Abstract
一种可覆层除锈防锈液，由下列重量份的原料制成：五氯酚钠1‑2、苯甲酸钠1‑2、聚乙烯醇12‑17、聚乙二醇8‑12、癸酸2‑3、N,N‑双(2‑氰乙基)甲酰胺2‑3、异丙醇1‑2、乙氧基化三羟甲基丙烷三丙烯酸酯10‑12、月桂酸钠1‑2、EDTA二钠1‑2、助剂4‑5、水300。本发明使用有机高分子聚合物单体以及螯合剂共同作用，能在金属表面形成薄膜，隔绝空气，防锈物质黏附在薄膜上，有效地防止了金属腐蚀；本发明含有机溶剂，能有效去油、去污，同时含有除锈物质，还能使表面钝化，因此在涂覆本防锈液时,不必经过去油、去锈、清洗、干燥等繁琐工艺而直接涂覆。
Description
技术领域
本发明涉及防锈技术领域，尤其涉及一种可覆层除锈防锈液及其制备方法。
背景技术
金属表面防锈是工业生产中的重要课题，传统的防锈液、防锈油有优点也有缺点。普通防锈水中含大量的亚硝酸钠，有致癌性，不利于环保和人身体健康，而采用保湿剂延长防锈水的寿命，又带来沾手、沾灰尘的弊病，且不能长期防锈；一般硬膜防锈油虽然适合长期防锈，成膜也透明美观，但是无色透明的树脂种类较少，不稳定也易氧化变色，还需要有机溶剂溶解，带来易燃易爆的危险也不利于环保和健康；一般的防锈油使用矿物油，难降解，而且用于短期防锈时也会带来除油难的问题。因此，研究综合性能更加优异，针对不同场合研究更加适合的防锈产品是新的方向和趋势。
发明内容
本发明的目的在于提供一种可覆层除锈防锈液及其制备方法，该防锈液具有除锈、去污、防锈效果好的特点。
本发明的技术方案如下：
一种可覆层除锈防锈液，其特征在于由下列重量份的原料制成：五氯酚钠1-2、苯甲酸钠1-2、聚乙烯醇12-17、聚乙二醇8-12、癸酸2-3、N,N-双(2-氰乙基)甲酰胺2-3、异丙醇1-2、乙氧基化三羟甲基丙烷三丙烯酸酯10-12、月桂酸钠1-2、EDTA二钠1-2、助剂4-5、水300。所述的助剂由下列重量份的原料制成：聚氧乙烯山梨糖醇酐单油酸酯2-3、纳米二氧化钛0.1-0.2、三聚磷酸钠1-2、硅酸钠1-2、乌洛托品1-2、对苯二酚1-2、硼砂3-4、尿素2-3、过硫酸铵1-2、桃胶2-3、水20-24；制备方法是将过硫酸铵溶于水后，再加入其它剩余物料，搅拌10-15分钟，加热至70-80℃，搅拌反应1-2小时，即得。
所述可覆层除锈防锈液的制备方法，其特征在于包括以下步骤：将水加热至40-50℃，加入月桂酸钠、癸酸；继续加热到85-90℃，加入聚乙烯醇、聚乙二醇、异丙醇、乙氧基化三羟甲基丙烷三丙烯酸酯、EDTA二钠，搅拌10-15分钟；加入其他剩余成分，继续搅拌10-15分钟，即得。
本发明的有益效果
本发明使用有机高分子聚合物单体以及螯合剂共同作用，能在金属表面形成薄膜，隔绝空气，防锈物质黏附在薄膜上，有效地防止了金属腐蚀；本发明含有机溶剂，能有效去油、去污，同时含有除锈物质，还能使表面钝化，因此在涂覆本防锈液时,不必经过去油、去锈、清洗、干燥等繁琐工艺而直接涂覆。
具体实施方式
一种可覆层除锈防锈液，由下列重量份（公斤）的原料制成：五氯酚钠1.5、苯甲酸钠1.5、聚乙烯醇15、聚乙二醇10、癸酸2.5、N,N-双(2-氰乙基)甲酰胺2-3、异丙醇1.5、乙氧基化三羟甲基丙烷三丙烯酸酯11、月桂酸钠1.5、EDTA二钠1.5、助剂4.5、水300。所述的助剂由下列重量份（公斤）的原料制成：聚氧乙烯山梨糖醇酐单油酸酯3、纳米二氧化钛0.1、三聚磷酸钠1、硅酸钠2、乌洛托品2、对苯二酚1、硼砂3、尿素3、过硫酸铵1、桃胶2、水20；制备方法是将过硫酸铵溶于水后，再加入其它剩余物料，搅拌10-15分钟，加热至70-80℃，搅拌反应1-2小时，即得。
所述可覆层除锈防锈液的制备方法，包括以下步骤：将水加热至45℃，加入月桂酸钠、癸酸；继续加热到88℃，加入聚乙烯醇、聚乙二醇、异丙醇、乙氧基化三羟甲基丙烷三丙烯酸酯、EDTA二钠，搅拌13分钟；加入其他剩余成分，继续搅拌13分钟，即得。
该实施例得到的可覆层除锈防锈液按国家标准检测，湿热试验*(1)合格；盐水浸渍试验*(1)：合格；腐蚀试验*(2)：合格；除膜性（次）＜6。将所制备的可覆层除锈防锈液刷涂在新加工成的、且没有油污的钢板基体表面，置于室内20天未见明显锈痕。
