Abstract
The lubrication repairing agent containing nanometer metal micropowder is made of nanometer metal micropowder, antioxidant and solvent under a certain technological condition by production process. Said nanometer metal micropowder possesses the superfine nanometer micropartictes only containing tens to setens of thousands of atoms, so that these nanometer microparticles are characterized by low melting point and strong agglutinating property, therefore the invented lubrication repairing agent containing nanometer metal micropowder can raise repairing speed, and is convenient for reparation in mechanically-driving and mechanically-matching movement field.
Description
The present invention relates to the material application class, particularly a kind of lubricating repairing agent of nanometer metal micropowder.
As everyone knows, in mechanical transmission, mechanical engagement motion, friction, wearing and tearing often appear at present, because friction and the existence of wearing and tearing, often make machinery behind the work certain hour, must repair or renewal part, otherwise can influence machine work precision and normal operation.As the engine in all kinds of automobiles, after stroke surpasses certain mileage, the cylinder body of engine occurs that burn oil, compression ratio descend, tail gas emits blue smoke, therefore cylinder body is wanted place under repair, boring cylinder or is changed piston, not only takes a lot of work, time-consuming, expensive, also out of service, at this situation, if also once the someone imagines and can make a kind of healant that has the metal molecule and be coated in the cylinder bore, can repair at once and be science, optimal.Yet limit by scientific and technological level and also can not make this metal particle, and the physical property of existing particulate, mechanicalness, coking property all do not reach the requirement of making this healant, this is the developing a kind of shortcoming of material.
Purpose of the present invention is at the shortcoming of above-mentioned existence, a kind of lubricating repairing agent of nanometer metal micropowder is provided, utilize the nano metal particulate little to the super cell pellets that only contains tens to several ten thousand atoms, the physical property that reaches so small nanometer metal micropowder differs very big with the physical property of original metal, fusing point as metallic nickel is 1455 ℃, and the fusing point of nano level pure nickel micro mist just has only 80 ℃, and nanometer metal micropowder as long-pending form macromole after, its performance is recovered original performance again, and this is just for the invention provides supremacy clause.
Technical conceive of the present invention:
According to purpose of the present invention, a kind of lubricating repairing agent of nanometer metal micropowder is provided, its principle is because the manufacturing of nanometer metal micropowder is the once leap of Materials science, nano material is the product that nanoscale science and technology combines with Materials science, nanometer claims millimicron again, be a kind of unit of length, a nanometer equals 10
-9Rice, nanosecond science and technology are science and technology of in 0.1～100 nanometer range material and life being studied and being used, nanosecond science and technology have made the mankind directly utilize atom and molecule to produce at present, can produce super cell pellets---the nanoparticle that only contains tens to several ten thousand atoms, and with it as the basic comprising unit, be arranged in the nano-solid material, nano material mainly includes the nanoparticle of metal, metallic compound, inorganics, polymkeric substance at present, forms the unconventional solid material with property through mixing compacting, sintering or sputter.The characteristic that the present invention utilizes nanometer metal micropowder to have, the one, the geometrical dimension of nanometer metal micropowder is small, be actually the cluster of tens to several ten thousand atoms, this moment nanometer metal micropowder physical property and the physical property of original metal to compare difference especially big, fusing point as metallic nickel is 1455 ℃, and the fusing point of nanometer metal micropowder has only 80 ℃, and for example the fusing point of Yin nano powder only is 100 ℃, the plastic creep temperature of nanometer nickel micro mist also has only 78 ℃, and after the nanometer metal micropowder melting and reducing became the large size metal, physical properties such as its fusing point were recovered the performance of original metallic substance again.Therefore, when move mutually in the metal parts surface,, entered metal parts surface certain depth because the size of nanometer metal micropowder is small, form the metallic cementation film, slightly larger nanometer metal micropowder particle is under the effect of friction, because the friction local temperature raises, nanometer metal micropowder forms plastomer, fill and lead up the small recess of friction surface, scar, make the friction surface of part obtain repairing, Here it is rationale of the present invention.
Advantage of the present invention:
1, manufacture technology of the present invention is simple, less investment, instant effect.
2, the present invention repairs that part is convenient, to recover the original form size fast, and wear resistance and that hardness ratio is original is taller before repairing, because the nanometer metal micropowder that uses is with the high nanometer metal micropowder of wear resistance.
3, use healant of the present invention, can save a large amount of repairing expense,, carry out the boring cylinder or change cylinder sleeve and piston as pulling of former repairing cylinder body, not only waste material takes, working hour expense, also to delay automobile and haul goods the time, if with repairing lubricant of the present invention, as long as in the lubricant injection cylinder body with 0.1 liter nanometer metal micropowder, engine idle can find that blue smoke obviously reduced in the tail gas in 20 minutes, if behind the normal operation 100KM, prosperous blue smoke disappears substantially, noise also obviously reduces.
4, the present invention not only has mending function, and has the maintenance effect.
Particular content of the present invention:
