Verfahren und Anlage zur Replastifizierung von Altgummimehlen

摘要

The invention relates to a method for replastifying used rubber powder wherein a powder mixture of chemical activators is produced and subjected to a mechanochemical treatment. Said method improves bonding and co-vulcanization of the mixture in an original fresh mixture as well as the surface quality of freely vulcanized articles by briefly heating the mixture before conducting mechanochemical treatment, wherein an ester plasticizer is also added.
