上記に示す各材料を、後記の表1〜2に示す割合で配合した後、これらを、バンバリーミキサーを用いて混練して、ゴム層用材料を調製した。なお、その未加硫粘度も、同表に示した(測定基準は後記に示す)。そして、このゴム層用材料を20m/分のペースで押出成形した後、この表面に、編組機を用いて、補強糸(アラミド糸)をスパイラル状に巻き付けて補強糸層を形成した。ついで、この補強糸層の外周面に、上記ゴム層用材料を20m/分のペースで押出成形した。このようにして得られたホース状積層体(未加硫)を、屈曲したマンドレルに挿入し、160℃×60分間スチーム加硫させ、その後、マンドレルから抜き取ることにより、最内層(厚み2mm)の外周面に補強糸層が一体形成され、さらにこの補強糸層の外周面に外層(厚み2mm)が一体形成されてなるオイルホース(曲がり管、内径:10mm)を作製した。
JIS K6300の未加硫ゴム物性試験方法のムーニー粘度試験に準じて、測定温度125℃におけるムーニー粘度ML1+4 を測定した。
ゴム層用材料組成物を、プレス成形により160℃×60分間加熱して、厚み2mmのシートを作製し、さらに150℃に8時間放置して二次架橋した後、JIS 5号ダンベル試験片を用いて打ち抜き、これを用いてJIS K6251に準じ、引張速度500mm/分の条件で、加硫物の引張強さ(TB)および伸び(EB)を評価した。
ホースの最内層表面(内周面)の状態を目視し、発泡痕の有無を評価した。すなわち、発泡痕が全くみられないものを○、発泡痕がみられるものを×と評価した。
ホースの最内層および外層のゴム焼け状態を、目視により評価した。すなわち、ゴム焼けが全くみられないものを○と評価し、ゴム焼けがみられるものを×と評価した。
各ホースを、その製造直後に、ストレート径11mmでJASO M101に準拠したバルジ形状のアルミニウム鋳造品パイプに組み付けた。そして、JASO F207に準拠したウォームギアクランプで、3N・mの締付トルクにて締めつけた。つぎに、そのホース内に水を充填し、加圧して、この加圧をホースが破裂するまで続けた。そして、ホースの破裂に至るまでの最高圧力(MPa)を測定した。
