Carbon graphite material and preparation method thereof
The invention discloses a carbon graphite material with a communication hole structure. The preparation method of the carbon graphite material comprises the following steps: putting pitch coke, artificial graphite powder and carbon black into a kneading machine, carrying out dry mixing and then hot mixing, then adding the molten modified pitch, carrying out wet mixing, drying, crushing and screening the wet-mixed paste, uniformly mixing the screened powder with the asphalt-based pre-oxidized fibers, and then molding and roasting to obtain the carbon graphite material with the communicating pore structure. The carbon graphite material provided by the invention has a communicating pore structure, can realize densification of a homogeneous material, can realize smooth introduction of a functional material, improves the comprehensive mechanical properties of the material, reduces brittle failure of the material, and realizes structural and functional integration. The carbon graphite material with the communication hole structure can be applied to the fields of aerospace, transportation chemical industry, mechanical energy and the like.
本发明公开了一种碳石墨材料，具有联通孔结构。该碳石墨材料的制备方法为：将沥青焦、人造石墨粉、炭黑放入混捏机中先进行干混再热混，然后加入熔融状改质沥青进行湿混；再将湿混后的糊料烘干、破碎、筛分，筛分后的粉料与沥青基预氧丝均匀混合，随后进行成型、焙烧，得到具有联通孔结构的碳石墨材料。本发明碳石墨材料具有联通孔结构，可实现同质材料增密，可实现功能材料顺利引入，提高材料的综合力学性能，减少材料脆断，实现结构上的结构‑功能一体化；该联通孔结构的碳石墨材料可应用在航天航空、交通化工、机械能源等领域。
