Preparation method of isotropic graphite
The invention discloses a preparation method of isotropic graphite, relates to the technical field of isotropic graphite preparation, and aims to solve the problem that an existing isotropic graphite preparation method needs to be improved. The preparation method comprises the following steps: crushing and shaping raw materials, adding the crushed and shaped raw materials into a kneading machine, adding modified coal pitch, kneading for a period of time at a set temperature, starting to introduce nitrogen into a kneading machine chamber, starting to pressurize, raising the temperature to continue kneading after the pressure reaches a required value, reducing the temperature and relieving the pressure after kneading to obtain a paste block, crushing, adding the paste block into the kneading machine, and carrying out granulation to obtain the modified coal pitch. Adding modified coal pitch, kneading for a period of time at a set temperature, starting to introduce nitrogen into a kneading machine chamber, starting to pressurize, raising the temperature to continue kneading after the pressure reaches a required value, cooling and releasing the pressure after kneading to obtain a paste block, crushing to obtain fine powder, and preparing isotropic graphite through subsequent processes; the steps are simple, reasonable and easy to operate, and the isotropy of the graphite product is excellent.
本发明公开了一种各向同性石墨的制备方法，涉及各向同性石墨制备技术领域，为解决现有各向同性石墨制备方法有待改进的问题；本发明包括将原料破碎整形后加入到混捏机中，再加入改质煤沥青，在设定的温度下混捏一段时间后，开始通氮气进入混捏机室，并开始加压，压力达到所需值后升温继续混捏，混捏完成后降温泄压得到糊料块，破碎后加入到混捏机中，再加入改质煤沥青，在设定的温度下混捏一段时间后，开始通氮气进入混捏机室，并开始加压，压力达到所需值后升温继续混捏，混捏完成后降温泄压得到糊料块，破碎得到细粉，经后续工序制成各向同性石墨；本发明步骤简单合理易操作，石墨产品各向同性度优异。
