Abstract

The invention discloses an electrolyte-resistant pigment printing thickener, belongs to the technical field of textile dyeing and printing auxiliaries, and aims to solve the problem of poor electrolyte resistance and thickening effect coordination of the conventional printing acrylic acid synthetic thickener. The electrolyte-resistant pigment printing thickener is obtained by neutralizing an acrylic acid monomer with a pH conditioner, adding an initiator ammonium persulfate and a crosslinking agent to prepare an aqueous phase, carrying out pre-emulsification the aqueous phase and an oil phase prepared from an oil-phase solvent, an initiator, an emulsifier and a comonomer, further performing complete emulsification under the action of an initiator sodium bisulfite, finally adding a reversed-phase emulsifier for complete reversed-phase emulsification and performing discharging and drying. The prepared electrolyte-resistant pigment printing thickener has high thickening performance and electrolyte resistance, and is simple in preparation process and easy to be industrially produced.

Description

technical field [0001] The invention relates to a thickener, in particular to an electrolyte-resistant pigment printing thickener. 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, 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 achieved. [0003] Patent CN103450423B utiliz...
