Problems solved by technology

[0005] However, ordinary glass fiber, ceramic bowl, carbon fiber and other inorganic fibers generally have the disadvantages of high fiber surface smoothness, poor compatibilizer with resin matrix materials, and insufficient bonding strength due to the limitation of processing technology; Floating fiber phenomenon will occur when the cable material is reduced in strength, thermal stability and anti-aging performance

Abstract

The invention relates to the technical field of wire and cable materials, in particular to a high-toughness high temperature resistant cable material which comprises the following components: an ethylene-propylene-diene monomer, polyethylene resin, vulcanizing silicone rubber, white carbon black, a heat-resistant filler, a toughened fiber, a composite flame retardant, a silane coupling agent, a lubricating dispersant and a Ca-Zn composite stabilizer, wherein the heat-resistant filler comprises the following components: calcined kaolin, nanometer aluminum oxide, N-phenylmaleimide and dibutyltindilaurate; and the lubricating disperse is a mixture of glyceryl tristearate and ethylene bis oleamide according to equal mass ratio. The toughed fiber is a special ceramic fiber subjected to surfaceroughening and dendronization. Through the use of the toughed fiber, the toughness, the high temperature resistance and the ageing resistance of the cable material are greatly improved.

Description

Technical field [0001] The invention relates to the technical field of wire and cable materials, in particular to a high-toughness high-temperature resistant cable material. Background technique [0002] Cables include power cables, control cables, compensation cables, shielded cables, signal cables and other different types according to their uses. Cable materials are commonly known as plastics for wire and cable insulation and sheaths. The polymer materials used mainly include polyolefins, fluoroplastics, and Polyether, rubber and polyamide, etc., this kind of polymer material has the characteristics of light weight, good insulation performance, chemical corrosion resistance, easy processing, excellent mechanics and fatigue resistance. [0003] However, due to the limitation of the material's own properties, the high temperature resistance of the cable material is generally poor. Under high temperature conditions, the bonding performance between the components of the cable materi...
