以下に、本発明を詳細に説明する。
上記亜鉛イオンの供給源としては、亜鉛を含有する化合物であれば特に限定されず、例えば、亜鉛、酸化亜鉛、炭酸亜鉛、硝酸亜鉛等を挙げることができる。
上記リン酸イオンの供給源としては、リン酸を含有する化合物であれば特に限定されず、例えば、リン酸、五酸化リン、リン酸二水素ナトリウム等を挙げることができる。また、リン酸亜鉛処理剤に使用される他の成分を適宜含有してもよい。
上記チオカルボニル基含有化合物の例としては、下記式(III)
上記グアニジル基含有化合物は、単独で用いてもよく、2種以上を併用してもよい。
(亜鉛メッキ鋼板の処理方法)
表1に示したメッキ原板を使用し、アルカリ脱脂処理の後、リン酸亜鉛処理、後処理を順次行い試験板を調整した。
リン酸亜鉛処理は、市販のTiO2コロイド系表面調整処理の後、表2に示すように調製した浴を使用して、スプレー法により、温度45℃で処理時間1〜10秒間で行い、更に、水洗して乾燥した。
後処理は、表3に示す成分を10質量部含有する水性処理剤をロールコーターを用いて塗布した。
表4に示した条件(原板の種類、リン酸亜鉛処理の処理浴、リン酸亜鉛処理皮膜の皮膜量、後処理剤、後処理皮膜の皮膜量)となるように試験板を製造した。原板としては表1中のEG20又はGI70を使用し、リン酸亜鉛処理浴としては表2中のNo.1〜3を使用し(なお、比較例1は、リン酸亜鉛処理を行わなかった。)、後処理剤としては表3中のNo.1〜8を使用した。リン酸亜鉛処理後の皮膜量は、クロム酸でリン酸亜鉛処理皮膜を溶解し、前後の質量差から算出した。リン酸亜鉛処理後のサンプルに、各後処理剤を塗布し、到達板温80℃で乾燥して放置、冷却した。塗布前後の質量差から後処理皮膜の皮膜量を算出した。
耐食性
サンプルのエッジ・裏面をテープシールし、SST(JIS−Z−2371)試験を行った。72Hr後の白錆発生状況を観察した。評価基準は、以下のようにした。
〇;白錆発生なし
△;白錆10%未満
×;白錆10%超
サンプルのエッジ・裏面をテープシールし、市販のアルカリ脱脂液(pH=12.5、40℃、1分浸漬)で脱脂した後、SST(JIS−Z−2371)試験を行った。72Hr後の白錆発生状況を観察した。評価基準は、以下のようにした。
〇;白錆発生なし
△;白錆10%未満
×;白錆10%超
サンプルを市販のアルカリ脱脂液(pH=10.5、40℃、1分浸漬)で脱脂した後、メラミンアルキド塗料(日本ペイント社製、スーパーラック100)を乾燥膜厚が30μmとなるよう塗布し、120℃で25分間焼付けした。一昼夜放置後沸騰水に30分間浸漬し、取り出して1日放置の後、1mm間隔の碁盤目カット疵を入れ、更にエリクセン7mm押し出しを行い、テープでの剥離を行った。評価基準は、以下のようにした。
〇;剥離皆無
△;カット疵周辺で剥離
×;剥離
以上の評価結果を表4に示した。
表5に示した条件(原板の種類、リン酸亜鉛処理の処理浴、リン酸亜鉛処理皮膜の皮膜量、マグネシウム/リン質量比、マグネシウム量、後処理剤、後処理皮膜の皮膜量)となるように試験板を製造した。原板としては表1中のEG30又はGI70を使用し、リン酸亜鉛処理浴としては表2中のNo.3、4を使用し、後処理剤としては表3中のNo.1、3、5、6、7、8を使用した。リン酸亜鉛処理皮膜の皮膜量と組成は、クロム酸でリン酸亜鉛処理皮膜を溶解し、ICP分析により定量、算出した。リン酸亜鉛処理後のサンプルに、各後処理剤を塗布し、到達板温150℃で乾燥して水冷後、乾燥放置した。塗布前後の質量差から後処理皮膜の皮膜量を算出した。
耐食性
サンプルのエッジ・裏面をテープシールし、カッターでクロスカット疵(地鉄に達する疵)を入れ、CCT試験を行った。15サイクル後の赤錆発生状況を観察した。
[CCT試験条件]
塩水噴霧(5%NaCl、35℃)6時間→乾燥(50℃、45%RH)3時間→湿潤(50℃、95%RH)14時間→乾燥(50℃、45%RH)1時間、を1サイクルとした繰り返しを行った。
評価基準は、以下のようにした。
〇;赤錆発生なし
△;疵部付近より赤錆発生
×;全面赤錆発生
サンプルのエッジ・裏面をテープシールし、カッターでクロスカット疵(地鉄に達する疵)を入れ、更に市販のアルカリ脱脂液(pH=12.5、40℃、1分浸漬)で脱脂した後、CCT試験を行った。15サイクル後の赤錆発生状況を観察した。CCT試験条件は、耐食性の評価と同様に行った。評価基準は、以下のようにした。
〇;赤錆発生なし
△;疵部付近より赤錆発生
×;全面赤錆発生
サンプルを市販のアルカリ脱脂液(pH=10.5、40℃、1分浸漬)、自動車用化成処理(日本ペイント社製サーフダイン2500MZL)を施した後、自動車用カチオン電着塗装(日本ペイント社製V20、20μm、170℃、20分焼き付け)を行った。一昼夜放置後、50℃温水に浸漬し、10日後取り出して2mm間隔の碁盤目カット疵を入れ、更にエリクセン7mm押し出しを行い、テープでの剥離を行った。評価基準は、以下のようにした。
〇;剥離皆無
△;カット疵周辺で剥離
×;剥離
以上の評価結果を表5に示した。
