| 中文摘要: |
| 对钕系顺丁橡胶((BR9100)的基本性能和实用性能进行了研究。结果表明，BR9100与传统的镍系顺丁橡胶(BR9000)相比，具有分子链规整性好、相对分子质量高、相对分子质量分布指数宽、分子中顺式-1 ,4结构摩尔分数高等特点。BR9100硫化胶的力学性能、生热、耐热稳定性优于传统的BR9000;在胎面胶加工性能方面，胎冠胶混炼胶填充因数由0.738提高到0.753，胎侧胶混炼胶填充因数由0.749提高到0.767,BR9100可获得与BR9000相同的加工性能;在胎体胶加工性能方面，在相同的工艺条件下BR9100达到与BR9000相当的水平。与传统BR9000生产的轮胎相比，采用BR9100胶料试制的9.00-20 16PR轮胎耐久性能提高32.9%，高速性能提高54.2%。 |

| The basic and functional properties of Nd-BR(BR9100) were investigated.The results showed that BR9100 featured better regularity of molecular chain，higher molecular weight，broader molecular weight distribution and higher cis-1,4 structure content in molecule when compared to Ni-BR(BR9000),BR9100 was superior to BR9000 in terms of mechanical properties，heat build-up and thermal stability of vulcanizate;the processibility of BR9100 compound was the same as that of BR9000 compound when the filling factor of mix increased from 0.738 to 0.753 for crown compound,from 0.749 to 0.767 for sidewall compound;and theprocessibility of BR9100 cordply compound was comparable to that of BR9000 cord ply compound under the same processing conditions.The endurance of 9.00-20 16PR tire made of BR9100 compound increased by 32.9% when compared to that of BR9000 compound and the high speed performance increased by 54.2%. |
