The composite of water-based coating agent for surface treatment and manufacturing method of water-based coating agent

The present invention relates to an aqueous coating agent composition for surface treatment and a method for manufacturing the same, and more specifically, using an inorganic binder in a sol or gel state as a natural mineral dissolved in nature, water as a solvent, ethanol, crosslinking agent and dispersant It relates to a water-based coating agent composition for surface treatment comprising a method, and to a method for producing a water-based coating agent composition for the surface treatment safely by adjusting the input order and the method of feeding. According to the present invention, it is possible to provide an environment-friendly coating composition containing no heavy metals and aromatic compounds, and has a high coating film hardness, excellent wear resistance, solvent resistance, heat resistance, etc. There is an effect that can provide.
