Electrolytic aluminum prebaked carbon anode ceramic-based high-temperature oxidation-resistant coating and preparation method thereof
The invention discloses an electrolytic aluminum prebaked carbon anode ceramic-based high-temperature oxidation-resistant coating. The surface of a prebaked carbon anode is coated with the coating, then low temperature sintering is performed to achieve densification and capillary pore constriction in order to form a protection isolation layer which is good in adhesiveness with the prebaked carbonanode, complete, compact and high in strength, the protection isolation layer can tolerate the high temperature of 800 DEG C or above for a long time, and contact between the prebaked carbon anode andair and contact between the side face of the carbon anode and CO2 are effectively isolated, so the service life of the carbon anode is prolonged, and 30% of carbon slag falling is reduced.
本发明制备一种电解铝预焙碳素阳极陶瓷基高温抗氧化涂料，涂覆在预焙碳素阳极表面，低温烧结致密，毛细孔收缩，形成一个与预焙碳素阳极附着性好的、完整致密、高强度的保护隔绝层，长期耐受800℃以上高温，起到有效隔绝预焙碳素阳极与空气的接触、碳素阳极侧面与CO的接触，从而延长碳素阳极的使用寿命，并降低30％的碳渣掉落。
