- the composites according to Comparative Examples 3 and 4 had insufficient peel strength because the amount of non-volatile components in the paint was too small to form a thick coating film. The peeling position could not be confirmed because the coating film was too thin.
- the composite according to Comparative Example 5 had insufficient adhesion between the metal strip and the coating film because the temperature of the metal strip when applying the paint was too high.
- the temperature during baking of the paint was too low, so that the adhesion between the metal strip and the paint film and the bonding force between the paint film and the molded product were insufficient.
- the composite according to Comparative Example 7 had an insufficient bonding force between the coating film and the molded body because the temperature during baking of the paint was too high.
- the coated metal strip according to Comparative Example 8 had insufficient blocking resistance because the temperature of the coated metal strip during winding was too high.
- the composite according to Comparative Example 9 had insufficient peel strength because the coating film was too thin. The peeling position could not be confirmed because the coating film was too thin.
- the coated metal strips according to Examples 1 to 9 were excellent in blocking resistance, and were excellent in adhesion between the metal strip and the coating film and in bonding force between the coating film and the molded body.
- the peeling position was mostly inside the molded body (internal rupture), but part of the interface rupture occurred between the coating film and the molded body.

Description
[1]金属帯の少なくとも一方の面に熱可塑性樹脂組成物の成形体と接合されうる塗膜が形成されている塗装金属帯の製造方法であって、金属帯を走行させる工程と、走行する前記金属帯の表面温度が60℃以下の状態で、走行する前記金属帯上にポリカーボネートユニット含有ポリウレタン樹脂を含み、かつ5質量%以上の不揮発性分を含む塗料を塗布する工程と、走行する前記金属帯に塗布された前記塗料を80~250℃で焼き付けて、走行する前記金属帯上に膜厚が0.3μm以上の塗膜を形成する工程と、前記塗膜を形成された走行する前記金属帯を表面温度が80℃以下になるまで冷却する工程と、前記塗膜を形成された後に冷却された走行する前記金属帯を巻き取る工程と、を有し、前記塗膜中の樹脂合計質量に対するポリカーボネートユニットの割合は、10~80質量%である、塗装金属帯の製造方法。
[2]前記塗料は、Ti、Zr、V、MoおよびWからなる群から選択される金属の酸化物またはフッ化物、あるいはこれらの組み合わせをさらに含む、[1]に記載の塗装金属帯の製造方法。
[3]前記塗料は、アクリル系樹脂、エポキシ系樹脂、ウレタン系樹脂、ポリオレフィン系樹脂、フェノール系樹脂、ポリエステル系樹脂、これらの共重合体、およびこれらの変性物からなる群から選択される1種または2種以上のポリカーボネートユニット非含有樹脂をさらに含む、[1]または[2]に記載の塗装金属帯の製造方法。
第1工程では、金属帯を準備し、走行させる。たとえば、コイル状に金属帯が巻かれたリールを連続式塗装設備(CCL)に設置する。その後、連続式塗装設備を稼働させて、金属帯を繰り出し、走行させる。金属帯を走行させる距離および速度は、特に限定されず、後述する各工程に応じて適宜設定されうる。金属帯は、後述する第4工程において、連続式塗装設備により、再びコイル状に巻き取られる。
金属帯は、その幅に対して長さが長く、コイル状に巻き取ることができる塗装基材である。金属帯の種類は、特に限定されない。金属帯の例には、冷延鋼帯や亜鉛めっき鋼帯、Zn-Al合金めっき鋼帯、Zn-Al-Mg合金めっき鋼帯、Zn-Al-Mg-Si合金めっき鋼帯、アルミニウムめっき鋼帯、ステンレス鋼帯(オーステナイト系、マルテンサイト系、フェライト系、フェライト・マルテンサイト二相系を含む)、アルミニウム帯、アルミニウム合金帯、銅帯、銅合金帯などが含まれる。
なお、第2工程に進む前に金属帯に前処理を施してもよい。たとえば、前処理として金属帯に対して脱脂や酸洗などを行ってもよい。これらの前処理は、金属帯の金属種に応じて、公知の適切な方法で行えばよい。たとえば、アルカリ性処理液の噴霧、アルカリ性処理液への浸漬または電解処理を走行する金属帯に施すことにより脱脂をすることができる。
また、第2工程に進む前に、走行する金属帯の表面に化成処理液を塗布し、乾燥させることで金属帯の上に化成処理皮膜を形成してもよい。化成処理皮膜は、金属帯の表面に配置されており、金属帯と塗膜との間の密着性および金属帯の耐食性を向上させる。
第2工程では、走行する金属帯の上に、所定の条件で所定の塗料を塗布する。
塗料は、必須成分としてポリカーボネートユニット含有ポリウレタン樹脂を含み、任意成分としてポリカーボネートユニット非含有樹脂を含んでいてもよい。また、塗料は、必要に応じて、後述する金属化合物や添加剤などをさらに含んでいてもよい。さらに、塗料は、必要に応じて溶媒を含んでいてもよい。溶媒の種類は、塗料中の各種成分を均一に溶解または分散させうる液体であり、塗膜の形成工程で蒸発する液体であれば特に限定されない。好ましくは、溶媒は水であり、このとき塗料は水系エマルジョンである。
本発明に係る塗装金属帯の製造方法は、走行する金属帯の表面温度が60℃以下の状態で塗料を塗布することを一つの特徴とする。金属帯の表面温度が60℃超の状態で塗料を金属帯に塗布した場合、金属帯の上に塗布された塗料が急速に固化するため、密着性のよい、正常な塗膜を形成することができなくなる。金属帯の表面温度を60℃以下にする方法は、特に限定されない。たとえば、水冷や放冷、空冷などにより金属帯の表面温度が60℃以下になるまで金属帯を冷却すればよい。走行ラインの長さや金属帯の走行速度などは、適宜調整される。上記の観点から、塗料を塗布されるときの金属帯の表面温度は、60℃以下であることが好ましく、40℃以下であることがより好ましい。
第3工程では、第2工程で塗布された塗料を焼き付けて、走行する金属帯に塗膜を形成する。
第4工程では、塗膜が形成された金属帯(塗装金属帯)を冷却し、コイル状に巻き取る。
(1)金属帯の準備
塗装金属帯の塗装基材として、ステンレス鋼帯、溶融Zn-Al-Mg合金めっき鋼帯の2種類の金属帯を準備した。
ステンレス鋼帯として、厚み0.8mm、No.4仕上げのSUS430からなる鋼帯を準備した。
溶融Zn-Al-Mg合金めっき鋼帯として、片面当りのめっき付着量が45g/m2の溶融Zn-6質量%Al-3質量%Mg合金めっき鋼帯を準備した。基材鋼帯は、厚みが0.8mmの冷間圧延鋼帯(SPCC)である。
ポリカーボネートユニット含有樹脂、ポリカーボネートユニット非含有樹脂および各種添加剤を水に添加して、不揮発成分が4~60%の各種塗料を調製した。塗料には、エッチング剤として0.5質量%のフッ化アンモニウム(森田化学工業株式会社)と、無機化合物として2質量%のコロダイルシリカ(日産化学工業株式会社)および0.5質量%のリン酸(キシダ化学株式会社)とをそれぞれ配合した。
以後の各工程は、連続式塗装設備により金属帯を走行させた状態で行った。各金属帯を液温60℃、pH12のアルカリ脱脂水溶液(SD-270;日本ペイント株式会社)に30秒間浸漬して脱脂した。次いで、脱脂された金属帯をスプレー水洗帯に通して、金属帯の表面のアルカリ成分を除去した。次いで、洗浄された金属帯を熱風ドライヤ帯に通して、金属帯を乾燥させた後、必要に応じて放冷し、金属帯の表面温度を30~70℃の範囲内の所定の温度とした。
(1)耐ブロッキング性の評価
コイル状に巻き取られた各塗装金属帯をリコイリングラインに通し、毎分当り100mのラインスピードで巻き直しを行った。このときの、互いに隣接する塗装金属帯間の癒着状態に基づいて、各塗装金属帯の耐ブロッキング性を評価した。各塗装金属帯について、癒着が認められない場合を「○」、癒着が認められる場合を「×」と評価した。
各塗装金属帯について、熱可塑性樹脂組成物の成形体との複合体を作製し、この複合体を用いて塗膜密着性および熱可塑性樹脂組成物の成形体との接合性を評価した。
各塗装金属帯について、区分、塗装金属帯No.、耐ブロッキング性の評価結果、剥離強度の評価結果および剥離位置を表2に示す。
