| 中文摘要: |
| 研究稀土异戊橡胶(Nd-IR)在全钢载重子午线轮胎胎面中的应用。根据傅里叶转换红外光谱和核磁共振谱，Nd-IR的顺式1，4-结构摩尔分数大于0.98且不含有反式1，4-结构，所有的序列单元与天然橡胶(NR)一样，均以“头 尾”方式键接。Nd-IR的物理性能与NR相差不大，将其以60%的比例替代NR用于全钢载重子午线轮胎胎面胶，加工性能不受影响，轮胎的各项性能均合格，其中耐久性能远高于全NR生产的轮胎。 |
| 英文摘要: |
| The application of neodymium isoprene rubber (Nd-IR) in the tread compound of truck and bus radial tire was investigated.Fourier transform infrared (FTIR) spectroscopy and nuclear magnetic resonance (NMR) spectroscopy were carried out to characterize the structure of Nd-IR.The test results showed that the content of cis 1，4-configuration in Nd IR was above 98%，trans 1，4-configuration could not be detected， and all repeating units of Nd-IR presented "head to tail" structure，which was same as natural rubber (NR).The mechanical properties of Nd IR did not show significant difference with NR.By using Nd-IR to replace 60% of NR by weight in the tread compound of truck and bus radial tire，the processibility of the compound was not affected，the tire performance was qualified，and the endurance performance was much higher. |
