Method for producing rubbery material ready for crosslinking, comprising a continuous extrusion of crosslinked rubber, in grains and/or chips, comprising i) decrosslinking by mechanical shearing of said grains and/or chips and increasing the temperature until a decrosslinked paste is formed, ii) cooling said decrosslinked paste with the optional addition of at least one additive, and iii) mixing the cooled decrosslinked paste with at least one crosslinking agent, and collecting, at the end of this continuous extrusion, a pasty mixture forming said rubbery material ready for crosslinking.
A method for producing rubbery material ready for crosslinking, comprising
A device for producing rubbery material ready for crosslinking, comprising a continuous extrusion device comprising an upstream inlet end provided with a system for supplying crosslinked rubber, in grains and/or chips, and a downstream end for collecting said rubbery material ready for crosslinking, and, between these ends, successively a sector for decrosslinking said grains and/or chips coming from the supply system, where said crosslinked rubber is transformed into a decrosslinked paste, a cooling sector, where the decrosslinked paste is cooled and a mixing sector provided with said downstream end, wherein at least one dosing device is provided for introducing at least one crosslinking agent into the cooled decrosslinked paste.
