Description
Technical field
The present invention relates to lubricating oil composition, in more detail, relate to when containing zinc dithiophosphate, show the lubricating oil composition of low-friction coefficient when using with lubricating oil as low Frictional Slipping material.
Background technology
In recent years, in the various fields, the reply of environmental problem is being become important, advancing about energy-conservationization and the technological development that reduces CO2 emissions.For example, about a raising that problem is an oil consumption of automobile, it is important that the technological development of lubricating oil and sliding material is becoming.
For lubricating oil, be purpose with the various performances that improve in the past, develop various base oils and additive.For example,, suitable viscosity characteristics, oxidative stability, cleaning dispersiveness, abrasion resistance are arranged, press down bubble property etc., seek the raising of these performances through the combination of various base oils and additive as the desired performance of engine oil.Especially, because zinc dithiophosphate (ZnDTP) is outstanding marproofing additive, be usually used in the mover oil additives.
On the other hand, about sliding material, as the material that uses at the very harsh position (for example, the sliding position of mover) of frictional wear environment, the known material that helps to improve wear resistance etc. with ganoine thin films such as TiN film or CrN films.Further, can there be lubricated oil condition decline low-friction coefficient in known diamond-like carbon (DLC) tunicle that utilizes in air, and the material (to call the DLC material in the following text) with DLC tunicle is waited in expectation as low Frictional Slipping material.
Yet DLC material this effect of reducing friction in the presence of lubricating oil is small, is difficult to obtain to save the effect of oil consumption in this case.Therefore, the exploitation of the lubricating oil composition used of in the past low Frictional Slipping materials such as DLC material is being carried out.
For example, disclose in the patent documentation 1 that to contain ether be ashless flow improver, be used for the lubricating oil composition of low Frictional Slipping member.Disclose on the slipping plane of DLC member and iron-based component in the patent documentation 2,3; And on the slipping plane of DLC member and aluminium alloy element, it is that ashless friction improver and fatty amine are the technology of the lubricating oil composition of ashless friction improver that use contains fatty ester.Disclose in the patent documentation 4 in having the low Frictional Slipping structure of DLC coating sliding component, used the technology of the low-friction agent composition that contains oxygen-containing organic compound and fatty amine based compound.
Though the lubricating oil composition that low Frictional Slipping material is used is being developed like this, even use under these technological situation, when pursuing the further raising mixing ZnDTP of wear resistance etc., frictional coefficient but has the tendency of increase.Therefore, be purpose to obtain the lubricating oil that various performances are outstanding, equilibrated is good, even when seeking to contain ZnDTP, also show the lubricating oil composition of low-friction coefficient when using with lubricating oil as low Frictional Slipping material.
