Description
Technical field
The present invention relates to a kind of engine lubricating oil.
Background technology
Lubricating oil be used in all kinds automobile, in plant equipment with reduce the liquid of rub protection machinery and workpiece or
It is semi-solid.Lubricating oil mainly plays lubrication, cooling, antirust, cleaning, sealing and buffering etc..Lubricating oil typically by base oil and
Additive two parts form.Base oil is that the main component of lubricating oil decides the fundamental property of lubricating oil, and additive then can be more
The deficiency for mending and improving base oil aspect of performance assigns the important component that some new performances are lubricating oil.
Additive is the marrow of modern age senior lubricant.It is correct to improve its physicochemical properties from rationally addition,
Certain performance that new property or reinforcement its original are assigned to lubricating oil to be had makes it meet higher requirement.According to lubrication
It is to ensure the pass of quality of lubrication oil that the selection meticulous to additive of quality and performance and careful balance that oil requires, which carry out rational allocation,
Key.But China existing additive is mainly divided by function at present, single dose in terms of the functions such as anti-oxidant, wear-resistant, cleaning all
There is outstanding performance, but be provided simultaneously with multi-functional monomeric additive prior art and unknowable, addition on the market
Agent is typically all the combination product of each single additive, different be exactly single additive composition is different and multi-functional addition
The ratio of several single additives is different inside agent, and additive stability is poor.
With the fast development of industrial technology, lubricating oil and its additive are also developed very well.Added for lubricating oil
For agent, high temperature resistant, environmental protection, efficiently and pleiotropism by be future development direction.Nitrogen-containing heterocycle compound, such as benzo three
Nitrogen azoles, alkyl substituted imidazole quinoline, 2,5- dimercapto -1,3- thiadiazoles and its derivative are all widely known lubricating oil antirusts
Agent, antioxidant and anticorrosive, some derivatives also have good extreme pressure and antiwear behavior.Due to they have small toxicity,
The features such as ashless, so domestic and foreign scholars are just studied them since the beginning of the eighties, synthesize successively much same
The azacyclo- function with compact texture is talked and the group of active element containing extreme-pressure anti-wear in molecule（Sulfur-bearing, phosphorus, chlorine etc. organise
Compound）The Hete rocyclic derivatives being combined, and their friction and wear behavior and anti-oxidant and Corrosion Protection is studied.
With the development in big machinery field, for big-block engine using more and more extensive, high-power engine has higher calorific capacity,
Engine temperature is higher, and lubricating oil evaporation loss is big, easily occurs aoxidizing or nitration reaction, increase greasy filth and carbon deposit, acceleration are sent out
The problems such as motivation abrasion, deterioration of lubricant aging.Lubricating oil is under high temperature action, and its chemical stability is deteriorated, and various functions are such as
Anti-oxidant, wear resistance decrease.
The content of the invention
The shortcomings that in order to overcome available engine lubricating oil to exist, the present invention supply a kind of cylinder oil, the profit
The oxidation resistance and abrasion resistance of lubricating oil are good, effectively reduce the evaporation loss of lubricating oils, and spatter property is good, reduce greasy filth
And carbon deposit.In order to reach the technique effect, the content of the invention：
A kind of engine lubricating oil, it is characterised in that：A kind of engine lubricating oil includes the group of following parts by weight：
70 ~ 90 parts of base oil,
0.01 ~ 5 part of multifunction additive,
0.1 ~ 5 part of detergent-dispersant additive,
0.1 ~ 5 part of viscosity index improver,
0.08 ~ 3 part of pour-point depressant；

Specific embodiment
It is of the present invention with multifunction additive be a kind of carbamate compounds containing ferrocene group be the present invention
Prepared by synthetic method, synthesis material used and other base oils, additive etc. commercially have sale.
Without special instruction, preparation method of the present invention is this area customary preparation methods.
Ferrocene is excellent combustion supporting catalyst, and it can not only reduce the carbon deposit of dynamic power machine combustion chamber, prolonged mechanical
Service life, while fuel availability can be improved, reduce pollution of the flue dust to air.Ferrocene is also known as bicyclic luxuriant dialkylene iron,
It is a kind of metallo-organic compound with interlayer structure, not soluble in water at normal temperatures in orange crystal shape, is soluble in bavin
The organic solvents such as oil, gasoline, benzene, ethanol, chemical property is stable, tasteless nontoxic.Ferrocene and its derivative is because of the spy of itself
Point, such as hydrophobicity, biological oxidability, armaticity, stability, hypotoxicity, bioactivity, and be widely used.As disappearing
Cigarette additive for saving energy is usually used in the liquid fuels such as gasoline, diesel oil, heavy diesel fuel, to saving the energy, reduction flue dust, preventing the pollution of the environment
There is positive effect, thus can be widely applied to various tractors, scraper, truck and diesel locomotive etc..Add into diesel oil
Enter a certain amount of ferrocene, smoke-eliminating combustion-aid, and then an oxygen in the exhaust smoke level of reduction diesel engine and tail gas can be played a part of
Change the content of carbon, mitigate pollution of the emission to environment, strengthen the power of engine.In addition, ferrocene can also eliminate diesel oil
Power traction holds up the deposition charcoal of combustor surface, and can deposit one layer of iron oxide film on its surface, effectively prevent the weight of carbon granule
New deposition.Ferrocene and its derivative is added in gasoline, the octane number of gasoline can be not only improved but also enhance anti-knock properties
