摘要：针对石墨具有天然的憎水性,单纯的石墨颗粒不易在水中分散,必须添加亲水性物质作为分散剂的问题,以羧甲基纤维素钠为分散剂,在相同的工艺条件下制备石墨-水系浆料,研究羧甲基纤维素钠用量及分散时间对鳞片石墨颗粒在水中分散效果的影响。结果表明,羧甲基纤维素钠的质量分数为1%,球磨分散时间为20 min,鳞片石墨颗粒在水中的分散效果最好。

Abstract：Aiming at the natural hydrophobicity and poor dispersion in water of graphite particles,taking carboxymethylcellulose sodium as a dispersing agent,the graphite aqueous slurry was prepared under the same process conditions.The effect of the carboxymethylcellulose sodium dosage and dispersion time on dispersion of flake graphite particles was studied.The results show that the best mass fraction of carboxymethylcellulose sodium is 1%.The best dispersion time is 20 min.
