Description

一种绿色环保金属防锈剂
技术领域
本发明主要涉及化工技术领域，尤其涉及一种绿色环保金属防锈剂。
背景技术
腐蚀是使金属制品破坏的主要形式之一，据统计，每年由于金属腐蚀所造成的直接经济损失约占国民经济总产值的2%-4%，为避免锈蚀、减少损失，人们采用了各种各样的方法，用防锈剂来保护金属制品，便是目前最常见的防护方法之一。但是传统的防锈油中的钡、铅等对人体有害的物质，在制备和使用过程中会对人体健康产生不利影响，而且传统的防锈油稳定性差，只能进行暂时的防锈，防锈周期短，因此需要一种绿色环保、稳定性好的金属防锈剂。
发明内容

一种绿色环保金属防锈剂，由以下重量份的原料制成：羊毛脂12~14、油酸7~9、羧甲基纤维素钠4~6、聚乙烯醇11~13、六偏磷酸钠8~10、脂肪醇聚氧乙烯醚4~6、氨基磺酸2.3~2.5、乙醇酸2.3~2.5、L-乳酸钠1.7~1.9、水85~90。
所述的水，为去离子水。
一种绿色环保金属防锈剂的制备方法，具体包括以下步骤：
（1）将水加热至50~55℃，加入羧甲基纤维素钠，搅拌均匀，保温40~50分钟，增加防锈剂的稳定性，得羧甲基纤维素钠溶液；
（2）将六偏磷酸钠和脂肪醇聚氧乙烯醚加入羧甲基纤维素钠溶液，混合均匀，加入氨基磺酸和1/2乙醇酸，混合均匀，于60~65℃保温80~90分钟，增强防锈剂的渗透性，去除污渍，增强金属的耐腐蚀性，抑制生锈，得水基；
（3）将聚乙烯醇加热至70~75℃，加入羊毛脂和油酸，保温40~50分钟，搅拌均匀，加入1/2乙醇酸和L-乳酸钠，混合均匀，保温70~80分钟，抑菌杀虫，抗氧化，增加金属的光泽，防止生锈，得醇基；
（4）将醇基加入水基，加热至60~65℃，于280~300转/分钟，搅拌25~30分钟，保温70~80分钟，冷却至室温，得绿色环保金属防锈剂；
（5）真空包装，得成品。
所述绿色环保金属防锈剂的使用方法，取适量绿色环保金属防锈剂，加水稀释至原来的130~150倍，混合均匀，直接擦拭金属表面均可，使用方便。
本发明的优点是：本发明提供的一种绿色环保金属防锈剂，绿色环保，安全健康，具有生物可降解性，在土壤中15个月可自行降解，制备和使用过程中不会损害人体健康，防锈周期达到5.5年，使金属的使用寿命延长10.3%；多种原料属于食品级，安全无毒，使用后的废液不会造成环境污染，能够进行生物降解；L-乳酸钠能够增加防锈剂的耐候性，延长货架期，使经济收入提高12.7%；防锈剂运动粘度小，使用方便，直接进行擦拭即可，能够去除金属表面污渍，增加光泽，抗氧化，防止生锈，延长金属使用寿命。
