Description
技术领域
本发明涉及一种耐盐雾金属钝化剂及其制备方法。
背景技术
将钢铁、钢材、铸件等经除锈或除油后的金属件经水洗后浸泡在钝化液中直接做钝化处理，可在短时间内在金属表面迅速形成一道致密的钝化保护膜，有效的防止钢铁产品氧化生锈。钝化剂可完全代替钢铁件磷化和或表调处理。具有良好的防锈效果同时，能更好增强油漆涂层与钢铁表面附着力。
申请号为CN201410766852.1 的中国专利申请公开了一种镀锡层钝化剂，其原料按重量份包括：磷酸三钠50-70份，酒石酸钠2-5份，钼酸钠2-5份，柠檬酸钠2-5份，硫酸钴5-10份，植酸15-25份，草酸5-10份，十八胺10-20份，壬基酚聚氧乙烯醚2-5份，吐温-204-7份，三乙醇胺5-10份，2，6-二叔丁基对甲酚2-6份，N,N'-二仲丁基对苯二胺1-3份。本发明提出的镀锡层钝化剂，不含高价铬，不会产生环境污染，不会对人体产生危害，而且耐蚀、耐氧化性能优秀。但是本发明的耐盐雾 性能一般。
发明内容
本发明针对现有技术的不足，提供了一种耐盐雾金属钝化剂及其制备方法，具有良好的耐盐雾性能。
本发明采用以下技术方案：
耐盐雾金属钝化剂，包括以下重量份计的原料：高锰酸钾100～120份、三氧化二锑120～130份、乙二胺10～50份、氟钛酸60～120份、钨酸盐50～60份、硫酸亚铁50～80份、硫酸氢钠10～20份、烷基苯磺酸钠50～100份、醋酸铵100～200份、柠檬酸钠120～150份、柠檬酸钾180～200份、草酸10～60份、偏硼酸钡20～80份、苯甲酸60～80份。
作为优选，耐盐雾金属钝化剂，包括以下重量份计的原料：高锰酸钾110份、三氧化二锑125份、乙二胺30份、氟钛酸100份、钨酸盐55份、硫酸亚铁60份、硫酸氢钠15份、烷基苯磺酸钠80份、醋酸铵150份、柠檬酸钠130份、柠檬酸钾190份、草酸40份、偏硼酸钡50份、苯甲酸70份。
作为优选，耐盐雾金属钝化剂，包括以下重量份计的原料：高锰酸钾100份、三氧化二锑120份、乙二胺10份、氟钛酸60份、钨酸盐50份、硫酸亚铁50份、硫酸氢钠10份、烷基苯磺酸钠50份、醋酸铵100份、柠檬酸钠120份、柠檬酸钾180份、草酸10份、偏硼酸钡20份、苯甲酸60份。
作为优选，耐盐雾金属钝化剂，包括以下重量份计的原料：高锰酸钾120份、三氧化二锑130份、乙二胺50份、氟钛酸120份、钨酸盐60份、硫酸亚铁80份、硫酸氢钠20份、烷基苯磺酸钠100份、醋酸铵200份、柠檬酸钠150份、柠檬酸钾200份、草酸60份、偏硼酸钡80份、苯甲酸80份。
上述耐盐雾金属钝化剂的制备方法，包括以下步骤：将高锰酸钾、三氧化二锑、乙二胺、氟钛酸、钨酸盐、硫酸亚铁、硫酸氢钠、烷基苯磺酸钠混合，搅拌升温至30～40℃，加入醋酸铵、柠檬酸钠、柠檬酸钾、草酸、偏硼酸钡、苯甲酸，并于80～100℃反应2～3小时，即得。
有益效果
本发明的钝化剂可以明显提高金属的耐盐雾时间，使耐盐雾时间高达416h，因为草酸可以增强钝化剂的耐腐蚀性能，在外界的环境如盐雾的侵蚀下，可以保持良好的钝化性能，因此本发明具有良好的耐盐雾性能。
