Description
Technical field
The present invention relates to lubricating oil composition, relate in more detail anti-friction consumption excellence, particularly can long term maintenance anti-friction consumption low-viscosity lubricating oil composition.
Background technology
In recent years, be background with the environmental problem, cutting down emission amount of carbon dioxide has become the task of top priority, and the consumption improvement of automobile is also improving at present, and oneself becomes important topic for this.Countermeasure for automobile fuel consumption improves makes employed lubricating oil lowering viscousity, and reduce and stir resistance, and, use the friction depressant, the friction that reduces boundary lubrication oil zone all is considered to effectively improve effect.
In low viscous lubricating oil for IC engines, proposed to cooperate the engine oil (for example opening 2001-181664) of high-molecular weight viscosity index saving oil consumption rising agent or that further use friction depressants such as organic molybdenum with reference to the spy.And in the automatic speed variator that torque converter, humid clutch, gear-bearing mechanism, oil pump and oil pressure controlling organization constitute, owing to need make the rubbing characteristics optimization of humid clutch, so do not use the friction depressant of organic molybdenum and so on usually, and think that the lowering viscousity of lubricating oil is effectively, the reduction of the stirring resistance by torque converter or oil pump can be expected consumption improvement.But, the lowering viscousity of lubricating oil, owing to can directly cause the anti-friction consumption to worsen, so consumption improvement and anti-friction consumption that lowering viscousity produces are difficult to get both, and must be that the anti-friction consumption is preferential.
As existing automobile with speed change machine oil, disclose lubricant base, the agent of anti-friction consumption, superpressure agent, metal with synthetic oil and/or mineral oil system and be purification agent, ashless dispersant, friction regulator etc. carry out optimization ground cooperate, as can long term maintenance speed change characteristic etc. the automobile of various performances with speed change machine oil (for example opening flat 3-39399 number, spy with reference to the spy opens flat 7-268375 number, spy and opens the 2000-63869 communique).And as the viscosity index rising agent, usually molecular-weight average is from 1,000～1,000, select in 000 the scope, but as the lubricating oil that cooperates low-molecular-weight viscosity index rising agent, automatic transmission engine oil base oil is as follows disclosed, for example, the number-average molecular weight of using 1～15 weight % simultaneously is that 1,000～10,000 monoolefine polymer or the molecular-weight average of multipolymer and 1～5 quality % are 5, the automatic transmission engine oil base oil of the multipolymer of 000～50,000 the representative examples of saturated aliphatic monohydroxy-alcohol and the ester of methacrylic acid (opening clear 61-9497 communique) with reference to the spy; The number-average molecular weight that contains 3～5 weight % is the semisynthetic automatic transmission engine oil base oil (opening flat 1-168798 communique with reference to the spy) of 26,000～40,000 ethene-alpha-olefin copolymer; Or the number-average molecular weight that contains 27 weight %～34 weight % is the semisynthetic automatic transmission engine oil base oil (opening flat 1-271494 communique with reference to the spy) of 19,000～23,000 polymethacrylate.
But, any in these compositions, because not being is purpose to improve oil consumption, so its kinematic viscosity height, the influence of the antagonism abrasion the when initial stage of the most important problem when making the lubricating oil lowering viscousity and life-time service for conduct, not only do not study fully, do not have fully to study the optimization of viscosity index rising agent and other additive yet.And the automobile on the market is with the kinematic viscosity of automatic transmission machine oil, under 40 ℃, usually at 30～50mm now
2In the scope of/s, therefore think that the low viscosity speed change machine oil of consumption improvement and anti-friction consumption both excellences does not exist in fact.
