The invention relates to the field of conductive bar production, in particular to an anti-oxidation surface treatment method for a conductive bar. The anti-oxidation surface treatment method comprisesthe following steps of 1, soaking the conductive bar to be treated in a cleaning solution to remove oil stains and
rust on the surface of the conductive bar; 2, cleaning the cleaned conductive bar with deionized water, and wiping the conductive bar with a wiping cloth; 3, placing the dried conductive bar in a
solvent containing an
antioxidant, heating the conductive bar to 50-200 DEG C, and carrying out sealed and pressurized reaction; and 4, after the treatment is finished, cleaning and then
drying the conductive bar at a low temperature. By adopting a
chemical agent blending, heating and pressurizing treatment method, the process is simple, little
pollution is caused, and the process is controllable.
