High-effect rat-proof and termite-proof electric wire and cable and preparation method thereof

Abstract

The invention provides a high-effect rat-proof and termite-proof electric wire and cable which comprises conductors. A shielding layer is arranged outside each conductor, a flame-resistant PE (polyethylene) insulating layer is arranged outside each shielding layer, a ceramic silicone rubber layer is arranged outside each flame-resistant PE insulating layer, a waterproof layer is arranged outside each ceramic silicone rubber layer, the conductors are filled with a flame-resistant glass fiber filler rope, a flame-resistant belt is arranged outside the conductors and the flame-resistant glass fiber filled rope, a mica layer is arranged outside the flame-resistant belt, a flame-resistant PE protection layer is arranged outside the mica layer, an armor layer is arranged outside the flame-resistant PE protection layer, a nylon 12 sheath layer is arranged outside the armor layer, a carbon pipe is arranged outside the nylon 12 sheath layer, and a capsaicin rat-proof and termite-proof layer is arranged outside the carbon pipe. The invention further provides a preparation method of the electric wire and cable. The high-effect rat-proof and termite-proof electric wire and cable is provided with multiple rat-proof and termite-proof layers and multiple flame-resistant layers.

Description

[0001] technical field [0002] The invention relates to a wire and cable and a preparation method thereof, in particular to a high-efficiency rodent-proof wire and cable and a preparation method thereof. Background technique [0003] Wire and cable is a wire product used to transmit electric (magnetic) energy, information and realize electromagnetic energy conversion. As the main carrier of power transmission, wire and cable are widely used in electrical equipment, lighting circuits, household appliances, etc. The quality of wire and cable directly affects the quality of the project and the safety of consumers' lives and property. Although the wire and cable industry is only a supporting industry, it accounts for 1 / 4 of the output value of China's electrical industry. It has a wide variety of products and a wide range of applications, involving industries such as electric power, construction, communications, and manufacturing, and is closely related to various sectors of t...

Problems solved by technology

[0005] In order to protect wires and cables, the current wire and cable industry has also derived anti-termite and anti-mouse cables. In the past, anti-termite and anti-mouse cables usually use PVC as Base material, add anti-termite agents such as dieldrin, aldrin, lindane, chlordane and other chlorine-containing alicyclic or aromatic heterocyclic compounds to the outer wall material of the wire and cable. These compounds have a strong pungent odor and are What's more, it is also toxic. While preventing and controlling the harm of termites and mice, it also causes harm to environmental pollution and human health. Therefore, it is necessary to develop some environmentally friendly drugs

In the past, anti-termite and anti-mouse cables usually have a layer of metal sheath on the outer wall of the wire and cable, but these metal sheaths cannot be bent, which brings inconvenience to long-distance transportation

[0006] At the same time, although the cost of the PVC material used in the past cables is low, PVC contains halogen elements, so the corrosive and poisonous gas
