The present invention relates to an excellent inorganic antimicrobial spray composition for an eco-friendly galvanized steel sheet duct, which comprises 5 to 20 wt% of acrylic resin mixed solution, 61 to 85 wt% of a solvent, and 1 to 20 wt% of an inorganic antimicrobial agent, wherein the inorganic antimicrobial agent of a ceramic material, where metal ions and metal oxides are exchanged or adsorbed on the ceramic material, is used to suppress proliferation of germs, provide a sterilizing effect, and adsorb and decompose toxic gases, thereby ensuring excellent antimicrobial activity and wherein the inorganic antimicrobial agent is non-toxic to a human body and antimicrobial activity thereof is semi-permanently persistent, thereby providing user convenience. In addition, the acrylic resin mixed solution having good adhesiveness and stability and excellent weather resistance is used, so that excellent workability and surface stability can be expected when the composition is coated on the surface of the duct. Furthermore, dimethylcarbonate is used as a solvent, a main ingredient of the composition to reduce generation of volatile organic compounds (VOC) compared to a conventional hydrocarbon-based solvent, thereby providing a very eco-friendly and safe working environment. |
