A kind of cc composite material prepares the method for graphite paper

Abstract

The invention discloses a method for preparing graphite paper from a CC composite. The method comprises the following steps: step 1, raw material grinding and screening: various raw materials for preparing the graphite paper are poured into a ball mill independently respectively for grinding and then screened, wherein the raw materials comprise the CC composite, graphene powder, graphite powder, carbon black and graphite flakes. The method for preparing the graphite paper from the CC composite has the following beneficial effects: the CC composite, the graphene powder, the graphite powder andother powdery materials are converted into microcrystalline artificial graphite by high-temperature purification treatment at 2500 DEG C at most, so that electrical conductivity, thermal conductivity,self-lubrication and other properties of the graphite paper can be enhanced, and the graphite paper can be widely applied to various electronics and sealing materials; the preparation process is simple, and the prepared graphite paper has stable performance and good electrical conductivity, thermal conductivity and self-lubrication.
