Description

一种含石墨烯的高耐磨环保节能发动机润滑油及其制备方法
技术领域
本发明涉及一种发动机润滑油及其制备，尤其涉及一种含石墨烯的高耐磨环保节能发动机润滑油及其制备方法。
背景技术
润滑油在航空、汽车、机械加工、交通运输、冶金、煤炭、建筑、轻工等行业也有着极为广泛的应用。随着工业的高速发展，润滑油的需求量逐年攀升。而传统的以矿物油为基础油的润滑剂，不仅污染了环境，同时也加剧了能源枯竭。在其被大量使用的同时，不可避免地会通过运输、泄露、溅射、溢出或不恰当的排放等多种途径流入环境，严重污染着土壤和水资源，破坏生态环境和生态平衡。绿色润滑油又称为环境友好型或环境兼容型润滑油，其包括两方面的含义：一是其使用性能必须满足工况要求；二是生态效应，即其本身及其分解产物不会对生态环境造成危害，或在一定范围一定程度上对环境是友好的。
石琛在其博士学位论文《纳米WS2环保节能发动机润滑油的研制及其性能研究》中，利用菜籽油、聚α烯烃PAO6、多元醇酯PriEco3000和WS2制备了一种发动机润滑油，但是其承载能力、抗磨能力还有待提高。
发明内容
基于以上的思考，本发明旨在提供一种具有高承载性能、高耐磨性能的环保节能发动机润滑油及其制备方法。
本发明所要解决的技术问题采用以下的技术方案来实现 ：
一种含石墨烯的高耐磨环保节能发动机润滑油，其特征在于，由以下重量份的原料制成：
石墨烯1-3，菜籽油50-70，石油醚2-4，聚α烯烃PAO6 15-25，多元醇酯PriEco3000 6-15，氮化硼1-2，硫粉4-8，钨粉0.5-1，沸石ZIF-8 5-10，亚油酸2-3，二甲基亚砜15-20，降凝剂LZL803B 5-10，乙丙共聚物T618 4-7，去离子水15-20，无水乙醇适量。
所述的一种含石墨烯的高耐磨环保节能发动机润滑油及其制备方法，其特征在于，由以下步骤制成：
a. 将硫粉和钨粉相混合，形成混合物，使该混合物在110-260℃的温度下进行反应，再将反应物在500-700℃的温度下于非氧化气氛中进行结晶，即得到二硫化钨粉末和剩余的硫粉混合物；
b. 将步骤a所得混合物、石墨烯、氮化硼与去离子水混合，加入亚油酸，得到悬浮液，在强超声场中采用球磨搅拌处理悬浮液8-12h后取料，冷冻干燥得到超细二硫化钨与硫、石墨烯、氮化硼混合物粉末；
c. 将步骤b所得混合物粉末分散于二甲基亚砜溶剂中，并向其中加入沸石ZIF-8，搅拌均匀后转入聚四氟乙烯反应釜中，在80-120℃条件下放置5-10天后，过滤并用无水乙醇洗涤2-4次，室温干燥后，得到吸附超细二硫化钨和硫粉末，并有二甲基亚砜填充的沸石ZIF-8混合物；
d. 将菜籽油、石油醚、聚α烯烃PAO6、多元醇酯PriEco3004混合，加入降凝剂LZL803B、乙丙共聚物T618、步骤c所得混合物，转入搅拌机中搅拌30-90min即可。
所述的一种含石墨烯的高耐磨环保节能发动机润滑油及其制备方法，其特征在于，搅拌机的转速为200-400r/min。
本发明的有益效果是：本发明利用强超声和球磨搅拌的复合作用，使二硫化钨悬浮颗粒粒度接近纳米二硫化钨颗粒粒度，再通过亚油酸对颗粒表面进行修饰处理，有效防止了颗粒间的重新团聚，从而使二硫化钨颗粒在基础油中保持稳定分散，提高了其稳定性；引入憎水亲油材料沸石ZIF-8，并用二甲基亚砜浸泡，不仅可以将沸石ZIF-8作为二硫化钨颗粒的载体，进一步提高其与基础油的融合性，同时沸石ZIF-8可作为优良的润滑添加剂，和二硫化钨一起用以增强润滑油的承载能力和抗磨减摩能力，而二甲基亚砜则促进了沸石ZIF-8载体与润滑油的融合能力。通过菜籽油作为主体基础油，提高了该润滑油的环保性能，环境友好；通过添加石墨烯有效增加了润滑油的抗磨擦性能并降低了发动机的损耗。
