まず、後述の表1に示す各成分を、シリンダー側面に振動子が設けられた二軸混練機に投入し、周波数20kHz、振幅20μmの超音波を付与して、高分子が流動性を有する好適な温度(例えばポリプロピレンなどでは220℃)で約5分混練し、ペレタイザーにてペレット状に成形して本実施例に係る組成物を得た。次いで、得られた各組成物を、φ50mm押出機により、軟銅線を7本撚り合わせた軟銅撚線の導体(断面積0.5mm2)の外周に0.20mm厚で押出被覆し、本実施例に係る絶縁電線を作製した。
JASO D611−94に準拠し、ブレード往復法により行った。すなわち、絶縁電線を750mmの長さに切り出して試験片とした。次いで、25℃の室温下にて、台上に固定した試験片の被覆材の表面を軸方向に10mmの長さにわたってブレードを往復させ、被覆材の摩耗によってブレードが導体に接触するまでの往復回数を測定した。この際、ブレードにかける荷重は7Nとし、ブレードは毎分50回の速度で往復させた。次いで、試験片を100mm移動させて、時計方向に90°回転させ、上記の測定を繰り返した。この測定を同一試験片について合計3回行い、その最低値を評価値とした。磨耗回数が500回以上を合格とした。
