Abstract
本发明涉及了镀锌板仿金的方法，采用在Q235材料上镀锌、出光、钝化、封闭、浸漆、烘干等工艺流程，其能显著提高镀锌装饰板的耐蚀性，同时使装饰板具有良好的装饰效果。
Description
技术领域
本发明涉及一种应用于镀锌装饰板三价铬仿金的方法，尤其涉及一种三价铬仿金的成分及镀锌装饰板方法。
背景技术
镀锌板三价铬仿金方法仿金颜色为18k，耐蚀性和外观都有很大的提高。常用的仿金镀层目前多以黄铜镀液为基础，为二元合金或三元合金，多采用氰工艺，这种工艺不仅不稳定，而且成本高，污染大，得到的有毒性废液无法处理。镀锌板仿金体系有氯化铬、柠檬酸钠、硝酸钠、氯化钴、硝酸银通过一定比例溶解混合均匀而成的镀锌三价铬彩色钝化剂及水溶性清漆等。它与六价铬钝化相比降低了污染，与无铬钝化相比具有更高的耐蚀性，满足了普通五金件电镀要求，所以镀锌板三价铬仿金在工业上和建筑装饰行业具有广泛的应用前景。
发明内容
本发明为了提高镀锌装饰板的耐蚀性，同时使镀液中不含有Cr6+而发明了一种应用于镀锌板仿金的方法。
本发明以Q235材料为基体光亮镀锌，使镀锌厚度在8um以上，室温下用3%硝酸出光4s。
本发明用氯化铬、柠檬酸钠、硝酸钠、氯化钴、硝酸银通过一定比例溶解混合均匀配制成镀锌三价铬彩色钝化剂，为澄清呈深蓝色的液体，其中包括氯化铬9g/L、柠檬酸钠13g/L、硝酸钠15g/L、氯化钴8 g/L、硝酸银3g/L；钝化剂使用时pH值维持在1~2范围内。
本发明将镀锌板在三价铬彩色钝化液中钝化后，呈现金黄色效果,加入封闭剂，使其具有高防腐性、防变色性和极强的附着力，常温下，在水溶性清漆1体积和清水10体积的配比的浸液里浸泡1分钟，提出后在60℃的烘箱里烘干5分钟或置于阳光下直射晾干。
实验说明
本发明通过镀锌实验后，在三价铬彩色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．以Q235材料为基体光亮镀锌，使镀锌层厚度在8um以上，室温下用3%硝酸出光4s；
b.采用氯化铬、柠檬酸钠、硝酸钠、氯化钴、硝酸银通过一定比例溶解混合均匀而成的镀锌三价铬彩色钝化剂；
c.将镀锌装饰板在三价铬铬彩色钝化液中钝化30s,呈现金黄色效果；
d.将钝化后的镀锌装饰板迅速浸入封闭剂，在pH为6.5的条件下浸泡5秒钟；
e.迅速将镀锌装饰板直接浸入水溶性清漆1体积和清水10体积的配比的浸液里浸泡1分钟;
f.提出后在60℃下烘干5分钟或置于阳光下直射晾干。
一种应用于镀锌板仿金的方法规范为：氯化铬、柠檬酸钠、硝酸钠、氯化钴、硝酸银、水溶性清漆。
氯化铬 8~10g/L
柠檬酸钠 10~15g/L
硝酸钠 10~20g/L
氯化钴 5~10g/L
硝酸银 1~5g/L
钝化时间 16~60s
pH 1~2
水溶性清漆 1:10
烘干温度 60℃
注：当有搅拌时，钝化时间可以缩短。
