Flexible waterborne epoxy curing agent as well as preparation method and application thereof

The invention provides an anionic/nonionic waterborne epoxy curing agent as well as a preparation method and application thereof. The waterborne epoxy curing agent comprises the following raw materials: 1 part of epoxy resin; 0.65 to 6 parts of a polyamine compound; 0.1-1 part of an anionic/nonionic emulsifier; and 0.25 to 1.25 parts of a single epoxy reactive diluent. The anionic/nonionic waterborne epoxy curing agent disclosed by the invention is controllable in reaction activity, good in hydrophilicity, good in water dispersion performance, capable of being dispersed or dissolved in water and relatively good in stability and construction performance, and a paint film prepared by matching the anionic/nonionic waterborne epoxy curing agent with an epoxy resin emulsion has excellent impact resistance, flexibility, salt fog resistance and strong adhesive force. 本发明提供一种阴/非离子水性环氧固化剂及其制备方法和应用。水性环氧固化剂的原料包括：环氧树脂1份；多元胺化合物0.65-6份；阴/非离子乳化剂0.1-1份；单环氧活性稀释剂0.25-1.25份。本发明的阴/非离子水性环氧固化剂，反应活性可控，具有良好的亲水性，水分散性能良好，可以分散或溶解在水中，有较
