Abstract

The invention provides a water-based ink for gravure printing. The water-based ink comprises the following in proportion by weight: 25 to 35 percent of water-based acrylic film-forming emulsion, 20 to 25 percent of water-based acrylic non-film-forming emulsion, and 30 to 35 percent of water-based resin solution, wherein the water-based resin solution consists of 15 to 25 percent of water, 15 to 25 percent of ethanol, 10 to 15 percent of ammonia water or ethanolamine, and 30 to 40 percent of solid polymer acrylic resin. The water-based ink has the advantages of thoroughly changing the problem of residual organic matter in printed matter, achieving zero pollution emission in the process of drying the ink and reducing harm to operators.

Description

technical field [0001] The invention relates to raw materials in the printing industry, in particular to a water-based ink for gravure printing and a production method. Background technique [0002] In the prior art, most printing inks contain more or less volatile organic compounds, especially the inks used in screen printing, letterpress printing, gravure printing, and lithographic printing contain volatile organic compounds. compound. Since volatile organic compounds generally contain many harmful substances to the human body and the environment, these harmful substances may penetrate through the packaging into food, medicine and other objects that are in direct contact with the human body, so Ink containing volatile organic compounds. Therefore, the World Health Organization and the Chinese government have strictly limited the content of volatile organic compounds in printed matter used for food, medicine and other packaging. There are also some water-based inks with l...
