Carbon graphite material and preparation method thereof
The invention provides a carbon graphite material and a preparation method thereof, and relates to the technical field of carbon graphite materials. The carbon-graphite material is prepared by taking graphite powder, silicon carbide powder, silicon powder, pitch coke and carbon black as main materials, taking modified phenolic resin as an initiator and taking micro hollow carbon spheres as a pore-forming agent, and carrying out gradient roasting after the materials are mixed, immersed and dried. According to the material, a pore-forming agent is set to be a miniature hollow carbon sphere, air is arranged in the miniature hollow carbon sphere, and after the miniature hollow carbon sphere is heated at 1000 DEG C for three hours, internal carbon of the miniature hollow carbon sphere reacts with oxygen in internal gas, so that an inner hole in the miniature hollow carbon sphere is shaped, and a circular inner hole is formed in carbon graphite; the miniature hollow carbon spheres and the carbon graphite are made of the same material, so that the carbon graphite material cannot be changed due to introduction of impurities.
本发明提供一种碳石墨材料及其制备方法，涉及碳石墨材料技术领域。该碳石墨材料，材料以石墨粉、碳化硅粉末、硅粉、沥青焦以及炭黑为主要材料，以改性酚醛树脂引发剂，以微型空心碳球为造孔剂，以上材料经过混合、浸药以及干燥后，进行梯度焙烧而成。该材料将造孔剂设置为微型空心碳球，微型空心碳球的内部设置有空气，微型空心碳球在1000℃加热三个小时后，使得微型空心碳球的内部碳与内部气体中的氧气反应，从而使得微型空心碳球内的内孔定型，从而在碳石墨内部形成圆形内孔，微型空心碳球与碳石墨的材料相同，不会因为引入杂质导致碳石墨材料发生改变。
