| 中文摘要: |
| 采用丙烯酸酯类单体通过乳液聚合制备了丙烯酸酯橡胶(ACM)。试验研究了ACM硫化胶的性能。结果表明，ACM引入—COOH基团，用环氧树脂作硫化剂，可以实现高温快速硫化，且其硫化胶性能良好；增大带有柔性基团的单体(增塑剂)的比例，可以改善ACM硫化胶的耐低温性；增大极性大的单体(丙烯腈)的比例，可以改善ACM硫化胶的耐油性和耐热性。ACM与氟橡胶(FKM)并用初步研究结果显示，FKM的用量在50份以上时，并用硫化胶性能接近FKM。 |

| An acrylate rubber (ACM) was prepared by emulsion copolymerization.An experimental study was made on the properties of ACM vulcanizate.The results showed that the fast curing at elevated temperature was realized by introducing —COOH group into ACM and using an epoxy resin as the curing agent and thus the good physical properties of vulcanizate was obtained；the low temperature resistance of ACM vulcanizate improved by increasing the plasticizer proportion；the oil resistance and heat resistance of ACM vulcanizate improved by increasing the acry lonitrile proportion.The results of the primary study on ACM/FKM blend showed that the properties of blend vulcanizate was similar to those of FKM vulcanizate if the FKM proportion was over 50% in the blend. |
