Description
Technical field
The present invention relates to the additive in piston engine lubricating oil field, particularly the automatic repair liquid of a kind of piston engine Nano diamond.
Background technology
In recent years, Nano diamond because of its specific surface area large, hardness is high, is used to add in lubricating oil, to form micro-mill in friction pair, polish the convex cutting edge of a knife or a sword of micron in friction pair, eliminate scuffing, avulsion that friction pair produces in operation process, glue together, the phenomenon such as to kill, friction pair contact area is expanded, frictional coefficient is little, form ball shaped nano diamond surface body, and make lubrication become rolling resistance from sliding friction, be more conducive to lubrication.But in order to play above-mentioned effect, how Nano diamond is dispersed in the key for this technical scheme in lubricating oil.
As Chinese patent CN102925257B discloses a kind of Nano diamond anti-attrition synergistic agent for lubricating oil product and preparation method thereof, comprise the component of following parts by weight, Nano diamond, animal badger fat, coupling agent, tensio-active agent, one line lubricant base, lubricating oil dispersant T155, oxidation inhibitor T501, rust-preventive agent benzotriazole.Formula is complicated, and cost is high, and facts have proved through applicant, after placement for some time, also there will be the agglomeration of Nano diamond.
Chinese patent application 01131537.7 discloses a kind of dispersing technology of Nano diamond, Nano diamond is mixed according to certain weight ratio with lubricating oil, leave standstill for some time, add dispersion agent again, leave standstill for some time, then disperse by ultrasonic wave, and then wetting, make the solid-liquid mixture disperseed meet the requirements of ratio 0.05-2%.Preserve, sampling Detection is carried out according to one hour, 1 day, 1 month, if find significantly precipitation or reaggregation, kind and the proportioning of dispersion agent should be adjusted, that is, according to such dispersing technology, leaving standstill 1 hour, 1 day or after one month, the phenomenon that still there will be precipitation or reunite, needed the kind and the proportioning that adjust dispersion agent.
Summary of the invention
It is good that technical problem to be solved by this invention is to provide a kind of dispersion effect, fills a prescription simply, there will not be the automatic repair liquid of the Nano diamond for piston engine of the phenomenon of secondary agglomeration.
The object of the present invention is achieved like this: the automatic repair liquid of a kind of Nano diamond for piston engine, is characterized in that: comprise following preparation process:
(1), in dispersion agent OP-10 add Nano diamond, stir more than 20min, then leave standstill, after bubble completely dissolve, there is black precipitate in bottom, pours out supernatant liquor; Wherein Nano diamond is spheroidal particle, and its particle diameter is 2-4nm, and the adding proportion of described OP-10 and Nano diamond is add Nano diamond 0.8-1.2mg in every 1LOP-10.
(2), add in lubricating oil by above-mentioned supernatant liquor, be uniformly mixed and obtain automatic repair liquid, the mass percent of wherein said supernatant liquor and lubricating oil is 10%-30%:90%-70%.
Adopt technique scheme, through a large amount of screening of applicant, filter out dispersion agent op-10 as dispersion agent, and by the dissemination of op-10, Nano diamond is purified further and (after leaving standstill, has black precipitate, we only get supernatant liquor, remove black precipitate), remove impurity, again through emulsification of lubricating oils, obtain the automatic repair liquid of high density, wherein containing a large amount of Nano diamond spheroidal particle, the density of density and lubricating oil is close, automatic repair liquid of the present invention is observed under an atomic force microscope, obtain electron microscopic picture as shown in Figure 1, for fenestral fabric, Nano diamond dispersion is embedded in this fenestral fabric, prevent the secondary agglomeration phenomenon under the pedesis in the solution of Nano diamond solid particulate and action of gravity, dispersion effect is good, long-term placement, product is stablized.The present invention forbids with the lubricating oil containing anti-wear agent composition used in combination, best with GB11121-1995 petrol engine oil effect used in combination.
In technique scheme: described Nano diamond is that explosion method obtains, the ash content after purifying, its purity is higher, reaches about 90%, epigranular, is the spheroidal particle of 2-4nm.Beneficial effect: tool of the present invention has the following advantages:
(1) the Nano diamond dispersion effect, in automatic repair liquid of the present invention is good, and good stability, can place for a long time, and formula is simple, cost is low, and preparation method is simple.
(2) after, adding the present invention in lubricating oil, for in piston engine, Nano diamond plays and form micro-mill in friction pair in the moving process of engine, polish the effect in the face, uneven micron peak of the original formation of friction pair, eliminate scuffing, avulsion that friction pair produces in operation process, glue together, the phenomenon such as to kill, friction pair contact area is expanded, frictional coefficient reduces greatly, form ball shaped nano diamond surface body, and make the surface of friction of friction pair become rolling resistance from sliding friction.
(3), automatic repair liquid of the present invention is added in lubricating oil, play automatic effect of repairing engine, long-term use continuously, work-ing life 3-5 times of engine can be extended; Saving fuel oil (combustion gas) 10-18%; Power increases 10-20%; Reduce coolant water temperature 10-20 degree.
(4), be added with after lubricating oil of the present invention uses for some time in motor car engine, according to engine behaviour in service greatly about 400-6000 km, idling improves 10-25% to have the car of tachometer gage to find, user idling please be adjusted to prescribed value, in the clean situation of vaporizer, the effect that fuel-economizing and power increase just clearly.
