Abstract

The invention provides an inkjet printing thickener and a method for preparing the same. The method for preparing the inkjet printing thickener comprises the following steps: mixing aqueous ammonia with an acrylic monomer until the pH value of the mixture is 6.5-7, adding a cross-linking agent, stirring and mixing to prepare a water phase; mixing an emulsifier with an organic solvent to prepare an oil phase; adding and stirring the water phase to the oil phase, dropwise adding aqueous initiator solution, polymerizing for 1-4 hours at 50-80 DEG C, reducing temperature, discharging, adding a phase transfer agent, and stirring fully and uniformly to obtain the finished product. The inkjet printing thickener provided by the invention has high solid content, moderate viscosity and strong electrolyte resistance and can be used by adopting a padding process during pre-treatment for inkjet printing to ensure that the printed patterns have clear outlines, deep color and no infiltration.

Description

Inkjet printing thickener and preparation method thereof
Technical field
The present invention relates to dyeing, be specifically related to a kind of inkjet printing thickener that in ink-jet printed technique, uses and preparation method thereof.
Background technology
Ink-jet printed technology is a kind of brand-new stamp mode, it has abandoned the complicated link that traditional stamp need to be made a plate, and direct spray printing on fabric has improved the precision of stamp, realize short run, many kinds, multi-color stamp, solved the problems such as traditional stamp floor space is large, seriously polluted.Simultaneously ink-jet printedly spend back flexibly size and printing effect true to nature with it, won more and more human consumers' favor.
And the printing ink that in fact can adopt spraying technique to be sprayed on the fabric only has minute quantity, and because the requirement of strict dyestuffs purity and continuous injection are to the required electric conductivity requirement of ink, other used printing assistants all can not be added in the ink, therefore ink-jet printedly are difficult to obtain blending dyestuff depth color and luster.After textiles must pass through sufficient pre-treatment, employing thickening material dip treating, low viscous printing ink just can be applied on the fabric.And in ink-jet printed technique, act on thickening material on the fabric and can prevent from being ejected into dyestuff imbibition on the fabric, impel dyestuff under humid tropical condition, to be combined with fiber, obtain certain soaping fastness and crock fastness; Owing to form uniform slurry at cloth cover, the fine ink droplet of ejection accurately location absorbs simultaneously, and fineness and the uniformity coefficient of spray printing pattern flower type just are fully guaranteed.
The selection of pretreating reagent is different and different according to the dyestuff composition that contains in the ink.Conventional thickening material can not satisfy ink-jet printed requirement, the scientific worker has done some trials, as add toughener, can improve reactive dyestuffs on dye the set effect, reduce imbibition, disclose a kind for the treatment of process of digital ink jet fabric such as patent CN1707017A, wherein treatment solution is the aqueous solution of thickening material and/or cationic auxiliary.Patent CN101381934 then discloses a kind of color-fixing method and equipment of inking and printing on cotton with active ink, wherein the fabric pre-treatment is adopted and first thickening material is mixed with former paste, other auxiliary agents are added in the former paste after with water dissolution, stirring is modulated into pretreatment fluid again.And in actual production, the different ions auxiliary agent can not be bathed use altogether, and the thickening material high viscosity also can make the operation of padding machine be difficult to carry out.Patent CN101100808 discloses a kind of normal-pressure low-temperature plasma preprocessing technique of pigment ink digital injection stamping fabric, relates to plasma surface modification and processes, and treatment process is comparatively complicated.
Summary of the invention
The technical problem to be solved in the present invention is: solve the technical problem that existing thickening material can not satisfy ink-jet printed requirement, the invention provides a kind of inkjet printing thickener and preparation method thereof, its solid content height, modest viscosity, potential resistance to electrolyte contamination ability are strong, can use in conjunction with padding technique during ink-jet printed pre-treatment, applicable to the pre-treating technology that pigment inkjet stamp, reactive dye ink are ink-jet printed, acid dye ink is ink-jet printed of cotton, silk, polyester piece good.
The technical scheme that the present invention solves its technical problem employing is: a kind of preparation method of inkjet printing thickener, and it is mixed to pH value 6.5~7 with ammoniacal liquor and acrylic monomer, and the adding linking agent mixes and is made into water; Emulsifying agent and organic solvent are made into oil phase; Under stirring state, water is added in the oil phase, drips initiator solution, 50~80 ℃ of lower polymerization times of preparation temperature 1~4 hour, cooling discharge adds the phase inversion agent, fully stirs evenly, and obtains finished product.
