METHOD FOR MAKING A SELF-SEALING COMPOSITION

摘要

The invention relates to a method for making a self-sealing elastomer composition, wherein said method comprises the following steps: a) first making a master batch including at least one diene elastomer and more than 30 pce of a hydrocarbon resin by mixing these different components in a mixer at or up to a so-called hot-mixing temperature higher than the softening temperature of the hydrocarbon resin; b) then feeding into the master batch thus prepared at least one cross-linking system and mixing the entirety in the same mixer or in a different mixer at a temperature or up to a temperature lower than 100°C in order to obtain said self-sealing composition.
