Description
Technical field
The present invention relates to antibacterial mask technical field, the anti-haze of more particularly to a kind of antibacterial green based on graphene oxide
Mouth mask and preparation method thereof.
Background technology
In recent years due to the quickening of process of industrialization, the aggravation of various pollutions makes the environment of human survival constantly deteriorate, and passes
Poison, the potential intrusion chance of germ of catching an illness increase, and respiratory infectious disease has spread speed easy soon by the spittle and air borne
The characteristics of touching wide incidence of disease of group is high causes very big threat to public health and social stability；China has many cities all to go out simultaneously
Showed a certain degree of haze weather, PM2.5 is medically referred to as pellet, be Atmospheric Grains diameter be less than or
Pollutant equal to 2.5 microns, general mouth mask filtering PM2.5 effects are poor on the market at present, it is impossible to effective to stop
PM2.5.PM2.5 particulate matters can effectively be filtered by wearing protective mask, block pathogenic microorganism intrusion human body, be prevention respiratory tract
The prevalence of infectious disease, the effective means for protecting personnel health.Related researcher studies discovery and adheres to wearing mouth mask by inquiry
Can reduce the infection of influenza, and many countries are in flu outbreak, using deposit protective mask as Non-medicine intervention means
To control the propagation of pathogenic microorganism.Anti-bacterium haze-proof mask increasingly table in terms of disease, reply burst biological pollution event is reduced
Reveal irreplaceable important function.
From 2004, since two scientists of University of Manchester are successfully separated out graphene, graphene, which already turns into, to be ground
The focus and focus studied carefully, in recent years, scientist find that graphene can not only be cut by the insertion to bacterial cell membrane,
Can also be by directly being extracted to the extensive of phospholipid molecule on cell membrane, to destroy cell membrane so as to killing bacterium, except this it
Outer its can reach 2620m because of its theoretical specific surface area2/ g, is a kind of potential sorbing material, can be at the dust-proof aspect of anti-haze
Play a role.
Nano silver particles can adhere to cell membrane surface and penetrate into bacterium, with containing in bacterial membrane in cell
The protein interaction of sulphur, when Nano silver grain enter bacterial cell formation one small-molecular-weight region bacterium center,
The bacterium group cluster.Particle attacks respiratory chain, cell division so as to ultimately result in cell death.The nanometer in bacterial cell
Particle discharges silver ion, so as to improve its bactericidal activity.Due to the larger specific surface area of nanoparticulate carriers and high table
Face activity, antiseptic can be contacted fully with bacterium, and the usage amount of antiseptic can be reduced, so silver system nano antibacterial agent is in antibacterial
Persistently, broad spectrum activity, high temperature resistant, without resistance, be not easily decomposed, many aspects such as safety and sanitation and efficiency height have great improvement,
Its anti-microbial property is better than classical antibacterial agents, can be widely applied to the antimicrobial treatment of textile, plastics, coating, water process, ceramics etc.
In.
Anti-bacterium haze-proof mask that current market is used or Patents report is in order to reach antibacterial, the purpose of anti-haze, mouth
Cover is generally made up of, and many more manipulations prepare anti-biotic material, mouth prepared by such mode clothes such as the gauzes or cotton of multilayer
Cover adds that respiratory resistance, complex procedures, cost are higher, and antiseptic due to the plyability with substrate it is not good enough, it is easily de-
Fall.Therefore, in the urgent need to a kind of preparation method is simple, dust better performances are adsorbed, antibacterial, deodorization are excellent, and for easy
It can also play the gauze mask of good isolation effect to expire in the infectiousness germ by media transmissions such as air and virus
Sufficient market needs.
The content of the invention
