The invention relates to a methd for increasing the anti- oxidizing performance of carbon anode for aluminum electrolysis, belonging to aluminum electrolytic industry technique. It comprises following steps: preparing bottom and exterior paint, coating prepared bottom paint on the surface of anode, the thickness is 1- 2mm, coating exterior paint on surface of anode after it is dry, the thickness is 1- 2mm. drying. The organic adhensive is used for coating, there is no foreign matter in raw material and no foreign element in electrolysis process, and the adhesiveness between the first layer and base material can be improved by carbon transition.
