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: Abstract A variety of solutions to the problem high temperature stabilisation natural rubber (NR)/carbon–silica dual phase filler (CSDPF) composites have been compared. Enhancement in performance was observed when a small amount silica (5.5 phr) added carbon black filled (50 formulation containing conventionally stabiliser system (polymerised 1,2-dihydro-2,2,4-trimethylquinoline and N-(1,3-dimethylbutyl)-N′-phenyl-p-phenylene diamine). However, most successful approach formation novel filler-coupled which based on poly(hydromethyl siloxane) grafted with N-phenyl-1,4-phenylenediamine (PPDA). The followed via monitoring loss tensile strength as function ageing time.
