Problems solved by technology

[0002] Due to the characteristics of light weight, corrosion resistance and long service life, polyethylene pipes are widely used in petroleum, chemical, mining, construction and other industries. When used to transport solid particles and powder media, the inner wall of polyethylene pipes is easy to wear , so that polyethylene pipes fail and have a shorter service life

Embodiment Construction

[0015] The present invention will be further described below according to the accompanying drawings and in conjunction with the embodiments.

[0016] The high-performance modified polypropylene and polyethylene composite pipe shown in the accompanying drawings has a three-layer composite structure, with polypropylene layer 1, metal skeleton layer 2, high-density polyethylene, and nanocomposite layer 3 in sequence from outside to inside.

[0017] The metal skeleton layer 2 is a mesh skeleton structure formed by spirally winding high-strength steel wires left and right. In this embodiment, the high-strength steel wires of the metal skeleton layer 2 are high-strength copper-coated steel wires.

[0018] The polypropylene layer 1 is a polypropylene pipe extruded from a modified polypropylene material.

[0019] The high-density polyethylene and nanocomposite layer 3 is compounded by adding nanoparticles to high-density polyethylene, and its thickness is 1.0-2.0 mm. In this embodimen...

Abstract

The invention discloses a modified polypropylene and polyethylene composite pipe with high performance. The modified polypropylene and polyethylene composite pipe with high performance is three-layer structure composed of the polypropylene layer, metal frame layer and high density polyethylene nano-composite layer from the outer part to the inner part; the metal frame layer is the mesh frame structure formed by the high-tensile steel wire wound at the left and right sides in a spiral winding mode; further improvement is as follows, the high-tensile steel wire of the metal frame layer is the high-tensile copper plated steel wire; the thickness of the high density polyethylene nano-composite layer is 1.2 to 2.0 <mm>; the polypropylene layer is the polypropylene tube extruded by the modified polypropylene material; the high density polyethylene nano-composite layer is composed by adding the nano particles in the high density polyethylene. The modified polypropylene and polyethylene composite pipe with high performance is high in abrasion performance, long in service life, excellent in hot melt connection performance for conveniently connecting and mounting the pipeline and guaranteeing the pipe connection airtightness.

Description

technical field [0001] The invention relates to a pipe, in particular to a polyethylene pipe. Background technique [0002] Due to the characteristics of light weight, corrosion resistance and long service life, polyethylene pipes are widely used in petroleum, chemical, mining, construction and other industries. When used to transport solid particles and powder media, the inner wall of polyethylene pipes is easy to wear , making the polyethylene pipe invalid and having a shorter service life. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention proposes a high-performance modified polypropylene and polyethylene composite pipe with good wear resistance and long service life. [0004] The present invention achieves technical goals through the following technical solutions. [0005] The high-performance modified polypropylene and polyethylene composite pipe is improved in that: the high-performance modified polypropylene and polyethy...
