Regenerated graphite block and preparation method thereof
The invention provides a regenerated graphite block and a preparation method thereof, and belongs to the field of graphite block manufacturing. The preparation method of the regenerated graphite block comprises the following steps that graphite powder generated in the machining process of the graphite block is provided, the graphite powder, carbon fibers and silicon-containing substances are sequentially mixed, pressed into blocks and sintered, and the regenerated graphite block is obtained.By means of the preparation method, a large amount of high-purity graphite powder generated in the machining process can be effectively utilized, and meanwhile the production cost is reduced. And the prepared graphite block has higher heat conductivity coefficient, higher compression and bending strength, smaller thermal expansion coefficient and ultralow preparation cost compared with the original stone block.
本申请提供一种再生石墨块及其制备方法，属于石墨块制造领域。再生石墨块的制备方法包括以下步骤：提供石墨块在加工过程中产生的石墨粉，将石墨粉、碳纤维和含硅物质依次进行混合、压块和烧结，得到再生石墨块，通过该制备方法，能够使得加工过程中产生的大量高纯石墨粉得到有效利用，同时，还能使得制备得到的石墨块具有比原生石块更高的导热系数、更高的抗压抗弯强度和更小的热膨胀系数以及超低的制备成本。
