Nitrilebutadiene rubber (NBR) materials filled by conventional ZnO (cZnO) and nanoZnO (nZnO) were prepared,and the material properties and physical and mechanical performances of Nitrilebutadiene rubber (NBR) containing different kinds of Zinc Oxide (ZnO) were analyzed.The influences on tribological properties of NBR by types of ZnO were studied by using MPV600 abrasive wear tester,the morphology of worn surface was measured by scanning electron microscopy (SEM),and the wear mechanism was analyzed.The results indicate that,compared with NBR containing cZnO,the nZnO can further improve the tensile strength and tensile stress of NBR.The maximum torque of NBR containing nZnO is higher than that of NBR containing cZnO,and the scorch time and optimum cure time of NBR containing nZnO are both shortened.The NBR containing nZnO exhibits the more outstanding wear resistance,which is mainly due to its greater crosslinking density and higher systematic hardness.The wear mechanism of NBR containing nZnO is abrasive wear and little adhesive wear,while that of NBR containing cZnO is abrasive wear and serious adhesive wear.
