| titleOfInvention | A kind of comb-type disperse dye dispersant and preparation method thereof |
| abstract | The invention provides a comb-type disperse dye dispersant and a preparation method thereof, which has good high temperature and high pressure resistance effect, effectively ensures the stability of dye particles of disperse dyes in the high temperature and high pressure dyeing process, reduces the agglomeration and coagulation of dye particles, and has good System adaptability. Comb-type dispersant dye dispersants include styrene maleic anhydride copolymers, polyethylene glycol ether monoalcohols, cyclic structure-containing alkyl alcohols, modified starches and catalysts. The preparation method includes: under nitrogen protection, adding polyethylene glycol ether monoalcohol and alkyl alcohol containing a cyclic structure, heating to 80-100 DEG C, after completely dissolving, adding styrene maleic anhydride copolymer, and heating up to 120 DEG C ～140 ℃, dissolve completely; add catalyst, heat preservation reaction for 5 to 10 hours; cool to 100～120 ℃, add modified starch, heat preservation reaction for 2 to 3 hours; add water, dilute to solid content of 40～60%, use The sodium hydroxide solution is adjusted to pH 5.0 to 7.0, that is, it is obtained. |
