Abstract:
In this work, a series of C 3 N 4 /SiO 2 nanohybrids were prepared and incorporated to solution polymerized styrene‐butadiene rubber/butadiene rubber (SSBR/BR) to prepare “green tire” tread rubber. As expected, C 3 N 4 /SiO 2 nanohybrids are uniformly dispersed in SSBR/BR, and SiO 2 possesses a small average particle size of ~15 nm. In addition, the interfacial interaction between C 3 N 4 /SiO 2 nanohybrids and rubber matrix are significantly enhanced. Hence, the mechanical properties of C 3 N 4 /SiO 2 ‐SSBR/BR nanocomposites are greatly improved. The tensile strength of 5% C 3 N 4 /SiO 2 ‐SSBR/BR nanocomposites (5 wt% C 3 N 4 in C 3 N 4 /SiO 2 ) improved 1580% compared to pristine SSBR/BR. Furthermore, dynamic mechanical analyses indicate the increasing wet skid resistance (10.8% higher) and decreasing rolling resistance (50.5% lower) of 5% C 3 N 4 /SiO 2 ‐SSBR/BR nanocomposites compared with SiO 2 ‐SSBR/BR. In addition, the wear volume and heat built‐up are reduced at the same time. This work paves the way to prepare high comprehensive performance “green tire” and could be extend to the reinforcement of elastomer composites.
