摘要
利用水溶性的磷酸二氢铝、磷酸二氢镁、硼酸及六偏磷酸钠等制备抗氧化浸渍剂水溶液,对石墨材料进行浸渍处理,并对该磷酸系列抗氧化剂的抗氧化效果进行了评价。结果显示,经过水溶性抗氧化剂处理后石墨材料的起始氧化温度从400℃提高到500℃,并且在1 000℃依旧能有效防护石墨材料。
The paper evaluates the effects of phosphorylation series antioxidants through the post-impregnation of graphite materials treated with soluble antioxidative impregnants made from water-soluble Al（H2PO4）3, Mg（H2PO4）2, boric acid and sodium hexametaphos- phate. It is shown that the initial oxidation temperature of graphite materials dealt with the water-soluble impregnant rise from 400 ℃to 500 ℃, and the graphite materials are still effectively protected from oxidation at 1 000℃.
