Abstract: A method for manufacturing a water-based coating material is provided, including: (a) reacting tetraalkoxysilane, acidic aqueous solution of vanadium salt, and trialkoxyalkylsilane to form an oligomer; (b) reacting the oligomer with colloidal silica particles to form a modified oligomer; and (c) reacting the modified oligomer with trialkoxyepoxysilane to obtain a water-based coating material.
