Preparation method of isostatic pressing negative electrode carbon material
The invention belongs to the technical field of carbon material preparation, and particularly relates to a preparation method of an isostatic pressing negative electrode carbon material, which comprises the following steps: S1, raw material preparation: preparing pitch coke, calcined coke and modified pitch; S2, primary grinding: grinding the calcined coke and pitch coke into powder; S3, dry mixing: adding the ground calcined coke and pitch coke into a mixing and kneading pot for dry mixing; S4, mixing and kneading: after fully melting the asphalt, adding the asphalt into the mixing and kneading pot for mixing and kneading; S5, secondary grinding: grinding the paste mixed and kneaded in the step S4 into powder; S6, vacuumizing and pressing: putting the paste ground in the step S5 into a material bag, conducting vacuumizing treatment, and carrying out isostatic pressing treatment; S7, graphitization: feeding the pressed product into a graphitization furnace for graphitization treatment; and S8, grinding again: grinding the graphite product subjected to graphitization treatment. The method is easy to operate, low in cost and small in labor amount.
本发明属于碳材料制备技术领域，具体涉及一种等静压负极碳材料的制备方法，包括以下步骤：S1、原料准备：准备沥青焦、煅后焦和改质沥青；S2、一次磨粉：将煅后焦和沥青焦进行磨粉；S3、干混：将磨粉后的煅后焦和沥青焦加入混捏锅中进行干混；S4、混捏：沥青充分融化后，加入混捏锅中进行混捏；S5、二次磨粉：将S4混捏后的糊料磨粉；S6、抽真空及压制：将S5磨粉后的糊料装入料包中进行抽真空处理；之后送入等静压进行压制处理；S7、石墨化：将压制处理后的产品送入石墨化炉中进行石墨化处理；S8、再次磨粉：将石墨化处理后的石墨品进行磨粉处理。本发明操作简单、成本低、用工量少。
