摘要：In this work, curing characteristics, tensile and physical properties of epoxidized natural rubber/rice husk (ENR-50/RH) compounds were investigated. Different RH loading (10, 20, 30, 40 and 50 Phr) and size (fine size at 100-300 μm and coarse size at 5-10 mm) were prepared and used. Results indicated that the scorch time (t2) and cure time (t90) became shorter with increasing RH content. In contrast, minimum torque (ML) and maximum torque (MH) increased with increasing RH content in the rubber compounds. Hardness and crosslink density showed improvement with increasing RH content. Tensile strength (Ts) and elongation at break (Eb) decreased slightly as RH content increased. However, the fine size of RH recorded better overall properties compared to the RH coarse size at same loading the rubber compound.
