Abstract
【解決手段】(A)ポリプロピレン単独重合体40質量部以上60質量部以下、(B)ポリプロピレン系変性樹脂1質量部以上30質量部以下、(C)熱可塑性エラストマー10質量部以上25質量部以下、及び、(D)低密度ポリエチレン1質量部以上15質量部以下からなるベース樹脂100質量部に対して、表面処理された金属水酸化物が100質量部以上180質量部以下配合されてなる樹脂組成物。

Description
表2〜表5に組成を示した34種類の樹脂組成物を用いて、線速300m/分以上の電線の押出成形が可能な設備を用いて、ISO6722に規定される0.13sq電線を0.2mmtの肉厚で線速300m/分以上で被覆し、被覆電線を製造した。このとき、口金として孔径が1〜1.5mmのものを用いた。
ISO6722に準拠する。すなわち、上記で作製した被覆電線に、比重1.260±0.005のバッテリー液(硫酸(H2SO4)水溶液)を一滴ずつ、滴同士が互いに接触しないようにして、振りかけた。このような被覆層に硫酸溶液が接触している状態のものを90℃のオーブン内に8時間保持した後に取り出して、再度、上記同様にバッテリー液を振りかけた後、90℃のオーブン内に8時間保持した。このような動作を1サイクルとして、計2サイクル繰り返した後、室温(23℃±5℃)で30分間放置した。次いで、この被覆電線を所定のマンドレルに巻き付けて、巻き付けられた被覆電線の表面を目視観察した。このとき、導体の露出が認められなかったものについて、1kV、1分間の耐電圧試験を行い、導通が起こらなかったものを、耐バッテリー液性が十分であるとして「○」、導体の露出が認められたもの、および、導通が起こったものを耐バッテリー液性が不十分であるとして「×」として、それぞれ評価した。
ISO6722に準拠する。被覆電線を垂直に対して45℃の角度となるようにドラフト内に設置し、ブンゼンバーナーを用意し、その内炎部内に、設置された被覆電線が位置するようにブンゼンバーナーを移動させる。また、接炎部は設置した電線の下端から100mmの位置に当たるようにする。そして、導体の断面積が2.5mm2以下の電線の場合は15秒後に、導体の断面積が2.5mm2以下の電線の場合は30秒後に、試験試料から炎を外す。このとき、絶縁被膜上の炎が70秒以内に消え、かつ、試験試料上部の絶縁体が50mm以上焼けずに残ったとき、難燃性が十分であるとして「○」、70秒以上燃え続けるか、あるいは、焼け残った試験試料上部の絶縁体が50mm未満の場合、難燃性が不十分であるとして「×」として、それぞれ評価した。
ISO6722に準拠する。長さ600mmの被覆電線をサンプルとして使用する。試験に当たり、−40℃±2℃の低温槽を用い、被覆電線サンプル、および、被覆電線の5倍の径のマンドレルを予め低温槽内に置いて十分に冷却する。その後低温槽内で被覆電線をマンドレルに3周以上巻き付けた後、冷却槽から取り出す。室温に戻った後、被覆電線の、巻き付けられた部分を目視で観察した。このとき、導体の露出が認められなかったものについて、1kV、1分間の耐電圧試験を行い、導通が起こらなかったないものを、耐低温性が十分であるとして「○」、導体の露出が認められたもの、および、導通が起こったものを耐低温性が不十分であるとして「×」として、それぞれ評価した。
ISO6722に準拠する。7Nの荷重、直径0.45mmの針金、断面積0,13mm2の芯線、および、厚さ0.2mmの被覆層を有する被覆電線を用いて、スクレープ摩耗規格で測定を実施し、100回以上のスクレープに耐えた場合に、耐摩耗性が十分であるとして「○」、100回未満のスクレープで導通が生じた場合、耐摩耗性が不十分であるとして「×」として、それぞれ評価した。これら評価結果を表2〜5に併せて示した。
