OXIDIZED WET BEADED CARBON BLACK

The present invention relates to a process for the production of oxidized wet beaded carbon black. It has been found that carbon black can be wet beaded and oxidized subsequently. This process allows a better control of the degree of oxidation without damaging the beads. Moreover, the oxidized wet b...

Zusammenfassung:	The present invention relates to a process for the production of oxidized wet beaded carbon black. It has been found that carbon black can be wet beaded and oxidized subsequently. This process allows a better control of the degree of oxidation without damaging the beads. Moreover, the oxidized wet beaded carbon black can be beneficially used in a rubber composition to increase the properties of the resulting rubber product.. La présente invention concerne un processus pour la production de noir de carbone perlé à l'humidité oxydé. Il a été découvert que le noir de carbone peut être perlé à l'humidité et oxydé par la suite. Le processus selon l'invention permet une meilleure maîtrise du degré d'oxydation sans endommager les billes. De plus, le noir de carbone perlé à l'humidité oxydé peut être utilisé avantageusement dans une composition de caoutchouc pour augmenter les propriétés du produit de caoutchouc obtenu.
