摘　　要：黄铜拉链橄榄绿着色清幽淡雅,装饰效果好。采用改进的过硫酸盐体系着色液对黄铜拉链橄榄绿着色工艺进行研究,探讨了各因素对着色效果的影响,并采用扫描电镜(SEM)和能谱成分分析(EDS)方法分析着色层厚度、表面形貌和成分。结果表明,该着色新工艺的最佳条件:25~30 g/LNaOH,30~40 g/L K_(2)S_(2)O_(8),40~50 g/L Na_(2)SO_(4),0.25~1.00 g/L钼酸钠,0.1~0.5 g/L十二烷基硫酸钠,0.05~0.15 g/LPEG 6000;温度30℃,时间60~90 s。在最优工艺条件下所获得的膜层各性能均合格,着色膜均匀,厚度约为1μm,其主要成分为Cu-Zn-Mo-O的复合物。该工艺性能稳定,成本低,装饰效果好,且着色液稳定性好,满足工业生产的要求。Olive green coloring of brass zipper is quiet and elegant,and has a good decorative effect.Chemical olive green coloring was carried out for brass zipper using a improved persulfate coloring bath and the effects of various factors were discussed.The morphology and composition of the olive green plating were investigated by the SEM and EDS techniques.Results indicate that the solution for olive green coloring of brass zipper has an optimal composition of 25‒30 g/L NaOH,30‒40 g/L K_(2)S_(2)O_(8),40‒50 g/L Na_(2)SO_(4),0.25‒1.00 g/L Na_(2)MoO_(4),0.1‒0.5g/L C1_(2)H_(25)SO_(4)Na,0.05‒0.15 g/L PEG 6000,and the optimal coloring temperature and time are 30°C and 60~90s.The comprehensive properties of the colored film obtained under the optimal process conditions are qualified.The colored film is uniform,with a thickness of about 1μm,and its main component is a composite of Cu-Zn-Mo-O.The as-estab‐lished process is simple and cost-effective,and also has good decorative effect and stability,meeting the needs of industry.
