example 1

[0084] Preparation of α-Hydroxyalkyl Polyoxyethylene Acrylate

[0085] Add 22 grams of α-hydroxyacrylic acid, 343 grams of fatty alcohol polyoxyethylene ether (such as Pingping plus O) and catalyst: p-toluenesulfonate into a four-necked flask equipped with a stirrer, a thermometer, an oil-water separator and a condenser tube. Acid 0.5 gram, polymerization inhibitor phenol 0.1 gram and 300 gram toluene, carry out esterification reaction under reflux temperature 110 ℃~120 ℃, and strictly control the esterification reaction temperature, when the water yield at the bottom of the oil / water separator is constant, the reaction reaches end. The crude product is obtained, the reactant is purified by anion exchange resin, and the organic solvent is distilled off under reduced pressure to obtain α-hydroxyalkyl polyoxyethylene acrylate.

[0087] Preparation of α-Hydroxyalkyl Polyoxyethylene Acrylate

[0088] Add 25 grams of α-hydroxyacrylic acid, 360 grams of fatty alcohol polyoxyethylene ether (such as W-400 produced by Henkel, Germany), and 0.3 grams of water into a four-necked flask equipped with a stirrer, a thermometer, an oil-water separator, and a condenser tube. Acetic anhydride as a catalyst, 0.2 grams of p-cresol as a polymerization inhibitor and 350 grams of cyclohexane as a solvent, carry out esterification reaction at a reflux temperature of 80-90 ° C, and strictly control the esterification reaction temperature, and wait for oil / water separation When the amount of water at the bottom of the vessel is constant, the reaction reaches the end. The crude product is obtained, the reactant is purified by anion exchange resin, and the organic solvent is distilled off under reduced pressure to obtain α-hydroxyalkyl polyoxyethylene acrylate.

Abstract

This invention discloses an ionization resistant, impervious composite printing thickener and its manufacturing method and application, which is got through co polymerization of such unsaturated acids as a-alkyl acrylic acid polyoxyethylene ester, acrylic acid, methacrylic acid and such unsaturated monomers as acrylamide and butyl acrylate in mixed solution of water and solvent naphtha by antiphase latex. When the thickener in this invention is applied in pigment printing color paste, it assumes advantages of high thickening ability, strong ionization resistance and no oozing, and besides it can be applied in thickening white coat, black coat and color paste, the prepared printing color paste not oozing or gelling.

Description

1. Field of invention [0001] The present invention relates to a synthetic thickener, more particularly to an electrolyte-resistant, impervious synthetic printing thickener and its preparation method and application 2. Background technology [0002] For the thickening of textile printing pastes, natural starch and sodium alginate were mainly used initially. With the application of paints on textiles and the continuous manifestation of their advantages, synthetic thickeners have been extensively studied for the thickening of pigment printing. And use, its synthesis method is mostly obtained by inverse emulsion polymerization of monomers such as acrylic acid in hydrocarbon organic solvents and water. This kind of thickener has the advantages of high color yield and relatively low solid content when used for thickening pigment printing, but it has poor electrolyte resistance, poor anti-bleeding ability, easy bleeding, and cannot be used for black and white. Coatings; defects su...
