Preparation method and application of mould pressing graphite sagger
The invention relates to the technical field of sagger production, and particularly discloses a preparation method and application of a mould pressing graphite sagger. The preparation method comprises the following steps: carrying out microwave irradiation modification reaction on crystalline flake graphite by using soluble ferric salt, then uniformly mixing with a macromolecular adhesive to obtain mixed powder, putting the mixed powder in a mold, applying a magnetic field and vibrating at the same time to obtain mixed powder which is neatly arranged in the mold, pressure is applied to the interior of the mold, heating and temperature rise are conducted for preliminary curing after compression molding, and the mold-pressed graphite saggar is obtained after high-temperature carbonization is further conducted. The method can be used for preparing the lithium battery negative electrode material and has the advantages of being good in heat conductivity, not prone to being oxidized, short in processing period and the like.
本申请涉及匣钵生产技术领域，具体公开了一种模压石墨匣钵制备方法及其应用。一种模压石墨匣钵制备方法，包括以下步骤：使用可溶性铁盐对鳞片石墨进行微波辐照改性反应后与高分子粘合剂混合均匀，得到混合粉体，将混合粉体防止在模具中施加磁场同时进行振动，得到在模具内整齐排列的混合粉体，向模具内施加压力，模压成型后加热升温初步固化，进一步进行高温碳化后得到所述模压石墨匣钵。本申请的方法可用于制备锂电池负极材料，其具有导热性好、不易被氧化、加工周期短等优点。
