  • Publication number: 20130273367
    Abstract: To provide a composition for a wire coating material, requiring no electron irradiation crosslinking and a less filler, that can produce a crosslinked coat having a high heat resistance, gel fraction and peel property at high temperature, and provide an insulated wire, and a wiring harness. A wire coating material composition contains (A) silane-grafted polyolefin, (B) undenatured polyolefin, (C) functional-group modified polyolefin modified by functional groups of 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 the flame retardant and an antimony trioxide, (E) a crosslinking catalyst batch containing a resin containing a crosslinking catalyst, and (F) a zinc oxide and an imidazole compound or a zinc sulfide, (G) a triazine hindered phenolic antioxidant having a melting point of 150 degrees C. or more, and (H) a triazole derivative or a hydrazide metal deactivator.

  • Publication number: 20130161064
    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.

  • Publication number: 20120273268
    Abstract: A composition for a wire coating member having flame retardancy that is heat resistant and productive without using electron irradiation crosslinking, and an insulated wire and a wiring harness having the same. The insulated wire includes a wire coating member containing the composition for the wire coating member that contains water-crosslinkable polyolefin containing polyolefin that is modified by a silane coupling agent, unmodified polyolefin, modified polyolefin that is modified by a functional group, a bromine flame retardant, a cross-linking catalyst, a phenolic antioxidant, and either one of a zinc sulfide, and a zinc oxide and an imidazole compound. The insulated wire is prepared by extrusion-coating a conductor with the composition to form the wire coating member around the conductor, and the wire coating member is water-crosslinked.

  • Publication number: 20120241190
    Abstract: Provided is a composition for a wire coating material that is capable of achieving heat resistance and a mechanical property at the same time even if silane crosslinking and magnesium hydroxide that is made from a natural mineral are used in combination. The composition contains (A) silane-grafted polyolefin that defines polyolefin onto which a silane coupling agent is grafted, (B) unmodified polyolefin, (C) modified polyolefin that is modified by a functional group, (D) magnesium hydroxide that is made from a natural mineral, and (E) a cross-linking catalyst. Provided is an insulated wire including a wire coating material that contains the composition that is silane-crosslinked. Provided is a wiring harness including the insulated wire.

  • Publication number: 20110056728
    Abstract: A flame-retardant composition that is more excellent in heat resistance than a conventional flame-retardant composition. The flame-retardant composition contains silane-crosslinked polyolefin, polyolefin, a metallic hydrate, a phenolic antioxidant, a sulfurous antioxidant, a metallic oxide, and a copper inhibitor. The sulfurous antioxidant is preferably a benzimidazole compound, and the metallic oxide is preferably a zinc oxide. The silane-crosslinked polyolefin is preferably polyethylene having a density of 0.880 to 0.910 g/cm3 that is silane-crosslinked. The polyolefin is preferably polyethylene having a density of 0.880 to 0.910 g/cm3, or an olefin elastomer having a melting point of 140° C. or more.
