Problems solved by technology

[0005] At present, many masks with bamboo charcoal function are made of bamboo charcoal fiber cloth. Compared with traditional medical masks, the adsorption function is not significantly improved, and the multi-layer structure is still used, which affects the air permeability.
There is also a filter mask, which generally uses independent activated carbon particles or bamboo charcoal (charcoal) sheets in gauze or filter screens. Its larger solid shape not only causes inconvenient use, but also its specific surface area and adsorption speed are not as good as large powdered bamboo charcoal

Abstract

The invention provides an environment-friendly bamboo charcoal mask and a manufacturing method thereof. The mask comprises an inner mask body and an outer mask body, the inner mask body is provided with a detachment opening, a filtering layer is arranged in the detachment opening, the inner mask body, the outer mask body and the filtering layer are all made of electret melt-blown polypropylene fiber non-woven fabrics, chitosan serves as a capsule wall material of the filtering layer, nanometer bamboo charcoal powder serves as a core material to be made into micro capsules, and the microcapsules are arranged on the non-woven fabrics through beewax serving as adhesive agents. The chitosan, the bamboo charcoal powder and the beewax are all natural materials, the obtained product is environmentally friendly, safe and efficient and has a broad-spectrum antibacterial function, the microcapsules are arranged on the non-woven fabrics through the beewax serving as the adhesive agents, and good washability is achieved.

Description

[0001] technical field [0002] The invention relates to the field of medical and health technologies, in particular to an environment-friendly bamboo charcoal mask capable of antibacterial and sterilizing. Background technique [0003] Some human diseases are currently transmitted through the respiratory tract, such as SARS virus, parainfluenza virus, respiratory syncytial virus, coronavirus, adenovirus, mumps virus, measles virus, rubella virus, varicella-zoster virus, etc. . These viruses seriously threaten people's health and even endanger people's lives. Many viruses exist in the patient's nasal mucus, saliva, sputum and other secretions, which can be transmitted by air and droplets. In addition, they are also related to contaminated eating utensils, which brings great difficulty to prevention, and is prone to epidemics and even global outbreaks. sex pandemic. People who work in a relatively closed environment, people who are often in a crowded environment, and stude...
