▎ 摘　　要

NOVELTY - A graphene raw material comprises feed mixture comprising 20-50 %mass graphite, 0.1-2 %mass sodium carboxymethyl cellulose, 0.1-1 %mass Tween (RTM: polysorbate), 2-5 %mass aqueous ammonia, 0.3-3 %mass sodium Methylenebisnaphthalene sulfonate and 0.5-10 %mass gum arabic, and remainder of water. USE - Raw material is used for preparing graphene. ADVANTAGE - The graphene raw material has uniform and fine particle size, and is prepared with high yield and output rate of more than 50%, by economical method. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene raw material, which involves mixing graphite, sodium carboxymethyl cellulose, Tween (RTM: polysorbate), aqueous ammonia, sodium methylenebisnaphthalene sulfonate and gum arabic with water, agitating, stirring, obtaining raw material mixture, milling using bead-mill, adding water, adjusting solid content to 4-6 %mass, centrifuging, collecting raw material mixture having particle size of 1 mu m or less, obtaining liquid microparticles, adding condensing agent, adjusting pH to 2.3-2.8, and filtering.
