RUBBER COMPOSITION THAT CAN BE USED FOR MANUFACTURING A TYRE OF WHICH THE COMPOSITION COMPRISES A STARCH AND AN AQUEOUS OR WATER-SOLUBLE PLASTICIZER

摘要

The invention relates to a rubber composition based on at least one diene elastomer, a crosslinking system and a reinforcing filler, characterized in that the composition also comprises a starch in a proportion of from 10 to 50 phr (parts by weight per hundred parts of elastomer) and an aqueous or water-soluble plasticizer in a proportion of from 3 to 30 phr, said aqueous or water-soluble plasticizer being water, or a mixture of water and glycerol in which the water is predominant by weight in the aqueous or water-soluble plasticizer. The invention also relates to a method for obtaining such a composition. The composition according to the invention can be used for preparing calendered or profiled products which are part of the manufacture of a tyre, such as, for example, a tyre tread.
