Summary:The invention relates to the technical field of carbon materials, and discloses a foam carbon material and a preparation method thereof. The method comprises the steps: (1) mixing asphalt, a resin and a heat conduction additive, and carrying out curing treatment on the obtained mixture; and (2) carrying out heat treatment on the product obtained in the step (1) under inert gas to obtain the foam carbon material. According to the invention, asphalt, a resin and a heat conduction additive are mixed and then subjected to curing treatment, then foaming and carbonization are performed at high temperature and normal pressure to obtain the foam carbon material with good heat-conducting property and high compression strength, the method is low in equipment requirement and good in safety performance, foaming and carbonization can be continuously performed, and the technological process is simplified. 本发明涉及炭材料技术领域，公开了一种泡沫炭材料及其制备方法，该方法包括：(1)将沥青与树脂、导热添加剂混合，得到的混合物进行固化处理；(2)在惰性气体下，将步骤(1)得到的产物进行热处理，得到泡沫炭材料。本发明通过将沥青与树脂、导热添加剂
