Resin composition for antibacterial filter, method for preparing same, and antibacterial filter using same

A method for preparing a resin composition for an antibacterial filter, the method comprising:

• melting antibacterial glass powders that include:
• 26 to 50 wt % of SiO2;
• 0.5 to 4 wt % of at least one of B2O3 or P2O5;
• 15 to 27 wt % of Na2O and K2O;
• 3 to 20 wt % of at least one of CaO, MgO, or WO3;
• and
• 22 to 44 wt % of at least one of ZnO or SnO,
• based on 100 wt % of the antibacterial glass powders;
• cooling the melted antibacterial glass powders;
• adding a silane coupling agent having a cationic functional group to the cooled antibacterial glass powders, and pulverizing the cooled antibacterial glass powders to prepare an antibacterial glass composition;
• and
• mixing the prepared antibacterial glass composition with a resin.
