The invention discloses an antibacterial thermoplastic polyurethane net film for clothing and a preparation method thereof, wherein the antibacterial thermoplastic polyurethane net film for clothing is prepared from the following raw materials in parts by mass: 20-40 parts of isocyanate, 50-80 parts of polyester polyol, 4-12 parts of chain extender, 10-15 parts of composite antibacterial agent, 0.005-0.05 part of catalyst and 0.2-2 parts of additive, wherein the composite antibacterial agent is chitosan-Ag + A complex compound. The invention has excellent antibacterial effect and uses chitosan-Ag + The complex is used as a composite antibacterial agent, the antibacterial effect of the TPU is effectively enhanced through the synergistic effect of the organic chitosan and the inorganic silver ions, and the thermoplastic polyurethane net film has excellent antibacterial property and better bonding strength by matching with the raw materials of the components. |
