Document Type and Number:

WIPO Patent Application WO/2017/171199

Kind Code:

A1

Abstract:

The present invention relates to: a method for manufacturing a multilayer insulated electric wire insulated by a biopolyester resin; and a multilayer insulated electric wire insulated by a biopolyester resin, manufactured according thereto, the method comprising the steps of: separating glycerol from biodiesel by-products; separating bio 1,3-propanediol by fermenting the glycerol; preparing a biopolyester resin by means of a transesterification reaction step, using the bio 1,3-propanediol, and a polycondensation reaction step; preparing biopolyester pellets by obtaining a mixture by mixing the biopolyester resin with an antioxidant and a pigment, and then melt mixing the mixture; and forming two or more layers of insulation layers by extruding the biopolyester pellets on the outer circumference of a conductor, and then forming an outermost insulation layer by extruding polymer resin pellets on the insulation layers. According to the present invention, a multilayer insulated electric wire satisfying environmental protection requirements and simultaneously having the necessary characteristics such as heat resistance and impact resistance, flexibility before and after heating, and scratch resistance, which are required for a use as battery and electronic equipment wiring and coiling, can be readily manufactured.
