Title (EN) TYRE COMPONENT NOT IN CONTACT WITH AIR, BASED ON NATURAL RUBBER, A REINFORCING FILLER AND A DIHYDRAZIDE
(FR) COMPOSANT DE PNEUMATIQUE SANS CONTACT AVEC L'AIR A BASE DE CAOUTCHOUC NATUREL, D'UNE CHARGE RENFORCANTE ET D'UN DIHYDRAZIDE
Abstract:
(EN) Tyre component which is not in contact with air or with an inflation gas, comprising a rubber composition based on: (a) an elastomeric matrix based on natural rubber; (b) a reinforcing filler; (c) more than 2.5 to 8.5 phr sulphur; and (d) a dihydrazide compound satisfying the following formula (I): in which R is a divalent hydrocarbon radical chosen from substituted or unsubstituted aromatic radicals having 6 to 20 carbon atoms, and saturated or unsaturated, linear or branched, aliphatic radicals having 2 to 20 carbon atoms; and n is equal to 0 or 1. These tyre components are more particularly those that comprise reinforcing threads, especially metal threads, such as carcass plies or crowned plies for tyres.
(FR) Composant du pneumatique qui n'est pas en contact avec l'air ou avec un gaz de gonflage, comprenant une composition de caoutchouc à base de (a) une matrice élastomérique à base de caoutchouc naturel, (b) une charge renforçante, (c) plus de 2,5 à 8,5 pce de soufre et (d) un composé dihydrazide répondant à la formule suivante: (I) dans laquelle R est un radical hydrocarboné bivalent choisi parmi les radicaux aromatiques substitués ou non, ayant 6 à 20 atomes de carbone, les radicaux aliphatiques, saturés ou insaturés, linéaires ou ramifiés, ayant 2 et 20 atomes de carbone, et n vaut 0 ou 1. Ces composants du pneumatique sont plus particulièrement ceux qui comprennent des éléments de renfort filaires, plus spécialement métalliques, tels que les nappes carcasse ou sommet du pneumatique.
