Description
Technical field
The present invention relates to antibacterial mask technical field, particularly relate to anti-haze mouth mask of a kind of antibacterial green based on graphene oxide and preparation method thereof.
Background technology
In recent years due to the quickening of process of industrialization, the aggravation of various pollution, the environment of human survival is constantly worsened, the potential intrusion chance of virus spread, germ increases, and the feature that respiratory infectious disease has the wide incidence of disease of the fast Susceptible population of spread speed high by the spittle and air borne causes very large threat to public health and social stability; Simultaneously China's haze weather to a certain degree that had a lot of city all to occur, PM2.5 is medically referred to as pellet, be the pollutant that Atmospheric Grains diameter is less than or equal to 2.5 microns, it is poor that mouth mask general on the market at present filters PM2.5 effect, effectively can not stop PM2.5.Wear protective mask can effectively filter PM2.5 particle, block pathogenic microorganism invade human body, be preventing respiratory infectious disease popular, protection personnel health effective means.Related researcher studies by inquiry and finds to adhere to wearing the infection that mouth mask can reduce influenza, and many countries are when flu outbreak, deposit protective mask is controlled the propagation of pathogenic microorganism as the means of Non-medicine intervention.Anti-bacterium haze-proof mask day by day shows irreplaceable important function in minimizing disease, reply burst biological pollution event.
From 2004, since University of Manchester two scientists successfully isolate Graphene, Graphene becomes focus and the focus of research already, in recent years, scientist finds that Graphene not only can by cutting the insertion of bacterial cell membrane, by the extensive directly extraction of phospholipid molecule in cell membrane, can also destroy cell membrane thus kill bacterium, in addition it can reach 2620m because of its theoretical specific surface area
2/ g is a kind of potential sorbing material, can play a role in anti-haze is dust-proof.
Nano silver particles can adhere to surface of cell membrane and penetrate in bacterium, with the protein interaction of sulfur-bearing in bacterial membrane in cell, when Nano silver grain enters the center that bacterial cell forms a small-molecular-weight region bacterium, this bacterium group cluster.Particle attacks respiratory chain, cell division thus finally cause cell death.In bacterial cell, this nano particle discharges silver ion, thus improves its bactericidal activity.The specific area larger due to nanoparticulate carriers and high surface-active, antiseptic can fully contact with bacterium, the use amount of antiseptic can reduce, so silver system nano antibacterial agent antibacterial lasting, broad spectrum activity, high temperature resistant, without resistance, not easily decomposition, safety and sanitation and efficiency high a lot of in had great improvement, its anti-microbial property is better than classical antibacterial agents, can be widely used in the antimicrobial treatment of textile, plastics, coating, water treatment, pottery etc.
Anti-bacterium haze-proof mask that is that current market uses or Patents report is in order to reach the object of antibacterial, anti-haze, mouth mask is made up of the cloth such as gauze or cotton of multilayer usually, and many more manipulations prepares anti-biotic material, mouth mask prepared by such mode adds respiratory resistance, complex procedures, cost are higher, and antiseptic is good not due to the plyability with substrate, easily comes off.Therefore, simple in the urgent need to a kind of preparation method, attract dust better performances, antibacterial, deodorization is excellent, and also can play the gauze mask of good isolation effect to meet market demand for easily through the vector-borne infectiousness germs such as air and virus.
Summary of the invention
The technical problem to be solved in the present invention be high for current existing mouth mask cost, preparation section is complicated and antiseptic due to the plyability with substrate good not, easily come off, the effect of due attract dust, antibacterial, deodorizing can not be played, there is provided a kind of preparation method simple, attract dust better performances, antibacterial, deodorization is excellent, and also can play the gauze mask of good isolation effect for easily through the vector-borne infectiousness germs such as air and virus.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
