Title (EN) RUBBER COMPOUND FOR TYRE PORTIONS
(FR) COMPOSÉ DE CAOUTCHOUC POUR PARTIES DE PNEUMATIQUE
Abstract:
(EN) A rubber compound comprising at least one cross-linkable unsaturated chain polymer base, silica functionalized with amine groups, a silane bonding agent belonging to the class of polysulphide organosilanes and a vulcanization system. The silica functionalized with amine groups is obtained through reaction of the silica with alkanolamine compounds having the general formula HOR1NR2R3 where : R1 is a straight or branched aliphatic chain with a number of carbon atoms ranging from 4 to 12; and R2 and R3, which are equal to or different from one another, are H or (CH2)nCH3, where n is an integer ranging from 0 to 4.
(FR) La présente invention concerne un composé de caoutchouc comprenant au moins une base polymère à chaîne insaturée réticulable, de la silice fonctionnalisée avec des groupes amine, un agent de liaison silane appartenant à la classe des organosilanes polysulfurés et un système de vulcanisation. La silice fonctionnalisée avec des groupes amine est obtenue par réaction de la silice avec des composés alcanolamine ayant la formule générale HOR1NR2R3 où: R1 est une chaîne aliphatique linéaire ou ramifiée comprenant un nombre d'atomes de carbone s'étendant de 4 à 12; et R2 et R3, qui sont identiques ou différents l'un de l'autre, sont H ou (CH2)nCH3, où n est un nombre entier d'une valeur allant de 0 à 4.
