Long-acting antiviral and antibacterial liquid, preparation method thereof and application of long-acting antiviral and antibacterial liquid in preparation of mask

Abstract

The invention discloses long-acting antiviral and antibacterial liquid, a preparation method thereof and application of the long-acting antiviral and antibacterial liquid in preparation of masks. The antiviral and antibacterial liquid comprises the following components in parts by weight: 0.5-2 parts of nano-silver sol, 1-5 parts of an organic antibacterial agent, 8-15 parts of a cosolvent, 5-15 parts of a polymer adhesive and 50-80 parts of water. The preparation method comprises the following steps: S1, mixing and stirring the organic antibacterial agent and the cosolvent in parts by weight to obtain a solution A; s2, adding water into the solution A, and stirring to obtain a solution B; s3, adding a polymer adhesive into the solution B, stirring, and cooling to room temperature to obtain an emulsion C; and S4, adding nano-silver sol into the emulsion C, and stirring to obtain the long-acting antiviral and antibacterial liquid. According to the application, the long-acting antiviral and antibacterial liquid is applied to preparation of a novel antiviral and antibacterial protective mask. The prepared novel anti-virus and anti-virus protective mask integrates the quick-acting and stable anti-virus and anti-virus functions, the lasting protection function and the like, and the defects that an existing protective mask is short in anti-virus and anti-virus time, complex in process, low in production efficiency, slow in effect and the like are overcome.

Description

technical field [0001] The invention relates to the technical field of antibacterial materials, in particular to a long-acting antiviral and antibacterial liquid, its preparation method and its application in the preparation of masks. Background technique [0002] At present, general protective masks can only block the passage of virus particles, but cannot achieve the purpose of killing and inhibiting virus activity, that is to say, the protective effect of ordinary masks is limited; Bacteria have a certain protective effect, but the killing effect on viruses such as influenza A, avian influenza, hand-foot-mouth disease, and coronavirus HcoV229E is not ideal, and there are a series of problems such as slow effect, short timeliness, and complicated process . [0003] Chinese invention patent CN2597013A discloses a bactericidal health-care mask. The mask contains an inner layer and an outer layer, and a virus-killing layer is arranged between the inner layer and the outer la...

AI Technical Summary

Problems solved by technology

[0004] For existing antibacterial and antiviral masks have defects such as complicated production process, slow effect and short effective time of mask protection, the present invention provides a long-acting antiviral and antibacterial liquid and uses it in the preparation of new antiviral and antibacterial protective masks , so that the prepared new anti-virus and anti-bacterial protective mask integrates anti-bacterial and anti-virus functions, quick-acting and stable, and long-lasting protection functions, which solves the defects of existing protective masks, makes it safer to use, and avoids personnel infection
