Abstract
【解決手段】処理装置1が、処理槽2と、循環ポンプ5を備えた配管4から連続するダイヤモンド電極を備えた電解セル6と、この電解セル6から処理槽2に供給する配管7とを有し、処理槽2及び電解セル6には85〜98重量%の濃度の硫酸が充填されていて、電解セル6に電流を通電して、硫酸を電気分解することにより過硫酸溶液Sを生成して、この過硫酸溶液Sを配管7を経由して処理槽2に供給し、そして、処理槽2内には、被処理対象であるポリプロピレン樹脂板8が治具8Aに固定された状態で上下方向に吊設されていて、濃度が3g/L以上である過硫酸溶液Sによりポリプロピレン樹脂板8を100〜130℃で処理するポリプロピレン樹脂の親水化処理方法。
【選択図】図1
Description
まず、ヨウ素滴定により処理液(過硫酸溶液S)中に含まれる全酸化剤濃度を測定する。このヨウ素滴定とは、過硫酸溶液Sにヨウ化カリウム(KI)を加えてヨウ素(I2)を遊離させ、そのI2をチオ硫酸ナトリウム標準溶液で滴定してI2の量を求め、そのI2の量から酸化剤濃度を求めるものである。次に、過硫酸溶液Sの過酸化水素濃度のみを過マンガン酸カリウム滴定により求め、ヨウ素滴定値から過マンガン酸カリウム滴定値を差し引くことにより過硫酸濃度を算出した。
過硫酸溶液Sにより親水化処理されたポリプロピレン樹脂板8に対し、下記表1に示す流れでめっき処理を施し、密着性試験用サンプルにとした。
図1に示す装置を用いて、ポリプロピレン樹脂板8の表面処理を行った。処理槽の仕様及び条件は次の通りである。
処理槽2の容積:40L
ポリプロピレン樹脂板8の大きさ:500mm×500mm×厚さ5mm
<過硫酸生成用電解セル6及び電解条件>
セル容積:0.5L
陽極及び陰極:ダイヤモンド電極(直径150mm)
バイポーラ電極材質:陽極、陰極と同じ
電流密度:50A/dm2
液循環量:52L/hr
<親水化処理条件>
硫酸濃度:92重量%
過硫酸濃度:10g/L
処理温度:120℃
処理時間:60分
電解硫酸処理条件を表2に示すように種々設定を変更した以外は実施例1と同様にしてクロムめっきを施し、めっきの密着性を評価した。結果を親水化処理条件とともに表2にあわせて示す。
過硫酸溶液の代わりに、硫酸濃度92重量%の硫酸溶液を用いた以外は実施例1と同様にしてクロムめっきを施し、めっきの密着性を評価した。結果を処理条件とともに表2にあわせて示す。
