Abstract

The present invention provides a composition for an electric wire protection material, an electric wire protection material, and a wire harness that have heat resistance, flame retardancy, calcium chloride resistance, and resistance to braided wires. The composition for electric wire protection materials is composed of: polypropylene, 50 to 95% by mass of monomers are propylene monomers, MFR is 0.5 to 5 g / 10 minutes, and melting point is 150° C. or higher; brominated flame retardants and three antimony oxide; phenolic antioxidant; and metal deactivator, the tensile strength of the above-mentioned polypropylene is 20-35MPa, and the Charpy impact strength at 23°C is 10kJ / m 2 As above, with respect to 100 parts by mass of the above-mentioned polypropylene, a total of 1.5 to 15 parts by mass of the above-mentioned brominated flame retardant and the above-mentioned antimony trioxide, 0.1 to 3 parts by mass of the above-mentioned phenolic antioxidant and 0.1 to 3 parts by mass of The above metal passivators.

Description

technical field [0001] The present invention relates to a wire protection material for protecting vehicle parts of motor vehicles, electric / electronic equipment components, etc., for protecting wire bundles such as corrugated tubes, a composition for wire protection materials used for the wire protection material, and the use of the above-mentioned Wire harness for wire protection material. Background technique [0002] Conventionally, as a protective material for electric wires of automobiles, as described in Patent Document 1, a flame-retardant corrugated tube made of a flame-retardant composition obtained by blending a specific bromine-based flame retardant into polyolefin is known. Although this flame-retardant bellows has flame retardancy, since polyolefin is used, the heat resistance range at a temperature that can be used continuously is generally about 80 to 90°C. Wire protection materials require higher heat resistance. [0003] In recent years, the demand for veh...
