| 中文摘要: |
| 以丙烯酸酯橡胶（ACM）和乙烯丙烯酸酯橡胶（AEM）作为相容剂，研究其对混炼型聚氨酯橡胶（MPU）/丁腈橡胶（NBR）共混胶性能的影响。结果表明：在MPU/NBR共混胶中加入相容剂ACM和AEM，可以促进MPU与NBR的共硫化，使二者的硫化特性更加匹配，提高了共混胶的相容性、物理性能、耐热性能和耐热氧老化性能，相容剂AEM对共混胶的性能改善效果优于相容剂ACM；当相容剂AEM用量为20份时，共混胶的两相已完全相容。 |
| 英文摘要: |
| Acrylate rubber（ACM） and ethylene acrylate rubber（AEM） were used as compatibilizers，and their effects on the properties of mixed polyurethane rubber（MPU）/nitrile rubber（NBR） blends were studied.The results showed that adding compatibilizers ACM and AEM to MPU/NBR blends could promote the co-vulcanization of MPU and NBR，make the vulcanization characteristics between the two more compatible，and improve the compatibilities，physical properties，heat resistance and thermal oxygen aging properties of the blends.The compatibilizer AEM improved the performance of the blend better than the compatibilizer ACM.When the dosage of compatibilizer AEM was 20 phr，the two phases of the blend were completely compatible. |
