  • Publication number: 20180037760
    Abstract: Provided is a method for conveniently producing a water dispersion of oxidized carbon black particles that exhibits excellent dispersibility and storage stability, in the case of producing a water dispersion of oxidized carbon black particles by liquid-phase oxidation of carbon black particles using a persulfate. In the method for producing a water dispersion of oxidized carbon black particles by bringing at least one persulfate and carbon black particles into contact to perform liquid-phase oxidation, in the presence of an inorganic alkali in an amount equal to or greater than an amount theoretically necessary for neutralizing an acidic product produced by the liquid-phase oxidation, the persulfate and the carbon black particles are brought into contact in water and subjected to liquid-phase oxidation treatment while being heated.

  • Patent number: 8026319
    Abstract: Dispersible surface-modified carbon black that is surface-modified by causing a functional group on the surface of the carbon black to be bonded to a diol-modified end-containing polymer through a triisocyanate compound exhibits excellent dispersibility in a non-polar solvent, a low-polar solvent, and a resin. The dispersible surface-modified carbon black is characterized in that a surface functional group of the carbon black is bonded to one isocyanate end group of a triisocyanate compound having three isocyanate end groups, and the remaining two isocyanate end groups are respectively bonded to hydroxyl groups of a diol-modified end-containing polymer.

  • Publication number: 20090137731
    Abstract: Surface-modified carbon black which exhibits excellent dispersibility in a silicone oil (non-polar medium) and a dispersion of the surface-modified carbon black are disclosed. The surface-modified carbon black includes an isocyanate compound having isocyanate groups on both ends and chemically bonded to a functional group on the surface of the carbon black, the isocyanate compound being chemically bonded to a reactive silicone polymer. The surface-modified carbon black dispersion is produced by dissolving an isocyanate compound having isocyanate groups on both ends in a solvent, adding carbon black to the solution, mixing the components so that one of the isocyanate groups is bonded to the surface of the carbon black via a urethane bond, removing an unreacted isocyanate compound, dispersing the carbon black in a silicone oil, and adding a reactive silicone polymer to the dispersion, followed by mixing and deaeration.
