Flame-retardant silane-crosslinked polyolefin-based resin composition and insulated wire

摘要

PROBLEM TO BE SOLVED: To provide a flame retarding silane crosslinked polyolefin resin composition hardly blooming an oxidation inhibitor and obtaining high heat resistance, and an insulated electric wire using the flame retarding silane crosslinked polyolefin resin composition as an insulator.;SOLUTION: This flame retarding silane crosslinked polyolefin resin composition contains a polyolefin resin containing a silane graft polymer obtained by graft-polymerizing an olefin resin with a silane coupler, the hindered phenol resin oxidation inhibitor and the semi-hindered phenol resin oxidation inhibitor, a blooming inhibitor comprising zinc oxide and zinc sulfide, a flame retarder comprising a metal hydroxide, and a cross-linking catalyst. The composition is subjected to crosslinking by kneading and heating with water, and a crosslinked polyolefin resin is obtained thereby to be used in the insulated electric wire as the insulator.;COPYRIGHT: (C)2009,JPO&INPIT
