Properties of Ethylene Propylene Diene Monomer/Recycled Acrylonitrile –Butadiene Rubber Blends (EPDM/rNBR): Effect of the Addition of Bamboo Fillers

摘要

Cure characteristics and physical properties of EPDM/rNBR filled bamboo fillers were studied. Results indicated that the addition of bamboo fillers has significant effects on EPDM/rNBR blends. The scorch time, t_2 decreased up to 25 phr fillers loading but increased further to 50 phr fillers loading. Cure time, t_(90) increases as the increase in bamboo fillers in the blends. At a similar blend ratio fine sizes bamboo fillers in EPDM/rNBR (S1: ≤125μm) exhibited higher value of t_2 ad t_(90) compared to EPDM/rNBR (S2: 125-250μm & S3: 250-500μm). The minimum torque, M_L also increases with increasing bamboo fillers in the blend. Meanwhile, the maximum torque, M_H of the EPDM/rNBR filled bamboo fillers were in contrast. The hardness and degree of crosslink density of the blends increased with the increase in bamboo fillers and reduce percentage of resilience at all blends. The fine sizes of bamboo fillers contributed to the better properties compared to the coarse sizes and medium sizes.
