Embodiment 1

[0064] Preparation:

[0065] (1) Preparation of resin solution: Add water-soluble acrylic resin, ethanolamine, ethanol, and deionized water into the resin dissolution kettle according to the formula ratio, and prepare the resin solution at a temperature of 50~60°C;

[0066] (2) Wetting and dispersing of pigments: Take the prepared resin solution and pigments according to the formula ratio and add them to the dispersing mixer for wetting and dispersing of the materials, and the stirring time is about 30~40 minutes;

[0067] (3) Stirring and grinding of pigments: After cooling the dispersed materials to 30~40°C, finely grind and disperse them through grinding equipment, and use mechanical external force to grind the pigments into fine particles until the fineness of the materials is ≤ 10μm;

[0068] (4) Further dispersion of materials: After the ink reaches a fineness of ≤10 μm, add pH stabilizer, anti-sedimentation agent, adhesion enhancer and self-crosslinking acrylic emulsio...

Embodiment 2

[0074] The colored water-soluble environment-friendly composite ink includes by weight percentage:

[0075]

[0076] The preparation method of the composite ink is the same as in Example 1.

Embodiment 3

[0078] The composition of described composite ink is identical with embodiment 1.

[0079] The preparation method of described composite ink is:

[0080] (1) Preparation of resin solution: Add water-soluble acrylic resin, ethanolamine, ethanol, and deionized water into the resin dissolution kettle according to the formula ratio, and prepare the resin solution at a temperature of 50~60°C;

[0081] (2) Wetting and dispersing of pigments: Take the prepared resin liquid and pigments and add them into the dispersion mixer according to the formula ratio to carry out the wetting and dispersing of the materials, and the stirring time is about 25-35 minutes;

[0082] (3) Stirring and grinding of pigments: After cooling the dispersed materials to 30~40°C, finely grind and disperse them through grinding equipment, and use mechanical external force to grind the pigments into fine particles until the fineness of the materials is ≤ 10 μm is enough.

[0083] (4) Further dispersion of mater...

Abstract

The invention relates to water-soluble environmental-protection composite printing ink which comprises the following components by weight: 3-18% of acrylic resin, 20-40% of acrylic emulsion, 12-45% of deionized water, 1-12% of ethanol amine, 1-12% of ethanol, 6-38% of pigment, 0.1-1.3% of pH stabilizer, 0-1.2% of anti-settling agent and 0.5-6% of adhesion enhancer. The sum of components of the composite printing ink is 100%. The invention further discloses a preparation method of the composite printing ink. The composite printing ink does not contain organic solvents such as benzene and ketone and the like, is free of solvent residues, environment-friendly and non-toxic, completely meets environmental-protection and national food hygiene safety requirements, can be used for high-grade package printing such as food packaging, medicine packaging and packaging of articles of everyday use, and is particularly suitable to oriented polypropylene (OPP) film composition (treatment degree achieves 38 dynes or higher).

Description

technical field [0001] The invention relates to a water-based ink and a preparation method thereof, in particular to a water-soluble environment-friendly composite ink and a preparation method thereof. Background technique [0002] General printing inks basically use benzene, ketones or esters as the solvent of the mixed system, and because such solvents are highly volatile and highly irritating, they not only cause serious pollution to the environment, but also It has a great impact on the health of the human body, and it is easy to cause solvent residues in the packaging and printing production process, which will also bring further pollution to the recycling of resources, and it is not suitable for the printing of edible packaging. [0003] Water-based ink, referred to as ink for short, and flexographic water-based ink is also called liquid ink. It is mainly made of water-soluble resin, organic pigment, solvent and related additives through compound grinding. Water-based...
