Abstract

The invention discloses a modified polypropylene corrugated pipe, relating to a conduit for paving cables. The modified polypropylene corrugated pipe is prepared from a modified polypropylene material which consists of the following components in parts by weight: 100 parts of base material, 0.1-1 part of polytetrafluoroethylene, 0.1-1 part of calcium stearate, 0.2-1 part of antioxidant and 0.01-0.1 part of pigment, wherein the base material consists of 65-80% of polypropylene, 5-10% of ethylene propylene diene monomer and 15-25% of microcapsule red phosphorus master batch. A manufacturing method of the modified polypropylene corrugated pipe comprises the following steps of: preparing the modified polypropylene material; and manufacturing the modified polypropylene corrugated pipe. The modified polypropylene corrugated pipe disclosed by the invention has the advantages of good flame retardance, excellent electrical insulation property, good impact resistance, higher heat distortion temperature, good low-temperature impact resistance, light weight, smooth surface and low friction resistance in cable threading, and can be abut-jointed through thermofussion welding, thus the modified polypropylene corrugated pipe is suitable for underground pavement of pipelines and cables and is widely applied to the projects of telecommunication, electric power and the like.

Description

technical field [0001] The invention relates to a conduit for laying cables, more particularly to a modified polypropylene corrugated pipe and a manufacturing method thereof. Background technique [0002] Polypropylene pipe is a kind of green building material, which has the advantages of sanitation, non-toxicity, light weight, corrosion resistance, no scaling, heat preservation and energy saving and long service life; especially after the emergence of homogeneous hot melt connection technology, the installation of pipeline system , A major breakthrough has been made in the connection method, and a safe and reliable integrated pipeline can be constructed. However, polypropylene pipes have poor flame retardancy and low-temperature impact resistance, which limit their application and are not suitable for manufacturing corrugated pipes. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to provide a modified polypropylene corruga...
