    摘要:

    新型碳纳米材料石墨烯(Gr)作为添加剂在矿物油中已有广泛的应用研究,但是在植物油中应用研究相对较少。以植物油蓖麻油作为润滑基础油,油酸修饰的石墨烯(mGr)作为添加剂,配制不同质量分数mGr的混合蓖麻油,在四球摩擦试验机上开展混合蓖麻油的润滑性能研究,讨论mGr和蓖麻油相互作用的机制。试验结果发现,功能团修饰后的mGr能够改善蓖麻油润滑性能,含质量分数0002%mGr的混合蓖麻油润滑下的磨斑直径和平均摩擦因数最低,比纯蓖麻油润滑分别减小148%和237%,其对应的钢球表面磨损程度最轻;mGr在试验初始阶段与蓖麻油的协同润滑作用不明显,而在中后阶段能改善蓖麻油的润滑性能。

    Abstract:

    New nanomaterials of graphene as themineral oil’s lubricant additives have been studied extensively,but very few researches are related to the vegetable oil.With the castor oil as the base oil,the graphene modified with oleic acid as the additive,the mixed castor oils with different weight content of modified grapheme were prepared,and the lubrication properties were investigated by using fourball friction testing rig.The results show that the modified graphene can improve the lubrication performance of castor oil,when the weight content of modified grapheme reaches 0002% in the mixed castor oil,the wear scar diameter and the average friction coefficient are decreased by about 148% and 237%,respectively,and the degree of the worn surface of the steel balls is the lowest.Furthermore,the results indicate the synergy between modified graphene and castor oil is not significant at initial stage of the test,but improving the lubricating performance of castor oil at the late stage.
