High-temperature-oxidation-resistant composite material, preparation method thereof and anode for aluminum electrolysis
The invention provides a high-temperature-oxidation-resistant composite material. The high-temperature-oxidation-resistant composite material is prepared from phosphoric acid, boric acid, water, a component capable of reacting with phosphoric acid to generate aluminum dihydrogen phosphate and one or two of chromium aluminum phosphate and a composition capable of reacting to generate chromium aluminum phosphate. The invention further provides the high-temperature oxidation resistant composite material. The invention further provides an anode for aluminum electrolysis. The anode comprises a carbon material and the high-temperature-oxidation-resistant composite material coated on the surface of the carbon material. The high-temperature-oxidation-resistant composite material provided by the invention is a thermosetting water-based coating, has a compact, hard and high-temperature-resistant surface layer after being coated on the surface of a carbon material, isolates the contact between the surface of the carbon material and air and carbon dioxide in an electrolytic bath, reduces the surface oxidation of a carbon anode, and prolongs the service life of the anode.
本发明提供了一种抗高温氧化复合材料，由以下原料制备得到：磷酸、硼酸、水、可与磷酸反应生成磷酸二氢铝的组分以及磷酸铬铝和反应可生成磷酸铬铝的组合物中的一种或两种。本申请还提供了一种抗高温氧化复合材料。本申请还提供了一种铝电解的阳极，包括碳材料和涂覆于所述碳材料表面的上述抗高温氧化复合材料。本申请提供的抗高温氧化复合材料是一种热固性、水性涂料，涂覆于碳材料表面具有表层致密、坚硬、耐高温、隔离了碳材料表面与空气、电解槽内二氧化碳的接触，减少了碳阳极表面氧化，延长了阳极使用周期。
