Description
本発明者らが、特許文献1に開示された容器用鋼板を用いて、ネック部分に関するフィルム密着性(以下、「高フィルム密着性」ともいう)について検討を行ったところ、昨今求められているレベルには達しておらず、改良が必要であることが分かった。
そこで、本発明は、高フィルム密着性に優れた容器用鋼板を得ることができる容器用鋼板の製造方法を提供することを目的とする。
すなわち、本発明は、以下の(1)〜(6)を提供する。
以下、本発明の容器用鋼板の製造方法について詳細に説明する。
本発明で用いられる鋼板としては、特に限定されず、通常、容器材料として使用される鋼板原板を用いることができる。また、この鋼板原板の製造方法、材質なども特に規制されるものではなく、通常の鋼片製造工程から熱間圧延、酸洗、冷間圧延、焼鈍、調質圧延等の各工程を経て製造されたものを使用することができる。
下地Ni層中の金属Ni量は、耐食性発現の観点および経済的な観点から、5〜150mg/m2であることが好ましい。
下地Ni層として、加熱処理を施して拡散層を形成する場合、加熱処理の前後または加熱処理と同時に、窒化処理を行ってもよい。
化成皮膜は、上述した鋼板上に形成される皮膜であって、金属Zr量1〜100mg/m2、F量0.1mg/m2以下の皮膜である。
特に陰極電解処理においては、処理液中に硝酸イオンとアンモニウムイオンとを共存させることが好ましい。これにより、数秒から数十秒程度の短時間処理が可能となり、また、耐食性や密着性の向上効果に優れた化成皮膜の形成が可能となる。
また、処理液中には、リン酸イオンが含有されていてもよい。
化成皮膜中の金属Zr量が1mg/m2以上であれば、実用上、問題ないレベルの耐食性と密着性が確保される。また、金属Zr量が100mg/m2を超えると、化成皮膜自体の密着性が劣化するとともに電気抵抗が上昇し溶接性が劣化する。したがって、化成皮膜中の金属Zr量は、1〜100mg/m2であり、1〜20mg/m2であるのが好ましく、1〜10mg/m2であるのがより好ましい。
化成皮膜中のF量は、0.1mg/m2を超えると、これらの諸特性の劣化が顕在化し始めることから、0.1mg/m2以下である。
化成皮膜中のF量を0.1mg/m2以下にするためには、化成皮膜を形成した後、温水中での浸漬処理やスプレー処理により洗浄処理を行えばよい。この際、処理温度を高く、または、処理時間を長くすることによりF量を減少させることができる。
例えば、化成皮膜中のF量を0.1mg/m2以下にするには40℃以上の温水で0.5秒以上の浸漬処理あるいはスプレー処理をすればよい。
本発明においては、化成皮膜を形成した後に、化成皮膜が形成された鋼板を、温度80℃以上、より好ましくは温度90℃以上の水で洗浄し、その後、乾燥を行う。このような洗浄を行うことにより得られる容器用鋼板においては、化成皮膜の表面が適度に粗面化され、高フィルム密着性が良好になるものと考えられる。
また、このような洗浄を行うことにより、化成皮膜中に存するFを除去してF量を減少させる点でも効果が見られる。
なお、浸漬の場合、浸漬時間は、特に限定されないが、1秒以上であるのが好ましい。
また、乾燥の温度は、特に限定されないが、70℃以上であるのが好ましい。
以下の処理法(1−0)〜(1−7)の方法を用いて、板厚0.17〜0.23mmの鋼板上に表面処理層を形成した。
(1−0)冷間圧延後、焼鈍、調圧された原板に脱脂、酸洗を施した鋼板を作製した。
(1−1)冷間圧延後、焼鈍、調圧された原板を脱脂、酸洗後、硫酸−塩酸浴を用いてSn−Ni合金めっきを施し、Ni、Snめっき鋼板を作製した。
(1−2)冷間圧延後、焼鈍、調圧された原板を脱脂、酸洗後、ワット浴を用いてNiめっきを施し、Niめっき鋼板を作製した。
(1−3)冷間圧延後、ワット浴を用いてNiめっきを施し、焼鈍時にNi拡散層を形成させ、Niめっき鋼板を作製した。
(1−4)冷間圧延後、焼鈍、調圧された原板を脱脂、酸洗後、フェロスタン浴を用いてSnをめっきし、Snめっき鋼板を作製した。
(1−5)冷間圧延後、焼鈍、調圧された原板を脱脂、酸洗後、フェロスタン浴を用いてSnをめっきし、その後、溶融溶錫処理(リフロー処理)を行い、Sn合金層を有するSnめっき鋼板を作製した。
(1−6)冷間圧延後、原板を脱脂、酸洗後、ワット浴を用いてNiめっきを施し、焼鈍時にNi拡散層を形成させ、脱脂、酸洗後、フェロスタン浴を用いてSnめっきを施し、その後、溶融溶錫処理を行い、Sn合金層を有するNi、Snめっき鋼板を作製した。
(1−7)冷間圧延後、焼鈍、調圧された原板を脱脂、酸洗後、硫酸−塩酸浴を用いてFe−Ni合金めっきを施し、引き続き、フェロスタン浴を用いてSnめっきを施し、その後、溶融溶錫処理(リフロー処理)を行い、Sn合金層を有するNi、Snめっき鋼板を作製した。
なお、(1−6)および(1−7)の処理を行った場合に、光学顕微鏡にて表面を観察し、島状Sn状況を評価したところ、全体的に島が形成されていることが確認された。
上記の処理により表面処理層を形成した後、以下の処理法(2−1)〜(2−3)で化成皮膜を形成した。
(2−1)K2ZrF6(4.3g/L)を溶解させて硝酸アンモニウムを添加してpHを2.65に調整した処理液に、上記鋼板を浸漬し、浴温30℃で、第1表に示す条件で陰極電解して化成皮膜を形成した。
(2−2)K2ZrF6(4.3g/L)とリン酸(1.2g/L)を溶解させて硝酸アンモニウムを添加してpHを2.65に調整した処理液に、上記鋼板を浸漬し、浴温30℃で、第1表に示す条件で陰極電解して化成皮膜を形成した。
(2−3)K2ZrF6(4.3g/L)とリン酸ナトリウム(1.4g/L)とフェノール樹脂(0.7g/L)を溶解させてリン酸を添加してpHを2.65に調整した処理液に、上記鋼板を浸漬し、浴温30℃で、第1表に示す条件で陰極電解して化成皮膜を形成した。
なお、フェノール樹脂としては、上述した、N,N−ジエタノールアミン変性した水溶性フェノール樹脂(重量平均分子量:5000)を使用した。
上記の処理により化成皮膜を形成した後、以下の処理法(3−1)〜(3−3)で洗浄を行った。
(3−1)75℃の水に2秒間浸漬した後、75℃で乾燥した。
(3−2)80℃の水に2秒間浸漬した後、75℃で乾燥した。
(3−3)95℃の水に2秒間浸漬した後、75℃で乾燥した。

まず、実施例、参考例及び比較例の各試験材の両面に、厚さが20μmのPETフィルムを200℃でラミネートした後、絞りしごき加工を行って缶体を作製し、作製した缶体にネッキング加工を施してネック部を形成した。この缶体を120℃で30分間のレトルト処理を行い、ネック部におけるフィルムの剥離状況を評価した。
具体的には、剥離が全くなかったものを「◎」、実用上問題がない程度の極僅かな剥離が生じていたものを「○」、部分的に剥離が生じて実用上問題があるものを「△」、大部分で剥離が生じていたものを「×」と評価した。結果を第1表に示す。
これに対して、化成皮膜を形成した後に温度80℃以上の水での洗浄を行った実施例2,11および13ならびに参考例1,3〜10および12は、いずれも高フィルム密着性に優れることが分かった。
また、参考例1と実施例2とを対比すると、温度95℃の水で洗浄を行った実施例2は、温度80℃の水で洗浄を行った参考例1よりも高フィルム密着性に優れることが分かった。これは、参考例10および実施例11、ならびに、参考例12および実施例13についても、同様の傾向が見られることが分かった。
