Preparation method of novel waterborne epoxy resin curing agent

The invention provides a novel waterborne epoxy resin curing agent and a preparation method thereof, and belongs to the field of epoxy resin curing agents. According to the preparation method, the novel waterborne epoxy resin curing agent is prepared by using a modified novel flame retardant (PEME) to modify isoprene, and adopting a bio-based material, namely dopamine which is wide in sources andlow in price, to perform double-end-capping treatment. The curing agent provided by the invention can achieve rapid curing at room temperature and has excellent flame retardancy. 本发明提供了一种新型水性环氧树脂固化剂及其制备方法，属于环氧树脂固化剂领域。本发明以改性的新型阻燃剂（PEME）修饰异戊二烯，并采用来源广泛、价格低廉的生物基材料多巴胺进行双封端处理，制备得到的新型水性环氧树脂固化剂。本发明的固化剂可实现室温快速固化并且具有优异的阻燃性能。
