The invention provides a coating material for preventing a carbon anode from being oxidized at high temperature, which comprises the following components: 35-55wt% of inorganic bonding agent, 30-60wt% of composite ceramic filler, 1-10wt% of catalyst, 0-1wt% of sintering agent and 1-10wt% of toughening agent. The coating material disclosed by the invention has good toughness, strong binding force and strong thermal shock resistance, has the characteristics of convenience in construction, normal-temperature curing, low-temperature densification, no toxicity, environmental friendliness, durability, effectiveness and the like, can be used for remarkably reducing the high-temperature oxidation burning loss of the carbon anode and prolonging the service life of the anode. |
