Description
Technical Field
The invention belongs to the field of papermaking printing industry, and particularly relates to environment-friendly water-based ink and a preparation method thereof.
Background
Ink is an important material for printing packaging materials, and represents patterns and characters on a printing material through printing. With the advance of green development of the traditional industry, the environmental protection requirements of people on industries such as papermaking, printing and dyeing, packaging, printing and the like are higher and higher. For example, in the packaging aspect of food, drink and the like, people not only need to demand high safety of the ink, but also pay more and more attention to environmental protection. Therefore, the development of environment-friendly ink has great development potential.
Nowadays, researches on environment-friendly inks mainly include water-based inks (water inks), ultraviolet curable inks (UV inks), electron beam curable inks (EB inks), soybean inks, and the like. The water-based ink is the most widely environment-friendly ink and is mainly a pasty substance prepared by compounding and grinding water-soluble resin, organic pigment, solvent and related auxiliary agents. The water-based ink is particularly suitable for packaging and printing products with strict requirements on sanitary conditions, such as cigarettes, wine, foods, beverages, medicines, toys for children and the like.
The water-based ink is a uniform slurry-like substance composed of a binder, a pigment, an auxiliary agent and the like. The vehicle provides the necessary transfer properties of the ink and the pigment imparts color to the ink. The water ink overcomes the problem of VOC organic solvent, and compared with the traditional solvent-based ink, the water ink has excellent environmental protection performance. The printing ink does not contain volatile toxic organic solvents, is harmless to the health of printer operators, and is harmless to printed matters and atmospheric environment. The second obvious advantage of the ink is low viscosity and good fluidity. Besides, the ink has the advantages of strong coloring power, high brightness, no corrosion to plates and the like. However, the prior ink produced in China has the problems of low drying speed, poor glossiness, poor water resistance and alkali resistance and the like. The pigment is used as a main source of a water-based ink coloring material, and the poor dispersibility of the pigment in a water-soluble resin has great influence on the optical and rheological properties of the water-based ink, and simultaneously influences the glossiness, smoothness and the like of a printed product to a certain extent. Therefore, there are various problems in developing a novel ink which is environmentally friendly and harmless and has excellent printing performance.

In order to achieve the purpose, the invention provides the following technical scheme:
the environment-friendly water-based ink comprises the following components in parts by weight: 17-23 parts of water-soluble polyacrylic resin, 12-18 parts of cationic rosin size, 30 parts of organic pigment, 2-8 parts of hexadecyl trimethyl ammonium chloride, 2-8 parts of sodium lignosulfonate, 6-10 parts of polyurethane flatting agent, 1-5 parts of organic silicon defoamer, 1-3 parts of ethanol thickener and 12 parts of deionized water.
Preferably, the cationic rosin size is prepared by quaternization reaction of a rosin raw material and a cationic etherifying agent 3-chloro-2-hydroxypropyl trimethyl ammonium chloride.
Preferably, the mass ratio of the reaction materials for the cationization modification of the rosin gum is rosin 3-chloro-2-hydroxypropyl trimethyl ammonium chloride ═ 5: 3.
Preferably, the reaction temperature for the cationization modification of the rosin size is 40 ℃. The reaction time was 4 h.
Preferably, the preparation method of the environment-friendly water-based ink comprises the following specific steps:

And 2, cooling to 40 ℃, and slowly adding 30 parts of cationic modifier 3-chloro-2-hydroxypropyl trimethyl ammonium chloride by using a constant pressure funnel.

Innovation point
1. The environment-friendly water-based ink prepared by the invention overcomes the problem of VOC organic solvent, and has excellent environment-friendly performance compared with the traditional solvent-based ink. The printing ink does not contain volatile toxic organic solvents, is harmless to the health of printer operators, and is harmless to printed matters and atmospheric environment.
2. The environment-friendly water-based ink prepared by the invention has strong tinting strength, high brightness and no corrosion to plates. And the product is stable, has strong acid and alkali resistance, and has good printability for various papers.
3. The rosin size subjected to cationization modification in the preparation process and the water-soluble polyacrylic resin are jointly used as the ink binder resin, so that the ink binder resin has the performances of high glossiness and good water resistance of the rosin size, and also has excellent film forming property, adhesion property, corrosion resistance, weather resistance and the like of the polyacrylic resin.
4. The addition of various auxiliary agents in the preparation process of the invention has a positive effect on the dispersion of the pigment in the ink. The wetting agent hexadecyl trimethyl ammonium chloride and the dispersant lignosulfonate are favorable for improving the property of the water-based ink, and the dispersant and the wetting agent are used for wetting a base material, so that the surface tension of the coating liquid is obviously reduced, and the dispersion performance of the organic pigment in the water-soluble resin is greatly improved. The polyurethane leveling agent can improve the wettability of the base material and control the surface flow, and plays a role in improving the leveling effect, and after the solvent is volatilized, the polyurethane leveling agent forms a monomolecular layer on the surface of the film, so that the gloss of the film is improved, and the coating is promoted to form a flat, smooth and uniform coating film in the drying and film-forming process. For this reason, viscosity control of aqueous inks is important, since viscosity directly affects ink transferability and print quality. In the printing process, the color is light due to low viscosity, and the phenomena of plate contamination, plate pasting and the like are caused due to high viscosity, so that the addition of a proper amount of the ethanol thickening agent is also important. In addition, the defoaming agent can effectively eliminate bubbles generated by the whole water-based ink system and improve the stability of the product, so that the subsequent coating and printing effects are not influenced.
