Description
Technical field
The present invention relates to a kind of engine oils additives, more specifically, relate to a kind of additive that is used to improve the high temperature detergent performance of engine motor oil.
Background technology
Along with improving constantly of engine lubrication oil quality, people are also more and more stricter to its every index request.High temperature detergency more and more is subject to people's attention as an important index of lubricating oil, now as the necessary means of estimating high-grade I. C. engine oil.Along with high temperature detergency becomes the very important index of the especially high-end engine oil of engine oil, focus that the high temperature detergent-dispersant performance becomes gradually also that people pay close attention to and developing direction.
A series of variations such as oxidation, polymerization, condensation take place in engine oil under high temperature action, produce carbon distribution, paint film and greasy filth in top, side and the bent axle of engine piston.These sedimentary generations are very big to the piston lubrication and the influences such as thermal conduction and pinking, igniting of engine, seriously undermined work-ing life, the engine power of lubricating oil and the consumption that has increased fuel.The high temperature detergency of lubricating oil evaluates lubricating oil oil product dissolving after forming oxidation products exactly, disperses, in and abilities such as oxidation products, inhibition paint film, carbon distribution generation.
The method of improving high temperature detergency now mainly is by adding salicylic salt, wherein salicylic magnesium salts and calcium salt have certain effect to the high temperature detergency that improves engine motor oil, in addition, use the oxidation inhibitor of some phenyl aminess also to demonstrate the improvement of high temperature detergency.
At present, still need a kind of means that can further improve the high temperature detergency of engine motor oil.
