PURPOSE: A manufacturing method of epoxy resin composition is provided to obtain long pot-life time, to obtain a quick curing time, and to manufacture an epoxy resin composition with improved workability, profitability and physical properties. CONSTITUTION: A manufacturing method of epoxy resin composition comprises: a step of melt-mixing an epoxy resin(equivalent 184-196) and an epoxy resin(equivalent 230-270); a step of obtaining a base material by mixing lauryl glycidyl ether as a viscosity controller and silica fume; a step of preparing a hardener by adding triethylamine into metaxylenediamine phosphate, adding zinc octoate as a metal salt, adding silica fume, and adding urea modified solution; a step of mixing 100.0 parts by weight of the base material, and 10-30 parts by weight of the hardener just before impregnation of tube.
