| 中文摘要: |
| 研究星形溶聚丁苯橡胶（S-SSBR）与异戊橡胶（IR）不同并用比下生胶及其炭黑混炼胶的非牛顿特性和流变特性。结果表明：S-SSBR生胶及其炭黑混炼胶在高剪切作用下容易发生大分子链断裂，从而使其牛顿性增强，非牛顿指数增大；S-SSBR/IR并用胶表现出剪切变稀的非牛顿行为；IR的加入能够改善S-SSBR的松弛，提高其流变性能。 |
| 英文摘要: |
| The rheological properties of raw rubber and carbon black filled compound of S-SSBR/IR blends were investigated.The results showed that the macromolecular chain scission of the raw rubber and carbon black filled compound of S-SSBR could be found under high shear stress，which provided the S-SSBR increased Newtonain behavior and higher rheological index.The non-Newtonian behavior of shearing thinning could be found in the S-SSBR/IR blends.Blending with IR could improve the relaxation and rheological properties of S-SSBR. |
