Abstract

The invention discloses a preparation method of a graphene material. The preparation method comprises the following steps: S1: preparing electrolysed water: preparing an electrolysed water solution according to the mass ratio 1: 5 of sulfuric acid to water and pumping the electrolysed water solution into a reaction tank; S2: preparing a raw material: preparing a graphitized isostatic product and connecting a wire to the isostatic product; S3: throwing in graphite: throwing the isostatic product that is connected with a wire in S2 into the reaction tank that contains the electrolysed water solution in S1, and guaranteeing the mass ratio 2: 3 of the isostatic product to the electrolysed water solution during throwing; and S4: performing preliminary electrification: electrifying the isostaticproduct thrown in S3, and guaranteeing that the electrifying voltage of the isostatic product is 10 V and the electrifying current thereof is 60 A in the electrifying process. The preparation methodis reasonable in design and utilizes a baking process to prepare graphene; a reaction condition of graphene is easy to meet and control; a reaction process is simple; convenience is brought for a worker to operate; and the product yield is high.

Description

technical field [0001] The invention relates to the technical field of graphene preparation, in particular to a method for preparing a graphene material. Background technique [0002] Isostatic graphite is a new type of graphite material developed in the 1940s, which has a series of excellent properties. Isostatic graphite has good heat resistance. In an inert atmosphere, as the temperature rises, its mechanical strength increases instead. Compared with ordinary graphite, it has a fine and dense structure and good uniformity; its thermal expansion coefficient is very low, and it has Excellent thermal shock resistance. After retrieval, the patent document with application publication number CN103553033A discloses a preparation method of graphene material, which mainly includes oxidative intercalation of raw graphite, ultrasonic exfoliation to obtain graphene oxide, and reduction reaction to generate graphite. Graphene, ultrasonic-assisted separation and preparation of graphe...
