Cable sheath material and preparation method thereof

Abstract

The invention provides a cable sheath material and a preparation method thereof. The cable sheath material comprises 70 to 90 parts of PVC resin, 20 to 40 parts of an elastomer composition, 30 to 40 parts of nanofiber, 1 to 1.5 parts of sulfur powder, 30 to 40 parts of nanometer silica, 30 to 35 parts of organic bentonite, 1.5 to 2 parts of methyl silicone oil, 30 to 50 parts of a fire retardant, 1.5 to 6 parts of a crosslinking sensitizer, 2 to 4 parts of a smoke suppressing agent, 7 to 11 parts of furfuryl alcohol extracted from natural plants, 15 to 18 parts of glutaric acid, 5 to 7 parts of zinc oxide powder, 2 to 3 parts of softening oil, 15 to 20 parts of dimethyl carbonate, 4 to 8 parts of acetic ester, 1 to 4 parts of an emulsifier, 1 to 2 parts of an antioxidant and 1 to 2 parts of a promoter. The cable sheath material provided by the invention uses environment-friendly raw materials, poses little pollution to environment in burying, and shows high tensile strength and tearing strength and good aging resistance in usage.

Description

technical field [0001] The invention relates to the technical field of wires and cables, in particular to a cable sheathing material and a preparation method thereof. Background technique [0002] In the face of increasingly severe energy, environment, and climate change, the development of new energy vehicles has gradually become a global consensus. As one of the solutions, the popularization of electric vehicles will have a positive and far-reaching impact on new energy applications and transportation systems, and will also bring good development opportunities for the industry of electric vehicle-related conductive charging system products.

It is one of the key equipment of the electric vehicle conductive charging system. The performance of this type of product will have a direct impact on the safe and reliable operation of t...

AI Technical Summary

Problems solved by technology

At present, ethylene-propylene rubber, neoprene, PVC, low-smoke halogen-free polyolefin, TPU, TPE and other materials can be used as the cable sheath material for electric vehicle conductive charging system, among which PVC material is famous for its excellent physical properties and processing performance , low price, has gained widespread attention; but PVC contains halogens, which will produce harmful gases such as dioxins after burning

And during use, due to friction with other objects, the surface of the cable sheath is damaged or even loses its original performance, and the aging speed becomes faster after being used for too long, and the discarded cable sheath is not easy to degrade after being buried. polluted environment
