Problems solved by technology

Although it is easier to make the coating and printed image water-resistant by using a water-resistant adhesive, it often has a great impact on the color performance of the image and the weather resistance, light resistance, and aging resistance of the coating—the color is easy to whiten, and the color changes with time With the change of time, it becomes less bright, the coating becomes yellow, brittle, etc., that is, the durability is not enough. Therefore, the development of a special adhesive for digital inkjet printing ink-absorbing coating has become an urgent issue in the digital inkjet printing material production industry. topic

Abstract

The invention discloses an adhesive for a digital inkjet printing ink-absorption coating, which is prepared from soft monomers, hard monomers, an emulsifying agent, protection glue, an initiator, a pH regulating agent and water. The adhesive for the digital inkjet printing ink-absorption coating, which is prepared by the invention, has the advantages of uniform latex particle distribution, stable product quality, good compatibility and no demulsification and can be mixed with a cation system; the water resistance of a digital inkjet printing ink-absorption coating which is subsequently prepared is guaranteed; and as soon as the adhesive is put in a printing machine, the adhesive is cured immediately without placement for solidification, and the printing color is vivid.

Description

technical field [0001] The invention relates to a preparation method of an adhesive for ink-absorbing coating of digital ink-jet printing. Background technique [0002] Digital color inkjet printing is a non-impact, dot-matrix printing technology. Ink droplets are directly ejected from micropores to specific positions on the surface of the medium to form images. Compared with traditional printing technology, it has the characteristics of small equipment size, fast and convenient, and environmental protection; compared with laser, needle punching, thermal sublimation and silver salt image output methods, it has low cost, easy colorization and digitization, and the printing format is not affected. restrictions etc. Therefore, with the development and popularization of digital technology, it has been widely used in aspects such as large-format exhibitions, indoor and outdoor advertisements, high-resolution image (photo) output, printing, proofing, and office automation.
