| 中文摘要: |
| 以促进剂CZ为配体合成N-环己基-2-苯并噻唑次磺酰胺钕配合物，并对其在NR/SBR并用胶中的应用性能进行研究。通过元素分析和红外光谱分析确定稀土配合物的组成为Nd(CZ)Cl3·Nd(OH)Cl2·H2O。稀土配合物具有次磺酰胺类促进剂的延迟性能，适用于橡胶厚制品的硫化；热空气老化后硫化胶的硬度、300%定伸应力和撕裂强度增大，拉伸强度、拉断伸长率和拉断永久变形减小；可降低胎面胶的滚动阻力和生热。 |
| 英文摘要: |
| The N-cyclohexyl-2-benzothiazole sulfenamide neodymium complex was synthesized with accelerator CZ as ligand，and its application in NR/SBR blend was investigated.It was confirmed by element analysis and infra-red spectroscopy analysis that，the composition of the rare earth complex was Nd(CZ)Cl3·Nd(OH)Cl2·H2O. The rare earth complex had a delay characteristic of sulfonamide accelerators and was suitable for vulcanization of thick-walled rubber goods；after heat aging，the Shore A hardness，the modulus at 300% elongation and tear strength of vulcanizate were increased，the tensile strength，elongation at break and tensile set at break of vulcanizate were decreased；the rolling resistance and the heat build-up of tread compound with the rare earth complex could be decreased. |
