ポリスチレン系樹脂のクロムフリーめっき前処理方法

摘要

Plating on plastics is useful for manufacturing many plated metal products. When using ABS resin, which is often used for plating, etching pretreatment with chromic acid is conducted. This etchant can dissolve butadiene in ABS, forming rough areas on the surface, which are later filled with metals during plating. The consequent anchor effect produces strong adhesion of the metal to the resin.rnNevertheless, few reports in the literature describe plating on polystyrene resin, which is widely used for home electrical appliances, amusement products, etc.rnThis report describes an investigation of pretreatment using ozone water for plating on polystyrene resin. Results show high adhesiveness achieved from optimized pretreatment conditions. Furthermore, no anchor effect was necessary, as inferred from SEM observation and FT-IR analysis. Treatment using ozone water is applicable as a beneficial pretreatment for plating on polystyrene resin.%基体の表面に金属めっきが施された製品は多数存在する。例えば，基体として樹脂を用いた製品としては，自動車部品，住宅建築，水栓製品，家電製品，回路基板などが挙げられ，我々の生活の中で幅広く使用されている。その樹脂素材としては，ABS，ポリカーボネート，ポリエステル，ポリアミド，ポリイミドなど，さまざまな樹脂が適用されている。
