Title (EN) PROCESS FOR PRODUCING MODIFIED CARBON BLACK FOR REINFORCING RUBBER AND PROCESS FOR PRODUCING RUBBER COMPOSITION CONTAINING MODIFIED CARBON BLACK
(FR) PROCEDE POUR PRODUIRE DU NOIR DE CARBONE MODIFIE ET DESTINE A RENFORCER DU CAOUTCHOUC, ET PROCEDE POUR PRODUIRE UNE COMPOSITION DE CAOUTCHOUC CONTENANT CE NOIR DE CARBONE MODIFIE
Abstract:
(EN) A process for producing a modified carbon black for reinforcing rubber, which retains the excellent temperature dependence of tan $g(d) inherent in silica and a good abrasion resistance and is freed from the problems caused by a low electric conductivity at a low cost. More specifically, a process for producing a modified carbon black for reinforcing rubber, wherein a water-dispersible silica is added to a carbon black and the resultant mixture is granulated with a granulator in the step of granulating the carbon black; and a process for producing a rubber composition containing a surface-treated carbon black for reinforcing rubber, wherein (a) 100 parts by weight (in terms of solid) of a latex prepared from a diene rubber component are mixed with (b) 10 to 250 parts by weight (in terms of solid) of a slurry containing the water-dispersible silica and the carbon black for reinforcing rubber or (b') 10 to 250 parts by weight of the modified carbon black prepared by the above-described process, and then the mixture is solidified with a solidifier.
(FR) L'invention concerne un procédé pour produire du noir de carbone modifié et destiné à renforcer du caoutchouc qui conserve l'excellente variabilité thermique du facteur de dissipation inhérente à la silice et une bonne résistance à l'abrasion et ne présente pas les problèmes dus à une faible conductivité électrique, et ce, pour un faible coût. Plus précisement, l'invention concerne un procédé pour produire un noir de carbone modifié et destiné à renforcer du caoutchouc, dans lequel une silice hydrodispersible est ajoutée à un noir de carbone et le mélange obtenu est granulé à l'aide d'un granulateur lors de l'étape de granulation du noir de carbone. Elle concerne d'autre part un procédé pour produire une composition de caoutchouc contenant un noir de carbone ayant subi un traitement de surface et destiné à renforcer du caoutchouc, procédé dans lequel: a) 100 parties en poids (exprimées sous forme de solide) d'un latex préparé à partir d'un constituant caoutchouc diène sont mélangées avec (b) 10 à 250 parties en poids (exprimées sous forme de solide) d'une boue contenant la silice hydrodispersible et le noir de carbone ou (b') 10 à 250 parties en poids du noir de carbone modifié préparé à l'aide du procédé précité, et le mélange est ensuite solidifié avec un solidifiant.
