Abstract | The present invention relates to a method for recycling solid waste consisting of sulphur-based vulcanised elastomers or elastomers cross-linked with peroxides. In this context, the present invention proposes recycling such waste by radical uncrosslinking in the presence of ozone and uncrosslinking agents, without applying high temperatures. The present invention also relates to the recycled elastomers and to the use of the recycled elastomers obtained by this method.
La présente invention concerne un procédé de recyclage de déchets solides d'élastomères vulcanisés à base de soufre ou réticulés avec des peroxydes. À cet effet, la présente invention propose le recyclage desdits déchets par déréticulation radicalaire en présence d'ozone et d'agents déréticulants, sans utilisation de haute températures. La présente invention concerne également les élastomères recyclés et l'utilisation de tels élastomères recyclés obtenus au moyen dudit procédé.
A presente invenção se refere a um processo para reciclagem de resíduos sólidos de elastômeros vulcanizados à base de enxofre ou reticulados com peróxidos. Nesse âmbito, a presente invenção propõe a reciclagem dos referidos resíduos por meio de desreticulação radicalar na presença de ozônio e agentes desreticulantes, sem uso de altas temperaturas. A presente invenção também se refere aos elastômeros reciclados e ao uso de tais elastômeros reciclados obtidos por meio do referido processo. |
