| 中文摘要: |
| 研究不同粒径炭黑对丁苯橡胶（SBR）硫化胶拉伸应力-应变行为的影响。结果表明：炭黑用量相同时，炭黑N330填充的SBR硫化胶的拉伸强度、应变能保持率、撕裂强度和撕裂模量最大，其在断裂时的负荷、位移以及裂纹尖端开口位移（CTOD）也最大；随着炭黑用量的增大，3种炭黑填充的SBR硫化胶都出现了逾渗现象，应力弛豫曲线的斜率绝对值增大，应力软化效应增强。 |

| The effect of carbon black with different particle sizes on tensile stress-strain behavior of styrene butadiene rubber （SBR） vulcanizates was studies.The results showed that，when carbon black amount was the same，the tensile strength，strain energy retention rate，tear strength and tear modulus of SBR vulcanizate filled with N330 carbon black were the maximum，the load，displacement and crack tip opening displacement （CTOD） during fracture were also the maximum.As carbon black amount increased，SBR vulcanizates filled with three types of carbon black exhibited percolation phenomenon，the absolute value of the slope of the stress relaxation curve increased，and the stress softening effect was enhanced. |
