Abstract
L'invention concerne un pneumatique pour véhicule. Il est prévu dans le pneumatique une couche intérieure caoutchoutée formée d'un caoutchouc collant à la confection et d'un copolymère de styrène-butadiène, la teneur en styrène lié dans une molécule du mélange composite s'élevant à au moins 15 parties en poids pour 100 parties de caoutchouc; il est ainsi possible d'obtenir une faible perméabilité aux gaz et une résistance mécanique suffisante pour la couche intérieure caoutchoutée; la fabrication du pneumatique, qui comporte une couche intérieure formée d'un mélange caoutchouté réticulé préalablement ou partiellement, est possible par un processus de vulcanisation sans vessie de chauffage, ce qui permet de réduire les frais de fabrication.The invention relates to a tire for a vehicle. There is provided in the tire a rubberized inner layer formed of a rubber sticky to the construction and of a styrene-butadiene copolymer, the content of styrene bound in one molecule of the composite mixture amounting to at least 15 parts by weight. per 100 parts of rubber; it is thus possible to obtain a low permeability to gases and a sufficient mechanical strength for the rubberized inner layer; the manufacture of the tire, which comprises an inner layer formed from a rubberized mixture crosslinked beforehand or partially, is possible by a vulcanization process without a heating bladder, which makes it possible to reduce the manufacturing costs.
