Abstract
The invention discloses a synthetic method of inkjet printing thickener and the thickener. The inkjet printing thickener is prepared through the steps of preparing long-chain fatty alcohol polyoxyethylene ether acrylic acid salt, purifying products, preparing composite emulsion of the long-chain fatty alcohol polyoxyethylene ether acrylic acid salt and polyacrylic acid, dropwise adding reducing agents and phase inversion agents and the like. Through the good salt tolerance and permeability of the long-chain fatty alcohol polyoxyethylene ether acrylic acid salt and good thickening capacity of the polyacrylic acid, interpenetration of a system and a linear structure is formed through a bonding function, and therefore the inkjet printing thickener good in thickening capacity, high in ink compatibility and good in electrolyte resistance is prepared. The experiment result shows that when the synthesized thickener is used for inkjet printing, the thickener has high thickening capacity, electrolyte resistance and ink compatibility, good permeability and the like.
Description
Technical field
The invention belongs to chemosynthesis technical field, especially belong to a kind of textile printing additive synthesis technical field, particularly a kind of synthetic method and products thereof of novel ink-jet printing thickening agent.
Background technology
Ink-jet printed technology is a kind of brand-new stamp mode, it has abandoned the complicated link that Conventional decal needs plate-making, by defeated for the image of digitizing technique process people's computer to control jet ink printing system by special software (RIP) again after CAP (computer color separation in printing system) editor, by direct for special colorant spray printing on fabric, form the PRINTED FABRIC of design requirements, improve the precision of stamp, achieve batch, multi items, multi-color stamp, solving Conventional decal floor space large, seriously polluted etc. is problem.Ink-jet printed and printing effect true to nature, has won the favor of more and more human consumer simultaneously.
And in fact adopt and ink-jet printedly require high to ink dye purity, specific conductivity etc., therefore conventional printing assistant can not add in ink, makes ink-jet printed being difficult to obtain blending dyestuff depth color and luster.Textiles needs through pre-treatment, and employing is invaded stain sodium alginate analog assistant and carried out starching to fabric, low viscous ink is sprayed on fabric and does not occur the problems such as dyestuff imbibition look flower.And in actually operating, during starching, easily there is the problem such as " skew of weft ", " wrinkle print ", " uneven ", " very uneven ", the phenomenon such as " flushing ", " escaping cloth ", " look irregular " will be produced during spray printing, cause ink-jet printed fraction defective higher.So research one directly can be added thickening material in ink to and be seemed particularly important.Give ink dye certain pseudo-plasticity by adding of thickening material, under jet power effect, viscosity reduces, easily from sprinkler on fabric, when ineffective power, viscosity improves, other positions that can remain on not to fabric in original position are permeated, and eliminate the pretreated processing requirement of fabric.
Summary of the invention
The present invention needs according to prior art the synthetic method and the thickening material thereof that disclose a kind of inkjet printing thickener.The synthetic method of a kind of novel ink-jet printing thickening agent that main purpose of the present invention provides.Be characterized in utilizing salt tolerance and perviousness that long-chain fat polyoxyethylenated alcohol acrylate is good and the excellent thickening capabilities of polyacrylic acid, formed the IPN of system and linear structure by association, thus prepare the inkjet printing thickener that a kind of novel thickening capabilities is good, high in ink compatibleness, electrolyte-resistant ability is good.
