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

摘要

FIELD: machine building.;SUBSTANCE: mineral, preliminary crumbled to powder, is introduced into process fluid; produced suspension is treated by ultra-sound at power of emission not less, than 5 kWt and duration not less, than 10 minutes. Further, process fluid is drained, while the residue compound is dispersed in a liquid lubricant material containing a surface active substance forming colloid solution with particles of a mineral. Produced mixture is settled and suspension, formed over sediment, is used as additive to main lubricating material. Natural mineral contains in wt %: serpentine (lizardite and chrisotile) 80-87, chlorite 2-3, magnetite 1-2, amakinite 1-2, calcite 0.5-1, radio-amorphous phase 8.5-12. Water, or alcohol or kerosene are preferably used as process fluid. Lubricant composition contains main lubricating material and compound produced by the above described method.;EFFECT: reduced wear of friction units, reduced losses for friction, increased efficiency of machines and equipment, and reduced consumption of lubricating materials.;5 cl, 1 tbl, 2 dwg
