Description

高耐腐蚀性锌带的加工工艺
技术领域
本发明属于锌带加工技术领域，特别涉及高耐腐蚀性锌带的加工工艺。
背景技术
锌带是牺牲阴极保护材料的一种，主要材质是金属锌，腐蚀电池体系正在作用时，接入另一电极丝，该电极的电位较负，这个时候原腐蚀电池就与这个电极就组成了一个新的宏观电。从电化学原理来说，负的电极就是这个新电池的，所谓的阴极便是原腐蚀电池。从电解质向被保护体从体提供一个阴极电流，这时被保护体就会进行阴极保护，就会完成阴极保护。伴随着材料不断消耗不断流出电流，这样就有了牺牲；
而传统的锌带的加工工艺制备出的锌带防腐蚀性不是很理想，为此，我们提出高耐腐蚀性锌带的加工工艺。

S2：将上述去除杂质的不锈钢复合锌带采用火焰烧枪加热，加热温度1000-1205℃，使得整个锌带界面均匀受热，加热后立即采取低温回火，回火温度180-260℃，静置2-4h备用；
S3:将锌带先后经过去离子水、乙醇、5vol％硫酸清洗，然后再用去离子水二次清洗去除残留，最后自然风干；
S4：在容器中加入纯净水，依次加入硅烷偶联剂、KH792硅烷偶联剂、钼酸铵、水溶性纳米硅溶胶、单宁酸粉末，一起搅拌15min，待混合溶液充分溶解均匀后，再加入水溶性苯丙乳液并搅拌20min，最后加入水溶性聚乙烯蜡并搅拌40min以上，至溶液呈均匀稳定相后，密封静置24-48h，制得钝化液；
S5：将上述得到的钝化液通过一次辊涂涂覆到不锈钢复合锌带的表面，并将其置入干燥箱中48-56h，在不锈钢复合锌带表面形成干膜，完成抗腐蚀处理；
S6：将处理好的锌带套上包装膜，放入干燥的室内保存。
