Problems solved by technology

[0003] From the perspective of conductive mechanism, conductive polymers can be roughly divided into two categories. The first category is composite conductive polymers, which refer to polymers as the matrix and various conductive fillers (such as metal powder, conductive carbon black, Graphite, etc.) are materials with certain conductivity obtained by compound methods such as blending and lamination; however, most of these methods must be carried out under high temperature and high pressure, which requires high equipment and high energy consumption

Abstract

The invention discloses a conductive graphene material, which is formed by the following raw materials by weight part: 0.5 to 1 of sorbitan monooleate, 2 to 3 of stearic acid, 10 to 13 of amino carbonblack, 100 to 116 of graphene, 10 to 20 of potassium permanganate, 1 to 2 of ammonium polyphosphate and 2 to 3 of polyamide wax micro powder. Through reaction between amine and stearic acid, the combination strength between the graphene and the carbon black is thus improved, and besides, as the polyamide wax micro powder is introduced, the bonding strength can be improved, the mechanical stability of a finished product material is thus enhanced, and the material has good conductive stability, the weight is light, and the quality is high.
