Abstract:

Modified crumpled graphene balls (MCGB) with hydrophobicity were prepared through a reflux reaction with stearic and oleic acids. The structure and morphology were characterized by Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). The dispersion properties and friction properties of different mass content of MCGB in base oil were studied, and the anti-friction mechanism of MCGB in lubricating oil was discussed. The results showed that the base oil with adding a small amount of MCGB can obviously improve the anti-wear and anti-friction capacity, and the optimal content of MCGB was 0.010%. But the anti-friction performance would be ineffective when adding excessive MCGB.

摘要:

利用带有长链烷烃的硬脂酸和油酸对球状石墨烯进行表面修饰,得到亲油性褶皱石墨烯球(MCGB),采用FTIR、SEM等方法对其结构和形貌进行表征;研究了MCGB不同比例添加量在基础油中的分散性能和摩擦性能,并探讨MCGB在润滑油中的润滑机理。结果表明:基础油中添加少量MCGB可以明显改善其抗磨减摩效果,其中添加量为0.010%时效果最佳,但添加过量其减摩性能会失效。
