Problems solved by technology

Nano-silver has antibacterial and anti-virus effects. In order to improve the antibacterial performance of masks, nano-silver ions or nano-silver particles are often added in the process of preparing masks. However, the traditional nano-silver materials have poor adhesion to the fiber matrix, and there are nano-silver particles. The risk of precipitation has a certain degree of danger, and limits the antibacterial and antiviral capabilities of nano silver masks

Abstract

The invention discloses a silver nanowire antibacterial layer and a silver nanowire mask. The preparation method of the silver nanowire antibacterial layer comprises the following steps: (1) mixing silver nanowires and an organic silicon modifier in ethylene glycol to obtain a reaction stock solution with the mass fraction of the silver nanowires being 0.01-0.05% and the mass fraction of the organic silicon modifier being 1-3%, carrying out a mechanical stirring reaction to obtain a reaction solution, and cleaning and blow-drying the reaction solution to obtain modified silver nanowires; (2) adding a mixed solution composed of water, ethyl alcohol and isopropyl alcohol into the modified silver nanowires so as to obtain 0.005%-0.1% of silver nanowire turbid liquid; and (3) uniformly spraying or dipping the silver nanowire turbid liquid on a PTFE film, and sintering at low temperature to obtain the silver nanowire antibacterial layer. The silver nanowires modified by ethylene glycol andthe organic silicon modifier so that the silver nanowires have higher adhesive force on the PTFE film and are easier to sinter at low temperature, and the silver nanowire particles on the prepared nano antibacterial layer are more uniformly distributed.

Description

technical field [0001] The invention relates to the field of nano-silver wires, in particular to a nano-silver wire antibacterial layer and a nano-silver wire anti-mask. Background technique [0002] During the period when the virus is raging, the clearest known transmission method is saliva transmission, and frequent wearing of masks has become one of the most important anti-corrosion measures. With the development of the situation, mask resources are extremely scarce, especially medical masks with significant antibacterial and antibacterial effects. [0003] The new type of coronavirus pneumonia is extremely contagious. In addition to the substantial increase in the production capacity of antibacterial masks, higher requirements are also placed on the antibacterial properties of masks. Nano-silver has antibacterial and anti-virus effects. In order to improve the antibacterial performance of masks, nano-silver ions or nano-silver particles are often added in the process of...
