Preparation method of heat-conducting foam carbon and prepared heat-conducting foam carbon
The invention relates to a preparation method of heat-conducting foam carbon and the prepared heat-conducting foam carbon, and the preparation method comprises the following steps: (1) crushing an asphalt component, carrying out dry mixing on the crushed asphalt component, porous graphite and an optional heat-conducting reinforcing material for uniform mixing, and then carrying out compression molding; (2) treating the preformed material obtained in the step (1) for more than 10 minutes at 450-700 DEG C under normal pressure to obtain a formed material; (3) performing high-temperature treatment on the molded material obtained in the step (2) at normal pressure and in a protective atmosphere at the temperature of 900 DEG C or above to obtain a foam carbon material; a normal-pressure preparation process is adopted, the process is simple and convenient, the cost is low, a low-density porous structure and multi-stage pore size distribution are achieved through effective lap joint between porous graphite, and a larger amount of liquid phase change materials can be better bound.
本发明一种导热泡沫炭的制备方法及制得的导热泡沫炭，所述制备方法包括(1)将沥青组分粉碎后与多孔石墨以及任选地导热增强材料进行干混以混合均匀，然后压制成型；(2)将步骤(1)所得预成型料在常压下于450‑700℃处理10min以上，得到成型材料；(3)将步骤(2)所得的成型材料在常压下且保护气氛中选择900℃以上的温度进行高温处理，以得到泡沫炭材料；本发明采用常压制备工艺，工艺简便成本低，并且利用在多孔石墨之间的有效搭接实现低密度多孔结构，孔径多级分布，可以更好的束缚液态更大量的相变材料的。
