Abstract

The invention relates to quick-drying type water-based gold ink and a preparation method thereof. The quick-drying type water-based gold ink is prepared from, by weight, 30-60% of pigment, 10-40% of connecting materials and 20-50% of a solvent. The connecting materials are one or the mixture of two or more of water-soluble modified cellulose ester, polyvinyl alcohol, acrylic copolymer and polyurethane. The quantitative solvent is placed in a stirring barrel, the quantitative pigment is added into the solvent with stirring, and a pigment solution is obtained after the pigment is completely dissolved; the quantitative connecting materials are added into the pigment solution with stirring, stirring is uniformly carried, and the evenly-scattered water-based gold ink is obtained. Compared with the prior art, the quick-drying type water-based gold ink is applicable to intaglio printing, and the problem that some intaglio printing devices in China cause the ink inverted adhesion due to the fact that an oven has the high temperature and no cooling device exits is solved.

Description

technical field [0001] The invention relates to an ink and a preparation method thereof, in particular to a quick-drying water-based gold ink and a preparation method thereof. Background technique [0002] With the continuous development of ink technology to high technology and the continuous improvement of people's awareness of environmental protection, the development of environmentally friendly inks must be considered first in the development of inks in the future. [0003] Developed countries have introduced policies to restrict the application of solvent-based inks in food and medical packaging. In the United States and some European countries, the use of benzene-containing solvent-based inks has been banned and replaced by green and environmentally friendly inks. Other developed countries, such as Japan, Germany, France, etc., are also increasingly using water-based inks in plastic film printing. The United Kingdom has legislated to prohibit the use of solvent-based i...
