对软丁腈N41添加不同用量的硫黄，使其产生不同的交联密度，在此基础上重点研究不同交联密度对软丁腈橡胶N41物理机械性能、压缩生热及动态性能的影响。结果表明：胶料的拉伸强度与交联密度成正比，断裂伸长率则随着硫黄用量增加而降低；胶料的压缩生热随着交联密度的增加而降低；胶料的储能模量随交联密度的增加而增加，损耗因子则随交联密度的增加而减小，并且这两个动态模量对应变、频率和温度等外界环境的依赖性较强。

In this paper, soft nitrile rubber N41 added different amounts of sulfur to produce different cross-linking density. Based on this study,we focused on the influence of the different cross-linking densi-ty on the physical and mechanical properties as well as dynamic properties of soft nitrile rubber N41 . The results showed that:the tensile strength of rubber was in direct ratio to cross-linking density,elongation at break decreased with the increase of the amount of sulfur. With the cross-linking density rising,the com-pression heat generating is reduced the storage modulus is increased and the lose factor is reduced. In addi-tion,the dynamic modulus has strong dependence on strain,frequency and temperature.
