For lubricating oil, to improve for the purpose of various performances in the past, developing various base oil and additive.Such as, as the performance required by engine oil, there are suitable viscosity characteristics, oxidative stability, clean dispersiveness, abrasion resistance, press down bubble property etc., sought the raising of these performances by the combination of various base oil and additive.Especially, because zinc dithiophosphate (ZnDTP) is outstanding marproofing additive, therefore engine oil additives is usually used in.
On the other hand, about sliding material, as the material that the position (such as, the sliding position of engine) very harsh at frictional wear environment uses, there will be a known the material with the ganoine thin film such as TiAlN thin film or CrN film contributing to improving wear resistance etc.Further, knownly utilize diamond-like carbon (DLC) tunicle, can in atmosphere, there is not lubrication oil condition decline low-friction coefficient, the material (hereinafter referred to as DLC material) with DLC tunicle is expected to as low Frictional Slipping material.
But the effect of DLC material this minimizing friction under the existence of lubricating oil is small, is in this case difficult to obtain the effect of saving oil consumption.Therefore, the exploitation of the lubricating oil composition of the low Frictional Slipping material such as DLC material in the past is carried out.
For example, Patent Document 1 discloses containing the ashless flow improver of ether system, for the lubricating oil composition of low Frictional Slipping component.Disclose in patent documentation 2,3 on the slipping plane of DLC component and iron-based component, and on the slipping plane of DLC component and aluminium alloy element, use the technology of the lubricating oil composition containing fatty acid ester system Ashless friction modifiers and fatty amine system Ashless friction modifiers.Patent Document 4 discloses in the low Frictional Slipping structure with DLC coating sliding component, use the technology of the low-friction agent composition containing oxygen-containing organic compound and fatty amine based compound.
Although the lubricating oil composition of low Frictional Slipping material is developed like this, even if when applying these technology, for pursue the further raising of wear resistance etc. and mix ZnDTP time, frictional coefficient but has the tendency of increase.Therefore, for the purpose of the good lubricating oil obtaining various excellent performance, balance, even if seek, containing while ZnDTP, also to show the lubricating oil composition of low-friction coefficient when using as low Frictional Slipping material lubricating oil.
