Abstract

The present invention provides a flexographic plate water-based ink for high-speed printing and a preparation method thereof. The flexographic plate water-based ink comprises the following components by weight: 30-40 parts of a non-film forming acrylic emulsion, 5-10 parts of an acrylic film-forming emulsion, 15-0 parts of an acrylic resin solution, 30-40 parts of an aqueous paste, 1-3 parts of polyethylene wax, 1-2 parts of a film-forming aid, 0.3-1 part of a leveling agent, 0.1-0.5 part of a defoamer, 3-7 parts of deionized water and a pH modifier. The non-film forming acrylic emulsion is an acrylic emulsion with Tg value no less than 90 DEG C, the acrylic film-forming emulsion is an acrylic emulsion with Tg value less than 30 DEG C, the content of the pigment in the aqueous paste is 40-45%, and the pH modifier reaches pH value of the flexographic plate water-based ink of 8-9.5. The water-based ink can well adapt to printing of high-speed satellite-type press, and has good re-solubility and excellent leveling and trapping effect; and the printed product has high color saturation, bright color and good gloss; therefore, the water-based ink has wide range of applications.

Description

technical field [0001] The invention relates to a water-based ink, in particular to a high-speed printing flexographic water-based ink and a preparation method thereof. Background technique [0002] Flexographic printing, referred to as flexographic printing, is a printing method that uses a flexographic plate and transfers ink through an anilox roller. Traditional flexographic printing uses a rubber letterpress, which cannot print high-quality images. It was not until DuPont of the United States developed a UV-cured resin plate that high-precision printing was achieved. In recent years, in the packaging industry, with the development of technologies such as plate materials, plate making, anilox rollers, and printing plate cylinder sleeve methods, flexographic printing has become the fastest growing and most expensive printing industry in the world. Vibrant typography. [0003] With the increasing safety requirements of product packaging and the increasing emphasis on envi...
