三元乙丙橡胶共混改性的研究进展

Research progress in modification and blending of ethylene-propylene-diene monomer

综述了三元乙丙橡胶(EPDM)与其他橡胶共混及无机纳米粒子改性EPDM的研究进展,通过共混使EPDM共混胶兼具不同橡胶的特性,如优良的物理机械性能、黏合性、耐热老化性能、耐化学药品、介电性能及加工性能等;通过改性,可使EPDM纳米复合材料不仅具有优异的综合性能,还具有相对密度小、高充油、高填充性以及与多种高聚物良好的相容性。

The research progress of ethylene-pro- pylene-diene monomer（EPDM） were reviewed with 26 references in blending with other rubbers and modification with inorganic nanoparticles. Blending with other rubbers, EPDM was given different char- acters, such as excellant mechanical properties, bonding properties, heat aging resistance, resistance to chemical reagents, dielectric properties and pro- cessing properties. Modified by inorganic nanoparti-cles, EPDM not only had good overall performance, but also possessed lower relative density, higher oil extending and filler filling properties, better compat- ibility with other polymers.
