Preparation method of high-strength fine-particle isostatic pressing graphite material

The invention provides a preparation technology of high-strength fine-particle isostatic-pressed graphite, which comprises the following steps: preparing raw material powder with stable particle size by using coke as a raw material, optimizing the powder to obtain raw material powder with specific particle distribution characteristic and average particle size of 10-13 mu m, proportioning, kneading, secondarily grinding and profiling to obtain a green body, and sintering to obtain the high-strength fine-particle isostatic-pressed graphite. And then carrying out roasting, dipping and graphitization treatment to obtain the isotropic high-performance fine-particle isostatic pressing graphite. 本发明提供一种高强度细颗粒等静压石墨的制备技术，使用焦炭作为原材料，制备粒度稳定的原料粉并对粉体进行优化处理后得到具有特定颗粒分布特性且平均粒度为10～13μm的原料粉，并进行配料、混捏、二次磨粉和压型得到生坯，然后经焙烧、浸渍和石墨化处理后，得到各向同性的高性能细颗粒等静压石墨。
