Problems solved by technology

At present, such thickeners at home and abroad, such as BASF's HIT thickener and Demei's DM-5622 thickener, have poor water holding capacity when used in pigment printing, resulting in poor outline definition of printed fabrics; electrolyte resistance The ability is poor, the specific performance is that after thickening with thickener and water, adding adhesive, paint color paste, etc. to make the printing paste thinner and affect the printing effect; the printed fabric feel, color brightness, etc. are not ideal

Abstract

The present invention is one kind of emulsified acrylate thickener for paint printing. It consists of acrylic acid 160-170 weight portions, vinyl benzene sulfonic acid 90-95 weight portions, 2-acrylamido-2-methypropyl sulfonic acid 18-19 weight portions, chlorotrimethylamino propyl acrylamide 22-24 weight portions, 20 % concentration ammonia water 300-320 weight portions, glyceryl dimethcrylate 2.5-3.5 weight portions, No. 200 solvent oil or aviation kerosene 100-150 weight portions, hydrogenated polyoxyethylene castor oil ether 22-28 weight portions, and ammonium persulfate 5-7 weight portions, which are reverse emulsion polymerized and mixed with linear organosilicon body in 4-6 weight portions. It has high water combining capacity, great electrolysis capacity, good handle and high color brightness.

Description

Technical field [0001] The invention relates to a thickener for textile printing and a preparation method, especially a thickener for pigment printing. Background technique [0002] In textile printing, the thickener only serves to carry dyes and pigments. In dye printing, the thickener must be washed off the fabric eventually; while pigment printing does not require washing, this type of thickener is required, whether it is in It can be used in paint printing because it has excellent environmental performance, color vividness, hand feeling and outline clarity. At present, such thickeners at home and abroad, such as BASF's HIT thickener and Demei's DM-5622 thickener, have poor water holding capacity for pigment printing, which makes the printed fabric contour poorly clear; electrolyte resistance Poor ability, which is specifically manifested in that after thickening with a thickener and water, adding adhesives, paint pastes, etc. to make the printing paste thinner and affect the ...
