Preparation method of antioxidant graphite material matrix
The invention discloses a preparation method of an antioxidant graphite material matrix, and belongs to the technical field of inorganic nonmetal graphite sealing materials. The problems that an existing graphite sealing ring is complex in preparation process and low in oxidation resistance are solved. The graphite material matrix is prepared by taking graphitized carbon black as a main raw material and superfine petroleum coke powder and boric acid as auxiliary materials, two-stage production is adopted, the oxidation resistance of the graphite matrix is greatly improved, isostatic pressing is adopted to improve the material micro-structure and reduce oxidation factors, and the obtained graphite matrix has the advantages of high volume density, high graphitization degree and high oxidation resistance.
本发明公开了一种抗氧化石墨材料基体的制备方法，属于无机非金属石墨密封材料技术领域。本发明解决了现有石墨密封环制备工艺复杂且抗氧化性能不高的问题。本发明以石墨化炭黑作为主要原材料，以超细石油焦粉和硼酸为辅料制备，采用两阶段生产，大幅度提升石墨基体抗氧化性，并且采用等静压成型改善材料微观结构，降低氧化因子，获得的石墨基体具有高体积密度，高石墨化度和高的抗氧化性能。
