Abstract
A composition for manufacturing insulation materials of an electrical wire having a multilayer structure, which is used for manufacturing a first insulation coating layer made of a composition including a predetermined base resin, an antioxidant and a co-crosslinking agent so as to surround a conductor or a conductor bundle for an electrical wire; a second insulation coating layer made of a composition including a base resin polyvinylidene fluoride (PVDF), a predetermined antioxidant and a co-crosslinking agent so as to surround the first insulation coating layer, and an electrical wire manufactured using the same.

A composition for manufacturing insulation materials of an electrical wire having a multilayer structure, which is used for manufacturing a first insulation coating layer made of a composition including a base resin, an antioxidant and a co-crosslinking agent so as to surround a conductor or a conductor bundle for an electrical wire;
- a second insulation coating layer made of a composition including a base resin polyvinylidene fluoride (PVDF), an antioxidant and a co-crosslinking agent so as to surround the first insulation coating layer,
- wherein the base resin in the composition for manufacturing the first insulation coating layer is at least one mixed resin selected from the group consisting of:
- (a1) a mixed resin in which 2 to 20% by weight of an ethylene-based copolymer resin is blended with 80 to 98% by weight of polyethylene;
- (a2) a mixed resin in which 2 to 20% by weight of a modified ethylene-based copolymer resin is blended with 80 to 98% by weight of polyethylene;
- (a3) a mixed resin in which 5 to 30% by weight of modified polyethylene is blended with 70 to 95% by weight of polyethylene;
- (a4) a mixed resin in which 2 to 30% by weight of a modified ethylene copolymer resin is blended with 50 to 80% by weight of polyethylene and 2 to 20% by weight of an ethylene copolymer resin;
- and
- (a5) a mixed resin in which 5 to 40% by weight of modified polyethylene is blended with 60 to 95% by weight of an ethylene copolymer resin.
