preparation example Construction
[0038] The preparation method that embodiment and comparative example adopt is:
[0039] a) Reserving 10-20% of the total mass of deionized water, mixing and dispersing the remaining deionized water, dispersant A, dispersant B, wetting agent, and moisturizing agent in disperser 1 to obtain a premixed liquid;
[0040] b) Add carbon nanotubes to the premixed solution obtained in step a) for dispersion, use disperser 1 to disperse at a speed higher than 200 rpm for no less than 30 minutes, and add the premixed solution in step a) during the dispersion process Stay deionized water to obtain pre-dispersed carbon nanotube slurry;
[0041] c) The first delivery pump 2 grinds and disperses the pre-dispersed carbon nanotube slurry obtained in step b) in the grinder 3 for 3-10 times, and the second delivery pump 4 sends it to the ultrasonic dispersion device 5 for ultrasonic dispersion treatment After 0.5-2 hours to obtain the water-based carbon nanotube slurry, the third delivery pump...
Embodiment 1
[0057] Reserve 10 parts of deionized water, disperse 68.82 parts of deionized water, 3 parts of dispersant A1, 1.8 parts of dispersant B1, 0.18 parts of phosphatidylcholine, and 10 parts of ethylene glycol in a disperser to obtain a premixed solution; Add 6 parts of multi-walled carbon nanotubes into the premixed solution for dispersion, use a disperser to disperse for 40 minutes at a speed of 600 rpm, and add 10 parts of deionized water reserved during the dispersion process to obtain pre-dispersed carbon nanotubes Tube slurry; grind and disperse the pre-dispersed carbon nanotube slurry in a grinder for 8 times, add 0.2 parts of polysiloxane ether copolymer during the grinding process, and then perform ultrasonic dispersion treatment for 1 hour to obtain water-based carbon nanotubes slurry.
