Description

A kind of waterborne digital ink-jet printing sublimation ink and preparation method thereof

Technical field

The invention belongs to digital ink-jet marking ink and preparation field thereof, particularly relate to a kind of waterborne digital ink-jet printing sublimation ink and preparation method thereof.

Background technology

Ink-jet printed technology can be satisfied with human consumer's personalization, diversified demand with its short run, short processes flow process and quick characteristics of paying, and is widely used in every field such as outdoor advertising air brushing, textile inkjet printing.

Ink-jet ink is the key in the inkjet technology, and printing ink can be divided into pigment style and dye-type two big classes according to toner kind difference, can be divided into water-based and solvent-borne type two big classes again by the solvent species difference.Water-base ink is with its low smell, low volatility, thereby has eco-friendly characteristic, looked at by numerous human consumer parents, and pigmented ink is widely used in the outdoor advertising with its good sun-resistant fastness characteristic.Along with the enhancing of entire society's environmental consciousness, be that the advertisement of main raw material is put on agenda with cloth gradually with the trevira.Trevira is one of most important in the world textile fibres kind; And pigment tack on trevira is not good; Therefore must just might be attached to polyester fibre surface by means of special tackiness agent, but the use of tackiness agent tends to make the fabric hardening and influences its soft hand feeling.Dispersed dye can get into the intermolecular fabric coloring that makes of trevira through distillation, do not influence the feel of fabric.Simultaneously the status of dispersed dye in polyester textile is ink-jet printed is very outstanding, and preparation is that the water-base ink of main tinting material has important application value with dispersed dye.

Dispersed dye are water insoluble or be slightly soluble in water, therefore through adopting dispersion agent that dispersed dye are carried out surface-treated, dispersed dye are dispersed in the WATER AS FLOW MEDIUM, and improve the performance of keeping humidity of ink through adding suitable water-miscible organic solvent.Screening to tensio-active agent is then very important, and suitable tensio-active agent can make ink have the surface tension that adapts to shower nozzle and polyester textile simultaneously.

USP 20070107626 is a dispersion agent with the multipolymer of phenmethyl methacrylic ester and methylacrylic acid, makes the black disperse dye ink; Select and have utmost point low solubility the (dispersed dye of 10-5~10-3g) among the patent ZL200410077014.X for use; Adopt the lignin macromolecule dispersing agent that dispersed dye are carried out surface-treated, making the disperse dyes granule median size is the water fever distillation digital ink-jet marking ink of 100~300nm.

Summary of the invention

Technical problem to be solved by this invention provides a kind of waterborne digital ink-jet printing sublimation ink and preparation method thereof, and this ink has good spue fluency and shower nozzle performance of keeping humidity on the large-scale air brushing machine that uses water-base ink, and preparation technology is simple.
