EPDM과 SBR고무 블렌드 혼합물의 노화특성 및 물리적 특성에 관한 연구

Abstract

This study measured the aging and physical properties of EPDM blends by mechanical mixing type. The measurements were conducted using a moving die rheometer (MDR), universal testing machine (UTM), compression set and dynamic mechanical (DMA). The properties of aging properties increased with increasing SBR contents. Specially at the SBR-rich area tensile strength and Elongation at break increased. As the SBR loading increased Hardness, scorch time and optimum cure time decreased. Dynamic characteristics determined from a Eplexor(GABO) generally showed two glass transition() for the entire blends, peak monotonically shifted toward the higher temperature with the increasing SBR contents.
