Description

一种环保型脱水防锈油的制备方法
技术领域
本发明涉及环保型脱水防锈油的制备方法。
背景技术
在金属加工处理过程中，对于清洗、干燥后的产品进行防锈油处理，防锈油的性能直接影响处理后金属产品的使用寿命、耐腐蚀性等。防锈油主要以润滑油或矿物油作为基础油，通过增加改性剂使防锈油具有不同的功能。CN103290416A公开了一种脱水防锈油，该防锈油主要由石油磺酸钡、二壬基萘磺酸钡、苯骈三氮唑、邻苯二甲酸二丁脂、十二烯基丁二酸、聚异丁烯、变压器油、航空煤油组成，其具有快速脱水、置换金属零件表面水膜的优点。CN103992852A公开了一种气相防锈油，主要由50号机械油、苯甲酸钠、硫磷丁辛基锌盐、聚醚、氧化烷基胺聚、氧乙烯醚、氨基硅油、聚乙二醇、中性二壬基萘磺酸钡、1-羟基苯并三唑、三硼酸钾、成膜助剂组成，该类防锈油对于结构特别复杂，尤其是对具有细小孔隙的零件、细缝处具有很好的缓释效果。上述防锈油虽然防锈效果较好，但均存在原料不环保的缺陷。目前市场上的大多数防锈油都使用含钡的缓蚀剂，钡是重金属，对环境、土壤、人体健康有影响。目前，欧美国家对含钡物品均颁布法规，严禁使用。因此为了保护环境，开发无钡防锈油，成为本领域的研究热点。
发明内容
为解决现有技术中脱水防锈油主要以钡盐为基础，其脱水性能和长期封存防锈性能不能较好的平衡满足，大部分仅能作脱水、工序间防锈使用，或脱水效果不理想，不能满足现代工业要求快速脱水和长期封存防锈的要求。本发明提供一种环保型脱水防锈油的制备方法，该防锈油组成成分绿色环保、具有脱水快、防锈效果好、使用寿命长，提高产品质量的优点。
本发明采用以下技术方案，
所述的环保型脱水防锈油制备方法包括以下步骤：
S1.将矿物油加入反应釜中，加热至60-80℃，在搅拌状态下依次加入石油磺酸钙、硬脂酸铝、油酸三乙醇胺、邻苯二甲酸二丁酯和辛酸二环己胺，转速1000-1200r/min，上述原料共混1-2小时；
S2.向反应釜中加入缓蚀剂，反应2-3小时后，再加入丙酮，升温至65-85℃，搅拌反应3-4小时；
S3.向步骤S2所得中间产物中加入二叔丁基对甲酚搅拌反应2-3小时后，过滤，得脱水防锈油。
环保型脱水防锈油包括以下重量份数的原料：
优选的，所述环保型脱水防锈油包括以下重量份数的原料：
优选的，缓蚀剂由聚天冬氨酸和钨酸钠组成，质量比为(0.9-1.5)：1。更优选0.9:1。
本发明的脱水防锈油不采用含钡的缓蚀剂，以聚天冬氨酸和钨酸钠协同作用，兼具除垢及缓蚀的效果，石油磺酸钙、硬脂酸铝、油酸三乙醇胺、邻苯二甲酸二丁酯和辛酸二环己胺组成复合防锈剂，使本发明生产的防锈油不易变色，以二叔丁基对甲酚作为抗氧剂，使其不易氧化，不影响工件的外观，综合性能优异，具有高的耐盐雾性、耐湿热性、耐老化性等，可清洗性能、脱水性能好，提高了对金属保持的保护作用。本发明脱水防锈剂的制备方法简单、绿色环保、适用于规模化使用。
具体实施方式
下面通过具体实施例详述本发明，但不限制本发明的保护范围。如无特殊说明，本发明所采用的实验方法均为常规方法，所用实验器材、材料、试剂等均可市售获得。
实施例1
本实施例各原料组成为：
S1.将矿物油加入反应釜中，加热至75℃，在搅拌状态下依次加入石油磺酸钙、硬脂酸铝、油酸三乙醇胺、邻苯二甲酸二丁酯和辛酸二环己胺，转速1200r/min，上述原料共混2小时；
S2.向反应釜中加入聚天冬氨酸和钨酸钠，反应3小时后，再加入丙酮，升温至80℃，搅拌反应4小时；
S3.向步骤S2所得中间产物中加入二叔丁基对甲酚搅拌反应2小时后，过滤，得脱水防锈油。
实施例2
本实施例各原料组成为：
S1.将矿物油加入反应釜中，加热至60℃，在搅拌状态下依次加入石油磺酸钙、硬脂酸铝、油酸三乙醇胺、邻苯二甲酸二丁酯和辛酸二环己胺，转速1200r/min，上述原料共混2小时；
S2.向反应釜中加入聚天冬氨酸和钨酸钠，反应2小时后，再加入丙酮，升温至65℃，搅拌反应3小时；
