With chemical modification method, the epoxy resin E44 was modified into water-borne epoxy resin by diethanolamine, considering the compatibility of curing agent and resin, diethylenetriamine was modified into epoxy amine curing agent as well, through single factor method to discuss the effects of reactant ratio, reaction temperature on the results of the product, the structure of the product was analyzed by Infrared spectrum. The experimental results showed that, when molar ratio of epoxy resin and diethanolamine was 4:3, reaction temperature of 70-80°C, the preparation of waterborne epoxy resin emulsion has small particle size and good stability. At the same time, when molar ratio of epoxy resin and diethylenetriamine was 1:1, reaction temperature of 80°C, the performance of waterborne epoxy curing agent is well.

This paper presents the synthesis of a new type of flexible epoxy curing agent and an approach to improve the toughness of epoxy resin by curing without reducing the strength and modulus of the resin-cured material. The results show that the degree of toughness reaches maximum values when the flexible curing agent is applied at weight percentages (wt.%) between 10% and 15%. When the amount of flexible curing agent added to epoxy resin weight is 10wt.%, the impact toughness and fracture toughness increases by 33.3% and 96.3%, respectively, compared with the pure epoxy resin. When the amount of flexible curing agent added to epoxy is 10wt.%, the resulting impact thoughness of the material is 19.5 kJ•m-2 at-50°C, the impact toughness of pure epoxy resin is only 7.96 kJ•m-2.
