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

preparation example Construction

[0029] The preparation method of the anti-smog mask of the present invention comprises the making of cover body and isolation filter, wherein the making of isolation filter is the key technology of the method of the present invention, and isolation filter is prepared according to the following steps:

[0030] a. Configure TiO 2 Sol: Take absolute ethanol, tetrabutyl titanate, and water. The volume ratio of the above three substances is absolute ethanol: tetrabutyl titanate: water = 30:1:3, and three-thirds of the total amount of absolute ethanol 2. Mix and stir evenly with tetrabutyl titanate, mix the remaining absolute ethanol with water and drop into the mixture of absolute ethanol and tetrabutyl titanate, add acid solution to adjust the pH of the above mixture to 3, and continue stirring 2 hours, that is prepared into TiO 2 Sol.

[0031] b. Configure chitosan solution glue: configure chitosan solution glue according to the ratio of adding 1-5g chitosan and 5-25mg iodized ...

Abstract

An anti-fog and haze disinfection mask and its preparation method, the mask comprises a cover body, the cover body is provided with a filter bag, the filter bag is equipped with an isolation filter, and the isolation filter is composed of a non-woven fabric layer, a carbon fiber layer and a disinfection layer , the middle part of the disinfection layer is gauze coated with titanium dioxide chitosan film on both sides of the gauze. The method of the invention comprises the steps of configuring TiO2 sol, configuring chitosan solution glue, magnetic stirring, ultrasonic vibration, coating to form a film, and making a filter sheet. The mask of the invention has good antibacterial disinfection and anti-fog effects, has the function of absorbing and filtering heavy metal ions, has strong water absorption and air permeability, can quickly absorb water vapor discharged from breathing, and reduces the adverse effects of water mist on wearing glasses in cold weather. The isolation filter of the present invention can be washed with water or steam, can be used repeatedly, and greatly reduces the use cost of the anti-smog 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...
