Problems solved by technology

[0002] In the existing technology, my country's printing industry is facing great pressure on environmental protection. Since the ink used in the printing process contains organic solvents, the volatilization and emission of organic solvents will pollute the environment and affect people's health. Therefore, more and more printing companies of users choose low toxicity, environmental protection and safe water-based ink
However, the water-based inks in the prior art have technical problems such as slow drying speed, low gloss, low brightness, poor adhesion, insufficient composite strength, high price, and slow printing speed, which cannot meet the production needs of packaging boxes. Therefore, it is necessary to prepare A high-performance, safe and non-toxic ink to improve the status quo

preparation example Construction

[0035] The method for preparing water-based ink includes the following steps:

[0036] (1) Dissolve the water-based amino resin, water-based acrylic resin, and maleic acid resin in the mixed solvent according to the proportions, and mechanically stir at room temperature until the mixture is uniform to obtain mixed solution A;

[0037] (2) Adding pigments to the prepared mixed liquid A, after mixing uniformly, adding auxiliary agents, and finally adjusting the pH of the mixture to a pH value of 8.0-9.0 with a 0 alkaline solution to prepare the aqueous ink.

[0038] Optionally, the pH value of the mixture is adjusted to 8.0-9.0 by using 0.1 mol / L ammonia water.

[0039] The application of the water-based ink in the packaging box.

[0040] Optionally, the application of the water-based ink in a food packaging box.

[0041] Optionally, the application of the water-based ink in a cosmetic packaging box.

Embodiment 1

[0044] (1) Dissolve the water-based amino resin, water-based acrylic resin, and maleic acid resin in a mixed solvent with a volume ratio of water and ethanol of 10:3 according to a mass percentage of 2:1:1, and mechanically stir at room temperature until the mixture is uniform , Prepare mixed solution A;

[0045] (2) Add carbon black to the prepared mixture A. After mixing uniformly, add defoamer, leveling agent and surfactant, and finally adjust the pH of the mixture to 8.0-9.0 with an alkaline solution to obtain the 述Water-based ink.

Embodiment 2

[0047] (1) Dissolve the water-based amino resin, water-based acrylic resin and maleic acid resin in a mixed solvent with a volume ratio of water and ethanol of 10:4 according to a mass percentage of 2:1.2:1, and mechanically stir at room temperature until they are uniform , Prepare mixed solution A;

[0048] (2) Add titanium dioxide to the prepared mixture A. After mixing uniformly, add defoamer, leveling agent and surfactant, and finally adjust the pH of the mixture to 8.0-9.0 with an alkaline solution to prepare the Water-based ink.

Abstract

The invention provides water-based ink. The water-based ink is prepared from the following components in percentage by mass: 30 to 40 weight percent of water-based amino resin, 20 to 25 weight percentof water-based acrylic resin, 10 to 15 weight percent of maleic acid resin, 1 to 5 weight percent of pigment, 5 to 10 weight percent of mixed solvent and 1 to 5 weight percent of additive. The water-based ink disclosed by the invention has the advantages of low toxicity (no volatile organic benzene and VOC gas), high drying speed, high glossiness, high brightness, good adhesive force, good composite strength, high printing speed and the like; and the preparation method of the water-based ink is simple and easy to implement and convenient to operate, and is a green and environment-friendly operation process.

Description

Technical field [0001] The invention relates to a water-based environmental protection ink, in particular to an environmental protection ink and a preparation method thereof, and belongs to the field of environmental protection. Background technique [0002] In the existing technology, my country’s printing industry is facing great pressure on environmental protection. Because the inks used in the printing process contain organic solvents, the volatilization and discharge of organic solvents will pollute the environment and affect people’s health. Therefore, more and more printing companies Of users choose low-toxicity, environmentally friendly and safe water-based inks. However, the water-based ink in the prior art has technical problems such as slow drying speed, low gloss, low brightness, poor adhesion, insufficient composite strength, high price, slow printing speed, etc., which cannot meet the production needs of packaging boxes, so it needs to be prepared A good performance...
