技术领域
本发明涉及润滑油加工技术领域,具体涉及了纳米碳分子高性能润滑油。
背景技术
润滑油是用在各种类型汽车、机械设备上以减少摩擦,保护机械及加工件的液体或半固体润滑剂,主要起润滑、辅助冷却、防锈、清洁、密封和缓冲等作用。润滑油一般由基础油和添加剂两部分组成。基础油是润滑油的主要成分,决定着润滑油的基本性质,添加剂则可弥补和改善基础油性能方面的不足,赋予某些新的性能,是润滑油的重要组成部分。
近年来,由于纳米固体润滑材料具有独特的物理、化学及机械等优异性,故业者遂将其开发成为各种纳米固态润滑添加剂。纳米固体润滑材料主要是非活性的纳米级固体颗粒,具有高的热稳定性、机械稳定性以及化学稳定性,在高温、重负荷、高速等使用条件下不易发生氧化、分解与失效,具有优良的抗磨减摩性能和较高的高温使用寿命,而且纳米颗粒因粒度小而易于进入摩擦表面,形成易剪切的表面膜,有效避免摩擦副表面的直接接触,从而保护相对运动表面不受损伤,降低摩擦与磨损。不仅如此,石墨、二硫化钼和二硫化钨等纳米材料还具有环境友好的特性,将其作为油品添加剂不仅具有较好的抗磨和减摩性能,有效解决有机化合物添加剂的环保和易耗损和润滑油高温使用寿命短等问题,表现出了广阔的应用前景。
