Description
(1) 化成処理を施した金属板の片面もしくは両面上にCaイオン交換シリカを含むプライマー塗膜層を有し、その上層に、(A)30℃以上47℃以下のガラス転位温度を有する数平均分子量が20000超〜23000以下のポリエステル樹脂、(B)アミノ樹脂、(C)酸性触媒、及び(D)揮発性塩基性物質を必須成分として含み、且つ、(A)の全ポリエステル樹脂の固形分100質量部に対して(B)アミノ樹脂の固形分が10〜30質量部から成り更に顔料の含有量が全樹脂固形分100質量部に対して80質量部以下である塗料組成物を塗布して焼付乾燥して成る塗膜を少なくとも有すること特徴とした耐汚染性と耐溶剤性に優れるプレコート金属板。
1. 塗膜加工性試験
作製したプレコート金属板を、180°折り曲げ加工(密着曲げ加工)し、加工部の塗膜を目視で観察し、塗膜の割れの有無を調べた。なお、180°折り曲げを行う際には、プレコート金属板の表面が曲げの外側となるように折り曲げ、さらに曲げの内側にはプレコート金属板と同じ板厚のスペーサーを2枚挟んだ状態で密着曲げを行った(一般に2T曲げとして知られている)。また、加工部に粘着テープを貼り付け、これを勢い良く剥離したときの塗膜の残存状態を目視にて観察した。
2. マジック汚染性試験
赤マジックインキを作成したプレコート金属板の塗膜表面に塗布して、室温で24時間放置した後に、キシレンにて塗布したマジックインキを拭き取った後の跡残りを評価した。マジック跡が消えて見えない場合を○、マジックが僅かに残っている場合を△、マジック跡が消えていない場合を×と評価した。
3. 耐溶剤性試験
サンプルをトルエンに24時間浸漬し、浸漬後の塗膜膨潤状態を目視観察して評価した。塗膜表面が浸漬前と比較して変化がない場合を○、塗膜表面にミミズ腫れの様な跡残りが僅かにあり塗膜の膨潤が僅かに認められる場合を△、塗膜表面にミミズ腫れの様な跡残りが激しくあり塗膜の膨潤が激しく認められる場合を×と評価した。
4. 耐食性試験
作製したプレコート金属板の塗膜面にカット傷を入れて、JIS K 5400.9.1記載の方法で塩水噴霧試験を実施した。塩水は、試験片のクロスカットを入れた面に噴霧した。試験時間は120時間とした。そして、表面側のカット部からの塗膜膨れ幅を測定し、カット部膨れ幅が片側3mm以下の場合を○、カット部膨れ幅が片側3mm超5mm以下の場合を△、カット部膨れ幅が片側5mm超の場合を×と評価した。
