In recent years, with the development of economy and the improvement of environmental awareness, the requirements on wires and cables used in production and life are higher and higher; the environment-friendly wind vane has become a wind vane in the wire and cable industry. Polyolefin is a plastic with wide source and easy processing, and is widely applied to the wire and cable industry due to excellent electrical property and mechanical property. However, polyolefin materials also have the obvious disadvantages of poor flame retardant performance and flammability when exposed to fire, and when used as materials for electric wires and cables, the polyolefin materials are easy to cause fire and cause immeasurable loss to human bodies and property. The fireproof flame retardance of the cable material can be improved to a certain extent by adding the flame retardant into the polyolefin material, but the processing flowability and the performance stability of the material are influenced by adding a large amount of the flame retardant. Therefore, how to solve the problem of flame retardancy of the wire and cable becomes a problem which the wire and cable manufacturing enterprises have to face.
The PVC cable material is a common flame-retardant cable material in the market at present, and is prepared by taking polyvinyl chloride as basic resin, adding a stabilizer, dioctyl phthalate, diisodecyl phthalate, dioctyl terephthalate, trioctyl trimellitate and other plasticizers, calcium carbonate and other inorganic fillers, an auxiliary agent, a lubricant and other additives, and mixing, kneading and extruding the mixture. The material has the advantages of good price performance, low manufacturing cost, corrosion resistance, insulation and the like, however, PVC contains halogen, and a large amount of smoke and toxic and corrosive gas are released during combustion, are dangerous factors in fire, and can hinder safe evacuation and fire extinguishing work of people in the fire, so that lives and properties are seriously lost. In addition, PVC has poor thermal stability, can be decomposed at the temperature of more than 100 ℃ to generate hydrogen chloride, further can be subjected to autocatalytic decomposition to cause discoloration, and has rapidly reduced physical and mechanical properties.

The flame-retardant PVC power cable has good flame retardance and is very suitable for being used in the fields of factories, mines, engineering and the like. However, the PVC power cable disclosed by the invention is not added with a heat stabilizer, and the thermal stability is poor.
