Title
(EN) AN IMPROVED PROCESS FOR THE PRODUCTION OF CARBON BLACK
(FR) PROCÉDÉ AMÉLIORÉ POUR LA PRODUCTION DE NOIR DE CARBONE
Abstract
(EN) A process for producing surface modified carbon black is disclosed. The process comprises the step of treating carbon black with a sulfur compound in an amount in the range of 0.005% - 1 % of the carbon black to effect in situ formation of surface groups to produce the surface modified carbon black which when combined with a polymer composition alters the carbon black-polymer interaction to decrease the hysteresis of the polymer composition. The curing time required for polymer composition comprising the surface modified carbon black is also decreased. The preferred sulfur compounds are sulfite or sulfate salts.
(FR) L'invention concerne un procédé de production de noir de carbone à surface modifiée. Le procédé comprend l'étape de traitement du noir de carbone avec un composé de soufre dans une quantité allant de 0,005% à 1% du noir de carbone pour effectuer la formation in-situ de groupes de surface de manière à produire le noir de carbone à surface modifiée qui, lorsqu'il est mélangé avec une composition de polymère modifie l'interaction noir de carbone-polymère afin de diminuer l'hystérésis de la composition de polymère. En outre, le temps de durcissement requis pour la composition de polymère comprenant le noir de carbone à surface modifiée est inférieur au temps de durcissement requis pour la composition de polymère comprenant le noir de carbone non modifié. La Figure 1 présente la courbe de durcissement A pour la composition de polymère comprenant le noir de carbone non modifié et la courbe de durcissement B de la composition de polymère comprenant le noir de carbone à surface modifiée.
