It was concluded that while nano - Al2O3/carbon black mass ratio was 1/1, tensile strength and tear strength were best, nano - Al2O3/ carbon black mass ratio was 3/1, abrasive resistance and fatigue resistance were the best.

• 结果表明,当Al2O3/炭黑质量比为1/1时,天然橡胶硫化胶的拉伸强度和撕裂强度最高,当Al2O3/炭黑质量比为3/1时,天然橡胶硫化胶的耐磨性和耐疲劳性能最佳。
