Wear-resistant and flame-retardant resin composition, method of manufacturing resin composition, and insulated electric wire

摘要

A wear-resistant and flame-retardant resin composition formed by kneading components (a) through (e) at a proportion in a specific range, wherein: the component (a) is a copolymer of ethylene and alpha -olefin having a melt index in a range of 0.1 - 5 g/10 min., containing comonomers in a range of 10 - 30 wt%, and containing one or more oxygen atoms in the molecule, the component (b) is linear chain polyethylene of low density having a melt index in a range of 0.1 - 5 g/10 min., a density in a range of 0.920 - 0.945, and a durometer hardness of 50 - 65, the component (c) is polyolefin having a durometer hardness of not less than 60, the component (d) is unsaturated carboxylic acid or polyolefin modified by a derivative thereof, and the component (e) is a metal hydroxide. The composition is used as an insulating coating on an electric wire.
