Description
The invention belongs to the preparation field of mechanical movement with the lubricating oil medium.Be specially adapted to the manufacture method of employed abrasion-proof lubricant oil of automobile industry and this lubricating oil.
In daily life or in producing, use automobile or machinery to be absolutely necessary, and power lubrication is mechanical movement and safeguard indispensable integral part.In the friction surface role, the lubricated of mechanical component can be divided into two types: hydrodynamic lubrication and boundary lubrication according to the working conditions of friction parts and lubricating oil (ester).Under Liquid Lubrication Condition, reduce lubricating oil viscosity and just can reduce friction energy loss, but under condition of boundary lubrication, the reduction effective way that rubs is to select slip additive rightly.
Extreme pressure anti-wear additives and friction improver.Traditional antifriction, anti-wear agent can be divided into two classes: a class is oil soluble organic compound (comprising organometallic compound), and another kind of is the molten solid lubrication additive type of non-oil.The oil soluble organic compound comprises: sulfur-bearing in the molecule commonly used, phosphorus, chlorine isoreactivity element as with olefine sulfide, phosphoric acid ester and clorafin be do not contain in the extreme pressure anti-wear additives, organic molecule of representative the extreme pressure anti-wear additives of active element such as organic boron that developed recently gets up and by discovery such as Furey by dimeracid and pure a kind of recombiner of forming; Organometallic compound comprises: simple organometallic compound such as lead naphthenate, be the organometallic compound that contains active element of representative and oil-soluble organic molybdenum etc. with the zinc dialkyl dithiophosphate.The oil soluble organic compound can mix with lubricating oil (ester) in its solubility range, can improve the quality of lubricating oil (ester).But the oil soluble organic compound is easy decomposition and consumption when comparatively high temps, supporting capacity is low, and also may corrosive nature be arranged to the bearing of non-ferrous metal (silver, tin), when having the organic compound that adopts active element to make slip additive again, though sulphur, phosphorus, chlorine are the key elements of lubricate, oil base antifriction, the anti-wear agent of sulfur-bearing, phosphorus, chlorine are not only harmful, and contaminate environment, as phosphoric the catalytic converter that automobile installs is poisoned, thereby influence the discharging of automobile; The anti-wear agent such as the organic boron additive that do not contain active element are easy to lose lubricating function because of hydrolysis.And solid lubrication additive, as MoS commonly used
2Though graphite, PTFE, pottery etc. have certain lubrication, the main drawback of these solid lubrication additives to be, because the solid powder particle degree is bigger, dispersion instability in lubricating oil, or the reasons such as dissolubility difference of holding concurrently with oil product make product not reach ideal effect in use.
The objective of the invention is to propose a kind ofly have wear-resistant, antifriction, repairing effect is good, and mechanical part is not had the sintering metal lubricant and the manufacture method thereof of corrosive nature and environmental protection.
According to purpose of the present invention, the solution that we proposed be with nano metal powder be evenly dispersed in again in the carrier oil body after nano ceramic powder mixes, make nanometer powder in carrier oil, form stable suspensoid.According to above-mentioned principle, our designed sintering metal lubricant is to be combined by slip additive and carrier fluid, the weight content per-cent that it is characterized in that sintering metal lubricant each component is respectively: slip additive content is 5-15%, dispersion agent and carrier fluid content are 85-95%, and wherein the content of solid powder in slip additive and dispersion agent is respectively:
Metal-powder---2.5%-14.25%;
Ceramic powder---0.5%-2.5%;
Dispersion agent---0.5%-1.5%.
In sintering metal lubricant of the present invention other features also have slip additive be by solid powder in metal powder material and ceramic powder be nanopowder, behind Nano metal powder and nano-ceramic powder and dispersion agent uniform mixing, form.
Carrier fluid is meant any one lubricating oil in mineral oil, PAO and the diester in the sintering metal lubricant.Nano metal powder in solid powder is meant iron powder, brown iron oxide, mixes with any one nano-ceramic powder after any one in copper powder, zinc powder, iron alloy powder and the copper alloy powder or two kinds of combinations again.Nano-ceramic powder in solid powder is meant that in carborundum powder, silicon nitride powder, bortz powder and silicon carbide and the diamond powder mix any one becomes with nano metal powder combined group.Dispersion agent in slip additive is meant any one in salt, A3 long-chain polyamino amidophosphoric acid salt, A4 polymeric polycarboxylic acid salt, A5 glycerin fatty acid phosphoric acid and the A6 diethanolamine of fat acyl of A1 long-chain polyamino acid amides, A2 polymer acid esters.
The manufacture method and the prior art of sintering metal lubricant of the present invention are basic identical, at first solid powder in the slip additive is mixed with carrier fluid oil ball milling by setting content and after dispersion agent mixes again, then through liquid stream pulverizing, centrifuging and Performance Detection, it is characterized in that metal nano powder mean particle size is 20-40nm in the solid powder, the mean particle size of nano ceramics powder is 30-45nm.
The basic functional principle of sintering metal lubricant of the present invention be with solid nano sintering metal powder by hybrid mode, be scattered in equably in the carrier oil and formed stable suspension system.In sintering metal lubricant of the present invention, when an amount of nanometer lubricating additive adds in the plain oil (ester), nano particle is because granularity is very little, engaging friction surface very easily, these particles become rolling resistance with sliding friction as " ball bearing " on the microcosmic, greatly reduce friction resistance, the surfactivity that nano particle is huge can form higher, the thicker oil film of intensity, and surface of friction pair can be separated well, thereby has improved the wear-resistant and friction reducing effect of plain oil (ester) greatly; Because nano particle has higher surface activity, also can make particle directly be adsorbed onto cut or repair has been located in little hole, and can be according to the reparation amount how much come to determine its addition, overcome organic compound and in lubricating oil (ester), be subjected to solubility limit, restricted the drawback that a large amount of reparation products generate as reactant.Nano-metal particle is also because its coefficient of expansion and most of metal are approaching in nano metal, the ceramic-like slip additive; when it attached to friction pair on the time; can not produce the tolerance variation that temperature causes; it is overheated that good thermal conductivity also can guarantee to produce at the Shi Buhui that runs up; and can mate with low viscosity oil; the existence that still can keep lubricant film under the condition of high capacity and vibration is particularly suitable for work under heavy duty, high (low) speed, high (low) temperature and vibration condition.In addition, because nano particle is to be scattered in the oil (ester) with similar colloidal form, so when lubricating oil miss or for a certain reason (as strong extruding etc.) grease is lost, the nano particle that is deposited on the friction surface still can play lubrication in considerable time.
Draw by test, after the nano metal of employing plain oil adding 5%, nano ceramics (Nano diamond) slip additive, its fastness to wear increases substantially, the rupture of oil film intensity P of lubricating oil
BValue is brought up to 100～102kgf by original 98.5kgf, attrition value d
30 120Being dropped to below the 2mm by 2.283mm, add the attrition value of proper amount of nano metal, ceramic powder slip additive even 1.315mm is only arranged, is 2.203mm and add the attrition value of micron-sized metal additive (contrast oil sample) this moment; At load value is 120Kgf, lubricated after 10 minutes, under 10 minutes the condition of oil-break continuity, be about 6 minutes the perdurability of plain oil (Great Wall SE15W/40 machine oil), and same machine oil perdurability of adding 5% nanometer lubricating additive generally all more than 20 minutes, reach as high as more than 40 minutes.
Adopt sintering metal lubricant of the present invention compared with prior art, have superpower lubrication, reduced the engine interior resistance significantly, engine idle improves 20%, and starting current descends 3%, and the temperature of engine and noise also obviously reduce; And the nano particle in the additive, because the scratch that can repair friction surface automatically, reduced old engine and eaten the machine oil phenomenon, obnoxious flavour CO value drops to 0.74%, four cylinder cylinder by 3% before adding and presses and increase and be 120KPa in the vehicle exhaust, constant-speed fuel economy descends 4%, actual fuel consumption per hundred kilometers descends about 10%, and cylinder barrel, bent axle, big or small bearing shell etc. do not have corrosion phenomenon to take place, and oil circuit is clean, do not have deposition, travel 4.8 ten thousand kilometers and do not have wearing and tearing.
