Improvement of adhesion of metal coatings to resinous articles |
摘要 |
<p>A method for metallising a resinous substrate comprising an addn. copolymer(s) comprising structural gps. derived from olefinic nitrile and a conjugated diene, comprises: (1) contacting at least a portion of the surface with aq. tetravalent Ce in a concn. of at least 0.1 M; (2) non-electrolytically depositing a metal layer or the surface; and (3) heat treating the metal-coated surface at 50-80 deg.C for at least 10 mins. Also claimed is an article comprising a resinous substrate that has been metallised by this method. The cerium soln. treatment is conducted at 40-65 deg.C. The metal layer is deposited by electroless deposition. A further metal coating(s) may be deposited on the substrate after the electroless metal deposition, either by electroless deposition or electrolytically. The metal-coated surface is then further heat treated at 50-80 deg.C for at least 30 mins. The substrate comprises an acrylonitrile-butadiene-styrene resin. The cerium is all in soln. in the aq. phase. The soln. has a Ce concn. of 0.15-0.50 M, and pref. further contains HNO3 in a concn. of 8N or less. The metal deposited in the electroless deposition step is Ni or Cu; and the further metal coating is pref. of Cu.</p> |
