Problems solved by technology

However, the existing polyethylene pipes have low tensile strength and impact strength, and poor wear resistance, so they are not suitable for pipe jacking construction (pipe jacking technology is a non-excavation excavation pipe jacking technology used in municipal construction. , its advantages are that it does not affect the surrounding environment or has little impact, the construction site is small, the noise is low, and it can work deep underground)

Abstract

The invention discloses a polyethylene cable duct. The polyethylene cable duct is characterized by being prepared from a modified polyethylene material; and the modified polyethylene material consists of the following components by weight: 100 parts of base material, 1 to 5 parts of ethylene propylene diene monomer resin, 0.1 to 1 part of polytetrafluoroethylene, 0.1 to 1 part of calcium stearate, 0.1 to 1 part of polyethylene wax and 0.01 to 0.1 part of pigment, wherein the base material consists of 85 to 95 weight percent of high-density polyethylene and 5 to 15 weight percent of ultra-high molecular weight polyethylene. The polyethylene cable duct has the following excellent performance: (1) high tensile strength; (2) high impact strength: the polyethylene cable duct has excellent low-temperature impact resistance and extremely low brittleness temperature and can be safely used at the temperature of between 20 DEG C below zero and 60 DEG C; (3) high abrasion resistance; (4) high toughness, flexibility and shock resistance; (5) high stress cracking resistance and low notch sensitivity; (6) corrosion resistance and long service life; and (7) simplicity in cable threading.

Description

technical field [0001] This invention relates to conduits for laying electrical cables, and in particular to a polyethylene cable conduit. Background technique [0002] Polyethylene pipes (PE pipes) are light in weight, easy to repair, install and maintain, easy to transport, have good stress crack resistance, excellent low temperature impact resistance, and good deflection, rigidity, flexibility, and creep resistance. However, the existing polyethylene pipes have low tensile strength and impact strength, and poor wear resistance, so they are not suitable for pipe jacking construction (pipe jacking technology is a non-excavation excavation pipe jacking technology used in municipal construction. , its advantages are that it does not affect the surrounding environment or has little impact, the construction site is small, the noise is low, and it can work deep underground). Contents of the invention [0003] The technical problem to be solved by the present invention is to p...
