METHODS OF FUNCTIONALIZING RECLAIMED ELASTOMER MATERIAL AND COMPOSITIONS COMPRISING THE SAME

摘要

A method of functionalizing reclaimed elastomer material is described. The method involves subjecting particles of the reclaimed elastomer material to shear at temperatures less than 100° C. such that inter-chain bonds of the reclaimed elastomer material are cleaved wherein the particles of the reclaimed elastomer material have a size of 60 mesh or smaller. The reclaimed elastomer material can be subjected to shear in the presence of a modifier which selectively promotes the cleavage of inter-chain bonds in the reclaimed elastomer material. A functionalized reclaimed elastomer material made by a method as described above and an elastomer compound which comprises the functionalized reclaimed elastomer material are also described.

主权项

1. An elastomer compound comprising:
uncured elastomer; functionalized reclaimed elastomer material, wherein the reclaimed elastomer material is functionalized by subjecting particles of the reclaimed elastomer material comprising a size less than or equal to 40 mesh to shear at temperatures less than 100° C. such that inter-chain bonds of the reclaimed elastomer material are cleaved; a filler; and a crosslinking agent.
