This paper studied the influence on the properties of SBR/BR composites filled with carbon black (CB) and silica via adding epoxidized natural rubber (ENR‐25) as a compatilizer. Payne effect, morphology, crosslink density, mechanical, and dynamic properties were studied. The results showed Payne effect receded by adding ENR‐25 to SBR/BR/CB/silica composites and the aggregation of CB and silica both weakened as well. Thus, tear strength and modulus were improved significantly, also the crosslink density and bond rubber content Dynamic Mechanical Analyzer (DMA) data indicated the tanδ value at 0°C and 60°C increased when CB was replaced by silica. Meanwhile, the value at 0°C exhibited a greater improvement than that at 60°C when adding ENR‐25, which means an excellent wet traction performance. The abrasion loss and aging resistance presented well with ENR‐25 as a compatilizer, but no improvement on the heat build‐up performance. POLYM.
