The invention relates to a preparation method of a mineral graphene reinforced ultra-high molecular weight polyethylene double-resistant pipe. The pipe is prepared from the following raw materials: 100 parts of ultra-high molecular weight polyethylene, 2-5 parts of nano-graphene sheets, 5-10 parts of a coupling agent, 0.1-1 part of a foaming agent, 0.1-1 part of a compatibilizer, 1-2 parts of a lubricating agent, 6-10 parts of a halogen-free flame retardant, 3-6 parts of an antistatic agent, 2-4 parts of a flow modifier, 1-3 parts of a nucleating agent, and the like; the graphene reinforced ultra-high molecular weight polyethylene double-resistant pipe is prepared by the processes of extruding, sizing, and the like. According to the preparation method, nano-graphene, the antistatic agent and the flame retardant are dispersed into ultra-high molecular weight polyethylene resin medium gaps by means of the coupling agent, the compatibilizer, the flow modifier, the lubricating agent, the nucleating agent, and the like; the nano-graphene sheets have significant synergistic flame retardation after being compounded with the flame retardant, and can reduce the resistivity of the pipe after being compounded with the antistatic agent. The prepared pipe has the characteristics of being light in weight, high in strength, flame-retardant, antistatic, and the like, thus being used in the operating environments such as coal mines, downhole and mines in which a great deal of gas exists.
