Abstract

The invention discloses an electronic connecting wire with high thermal aging resistance and high toughness. The electronic connecting wire comprises a conductor, an insulation layer coating the conductor and a jacket layer coating the insulation layer. The outer jacket layer of the electronic connecting wire has better mechanical strength, certain flexibility, excellent heat resistance, stress crack resistance, (thermal) aging resistance and the like and long service life; the inner insulation layer has better heat resistance and (thermal) aging resistance and certain flexibility, and tensileperformance and bending performance of the electronic connecting wire in daily use can be met; the jacket layer and the insulation layer have good flame retardance and electric insulation continuity,and the electronic connecting wire prepared from the jacket layer and the insulation layer which have good combination properties has good use safety; the jacket layer material and the insulation layer material are re-processed through two times of crosslinking without vulcanization, a production method is simple, and the electronic connecting wire is convenient to process and use.

Description

technical field [0001] The invention relates to the technical field of electronic connection wires, in particular to an electronic connection wire with high heat aging resistance and toughness.
