Abstract

The invention discloses a polymeric dispersing agent for textile dyes and a preparation method of the polymeric dispersing agent in the technical field of fine chemical engineering. The preparation method of the polymeric dispersing agent for the textile dyes comprises the following steps that step 1, 10-30 parts of butyl methacrylate is added into a reactor of 60-80 DEG C; step 2, 4-6 parts of acrylic acid and 1 part of butyl methacrylate are mixed and added into another dropping funnel, an initiator is added, a reaction is performed for 2 hours; 4-6 parts of titanium sulphate is put into thereactor, the initiator is poured into the reactor through the funnel and is slowly stirred; step 3, substances after the reaction is evaporated to obtain a solid substance, the solid substance is added into the reactor, and 20-60 parts of water is added to form an aqueous solution; through stearamide and higher alcohols which are added in the prepared materials, while the own molecular activity is improved, the molecular stability of the butyl methacrylate in the mixed solution is also improved.

Description

technical field [0001] The invention relates to the technical field of fine chemicals, in particular to a polymer dispersant for textile dyes and a preparation method thereof. Background technique [0002] Dyes refer to a class of organic compounds that can make other substances obtain bright and firm colors. Since the pigments used today are all artificially synthesized, they are also called synthetic dyes. Dyes and pigments are generally self-colored compounds that can make other substances obtain bright and firm colors in molecular or dispersed state. [0003] Disperse dyes are a kind of dyes. Disperse dyes are a kind of dyes with relatively small molecules and no water-soluble groups in their structure. It must be dyed with the aid of a dispersant to disperse the dye evenly in the dye solution in order to dye fibers such as polyester. The disperse dye molecule contains polar groups, but does not contain sulfonic acid groups and carboxylic acid groups. Water-soluble gro...
