JIS C 2107に準拠して測定した引張り強度である。温度20±2℃、湿度50±5%RHに設定された評価試験室内で測定した。測定結果については以下の様に判断する。
良 :引張り強度が15N/10mm以上
不良:引張り強度が15N/10mm未満
JIS C 2107に準拠して測定した引張り伸び率である。長さ150mm、幅10mmのテープサンプルを、温度20±2℃、湿度50±5%RHに設定された評価試験室内で測定した。測定結果については以下の様に判断する。
良 :引張り伸び率が100%以上
不良:引張り伸び率が100%未満
JIS C 2107に準拠して測定した引張り伸び率である。長さ150mm、幅10mmのテープサンプルを、温度120±2℃に設定されたギアオーブンで168時間加熱後、常温で2時間冷却し、測定した。測定結果については以下の様に判断する。
良 :引張り伸び率が80%以上
不良:引張り伸び率が80%未満
φ10mmの電線束に粘着テープを巻き付け、巻き付け終わりの切断時に端末部分の端末剥がれの有無を目視で以下の様に判定する。
良 :端末部分に端末剥がれの無いもの
不良:端末部分に端末剥がれの有るもの
φ10mmの電線束に粘着テープを巻き付けたサンプルを、温度120±2℃に設定されたギアオーブンで168時間加熱後、常温で2時間冷却し、電線束の真ん中で手にて折り曲げて目視で以下の様に判定する。
良 :粘着テープにヒビ、割れの無いもの
不良:粘着テープにヒビ、割れの有るもの
JIS K 7201に記載の装置を用いて測定した燃焼時間4秒以内に消炎する酸素指数(OI)である。長さ100mm、幅20mmのテープサンプルを上部が燃焼円筒の上端部から100mm以上になるようにとりつける。点火器の炎の長さを15~20mmに調整し、テープサンプルの上部に点火し、燃焼し始めてから消炎までの時間を測定する。テープサンプルの燃焼時間が4秒以下で消炎する最大酸素流量と窒素流量を決定し、次式にて酸素指数を求める。
OI値(%)=(酸素流量(L/min))/(酸素流量(L/min)+窒素流量(L/min))
(1)ポリ塩化ビニル樹脂(大洋塩ビ株式会社製TH-1000、平均重合度1000、)、可塑剤としてトリメリット酸トリ-2-エチルヘキシル(DIC株式会社製TOTM)、三酸化アンチモン(鈴裕化学社製、ファイヤーカットTOP-5)を表1に示す配合にてバンバリーミキサーで均一に分散するように溶融混練したのち、カレンダー成形機により、ロール温度165℃にて150μm厚の基材を作製した。
可塑剤の種類及び配合量及び三酸化アンチモンの配合量を表1~表2に示すように変更した以外は、実施例1と同様にしてサンプルテープを得た。各種特性評価を行った結果は表1~表2に示した。
表1に示すように、ポリ塩化ビニル樹脂100質量部に対し、高沸点可塑剤40~65質量部、三酸化アンチモン5~15質量部を含有する樹脂組成物からなる基材を用いた場合には、粘着テープが優れた機械物性を有し、高温雰囲気下に長時間晒された後のヒビや割れの発生が抑制されることが分かった。また、トリメリット酸エステルを用いた実施例では、加熱前後の引張り伸び率の変化が小さかった。
