Description
実施例1〜7
表1に示す成分組成のシリコーンゴム1〜4、PE5%コート水酸化マグネシウム、架橋剤を、バンバリーミキサーを用いて常温で混合した。その後、押出し成形機を用いて、軟銅線を7本撚り合わせた軟銅より線の導体(断面積0.5mm2)の外周に0.2mm厚で押出し被覆して絶縁層を形成した。その後200℃×4時間加熱処理して架橋を完了させて、本実施例1〜7の絶縁電線を得た。得られた絶縁電線の外観を観察して評価した。また絶縁電線の耐寒性試験を行い評価した。その結果を表1に合わせて示す。尚、表1の各成分組成の具体的な組成及び、耐寒性試験方法は、下記の通りである。
・シリコーンゴム1:信越化学社製、931(組成:ジメチルシロキサン)
・シリコーンゴム2:信越化学社製、541(組成:ジメチルシロキサン)
・シリコーンゴム3:東芝社製、2267(組成:ジメチルシロキサン)
・シリコーンゴム4:東芝社製、2277(組成:ジメチルシロキサン)
・PE5%コート水酸化マグネシウム
水酸化マグネシウム:結晶成長法、平均粒径1.0μm
表面処理剤:ポリエチレン(三井化学社製、800P)
表面処理剤の使用量:ポリエチレンと水酸化マグネシウムの合計量の5質量%
・架橋剤:日本油脂社製、パーへキシルD(ジ−t−へキシルパーオキサイド)
JIS C3055に準拠して行った。すなわち作製した絶縁電線を38mmの長さに切断し試験片とした。この試験片を耐寒性試験機に装着し、所定の温度まで冷却し、打撃具で打撃して、試験片の打撃後の状態を観察した。5本の試験片を用いて、5本の試験片が全て割れた温度を耐寒温度とした。
表2に示すように、難燃剤として実施例のPE5%コート水酸化マグネシウムを水酸化アルミニウム(昭和電工社製、ハイジライトH42)に変更した以外は、実施例と同様にして、絶縁電線を得た。得られた絶縁電線について実施例と同様に外観及び耐寒性の評価を行った。その結果を表2に合わせて示す。
