Abstract

The invention belongs to the technical field of PVC films, and particularly relates to an antibacterial and antiviral PVC film and a preparation method thereof.The PVC film comprises, by weight, PVC resin powder, a plasticizer, a coupling agent, a stabilizer, diatomite powder, a vanillin antibacterial agent, a graphene-based composite antiviral material, a lubricant and a flame retardant. The antibacterial and antiviral component can easily capture bacteria and viruses, initiate ROS and generate high active oxygen, other ions and free radicals adhere to the surfaces of the viruses, the structures and functions of virus protein and nucleic acid are destroyed, the captured bacteria and viruses can be rapidly inactivated through a contact catalysis type antibacterial and antiviral mechanism, and the antibacterial and antiviral effect is good. And the antiviral activity rate on germs such as new coronavirus COVID-19, escherichia coli, staphylococcus aureus and the like is greater than 99%.

Description

Technical field [0001] The present invention belongs to the field of PVC membrane technology, specifically relates to an antibacterial antiviral PVC membrane and a method of preparation thereof. Background [0002] In the past two years, with the outbreak of various viruses such as new influenza and new coronaviruses, and bacteria such as Klebsiella pneumoniae, the sterilization and disinfection of space have become our daily routine. Recognizing the cumbersome and inconvenient sterilization work, the waste of resources and the potential harm, the antibacterial and antiviral on the surface of the object has become a general choice. From this point of view, the demand for functional membrane materials with antibacterial and antiviral properties is increasing. [0003] As such a functional membrane material with antibacterial and antiviral properties has been reported. CN105348756B discloses an antibacterial polyester film and its preparation method and its use, the nano silver is ...
