“…Type II water-based epoxy curing agents are mostly fatty amines with hydrophilic ends, epoxy-amine, and polyamide curing agents. [22][23][24] Elmore 25 first added polyvinyl polyamine to epoxy resin (EP1001), then reacted with carboxylated polyether alcohol to prepare amide amine compounds, and finally the amide-amine water-based epoxy curing agent was obtained by sealing the monocyclic oxide compounds. Zou 26 used octadecylamine and ethylene glycol diglycidyl ether as raw materials in the first reaction and then sealed the end with triethylenetetramine in the second step.…”

Owing to the requirement for environmental protection, water-based coatings have become a significant trend in the development of coatings. The water-based epoxy curing agent has also become a hot research topic. In this study, a B-A-B epoxy compound with a long hydrophobic alkyl chain connected to the intermediate nitrogen atom was synthesized at both ends of a molecule using ethylene glycol diglycidyl ether and 3,4-dimethoxyaniline as raw materials. Subsequently, the epoxy compound was sealed with triethylenetetramine. A nonionic, water-based epoxy resin curing agent with amino groups at both ends of the molecule was prepared. The target product structure was confirmed by infrared spectroscopy (IR), Mass spectrum (MS), and Nuclear magnetic resonance hydrogen spectroscopy (1H-NMR). Additionally, through three factors and three levels of orthogonal experimental design, the optimum experimental conditions were confirmed, the optimum yield was 82.83%. The thermogravimetric analysis (TGA) indicated that the monomer exhibited a significant weight loss in the temperature range of 320–450°C. The pencil hardness, flexibility, and impact resistance of the waterborne epoxy resin coating film prepared by the non-ionic water-based epoxy curing agent reached or exceeded those of similar products at China and foreign countries.

Polyurethane acrylate modified epoxy acrylate resin with high solid content and great mechanical properties was synthesized by addition of polyethylene glycol in this work. The conversion process from liquid to solid was confirmed by comparing the FT-IR of oligomer and film. The disappearance of the carbon-carbon double bond absorption peaks at 1639 cm−1 and 819 cm−1 indicates that the oligomer is cured completely. In addition, the thermal analysis of the resin was characterized by differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). According to the experimental data, it can be seen from that the resin started to decompose at 293.31 until it is almost completely decomposed at 481.73°C which indicated that the stability of the film was better and the decomposition temperature was higher. In addition: Compared with the thermosetting resin E51 and the modified resin, the glass transition temperature is reduced by about 31 °C, which solves the problem of brittleness and hardness.
