High-density and high-strength carbon graphite material and short-process preparation method thereof
The invention discloses a high-density and high-strength carbon graphite material and a short-process preparation method thereof, the short-process preparation method comprises the following steps: carrying out compression molding on a carbon raw material to obtain a green body, then placing the green body in a closed container for roasting, and finally carrying out graphitization treatment to obtain the high-density and high-strength carbon graphite material, the carbon raw material is green coke powder or mesocarbon microbeads; a carbon raw material which is homogeneous with the green body is mixed in a buried sintering material adopted during roasting. According to the method, the high-density and high-mechanical-strength carbon-graphite material can be prepared in a short process, the carbon-graphite material can be effectively prevented from cracking, and the rate of finished products is increased.
本发明公开了一种高密高强炭石墨材料及其短流程制备方法，该短流程制备方法为：将炭质原料压制成型得到生坯，然后将生坯置于密闭容器中焙烧，最后石墨化处理得到所述高密高强炭石墨材料，所述炭质原料为生焦粉或中间相炭微球；焙烧时采用的埋烧料中混有与生坯同质的炭质原料。本发明能短流程制备得到高密度和高机械强度的炭石墨材料，且能有效防止炭石墨材料开裂，提高成品率。
