Description
Technical field
The present invention relates to a kind of diesel engine oil composition and uses thereof.
Background technology
Diesel engine oil is made up of base oil and additive.Base oil is lubrication main body of oil, accounts for 70 ~ 80% of oil product component, decides the essential property of lubricating oil; Additive is then the deficiency in order to make up and improve base oil aspect of performance, and giving lubricating oil some new performance, is the important component part of lubricating oil.Due to the progress of base oil process technique in recent years, base oil refining depth is improved constantly, some polar materials in base oil greatly reduce, and while the viscosity-temperature characteristics energy of raising base oil and the susceptibility to some additive, are but declining to the solubility property of additive; In diesel engine oil, the additional proportion of additive is relatively high simultaneously, reaches 10 ~ 30%, and numerous additives joins the hidden danger that can have stability in base oil due to the problem of dissolving; In addition, a large amount of metal additives contained in diesel engine oil are all surfactants, meet the easy emulsification of water electrode and produce precipitation, affect the use properties of oil product.In the middle of storage process, can there is precipitation in various degree because of above various reasons in parts of lubricating oil.If occurred in use with the engine oil of precipitation, the reduction of the partial efficacy such as lubricating oil detergent-dispersant performance energy and antioxidant property directly may be caused.Therefore, the problems of stability in storage of diesel engine oil becomes important all the more in today, and the stable storing improving engine oil can reduce engine to a certain extent and block and increasing service life of engine.
Related work has been carried out both at home and abroad for lubricating oil stability in storage and anti-oxidative stability.Document CN1456646 discloses the preparation method of a kind of lubricating oil and this lubricating oil, to solve storing and the layering in use procedure and sedimentation problem of existing in prior art.But the document is solved by production technique to store and the layering in use procedure and sedimentation problem, has higher requirement to blending instrument and supplies.Document CN1174228 discloses a kind of commonly-used internal combustion engine oil composition, and feature is containing appropriate dinonyldiphenylamine, improves high temperature oxidation resistance, especially to machine oil high temperature retrogradation problem excellent in solution III D testing of engine.Document US 10/158,096 disclose a kind of aminated compounds add can improve controlled oxidization precipitation problem.Document US 10/194,517 discloses and a kind ofly can solve antioxidant property in crankcase oil use procedure and high temperature deposition problem efficiently.But these three sections of documents only relate in by oil oxidation-resistance in use, stressed used engine oil there is sedimentation problem after solution, do not relate to diesel motor fresh oil after having produced, do not use before, the stability problem that occurs in storage process.
Summary of the invention
One of technical problem to be solved by this invention is the problem that in prior art, diesel engine lubricant fresh oil stability in storage is not good enough, provides a kind of new diesel engine oil composition.Two of technical problem to be solved by this invention is to provide a kind of purposes of the diesel engine oil composition corresponding with one of technical solution problem.Use described diesel engine oil composition, under the prerequisite not affecting other performances of diesel engine oil, fresh oil can be made to have better stability in storage.
