Modified polystyrene insulating material for toughened flame-retardant wiring harness for household appliances

Abstract

The invention relates to an insulating material for a wiring harness, and particularly relates to a modified polystyrene insulating material for a toughened flame-retardant wiring harness for household appliances. The material comprises the following raw materials in parts by weight: 8-9 parts of polyimide, 40-45 parts of polystyrene, 10-15 parts of SBS (Styrene Butadiene Styrene), 12-15 parts of silicon dioxide, 4-6 parts of aluminum nitride, 2-3 parts of maleic anhydride, 1-2 parts of lignocelluloses, 23-25 parts of montmorillonite, 23-26 parts of talcum powder, 23-25 parts of triethyl citrate, 1-2 parts of hexamethylphosphoramide, 1-2 parts of anti-aging agent NBC, 10-12 parts of hard kaolin, 3-4 parts of nanometer argil, 1-2 parts of nadic anhydride and 14-16 parts of auxiliaries. The insulating material combines the advantages of polystyrene, SBS and other raw materials, the properties of the traditional polystyrene material can be improved, the insulating material has good processability and mechanical property, the prepared material is flexible, impact-resistant, flame-retardant, good in insulating property, anti-aging, long in service life, and can be widely used for manufacturing insulating sheaths, wiring terminals, binding materials and the like of wiring harnesses for each part of a household appliances, thus having a wide market demand prospect.
