Abstract

L’invention concerne un procédé de traitement d’un caoutchouc naturel qui comprend l’alimentation dans une machine à vis sans fin d’un caoutchouc naturel sous la forme d’un coagulum humide, la machine à vis sans fin étant une extrudeuse qui comprend un fourreau et qui est équipée d’un dispositif d’injection qui comprend un ou plusieurs orifices débouchant dans le fourreau, dits points d’injection, et d’une filière à trous en bout de vis, puis l’injection d’un peptisant dans le caoutchouc naturel par l’intermédiaire du dispositif d’injection, ensuite la compression du caoutchouc naturel dans le fourreau à une température allant de 130°C à 210°C, suivie d’une détente éclair adiabatique à une pression différentielle supérieure ou égale à 40 bars. Le procédé conduit à l’obtention de caoutchoucs naturels qui présentent un compromis amélioré entre leur résistance au vieillissement par thermooxydation et leur aptitude à être travaillés dans des outils de mélangeage ou de calandrage.
