Abstract

The invention provides a high-speed printing flexographic water-based ink and a preparation method thereof. The flexographic water-based ink of the present invention comprises the following components by weight: 30-40 parts of acrylic non-film-forming emulsion, 5-10 parts of acrylic film-forming emulsion, 15-20 parts of acrylic resin solution, 30-40 parts of water-based color paste, 1-3 parts of polyethylene wax, 1-2 parts of film-forming aid, 0.3-1 part of leveling agent, 0.1-0.5 part of defoamer, 3-7 parts of deionized water and pH regulator; among them, acrylic acid is not The film emulsion is an acrylic emulsion with a Tg value ≥ 90°C, the acrylic film-forming emulsion is an acrylic emulsion with a Tg value < 30°C, the mass content of the pigment in the water-based color paste is 40-45%, and the pH regulator makes the pH of the flexographic water-based ink The value is 8 to 9.5. The water-based ink can be well adapted to the printing of high-speed satellite printing machines, and has good resolubility and excellent leveling and overprinting effects. The printed products have high color saturation, bright colors, good gloss, and a 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...
