Wear-resistant PVC (polyvinyl chloride) insulation material for wire harnesses of electromechanical device

Abstract

The invention relates to a wear-resistant PVC (polyvinyl chloride) insulation material for wire harnesses of an electromechanical device. The insulation material comprises raw materials in parts by weight as follows: 34-38 parts of PVC, 10-12 parts of metallocene linear high-density polyethylene, 5-7 parts of polystyrene, 5-8 parts of 2,2'-dithiobis(benzothiazole), 3-4 parts of stearic acid, 12-15parts of titanium dioxide, 3-5 parts of silicone rubber masterbatch, 13-14 parts of dioctyl phthalate, 2-3 parts of zinc oxide, 1-2 parts of accelerator M, 1-2 parts of silane coupling agent KH-550,11-12 parts of isopropyl tri(dioctylpyrophosphate) titanate, 2-3 parts of methyl phenyl silicone oil, 0.5-1 part of diisopropyl peroxydicarbonate, 21-24 parts of sepiolite powder and 14-16 parts of anassistant. The insulation material is flexible, wear-resistant, good in mechanical property and resistant to low-temperature brittleness and chemical corrosion, can be widely used for preparing insulating sheaths for the wire harnesses at all parts of the electromechanical device, wiring terminals, surgical dressings and the like, and has broad market requirement prospect.

[0002] The wiring harness of electromechanical equipment is the wiring part of each equipment, and its role is very important. With the rapid development of the manufacturing 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 electromechanical 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 electromechanical equipment and electronic device market.
