ANTI-RAT, ABRASION-RESISTANT AND FLAME-RETARDANT RESIN COMPOSITION AND ANTI-RAT INSULATING ELECTRIC WIRE FOR AUTOMOBILE

摘要

PROBLEM TO BE SOLVED: To obtain an anti-rat, abrasion-resistant and flame-retardant resin composition useful as electric wires for automobiles.;SOLUTION: The anti-rat, abrasion-resistant and flame-retardant resin comprises 100 parts by mass of a base resin obtained by mixing 60-95 parts by mass of a homopolypropylene (PP) having ≥500% elongation at break and ≤0.5 g/10 minutes melt mass flow rate (MFR) (230°C at 2.16 kg) with 5-40 parts by mass of a low-density polyethylene having ≥500% elongation at break and ≤0.25 g/10 minutes MFR (190°C at 2.16 Kg), 80-120 parts by mass of a metal hydroxide treated with a silicone and ≥0.1 part by mass of a rat poison and is crosslinked by electron beam irradiation. Consequently, the anti-rat, abrasion-resistant and flame-retardant resin has excellent properties, namely, heat resistance, abrasion resistance, flame retardance and anti-rat property and proper flexibility.;COPYRIGHT: (C)2007,JPO&INPIT
