Description
技术领域
本发明涉及一种润滑油添加剂,特别涉及一种石墨烯纳米润滑油添加剂及其制备方法。
背景技术
为了增加润滑油的减摩抗磨效果,通常在润滑油中添加少量的润滑油添加剂,传统的润滑油添加剂为硫、磷或氯型抗磨剂,此种添加剂对摩擦副材料具有腐蚀性和选择性,特别是含硫、磷或氯等元素的润滑油添加剂在使用过程中,会排放废气和污染物,因而对环境造成污染。
纳米添加剂有助于改善润滑油的性能,而石墨烯作为单层碳原子紧密排列而形成的一种炭质新材料,具有单层二维蜂窝状(Honeycomb)晶格结构,是目前世界上公认的最薄的二维材料,由于其特殊的微观结构,石墨烯具有极好的力学、热导性和电学性能,但现有技术采用N-甲基吡咯烷(N-methyl-2-pyrr0lid0ne,NMP)与石油醚反复清洗以增强石墨烯亲油性的方法,虽然可提高石墨烯在润滑油中的分散性,但其工艺操作复杂繁琐、并且伴有高污染物排放,影响环保。
发明内容
本发明提供的一种石墨烯纳米润滑油添加剂其制备方法,以解决传统的润滑油添加剂存在腐蚀性和选择性问题,纳米材料的添加剂工艺操作复杂,且会排放废气和污染物,对环境造成污染的缺陷。
本发明是这样实现的:
一种石墨烯纳米润滑油添加剂,各组分的含量以重量百分比计包括:
石墨烯0.1-0.8%
油酸1-10%
硼酸酯10-20%
油性溶剂73-90%
其中,石墨烯纳米润滑油添加剂中各组分的含量以重量百分比计优选石墨烯0.2%、油酸2%、硼酸酯15%、油性溶剂82.8%。
其中,硼酸酯的组分以重量百分比计优选2-(4-十二烷基苯氧基)羟乙基胺基二乙氧基硼酸酯40%、2-(4-十二烷基苯氧基)十七烷基胺基二乙氧基硼酸酯20%、2-(4-十二烷基苯氧基)油酸酯羟乙基胺基二乙氧基硼酸酯40%。
其中,油性溶剂优选润滑油基础油。
本发明还提供一种制备上述石墨烯纳米润滑油添加剂的方法,包括如下步骤:取硼酸酯和油性溶剂在温度为50-60℃下充分搅拌30min,再加入油酸,电磁搅拌20min,然后加入石墨烯电磁搅拌30min,最后于300W、20-40Hz的条件下超声处理30min,即得。
本发明的有益效果是:
1、本发明相对传统的硫、磷或氯型抗磨剂,不会出现对摩擦副材料具有腐蚀性和选择性的现象,在生产、使用过程中没有废水、废气、废渣等的产生和排放,是一种环境友好型的绿色润滑油添加剂。
2、本发明使用的硼酸酯组分都是氮化型硼酸酯具有良好的水解稳定性和优异的抗氧化安定性,且该酯增加了添加剂的粘度有利于石墨烯的分散稳定,同时与石墨烯复配有利于该添加剂的极压抗磨性,可起到节油、抗磨、降噪音、提高动力等功能。
3、本发明避免了为增强石墨烯的亲油性使用N-甲基吡咯烷酮与石油醚反复清洗的过程,简化了生产工艺,降低了生产成本。
4、本发明提供的纳米润滑油添加剂可用作多功能润滑油和润滑脂的添加剂,还可以用作各种车辆、船舶、石油化工、矿山的大型机械设备润滑系统的修复抗磨剂。
