Description
Technical field
The present invention relates to haze-proof mask technical fields, more particularly to a kind of anti-haze of the composite nanometer filter based on graphene oxide
Antibacterial bacteriostatic mask and preparation method.
Background technique
In recent years, the owning amount of China's automobile rapidly increases and industrialized high speed development, causes air quality to deteriorate, mist
Haze day duration is increasingly longer, continues haze weather and causes extremely serious influence to human health and daily life,
And thus cause various diseases, comprising: the respiratory diseases such as asthma, respiratory tract infection, pulmonary infection, it is strong to the body of people
Health, group especially weaker to immunity such as children and the elderlys cause extremely serious influence.
City poisonous particles source: vehicle exhaust, the car using diesel oil are discharges fine particle " major criminal ", are used
Although what the compact car of gasoline discharged is gaseous pollutant, such as nitrogen oxides etc., the greasy weather is run into, is also easily converted to two
Secondary particulate pollutant aggravates haze；The exhaust gas of industrial production discharge, such as metallurgy, kiln and boiler, electromechanical manufacturing industry, also
A large amount of Automobile Services spray paintings, production of construction materials kiln burning and exhausting exhaust gas；The fugitive dust etc. that construction site and road traffic generate, can all add
Heavy fog haze, PM2.5 are commonly called as haze, also known as fine particle, have become one of the index that existing social stage people pay close attention to the most,
It can be suspended in the air long period, and content concn is higher in air, and it is more serious just to represent air pollution, therefore, open
Sending out filtering material high performance is one of effective measure.
Method of electrostatic spinning is the new development of chemical fibre conventional solution dry spinning and melt spinning, is current nanofiber
Equal superfine fibres manufacture most important method.There is apparent difference with traditional method, it is by polymer solution or melt band
Upper thousands of to up to ten thousand volt high-pressure electrostatics.The core of this technology is to make electrically charged polymer solution or melt in electrostatic field
Flowing and deformation, when electric field force is sufficiently large, polymer drop can overcome surface tension to form injection thread.Then it is steamed through solvent
Hair or melt are cooling and solidify and obtain fibrous material, therefore this process is known as electrostatic spinning.Existing Static Spinning nanometer film
Material, especially electrostatic spinning fiber film-strength is low, and the electrospinning film for preparing high areal density lacks economy, therefore uses merely
It is unable to reach its optimum filtration effect when nano-sized membrane is used as filtering material and functionality is poor.In addition, being knitted with routinely non-
It makes fiber filtering to compare, electrostatic spinning nano fiber film is that the mechanical strength of the filtering material of substrate is very low, therefore, by nanofiber
It is compound with non-woven cloth, it can both guarantee the mechanical strength and filtering property of filtrate, and can also reduce production cost.
Electrostatic spinning nano fiber diameter is thin, large specific surface area, is shown by this fibroplastic non-woven cloth excellent
Absorption property can be used as adsorbing medium, cladding active carbon, biocide etc., with these fiber applications in mask or air mistake
Filter membrane, can efficiently filter and the pernicious gas in air of degrading.
To hide haze pollution, mask becomes the preferred article of common citizen.But mask product currently on the market is big
Part cannot filter PM2.5, and the test result of the Chinese Consumers' Association in 2014 shows that only only a few external product reaches
Removal efficiency requirement, and these products are designed for industrial production, comfort, aesthetics be difficult to meet civilian want
It asks, for wearer when being carried out air-breathing using these masks and being exhaled, the inside and outside exchange velocity that on the one hand will lead to air is slower, makes
Insufficient feeling is supplied at wearer, another aspect expiration gas residence time on the inside of mask is long, and humidity is larger, influences face
Skin health.
