摘　　要：研究丙烯腈含量、饱和度和硫化体系对氢化丁腈橡胶(HNBR)硫化胶耐盐酸性能的影响。结果表明:不同牌号HNBR硫化胶经过耐盐酸试验后,均呈硬度和体积增大、拉伸强度和拉断伸长率减小的趋势;丙烯腈含量较小、饱和度较低的HNBR硫化胶的耐盐酸性能更好;与采用过氧化物硫化体系的HNBR硫化胶相比,采用硫黄硫化体系的HNBR硫化胶的耐盐酸性能更好。The effects of acrylonitrile content,saturation degree and vulcanization system on the hydrochloric acid resistance of hydrogenated nitrile-butadiene rubber(HNBR)were studied.The results showed that different grades of HNBR vulcanizates showed a trend of increasing hardness and volume and decreasing tensile strength and elongation at break after undergoing the hydrochloric acid resistance test.Vulcanizates of HNBR with a smaller acrylonitrile content and lower saturation degree had better hydrochloric acid resistance.Compared with HNBR vulcanizates using the peroxide vulcanization system,HNBR vulcanizates using the vulcanization system had better hydrochloric acid resistance.
