| 中文摘要: |
| 研究白炭黑和偶联剂Si69用量对溶聚丁苯橡胶（SSBR）胶料白炭黑分散性以及物理性能的影响。结果表明：随着白炭黑用量的增大，SSBR硫化胶的白炭黑分散性下降，硬度增大，拉伸强度和撕裂强度在白炭黑用量为60份时最大；在填充65份白炭黑的SSBR胶料中，当偶联剂Si69用量为6份时，SSBR硫化胶的白炭黑分散性和物理性能最好。 |
| 英文摘要: |
| The effects of the addition level of silica and coupling agent Si69 on the silica dispersion and physical properties of solution polymerized styrene butadiene rubber（SSBR） compound were studied. The results showed that，as the addition level of silica increased，the silica dispersion in the SSBR vulcanizate decreased，the hardness increased，and the tensile strength and tear strength of the vulcanizate filled with 60 phr silica were the maximum. In the SSBR compound filled with 65 phr silica，when the addition level of coupling agent Si69 was 6 phr，the silica dispersion and physical properties of SSBR vulcanizate were the best. |
