Description
Technical field
The present invention relates to a kind of engine oils additives, start for improvement more particularly, to one
The additive of the high temperature detergent performance of machine machine oil.
Background technology
Along with improving constantly of engine lubrication oil quality, its indices is required more and more tighter by people
Lattice.High temperature detergency, as an important index of lubricating oil, is increasingly subject to people's attention,
As the necessary means evaluating high-grade I. C. engine oil.Along with high temperature detergency, to become engine oil the highest
The end very important index of engine oil, high temperature detergent-dispersant performance is increasingly becoming of concern one
Individual focus and developing direction.
A series of changes such as engine lubricating oil aoxidizes under high temperature action, is polymerized, condensation, are sending out
The top of motivation piston, side and bent axle produce carbon distribution, paint film and greasy filth.These sedimentary generations
Very big on the piston lubrication of electromotor and conductivity of heat and the impact such as pinking, igniting, seriously undermine lubricating oil
Service life, engine power and increase the consumption of fuel.The high temperature detergency of lubricating oil is commented exactly
Determine lubricating oil oil product after forming oxidation product to dissolve, disperse, neutralize oxidation product, suppression paint film, amass
The abilities such as carbon generation.
Improve now the method for high temperature detergency mainly by adding salicylic salt, wherein salicylic acid
Magnesium salt and calcium salt to improve engine motor oil high temperature detergency have certain effect, it addition, use one
The antioxidant of a little phenyl aminess also shows that the improvement of high temperature detergency.
At present, it is still necessary to the means of a kind of high temperature detergency that can improve engine motor oil further.
Summary of the invention
It is contemplated that a kind of new engine oils additives, it can significantly improve engine motor oil
High temperature detergent performance.
Therefore, a first aspect of the present invention relates to a kind of engine oils additives, and it comprises at least one
The salicylate of boron modification and at least one alkyl diphenylamine.
It was found by the inventors of the present invention that by the salicylate of boron modification and compounding of alkyl diphenylamine, can
To obtain the high temperature detergent performance exceeded far away than single additive.
It addition, the engine oils additives of the present invention is when actually used, it is possible to use base oil is carried out
Dilution, still possesses the most excellent effect.
The method that the invention still further relates to improve the high temperature detergent performance of engine motor oil, wherein at engine oil
After replacing, the engine oils additives of the present invention is added in engine oil.
Use the engine oils additives of the present invention, improve engine oil in terms of high temperature detergency
Performance, and reduce engine noise, increasing service life of engine.
Detailed description of the invention
The composition of the engine oils additives of the present invention is described below in detail.
