Polyether amine type water-based epoxy curing agent for epoxy resins and preparation method of curing agent

The invention discloses a polyether amine type water-based epoxy curing agent for epoxy resins and a preparation method of the curing agent. The water-based epoxy curing agent is prepared from polyether amine and maleic anhydride. The polyether amine is modified by anhydride by virtue of the optimum steps and conditions in a preferred scheme, and the polyether amine type water-based epoxy curing agent is prepared. The curing agent is high in solid content and low in viscosity. When the curing agent is applied to a water-based epoxy floor level, the construction process is clean and environment-friendly, no volatile organic compound is produced, various properties of the cured floor level can meet the market requirements, and excellent technical effects are achieved. 本发明公开了种环氧树脂用的聚醚胺型水性环氧固化剂及其制备方法，它由聚醚胺和马来酸酐制成。本发明通过优选方案将聚醚胺经酸酐通过最佳的步骤和条件进行改性，制备得到聚醚胺型水性环氧固化剂，该固化剂固含高，粘度低，应用于水性环氧地坪中，施工过程清洁环保，无有机挥发性气体，固化后的地坪各方面性能均满足市场需求，取得了非常好的技术效果。
