Abstract
【解決手段】本発明のゴム補強用繊維の処理方法は、多価アルコール、3官能以上のブロックポリイソシアネート、及びゴムラテックスを含む前処理剤で処理し、ついでブロックポリイソシアネート及びゴムラテックスを含む後処理剤で処理することを特徴とする。さらには多価アルコールが3官能以上であることや、脂肪族アルコールであることが好ましい。
【選択図】なし
Description
処理コードとゴムとの接着力を示すものである。天然ゴムを主成分とするカーカス配合の未加硫ゴムシート表層近くに7本のコードを埋め、150℃の温度で、30分間、50kg/cm2のプレス圧力(初期値)、又は80℃の温度で40分間、50kg/cm2のプレス圧力(耐熱値)で加硫し、次いで、両端のコードを残し3本のコードをゴムシート面に対し90度の方向へ200mm/分の速度で剥離するのに要した力をN/3本で示したものである。
3官能ブロックポリイソシアネート(明成化学工業製 NBP211)、多価アルコール(ジペンタエリスリトールの6エチレンオキサイド付加物)、VPラテックス、塩化ビニルラテックス(日信化学工業製 ビニブラン609)の固体成分を100:1.5:50:50で混合し、全体の固体成分濃度を10%とし、前処理剤用の処理液(1)とした。
に、170℃の温度で2分間乾燥し、引続いて、240℃の温度で1分間の熱処理を行った。得られたタイヤコードには、処理剤の固形分として、前処理剤が1.0重量%、後処理剤が1.7重量%付着していた。得られた処理コードを天然ゴムを主成分とするカーカス配合の未加硫ゴム中に埋め込み、150℃の温度で30分間、及び180℃の温度で60分間加硫し前記の方法により評価した。その結果を表1に示す。
処理液(1)の3官能ブロックポリイソシアネートの代わりに、4官能ブロックポリイソシアネート(明成化学工業製NBP873)を用い、濃度を調整するため、水の添加量を変化させた処理液(3)を作成し前処理剤とした。
処理液(1)の代わりに処理液(3)を用いた以外は実施例1と同様の処理を行い、その結果を表1に併せて示した。
後処理剤として、熱可塑性エラストマー(第一工業製薬製、F2008D)、ブロックポリイソシアネート(明成化学工業製、DM6011)、VPラテックスを固体成分比で50:15:50で混合し、全体の固体成分濃度を20%とした処理液(4)を作成した。
処理液(2)の代わりに処理液(4)を用い、得られたタイヤコードには、処理剤の固形分として、前処理剤が2.0重量%、後処理剤が2.2重量%付着させた以外は実施例1と同様の処理を行い、その結果を表1に併せて示した。
前処理剤に多価アルコールを用いない以外は、実施例1と同様に処理を行い、その結果を表1に併せて示した。
前処理剤の3官能ブロックポリイソシアネートの代わりに2官能ブロックポリイソシアネート(明成化学工業製、DM6011)を用いた以外は実施例1と同様に行い、その結果を表1に併せて示した。
処理液(1)のVPラテックス及び塩化ビニルラテックスを添加しない処理液(5)を作成した。
前処理剤として処理液(1)の代わりに処理液(5)を用いた以外は実施例1と同様に行い、その結果を表1に併せて示した。
前処理剤に多価アルコールを用いない以外は、実施例3と同様に処理を行い、その結果を表1に併せて示した。
