Abstract: NR/SBR blend is an important raw material to produce the tire tread. Excellent tensile strength, high skid resistance and high abrasion resistance are the advantages of NR/SBR blend. In order to develop the mechanical property of rubber product, the reinforcing filler carbon black and silica is widely used. In this work, the influence of carbon black and silica on the properties of NR/SBR blends was investigated. The rubber blend ratio of NR and SBR was achieved as 50/50 percent by volume. The initial Mooney viscosity of NR and SBR was carefully controlled to be nearly equal, while the carbon black and silica loadings were varied from 0 to 50 phr. The study of NR/SBR composite on both dynamic and static properties was carried out. RPA2000, DMTA and Goodrich Flexometer were employed to investigate the dynamic mechanical property of blend. Moreover, the phase morphology, tension and electrical property were also reported. The NR/SBR blend is classified as the partial miscible blend and simultaneously generates the sulfur crosslink in NR and SBR phase. Furthermore, the filler-filler interaction of both carbon black and silica in NR and SBR phase of rubber blend shows a different characteristic. Both carbon black and silica establish the filler network within SBR phase easier than NR phase. However, carbon black particles could conveniently produce the continuous structure within NR phase. The enhancement of storage modulus, heat buildup tensile strength and crosslink density can be observed when increasing carbon black and silica loading.
