Abstract

The invention discloses an anti-wear nanometer copper lubricating oil. The anti-wear nanometer copper lubricating oil is prepared by a method with the following steps of 1, adding a nonionic surfactant into a suspension liquid of nanometer copper anhydrous ethanol, and stirring, so as to obtain a mixed solution A; 2, adding the mixed solution A into basic lubricating oil, treating by ultrasonic waves, centrifuging, and removing precipitate, so as to obtain a mixed solution B; 3, relieving the pressure of the mixed solution B, and distilling, so as to obtain the nanometer copper lubricating oil. The nanometer copper lubricating oil has the advantages that the nanometer copper is uniformly dispersed into the basic lubricating oil under the action of intersolubility between the suspension liquid of nanometer copper anhydrous ethanol and the basic lubricating oil, and the surface tension of the basic lubricating oil is reduced by the nonionic surfactant, so as to block the agglomeration ofnanometer copper particles, and improve the suspension stability of the nanometer copper; while the good lubricating property of the nanometer copper lubricating oil is guaranteed, the anti-wear property of the nanometer copper lubricating oil is greatly improved, the mechanical wear is further repaired, the surface friction coefficient is reduced, and the service cycle of the nanometer copper lubricating oil is extended.

Description

technical field [0001] The invention belongs to the technical field of lubricating oil, in particular to an anti-wear nanometer copper lubricating oil. Background technique [0002] With the development of nanomaterials and the continuous deepening of their application research, nano-copper has better catalytic properties than conventional materials due to its small size effect, surface effect, quantum size effect and macroscopic quantum tunneling effect, and has low shear force. , good thermal conductivity, good ductility, excellent anti-wear and anti-friction performance, people have applied it to the fields of tribology and lubricating oil. However, the surface activity of nano-copper particles is too large, and it is easy to agglomerate, and it is difficult to maintain a stable and uniform suspension state when added to lubricating oil, thereby affecting the anti-wear effect of lubricating oil.
