Abstract

The invention discloses a flame-retardant high-weatherability high-strength electric threading pipe. The threading pipe comprises the following raw materials by weight: 55-65 parts of chlorinated polyvinyl chloride resin, 24-28 parts of styrenic thermoplastic elastomer, 1-3 parts of a lubricant, 10-14 parts of a compound flame retardant, 4-6 parts of a coupling agent, 3-5 parts of a compound barium-zinc stabilizer, 8-10 parts of an anti-cracking fibers, 2-4 parts of a compound insecticidal and antibacterial agent, 6 -8 parts of a filler, 7-11 parts of a processing aids and 12-16 parts of methyl methacrylate. The threading pipe provided by the invention has the advantages of excellent indexes of tear strength, tensile strength and elongation at breakage, good resistance to aging, hot and cold impact, microbes and the like, good fire resistance and flame-retardant effect, no smoke, no odor and long service life. Meanwhile, according to a preparation method for the threading pipe, the raw material used in the method are safe, reliable, harmless to environment and low in cost; the method is easy to operate and suitable for industrial production; so the preparation method has high practical value and good application prospects.

Description

technical field [0001] The invention relates to the technical field of power materials, in particular to a flame-retardant and weather-resistant high-strength power threading pipe and a preparation method thereof. Background technique [0002] Wires buried in the wall must be threaded through pipes, because no matter how good the circuit quality is, it is difficult to guarantee that there will be failures in the future, and the circuit needs to be replaced. Avoid causing "dead lines" that cannot be pulled in the future. [0003] Most of today's buried wire and cable threading pipes are polyvinyl chloride pipes (the main raw material is polyvinyl chloride, using lead and cadmium stabilizers, and then adding other necessary additives, and extruded. The pipes are generally orange-red, The maximum specification size is Φ219×9.5mm, and the pipe length is generally 6m. The main raw material is polyvinyl chloride resin, which is difficult to process and has low impact strength. Du...
