The invention provides a submicron copper-based running-in restorative with running-in and restoring functions and reliable effect. The submicron copper-based running-in restorative is prepared by the following steps: taking submicron copper powder as a basic raw material, washing by deionized water, pulping by absolute ethyl alcohol, repeatedly performing vacuum filtration, replacing moisture therein, performing oil solubility treatment, pulping by a base oil (poly-alpha-olefin oils) for synthesizing a lubricant oil after secondary vacuum filtration, adding antioxidant, stirring and curing, wherein the specific gravity range of the slurry is 0.86-0.95, and the addition amount of the antioxidant accounts for 0.5-3.5% of the total volume of the slurry. The restorative in the invention has running-in and restoring functions, reliable effect, extremely strong inoxidizability, has the advantages of nano cooper powder restorative, makes up for the defect of easy oxidation of the nano copper powder, becomes a novel machine running-in restorative, and can be applicable to the machine running-in field, especially for engines of automobiles, steamships, motorbikes and the like. The restorative in the invention adopts the lubricant oil as a dilute dispersion medium, has double functions of running-in and restoring, lowers energy consumption, reducing emission and prolongs service life of engines.
