| 中文摘要: |
| 研究了共聚型氯醚橡胶丁腈橡胶共混比、促进剂NA-22用量、补强剂及软化剂对共混物性能的影响。结果表明随着氯醚橡胶用量的增加、共混物的耐低温性、耐热氧老化性、耐油性及耐CCl4和CHCL3性能提高，但拉伸强度降低；当促进剂NA-22和半补强炭黑的用量分别为1.5和60份时，氯醚橡胶/丁腈橡胶(60/40)共混物的拉伸强度及撕裂强度出现峰值；使用液体丁腈橡胶作软化剂.使共混物的耐低温性、回弹值、撕裂强度、扯断伸长率及耐油性提高，但耐热氧老化性及耐CCl4和CHCL3性能降低。 |
| 英文摘要: |
| The effects of the blending ratio of polymers and the arnounts of accelerator NA-22，reinforeing agent and softner on the properties of epiehlorohydrin-ethylene oxide copolymer(ECO)/nitrilebutadiene rubber(NBR) blend were studied.The result showed that with the inerease of the content of ECO the low temperature resistanee，the thermooxidative aging resistance and the tetraehloromethane or chloroformre sistance of the blend improved signifieantly，but the tensile strength deereased:the maximal tensile strength and tear strength of the ECO/NBR(60/40) blend were obtained when 1.5 phr of aeeeleratorNA-22 and 60 phr semi-reinforeing furnace blaek were used.When the liquid NBR was used as softner，the low temperature resistanee，resilieney.tear strength.elongation at break and oi1 resistance of the blend improved，but the thermooxidative aging resistance and the tetraehloromethane or chloroform resistance deereased. |
