The invention concerns a sulphur-vulcanisable rubber composition, capable of being used for making tyres, comprising at least a diene elastomer, a reinforcing filler and a coupling agent ensuring the bond between the reinforcing filler and the elastomer. The invention is characterised in that said reinforcing filler consists wholly or partly of a modified carbon black having the following characteristics: (i) it is coated at least partly with an aluminium oxide and/or hydroxide layer; (ii) its specific BET surface ranges between 30 and 400 m?2¿/g; (iii) its average particle size (in volume), marked d¿w?, ranges between 20 and 400 nm; (iv) its deagglomeration rate, marked .alpha., measured by the so-called ultrasound-deagglomeration test, at 10 % of the power of an ultrasound probe of 600 watts, is greater than 1.10?-3¿ µm?-1¿/s.
Composition de caoutchouc vulcanisable au soufre, utilisable pour la fabrication de pneumatiques, comportant au moins un élastomère diénique, une charge renforçante et un agent de couplage assurant la liaison entre la charge renforçante et l'élastomère, caractérisée en ce que ladite charge renforçante est constituée en tout ou partie d'un noir de carbone modifié ayant les caractéristiques suivantes: (i) il est revêtu au moins en partie d'une couche d'oxyde et/ou hydroxyde d'aluminium; (ii) sa surface spécifique BET est comprise entre 30 et 400 m2/g; (iii) sa taille moyenne (en masse) de particules, notée dw, est comprise entre 20 et 400 nm; (iv) sa vitesse de désagglomération, notée .alpha., mesurée au test dit de désagglomération aux ultrasons, à 10 % de puissance d'une sonde ultrasons de 600 watts, est supérieure à 1.10-3 µm-1/s.
