The invention relates to the field of polyethylene electric melting pipeline materials, in particular to modified graphene for polyethylene electric melting pipe fittings or pipes as well as a preparation method and application of the modified graphene. The preparation method of the modified graphene comprises the following steps: taking graphene oxide and 2-bromoisobutyryl bromide as reaction raw materials, and carrying out substitution reaction to obtain brominated graphene; the preparation method comprises the following steps: by taking ethylene and 3-butene-1-amine as grafting monomers, carrying out ATRP (Atom Transfer Radical Polymerization) reaction on brominated graphene to obtain aminated polyethylene modified graphene; taking the aminated polyethylene modified graphene and 2-bromoisobutyryl bromide as reaction raw materials, and carrying out substitution reaction to obtain brominated polyethylene modified graphene; ethylene is taken as a grafting monomer, ATRP reaction is carried out on the brominate
