摘　　要：研究了NBR/HNBR共混比对其共混胶硫化特性、力学性能、耐热空气老化性能及耐臭氧性能的影响。结果表明,随着HNBR用量的增大,共混胶硫化时间先缩短后延长,力学性能先降低后升高,耐热空气老化性能提高,耐臭氧老化性能也提高。Effects of NBR/HNBR blending ratioes on the curing characteristic, mechanical proper- ties, heat aging stability and ozone resistance of the blends were studied in this paper. The results showed that the curing time and mechanical properties of NBR/HNBR blends decreased at first and then increased with the increase of the content of HNBR, and the ozone aging resistance and heat air aging resistance were improved.
