Steel wire frame reinforced polyethylene composite pipe and preparation method thereof

Abstract

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.

Description

Technical field [0001] The invention involves the field of composite pipelines, specifically a steel wire skeleton enhanced polyethylene compound pipe and its preparation process. Background technique [0002] Traditional steel pipelines have poor corrosion resistance and are not easy to move, and they cannot meet the current needs.my country's main oil and natural gas are mostly distributed in deserts, swamps, or mountain areas. The natural environment is relatively harsh. When laid the steel pipeline, it is very serious due to the natural environment. Due to ground sinking and landslide, the transportation pipeline is extremely prone to damage.The composite plastic composite tube of the steel wire mesh is a high -strength over -intensity hypoplash mesh skeleton and thermoplastic plastic polyethylene.High -density polyethylene is closely connected together to make it excellent compound effect.Because of the high -strength steel wire enhanced body is covered in continuous thermop...

[0002] Traditional steel pipes have poor corrosion resistance and are not easy to handle, so they can no longer meet the current needs

my country's main oil and natural gas are mostly distributed in deserts, swamps or mountainous areas, and the natural environment is relatively harsh. The laying of steel pipelines is seriously affected by the natural environment, and due to ground subsidence, landslides and other reasons, the pipelines are extremely prone to damage.
