| 中文摘要: |
| 用橡胶加工分析仪（RPA）和动态热机械分析仪（DMA）等研究炭黑在不同产地NR中的分散性。结果表明：4种NR相对分子质量从大到小顺序为SMR，SCR，SIR，STR，加工性能从好到坏顺序为SIR，STR，SMR，SCR；在填充50份炭黑N220的4种不同产地NR中，SMR中的炭黑分散性最好，STR和SIR次之，SCR最差；4种NR的自补强性能从高到低的顺序为：SCR，SMR，SIR，STR；炭黑N220与4种NR的相互作用从强到弱的顺序为：STR，SIR，SMR，SCR；填充50份炭黑N220的SMR硫化胶的综合性能最好，SIR和STR硫化胶次之，SCR硫化胶最差；SMR胶料兼具较好的抗湿滑性能和较低的滚动阻力。 |

| Rubber processing analyzer （RPA） and dynamic thermomechanical analyzer （DMA） were used to study the dispersion of carbon black in NR from different producing areas.The results showed that the order of the relative molecular weight of the four NR from large to small was SMR，SCR，SIR，STR，and the processability from good to bad was SIR，STR，SMR，SCR.Among the four NR from different producing areas filled with 50 carbon black N220，the dispersion of carbon black in SMR was the best，followed by STR and SIR，and SCR was the worst.The order of self-reinforcing performance of the four NR from high to low was SCR，SMR，SIR，STR，and the interaction between carbon black N220 and four NR from strong to weak was STR，SIR，SMR，SCR.The comprehensive properties of SMR vulcanizates filled with 50 phr carbon black N220 were the best，followed by SIR and STR vulcanizates，and SCR vulcanizates were the worst.SMR has both better wet-slip resistance and lower rolling resistance. |
