Graphene-carbon graphite composite isostatic pressing material and preparation method thereof
The invention relates to a preparation method of a graphene-carbon graphite composite isostatic pressing material, which specifically comprises the following steps: obtaining components meeting index conditions, preparing a precursor A, preparing a precursor B and treating a composite material, and preparing the graphene-carbon graphite composite isostatic pressing material based on the steps. The raw materials are reasonably selected, and the preparation process is scientific; through research and test, the inventor finally determines the components and the proportion of the components, due to the components and the proportion relation of the components, particles with different particle sizes can be tightly stacked, and the volume density, the porosity, the mechanical strength and the thermal expansion coefficient of the material can reach a very good balance; namely, the prepared material is large in volume density, small in porosity, small in thermal expansion coefficient and high in mechanical strength, and the physical and chemical indexes of graphite are excellent.
本发明涉及一种石墨烯‑碳石墨复合等静压材料的制备方法，具体包括以下步骤：获取满足指标条件的各组分‑制备前驱体A‑制备前驱体B‑复合材料的处理，基于上述步骤制成石墨烯‑碳石墨复合等静压材料；本发明原料选择合理，制备工艺科学；发明人人经过研究和试验，最终确定本发明中各组分及其配比，正是由于本发明中的各组分及其配比关系，才会导致不同粒径的颗粒堆积较为紧密，材料的体积密度、气孔率、机械强度和热膨胀系数可达到一个非常好的平衡，也就是所说其所制备材料的体积密度大、气孔率小、热膨胀系数小、机械强度高，石墨的各理化指标优良。
