Abstract

The invention belongs to the technical field of materials, and particularly relates to antibacterial and antiviral slurry and a preparation method thereof, and an antibacterial and antiviral product. The antibacterial and antiviral slurry comprises antibacterial polypeptide, metal nanowires, a solvent and an auxiliary agent. The antibacterial and antiviral slurry provided by the invention simultaneously contains the components such as the metal nanowires, the antibacterial polypeptide and the auxiliary agent, has broad-spectrum sterilization and antibacterial effects, can kill germs in the environment in time, and has good antibacterial and sterilization effects. The antibacterial and antiviral slurry has an antibacterial rate of greater than 99% for escherichia coli, staphylococcus aureus and streptococcus albus, and has antiviral activity of greater than 99% to novel coronavirus and influenza A virus. The antibacterial and antiviral slurry is long in antibacterial and antiviral time efficiency, small in toxic and side effects and environment-friendly.

Description

technical field [0001] The application belongs to the technical field of materials, and in particular relates to an antibacterial and antiviral slurry and a preparation method thereof, and an antibacterial and antiviral product. Background technique [0002] The novel coronavirus pneumonia caused by coronavirus has attracted global attention, and the causative agent was identified as SARS-CoV-2. Since the outbreak of COVID-19 at the end of 2019, it has posed a serious threat to global public health and has had a fundamental and far-reaching impact on global life and economy. Controlling / preventing the spread of COVID-19 has become the top priority at present. Public places, including public transportation, hotels, medical and health institutions, etc., have the characteristics of dense flow of people and small spaces, which increases the difficulty of preventing and controlling the "environmental transmission" of viruses. According to reports, the new coronavirus can exist ...
