Description
Technical field:
The preparation method who the present invention relates to a kind of benzinum modified polyacrylate pigment printing binding agent, belongs to paintingThe synthetic field of material printing adhesive.
Background technology:
The shortcomings such as high and process-cycle is long for traditional dyeing complex process, cost, have risen pigment printing abroad,Especially in the U.S., West Germany and Japan. Be printing adhesive as the key of pigment printing, external relevant grindingStudy carefully also and maintain the leading position always. Being developed so far of foreign binders has the product appearance of four generations: the first generation is stickyMixture be can not be crosslinked macromolecule filming material; The second generation be in adhesive construction, introduced hydroxyl, amino,Carboxyl isoreactivity group, when heating these active groups can with fiber in hydroxyl and amino grade form covalencyKey, thus its application performance improved; Third generation adhesive is in component, to have added self-cross linking monomer, to improveFastness, reduces baking temperature, shortens the time that bakes; The 4th generation adhesive be crosslinked at low temperature type adhesive, its friendshipIn connection agent molecule structure, contain strong active group, can, 100 DEG C of left and right and hydroxyl or amino reaction, both canImprove fastness, can reduce again energy consumption. In addition, by organosilicon component, binder molecule is being carried out to modification abroad,The technology that solves the aspect such as feel and fastness now becomes ripe, and has realized suitability for industrialized production.
Improving the application performance of adhesive and exploring the aspects such as new synthetic method, domestic scholars have also been done notFew research: by selection and the rational proportion of monomer, improved greatly the feel of PRINTED FABRIC; By emulsificationAgent preferably, promoted uniformity and the granularity of dispersed particle; The introducing of self-cross linking monomer, fastness is improved,Binder dosage is reduced; On polymerization, there is employing nucleocapsid theory, preparing soft monomer is core,Hard monomer is the printing adhesive of shell, makes its not glutinous and network blocking of reason soft monomer component in the time of stamp; Somebody carriesGo out to adopt mini-emulsion polymerization, can improve the stability of emulsion, flexibility and the elasticity etc. of film, but really can solveBetween feel and fastness, the kind of the printing adhesive of contradiction and quantity are also little, can realize the skill of suitability for industrialized productionArt is rare report also.
Within 2012, the Textile Chemistry and Dyeing and Finishing Engineering specialty Li Qiang of Institutes Of Technology Of Zhejiang discloses one section of " organosilicon by nameModified polyacrylate pigment printing binding agent " Master's thesis, poly-by preparing a kind of both-end acryloxyEther silicone oil, to polyacrylate modified, synthetic a kind of silicone-modified polyacrylate pigment printing binding agent,In improving PRINTED FABRIC colour fastness to rubbing, improve the feel of PRINTED FABRIC. Its method comprises: firstStep: prepare both-end acryloxy polyether silicone oil and it is characterized; Second step is prepared organic-silicon-modified poly-Acrylic ester coating printing adhesive, is applied to bafta by the pigment printing binding agent of invention, and result shows certainlySilicon the third Copolymer Emulsion Coating printing adhesive consumption processed is 16%, and baking temperature is 160 DEG C, while baking time 4min,Dry, wet the rubbing of PRINTED FABRIC all can reach 4 grades, soft, is all better than current pigment printing used on marketAdhesive. This invention is the prior art that approaches most of the present invention, and this invention has substantially completed and taken into account feel and jailThe object of degree, but effect is all excellent not.

Table three: the bending property of fabric after embodiment of the present invention adhesive stamp
Table four: the surface friction property of fabric after embodiment of the present invention adhesive stamp
Compression performance, bending property and surface friction property can represent the flexibility of fabric, show by above-mentioned threeKnown, diminish through the bafta compressibility after stamp, bending property diminishes, the frictional behaviour of fabric faceIncrease, this is mainly to change because the crosslinked action of adhesive makes the style of original bafta, becauseAdhesive is cross-linked into film on fabric, and this tunic shape material declines fabric bulkiness, and stiffness rises, andHaving overcome original fabric face has groove or uneven, has increased the smooth feeling of fabric. Comparatively speaking,Adhesive described in the embodiment of the present invention is more more outstanding in the performance of each performance.
Above content is only preferred embodiments of the present invention, for those of ordinary skill in the art, according to thisThe thought of invention, all will change in specific embodiments and applications, and this description should notBe interpreted as limitation of the present invention.
