Embodiment 1

[0038] Under stirring at room temperature, 50 grams of acrylic acid was neutralized with 70 grams of liquid caustic soda, and 5.0 grams of potassium persulfate and 30 grams of deionized water were added and mixed to obtain a water phase. Take 100 grams of the above water phase, and add the water phase to 5 grams of sorbitan monooleate, 0.1 grams of diallyl phthalate, 5 grams of acrylamide, and methacrylamide under high-speed stirring. 5 grams, 3 grams of vinyl silicone oil, 1 gram of methacryloyloxyethyltrimethylammonium chloride, 3 grams of lauryl methacrylate and 55 grams of kerosene in the oil phase, high-speed 1000 rpm emulsification 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 react...

Embodiment 2

[0040] Under stirring at room temperature, 50 grams of methacrylic acid was neutralized with 70 grams of liquid caustic soda, 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 to 5 grams of sorbitan monostearate, 0.1 gram of divinylbenzene, 7 grams of styrene, 7 grams of ethyl acrylate, ethylene under high-speed stirring. In the oil phase composed of 4 grams of base silicone oil, 2 grams of methacryloyloxyethyltrimethylammonium chloride, 3 grams of myristyl methacrylate and 55 grams of gasoline, emulsify at a high speed of 1000 rpm for 30 minutes to obtain 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 ...

Embodiment 3

[0042] Under stirring at room temperature, 20 grams of acrylic acid and 30 grams of maleic acid were neutralized with 80 grams of liquid caustic soda, 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 the oil phase composed of 5 grams of butyl ester, 5 grams of vinyl silicone oil, 3 grams of methacryloyloxyethyltrimethylammonium chloride, 3 grams of cetyl methacrylate and 55 grams of white oil, the high speed is 1200 rpm Separate emulsification 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 gr...

Abstract

The invention discloses a disperse printing thickener and a preparation method thereof. The current disperse printing thickener has the disadvantages of not ideal thickening effect, poor electrolyte tolerance ability and poor feel. The disperse printing thickener provided by the invention is prepared through inverse emulsion polymerization and reversed phase emulsion of an unsaturated acid monomer, a crosslinking agent, a soft monomer and a salt tolerance substance in a hydrocarbon solvent under the action of an initiator, an oil-soluble emulsifier and a phase inversion agent. The salt tolerance substance is one or any mixture of two or more kinds of associative monomer, cationic monomer and an unsaturated compound. The disperse printing thickener prepared by the method provided by the invention has the advantages of excellent thickening ability, anti-electrolyte performance, high color yield and soft feel.

Description

technical field [0001] The invention relates to the field of printing and dyeing auxiliaries, in particular to a dispersed printing thickener and a preparation method thereof. Background technique [0002] Polyester is the largest and most widely used synthetic fiber variety in the world. At present, polyester accounts for more than 60% of the world's synthetic fiber output, and is widely used in textiles such as clothing, bedding, various decorative fabrics, and special fabrics for national defense and military industries. Disperse printing (full name is direct printing with disperse dyes), mainly involves pure polyester printing products, including polyester silk and polyester knitted fabrics, which have the advantages of crispness, smoothness, quick drying and durability, and are widely welcomed by the market. [0003] There are many types of thickeners (pastes) for disperse printing, with large consumption, great price differences and different performances. Their import...
