摘要

摘要环境问题和矿物油资源的消耗迫使我们开发环保型润滑油。在本研究中，使用四球试验机研究了含有咪唑基离子液体1-乙基-3-甲基咪唑鎓双氰胺（[EMIM][DCN]）（ILa）、膦基离子液体三己基十四烷基膦鎓双（2,4,4-三甲基戊基）次膦酸盐（[P6614][BTMP]）（ILb）和氧化钛（TiO2）纳米颗粒（NP）作为混合添加剂的米糠油的摩擦学性能。用不同浓度的ILa、ILb和TiO2 NP配制米糠油基离子润滑剂。在所有研究的离子润滑剂样品中，米糠油含有0.03的TiO2 NP和0.5 ILa的vol.%显示出最低的AWSD。米糠油基INL特性的改善可归因于滚珠轴承效应和摩擦膜的形成。图形摘要

Tribological evaluation of rice bran oil based ionanolubricants containing ionic liquids and nanoparticles

ABSTRACT Environmental concerns and depleting mineral oil resources have forced us to develop environmentally acceptable lubricants. In this study, tribological properties of rice bran oil containing imidazolium-based ionic liquid 1- ethyl 3methylimidazolium dicyanamide ([EMIM][DCN]) (ILa), phosphonium based ionic liquid Trihexyltetradecylphosphonium bis(2,4,4-trimethylpentyl) phosphinate ([P66614][BTMPP]) (ILb) and titanium oxide (TiO2) nanoparticles (NPs) as hybrid additives have been investigated using four ball tester. Rice bran oil based ionanolubricants (INLs) were formulated with different concentrations of ILa, ILb and TiO2 NPs. Among all investigated ionanolubricant samples, rice bran oil containing 0.03 of TiO2 NPs and 0.5 vol.% of ILa showed the lowest AWSD. The improved characteristics of rice bran oil based INLs can be attributed to the ball bearing effect and tribofilm formation. GRAPHICAL ABSTRACT
