Abstract:

In this paper , RH , the complex of resorcinoland hexamethylene , was added in commercial nano-CaCO3 modified with stearic acid (CCR) to prepare modified CCR (M -CCR) via solid state method , and the composites of NRlSBRlBR blends respectively filled with M -CCR and CCR were prepared. Then , the dispersion ability , interfacial combination , processing ability and morphology of M-CCR and CCR in NRlSBRlBR blend matrix were characterized by using the rubber process analyzer (RPA) and the TEM. Moreover , the mechanical properties of the composites were investigated. The results indicate that the processing ability , the reinforcement effect , the dispersion ability and the interfacial adhesion of M-CCR in the blend matrix are all superior to those of CCR.
