METHOD OF PRODUCTION OF NANO-DISPERSED WEAR RESISTANT COMPOUND (NDWRC) AND LUBRICATING COMPOSITION CONTAINING IT

摘要

1. A process for preparing nanosized antiwear composition (SDSS), comprising placing between the rubbing surfaces of the parts a lubricant composition comprising a lubricant and the main SDSS, wherein SDSS is a suspension of a liquid lubricant and a finely divided mineral slurry, the slurry obtained as follows: - a set of natural minerals previously milled to a powder, the magnetic separation is carried out it is introduced into the liquid lubricant disintegrated to a particle size minerals, no more than 1 micron, the resulting mixture is settled, and the resulting sludge suspension is used above as an additive to the lubricant, wherein a set of natural minerals has following component ratio, wt.%: Serpentine (lizardite and chrysotile) 80-87 Magnetite Chlorite 2-3 1-2 1-2 Amakinit Calcite 0.5-1 The amorphous phase 8,5-12,! And immediately before disintegration in the liquid lubricant introduced surfactants, forming particles of minerals in the process of dispersing the colloidal solution, characterized in that, before the disintegration of the liquid lubricant powder is placed in the process fluid and conduct processing the resulting slurry of powder and the process fluid by means of ultrasound at a radiation power e less than 5 kW at a duration of at least 10 minutes, and then produce the process fluid removal, followed by dispersing in a liquid lubricant. ! 2. Method according to claim 1, characterized in that the process fluid is water. ! 3. A method according to claim 1 or 2, wherein m
