Embodiment 1-1~ Embodiment 1-7
[0280] According to the composition shown in Table 1-1, put NMP and various polyvinyl alcohols into glass bottles, mix and dissolve thoroughly, or add various carbon blacks after mixing and dispersing, and use 1.25mmφ zirconia beads as the medium, Dispersion was carried out for 2 hours using a paint shaker to obtain each carbon black dispersion liquid. All of them have low viscosity and small D50 value and good storage stability. In addition, it was found that the presence or absence of modification of polyvinyl alcohol does not have a great influence on the performance as a dispersant.
Embodiment 1-8~ Embodiment 1-24
[0285] According to the composition shown in Table 1-1, put NMP and polyvinyl alcohol into a glass bottle, fully mix and dissolve, or after mixing and dispersing, add various carbon blacks, use 1.25mmφ zirconia beads as the medium, and use paint The dispersion was carried out with a shaker for 2 hours to obtain each carbon black dispersion liquid. All of them have low viscosity and small D50 value and good storage stability.
[0286] [Comparative Example 1-3, Reference Example 1-1]
[0287] According to the composition shown in Table 1-1, put NMP and polyvinyl alcohol into a glass bottle, fully mix and dissolve, or after mixing and dispersing, add various carbon blacks, use 1.25mmφ zirconia beads as the medium, and use paint The dispersion was carried out with a shaker for 2 hours to obtain each carbon black dispersion liquid. The obtained dispersion liquids were all in a state of remarkably high viscosity and a large D50 value, so that the carbon black could not be sufficie...
Embodiment 2-1~ Embodiment 2-16
[0290] According to the composition shown in Table 1-2, put NMP, various polyvinyl alcohols and various adhesives into glass bottles, mix and dissolve thoroughly, or add various carbon blacks after mixing and dispersing, and use a homogenizer Dispersion was carried out for 1 hour to obtain each carbon black dispersion liquid. All of them have no coarse particles, have low viscosity, and have good storage stability.
