Problems solved by technology

However, most of the mask products currently on the market cannot filter PM2.5. The test results of the China Consumers Association in 2014 showed that only a very small number of foreign products met the removal efficiency requirements, and most of these products were designed for industrial production. The safety and aesthetics are difficult...

Abstract

The invention discloses a composite nanofiltration anti-haze antibiotic inhibition mask based on grapheme oxide. The mask comprises a mask body which is formed by sequentially stacking an anti-static processing layer, a grapheme oxide/silica/polymer composite nanometer filter core layer, an anion fiber non-woven fabric layer and an antibacterial layer from outside to inside. The outer exposed surface of the anti-static processing layer is provided with symmetrical fixing buckles, and a resistance band is detachably connected with the fixing buckles, and the mask body is bonded through hot-press to form the mask with a stereo breathing space. The polypropylene nonwoven fabric is loaded with the core filtration material made of the grapheme oxide/silica/polymer composite nanometer filter core layer, the anion fiber non-woven, the antibacterial layer by the method of the electrostatic spinning, the outermost layer of the propylene nonwoven fabric is treated by antistatic electricity. The anti-haze antibiotic inhibition face mask has the advantages of being high in efficiency of filtering away PM2.5 haze and good in permeability. The mask also has the functions of releasing negative ions to breath, resisting bacteria, low temperature far infrared and ultraviolet ray and the like.

Description

technical field [0001] The invention relates to the technical field of anti-haze masks, in particular to a composite nanofiltration anti-haze antibacterial and bacteriostatic mask based on graphene oxide and a preparation method thereof. Background technique [0002] In recent years, the rapid increase in the number of automobiles in my country and the rapid development of industrialization have led to the deterioration of air quality, and the duration of smog days has become longer and longer. Continuous smog weather has had a very serious impact on human health and daily life. As a result, various diseases are caused, including respiratory diseases such as asthma, respiratory tract infection, and lung infection, which have a very serious impact on people's health, especially for groups with weak immunity such as children and the elderly. [0003] Sources of toxic particulate matter in cities: automobile exhaust. Vehicles that use diesel are the “repeat offenders” that emit ...
