Description
Technical field
The present invention relates to a kind of lubricating oil preparation methods, and in particular to a kind of carbon nanomaterial lubricating oil preparation method.
Background technology
Friction and wear is the main reason for causing mechanical failure, every year the part material as caused by mechanical friction and abrasion
Lost value is up to hundreds of hundred million yuan, increases severely especially as China's automobile usage amount, the fast development of high ferro and steamer industry, present situation is more
Step up to compel, it is to reduce to lose effective approach to reduce engine and train abrasion.Lubricating oil, which can play, reduces mechanical surface phase
Mutual friction, extruding, impact or the effect of other surfaces failure mode, therefore, quality of lubrication oil is most important in machinery industry.
In the case of mechanical wear occurs mainly in boundary lubrication, lubricating oil is formed by oil film often quilt in friction surface at this time
Break, for this purpose, often using graphene as additive, increases wear resistence and extreme pressure property.Graphene has ultra-thin lamellar structure (easily
Engaging friction contact surface), excellent mechanical property and self lubricity, these characteristics so that its application in terms of lubricating additive is ground
Study carefully and attract attention, numerous studies find that suitable graphene can not only reduce friction coefficient, Er Qieneng as lubricating additive
The carrying abrasion resistance of lubricant is significantly improved by the form of friction clamping film.But graphene group of easy ting produce in lubricating oil
Poly- phenomenon, to affect its dispersion stabilization in lubricating oil and solvent.
Currently, at present graphene as additive in lubricating oil apply there are the problem of：
First：Conventional graphite alkene is additive-treated oil, and graphene preparative separation, purification process are complicated.
Preparing graphene method such as mechanical stripping method, vapour deposition process, epitaxial growth method can not mass produce, Er Qiegong
Skill is complicated, yield is small；And chemistry redox method equally faces and isolates and purifies complicated difficulty, and oxygen-containing functional group can lead to graphite
Friction coefficient increases when alkene interfacial friction, and atomic structure of carbon destroys in layer, greatly reduces the tribological properties of graphene.Therefore
It need to be isolated and purified as lube oil additive, lock out operation is complicated difficult, and loss amount is big.
Second：Merely using graphene as under additive-treated oil high load capacity, sliding, which squeezes, causes graphene sheet layer to stack, nothing
Method plays lubricating action.
Single use graphene can not effective protection contact surface；Under high load capacity, because huge extruding force protects graphene
Membrane pressure reality densification is stacked between graphene layer and is difficult to scatter, and not only graphene protective film is destroyed, and long-term stack can make stone
Black alkene grain size becomes larger and becomes abrasive grain, and rubbing surface is scratched in the secondary sliding process of friction.
Invention content
For use of the carbon nanomaterial in lubricating oil come prepare new lubricant there are the problem of, the present invention using electricity
Arc method prepares different component carbon nanometer additive by parameter adjustment；To be prepared into different performance lubricating oil.
Present inventive concept has as shown in Fig. 1：
Different component carbon nanometer additive is prepared by adjusting technological parameter, reaches control carbon nanomaterial preparation process, adjustment
Lubricants performance.
Under atmosphere appropriate, by the different proportions such as hydrogen, helium, nitrogen or ammonia atmosphere to the shape of carbon nanomaterial
State has a significant impact.Therefore, this method is regulated and controled by arc process parameter, prepares different component carbon nanomaterial additive, to
Adapt to lubricants performance demand under different operating modes.
When a large amount of carbon nanotubes and a small amount of graphene are as additive, its tubular structure of a large amount of carbon nanotube is negative in height
Under the conditions of lotus, ball bearing can be played the role of, surface abrasion can be reduced；Graphene a small amount of simultaneously exists, and ensure that profit
Lubricating oil has certain anti-extreme pressure energy.
When a large amount of graphene and a small amount of carbon nanotube are as additive；Under extreme pressure operating mode, mechanically supported power is excessive, rubs
It wipes surface and deposited a large amount of graphene, rock-steady structure stabilization cannot react with metal, reduce scratches on metal surface, burn
Knot, shows excellent extreme pressure property.Carbon nanotube a small amount of simultaneously is played a supporting role.
The present invention adopts the following technical scheme that：
Step 1：Arc furnace current 130A is set, and voltage 380V, using high purity graphite as carbon source, high purity graphite rod is as electric arc furnaces
The two poles of the earth, with H2With He gaseous mixtures be reaction atmosphere, stagnation pressure 73KPa, control reaction atmosphere in 3.65 KPa of hydrogen partial pressure ~
18.25 KPa, the carbon nanomaterial obtained after reaction, the carbon nanomaterial A0 obtained after reaction；
Step:2：Modifying agent is distributed in isooctane and is configured to modifier solution, modifying agent quality and isooctane volume ratio
For 0.01-1g/ml, ultrasound makes it be uniformly dispersed；
Step 3：Carbon nanomaterial is added and is modified by the ratio that 5-100 grams of carbon nanomaterial is added according to every liter of modifier solution
Mixed solution is obtained in agent solution, ultrasonic disperse is uniform, then mixed solution is transferred in vacuum impregnation experimental provision, 20
DEG C, suction to 0.1MPa, suction time 30min；Then it keeps closed, is heated to 80 DEG C, impregnate 2 ~ 12h；Then it keeps
Suction to 0.1MPa and to 80 DEG C, continue concentrate mixed liquor, until liquor capacity be initial volume 1/6-1/20 to get to
Modified carbon nano tube material lubricant concentrate B0；Modified carbon nano tube material lubricant concentrate B0 is added in base oil, it is modified
Carbon nanomaterial concentrate B0 mass accounts for the 0.1-2% of carbon nanomaterial lubricating oil gross mass；It is stirred at 40 DEG C~70 DEG C of temperature
Uniformly to get carbon nanomaterial lubricating oil.
Modifying agent described in step 2 is succimide type ashless dispersant, single polyisobutene butyric acid imines, double focusing isobutyl
Two phthalimide of alkene fourth, poly isobutene fourth diphenol imines, boronation high molecular weight polyisobutylene succimide, high molecular weight fourth two
Acid imide one of which or two or more combinations；The molecular weight of the succimide type ashless dispersant preferably 1000 ~
10000。
Base oil described in step 3 is one or more in synthetic base oil, mineral base oil.
Technology explanation
Step 1 explanation：It is that carbon material does not have that arc process, which prepares carbon material and does the maximum difference of the carbon material prepared with conventional chemical methods,
There is the phenomenon that reunion is lumpd, carbon material is fluffy, large specific surface area.
Step 2 explanation：The formation of single-walled carbon nanotube (SWNTs) and graphene is considered as two independent processes, H2
It can be connected with the edge of carbon cluster and terminate carbon dangling bonds, to prevent the formation of closing carbon structure, keep carbon nanotube tight with other
The formation of close carbon structure minimizes；Some inert gases such as He is additionally added, inert gas plays the role of " quenching " agent,
It is also critically important to graphene quality, suitable H is selected thus2Concentration.Therefore, by adjusting H in mixed buffer gas2Point
It presses to adjust the component of synthesizing graphite alkene and SWNTs.Work as H2When less than 3.65KPa, H2Concentration it is relatively low, close the shape of carbon structure
As mainly to form a large amount of SWNTs, keeping the carbon atom to form graphene fewer and fewer, generate seldom graphene platelet；
Work as H2When partial pressure is more than 18.25KPa, excessive hydrogen is utilized, and prevents the formation of carbon nanotube, will produce a large amount of stone thus
Black alkene and generate seldom SWNTs.Therefore, according to H2It influences, adjusts the partial pressure of hydrogen and contain to control generation SWNTs and graphene
Amount.
Step 3 explanation：Succimide type dispersant has molecular weight big, so viscosity is also big, for ensure modifying agent with
Carbon nanomaterial uniform adsorption is diluted with a large amount of isooctane, reduces modifying agent viscosity, increases mobility.
Step 4 explanation：Make modifying agent fully adsorb in the step of the invention to be wrapped in carbon material surface, there is following spy
Point,（1）This step vacuumizes at room temperature, and isooctane will not largely gasify, and system is caused negative pressure occur, and carbon material surface is adsorbed
Air and solution in remaining gas be extracted, so that imidodicarbonic diamide type modifying agent is come into full contact with carbon material surface；
（2）80 DEG C are warming up to, increases as temperature increases molecular thermalmotion, is more advantageous to the polarity of succimide type modifying agent
Group is adsorbed with carbon material surface；And keep under 80 DEG C of air-tight states, isooctane is in gas-liquid mixture phase, and imidodicarbonic diamide type changes
Property agent concentration increase, so that imidodicarbonic diamide type modifying agent is fully reacted with carbon material surface.After reaction, as isooctane gas is gradual
Isolated at suction, gas solid separation can be more preferable to ensure solid pattern to avoid the influence for filtering, centrifuging；
（3）Concentration mixed liquor terminates vacuum state to the 1/6-1/20 that liquor capacity is initial volume, that is, ensure that carbon nanometer material
Sufficient absorption and package of the material with modifying agent, and maintain the fluffy pattern of carbon nanomaterial that arc process is prepared.Obtain
Modified carbon nano tube material lubricant mother liquor, at this time modified carbon nano tube material surface fully adsorbed modifying agent, there is excellent point
Property is dissipated, the 0.1-2% that mother liquor quality is finally accounted for carbon nanomaterial lubricating oil gross mass is added in base oil, when mother liquor uses
When amount is less than 0.1%, carbon nanomaterial additive amount is very few can not to form complete carbon protective film, and lubricant effect is bad, when additive amount mistake
Greatly, winding stacking can occur for excessive carbon nanotube and graphene, formed and generate abrasive grain, do not play lubricant effect not only, add instead
Big abrasion.
Advantageous effect
1, the present invention adopts arc process and prepares carbon nanomaterial, and the preparation of graphene is carried out not over the mode of separation, purifying, and
It is the regulation and control by parameter, prepares the additive integration means of different " impurity " ratios, to obtain different performance lubricating oil,
Both simplify corresponding purifies and separates technique, be improved the quality of lubricating oil；
2, the present invention is by way of first disperseing to be concentrated in vacuo afterwards, solves that high concentration modifier solution viscosity is big, dispersion is uneven
It is even, and a small amount of modifying agent of low concentration modifier solution reacts insufficient contradiction with carbon nanomaterial；
3, the present invention prepares carbon nanomaterial lubricating oil, has good dispersion stabilization, is observed by the standing up to 1 year,
It still keeps intact, there is very excellent stability, also effectively improve the wear resistence and extreme pressure property of lubricating oil；As addition exists
It is used in engine lubricating oil, engine noise can also be reduced, reduce engine idling, it is more fuel-efficient.
