Description
Technical Field
The invention belongs to the technical field of color paste additives, and relates to a water-soluble dispersing agent, a preparation method and application thereof.
Background
The disperse dye is a dye with smaller molecules and no water-soluble groups on the structure, has complete color spectrum, and the dyed product has bright color and excellent indexes, so the disperse dye is widely applied to dyeing of various synthetic fibers, acetate fibers and blended fabrics. It is necessary to disperse the dye uniformly in the dye liquor by means of the dispersing agent during dyeing to dye the fiber such as polyester.
With the rapid development of the industrial printing and dyeing industry in China, the wastewater discharge and pollution degree in the printing and dyeing industry are greatly increased, and the diversification of printing and dyeing products also makes the components in the printing and dyeing wastewater more complex and the treatment more difficult. The traditional disperse dye is added with a large amount of lignin salt, naphthalene sulfonate and other dispersing aids during dispersion, so that the grinding efficiency in the production process is low, the addition amount of the dispersing agent is between 70 and 150 percent of that of the dye, and the high-proportion dispersing agent causes that the printing and dyeing wastewater contains a large amount of organic matters, the treatment process is complicated and has great harm to the environment; and the liquid disperse dyeing paddle is short in stability period and difficult to store for a long time, and the liquid disperse dyeing paddle is required to be sprayed to dry, so that the existing commercial dye in the market is prepared to improve the storage time of the commercial dye.
CN114644762a discloses a multiple modified lignin dye dispersant and a preparation method thereof, industrial alkali lignin is used as a raw material, a sulfonating reagent 1 and a sulfonating reagent 2 are used as a sulfonating reagent system under an alkaline condition, and sulfonic acid groups are simultaneously introduced at different positions, so that the content of hydrophilic group sulfonic acid groups can be greatly improved. Then selectively adding a blocking reagent to reduce the residual hydroxyl content and simultaneously increase the molecular weight. The multi-modified lignin sulfonate can be applied to dye dispersants, can be prepared into a disperse dye system with good dispersibility and excellent high-temperature stability without grinding, has extremely low staining property, has low reduction rate for diazo dye, can obviously improve the dye uptake, and can greatly reduce the production cost of the printing and dyeing industry. However, when the dispersing agent is used for dispersing dye, the adding proportion is higher, and the particle size of the color paste is still larger.
Accordingly, it is desirable in the art to develop a water-soluble dispersant for dye dispersion.

Test case
Adding a dispersing agent, water and disperse dye (disperse blue 79 dye) in sequence according to the proportion by adopting a laboratory sanding mode, wherein the total amount of the slurry formula is 200 g; after stirring evenly, 400g of zirconium beads with the particle size of 0.8-1mm are added and sealed in a glass tank, and the mixture is vibrated for 12 hours and filtered to obtain color paste.
The specific formula of the color paste prepared by the invention is shown in table 1:
TABLE 1
Performance testing
(1) Viscosity: the measurement was performed using an NDJ-1B rotational viscometer, shanghai Changji geological instruments Co., ltd; wherein "-" indicates that the viscosity is too great to measure;
(2) Particle size: testing with BT-90 laser particle sizer, available from Dandong Baite instruments; wherein "\" represents precipitation or no fluidity, and cannot be tested;
(3) Storage stability: storing at 55deg.C for 7 days, observing color paste state, and retesting particle diameter and viscosity;
(4) Centrifugal precipitation rate (%): centrifuging the dye color paste for 20 minutes at 4000 rpm, washing with absolute ethyl alcohol, and baking at 90 ℃ to constant weight, and precisely weighing the precipitate weight; precipitation rate = precipitation weight ≡ (color paste dye content x sample size) ×100%; wherein "+" indicates no flowability and no testing.
The specific test results are shown in table 2:
TABLE 2
As can be seen from Table 2, the water-soluble dispersing agent prepared by compounding the polyether modified polymer A and the polyamide high-molecular polymer B has good dispersing effect (particle size D50 (initial): 189-234 nm) on dye color paste on the premise of small dosage, the viscosity of the color paste can meet the requirement (viscosity (initial): 98-125 mpa.s), the centrifugal precipitation rate is low (0.6% -2.3%), the color paste stability is good (the viscosity and the particle size of the color paste are not greatly changed when the color paste is stored at 55 ℃ for 7 days), and the storage period is long, thereby being superior to the commercially available dispersing agent.
As is clear from the comparison between the test examples 7 and 1, if the addition amount of the reactive macromonomer polyether is too small, the viscosity, the particle size and the centrifugal precipitation rate of the dye paste are greatly increased, and the stability is poor; as is clear from the comparison between test example 8 and test example 3, too much addition of the reactive macromer polyether leads to a significant increase in the viscosity, particle size and centrifugal precipitation rate of the dye paste.
As is clear from the comparison of the comparative test examples 1 to 5 with the test example 1, if any one of the preparation raw materials (vinylbenzene monomer, vinylsulfonic acid monomer and active macromonomer polyether) of the polyether modified polymer A is replaced with other components, or the polyamide high-molecular polymer B is replaced with other components, the viscosity, the particle size and the centrifugal precipitation rate of the dye color paste are obviously increased.
