Abstract

The invention belongs to the technical field of thin films and particularly discloses an antibacterial TPU (Thermoplastic Polyurethane) and PVC (Polyvinyl Chloride) blended composite film. The antibacterial TPU and PVC blended composite film is prepared from raw materials of the TPU, the PVC, polylactic acid, hydroxypropyl methacrylate, trifluoropropylmethyldichlorosilane and the like. A preparation method of the antibacterial TPU and PVC blended composite film comprises the following steps: firstly, mixing the TPU with the PVC and mixing; secondly, heating the molten mixture obtained in the first step and plasticizing until complete plasticizing is finished; thirdly, filtering the completely-plasticized mixture, removing impurities and the like. The antibacterial TPU and PVC blended composite film prepared with the preparation method disclosed by the invention has better sterilization and antibacterial effects and longer service life; by using TPU and PVC blended modified composite fabric, the two substance are blended to fully realize respective characteristics. The weather resistance, wear resistance, oil resistance, chemical resistance, low temperature resistance and bonding characteristics with other resin of the PVC can be improved by using the TPU to modify the PVC, and further the impact strength of the PVC is improved.

Description

technical field [0001] The invention belongs to the technical field of thin films, and in particular relates to a composite film blended with antibacterial TPU and PVC and a preparation method thereof. Background technique [0002] TPU film is a film made by special processes such as calendering, casting, film blowing and coating on the basis of TPU pellets. Thickness 0.01 to 2mm.
