Cable protection pipe material and cable protection pipe made of material

Abstract

The invention discloses a cable protection pipe material and a cable protection pipe made of the material. The cable protection pipe material comprises the following constituents in parts by weight: 50-60 parts of high-polymerization-degree polyvinyl chloride with a polymerization degree of 2300-2700, a chlorine mass fraction of which is 65-68%, 40-50 parts of chlorinated polyvinyl chloride with a polymerization degree of 650-750, 4-9 parts of polyacrylic rubber with a rubber mass fraction of 80-90%, 1-2 parts of acrylic copolymer ACR401, 0.3-0.5 part of methyl tin mercaptide, 0.5-0.7 part of oxidized polyethylene, 0.4-0.6 part of stearic acid, 0.3-0.5 part of low-molecular-weight polyethylene, 2.5-3.5 parts of chlorinated paraffin with a chlorine mass fraction of 70%, and 10-20 parts of micron-scale activated chalk. The prepared cable protection pipe material is free of heavy metals such as lead and cadmium, can meet the requirements on the cable protection pipe, is low in the raw material cost, and has excellent economic benefits.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a wire and cable protection tube material, and also relates to a wire and cable protection tube made from the material. Background technique [0002] The wire and cable protection tube is installed on the surface of the power line or communication cable to prevent short-circuit accidents caused by disconnection of the power line, so as to protect the cable and the whole machine from being burned out, and also play a certain role in isolating the magnetic field interference of the power line. Most of my country's buried wire and cable protection tubes are chlorinated polyvinyl chloride pipes (PVC-C), the main raw material is chlorinated polyvinyl chloride, using lead and cadmium stabilizers, and then adding other necessary additives, after extrusion processing made. The pipe is generally orange-red, the maximum size is Φ219×9.5mm, and the length of the pipe is generally 6m. T...

AI Technical Summary

Problems solved by technology

However, most of these wire and cable protection tubes are straight and have no flexibility. It is inconvenient to install and lay underground, and it is also inconvenient to change and maintain the wire and cable after being buried.

Moreover, the main raw material is chlorinated polyvinyl chloride resin, the processing of the pipe is difficult, and the impact strength of the pipe is low

In order to reduce the difficulty of pipe processing and improve the impact strength, it is necessary to add a considerable amount of acrylate processing modifier and impact modifier, but the price of the two types of modifiers is high, which increases the raw material cost of the pipe, and at the same time contains lead Cadmium stabilizer, which is contrary to my country's purpose of non-toxic PVC-U pipes
