Abstract
【解決手段】ラミネート金属板の製造方法であって、プラスチックフィルムとしてフッ素樹脂フィルムが使用され、火炎処理に先行して、金属板の接合面を、900〜1200℃の直火で1秒から5秒火炎処理してその接合面の表面温度が40〜70℃になるように予熱し、しかる後、後続する火炎処理によって、前記金属板の接合面の表面温度が250〜450℃になるように加熱する。

Description
そして、鉄板の樹脂ライニングでは接着に際して接着性向上のための所定の前処理(金属板表面や合成樹脂フィルムの浄化:サンディングや脱脂、洗浄、乾燥、アンカーコート等)を行う必要があり、また、ポリエチレン等のフィルムライニングでは鉄側の前処理、プライマーコートが必要で、フィルム側にもコロナ処理を施したり接着性樹脂を重ねた二層構造フィルムを使用するか、プライマーをフィルムにコートしたりする必要があるのに対し、この火炎処理方法では、こうした手間が不要である点において優れている。
特に、4フッ化エチレン−パーフルオロアルキルビニルエーテル共重合樹脂(PFA)、4フッ化エチレン−6フッ化プロピレン共重合樹脂(FEP)、4フッ化エチレン−テトラフルオロエチレン共重合樹脂(ETFE)のように、1分子単位内に2原子以上のフッ素原子を含むフッ素樹脂フィルムの金属表面への熱融着難しいものであった。
前記プラスチックフィルムとしてフッ素樹脂フィルムが使用され、
前記火炎処理に先行して、前記金属板の接合面を、900〜1200℃の直火で1秒から5秒火炎処理してその接合面の表面温度が40〜70℃になるように予熱し、
しかる後、後続する前記火炎処理によって、前記金属板の接合面の表面温度が250〜450℃になるように加熱する、ことを特徴とする。
このフッ素樹脂フィルムを用いることによって、価格的に安価で、一般的に入手が容易であるという利点がある。
更に、本発明の火炎処理の温度・時間を変更する事でポリエチレン、ポリエチレンテレフタレート、ポリプロピレンは言うに及ばず、他の非接着性フィルムについても適用可能である。
図2に示すプロセスにより、金属板3としての0.3mm厚のTFS鋼板(709mmX917mm)に、予熱工程として第1火炎ノズル4により、900〜1200℃の直火(火炎)を4秒間前記金属板3に照射し、該金属板3の表面温度を約60℃に予熱し、更に該金属板3を予熱直後(約1秒後)、第2火炎ノズル5により1400〜1600℃の直火を4秒間照射し、該金属板3の表面温度を300℃に加熱し、フッ素樹脂フィルム2として、厚さ50μmのETFE(旭硝子製フルオンETFE:エチレン−テトラフルオロエチレン系共重合体)を、ロール6により熱圧着し、図1に示すフッ素樹フィルムのラミネート金属板1を作成した。この熱圧着工程の金属板3及びフッ素樹脂フィルム2の移送速度は、15m/minであった。
尚、図1は、フッ素樹脂フィルム2と金属板3の積層状態を模式で示す図であり、相互のサイズは整合させていない。
JISK5400の塗料一般試験方法に基づき、試験片(実施例1及び実施例2のラミネート金属板)のフッ素樹脂フィルム面側に金属板に達する深さで基盤目(1mmピッチで10×10)をカットした後、更にエリクセン8mm張り出しを行い沸騰水中に3時間浸漬し、テープ剥離試験により密着性を評価した。その評価は剥離数が0の場合◎、1〜5の場合を○、6〜10の場合△、11超の場合を×の記号を用いて現すようにして判定した。
試験片(実施例1及び実施例2のラミネート金属板)のフッ素樹脂フィルム面側を外側にして直角に折り曲げ、折り曲げられた状態でJIS Z2371に準拠して5%食塩水、温度35℃で1000時間の塩水噴霧試験を行い試験後の発錆の有無を確認し評価した。全く異常のない場合を◎、折り曲げ部の一部に錆を生じた場合を○、折り曲げ部の全域に錆を生じた場合を△、平板部に錆を生じた場合を×の記号を用いて現すようにして判定した。
試験片(実施例1及び実施例2のラミネート金属板)のフッ素樹脂フィルム面側を外側にして直角に折り曲げ、試験片が切れるまで繰り返し折り曲げ、フィルムの亀裂・剥離を確認した。その評価は全く異常がない場合を◎、亀裂・剥離が認められる場合を×の記号を用いて現すようにして判定した。
試験片(実施例1及び実施例2のラミネート金属板)を200℃空気中で15分間加熱し、これを20回繰り返した後にフッ素樹脂フィルムの剥離、縮み、変色等の有無を確認し評価した。評価は全く異常のない場合を◎、いずれかの異常が認められた場合を×の記号を用いて現すようにして判定した
試験片(実施例1及び実施例2のラミネート金属板)のフッ素樹脂フィルム面側にヘアトニック、ヘアリッキド、黒色マジックインキ、コーヒー、紅茶、マヨネーズ、ケチャップ、醤油、ソース、わさび、からしのそれぞれを常温で1週間接着させた後にエタノールを湿らせたコットンで拭き取り、付着状態を調査し評価した。その評価は一度の拭き取りで完全に除去でき、試験片が全く汚染されていない場合を◎、汚染はされないが二度以上の拭き取り回数を要する場合を○、汚染される場合を×の記号を用いて現すようにと判定した。
