Abstract
A rubber composition intended for the manufacture of tire casings and elastic bearings for vehicle suspension systems, with elastomeric base containing oxygenated functions reinforced with a majority of silica-type filler, whose hysteretic properties are improved by use of a combination of an aminoalkylalkoxysilane with an alkylalkoxysilane, particularly for use in the tread of tire casings for trucks, construction and farm vehicles or airplanes.
Claims19
A rubber composition comprising:
- a) at least one diene elastomer having oxygenated functions;
- b) a filler containing, at least in part, at least one so-called “silica-type” material selected from the group consisting of the silicas and the materials other than silicas possessing on the surface oxygenated functions of silicon;
- c) at least one coupling agent selected from the group consisting of aminoalkyalkoxysilanes, aminoarylalkoxysilanes and aminoaralkyalkoxysilanes, the alkyl, aryl or aralkyl groups can, optionally, be substituted by functional groups;
- d) at least one covering agent selected from the group consisting of alkylalkoxysilanes, arylalkoxysilanes and aralkylalkoxysilanes, the alkyl, aryl or aralkyl groups can, optionally, be substituted by functional groups, except amino or sulfo groups.
