Description
厚み0.35mmのアルミニウム含量55重量%の溶融アルミニウム−亜鉛めっき鋼板の表面に塗布型クロメート処理をCr量換算で40mg/m2となるように施した。
各実施例及び比較例の塗装鋼板について、エッジ部分にポリエステルテープを貼着してカバーした状態で、JIS K5400(1990)9.8に準拠した試験を行い、このときサンシャインカーボンアーク灯式による光沢保持率及び色相変化の測定を行った。このとき、ブラックパネル温度を83℃として連続照射試験を行い、2000時間経過後の評価を以下の基準により行った。
◎…70%以上。
○…50%以上70%未満。
△…30%以上50%未満。
×…30%未満。
◎…3.0以下。
○…3.0超、6.0以下。
△…6.0超、9.0以下。
×…9.0超。
○…柄模様が明確に視認できる。
△…柄模様が容易に視認できない。
×…柄意匠が消失して視認できない。
各実施例及び比較例の塗装鋼板について、エッジ部分にポリエステルテープを貼着してカバーし、超促進耐候性試験機(岩崎電気製「SUV−F2」)および耐湿試験機(スガ試験機製「CT−3型」)を用い、照射時間24時間、ブラックパネル温度63℃、紫外線強度100mW/cm2の条件でのUV照射試験と、試験時間24時間、槽内温度50℃、槽内湿度98%以上の条件での湿潤試験を1サイクルとする試験サイクルを10サイクル繰り返して行った後の、光沢保持率及び色相変化の測定を行い、下記基準により評価を行った。
◎…70%以上。
○…50%以上70%未満。
△…30%以上50%未満。
×…30%未満。
◎…3.0以下。
○…3.0超、6.0以下。
△…6.0超、9.0以下。
×…9.0超。
各実施例及び比較例の塗装鋼板について、20℃の室温において塗装面を外側として180°折り曲げた後、セロハン粘着テープを折り曲げ部分の表面にあてがい、手指で十分に擦って貼着させた後、これを直ちに引きはがした。この試験を折り曲げ時のT数を変更して行い、折り曲げ部分におけるセロハン粘着テープを引きはがした箇所を目視で観察し、以下のように評価を行った。T数とは、折り曲げ時に折り曲げ部分の内側に挟む塗装鋼板と同じ厚さの板の数である。
◎…0T折り曲げで塗膜の剥離なし。
○…塗膜の剥離が2T以下で発生。
×…塗膜の剥離が3T以下で発生。
各実施例及び比較例の塗装アルミニウム−亜鉛合金めっき鋼板の上塗り被膜の硬度を、JIS K5400(1990)8.4.2に準拠して求めた。
○…素地に至る塗膜の亀裂が3H以上で発生。
△…素地に至る塗膜の亀裂がH以上で発生。
×…素地に至る塗膜の亀裂がF以上で発生。
各実施例及び比較例につき、塗装鋼板を98℃以上の沸騰したイオン交換水中に6時間浸漬した後、23℃のイオン交換水中に18時間浸漬する処理を1サイクルとしてこれを5サイクル施した後、室温で2時間乾燥させ、次いで1mm間隔で10×10=100個の塗膜カット碁盤目を作った。この塗装鋼板をエリクセンにて6mm押出を行ってセロハン粘着テープを塗膜に粘着させ、これを直ちに引きはがし、下記評価基準にて評価した。
◎…クリヤー塗膜の剥離なし。
○…クリヤー塗膜の剥離5%未満。
×…クリヤー塗膜の剥離5%以上又は色相塗膜以下の塗膜の剥離が発生。
各実施例及び比較例につき、横7cm、縦15cmの寸法にカットした塗装鋼板の端縁部をポリエステルテープにてシールし、更にこの塗装鋼板の上下に分割した下側の領域にカッターナイフにて十字に交差する2本のカット傷を形成し、これを試験サンプルとした。この試験サンプルに対してJIS K 5400 9.1に定める試験方法によって塩水噴霧試験を3000時間行い、平面部の塗膜及びカット部について白錆、ブリスターの発生状況を観察し、下記評価基準にて評価した。
◎…上側の領域に異常なし、且つ下側の領域のカット部の錆ふくれが片側5mm以下。
○…上側の領域に異常なし、且つ下側の領域のカット部の錆ふくれが片側10mm以下。
×…上側の領域に錆ふくれ発生。
