NOVELTY - Brushed lubricating oil comprises lubricating oil and graphene powder. USE - Brushed lubricating oil for drawing bonding wire. ADVANTAGE - The brushed lubricating oil improves the service life of a stretching die, improves the processing precision and yield, reduces production cost and prevents the bonding wire from oxidation. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a method for preparing brushed lubricating oil, which involves heating a lubricating oil, adding a graphene powder, and ultrasonically to obtain lubricating oil; and (2) a method for drawing bonding wire, which involves covering a wire drawing die with a brushed lubricating oil, and then drawing the wire to obtain a bonding wire, drawing lubricating oil comprising lubricating oil and graphene Powder.
