A vulcanizable rubber composition having improved metal adhesion and metal adhesion retention properties with bright steel, the improvement wherein from about 0.1 to about 10 parts by weight of a compound selected from the group consisting of aminosilanes and mercaptosilanes and mixtures thereof, per 100 parts of the rubber component in the rubber composition is incorporated into the rubber composition prior to curing. Structural components for a pneumatic tire contain a cured rubber composition, having from about 0.1 to about 10 parts by weight of a compound selected from the group consisting of aminosilanes and mercaptosilanes and mixtures thereof per 100 parts of the rubber component in the rubber composition, incorporated into the rubber compounds prior to curin. A method for improving metal adhesion and metal adhesion retention properties between a vulcanizable rubber composition and bright steel comprises the step of incorporating from about 0.1 to about 10 parts by weight of a compound selected from the group consisting of aminosilanes and mercaptosilanes and mixtures thereof per 100 parts of the rubber component in the rubber composition into the rubber composition prior to curing.

La présente invention concerne une composition de caoutchouc vulcanisable présentant une meilleure adhésion avec le métal et conservant mieux cette adhésion au métal dans le cas de l'acier brillant. Cette amélioration découle de l'adjonction dans la composition, avant vulcanisation, d'environ 0,1 à environ 10 parties en masse d'un composé prix dans le groupe des aminosilanes, marcaptosilanes et certains de leurs mélanges pour 100 parties de composant caoutchouc dans la composition de caoutchouc. L'invention concerne également des composants structuraux de pneumatiques dans lesquels on a incorporé avant vulcanisation une composition de caoutchouc vulcanisé comportant d'environ 0,1 à environ 10 parties en masse d'un composé pris dans le groupe des aminosilanes et mercaptosilanes ou certains de leurs mélanges pour 100 parties de composant caoutchouc dans la composition de caoutchouc. L'invention concerne enfin un procédé permettant d'améliorer l'adhésion aux métaux et les propriétés de conservation de l'adhésion au métaux entre une composition de caoutchouc vulcanisable et un acier brillant. A cet effet, on incorpore à la composition de caoutchouc avant vulcanisation de 0,1 à 10 parties en masse d'un composé pris dans le groupe des aminosilanes et mercaptosilanes et certains de leurs mélanges pour 100 parties de composant caoutchouc dans la composition de caoutchouc.
