| Abstract: |
| The effect of blending ratio of ethylene-acrylic elastome（AEM） and methyl vinyl silicone rubber（MVQ） on the curing characteristic，physical properties，oil resistance and dynamical mechanical properties of MVQ/AEM blend was investigated.The results showed that，as the content of AEM increased，the optimum curing time of MVQ/AEM blend prolonged，maximum torque decreased and the physical properties of vulcanizates were improved.After hot air aging，as the content of AEM increased，the retention of tensile strength and elongation at break of the MVQ/AEM blend decreased，indicating decreased aging resistance.The oil resistance was improved with the increase of AEM content，indicated by the reduced volume change and mass change of vulcanizates dipped in ASTM 1# and ASTM 3# oil.The DMA test results showed that，AEM and MVQ had good compatibility，but the low temperature performance of MVQ decreased by blending with AEM and the loss factor increased gradually with the increase of AEM content. |
