| 中文摘要: |
| 采用高温共混技术制备白炭黑/炭黑/溶聚丁苯橡胶(SSBR)和白炭黑/炭黑/乳聚丁苯橡胶（ESBR）复合材料，并分别对其结构和性能进行研究。结果表明，在填充剂总量不变的前提下，随着白炭黑用量的增大，白炭黑/炭黑/SSBR和白炭黑/炭黑/ESBR复合材料物理性能呈现加和效应的特点，动态性能提高，表面电阻和体积电阻率增大；白炭黑/炭黑/SSBR复合材料物理性能与白炭黑/炭黑/ESBR复合材料差别较小，但前者动态性能较好；添加导电炭黑使复合材料抗静电性提高、物理性能下降；当白炭黑/炭黑并用比为35/35、导电炭黑用量不大于5份时，白炭黑/炭黑/SSBR复合材料的综合性能较好。 |

| The silica/carbon black/solution-polymerized styrene-butadiene rubber(SSBR) and sili-ca/carbon black/emulsion-polymerized styrene-butadiene rubber(ESBR) composites were prepared by high temperature blending method，and the structures and properties of the composites were in-vestigated.The results showed that the physical properties of silica/carbon black/SSBR and silica/carbon black/ESBR composites presented the characteristics of additive effects，dynamic properties were improved，and the surface resistivity and volume resistivity were increased as the addition level of silica increased while the total filler amount was kept constant；the difference of physical properties between silica/carbon black/SSBR and silica/carbon black/ESBR composites was small，but the dynamic properties of the former was better；the anti-static properties of the two composites were improved，but the physical properties were decreased by adding conductive carbon black；when the blending ratio of silica/carbon black was 35/35 and the addition level of conductive carbon black was less than 5 phr，the silica/carbon black/SSBR composite possessed better comprehensive properties. |
