Abstract

本发明涉及了一种镀锌三价铬彩色钝化剂的制备，采用CrCl3、Na3C6H5O7、NaNO3、CoCl2、AgNO3等物品通过一定的比例溶解混合均匀而成，其能显著提高镀层的耐蚀性能，同时赋予镀层鲜艳的色泽。

Description

一种镀锌三价铬彩色钝化剂的制备 
技术领域
本发明涉及一种镀锌三价铬彩色钝化剂的制备，尤其涉及一种镀锌三价铬彩色钝化剂的成分、各成分的作用及配制方法。 
背景技术
根据GB-2008《电镀污染物排放标准》，对Pd、Hg、Cd、Cr6+、聚溴二苯醚和聚溴联苯等6种第一类污染物的排放标准有了更低的限制。很多国家投入市场的电子电器产品严格要求不能含有以上6种有害物质。所以，环保型的产品替代六价铬钝化成为迫切要求。 
环保型的钝化主要采用三价铬和无铬钝化两个方向。无铬钝化体系有钛酸盐、钼酸盐、钨酸盐、稀土、硅酸盐，目前这些无铬体系虽然无毒环保，但耐蚀性和外观没有六价铬钝化的好，满足不了普通五金件电镀要求，更不用说满足高耐蚀性能要求，所以无铬钝化的工艺未曾在工业上广泛应用过。因此，无六价铬钝化的技术主要立足于三价铬钝化技术。 
发明内容
本发明为了提高镀锌层耐蚀性，同时使镀液中不含有Cr6+而发明了一种镀锌三价铬彩色钝化剂。 
本发明采用CrCl3、Na3C6H5O7、NaNO3、CoCl2、AgNO3等物质组成镀锌三价铬彩色钝化剂。 
本发明的具体制备方法包括如下顺序的步骤： 
a.将计算量的CrCl3倒入少量水中，搅拌使其充分溶解； 
b.将计算量的Na3C6H5O7缓慢加入，搅拌使其充分溶解； 
c.将计算量的NaNO3倒入，搅拌均匀； 
d.将计算量的CoCl2缓慢加入，迅速搅拌，使其充分溶解； 
e.将计算量的AgNO3缓慢加入，迅速搅拌，静置10分钟，过滤。 
本发明所得一种镀锌三价铬彩色钝化剂，为澄清呈深蓝色的液体。 
实验说明 
本发明通过进行镀锌实验后，在三价铬钝化液中实施钝化处理，经过不同时间的处理后，观察镀层的色泽，并进行中性盐雾试验测定其耐蚀性能。 
具体实施方式
本实施例的具体制备步骤如下： 
a.配制通用的低氰镀锌溶液，并调整PH值，进行电镀。 
b.一定时间后取出试样，在3％的HNO3中出光后进行钝化处理，钝化时间从16s～1min。 
c.观察转化膜层的色泽，并进行中性盐雾试验。镀锌三价铬彩色钝化工艺规范为： 
氯化铬(CrCl3)          8～10g/L 
柠檬酸钠(Na3C6H5O7)    10～15g/L 
硝酸钠(NaNO3)          10～20g/L 
氯化钴(CoCl2)          5～10g/L 
硝酸银(AgNO3)          1～5g/L 
温度                   室温 
钝化时间               16～60s 
注：当有搅拌时，钝化时间可以缩短。
