Antibacterial and antiviral film and preparation method thereof

Abstract

The invention discloses an antibacterial and antiviral film and a preparation method thereof, and belongs to the technical field of antibacterial and antiviral materials, wherein the antibacterial and antiviral film comprises the following materials: thermoplastic polyurethane elastomer rubber, epoxy resin, an auxiliary agent, a dispersant, a stabilizer, an antibacterial agent and a surface coating agent; a nano inorganic composite coating layer is arranged on the surface of the material, so that various special ion viruses which are non-toxic to human bodies can be continuously released at normal temperature; transcriptase, reverse transcriptase, polymerase and polymerase are required to participate in a replication process; the ions can enable enzyme to be inactivated so as to cut off virus replication of bacteria, the mould needs respiratory enzyme to provide energy in the metabolic process, and the ions can enable the respiratory enzyme to be inactivated so as to inhibit proliferation of the bacteria and the mould; and the film has long-acting broad-spectrum antibacterial and antiviral properties, has the characteristics of high definition and no discoloration after long-term use, can inhibit the activity of protease, can prevent DNA replication, and can effectively block contact propagation.

Description

technical field [0001] The invention belongs to the technical field of antibacterial and antiviral materials, and in particular relates to an antibacterial and antiviral film and a preparation method thereof. Background technique [0002] With the development of science and technology, various materials have been discovered and prepared, including antibacterial and antiviral materials. Antibacterial and antiviral materials have different appearances due to their different states. Among them, antibacterial and antiviral films, as the name implies, are film-shaped Antibacterial and antiviral materials are widely used. Generally speaking, bacteria and viruses widely exist in the air (droplets, floating dust and aerosols, etc.) and the surrounding environment, including indoor closed spaces, tables and chairs in public places, office equipment, and self-service in public places. Equipment and elevator buttons, etc., therefore require an antibacterial and antiviral film. [0003...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is: in order to solve the problem that the traditional antibacterial and antiviral film is not equipped with nano-inorganic composite coating, and cannot continuously release a variety of special ion viruses that are not poisonous to humans at room temperature, resulting in that the antibacterial effect of the film cannot be achieved. At the same time, the main material does not use TPU material, which cannot achieve the effect of material skin-friendly, and the product quality cannot be guaranteed. Therefore, an antibacterial and antiviral film and its preparation method are proposed
