This invention discloses an antibacterial masterbatch, an antibacterial material, and a method for preparing them. The antibacterial masterbatch comprises an antibacterial agent and a polymer material; the antibacterial agent is selected from any one or more of A+Y-. The invention prepares the antibacterial masterbatch by uniformly mixing the antibacterial agent with the polymer material, followed by melt blending, extrusion, and pelletizing in a twin-screw extruder. The antibacterial masterbatch of this invention can be directly (or after mixing with a base resin) melt-spun to obtain antibacterial fibers or spunbonded to obtain antibacterial nonwoven fabrics, exhibiting high antibacterial properties and wash resistance. The production process is simpler, and the organic antibacterial agent has better dispersibility and compatibility in the resin. The antibacterial agent in the antibacterial material of this invention is not easily detached, has good wash resistance, and provides a longer-lasting antibacterial effect.
