PURPOSE: A quick-curable water-soluble epoxy composition is provided to be cured within two hours after spreading at room temperature, not to contain organic solvent, and to have short construction time. CONSTITUTION: A quick-curable water-soluble epoxy composition comprises water-soluble bisphenol A type epoxy epichlorohydrin, water-soluble polyamide, 3-glycidoxypropylmethyldiethoxysilane, and one or more additives selected from a frame retardant, a surfactant, a moisturizer, an antifoaming agent, graphite and water. A manufacturing method of the epoxy composition comprises: a step of putting the water-soluble bisphenol A type epoxy epichlorohydrin and water in order; a step of heating the materials; a step of putting the 3-glycidoxypropylmethyldiethoxysilane into the solution; a step of keeping the solution for one hour, and cooling temperature to room temperature; and a step of putting a frame retardant, a surfactant, a moisturizer, an antifoaming agent or graphite.
