研究了4种不同粒径的PMMA磨屑粉填充的EPDM性能的变化.力学性能试验表明:EPDM以粒径为47μm的磨屑粉填充时,拉伸强度最高;以粒径为190μm的磨屑粉填充时,断裂伸长率最高.扫描电镜(SEM)形貌观察分析表明:随着磨屑粉粒径越小,磨屑粉与EPDM之间的界面结合越强.

Structure and properties of ethylene propylene diene monomer ( EPDM ) before and after filled were investigated. The results of mechanical testing showed that the tensile strength of EPDM increased as the average particle diameter became smaller, while the maximum strain before fracture of EPDM reduced. Combing the scanning electron microscopy photographs of fracture surface appearance, the specific surface area of the filler enormously increased as the average particle diameter became smaller.
