Abstract
PURPOSE: To prepare the titled carbon black (CB) having low tendency of screen clogging, by sieving an aqueous suspension of CB with a vibrating sieve to separate the grits, adding an organic solvent to the suspension to transfer the CB to the organic phase, and removing water and the solvent from the organic phase.
CONSTITUTION: A homogeneous suspension of CB in water, having a viscosity of 1W100 poise, is sieved with a vibrating sieve having a vibration frequency of 1,500W3,000sec-1 and a vibration amplitude of 1W7mm to remove the grits from the suspension. The sieved suspension is mixed with an organic solvent such as toluene to form an organic solvent phase and an aqueous phase. CB is transferred from the aqueous phase to the organic solvent phase by agitating the system. Finally, water and the organic solvent is removed from the system to obtain the objective CB.
EFFECT: The surface qualities of the molded article obtained by kneading and extruding resin or rubber containing the CB, are remarkably improved.
