| 中文摘要: |
| 研究补强体系、生胶并用和硫化体系对充环烷油的溶聚丁苯橡胶（SSBR）胶料性能的影响。结果表明：对纯炭黑补强体系，炭黑用量为75份的胶料的综合性能较好，两种炭黑并用体系的胶料的综合性能提高，但耐磨性能稍差，对炭黑/白炭黑并用补强体系，白炭黑用量为20份的胶料的综合性能优异，继续增大白炭黑用量，填料分散性和胶料性能下降；SSBR并用20份顺丁橡胶，胶料的压缩生热和滚动阻力降低，耐磨性能提高，耐老化性能优异，其他性能满足使用要求；在硫化体系中硫黄用量对SSBR胶料性能的影响最大，硫黄的适宜用量为1.4～1.6份。 |

| The effects of reinforcing system，raw rubber blending and curing system on the properties of solution polymerized styrene butadiene rubber（SSBR） filled with naphthenic oil were studied.The results showed that，for the pure carbon black reinforcing system，the comprehensive properties of the compound with 75 phr carbon black were better，and the comprehensive properties of the compound with two kinds of carbon black blending system were improved，but the wear resistance was slightly poor.For the carbon black/silica blending reinforcing system，the comprehensive properties of the compound with 20 phr silica were excellent.With the increased of silica amount，the dispersion of fillers and the properties of compound decreased.When SSBR was blended with 20 phr cis-1，4-polybutadiene rubber，the compression heat build-up and rolling resistance of the compound were decreased，the wear resistance was improved，the aging resistance was excellent and the other properties met the use requirements.In the curing system，the amount of sulfur had the greatest influence on the properties of SSBR compound，and the suitable amount of sulfur was 1.4～1.6 phr. |
