Anti-haze disinfecting mouth mask and preparation method

Abstract

Provided are an anti-haze disinfecting mouth mask and a preparation method. The mouth mask comprises a mask body, the mask body is provided with a filter element pocket, and the filter element pocket is internally provided with an isolation filter element. The isolation filter element is formed by a non-woven fabric layer, a carbon fiber layer, and a disinfection layer. The middle part of the disinfection layer is gauze, and double surfaces of the gauze are coated with titanium dioxide chitosan films. The method comprises: preparing a TiO2 sol, preparing a chitosan liquid sol, performing magnetic stirring and ultrasonic vibration, coating to form a film, and preparing a filtering element. The mouth mask has good antibiosis disinfection and haze prevention effects, and has a function of absorbing and filtering heavy metal ions. The mouth mask is good in water absorption permeability, and can rapidly absorb steam discharged by respiration, so as to reduce adverse effect of water mist on glasses in cold weather. The isolation filter element can be cleaned by water or water vapor, and can be used repeatedly, so as to greatly reduce use cost of the anti-haze mouth mask.

Description

technical field [0001] The invention relates to a mask and a preparation method, in particular to an anti-fog and haze disinfection mask provided with washable and replaceable filters. Background technique [0002] A mask is a commonly used sanitary protection product. With the rapid development of the industrialization process, the air pollution is becoming more and more serious, the air quality is deteriorating, and the frequent occurrence of haze weather poses a threat to people's health, especially for people who work outdoors for a long time. On the other hand, there are many kinds of viruses in the air. During the outbreak of infectious diseases such as influenza and bird flu, it is almost essential for people to wear masks when going out. Ordinary gauze or non-woven masks have been phased out due to their single function and inability to effectively isolate smog and viruses. Various masks with different structures are emerging, including masks with smog protection an...

AI Technical Summary

Problems solved by technology

But there are following problems in the mouth mask of prior art: 1, the effect that prevents the smog small particle inhalation lung less than 2.5 microns is not good; 2, antivirus disinfection function can't reach expected effect; , it includes a gauze functional layer containing chitosan particles. Chitosan is a green and environmentally friendly antibacterial finishing agent with antibacterial and disinfection functions, but the antibacterial activity of chitosan is low. This chitosan is attached in the form of particles Gauze layer, its adhesive force is lower, is easy to come off, once falls off then loses antiviral function, so this mouth mask is difficult to reach ideal antibacterial disinfection effect when actually using; In cold weather, the water mist produced by Kazakhstan will cause great trouble to those who wear glasses, so that they cannot wear masks; 4. Most of the existing anti-smog masks and disinfection masks are disposable products, which cannot be cleaned and used The time is short, which increases the cost of use and causes waste to a certain extent; 5. The existing masks lack the function of adsorption and isolation of heavy metal ions in the air
