preparation example Construction

[0018] The preparation method of the water-based flexographic printing ink comprises the following steps: stirring 8.7-47.2% film-forming resin resin emulsion, 0.1-0.3% defoamer, and 40-50% water-based acrylic color paste evenly, and then adding 0.2-2.0 % water-based wax slurry, 2-8% isopropanol, 10-30% ethylene glycol, 0.5-1% ethanolamine, and an appropriate amount of water, stir evenly at high speed, and filter.

[0019] The defoamer is a mixture of one or more of the following substances: acetylenic diol DF-70, DF-75 defoamer, acetylenic diol SEF or 504 surfactant. The water-based wax slurry is 515A wax slurry, v-815 wax slurry, W19 wax slurry or PT60 wax slurry.

[0020] Described film-forming resin emulsion is acrylic resin emulsion, and the preparation method of this acrylic resin emulsion is: (1) first pre-emulsifies mixed monomer, part emulsifier, deionized water according to a certain proportion at room temperature and makes stable milky white Pre-emulsion; (2) Add a...

Embodiment 1

[0037] Stir 8.7% acrylic resin emulsion (film-forming resin emulsion), 50% water-based acrylic color paste, 0.3% DE-70 (defoamer), then add 1.7% 515A wax paste (water-based wax paste), 6% isopropyl Alcohol, 30% ethylene glycol, 0.70% ethanolamine, and an appropriate amount of water, stir evenly at high speed, and filter. The above percentages are all percentages by weight.

Abstract

The invention relates to a waterborne soft printing ink comprising the components: film-forming resin emulsion of 8.7-47.2wt percent, waterborne acrylic color paste of 40-50wt percent, antifoam agent of 0.1-0.3wt percent, waterborne wax paste of 0.2-2.0wt percent, isopropyl alcohol of 2-8wt percent, ethylene glycol of 10-30wt percent, ethanolamine of 0.5-1wt percent and water of the rest percent. The invention further provides a method to prepare the waterborne soft printing ink. The waterborne soft printing ink of the invention is nontoxic and environmental friendly, has good safety, stable performance and good adaptability to coated art paper printing, and can be continuously used in printing without mackle, has clear printing effect and low production cost.

Description

technical field [0001] The invention relates to a water-based flexographic printing ink and a preparation method thereof. Background technique [0002] The rapid development of flexographic printing (method) technology has greatly promoted the process of ink desolvation. Flexographic printing technology uses flexible rubber letterpress or photosensitive resin plate printing, which requires the use of non-organic solvent-based inks that are non-corrosive to the plate. . The traditional flexible use of rubber letterpress cannot print high-quality images. It was not until 1973 that DuPont of the United States developed a resin plate with ultraviolet light curing that it began to print high-precision prints. In recent years, in the packaging industry, due to the plate (polymer photosensitive resin plate), plate making (computer-to-plate), anilox roller (laser engraved ceramic anilox roller) and closed doctor blade, printing plate cylinder sleeve method, semi-permeable The prom...
