METHOD FOR RECYCLING ELASTOMERS, RECYCLED ELASTOMERS, AND USE OF THE RECYCLED ELASTOMERS

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...

Beschreibung
Zusammenfassung:	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 presente invención se refiere a un proceso para el reciclaje de residuos sólidos a partir de elastómeros vulcanizados a base de azufre o reticulados con peróxidos. En este contexto, la presente invención propone el reciclado de dichos residuos mediante desreticulación radicalaria en presencia de ozono y agentes desreticulantes, sin el uso de altas temperaturas. La presente invención también se refiere a elastómeros reciclados y al uso de dichos elastómeros reciclados obtenidos mediante dicho proceso.
