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.

Description

technical field [0001] The invention relates to an insulating material for wire harnesses, in particular to a modified polystyrene insulating material for toughening and flame-retardant household wire harnesses and a preparation method thereof. Background technique [0002] Household wire harness is the wiring part that connects various electrical equipment in electrical appliances. Its role is very important. As the basic connecting part of the home appliance industry, its market demand is increasing with the rapid development of the home appliance industry, and its quality requirements are also increasing. High, especially for safety and environmental protection issues, the wiring harness mainly includes wires, insulating sheaths, wrapping materials and other components. There are problems such as poor flame retardancy, easy deformation at high temperature, and short service life, which bring a lot of inconvenience to actual use and even threaten people's lives and propert...
