Toughened and flame-retardant insulation material for household appliance harness

Abstract

The invention relates to a toughened and flame-retardant insulation material for household appliance harness. The toughened and flame-retardant insulation material comprises the following raw materials by weight: 23-35 parts of polystyrene, 4-7 parts of polyimide, 1-3 parts of polybutylene terephthalate, 11-14 parts of glycerol triacetate, 7-9 parts of an SEBS thermoplastic elastomer, 9-13 parts of montmorillonite, 5-8 parts of magnesium hydroxide, 1-2 parts of an accelerator M, 2-4 parts of methyl phenyl silicone oil, 2-5 parts of silicon carbide, 12-16 parts of activated calcium carbonate, and 9-14 parts of an assistant. The insulation material for household appliance harness provided by the invention has the advantages of high tensile strength, excellent heat resistance and processability, improved flame retardant level and long service life, can be widely used for making insulation sheaths, wiring terminals, binding materials and the like of harness at all parts of household appliances, and has a broad market demand prospective.

[0002] The home wire harness is the wiring part that connects various electrical equipment in electrical appliances. Its role is very important. With the rapid development of the home appliance industry, its market demand is gradually increasing, and the quality requirements are also getting higher and higher, especially the safety and environmental protection issues. , the wire harness mainly includes 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 wire harness. Traditional home wire harness insulation materials often have poor flame retardancy and high temperature. Problems such as easy deformation and short service life bring a lot of inconvenience to actual use, and even threaten people's life and property safety. Therefore, it is urgent to change the original formula and improve material properties to meet the diverse needs of the home appliance and electronic device market.
