(B) High viscosity synthetic oil with kinematic viscosity of 40mm at 100 deg.C2The hydrocarbon-based synthetic oil having a composition of at least one kind selected from the group consisting of 1 or 2 kinds of alpha-olefin oligomers, hydrides of alpha-olefin oligomers, and ethylene-propylene co-oligomers.
Description
Technical field
The present invention relates to lubricating oil composition, the energy saving that especially the fluid friction coefficient in the high and elastohydrodynamic lubrication field of viscosity index is low, economize the lubricating oil composition of burnup excellence.
Background technology
The original object of lubricating oil is, by the oil film forming at sliding position place, reduces friction.Therefore, form stronger oil film, lubricating oil is that high viscosity is more favourable.But so, the needed power of the stirring of lubricating oil or oil supply can become larger power loss, be an impediment to and improve energy saving, province's burnup.Therefore in recent years, in order to reduce power waste, the lowering viscousity of lubricating oil carries out.
Yet, if make the excessive lowering viscousity of lubricating oil, during high temperature, be difficult to form oil film at sliding position, therefore can there is the situation that increases friction or cause abnormal abrasion.
In full-bodied situation when therefore, requirement can maintain high temperature, reduce the viscosity in conventional temperature province.This just means extremely to reduce the oil body of temperature variation is changed, represent to need viscosity indexs (high VIization) extremely lubricating oil.
On the other hand, in most mechanism, as element, use and have the rolling bearing of rotational motion of support or the gear of transferring power.The lubricated part of these rolling bearings or gear is in elastic fluid lubricating status, and frictional coefficient is herein called as drag coefficient.Therefore,, in order to reduce the frictionloss in the mechanism in such lubricating status, just need to carry out low traction (reduction drag coefficient) to lubricating oil.
Yet, want to reduce this drag coefficient and be not easy, especially, when thering is high viscosity index, reduce again drag coefficient and be not easy.
Now, when attempting to solve such raising viscosity index, reduce the problem of drag coefficient, can enumerate for example patent documentation 1.
In above-mentioned patent documentation 1, the tractive coefficient of the lubricating oil composition that a kind of reduction contains the basic raw material (base stock) in 100 ℃ with the viscosity that is greater than 3cSt is disclosed, reduce the method for drag coefficient, it is to add the method that traction subtracts power agent, as traction, subtract power agent, record (with reference to patent documentation 1 claims 1,4) such as monobasic acid esters.And, also recorded the lubricating oil composition that improves viscosity index, reduces drag coefficient.
Yet the effect of the drag coefficient of the reduction lubricating oil composition of recording in patent documentation 1 is not necessarily abundant, also needs further to improve reduction tractive coefficient, be the effect of drag coefficient.
