Electric wire for automobile
View Patent ↗The present invention provides an electric wire for an automobile. Specifically, the present invention provides an electric wire for an automobile coated with a composition comprising (A) 100 parts by weight of a mixture of 1 to 30 parts by weight of a maleic acid-modified polypropylene resin and a polyolefin-based resin other than the maleic acid-modified polypropylene resin, (B) 10 to 80 parts by weight of a halogen-based flame retardant, and (C) 5 to 45 parts by weight of a metal hydrate flame retardant.
1. An electric wire for an automobile, coated with a composition comprising (A) 100 parts by weight of a mixture of 1 to 30 parts by weight of a maleic acid-modified polypropylene resin and a polyolefin-based resin other than the maleic acid-modified polypropylene resin, (B) 10 to 80 parts by weight of a halogen-based flame retardant, and (C) 5 to 45 parts by weight of a metal hydrate flame retardant.
2. The electric wire according claim 1 , wherein a mixing amount of the maleic acid-modified polypropylene resin is 5 to 10 parts by weight.
3. The electric wire according claim 1 , wherein the polyolefin-based resin other than the maleic acid-modified polypropylene resin is at least one compound selected from a polypropylene-based resin other than the maleic acid-modified polypropylene-based resin, an olefin-based thermoplastic elastomer, and a styrene-based thermoplastic elastomer.
4. The electric wire according claim 3 , wherein the polypropylene-based resin other than the maleic acid-modified polypropylene-based resin is at least one compound selected from a polypropylene homopolymer and a copolymer of propylene with a monomer copolymerizable with propylene.
5. The electric wire according claim 1 , wherein a mixing amount of the halogen-based flame retardant is 20 to 50 parts by weight.
6. The electric wire according claim 1 , wherein a mixing amount of the metal hydrate flame retardant is 20 to 30 parts by weight.
