中文摘要：

采用卤化（氟化、溴化、碘化）及混合氧化方法对丁腈橡胶（NBR）表面进行化学改性,研究改性方法对NBR耐油性能和耐磨性能的影响。结果表明：氟化、溴化、碘化和混合氧化改性均能提高NBR试样的邵尔A型硬度、拉伸强度和拉断伸长率等物理性能,其中氟化和混合氧化改性效果尤为显著;混合氧化改性试样的耐油性能明显提高;所有改性试样的耐磨性能均提高,其中混合氧化改性效果最好。

英文摘要：

The halogenation （fluoride, bromide and iodide） and mixed oxidation method were used for chemical modification of NBR surface, and the effect of surface modification on the oil resistance and wear resistance of NBR was studied. The results showed that, fluoride, bromide,iodide and mixed oxidation could improve the physical properties of NBR, such as Share A hardness, tensile strength and elongation at break, wherein the effect of fluorination and mixed oxidation was quite effective. The oil resistance of NBR was significantly improved by using mixed oxidation. The wear resistance of all the modified NBR was improved, wherein the effect of mixed oxidation was the best.
