Abstract

The invention discloses a preparation method for synthesizing a thickening agent by acrylic ester. The thickening agent synthesized by acrylic ester comprises crylic acid, acrylamide, 25 percent of ammonia water, a functional monomer, EDTA, deionized water, tasteless kerosene, 3<#> white oil, diallyl phthalate, ammonium persulphate, Span 80 and isomeric hexadecanol polyethenoxy ether, wherein the functional monomer is prepared from alicyclic amine polyethenoxy ether, methyl methacrylate, nitroxide free radical pipradrol and sodium methoxide. The preparation method synthesizes a special weak cation type (methyl) acrylic ester functional monomer by adopting an ester exchange method, and the functional monomer and vinyl monomers of the acrylic acid, the acrylamide, and the like are adopted to synthesize a textile printing thickening agent by adopting inverse emulsion polymerization. The thickening agent has the characteristics of high thickening capacity, strong electrolyte resistant capacity and good water-retaining property.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to an acrylate synthetic thickener and a preparation method thereof. Background technique [0002] In textile printing, the pigment printing paste composed of thickener, water, binder and paint, or the dye printing paste composed of thickener, water, and dyes, under the action of the scraper of the printing machine, The shearing force is generated, so that the viscosity of the printing paste is greatly reduced in an instant, and it is printed on the fabric after passing through the screen. When the shearing 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 realized by the thickener. [0003] Thickeners in the printing process, in addition to requiring high thickening ability and electrolyte resistance to reduce dosage, reduce costs, and reduce the impact...
