【Abstract】 Rare earth oxides modified composites were prepared using HNBR as the substrate, and the effects of rare earth oxide types and dosages on the mechanical properties and hot air aging properties of the composites were studied.The results showed that the addition of a certain amount of lanthanum oxide or cerium oxide could significantly improve the mechanical properties and hot air aging properties of the composites.The addition of 2 phr of cerium oxide could greatly improve the tensile strength, tear strength and hot air aging properties of the composites.更多还原
