一种水性无铬锌铝涂料及其制备方法
摘要：
本发明公开了一种水性无铬锌铝涂料，它包括使用时予以混合调匀的A剂和B剂，以A剂和B剂的合计重量为100%，A剂包括下列重量百分比的组分：乳化剂：1%-5%，醇：10%-25%，消泡剂：0%-5%，增稠剂：0%-0.3%，金属锌铝粉或者锌铝膏：25%-35%；所述B剂包括下列重量百分比的组分：去离子水：20%-40%，硅烷偶联剂：10%-20%。本发明水性无铬锌铝涂料无六价铬及铅、汞、镉重金属离子化合物，不含苯、二甲苯等有毒有机溶剂，涂层固化温度为250-300℃，20分钟即可，大大地缩短了时间。本发明还提供了该水性无铬锌铝涂料的制备及其涂覆方法。
摘要（英）：

The invention discloses aqueous chromium-free zinc and aluminum coating. The coating comprises an agent A and an agent B, which are mixed and blended uniformly when the coating is used, wherein based on the total weight, which is 100 percent, of the agent A and the agent B, the agent A comprises 1 to 5 weight percent of emulsifier, 10 to 25 weight percent of ethanol, 0 to 5 weight percent of deforming agent, 0 to 0.3 weight percent of thickener and 25 to 35 weight percent of metal zinc aluminum powder or zinc aluminum paste; and the agent B comprises 20 to 40 weight percent of deionized water, and 10 to 20 weight percent of silane coupling agent. The aqueous chromium-free zinc and aluminum coating does not contain hexavalent chromium, lead, mercury and cadmium heavy metal ion compounds or toxic organic solvents such as benzene and dimethylbenzene. The curing temperature of the coating is 250 to 300 DEG C, and the curing time of the coating is 20 minutes which is much shorter. The invention also provides the preparation method and the coating method of the aqueous chromium-free zinc and aluminum coating.
