Effect of Temperature on Rheological Properties of SBR Compounds Reinforced by some Industrial Scraps as a Filler

Sameer Hassan Al-Nesrawy, Mohammed Al-Maamori and Hamad Rahman Jappor

The effect of fillers such as mix of carbon black and cement waste on rheological characteristics are studied in styrene butadiene rubber (SBR). The present study carried out through four recipes according to the loading level of mixed of industrial scraps (cement waste) and carbon black (N375) (C.B) that it used as reinforcement materials in the compounds. On the other hand, the rheological properties tests carried out by Rheometer according ASTM D 2705 specification in order to using these compounds in fender ship application. All compounds are composed of carbon black N375 (10, 20, 30, 35) pphr and cement waste (10, 20, 30, 35) pphr. The viscosity, minimum torque, maximum torque, scorch time, optimum cure time Tc90, optimum cure and thermoplasticity were examined at different temperature (165, 175, 185)oC. The results appeared that the rheographs were varied according to loading level, therefore; viscosity, minimum torque, maximum torque, optimum cure and thermoplasticity were decreased with increasing temperature and increased with increasing the loading level of mix C.B and cement waste. Also, the scorch time optimum cure time Tc90 was decreased with increasing temperature, loading ratio of C.B and cement waste.
