Wear-resistant anti-cracking cable material and preparation method thereof

Abstract

A wear-resistant anti-cracking cable material is made of, by weight parts, 3-4 parts of nano-titania, 3-4 parts of asphalt, 6-8 parts of zirconium silicate, 6-7 parts of aluminum hydroxide, 9-10 parts of polyacrylonitrile, 6-7 parts of polylactic acid, 3-4 parts of polyethylene oxide, an appropriate amount of methyl methacrylate, an appropriate amount of complex solvent with methyl methacrylate and dichloromethane at a volume ratio of 1:1, an appropriate amount of methyl methacrylate, an appropriate amount of isopropylthioxanthone, 20-25 parts of ethylene-vinyl acetate copolymer and 80-85 parts of low density polyethylene. By use of zirconium silicate, heat resistance and wear resistance of the cable material are improved; by adding of aluminum hydroxide, the flame retardance of the cable material is improved, and poison gas is not decomposed; by use of nano-titania and asphalt, the toughness is improved, and cracking is avoided.

Description

technical field [0001] The invention relates to the field of cable materials, in particular to a wear-resistant and anti-cracking cable material and a preparation method thereof. Background technique [0002] Plastics for wire and cable insulation and sheathing are commonly known as cable materials, including rubber, plastic, nylon and other varieties. With the development of society, wires and cables are more and more widely used in various fields, such as transportation, communication, construction, etc. Therefore, the requirements for the professional field of wires and cables are also getting higher and higher. It is subject to external pressure, tension, bending, collision, beating, etc., and the cable material will withstand the test of heat and cold, light, chemicals, water, voltage and other environments during use, and it will be scratched, corroded, worn, broken, Cracking, aging, burning, breakdown leakage and other phenomena need to improve the performance of cab...

AI Technical Summary

Problems solved by technology

[0003] In the practical application of low-smoke, halogen-free and flame-retardant polyolefin cable sheathing materials, it often faces the problem that the mechanical properties, processing properties and flame-retardant properties are mutually restricted and cannot be balanced

In order to obtain the best balance between mechanical properties and flame retardant properties on the basis of meeting the basic performance requirements, the commonly used methods are: surface coupling treatment of inorganic flame retardant fillers, use of compatibilizers, etc. This method cannot completely solve the problem of inorganic flame retardant. Combination properties of fuel fillers and plastics

Other fillers will also have the same compatibility problems, and it is necessary to improve the process to improve the mechanical properties of the cable material
