Problems solved by technology

However, the bactericidal and virus-killing performance of masks is not ideal. Due to the performance limitations of anti-bacterial materials, the current "anti-bacterial" masks can only achieve anti-bacteria, but cannot kill super bacteria and viruses.
Or in order to improve the barrier and filtration efficiency of viruses, the existing medical masks use multi-layer melt-blown materials, which makes the masks have insufficient air permeability and bulkiness, and it is even more difficult to achieve both sterilization and virus killing rates as well as air permeability and bulkiness. both
For countless medical staff, it will undoubtedly increase the burden of breathing and the pressure of work in a highly stressful and long-term heavy working environment

preparation example Construction

[0046] On the other hand, the preparation method of the filter layer of the aforementioned virus-killing mask, such as figure 1 shown, including the following steps:

[0047] S01. Prepare a composite metal wire rod by combining metal silver and copper, wherein, by weight percentage, silver is 40%-80%, and the rest is copper.

[0048] In a preferred embodiment, metal silver and metal copper wires are braided and rolled into a composite metal wire rod, wherein, by weight percentage, silver is 60% to 80% and the rest is copper.

[0049] S02. Use the composite metal wire rod as the anode conductor of the DC power supply to form an arc with the cathode. The temperature of the arc is above 5000°C, so that the tip of the metal wire rod of the anode conductor is vaporized and evaporated to produce smoky metal atom groups, silver metal atoms Fully mixed with copper metal atoms to form a gaseous alloy.

[0050] In a preferred embodiment, the composite metal wire rod is used as the ano...

Abstract

The invention discloses a virus-killing mask and a preparation method of a mask filter layer. The middle layer of the mask body is at least one layer of melt-blown non-woven fabric made of a virus-killing filter layer; the virus-killing filter layer is made of a polypropylene composite material, is a virus-killing polypropylene composite material, and is prepared from the following components in percentage by weight: 95-99% of polypropylene and the balance of a nano silver-copper alloy material; the nano-silver copper alloy material is formed by mixing nano-silver copper alloy particles with the particle size of 15 nm-50 nm, the copper metal atom form of the outer surface of the alloy material is copper oxide, and the nano-silver copper alloy material comprises, by weight, 40%-80% of silver and the balance copper. Through detection, the antibacterial rate of the virus-killing mask on escherichia coli and staphylococcus aureus representing conventional strains and methicillin-resistantstaphylococcus aureus representing super bacteria reaches 99% or above.

Description

technical field [0001] The invention belongs to the technical field of composite filter materials, and in particular relates to a virus-killing mask and a method for preparing a filter layer of the mask. Background technique [0002] In recent years, with the development of the economy and the improvement of people's living standards, people's requirements for the quality of the environment are getting higher and higher. But at the same time of economic development, it also brought a series of environmental problems. For example, in smoggy weather, smog is mainly composed of sulfur dioxide, nitrogen oxides, and inhalable particulate matter. These fine particulate matter inhaled into the human body may cause great damage to the respiratory tract and lungs. There are also SARS virus and novel coronavirus pneumonia, which can be transmitted through droplets, contact and other ways. For ordinary people, ordinary medical masks can be worn, but for hospital medical staff and epi...
