Problems solved by technology

[0008] The technical problem to be solved by the present invention is to provide a water-based ink with high surface energy, poor adhesion on the plastic film, poor wetting effect and fast surface drying speed in the existing technology, and to provide a water-based ink with good adhesion on the plastic film. Excellent surface drying speed, small emulsion particle size, good wettability core-shell structure acrylate emulsion; the ink prepared by using the core-shell structure acrylate emulsion has excellent adhesion, and can be printed in water after film formation. After cooking for 30 minutes, the adhesion still reaches level 0; smooth printing can be achieved on the nozzle, ensuring the ability of continuous or intermittent production

Abstract

The invention discloses water-based plastic ink-jet high-adhesion ink and a preparation method thereof. The water-based plastic ink-jet high-adhesion ink comprises the following raw material components in parts by weight: 6-20 parts of water-based acrylate emulsion, 8-20 parts of water-based color paste, 10-20 parts of an organic solvent, 100-140 parts of deionized water, 1-4 parts of a coalescing agent, 1-8 parts of a surfactant, 1-6 parts of a flatting agent and 1-6 parts of a defoaming agent. The emulsion-based water-based plastic film ink-jet printing ink is safe, environmentally friendly, low in VOC content, small in odor, low in viscosity, moderate in surface drying speed and good in wettability; when the ink is used for printing a test picture on a printing nozzle continuously for 2 hours, a test strip is free of broken lines, oblique lines and the like before and after printing, then the ink is closed and standby for 2 hours, the printing test is performed again, the test strip is intact and free of broken lines and oblique lines, and the ink is excellent in performance.

Description

technical field [0001] The invention relates to the technical field of inks, in particular to an emulsion type water-based plastic film inkjet printing ink and a preparation method thereof. Background technique [0002] Inkjet printing technology is a non-contact digital printing technology successfully developed in the late 1970s and early 1980s. Monochrome and color text and image printing. It has almost no restrictions on printing media, except for ordinary paper, it can directly spray images onto textiles, plastics and other media. It should be noted that there are mainly two types of inkjet printers on the market today, piezoelectric type (eg products of Epson company) and foaming type (eg products of HP, Canon company). Piezoelectric inkjet printers have nozzles at one end of the ink chamber, and piezoelectric materials (mostly lead-aluminum-titanium piezoelectric crystals) at the other end. After the drop is ejected, the ink cartridge is replenished in time by the ...
