NOVELTY - Antistatic polyethylene composition comprises polyethylene base resin and edge-modified grapheme, where edge-modified graphene has an average sheet diameter of 2-30 mum, an average aspect ratio of 600-10000:1 and an electrical conductivity of 200-800 S/m and in the edge-modified graphene, the oxygen content in terms of oxygen element is 3-30 at.%, and the hydrogen content in terms of hydrogen element is 1-10 at.%. USE - Used as antistatic polyethylene composition. ADVANTAGE - The polyethylene forming body has strong environmental stress crack resistance, light weight and excellent antistatic performance, and can effectively solve the hollow large container, children entertainment facility, static problem of physical exercise machine. The edge modified graphite preparation method is capable of large preparation high quality of edge carboxylated graphene. The method is environment-friendly, low production cost, short reaction period, simple technique, and the sheet integrity of the edge modified graphene obtained by preparation is good. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) polyethylene molded body prepared from the antistatic polyethylene composition; and (2) preparing polyethylene molding comprising (i) carrying out the first rotational molding of the third polyethylene composition to form the surface layer;(ii) introducing the second polyethylene composition to carry out the second rotational molding and completing the foaming, and forming the intermediate layer in the surface layer; and(iii) introducing first polyethylene composition to carry out the third rotational molding, and the inner layer is formed in the intermediate layer.
