Abstract

The present invention relates to an insulated electric wire for an automobile containing a conductor and an insulating coating layer which coats the conductor, the insulating coating layer being formed of a non-crosslinkable resin composition containing 65 to 90 parts by weight of a polypropylene-based resin, 10 to 40 parts by weight of a metal hydroxide, 20 to 50 parts by weight of a bromine-based flame retardant, 5 to 30 parts by weight of antimony trioxide, and 2 to 15 parts by weight of a maleic acid-modified resin in the ratio and further containing at least one of 3 to 10 parts by weight of a polyethylene resin and 2 to 10 parts by weight of an ethylene-based copolymer.

Claims (16)

1. An insulated electric wire for an automobile comprising a conductor and an insulating coating layer which coats the conductor, the insulating coating layer being formed of a non-crosslinkable resin composition containing

65 to 90 parts by weight of a polypropylene-based resin,

10 to 40 parts by weight of a metal hydroxide,

20 to 50 parts by weight of a bromine-based flame retardant,

5 to 30 parts by weight of antimony trioxide,

2 to 15 parts by weight of a maleic acid-modified resin,

3 to 10 parts by weight of a polyethylene resin consisting of ethylene repeating units, and

2 to 10 parts by weight of an olefin-based thermoplastic elastomer.

2. A wire harness for an automobile comprising an electric wire bundle containing a plurality of insulated electric wires and an insulating protective material containing a non-crosslinkable resin composition which protects outer periphery of the electric wire bundle, the non-crosslinkable resin composition containing

65 to 90 parts by weight of a polypropylene-based resin,

10 to 40 parts by weight of a metal hydroxide,

20 to 50 parts by weight of a bromine-based flame retardant,

5 to 30 parts by weight of antimony trioxide,

2 to 15 parts by weight of a maleic acid-modified resin,

3 to 10 parts by weight of a polyethylene resin consisting of ethylene repeating units, and

2 to 10 parts by weight of an olefin-based thermoplastic elastomer.
