Abstract

The invention provides a nylon composite material for wire and cable sheaths. The nylon composite material for wire and cable sheaths is characterized in that the nylon composite material comprises the following components by mass percentage: 80-90 percent of nylon, 0-2 percent of antioxidant, 0-8 percent of mold release agent, 0-5 percent of light stabilizer and 0-5 percent of viscosity increaser; nylon is long-chain nylon; the antioxidant is aromatic amine type antioxidant; the mold release agent is selected from siloxane, metallic stearate, polyvinyl alcohol, fluorine-containing oligomer, polyolefine or a mixture thereof; the light stabilizer is light-shield type light stabilizer; and the viscosity increaser is polyethylene terephthalate (PET) viscosity increaser. The wire and cable sheaths manufactured by the nylon composite material are environment-friendly, non-toxic and durable, and not only have the excellent anti-rat and anti-termite properties, but also have good physical mechanical properties.

Description

technical field [0001] The invention relates to the technical field of electric wires and cables, in particular to a nylon composite material for electric wires and cables. Background technique [0002] For a long time, anti-termite, anti-mouse, wear-resistant and corrosion-resistant are the main problems faced by wire and cable sheaths. For this reason, people add special anti-termite and anti-rodent agents into the cable sheath material to repel or reduce their taste sensitivity, thereby reducing the degree of being bitten by teeth. Or take measures such as adding armored structure or using cables with large outer diameters to achieve the purpose of avoiding rats. The above method has achieved certain effects, but due to the high toxicity of the ant-proof and rodent-proof agents, it will cause poisoning and pollution to the human body and the environment, and cannot prevent the teeth of the mice from biting, and cannot fundamentally solve the problem.
