Aqueous base swelling type rheological agent and production method thereof
Technical field
What the present invention relates to is an aqueous base swelling type rheological agent emulsion, is used for the printing in textiles slurry and plays tackify, anti-heavy, the anti-effect that divides water.
Background technology
In printing in textiles, there is a class to need in printing paste, to add pressed powder and prints the special printing effect, as adding stamps such as pearlescence, metal(lic)powder, paillette.This just requires the pressed powder that adds not stratified, reaches suspending stabilized, and powder is evenly distributed.Do not see at present to have to be exclusively used in the rheological agent that the printing in textiles slurry uses, particularly do not see to have to be exclusively used in the aqueous base swelling type rheological agent that the printing in textiles slurry uses.
Aqueous base swelling type rheological agent has the use of opinion at cosmetic industry, but its raw material is formed and the preparation method does not see that public technology is arranged.WT-113 product, homemade SF-1 product in the virtuous modest company of aqueous base swelling type rheological agent product that cosmetic industry uses, its result of use in the printing in textiles slurry is unsatisfactory.
Summary of the invention
The purpose of this invention is to provide a kind of aqueous base swelling type rheological agent, have tackify, anti-ly heavyly, anti-divide water to make good use of especially for what printing in textiles slurry used, and the feature of environmental protection is good, production technique simple aqueous base swelling type rheological agent and production method thereof.
The present invention is compared by raw material weight: methacrylic acid 63-65, ethyl propenoate 59-61, allyl group polyoxy alkyl epoxy base ether 20-21, hydroxyethyl methylacrylate 15-16, phthalic acid two rare propyl ester 0.35-0.4, Sodium dodecylbenzene sulfonate 2.2-2.3, deionized water 360-370, ammonium persulphate 0.3-0.35, through causing, being polymerized;
The product chemical index is as follows:
Outward appearance: little pearl opal emulsion,
Ionic: the moon,
PH value: 2.5-4.5,
Solid content: 30 ± 1%.
The preparation method of aqueous base swelling type rheological agent is:
One, each raw material weight proportioning is:
Methacrylic acid 63-65, ethyl propenoate 59-61, allyl group polyoxy alkyl epoxy base ether 20-21, hydroxyethyl methylacrylate 15-16, phthalic acid two rare propyl ester 0.35-0.4, Sodium dodecylbenzene sulfonate 2.2-2.3, deionized water 360-370, ammonium persulphate 0.3-0.35.
Two, producing and manufacturing technique:
(1) emulsification: in the stainless steel still, add methacrylic acid 63-65, ethyl propenoate 59-61, allyl group polyoxy alkyl epoxy base ether 20-21, hydroxyethyl methylacrylate 15-16, phthalic acid two rare propyl ester 0.35-0.4, Sodium dodecylbenzene sulfonate 2.2-2.3, deionized water 340-350, stirring and emulsifying 20 minutes is made emulsion;
(2) initiated polymerization: get about 20% of emulsion total amount, be that the 100-103 weight part adds in the reactor, be warming up to 75-80 ℃, add the mixed solution of initiator ammonium persulfate 0.069 and water 1, cause, under 85-90 ℃ of temperature, drip remaining emulsion, drip ammonium persulphate 0.231-0.281 and deionized water 20 mixed solutions simultaneously, dropwised in 1-2 hour, 85-90 ℃ of insulation 2-3 hour, be cooled to 30-40 ℃ then, filter discharging, get product.
The present invention selects methacrylic acid, ethyl propenoate, allyl group polyoxy alkyl epoxy base ether, hydroxyethyl methylacrylate, phthalic acid two rare propyl ester monomer copolymerizations for use, wherein phthalic acid two rare propyl ester are that the consumption that cross-linking monomer can make polymerisate have had seldom both had excellent rheological, and allyl group polyoxy alkyl epoxy base ether and ethyl propenoate, hydroxyethyl methylacrylate are used and can make polymerisate soft.So the aqueous base swelling type rheological agent of gained, excellent performance, easily-controlled operation, cost is lower, and it is strong to have tackify association performance, and anti-heavy, anti-branch water is made good use of the production technique characteristic of simple.This product adds in seal slurry preparation, and to regulate pH value be 7.5-8, and it is not stratified to play solid powder, and suspension stability is good, and powder is evenly distributed, and makes the pattern of printing more complete, plentiful, does not produce show-through.
Embodiment
Embodiment 1
(1) emulsification: adding methacrylic acid 63 grams, ethyl propenoate 59 grams, allyl group polyoxy alkyl epoxy base ether 20 grams, hydroxyethyl methylacrylate 15 grams, phthalic acid two rare propyl ester 0.35 restrain in the stainless steel still, Sodium dodecylbenzene sulfonate is 2.2 grams, deionized water 340 grams, stirring and emulsifying 20 minutes is made emulsion;
(2) initiated polymerization: get 20% of emulsion total amount, promptly 100 grams add in the reactor, be warming up to 75-80 ℃, add initiator ammonium persulfate 0.069 gram and the mixed solution that water 1 restrains, cause, under 85-90 ℃ of temperature, drip remaining emulsion 399 grams, drip ammonium persulphate 0.231 gram and deionized water water 20 gram mixed solutions simultaneously, dropwised in 1-2 hour, 85-90 ℃ of insulation 2-3 hour, be cooled to 30-40 ℃ then, filter discharging;

The using method of aqueous base swelling type rheological agent of the present invention:
Get this product 0.5-2% and add in the textile printing pigment, and to regulate pH value be 7.5-8, stir, can use by stamp.
This product (hereinafter to be referred as FS-1000) uses contrast with the WT-113 product of the modest company of moral, homemade SF-1 product in the printing in textiles slurry:
By above contrast as can be known, the FS-1000 product has excellent association, tackify, levelling, anti-heavy, the anti-water effect of dividing, and feel is soft does not have influence to fastness.
