Abstract
The present invention discloses a kind of preparation method of disperse dyes macromolecule dispersing agent, belongs to technical field of textile chemical engineering.The present invention is modified dissaving polymer using naphthoic acid etc. to obtain disperse dyes macromolecule dispersing agent, is had more excellent hydrotropy dispersion effect relative to existing dispersant of disperse dye using the unique molecular structure of dissaving polymer and characteristic.
Description
Technical field
The present invention relates to a kind of preparation methods of disperse dyes macromolecule dispersing agent, belong to technical field of textile chemical engineering.
Background technology
In disperse dyes molecular structure without the water soluble groups such as sulfonic group, carboxylic acid group, so disperse dyes are in water
Dissolubility very little.Disperse dyes need to add a certain amount of dispersant in use, the disperse dyes after dispersant is added in
It is suspended in water with the graininess dispersion of tiny crystals.The dispersant being commonly used has nonionic, anion, cation form
Face activating agent and some low molecules or polymer substance (lignosulfonates etc.).Made by the absorption of dispersant and dye molecule
Dispersant is wrapped up used in dye molecule periphery, since the repulsive interaction between dispersant achievees the purpose that disperse dyes.But
The difference of dye structure, the requirement to dispersant are also that different and single surfactants make the dispersion of disperse dyes
With can change with the change of external condition, dyestuff/dispersant system may be destroyed and cannot keep preferable dispersion
Stability.

In, 3.5% concentrated sulfuric acid (in terms of the quality of hyper-branched polyester) is added in, is heated to 30-40 DEG C, it is molten that superbrnaching end-hydroxy polyester is added dropwise
Liquid reacts 4h, and after reaction through cooling, cooling temperature is 35 DEG C, cools down 3h, and rotary evaporation removes solvent, obtained after being evaporated
Then crude product is dissolved in chloroform by crude product, solution is added dropwise in water, and chloroform layer rotary evaporation removing solvent is obtained
Faint yellow solid is dried in vacuo 15h, obtains macromolecule dispersing agent.
Disperse dyes of the present invention macromolecule dispersing agent has dispersion performance excellent as conventional dispersant, but also
The dispersion of disperse dyes/macromolecule dispersing agent not available for conventional disperse dyestuff can be formed, dispersion stabilization is good.
