Unformatted text preview: Haake rheometer equipped with a pair of mixing rotors. The elastomer and nanofiller were mixed at 80 rpm and 177 o C for 3min, followed by the addition of the curing agent, DBPH-50, and the mixing was then continued for another 12 minutes. The change of mixing torque with time was recorded and used to assess the vulcanization behaviors of the FC2260 nanocomposites. The post curing of the nanofiller filled FC2260 was studied using DSC. A typical rubber vulcanization process involves multiple and complex reactions. Models have been developed to depict the reaction process and give insight to the vulcanization mechanisms. Two types of kinetic models based on DSC measurement, applicable to isothermal and M= ρ * Vn * 0.7...
