Obtain settled solution；Above-mentioned settled solution is put in ultrasonic disperser, after ultrasonic disperser processing, obtains nanometer
Diamond aqueous solution；Add editic acid EDTA as organic cooperation base in above-mentioned diamond aqueous solution, concentration reaches
0.015-0.5mol/L.；Precipitate is isolated by centrifugation；Acquirement precipitate is heated under vacuum and is concentrated into powder
Last shape；Repeat the above steps are multiple.Non-nano diamond particles and the impurity of nano diamond particle surface is made persistently to reduce..
The Nano diamond powder obtaining is screened by 2 through centrifuge, and 6000-15000 rev/min of centrifuge revolution obtains
The diamond particles of diameter 20-170 nanometer.Wherein particle diameter 20-80 nanometer accounts for 30%, 80-120 nanometer 50%, 120-170
Nanometer 20%.
3 will be modulated into through 30 minutes ultrasonic disperse in basic for the Nano diamond filtering out addition No. 10 white oils in proportion
The oil additives of the 7-10% of particle containing diamond nano.After oil additives makes an addition to the lubricating oil in machinery equipment, lubrication
Diamond nano particle content in oil is 0.1%.
The Nano diamond that this product is applied, can form free dispersion in oil, have height liquid body and suspend
Stability, Zeta potential is by -40 to -85 millivolts.
The invention has the beneficial effects as follows improve nanodiamond particle suspension stability it is ensured that lubricating oil efficient
Serviceability.The lubrication in all metal friction surfaces can be applied.There is raising friction efficiency, repair friction surface abrasion,
Improve the function of Working Life of Lubricating Oil.
