Abstract

Disclosed are a composition for use in a wire coating material, an insulated wire and a wire harness. The disclosed composition achieves excellent heat resistance, good productivity, and flame resistance without using electron beam crosslinking. After the composition for use in a wire coating material is extrusion molded around a conductor to form the coating material, and water crosslinking is performed to create the insulated wire. The composition for wire coating material contains (A) water crosslinked polyolefins formed by modifying a polyolefin with a silane coupling agent, (B) unmodified polyolefins, (C) modified polyolefins modified with functional groups, (D1) a brominated flame retardant, (E) a crosslinking catalyst, (F) a phenolic antioxidant, and (G) (G1) a zinc sulphide or (G2) a zinc oxide-imidazole compound.

Description

Technical field [0001] The present invention relates to a composition for a wire coating member, an insulated wire, and a wire harness. More specifically, the present invention relates to a composition for a wire coating member, an insulated wire using the same, and a wire harness using the same, and the combination for the wire coating member The compound is advantageously used as a covering member for insulated wires for automobiles that require heat resistance, and has excellent properties such as flame retardancy, mechanical strength, heat resistance, and chemical resistance. Background technique [0002] Currently, hybrid vehicles have become common, and therefore, wires and connectors used in automobiles are required to have high voltage resistance and high heat resistance. Generally, polyvinyl chloride (PVC) cross-linked wires or polyolefin cross-linked wires are used in places where high temperatures are generated, such as wiring harnesses in automobiles. These wires are...
