Problems solved by technology

[0002] As a medical mask, in the prior art, it is generally a non-woven fabric type, which wraps the entire face below the eyes, which can effectively avoid the spread of bacteria. However, it has the following disadvantages: it cannot leak out the main parts of the human face —Mouth, the mouth is the main part that expresses the shape and expression of a person. Masks cover the mouth, which is not good for communication, and it is not easy to establish mutual trust and understanding with patients; existing medical masks are disposable masks and cannot be reused
However, the antibacterial and antiviral effect of the mask is relatively poor
[0006] CN207444323U discloses a kind of medical transparent mask, it has solved the technical problems such as existing mask use inconvenience
However, as a medical mask, its antibacterial effect needs to be further improved

Abstract

The invention relates to an antibacterial and antiviral master batch for a transparent mask, a preparation method of the antibacterial and antiviral master batch and the antibacterial and antiviral transparent mask. The antibacterial and antiviral master batch for the transparent mask comprises the following components in parts by weight: 80-90 parts of first transparent resin, 5-10 parts of a silver-containing inorganic nano material, 1-5 parts of a first antioxidant and 1-5 parts of a first dispersing agent. The antibacterial and antiviral master batch is added into the raw materials of thetransparent mask; the antibacterial and antiviral transparent mask is obtained after extrusion molding, efficient and lasting antibacterial, mildew-proof and antiviral effects are achieved, the antibacterial rate of escherichia coli and staphylococcus aureus reaches 99% or above, the mildew-proof grade is zero, and the antiviral activity rate of influenza A viruses such as H1N1 and H3N2 reaches 99% or above.

Description

technical field [0001] The invention relates to the technical field of antibacterial masks, in particular to an antibacterial and antiviral masterbatch for a transparent mask, a preparation method thereof, and an antibacterial and antiviral transparent mask. Background technique [0002] As a medical mask, in the prior art, it is generally a non-woven fabric type, which wraps the entire face below the eyes, which can effectively avoid the spread of bacteria. However, it has the following disadvantages: it cannot leak out the main parts of the human face —Mouth, the mouth is the main part of expressing human form and expression. Masks cover the mouth, which is not good for communication, and it is not easy to establish mutual trust and understanding with patients; existing medical masks are disposable masks and cannot be reused. [0003] There is a transparent mask in the prior art, but it is generally all semi-closed, and some fully closed, but its structure is complex, and ...
