Abstract

The invention discloses a thermoplastic polyeher ester elastomer automobile antenna and a preparation method thereof. The preparation method for the thermoplastic polyeher ester elastomer automobile antenna comprises the following steps of: wrapping thermoplastic polyeher ester elastomer material onto the surface of a stranded conductor; enabling the thermoplastic polyeher ester elastomer material to be in cross-linking by electron beam irradiation to form an insulation layer, wherein the average thickness of the insulation layer is 0.22-0.42mm, and the gel content of the cross-linking thermoplastic polyeher ester elastomer material is 10-80%. The preparation method disclosed by the invention does not have the rigorous requirement on the raw material, no processing aids are added, the prepared TPEE (thermoplastic polyeher ester elastomer) automobile antenna has the advantages of excellent combination property, low fogging performance and good hydrolysis resistance, the temperature resistance grade can reach 150DEG C, and the TPEE automobile antenna can pass the thermal overload test of the automobile antenna.

Description

technical field [0001] The invention relates to an automobile wire, in particular to a thermoplastic polyester elastomer automobile wire. Background technique [0002] Thermoplastic polyester elastomers (thermoplasticpolyetheresterelastomers, referred to as TPEE) are a class of block copolymers containing aromatic polyester hard segments (crystalline phase) and aliphatic or polyether soft segments (continuous phase). TPEE has excellent mechanical properties and heat resistance, and is very suitable for use as an insulating material on automotive wires in the engine and lamp parts. The automotive wires of the car lights also require that the insulating material has low fogging properties, that is, when used at high temperatures, the low molecular weight volatiles of the insulating material are kept at a low level to prevent the low molecular weight volatiles from condensing and coating the transparent lampshade of the car lamp On, affecting the normal use of lights. At pres...
