| 摘 要： | 探讨了白炭黑Z125用量对NR和S-SBR硫化胶性能的影响.结果表明:随Z125用量增大,NR和S-SBR两种硫化胶的物理机械性能得到明显改善,且分别在填充量为45 phr和60 phf时有较好的综合物理机械性能;与S-SBR硫化胶相反,NR硫化胶的耐疲劳破坏性随Z125用量增大明显降低;随屈挠次数的增加,NR硫化胶的割口尺寸单调增大,而S-SBR硫化肢的初始割口尺寸迅速增大,之后稍有升高;随Z125用量增大,NR和S-SBR硫化肢的损耗因子峰值(tan δmax)减小,0～70℃时,NR的损耗因子值(tan δ)和弹性模量(E')增大,S-SBR高于20℃时的tanδ艿值增加,E,基本呈增大趋势.

| Abstract: | The effects of dosage of silica Z125 on dynamic mechanical properties and bending destroyed durability of NR and S-SBR vulcanizates were studied.The results illuminated that mechanical properties of NR and S-SBR vulcanizates were improved with increasing of the Z125 dosage,and when the Z125 dosage was 45phr and 60phr,NR and S-SBR vulcanizates had better mechanical properties. The results also indicated:when the bending time increased,the bending destroyed durability of NR vulcanizates became worse,on the co... |
