[0004] Water-based ink, as an environmentally friendly ink, has become the development direction of the industry. The initial water-based ink is made of rosin acid amine salt as the main binder. The binder is unstable in water media, so the ink is volatile during storage. Light, thinning, slow drying, poor water resistance, easy to cause paper shrinkage and other disadvantages
These disadvantages have restricted the gravure printing and flexographic printing in our country, and we have to use high-grade imported high-grade water-based inks, which virtually increases the printing cost and limits the development of my country's printing industry.

Embodiment 1
[0049] Water-based inks are made from the following ingredients:
[0050]
[0051] (1) Material preparation and weighing: Weigh the pure acrylic resin, pigment, filler, defoamer, fumed silica, surfactant, wetting and dispersing agent, water, and alcohol one by one in proportion for later use;
[0052] (2) Mixing and stirring: Mix the pure acrylic resin, pigment, filler, defoamer, wetting and dispersing agent, and alcohol prepared in step (1) in order, and add 2 / 3 of the total water first. , at a low speed of 200-400 r / min, feed in turn under stirring, and stir for 10-15 minutes;
[0053] (3) Sand mill dispersion: transfer the uniformly stirred mixture in step (2) into a sand mill for sand mill dispersion, wash the mixing container with 1 / 3 of the total water consumption, add water to the sand mill, and Grind in the mill for 3 to 4 times. When the particle size of the mixture is 150-260nm, the grinding and dispersion are completed;
[0054] (4) Subsequent treatment: Stir the...

Abstract
The invention provides special water-based ink for printing tipping paper for a cigarette. The special water-based ink comprises pure acrylic resin, pigment, packing, a defoamer, fumed silica, surfactant, wetting dispersant, water and alcohol. A preparation method of the water-based ink is also provided by the invention. Compared with other ink for printing the tipping paper for the cigarette, the special water-based ink for printing the tipping paper for the cigarette disclosed by the invention has the advantages that the ink can be diluted by pure water; the consumption is reduced; and the ink does not burn or blast, does not belong to dangerous chemicals, and increases the printing, transporting and storing safety. The water tolerance, the curling resistance and the printing adaptability of the ink are greatly improved; and the printing effect can be equivalent to those of alcohol-soluble ink and solvent-based ink. In a word, the water-based ink disclosed by the invention is simple in cost, low in price, good in printed adhesive force, strong in water resistance, and fast to dry. Thus, the water-based ink is especially suitable for package printed matters such as foods, beverage and medicaments.
Description
technical field [0001] The invention relates to the field of printing raw materials, in particular to a water-based ink specially used for printing cigarette tipping paper and a preparation method thereof. Background technique [0002] After the tipping paper ink for cigarettes is improved from benzene solvents to alcohol ester solvents, although the toxicity is improved compared with benzene inks, the flammability has not been improved. [0003] With the introduction of the national standard YC171-2009, there are higher requirements for the VOC and heavy metal content of cigarette tipping paper. On October 8, 2010, the International Tobacco Control Policy Evaluation Project (ITC) organized a meeting on tobacco control Published a scientific research report, the data showed that 13 Chinese domestic cigarette brands were detected to contain heavy metals, and their content was more than three times higher than that of Canadian cigarettes. Therefore, it is proposed to improve ...
