摘　　要：系统对比了国内外四种牌号氯丁橡胶混炼胶的加工特性及硫化胶的综合性能。结果表明,在三种国产牌号的氯丁橡胶中,SN232牌号的氯丁橡胶的加工性能最优且综合物理机械性能最好,压缩疲劳温升较小。相比而言,国产的SN232牌号的氯丁橡胶的综合性能与日本进口S40V牌号的氯丁橡胶最为接近,可作为替代进口S40V的国产橡胶牌号。The processing characteristics of the compounds and comprehensive performance of vulcanized rubber for four different grades of chloroprene rubber blends both at home and abroad have been compared systematically.The results show that among the three domestic grades of chloroprene rubber,SN232 grade chloroprene rubber has the best processing performance and comprehensive physical and mechanical properties,with a smaller heat bulid-up.By comparison,the comprehensive performance of domestically produced SN232 grade chloroprene rubber is closest to that of Japanese imported S40V grade chloroprene rubber,and it can be used as a substitute for imported S40V grade of domestically produced rubber.
