| 对不同并用比的天然橡胶（NR）/顺丁橡胶（BR）并用胶进行阿克隆磨耗试验，并表征和计算NR/BR并用胶的磨屑分形维数，探究NR/BR并用胶的耐磨性能与磨屑分形维数的关联性。结果表明：随着NR/BR并用比的增大，NR/BR并用胶的阿克隆磨耗量先减小后增大，NR/BR并用比为60/40时并用胶的阿克隆磨耗量最小；NR/BR并用胶的磨屑分形维数先增大后减小，NR/BR并用比为60/40时磨屑分形维数最大，NR/BR并用胶的磨屑分形维数与阿克隆磨耗量的变化趋势相反；NR/BR并用胶的磨屑团聚程度越大，磨屑基团分形维数越大。 |
| 英文摘要: |
| The Akron abrasion test was carried out on natural rubber（NR）/cis-1，4-polybutadiene rubber（BR） blends with different blending ratios，and the wear debris fractal dimensions of NR/BR blends were characterized and calculated to explore the relationship between wear resistance and wear debris fractal dimensions of NR/BR blends.The results showed that，with the increase of NR/BR blend ratios，the Akron wear amounts of NR/BR blends decreased first and then increased，and the Akron wear amounts of NR/BR blend was the smallest when NR/BR blend ratio was 60/40.The wear debris fractal dimensions of NR/BR blend increased first and then decreased，and the wear debris fractal dimension of NR/BR blend was the largest when NR/BR blend ratio was 60/40，the changing trend of the wear debris fractal dimensions of NR/BR blends was contrary to that of the Akron wears.The higher the degree of agglomeration of the wear debris of NR/BR blend was，the greater the wear debris group fractal dimension was. |
