Description
Technical field
The present invention relates to field of engine oil, and in particular to a kind of sheet oil additives based on graphene, it can significantly improve and improve the performance of engine oil, and then can reduce fuel consumption and exhaust emissions.
Background technology
It is well known that there is frictional dissipation between the parts of automobile engine motion, this is also the main cause for causing automobile engine to scrap, and being this people is reduced friction loss using including the various ways such as liquid oil lubrication and solid lubrication.But abrasion is still annual to cause hundreds of hundred million yuan of economic loss to country.How reducing friction, reducing abrasion, the service life of extension engine is the target that scientific research technical staff constantly pursues.
It is typically the additive that various antiwear and reducing frictions are added in base oil to improve the greasy property of engine oil.Current antiwear and reducing friction additive mainly has two major classes.One class is oil soluble additive, the oiliness improver of such as polar group, aliphatic acid, phosphorus-containing compound, organic-molybdenum compound.One class is solid additive, such as graphite, molybdenum disulfide with special lamellar structure, tungsten disulfide, boron nitride etc..Especially in the recent period since, it has been found that graphene can greatly improve the performance of engine oil as solid additive relative to traditional graphite：U.S.'s Argonne National Laboratory finds that single layer of carbon atom material has superpower abrasion-resistance, and sustainable more than 6500 wear-out periods, compared with the engine oil that conventional graphite additive is made, its greasy property improves 6.5 times.
But the graphene of structural integrity is the two dimensional crystal combined by the benzene hexatomic ring without any labile bond, chemical stability is high, the inert state in its surface, interacted with other media (such as solvent) weaker, and there is stronger Van der Waals force between the lamella of graphene, easily produce reunion, it is set to be insoluble in water and other conventional organic solvents, if it is directly added in engine oil, precipitation or lamination can be produced during accumulating or use, anti-attrition anti-extreme pressure is reduced, and then harmful effect is produced to machine or equipment, it thus greatly limit the further research and application of graphene.For this, it is typically that graphene is carried out to be added in engine oil again after surface is modified the compatibility for strengthening it with engine oil in the prior art, for example disclose a kind of based on individual layer or the dilute engine oil additive of several layers of graphite in CN101812351A, it is surface-treated to graphene first, then adds in base oil to improve the greasy property of base oil together with dispersant.CN104031716A discloses a kind of engine oil for including graphene, and the graphene is modification graphene, and modified rear and engine oil has good compatibility.
But the technique that graphene is modified is typically complex, and graphene cost after modified is higher, cause to improve as the engine oil cost of additive using it, and then have impact on it and further produce and use, and the generation layering being still difficult to avoid that by modified graphene after long-term storage and use and the phenomenon of sedimentation.
The content of the invention
The present invention is directed to many deficiencies existed based on existing graphene engine oil additive illustrated in technical background（Modified technique is complicated, it is easy to layering and sedimentation), propose that a kind of preparation technology is simple, the good sheet engine oil additive based on graphene of with low cost and greasy property.
In the form of sheets, including main component and auxiliary additive, its main component are graphene to the oil additives, and auxiliary additive is the high polymer material for dissolving in organic solvent.
Preferably, one or more of the auxiliary additive in bicyclic diterpene ketone, alicyclic, phenolate high polymer material.
Preferably, the ratio shared by main component graphene is 75wt% ~ 95wt%.Auxiliary additive proportion is 5wt% ~ 25wt%, more preferably 8wt%-17wt%.
Preferably, a diameter of 10 ~ 24mm of every oil additives, thickness is 5 ~ 12mm, and quality is 50 ~ 400mg.
Invention further provides a kind of preparation method of the sheet engine oil additive based on graphene, this method comprises the following steps：(1) by graphene and auxiliary additive dissolving in organic solvent, it is agitated, be prepared by mixing into additive suspension.(2) suspension for obtaining step (1) filters, dried the powder of obtained graphene-containing.(3) addition tablet is made according to the preparation technology tabletting of conventional tablet in the powder for obtaining step (2).Preferably, described organic solvent is absolute ethyl alcohol.
The sheet oil additives based on graphene that the present invention is provided has the following advantages that：
1. the additive based on graphene of the present invention is in the form of sheets, preparation technology is simple, and only graphene need to be dissolved in into organic solvent is made tablet, and it needs not move through the graphenic surface modified technique of complexity, prepares with low cost.
2. used and transported again difference afterwards with traditional be added to modified graphene in engine oil as additive, the sheet additive of the present invention without being added in engine oil in advance, and it is stable that its performance after Formulation is made, it is easy to store and transports, can be according to different application scenarios, the sheet additive is directly added thereto during engine oil is used, and greatly reduces the storage and transport cost of engine oil.
3. one or more of the auxiliary additive in bicyclic diterpene ketone, alicyclic, phenolate high polymer material selected by the present invention, above-mentioned auxiliary additive can have good compatibility with the base oil of engine oil, and there is good dispersive property to graphene, after sheet oil additives is added in lubricating oil, the presence of auxiliary additive can enable sheet system to dissolve in lubricating oil（By actual test, it is not necessary to which to the operating temperature of engine interior, 60 degree of oil temperature adds stirring, you can be completely dispersed in 2 minutes）And make graphene therein well scattered and be unlikely to produce sedimentation or lamination, the significant greasy property for improving lubricating oil, find after tested, compared with the lubricating oil of other brands both domestic and external, abrasion can not only be reduced by adding the lubricating oil of the additive, lift power performance, increasing service life of engine, the fuel oil that can also save 7-8%, the reduction exhaust emissions amount of engine, and fuel-economizing amount is far above the lubricating oil of other brands.
