Description

The anti-haze antibacterial bacteriostatic mouth mask of composite nanometer filter and preparation method based on graphene oxide
Technical field
The present invention relates to haze-proof mask technical field, the anti-haze of more particularly to a kind of composite nanometer filter based on graphene oxide Antibacterial bacteriostatic mouth mask and preparation method.
Background technology
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 more and more long, continues haze weather and causes extremely serious influence to human health and daily life, And thus trigger various diseases, including:The respiratory diseases such as asthma, respiratory tract infection, pulmonary infection, the body to people is good for Health, colony particularly weaker to immunity such as children and the elderlys, causes extremely serious influence.
City poisonous particles source:Vehicle exhaust, is discharge fine particle " major criminal " using the car of diesel oil, is used Although the compact car discharge of gasoline is gaseous contaminant, such as nitrogen oxides etc. runs into the greasy weather, is also easily converted to two Secondary particulate pollutant, aggravates haze;The waste gas of industrial production discharge, such as metallurgical, kiln and boiler, electromechanical manufacturing industry, also A large amount of Automobile Service spray paintings, the waste gas of production of construction materials kiln burning and exhausting;Airborne dust that construction site and road traffic are produced etc., can all add Heavy fog haze, PM2.5 is commonly called as haze, is also called fine particle, one of index paid close attention to the most as existing social stage people, It can be suspended in air long period, its in atmosphere content concn it is higher, it is more serious just to represent air pollution, therefore, open It is one of effective measure to send out filtering material high performance.
Method of electrostatic spinning is the new development of chemical fibre conventional solution dry spinning and melt spinning, is current nanofiber Topmost method is manufactured Deng superfine fibre.There is obvious 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 steamed through solvent Hair or melt cooling and solidify and obtain fibrous material, therefore this process is referred to as electrostatic spinning.Existing Static Spinning nanometer film Material, especially electrostatic spinning fiber film low intensity, and the electrospinning film shortage economy of high areal density is prepared, therefore using simple Its optimum filtration effect is unable to reach when nano-sized membrane is used as filtering material and feature is poor.Knitted additionally, non-with routine Make fiber filtering to compare, electrostatic spinning nano fiber film is very low for the mechanical strength of the filtering material of base material, therefore, by nanofiber It is compound with non-weaving cloth, can both ensure the mechanical strength and filtering property of filtrate, can also reduce production cost.
Electrostatic spinning nano fiber diameter is thin, specific surface area big, is shown by this fibroplastic non-weaving cloth excellent Absorption property, can be used as adsorbing medium, cladding activated carbon, biocide etc., with these fiber applications in mouth mask or air mistake Filter membrane, can efficiently filter and the pernicious gas in air of degrading.
To hide haze pollution, mouth mask turns into the first-selected article of common citizen.But, mouth mask product in the market is big Part can not 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 product major parts be for industrial production is designed, comfortableness, aesthetic property be difficult to meet it is civilian will Ask, on the one hand wearer can cause the inside and outside exchange velocity of air slower when being carried out air-breathing and being exhaled using these mouth masks, make Into the sensation that wearer's supply is not enough, another aspect expiration gas residence time on the inside of mouth mask is long, and humidity is larger, influences face Skin health.
