Abstract

The invention discloses a composition and a manufacturing method of a PVC electrical conduit. The PVC electrical conduit comprises following raw materials in parts by weight: 100 parts of polyvinyl chloride (PVC) resin, 2 to 4 parts of a stabilizing agent, 4 to 6 parts of a plasticizer, 9 to 11 parts of an enhancer, 2 to 4 parts of a lubricant, and 3 to 5 parts of a processing aid. The provided composition and manufacturing method have the advantages that due to an inorganic flame retardant, the PVC electrical conduit has a good flame retardant performance, the phenomenon of spontaneous combustion of circuits caused by short circuit of internal wires and cables is prevented; due to a brightening agent and an organic toner, the PVC electrical conduit is transparent, thus during the house decoration process, people can clearly observe the direction and arrangement of wires and cables in the PVC electrical conduit, at the same time, people can find out whether the cables and wires have any joints or damages, judge whether the cables and wires need to be changed or not, and determine whether a grounding line and a lightning-shield line are completely installed; and the owners can clearly know the cost of house decoration, and can safely use the electrical conduit, and the safety of the owners is guaranteed.

Description

technical field [0001] The invention relates to the technical field of making PVC pipes, in particular to a material composition of a PVC electrical bushing and a manufacturing method thereof. Background technique [0002] PVC electrical casing is usually used as wire and cable protection tube. This product has the characteristics of high strength, good flexibility, high temperature resistance, corrosion resistance, flame retardancy, good insulation performance, no pollution, not easy to aging, light weight, and convenient construction. [0003] The PVC electrical bushings currently used are basically opaque. During the renovation, the owner cannot clearly see whether the wires and cables inside the electrical bushing have joints, whether the wires and cables are exposed or damaged, and whether they have replaced different brands of wires. , Cables, grounding wires, and lightning protection wires are installed and connected, which makes it impossible for the owner to determi...
