| Abstract: |
| The nano-silicon nitride was modified by low molecular polybutadiene grafted glycidyl methacrylate(LMPB-g-GMA) and atactic polypropylene grafted maleic anhydride（APP-g-MAH） respectively.The modified nano-silicon nitride/EPDM composites were prepared，and the properties were investigated.The results showed that，the modified nano-silicon nitride gave good reinforcement on EPDM.As the addition level of modified nano-silicon nitride increased，the Shore A hardness of composite changed little，and the modulus，tensile strength and tear strength generally increased at first and then decreased.The tensile properties and compression set of composite with nano-silicon nitride modified by LMPB-g-GMA were better than those by APP-g-MAH，but the thermal aging property was lower. |
