The invention discloses an acidic and environmentally friendly anti-oxidation process for electrolytic copper foil. The steps include: using 2-mercaptobenzoxazole MBO, ethylene glycol, silane coupling agent, alkanolamine and sodium alpha-alkenyl sulfonate with Water is prepared into an anti-oxidation solution; the electrolytic copper foil is introduced into the anti-oxidation solution to soak and adsorb for 5-20s; the soaked and adsorbed electrolytic copper foil is exported and dried before being rolled. The present invention uses 2-mercaptobenzoxazole (MBO), ethylene glycol, silane coupling agent, alkanolamine, sodium α-alkenyl sulfonate as the main components of a novel surface acidic anti-oxidation treatment process to realize lithium battery copper foil Chromium-free anti-oxidation treatment, ensuring that the anti-oxidation performance of the product meets the existing technical standards and reducing copper foil defects and improving the target of yield. The copper foil is not washed with water after the anti-oxidation treatment, thereby reducing the amount of tap water in the copper foil manufacturing process. The manufacturing cost, and at the same time, the surface of the copper foil does not need to be electroplated with other protective metals after the anti-oxidation treatment, and the purity of the copper foil is further improved.
