Abstract

The invention provides a high-temperature-resistant nanometer cable material and a preparation method thereof, which relate to the technical field of cable materials. The high temperature resistant nano cable material of the present invention is made of the following raw materials: polyethylene resin, modified nano filler, modified polypropylene, elastomer, polyurethane rubber, flame retardant, toughening agent, antioxidant and stabilizer. The high-temperature-resistant nano-cable material of the present invention has good mechanical properties and good processing performance, and can be widely used in cables used in high-temperature environments in the fields of electric power grids, metallurgy, and chemical industry, and not only has excellent high-temperature resistance and fire-proof properties, Moreover, it has strong wire core firmness, which ensures that the cable does not deviate from the original set position under normal use and extrusion by external force, and improves the safety of the cable.

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a high-temperature-resistant nano-cable material and a preparation method thereof. Background technique [0002] The cable is the system that connects the power system from the step-down distribution substation to the user end. Most of the cables in the transmission line are placed between two utility poles, and most of them are exposed to the outdoors. Once damaged, it will cause hidden dangers to the power supply system and people’s safety. Therefore, the power grid department has extremely high performance requirements for cable materials and should have relatively high Good high temperature and cold resistance, good mechanical properties and insulation flame retardant properties. [0003] At present, wires and cables are insulated with plastic and rubber. These materials are conventional engineering materials with abundant sources, which can not only meet mass produc...
