Method for rapidly dispersing conductive carbon black

Abstract

The invention relates to a method for rapidly dispersing conductive carbon black. The method comprises the steps of adding a certain amount of conductive carbon black to a container,and adding a hot solution to the conductive carbon black; dispersing the conductive carbon black in the hot solution by a physical dispersion method,adding chemical additives simultaneously,and stirring and mixing thesolution and the chemical additives uniformly to finally obtain a uniform and stable conductive carbon black dispersion. The method combines physical and chemical dispersion to rapidly dissolve and disperse the conductive carbon black in a normal pressure vaporized molecular atmosphere,vaporize small molecules are separated among conductive carbon black aggregates,the distance during the vaporization processes is sharply increased to generate large expansion force which destroys the van der Waals force of the conductive carbon black aggregate,depolymerization is achieved,and the conductive carbon black is subjected to stabilization treatment by adding the chemical additives,thereby finally achieving the rapid dissolution and uniform dispersion of the conductive carbon black. The method caneffectively inhibit the agglomeration of the conductive carbon black and improve the dispersibility and stability of the conductive carbon black in a medium.

Description

technical field [0001] The invention relates to a method for quickly dispersing conductive carbon black, which belongs to the technical field of new materials. Background technique [0002] Conductive carbon black has the characteristics of high conductivity, high structural properties, irregular aggregates and very small size (nanoscale), large and rough specific surface area, clean surface (less compounds), and easy mixing with other materials. It can be effectively Form a three-dimensional network structure in the insulator, effectively improve the conductivity, and can endow the product with conductivity or antistatic effect. Conductive carbon black is the product with the best effect, the lowest cost, and the least likely to cause deterioration of the physical properties of the product among all conductive fillers. Conductive carbon black can be divided into conductive channel black (cc), conductive furnace carbon black (CF), superconductive furnace carbon black (SCF),...
