Abstract

The invention discloses an insulation and heat dissipation material for an electric heater shell and a preparation method of the insulation and heat dissipation material, and relates to the technicalfield of insulation materials. The insulation and heat dissipation material is prepared from the following raw materials in parts: 44 to 46 parts of polyvinyl chloride, 24 to 26 parts of ABS (Acrylonitrile Butadiene Styrene) resin, 24 to 26 parts of polyethylene glycol terephthalate, 19 to 21 parts of polyimide, 15 to 20 parts of tourmaline-graphene composite powder, 10 to 15 parts of carbon fiber, 4 to 6 parts of rosin, 4 to 6 parts of lithium-based bentonite, 3 to 5 parts of zinc ethylphenyl dithiocarbamate, 3 to 5 parts of halogen flame retardant, 2 to 4 parts of anti-aging agent, 1 to 3 parts of antistatic agent, 1 to 3 parts of stabilizer and an appropriate amount of deionized water. The insulation and heat dissipation material disclosed by the invention has good heat dissipation andinsulation properties, and is not easy to deform and high in stability.

Description

technical field [0001] The invention relates to the technical field of shell materials, in particular to an insulating and heat-dissipating material for an electric heater shell and a preparation method thereof. Background technique [0002] Household appliances mainly refer to various electrical and electronic appliances used in homes and similar places. Also known as civil appliances, household appliances. Commonly used household appliances mainly include televisions, air conditioners, and refrigerators. Housings of household appliances are mostly made of synthetic plastics.
