环境友好型水性防锈剂、其制备方法及应用
摘要：
本发明公开了一种环境友好型水性防锈剂、其制备方法及应用。所述防锈剂主要是由环氧化合物与磷酸在有或无溶剂下反应后以醇胺类化合物中和而形成的混合物体系。本发明环境友好型水性防锈剂的最低有效使用浓度可达0.2wt%，使用方法简单，并且防锈时间长，适合中长期防锈，易于清洗，同时还不含亚硝基胺等有毒物质，具有节能减排、安全环保的效果，而且其制备方法简单，原料来源广泛，用量少，成本低，适用于大规模生产。
摘要（英）：

The invention discloses an environment-friendly water-based antirust agent as well as a preparation method and an application thereof. The antirust agent is a mixture system which is formed by neutralizing an epoxy compound and phosphoric acid by using an alcohol amine compound after reaction with or without a solvent. The lowest effective working concentration of the environment-friendly water-based antirust agent can reach 0.2wt%, and the environment-friendly water-based antirust agent is simple in using method, long in antirust time, suitable for rust prevention for medium and long terms and easy to clean. Meanwhile, the environment-friendly water-based antirust agent is free of toxic matters such as nitrosamine, has the effects of saving energy and reducing emission and being safe and environment-friendly and is simple in preparation method, wide in source of raw materials, less in use level, low in cost and suitable for large-scale production.
