摘　　要：本文研究了低锌含量的新型硫化活性剂SR709用量对NBR硫磺硫化时胶料各项性能的影响，并与ZnO进行了对比。结果表明，SR709对NBR硫磺硫化具有明显的活性作用，在1份至5份用量范围内，添加3份SR709胶料的综合性能最佳，硫化胶的力学性能、回弹性、耐热空气老化性能和压缩永久变形达到添加5份ZnO硫化胶相应的水平，而3份SR709的锌含量仅为5份ZnO的28％，因此SR709可替代ZnO在NBR中使用，达到减锌环保的目的。Effects of low zinc content studied, compared with ZnO. The result curing active agent SR709 on sulfur-cured NBR were indicated that SR709 showed obvious curing active effect. The mechanical properties, the elastic resilience, the hot air aging resistance and compression permanent set of the vulcanizate containing 3 phr the vulcanizate contained 5 phr ZnO. The application of SR709 will be help to reduce the zinc content. SR709 were closed to those of in NBR product instead of ZnO
