[0003] The existing Chinese patent literature (publication number: CN103627197B) discloses an antibacterial thermoplastic composition and a preparation method thereof. The composition includes the following components blended: thermoplastic resin: 100 parts by weight; antibacterial agent 0.3 to 3 parts by weight parts; wherein the antibacterial agent is antibacterial glass powder, including the following components by weight percentage: P2O5 30-40wt%; Na2O or K2O 6-18wt%, ZnO 50-60wt%; Ag2O 0-0.09wt%; The average particle size of the antibacterial glass powder is 0.05-100um. The plastic uses oxides as antibacterial materials. The properties of the oxides are relatively stable, and the effect on bacteria is not obvious.
[0004] Chinese patent document (publication number: CN1803898B) discloses a kind of nano antibacterial plastic, it is to make antibacterial masterbatch by nano antibacterial particle first with resin, auxiliary agent, and antibacterial masterbatch mixes injection molding machine or extrusion with base resin again Extrusion molding machine to obtain antibacterial plastics; or mixing, injection molding machine injection molding or extruder extrusion molding to make antibacterial plastics. The plastics use antibacterial materials more conventionally, and the antibacterial effect is not good.
