Effect of Nano Attapulgite/Carbon Black Composite Fillers on Properties of NR/SBR/BR Blends

In this study,composite filler consisting of nano attapulgite/carbon black N770/carbon black N330 was applied in the natural rubber(NR)/styrene butadiene rubber(SBR)/butadiene rubber(BR) blends and the effect of the nano attapulgite/carbon black N770 ratio in the composite filler on the properties of the rubber blend was investigated. The result showed that,with the increase of the nano attapulgite amount,the FL and Fmax of the blends increased,curing rate was slower,and physical properties,abrasion resistance and flex properties were improved. When the ratio of nano attapulgite/carbon black N770 was 30/15,the comprehensive performance of the blends was excellent. Compared with the blends with other composite fillers in which other inorganic fillers(clay,light calcium carbonate and silica) were used with carbon black,the tensile strength and tear strength were higher than those of the blends with nano attapulgite/carbon black composite filler,flex properties was better,and abrasion resistance was slightly worse.
