Problems solved by technology

Although this invention has certain advantages, the radiation process has high safety and equipment requirements, which limits its wide production and application
[0004] Chinese patent CN1110507C discloses a method for preparing a thickener for printing and dyeing with acrylic acid, which is characterized in that the synthesis reaction is initiated by chemical and radiation compounding, the reaction has no induction period, is stable, and is easy to control, and the initial temperature of the reaction system is 41- 50°C, although this invention adopts compound initiation, the thickening effect of the product is average, and the color yield is also low
[0006] The products obtained by the existing synthetic methods of pigment printing thickeners generally have disadvantages such as unsatisfactory thickening effect, poor electrolyte resistance and poor color yield.

Embodiment 1

[0027] Under stirring at room temperature, 50 grams of acrylic acid was neutralized with 70 grams of ammonia water, and 5.0 grams of potassium persulfate and 30 grams of deionized water were added and mixed to obtain an aqueous phase. Take 100 grams of the above water phase, and add the water phase under high-speed stirring to the already filled 5 grams of sorbitan monooleate, 0.1 grams of diallyl phthalate, 5 grams of acrylamide, methyl In an oil phase composed of 5 grams of acrylamide, 2 grams of vinylpyrrolidone and 55 grams of kerosene, emulsify at a high speed of 1000 rpm for 30 minutes to obtain a stable pre-emulsion. Under the protection of nitrogen, raise the temperature of the pre-emulsion in the reactor to 50-60°C, the reaction will gradually start, and the temperature of the system will gradually rise. Cooling can be carried out to control the reaction temperature not to exceed 90°C. After 10 minutes of reaction, the temperature will gradually decrease. Keep warm at...

Embodiment 2

[0029] Under stirring at room temperature, 50 grams of methacrylic acid was neutralized with 70 grams of ammonia water, and 8.0 grams of potassium persulfate and 30 grams of deionized water were added and mixed to obtain an aqueous phase. Take 100 grams of the above-mentioned water phase, and add the water phase under high-speed stirring to the already filled 5 grams of sorbitan monostearate, 0.1 grams of divinylbenzene, 7 grams of styrene, and 7 grams of ethyl acrylate. , 2 grams of vinylpyrrolidone and 55 grams of gasoline in the oil phase, emulsified at a high speed of 1000 rpm for 30 minutes to obtain a stable pre-emulsion. Under the protection of nitrogen, raise the temperature of the pre-emulsion in the reactor to 50-60°C, the reaction will gradually start, and the temperature of the system will gradually rise. Cooling can be carried out to control the reaction temperature not to exceed 90°C. After 10 minutes of reaction, the temperature will gradually decrease. Keep war...

Embodiment 3

[0031]Under stirring at room temperature, 20 grams of acrylic acid and 30 grams of maleic acid were neutralized with 80 grams of ammonia water, and 6.5 grams of ammonium persulfate and 35 grams of deionized water were added and mixed to obtain an aqueous phase. Take 100 grams of the above-mentioned water phase, and add the water phase under high-speed stirring to the already filled 5 grams of sorbitan monopalmitate, 0.2 grams of ethylene glycol diacrylate, 10 grams of ethyl methacrylate, acrylic acid In an oil phase composed of 5 grams of butyl ester, 2 grams of vinylpyrrolidone and 55 grams of white oil, emulsify at a high speed of 1200 rpm for 30 minutes to obtain a stable pre-emulsion. Under the protection of nitrogen, raise the temperature of the pre-emulsion in the reactor to 50-60°C, the reaction will gradually start, and the temperature of the system will gradually rise. Cooling can be carried out to control the reaction temperature not to exceed 90°C. After 10 minutes o...

Abstract

The invention discloses a paint thickener for printing and a preparation method thereof. The preparation method comprises the following steps: using unsaturated and acidic monomers, crosslinking agent, unsaturated compound and functional monomers to perform inverse emulsion polymerization in hydrocarbon solvent under the action of initiator and oil-soluble emulsifier and performing inverse emulsion, wherein unsaturated and acidic monomers are neutralized before the polymerization. The paint thickener for printing of the invention has excellent thickening ability and electrolyte tolerance performance, high colour yield and soft hand feeling.

Description

technical field [0001] The invention relates to the field of printing and dyeing auxiliaries, in particular to a pigment printing thickener and a preparation method thereof. Background technique [0002] Pigment printing is a printing method in which finely dispersed pigment particles are attached to fabrics with the help of adhesives. It has the characteristics of simple processing technology, no need for steaming and washing, and less "three wastes". During pigment printing, the pigment printing paste composed of thickener, water, binder and paint, under the action of the scraper of the printing machine, generates shear force on it, so that the viscosity of the printing paste is greatly reduced in an instant , printed on the fabric after passing through the screen, and when the shear force disappears, it returns to the original high viscosity, making the fabric printing outline clear. This viscosity change with the change of the shear force is mainly due to Thickeners are...
