| abstract | A method for producing a masterbatch comprising a diene elastomer, an organic reinforcing filler and, optionally, an antioxidant. The invention relates to a method for producing a masterbatch comprising a diene elastomer and a reinforcing filler, the dispersion of the reinforcing filler in the elastomer matrix having a Z score greater than or equal to 80, and said diene elastomer comprising at least natural rubber. The method comprises the following successive steps: a) introducing a coagulum into at least one continuous mixer, in order to obtain a masterbatch in dried mass form, said coagulum comprising the diene elastomer and the reinforcing filler dispersed in the dried mass with a Z score greater than or equal to 80; b) conveying the mass leaving the continuous mixer into a mill in order to obtain a masterbatch in ribbon form; c) optionally, introducing the ribbon from the mill and an antioxidant into a continuous mixer such as to obtain a masterbatch comprising an antioxidant; d) after step b) or c) recovering the masterbatch having a moisture content below 1 wt.-%. The method is characterised in that the flow rates in steps a) and b) are above 500 kg/h, and in that in the case where antioxidant is present in the masterbatch obtained at the end of step d), all of the antioxidant is introduced during step c). |
