Abstract

To provide a composition for a wire coating material, which requires no electron irradiation crosslinking, and requires a filler defining a flame retardant agent as less as possible, and from which an insulated wire having a high heat resistance and a high gel fraction can be produced, and to provide an insulated wire and a wiring harness containing the composition. The composition contains (A) silane-grafted polyolefin, which is polyolefin to which a silane coupling agent is grafted, (B) undenatured polyolefin, (C) functional-group modified polyolefin modified by one or more functional groups selected from a carboxylic acid group, an acid anhydride group, an amino group, and an epoxy group, (D) a bromine flame retardant having a phthalimide structure, or a bromine flame retardant having a phthalimide structure and an antimony trioxide, (E) a crosslinking catalyst, and (F) a zinc sulfide, or a zinc oxide and an imidazole compound.

Description

technical field [0001] The present invention relates to a composition for an electric wire covering material, an insulated electric wire, and a wire harness. More specifically, the present invention relates to an electric wire suitable as a covering material for an insulated electric wire used in a place requiring high heat resistance, such as a wire harness of an automobile. Compositions for covering materials, insulating wires and wire harnesses. Background technique [0002] Conventionally, cross-linked wires made of vinyl chloride resin and polyolefin cross-linked wires have been used as insulated wires used in places where high temperatures occur, such as wiring harnesses for automobiles. Among these crosslinking methods for insulated electric wires, crosslinking with electron beams is the mainstream. [0003] However, electron beam crosslinking requires an expensive electron beam crosslinking apparatus and the like, and therefore there is a problem that the cost of eq...
