The present invention relates to silica-filled rubber compositions and their method of processing. The rubber compositions contain 10 to 150 phr of a particulate precipitated silica having dispersed thereon a trialkoxysilane of the formula: R1Si (OR2)3 where R1 is independently selected from the group consisting of alkyl radicals having from 1 to 20 carbon atoms and aryl radicals having from 6 to 24 carbon atoms; R2 is an alkyl radical having from 1 to 8 carbon atoms; and wherein said trialkoxysilane is present on said silica at a level ranging from 1 to 20 percent by weight based upon the weight of the silica.
L'invention porte sur des compositions de caoutchouc avec charge de silice, et sur les procédés de traitement. Ces compositions renferment de 10 à 150 phr d'une silice particulaire précipitée, renfermant à l'état dispersé, un trialcoxysilane de formule R1Si (OR2)3 où R1 est choisi indépendamment dans le groupe constitué de radicaux alkyle de 1 à 20 atomes de carbone et de radicaux aryle de 6 à 24 atomes de carbone; R2 est un alkyle de 1 à 8 atomes de carbone; le trialcoxysilane est présent sur la silice à une concentration de 1 à 20 % par rapport au poids de silice.
