Abstract

The invention discloses a carbon black modifying technology. The carbon black modifying technology adopts a method with the following steps of dispersing and grinding the carbon black powder into a carbon black color paste; leading ozone micro-nanometer air bubbles into the carbon black color paste, so as to oxidize and modify the carbon black, and enhance the dispersing stability of the carbon black in a water system. A carbon black modifying device is designed for the carbon black modifying technology, and is used for dispersing and grinding the carbon black color paste, and providing the ozone micro-nanometer air bubbles for the carbon black color paste, so as to provide support for the realization of the carbon black modifying technology. The carbon black modifying technology can solvethe technical problems of the traditional carbon black modifying technology that the stability of the dispersing system is low, other byproducts and impurities are easy to entrap, the modifying technology route is longer, the operation is complicated, and the traditional carbon black modifying technology is not suitable for industrialized production.

Description

Technical field [0001] The invention relates to the technical field of carbon black modification, in particular to a carbon black modification process and device. Background technique [0002] Due to the small particles, large specific surface area, and high surface free energy of carbon black, it is easy to form strong agglomeration forces between carbon black ions, making it hydrophobic and difficult to disperse in aqueous systems. At present, there are a variety of industrial carbon black oxidation modification processes to improve the dispersion performance of carbon black in aqueous systems. For example, various dispersants with many hydrophilic groups and water-absorbing groups are used to modify carbon black; another example is to use nitric acid, hydrogen peroxide, hypochlorite and other oxidants to chemically oxidize carbon black. [0003] Although these methods have more obvious oxidation effects on carbon black, the stability of the dispersion of carbon black in aqueous...
