The role of silica and carbon-silica dual phase filler in a novel approach to the high temperature stabilisation of natural rubber based composites

摘要

A variety of solutions of the problem of high temperature stabilisation of natural rubber(NR)/carbon-silica dual phase filler (CSDPF)composites have been compared. Enhancement in stabilisation performance was observed when a small amount of silica (5.5 phr)was added to a carbon black filled(50 phr)formulation containing a conventionally added stabiliser system(polymerised 1,2-dihydro-2,2,4-trimethylquinoline and N-(1,3-dimethylbutuyl)-N'-phenylene diamine).
