摘要

分别使用高分子量和低分子量杜仲胶（EUG）制备了杜仲胶/三元乙丙橡胶（EPDM）混合物，并对其物理性质和成分相容性进行了研究。当高分子量 EUG 的含量为 10 wt%时，共混物的物理性能和成分相容性均较好。当其含量进一步增加时，物理性能逐渐变差，扫描电镜、电致发光扫描（DSC）和 DMA 图的结果表明成分相容性较差。用低分子量的 EUG 制备的共混物在一定的混合比例范围内可以获得更好的相容性。当 EUG 含量为 20 wt% 时，共混物的拉伸强度达到最大值，比纯 EPDM 高 49.9%，回弹性提高了 5%，耐磨性几乎保持不变。

Constituent compatibility and physical properties of bio-based EUG/EPDM blends

Eucommia ulmoides gum (EUG)/ethylene propylene diene monomer (EPDM) blends were prepared using EUG with high and low molecular weight, respectively, and their physical properties and constituents compatibility were investigated. The blend exhibited superior physical properties and constituents compatibility when EUG with high molecular weight occupied 10 wt%. When its content increased further, the physical properties deteriorated gradually，the results of SEM, DSC, and DMA diagrams indicated poorer constituents compatibility. The blends prepared from EUG with low molecular weight can achieve better compatibility in a comprehensive range of blending ratio. When the EUG content was 20 wt%, the maximum tensile strength of the blend was observed, which was 49.9% higher than that of pure EPDM, its rebound resilience ascended by 5%, and the wear resistance remained nearly unchanged.
