Embodiment 1

[0019] (1) Emulsification: Add 63 grams of methacrylic acid, 59 grams of ethyl acrylate, 20 grams of allyl polyoxyalkylene epoxy ether, 15 grams of hydroxyethyl methacrylate, and diphthalate into a stainless steel kettle. 0.35 grams of allyl ester, 2.2 grams of sodium dodecylbenzenesulfonate, 340 grams of deionized water, stirred and emulsified for 20 minutes to make an emulsion;

[0020] (2) Initiate polymerization reaction: get 20% of the total amount of the emulsion, that is, 100 grams are added to the reactor, the temperature is raised to 75-80 ° C, the mixed solution of 0.069 grams of initiator ammonium persulfate and 1 gram of water is added, and the reaction is initiated. Add 399 grams of the remaining emulsion dropwise at a temperature of 85-90°C, and at the same time add dropwise a mixture of 0.231 grams of ammonium persulfate and 20 grams of deionized water. hours, then cool down to 30-40°C, filter and discharge;

Embodiment 2

[0022] The weight ratio of raw materials is: 64 grams of methacrylic acid, 60 grams of ethyl acrylate, 20.5 grams of allyl polyoxyalkylene epoxy ether, 15.5 grams of hydroxyethyl methacrylate, 0.38 grams of diallyl phthalate Gram, sodium dodecylbenzenesulfonate are 2.25 grams, 345 grams of deionized water; Ammonium persulfate 0.33 grams; Production process is with embodiment 1.

Embodiment 3

[0024] The weight ratio of raw materials is: 65 grams of methacrylic acid, 61 grams of ethyl acrylate, 21 grams of allyl polyoxyalkylene epoxy ether, 16 grams of hydroxyethyl methacrylate, 0.4 grams of diallyl phthalate Gram, sodium dodecylbenzenesulfonate are 2.3 grams, 350 grams of deionized water; Ammonium persulfate 0.35 grams; Production process is with embodiment 1.

[0025] The using method of water-based alkali-swellable rheology agent of the present invention:

[0026] Take 0.5-2% of this product and add it to the pigment printing paste, and adjust the pH value to 7.5-8, stir evenly, and then it can be used for printing.

[0027] The comparison between this product (hereinafter referred to as FS-1000) and Deqian’s WT-113 product and domestic SF-1 product in textile printing paste:

[0028]

[0029] Through the above comparison, it can be known that FS-1000 product has excellent effects of association, thickening, leveling, anti-settling, and anti-water separation,...

Abstract

The invention discloses a water-based alkali swelling rheological agent, which is formed by initiation and polymerization of methacrylic acid, ethyl acrylate, polyalkyl glycol allyl epoxyl ethers, hydroxy ethyl methacrylate, diallyl phthalate, sodium dodecyl benzene sulfonate, deionized water and ammonium persulfate. The rheological agent has the characteristics of strong tackifying and associating performance, good settling resistance and water separation resistance, low cost and simple production; when the rheological agent is added into printing size of textiles, solid materials are not demixed, the suspension stability is good, and the powder is distributed uniformly so that the printed patterns are more complete and fuller and exposed base is not produced.

Description

technical field [0001] The invention relates to an aqueous alkali-swellable rheological agent emulsion, which is used in textile printing paste to increase viscosity, prevent sedimentation and prevent water separation. Background technique [0002] In textile printing, there is a kind of printing that needs to add solid powder to the printing paste to print special printing effects, such as adding pearl powder, gold and silver powder, sequins and other printing. This requires that the added solid powder does not stratify, achieve stable suspension, and evenly distribute the powder. At present, there is no rheological agent specially used for textile printing paste, especially no water-based alkali-swellable rheological agent specially used for textile printing paste. [0003] The water-based alkali-swellable rheology agent is used in the cosmetics industry, but there is no disclosed technology for its raw material composition and preparation method. The water-based alkali-...
