Modified polyethylene insulating material for wire harness of communication equipment

Abstract

The invention relates to an insulating material for a wire harness, and specifically relates to a modified polyethylene insulating material for a wire harness of communication equipment. The material comprises the following raw materials in parts by weight: 24-28 parts of medium density polyethylene, 12-16 parts of metallocene linear low density polyethylene, 5-9 parts of polyphenylene sulfide, 5-6 parts of cellulose acetate, 16-19 parts of polystyrene, 2-3 parts of an antioxidant 1010, 5-6 parts of hydrogenated rosin, 3-4 parts of coumarone, 30-34 parts of tributyl citrate, 1-3 parts of potassium stearate, 5-10 parts of aluminum nitride, 3-4 parts of zinc borate, 12-15 parts of zinc pyrophosphate, 23-26 parts of carbon black N330 and 14-16 parts of an assistant. The insulating material combines the advantages of the raw materials such as medium density polyethylene and polystyrene and enhances the performance of conventional polystyrene blending materials; and the prepared material is high in strength, impact-resistant, good in toughness, good in electric insulation, chemical-corrosion-resistant, ageing-resistant and long in service life, can be widely applied to manufacture of insulating sheathes, terminals, bandage materials and the like of wire harnesses at all parts of the communication equipment, and is wide in market requirement prospect.

[0002] The wiring harness of communication equipment is the wiring part of each equipment, and its role is very important. With the rapid development of the communication industry, its market demand is gradually increasing, and the quality requirements are getting higher and higher, especially for safety and environmental protection issues. Including wires, insulating sheaths, wrapping materials and other components, in practical applications, parts of suitable materials should be selected according to the working environment and performance requirements of the wiring harness. Traditional communication equipment wiring harness insulation materials often have poor flame retardancy and high temperature deformation. , short service life and other problems, bring a lot of inconvenience to the actual use, and even threaten the safety of people's lives and property. Therefore, it is urgent to change the original formula and improve the performance of materials to meet the diverse needs of the communication equipment and electronic device market.
