Problems solved by technology

[0003] Traditional cable materials are mainly made of resin materials, fillers, plasticizers, anti-aging agents, flame retardants, and antioxidants. The formula raw materials are mainly concentrated in some common ingredients, which leads to low technical indicators or high costs of cables. Problems, such as low volume resistivity, high temperature resistance, low temperature resistance, flame retardancy, insulation, etc., cannot meet the requirements of cable manufacturers for higher electrical properties of insulating grade sheath materials
There are also the following problems in the traditional production process: large processing volume, high production cost; not conducive to the assembly of finished products, long production cycle; large volume, waste of materials, electricity, space, cable bridges, pipelines and labor for production and laying

Abstract

The invention discloses a flexible composite cable, which mainly includes a cable core, and the outside of the cable core is coated with a coating layer and an outer sheath in sequence, and the cable core is composed of a conductor and an insulating layer, wherein: the coating layer contains polyphenylene ether Resin, polyolefin elastomer, filler type flame retardant, synergistic flame retardant, toughening agent, antioxidant and compound rare earth components, the insulating layer is cross-linked polyethylene insulating layer, and the material of the outer sheath is halogen-free Low-smoke flame-retardant polyolefin; the invention also designs a preparation method of flexible composite cable, preheating the conductor and extruding a layer of cross-linked polyethylene insulating layer on the surface of the conductor to shape the cable core, and cooling the cable core to room temperature , spray a layer of coating layer on the surface of the cooled cable core, and put a layer of outer sheath on the outer periphery of the coating layer after drying to make a finished cable; the cable has good bending flexibility, good flame retardancy, and high temperature resistance , Low temperature resistance, simple manufacture, and the flexible composite cable is easy to lay, install and manage, and can achieve excellent electrical performance and long service life when used.

Description

technical field [0001] The invention relates to a cable and a preparation method thereof, in particular to a flexible composite cable and a preparation method thereof. Background technique [0002] As we all know, cables are the basis of data communication. Whether in power engineering, remote control, or construction engineering, the power supply system is particularly important during the construction process or after being put into use. The cable is the carrier of the power supply system. The strong current system and the weak current system are controlled by power cables and cable to control. [0003] Traditional cable materials are mainly made of resin materials, fillers, plasticizers, anti-aging agents, flame retardants, and antioxidants. The formula raw materials are mainly concentrated in some common ingredients, which leads to low technical indicators or high costs of cables. Problems, such as low volume resistivity, high temperature resistance, low temperature res...
