Title (EN) COMPOSITION BASED ON NATURAL RUBBER AND A REINFORCING INORGANIC FILLER COMPRISING A DIHYDRAZIDE
(FR) COMPOSITION A BASE DE CAOUTCHOUC NATUREL ET D'UNE CHARGE INORGANIQUE RENFORCANTE COMPRENANT UN DIHYDRAZIDE
Abstract:
(EN) Reinforced rubber composition based on at least: (a) an elastomeric matrix predominantly based on natural rubber; (b) a reinforcing filler predominantly based on an inorganic filler; (c) a coupling agent; and (d) a dihydrazide compound satisfying the following formula (I), in which R is a divalent hydrocarbon radical chosen from aromatic radicals having 6 to 20 carbon atoms and saturated or unsaturated aliphatic radicals having 2 to 20 carbon atoms; and n is equal to 0 or 1. This rubber composition is intended for example for the manufacture of a semi-finished rubber product for making motor vehicle tyres.
(FR) Composition de caoutchouc renforcée à base d'au moins (a) une matrice élastomérique majoritairement à base de caoutchouc naturel, (b) une charge renforçante majoritairement à base d'une charge inorganique, (c) un agent de couplage et (d) un composé dihydrazide répondant à la formule (I) suivante: dans laquelle R est un radical hydrocarboné bivalent choisi parmi les radicaux aromatiques ayant 6 à 20 atomes de carbone, les radicaux aliphatiques, saturés ou insaturés, ayant 2 et 20 atomes de carbone, et n vaut 0 ou 1. Cette composition de caoutchouc est destinée par exemple à la fabrication d'un produit semi- fini en caoutchouc destiné au pneumatique de véhicules automobiles.
