Aluminum electrolysis anode covering material and preparation method thereof

The invention provides an aluminum electrolysis anode covering material and a preparation method thereof, and belongs to the technical field of aluminum electrolysis, and the aluminum electrolysis anode covering material comprises the following components in percentage by mass: 88-97% of corundum castable; 3%-12% of a castable binder; the aluminum electrolysis anode covering material is an integral covering material. According to the aluminum electrolysis anode covering material, the corundum castable is used as a main material component, and the castable binding agent is used as an auxiliary material component, so that the integral covering material for the aluminum electrolysis anode is obtained, and a series of problems of high labor cost and the like caused by a bulk covering material are effectively avoided; and meanwhile, the corundum castable is used as a main material component of the aluminum electrolysis anode covering material, so that the erosion of electrolyte to the covering material can be effe
