with a high-speed disperser at a speed of 2000 r / min for 60 minutes at room temperature. Mix all materials uniformly to obtain water-based ink.

[0022] See ¡¨1 for the performance test results of the obtained water-based ink.

Embodiment 2

[0024] In an embodiment of the aqueous ink of the present invention, the preparation method thereof includes the following steps:

[0025] Weigh 35% of waterborne polyurethane resin, 25% of polyolefin emulsion, 15% of iron yellow, 8% of propylene glycol ether, 5% of dimethylethanolamine, 2% of monoethanolamine, Tego 803 0.2%, silicone oil 0.3%, isothiazole by weight. 2% of linone, 2% of Dispex G40, the balance is deionized water. The above weighed components were added to the reaction kettle, and stirred with a high-speed disperser at a speed of 2000 r / min for 60 minutes at room temperature. Mix all materials uniformly to obtain water-based oil.

[0026] The performance test results of the obtained water-based ink are shown in Table 1.

Embodiment 3

[0028] In an embodiment of the aqueous ink of the present invention, the preparation method thereof includes the following steps:

[0029] Weigh 35% water-based polyurethane resin, 30% polyolefin emulsion, 15% phthalocyanine blue, propylene glycol ethyl ether 6%, dimethylethanolamine 2%, monoethanolamine 3%, Tego 901w 0.2%, polyether polyester Organic siloxane 0.3%, benzisothiazolinone 2%, Dispex HDN 2%, the balance is deionized water. The above weighed components were added to the reaction kettle, and stirred with a high-speed disperser at a speed of 2000 r / min for 60 minutes at room temperature. Mix all materials uniformly to obtain water-based ink.

[0030] The performance test results of the obtained water-based ink are shown in ¨1.

Abstract

The invention discloses water-based ink which is characterized by comprising the following ingredients in parts by weight: 30-40% of waterborne polyurethane resin, 20-30% of polyolefin emulsion, 15-22% of water-based pigment, 5-10% of propylene glycol monoethyl ether, 1-5% of dimethylethanolamine, 1-3% of monoethanolamine, 0.1-5% of a defoaming agent, 0.1-5% of a flatting agent, 0.2-5% of a sterilizing agent, 1-10% of a dispersing agent and the balance of deionized water. The water-based ink has good dispersibility, heat resistance, adhesion, glossiness, water resistance, abrasion resistance and stability.

Description

Technical field [0001] The invention belongs to the technical field of inks, and particularly relates to a water-based ink. Background technique [0002] Water-based ink is called water-based ink for short. It is mainly made of water-soluble resin, organic pigments, solvents and related additives through compound grinding. Water-based inks are especially suitable for packaging and printing products that require strict hygiene conditions such as tobacco, alcohol, food, beverages, medicines, and children's toys. [0003] Compared with oil-based inks, water-based inks are safe, non-toxic, harmless, non-flammable and non-explosive, and almost no volatile organic gases are generated. The difference between water-based ink and oil-based ink is mainly the difference in solvent. The water-based ink uses water as the solvent, and the content of volatile organic compounds is extremely low, which causes little environmental pollution; the oil-based ink uses organic solvents as the solvent, ...
