Embodiment 1

[0037] Add 0.2g of wetting agent (k-12) to 48g of ethylene glycol, add 20g of weakly basic carbon black after stirring evenly, stir with an emulsifying machine, and use 29.8g of ethylene glycol for 2g of dispersant (x=10, y=15) Disperse to obtain a dispersant solution, stir the carbon black for 0.5 hours, add the dispersant solution, continue stirring for 0.5 hours, measure pH=8, transfer the material to a vertical sand mill, add 50ml of 0.4-0.6mm zirconium beads, and start sanding , the rotation speed is 1000 rpm, and after 2 hours, the carbon black slurry is obtained after filtering the zirconium beads, and the particle size D of the obtained carbon black colorant material is measured. 95 =88nm, Zeta potential greater than 30, viscosity 245CP, put it at 70℃ and store it for 1 month and then test D 95 =110nm, Zeta potential is greater than 30, viscosity is 305CP, it can be seen that the material is stable, and the 3-month normal temperature storage stability test D is also me...

Embodiment 2

[0039] Add 1.5g wetting agent k-8 to 32.95g ethylene glycol to dissolve, add 0.1 ethanolamine 0.45g to 50g ethylene glycol, stir evenly, add 15g acid carbon black, stir with emulsifier, 2g dispersant (x= 10, y=20) Dissolve with the remaining amount of ethylene glycol, add dispersion liquid after wetting, stir for 1 hour, measure pH=8, transfer the material to a vertical sand mill, add 50ml of 0.4-0.6mm zirconium beads , start sanding, rotate speed 1000 rpm, end after 2 hours, filter zirconium beads to get carbon black slurry, measure particle size D 95 =98nm, Zeta potential greater than 30, viscosity 300CP, placed at 70°C for 1 month after storage, test D 95=105nm, Zeta potential is greater than 30, viscosity is 470CP, it can be seen that the material is stable, and the stability test at room temperature for 3 months is measured at the same time, D 95 = 110nm, Zeta potential greater than 30, viscosity 380cP, storage viscosity 880cP for one year, particle size D 95 = 130nm. ...

Embodiment 3

[0041] Add 0.2g of wetting agent k-10 and 0.6g of ethanolamine to 52.2g of ethylene glycol. After stirring evenly, add 20g of acidic carbon black, stir at low speed for wetting, and add 2.0g of dispersant to 25g of ethylene glycol (x=10 , y=10) to dissolve to obtain a dispersant solution. After the material is completely wetted, add the dispersant solution and stir for a total of 1 hour to measure pH=10. Transfer the material to a vertical sand mill bucket and add 0.4 to 0.6mm zirconium Beads 50ml, start sanding, rotating speed 1000 rev / min, finish after 2 hours, get carbon black slurry after filtering zirconium beads, measure the particle size of carbon black slurry, D 95 ==90nm, Zeta potential greater than 30, viscosity 280CP, stored at 70°C for 1 month and tested D 95 ==110nm, Zeta potential is greater than 30, viscosity is 500CP, it can be seen that the material is stable, and the stability test at room temperature for 3 months is measured at the same time, D 95 ==110nm, ...

Abstract

The invention relates to a carbonarius paste and a preparation method thereof. The carbonarius paste is prepared from, by weight, 15-30% of carbon black, 0.1-1.0% of a wetting agent, 1.5-15% of a dispersing agent, 0.6-3% of a pH adjusting agent and the balance dispersion medium. According to the carbonarius paste, the structure of the dispersing agent is similar to that of the wetting agent, the using concentration of the carbon black is increased, the preparation technology is simple, and the carbonarius paste product higher in concentration and stable in state is obtained.

Description

technical field [0001] The invention relates to carbon black pulp and a preparation method thereof, in particular to a carbon black pulp and a preparation method thereof. Background technique [0002] Polyester fiber is a polyester obtained by polycondensation of dibasic acid and dihydric alcohol. Among the synthetic fibers obtained by melt spinning, polyester fibers are widely used in clothing, military industry, and many other fields, and are the largest output of synthetic fibers. Variety. [0003] Polyester dope dyeing mainly includes chip spinning and polymerization spinning. Because chip spinning has the characteristics of flexibility, easy variety replacement and suitable for masterbatch blended yarn, coupled with the wide application of new high-speed spinning technology, at present, most domestic dye-free polyester filaments are produced by small unit chip spinning process. . [0004] During the main transesterification reaction and polycondensation reaction of p...
