Anti-smog face mask filter sheet

Abstract

The invention discloses an anti-smog face mask filter sheet. The filter sheet is of a three-layer nano-fiber film composite structure, the upper layer is nano-silver antibacterial fiber film, the middle layer is activated carbon nano-fiber film, the lower layer is traditional Chinese medicine antibacterial fiber film, the activated carbon nano-fiber film is obtained by oxidizing in advance and conducting carbonization treatment on a high polymer material / activator composite nano-fiber precursor prepared through an electrospinning method, the nano-silver antibacterial fiber film is formed through electrospinning compounding on the upper surface of activated carbon nano-fiber, and the traditional Chinese medicine antibacterial fiber film is formed through electrospinning compounding on the lower surface of the activated carbon nano-fiber. When the filter sheet is applied to a face mask, a very good filtering effect can be exerted on small-particle tiny dust, the filter sheet is good in breathability, harmful bacteria in air can further be filtered out and killed, and the health of the respiratory system can be better guaranteed.

Description

technical field [0001] The invention belongs to the category of health care, in particular to an anti-smog mask filter. Background technique [0002] Smog refers to a kind of particulate matter in the atmosphere with an aerodynamic equivalent diameter less than or equal to 2.5 microns, also known as particulate matter that can enter the lungs. Although smog is only a small component in the earth's atmosphere, it has an important impact on air quality and visibility. Smog has a small particle size, is rich in a large amount of toxic and harmful substances, stays in the atmosphere for a long time, and is transported over a long distance, so it has a greater impact on human health and the quality of the atmospheric environment. my country's air pollution situation is grim. Living and working in an environment with poor air quality for a long time will not only cause a decrease in respiratory function and aggravate respiratory symptoms, but also lead to chronic bronchitis, bro...

Problems solved by technology

The filters on the market mainly emphasize the filtering function, and the filtering effect is uneven. At the same time, even if the filter blocks the smog particles in the air, the filtered particles and bacteria are easy to attach to the mask (filter) close to the mouth. The part of the nose causes the growth of bacteria and forms secondary pollution, which can easily cause respiratory diseases and endanger human health
