Description
そこで、本件発明者等は、以下の無電解白金めっき液を採用することで上記課題を達成するに至った。
本件発明の無電解白金めっき液は、水溶性白金化合物と、ホルマリン、グルコース、ギ酸、ギ酸塩からなる群から選択される1種以上の還元剤とを含む水溶液である。
本実施形態の無電解白金めっき液によるめっき方法の一例を以下に説明する。ここでは、被めっき物であるめっき基材として、無電解めっき処理によって、絶縁基材の表面に銅皮膜及びニッケル皮膜を順に形成しためっき基材を用いる場合について説明する。めっき基材は、上記のものに限定されず、従来公知のめっき基材を用いることができる。
本実施形態の無電解白金めっき液は、金属等からなる電子部品、電極材料、ABS樹脂、ポリアミド樹脂、ポリカーボネート樹脂等の合成樹脂、アルミナ、ジルコニア等の導電性を持たないセラミックス等のめっきに好適である。特に、ジルコニア等のセラミックス等からなる酸素センサの電極や、種々の宝飾品等の用途に好適に使用することができる。
まず、電解めっき処理によって銅板上に厚さ3μmのニッケル皮膜を形成した。次に、電解めっき処理によってニッケル皮膜の表面に厚さ0.1μmの白金皮膜(白金電解皮膜)を形成することにより、めっき基材を作成した。
本実施例では、水に、水溶性白金化合物としてジクロロテトラアンミン白金(II)0.005mol/L(白金換算で1.0g/L)と、還元剤としてギ酸ナトリウム0.5mol/Lと、錯化剤としてリンゴ酸0.1mol/Lとを溶解して、無電解白金めっき液を調製した。続いて、pH調整剤として水酸化ナトリウム及び硫酸を用いて、無電解白金めっき液のpH(温度25℃)を7.0に調整した。
得られた無電解白金めっき液を温度70℃に加温し、白金電解皮膜が形成されためっき基材を当該無電解白金めっき液に浸漬して無電解めっき処理を行うことにより、白金電解皮膜の表面に白金皮膜(白金無電解皮膜)を形成した。
本比較例では、還元剤としてギ酸ナトリウムに代えてヒドラジン一水和物0.5mol/Lを用いたこと以外は、実施例2と全く同一にして、無電解白金めっき液を調製し、続いて、pH(温度25℃)を11.0に調製した。次に、得られた無電解白金めっき液を用いて、実施例1と全く同一にして、当該無電解白金めっき液の分解の有無を判定した。表1に結果を示す。
本比較例では、還元剤としてギ酸ナトリウムに代えて水酸化ホウ素ナトリウム0.5mol/Lを用いたこと以外は、実施例2と全く同一にして、無電解白金めっき液を調製し、続いて、pH(温度25℃)を11.0に調製した。次に、得られた無電解白金めっき液を用いて、実施例1と全く同一にして、当該無電解白金めっき液の分解の有無を判定した。表1に結果を示す。
本比較例では、白金化合物としてジクロロテトラアンミン白金(II)に代えてジニトロジアンミン白金(II)0.005mol/L(白金換算で1.0g/L)を用いたこと以外は、比較例1と全く同一にして、無電解白金めっき液を調製し、続いて、pH(温度25℃)を11.0に調製した。次に、得られた無電解白金めっき液を用いて、実施例1と全く同一にして、当該無電解白金めっき液の分解の有無を判定した。表1に結果を示す。
本比較例では、白金化合物としてジクロロテトラアンミン白金(II)に代えてジニトロジアンミン白金(II)0.005mol/L(白金換算で1.0g/L)を用いたこと以外は、比較例2と全く同一にして、無電解白金めっき液を調製し、続いて、pH(温度25℃)を11.0に調製した。次に、得られた無電解白金めっき液を用いて、実施例1と全く同一にして、当該無電解白金めっき液の分解の有無を判定した。表1に結果を示す。
