| 中文摘要: |
| 研究芳纶短纤维长度对天然橡胶（NR）/溶聚丁苯橡胶（SSBR）并用胶性能的影响。结果表明：随着芳纶短纤维长度的增大，NR/SSBR并用胶的交联密度和储能模量增大，填料网络化程度增大，填料分散性变差；加入长度为1 mm的芳纶短纤维时，NR/SSBR并用胶的拉伸强度较大，耐磨性能较差；加入长度为3 mm的芳纶短纤维时，NR/SSBR并用胶的邵尔A型硬度、100%定伸应力和撕裂强度较大，DIN磨耗量较小。 |
| 英文摘要: |
| The effect of aramid short fiber lengths on the properties of natural rubber（NR）/solution polymerized styrene butadiene rubber（SSBR） blends was studied.The results showed that with the increase of aramid short fiber length，the crosslinking density and storage modulus of NR/SSBR blend increased，the filler network degree was enlarged，and the filler dispersion was worsed.When aramid short fiber with 1 mm of length was added，the tensile strength was larger，wear resistance was poor.When aramid short fiber with 3 mm of length was added，the Shore A hardness，tensile stress at 100% elongation and tear strength of NR/SSBR blend were larger，and the DIN abrasion was smaller. |
