The invention discloses a steel wire frame reinforced polyethylene composite pipe and a preparation method thereof. The composite pipe comprises a core pipe, a steel wire frame reinforced layer and an outer surface layer, wherein the core pipe and the outer surface layer are made of the same material and are prepared from the following raw materials in parts by weight: 160 to 170 parts of polyethylene, 30 to 35 parts of chlorinated polyethylene, 70 to 80 parts of epoxy resin, 7 to 8 parts of dibutyltin dilaurate, 6 to 9 parts of calcium stearate, 8 to 10 parts of polyethylene wax, 6 to 8 parts of jade powder, 5 to 7 parts of barium laurate, 7 to 9 parts of alkyl phosphate, 4 to 8 parts of fluorine grease, 5 to 6 parts of glycidyl methacrylate, 9 to 14 parts of silane coupling agent, 10 to 15 parts of polyethylene glycol terephthalate, 12 to 14 parts of phosphite antioxidant, 10 to 12 parts of nanometer zirconium oxide and 8 to 10 parts of additive master batch. The pipe provided by the invention has higher tensile strength, higher bending strength, high modulus and high impact resistance; the preparation method of the pipe is simple and easy to operate; pipes with different specifications and purposes can be prepared by different dies of the pipes to satisfy social needs.
