Problems solved by technology

[0004] 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

Provided are a modified nanometer bamboo charcoal mask and a manufacturing method thereof. The modified nanometer bamboo charcoal mask comprises an inner mask and an outer mask, wherein the inner mask is provided with a dismounting opening, and a filer layer is arranged in the dismounting opening. The inner mask and the outer mask of the mask and a filer layer base plate are made of an electrets melt-blowing polypropylene fiber non-woven fabrics, the filer layer uses chitosan as a capsule wall material, microcapsules are made from modified nanometer bamboo charcoal powder, beewax is used as an adhesive for arranging the microcapsules on the non-woven fabrics. The modified nanometer bamboo charcoal powder are modified by adopting nanometer titanium dioxide. The modified nanometer bamboo charcoal mask is green, environment-friendly, safe and efficient, has the broad-spectrum antibacterial effect and has good washability due to the fact that the beewax is used as the adhesive to arrange the microcapsules on the non-woven fabrics.

Description

technical field [0001] The invention relates to the field of medical and health technologies, in particular to a modified nano-bamboo charcoal mask capable of antibacterial and sterilizing. Background technique [0002] 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 students in colleges, ...
