| 中文摘要: |
| 研究了不同并用比的氯醚橡胶(ECO)与 NBR-26，NBR-33和NBR-41并用胶的力学性能、耐老化性能和耐油性能。结果表明，NBR-26，NBR-33和NBR-41的用量在10～40份的范围内，对胶料的拉伸强度和扯断伸长率的影响不大；随着 NBR-26的用量增大，硫化胶在油中的体积变化率增大，而且在 100 ℃油中的体积变化率尤为明显；随着NBR-33的用量增大，硫化胶在100 ℃油中的体积变化率呈上升的趋势；随着NBR-41的用量增大，硫化胶在100 ℃油中的体积变化率明显下降。 |
| 英文摘要: |
| The mechanical properties，heat aging properties and oil resistance of ECO/NBR-26，ECO/NBR-33 and ECO/NBR-41 with different blending ratios were investigated.The results showed that the tensile strength and elongation at break of the blend changed little when 10～40 phr of NBR-26，NBR-33 or NBR-41 were used；the volume swell of the blend vulcanizate in oil，particularly in oil at 100 ℃ increased as the proportion of NBR-26 or NBR-33 in the blend increased；and the volume swell of the blend vulcanizate in oil at 100 ℃ decreased significantly as the proportion of NBR-41 in the blend increased. |
