Beschreibung
Zusammenfassung:	The invention discloses a graphene-carbon black composite granule and a preparation method and application thereof. The preparation method mainly comprises the following steps: uniformly dispersing graphene into an aqueous carbon black dispersion, carrying out mixing according to a mass ratio of 1: (1000-2) to form a stable graphene-carbon black composite dispersion, and granulating the graphene-carbon black composite dispersion at 40-80 DEG C. According to the invention, the application problem that graphene is difficult to be uniformly dispersed in a high polymer material is solved; a related process routes are simple; reaction conditions are mild; raw material sources are rich; and safety and environmental protection are achieved. 本发明公开了一种石墨烯分散方法-石墨烯-炭黑复合粒料及其制备方法和应用，涉及一种石墨烯与炭黑的复合粒料、其制备方法和应用。本发明主要是通过将石墨烯均匀分散于炭黑水分散液内按质量比为1∶1000～2比例混合形成稳定石墨烯-炭黑复合分散液，再将所述石墨烯-炭黑复合分散液40～80℃进行造粒。解决石墨烯在高分子材料中难以均匀分散的应用问题。且相关工艺路线简单、反应条件温和、原料来源丰富，安全环保。
