[乳化試験、粘度測定]
メトローズSM-400 (2g)を水18gに完全に溶解させた。その溶液にベンジルアルコール80gを投入し、1時間撹拌させ、実施例1の塗膜剥離組成物を調製した。実施例2~11、比較例1~5の塗膜剥離組成物に関しては、表1に記載の割合で同様に調製した。調製後24時間経過後の液状態を目視で確認し、乳化状態を評価した(乳化判定)。評価基準は以下の通りとした。
○:乳白色を維持していた
×:分層した
得られた実施例1~11の剥離組成物の粘度は、B型粘度計を用いて測定した。また、実施例1~11の剥離組成物のpHはpH試験紙を用いて測定した。
乳化試験で調製した剥離組成物を以下の二種類の試験片(塗膜物1、塗膜物2)に塗布し、所定時間経過後、試験片表面をスクレーパーでこすり、塗膜が除去できるかを試験した。評価基準は以下の通りとした。
○:塗膜が除去できた
×:塗膜が除去できなかった
冷間圧延鋼板 (SPCC-SD) 平板 (0.8×25×50mm)に主剤がエポキシ樹脂、硬化剤が変性脂肪族ポリアミンで構成されている塗料 (大日本塗料株式会社製、エポニックスH)を厚さが230μmになるように刷毛で塗布した。その後3日間室温放置し塗膜を硬化させた。得られた塗膜に塗膜剥離組成物を刷毛で塗布した後24時間静置し、塗膜が除去可能かどうか評価した(剥離試験結果(エポキシ系樹脂))。結果を表1~表4に示す。
塗膜物2(フタル酸系):
冷間圧延鋼板 (SPCC-SD) 平板 (0.8×25×50 mm)に長油性フタル酸樹脂塗料 (大日本塗料株式会社製、グリーンズボイド)を厚さ60μmになるように刷毛で塗布した。その後3日間室温で放置し、塗膜を完全に硬化させた。得られた塗膜に塗膜剥離組成物を刷毛で塗布した後、24時間静置し、塗膜が除去可能かどうかを評価した(剥離試験結果(フタル酸系樹脂))。結果を表1~表4に示す。
