Abstract

In this paper, ultrafine full-vulcanized styrene-butadiene powdered rubber (UFPSBR) was introduced into natural rubber (NR)/butadiene rubber (BR) and styrene-butadiene rubber (SBR)/BR blends. The influence of UFPSBR on the mechanical and dynamic mechanical properties of both blends was thoroughly investigated for the first time. The dynamic mechanical analysis showed that for the temperature range of −10 to 0 °C, the tan δ values of both blends increased notably. This indicated a significant increase in wet traction of the materials. Unfavorable influence of UFPSBR on the abrasion resistance and heat generation was observed, which was due to the nature of the side chain group of SBR. A combination of fracture and chemical deterioration processes was observed in the presence of UFPSBR in both blends and was proposed as the abrasion mechanisms for NR/BR/UFPSBR and SBR/BR/UFPSBR vulcanizates undergoing abrasion. The experimental results depicted that adding appropriate amounts of UFPSBR will improve the mechanical and dynamic mechanical properties of elastomer blends.
