英文摘要： The study on thermal conductivity of styrene-butadiene rubber (SBR) and its blends is critical and desirable for the development of high performance tires and to strengthen the international core competency of domestic tires. The modification of SBR by novel carbon fillers such as graphene and carbon nanotubes should be of great potential in improving the thermal conductivity and mechanical properties of rubbers for tire tread. This project aims to explore the relationships among composition, structure, thermal conductivity and dynamic mechanical properties of novel carbon filler modified SBR and its blends for developing highly thermally conductive rubbers for tires. The controllable preparation and modification of novel carbon fillers, the preparation methods of SBR and its blends, the effects of novel carbon fillers on the structure and properties of SBR vulcanizates, the influencing factors and controlling methods of thermal conductivity of SBR vulcanizates, and the establishment of thermal conductivity models by finite element method (FEM) will be studied. The application properties of novel carbon filler modified SBR and its blends for high performance tire tread will be studied. The innovation points of this project are especially embodied in the studies on the relationships among the structure, thermal c
