Abstract

The invention provides a medical antibacterial film material which comprises by mass 30 to 50 parts of polyvinyl chloride resin, 10 to 30 parts of acetyl citrate, 10 to 20 parts of nano-crystalline cellulose glue, 8 to 20 parts of modified cyclodextrin, 0.8 to 8 parts of an antimicrobial drug, 0.8 to 4 parts of nano tourmaline powder, 2-5 parts of a photosensitizer, 2-5 parts of an antioxidant, and 2 to 5 parts of an antistatic agent. The modified cyclodextrin is grafted cyclodextrin cationic starch prepared as follows: after reaction of cyclodextrin and an epoxy crosslinking agent under alkaline conditions, the cyclodextrin and gelatinized cationic starch are reacted while stirring, pH is adjusted to neutrality while the stirring, an organic solvent is added, and centrifugal separation and freeze-drying are performed. The polyvinyl chloride resin is used as a base material, and the modified cyclodextrin containing the antimicrobial drug and the nano tourmaline powder is added, so thatthe film material has long-lasting antibacterial activity and negative ion release performance.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a medical antibacterial film and a preparation method thereof. Background technique [0002] Polyvinyl chloride (PVC) material itself is relatively hard. After adding plasticizer, PVC becomes soft and elastic, easy to form and process, and can be made into medical products of various shapes, so it has become a widely used medical product at present. s material. However, medical film products not only require different softness and strength according to different use requirements, but also require the film to be antibacterial and non-toxic. However, the existing medical antibacterial films have short antibacterial action time and poor antibacterial effect, so it is necessary to propose a medical film material capable of long-term antibacterial. Contents of the invention [0003] Based on above prior art, the object of the present invention is to provide a...
