Description
レベリング剤の添加によって鋼板表面に対する処理液の展延性が向上するが、シリコーン系のレベリング剤は酸性溶液中で分解し失効する。リン酸塩結晶の間隙をCa,Mg,Mn,Zn等の酸化物や水酸化物で充填することにより耐食性を付与することも知られているが、リン酸塩結晶に比較して酸化物,水酸化物は密着性に劣り、長期の暴露環境で比較すると満足できる耐食性付与とはいえない。
10〜80℃の温度で防錆処理液を下地鋼露出部の鋼板表面に塗布すると、仮に加工油や汚れが付着している鋼板表面であっても十分な展延性を示し、均一な防錆皮膜を形成する。
リン酸エステルの生成反応は、防錆処理液を10℃以上に加温することにより促進される。しかし、80℃を超える高温に加熱すると、リン酸塩と鋼板との反応が急激に進行し処理液中へのFeの溶出や水の蒸発等によって防錆処理液が不安定になる。
溶融めっき鋼板は、溶融亜鉛浴,溶融Zn-Al合金浴,溶融Zn-Al-Mg合金浴,溶融Zn-Mg合金浴,溶融アルミニウム浴又は溶融Al-Si合金浴を用いた連続溶融めっき又はドブ漬けめっきで製造される。溶融めっき後に合金化処理した溶融めっき鋼板も同様に防錆処理できる。
電気めっき鋼板は、電気亜鉛めっき液,電気亜鉛合金めっき液,電気錫めっき液を用いた連続電気めっき法,或いは切板をめっき液に浸漬して個別に電気めっきする方法で製造される。
他方、レベリング剤無添加の処理液では、切断端面,端面近傍の随所に赤錆が検出された。シリコーン系のレベリング剤を添加した防錆処理液Bでは、レベリング剤無添加の処理液よりも多量の赤錆が発生していた。この結果は、酸性溶液中でシリコーン系レベリング剤が分解し失効したことを示唆する。
Claims (2)
- Ca,Mg,Mn,Znから選ばれた一種又は二種以上の金属成分、リン酸イオン、および、一分子中に2個以上のエチレンオキサイド基を有するアセチレングリコールを含み、かつ、リン酸イオンに対するCa,Mg,Mn,Znの合計金属イオン濃度をモル比で1.0以上とする鋼板用防錆処理液。
- 10〜80℃の温度で請求項1に記載の鋼板用防錆処理液を下地鋼露出部の鋼板表面に塗布する防錆処理方法。
