The invention discloses a preparation method of an isotropic graphite material, which comprises the following steps: after doping mesophase carbon microspheres with different particle sizes and chopped carbon fibers, subjecting them to liquid phase oxidation treatment, and then conducting secondary cold isostatic pressing Method for compression molding, followed by carbonization and graphitization. The invention effectively overcomes the problem of low yield caused by product cracking in the existing ink preparation technology using mesocarbon microspheres as raw materials, and also improves the bending strength of the graphite material, improves the compactness, reduces the resistivity and open porosity, thereby improving the properties of graphite materials. |
