Water emulsion type epoxy curing agent as well as preparation method and application thereof

The invention relates to the field of epoxy curing agents, in particular to a water emulsion type epoxy curing agent, a preparation method and application. The water emulsion type epoxy curing agent is composed of the following components: 30 wt%-40 wt% of an epoxy prepolymer solution; 10 wt% to 25 wt% of an alicyclic polyamine; 2 wt%-5 wt% of an end-capping reagent; 40 wt%-50 wt% of deionized water; wherein the epoxy prepolymer solution is composed of the following components: 15-25 wt% of polyether amine unit amine; 55wt%-70wt% of epoxy resin; 10 wt% to 15 wt% of a hydrophilic agent; and 5 wt%-7 wt% of a solvent. The epoxy curing agent is prepared from the non-water-soluble amine, the price is low, the production cost is low, and when the epoxy curing agent is applied, epoxy resin has better mechanical properties and corrosion resistance. 本申请涉及环氧固化剂领域，尤其是涉及一种水乳型环氧固化剂、制备方法及应用。水乳型环氧固化剂由以下组分组成：环氧预聚物溶液30wt%~40wt%；脂环族多元胺10wt%~25wt%；封端剂2wt%~5wt%；去离子水40wt%~50wt%；其中，所述环氧预聚物溶液由以下组分组成：聚醚胺单元胺15wt%~25wt%；环氧树脂55wt%~70wt
