Description

CF2=CF2 ・・・(1)
(化2)
CF2=CF−O−Rf・・・(2)
ただし、Rfは炭素数4以上のパーフルオロアルキル基である。
(化3)
CF2=CF2 ・・・(1)
(化4)
CF2=CF−O−Rf・・・(2)
ただし、Rfは炭素数4以上のパーフルオロアルキル基である。
表1に示す重合比率(質量部)となるように、上記式(1)のモノマー(テトラフルオロエチレン(TFE))と上記式(2)のモノマー(CF2CFORf)とを仕込み、乳化重合によって所定のフッ素樹脂(パーフルオロアルキル化合物)を合成した。側鎖(パーフルオロアルコキシ基)の炭素鎖の構造は、直鎖または分岐鎖として示している。分岐鎖は、側鎖の末端がtert−ブチル基からなるものである。得られたフッ素樹脂と必要に応じて添加されるフィラーとを表1に示す配合組成(質量部)となるように混合することにより、絶縁層用の樹脂組成物を調製した。次いで、押出成形機を用いて、軟銅線を171本撚り合わせた軟銅撚線の導体(断面積15mm2)の外周に絶縁層用の樹脂組成物を1.1mm厚で押出被覆した(350℃)。以上により、実施例1〜10の絶縁電線を得た。
表2に示す重合比率(質量部)となるように各モノマーを仕込んだ以外は実施例と同様にして、比較例1〜7の絶縁電線を得た。
フッ素樹脂(パーフルオロアルキル化合物)として、市販のPFA(三井デュポン製「420HP−J」、側鎖=メトキシ基)を用いた以外は実施例と同様にして、比較例8の絶縁電線を得た。
実施例、比較例の絶縁電線を500mmの長さに切り出して試験片とし、曲げ半径100mmに固定した。次いで、ロードセルで応力を印加し、曲げ半径が50mmになるまで押さえたときの最大荷重を測定した。
社団法人自動車技術規格「JASO D618」に準拠して、ブレード往復法により試験を行った。すなわち、実施例、比較例の絶縁電線を750mmの長さに切り出して試験片とした。そして、23±5℃の室温下で試験片の被覆材(絶縁層)に対し軸方向に10mm以上の長さでブレードを毎分50回の速さで往復させ、導体に接するまでの往復回数を測定した。この際、ブレードにかかる荷重は、7Nとした。回数については1500回以上のものを合格「○」とし、1500回未満のものを不合格「×」とした。また、回数が2000回以上のものは特に優れる「◎」とした。
