Summary of the invention
The present invention provides a kind of lubricated ultrafine nanometer iron powder for the problem that solves the copper powder poor effect of using in the lubricant that exists in the prior art.
The present invention is realized by following technical scheme, a kind of lubricated ultrafine nanometer iron powder, be to make by following method, temperature is controlled under-5 ℃--20 ℃ the prerequisite, then ferrous powder granules is carried out high-speed cutting, high frequency cutting number of times is set under the situation of per minute 5500 times-6000 times and produces nanometer iron powder, high frequency to 4000～6000 rev/mins of the ferrous powder granules after the cutting grinds then, sub-elect the ferrous powder granules that is shaped as global shape between the D50=35nm-60nm, and will carry out polishing to the ferrous powder granules surface with polishing technology.
On the such scheme basis, a kind of lubricated ultrafine nanometer iron powder, be to make by following method, temperature is controlled under-10 ℃--20 ℃ the prerequisite, then ferrous powder granules is carried out high-speed cutting, high frequency cutting number of times is set under the situation of per minute 5700 times-5900 times and produces nanometer iron powder, high frequency to 4500～5500 rev/mins of the ferrous powder granules after the cutting grinds then, sub-elect the ferrous powder granules that is shaped as global shape between the D50=35nm-60nm, and will carry out polishing to the ferrous powder granules surface with polishing technology.
Other product of this level in plain oil suspension time when 30H more than, rate of deposition is not more than 3%.(U.S.'s product 12 hours, rate of deposition is not more than 7%).Form the extraordinary powder that adds of super lubricant.
Nanometer iron powder is activated under the effect of high temperature and high pressure; and firmly ooze and be embedded in metal surface indenture and the micropore; repair perished surface; form the nanometer iron powder diaphragm; because the buffer action of this tunic; make the friction that relative motion produces between parts just act on this layer diaphragm; the nanometer iron powder particle makes friction become rolling friction by traditional sliding friction; thereby reduce frictional force greatly; near-zero is reduced in friction between moving parts, engine is played superpower wear-resistant protective effect, lubricated by improving; can reduce coefficient of friction more than 70%; improve abrasion-resistance more than 300%, reduce wearing and tearing more than 80%, but the prolonged mechanical part life is more than 3 times; addition only is 5/10000ths to one thousandth, and what ratio nano oxide and bronze powder automobile oil result of use will be good is many.
D, the technology of the present invention advantage
In the ordinary people, think iron powder is joined the effect that may play the aggravation friction in the lubricating oil, thus damage or damage plant equipment.In fact, strengthening key point lubricated or the aggravation friction is the granularity and the shape of iron powder.Nanoscale (nm) is evenly spherical, surface finish, and the practical effect of finely dispersed iron powder in lubricating oil is than good many of bronze powder, and its advantage is as follows:
1, the compatibility of nanometer iron powder and present internal combustion engine or friction mechanism is very good.
2, the spherical nano iron powder of producing, processing with the physics method is handled through surface finish, and its mechanical strength is very high, is 2.6 times of bronze powder.
3, the ball shaped nano uniform particles iron powder of handling through surface finish, the suspendability in lubricating oil is highly stable, thereby is evenly distributed, and anti-wear effect is fairly obvious, is bronze powder and other material 5.1 times.My company and research in nanotechnology institute of the Korea S academy of sciences success of co-production " nanometer iron powder antiwear additive ", list marketing at present.
4, the ball shaped nano uniform particles iron powder of surface finish processing; under the pressure and high-temperature condition of mechanical friction; can be higher than the protective layer of mechanical friction face in the surperficial produced by insert molding mechanical strength of mechanical friction face, thus played alleviate mechanical friction, reduce mechanical wear, remedy original mechanical wear, the effect in prolonged mechanical life-span.
5, with the automobile engine be example, the U.S. with the bronze powder be " super lubricant " of additive effectively to use mileage be 10000 kilometers, lubricant effect is 2.2 times of plain oil, hundred kilometers rates of economizing gasoline are 5%.So the ball shaped nano uniform particles iron powder that my company and the research in nanotechnology surface finish of the Korea S academy of sciences are handled is that effective use mileage of " the nanometer iron powder antiwear additive " of additive is 130000 kilometers, lubricant effect is 5.1 times of plain oil, and hundred kilometers rates of economizing gasoline are 13%.
6, same, with the automobile engine is example, 150,000 kilometers of automobile normal runnings---in the time of 200,000 kilometers, the wearing and tearing that cause owing to the long-time friction of motor cylinder block and piston, cause cylinder body and piston clearance to become big, exceed the technical stipulation requirement, thereby cause that automobile power descends, fuel oil increases, climbing is unable, the appearance of problems such as lubricating oil burning.If adding this moment such as U.S. etc. and with the bronze powder be " super lubricant " of additive, effectively to use mileage be 4000 kilometers, automobile power increases to some extent, lubricating oil suspends burning, DeGrain, and also per 4000 kilometers needs add once, after adding 3 times continuously, there is not any effect substantially.If " nanometer iron powder antiwear additive " effectively uses mileage is 40000---80000 kilometers, automobile power can return to original 97%, distinguish not obviously with new car under climbing and the heavily loaded situation, fuel oil slightly increases (2%---3%) than new car, and the lubricating oil combustion problem thoroughly solves.
