A kind of environment-friendly water-based aluminum foil ink and preparation method thereof

Abstract

The invention discloses aqueous aluminum foil ink with pure acrylic emulsion as a base material and a making method thereof. The ink is composed of the following raw materials in mass ratio: 35-50% of pure acrylic emulsion, 10-30% of pigment, 5-30% of deionized water, 5-20% of ethanol, 3-5% triethylamine, 0-2% of wetting agent, 0-2% of defoamer, 0.1-0.5% of levelling agent, 1-3% of film-forming aid and 0.3-1% of adhesion promoter. The making method comprises adding the raw materials into a reaction kettle according to the mass ratio, stirring at room temperature, milling with a sand mill, and adjusting the pH value to 7.0-8.5 with 0-1% of pH regulator to obtain the aqueous aluminum foil ink. Compared with the prior art, the product has the characteristics of clear printed patterns, water resistance, alcohol resistance and base resistance after being dried, and no decolorizing and fading; the production process is simple and the reaction processes are carried out at normal temperature and normal pressure; the added raw materials are completely converted into a product; the product has extremely low contents of volatile organic compounds (VOC) and has no residue of solvents harmful to human bodies; and the production cost is lowered.

Description

technical field [0001] The invention relates to water-based aluminum foil ink and a production method thereof, in particular to a water-based aluminum foil ink with pure acrylic emulsion as a base material and a production method thereof. Background technique [0002] Since the reform and opening up, with the increasing development of my country's printing industry, the domestic demand for ink is increasing, there are more and more types of ink, the quality grade is getting higher and higher, and the awareness of environmental protection is getting stronger and stronger. At present, the printing industry continues to develop in the direction of high-end packaging printing and environmental protection printing. But at present in our country, the inks used in large quantities in the printing process are basically solvent-based inks. The organic volatiles of these solvent-based inks are not treated and are directly discharged into the air of the workshop, which not only has a c...

But at present in our country, the inks used in large quantities in the printing process are basically solvent-based inks. The organic volatiles of these solvent-based inks are not treated and are directly discharged into the air of the workshop, which not only has a certain impact on the production environment, but also on the health of workers. will also be very harmful
