摘要
采用铜、钴、镍等金属氢氧化物胶体溶液,作为 ABS 塑料电镀活化处理液时,它们都有不同程度的催化活性,其中以铜-镍组成的混合胶体液的活化效果为最好。当该混合胶体活化液中,NP^(2+)/Cu^(2+)=0.5~1,pH 值为6.0~8.0时,在室温下活化处理 ABS 塑料,并经硼氢化钠还原、化学镀铜、电镀铜加厚等,最终所得试片与贵金属银活化工艺所得试片相比,外观无明显差异。
When ABS plastics are activated with the colloidal sol of Cu,Go,Ni,all the colloidal sol holds activation properties.The best result has been obtainnd usiog the colloidal sol of Cu(OH)_2-Ni(OH)_2.As Ni^(2+)/Cu^(2+)=0.5~1,pH=6~8 and room temerature operated,the similar results have been obtained for electroless plating of copper,el- ectroplating of copper on ABS plastics with those activated by conventional silver method.
