Description
Technical field
The present invention relates to a kind of mouth mask filtering material and preparation method thereof, particularly relate to a kind of mouth mask polymer nanofiber filtering material and preparation method thereof.
Background technology
Rapidly, people's living standard significantly improves in current world economy development.But while economic development, also bring severe environmental problem.The respiratory health impact of residue on people of the discharge through burning in the processes such as industrial production, daily generating, motor vehicle exhaust emission is huge.Especially in air, diameter is less than the fines thing (PM 2.5) of 2.5um, and they are the maximum arch-criminals causing air haze and Human Lung Cancer.On February 29th, 2012, Premier Wen Jiabao holds Executive Meeting of the State Council, and agree to " ambient air quality " of issuing new revision, regulation includes PM 2.5 in each province and city compulsory test category.
Current mouth mask filtering material, the filter materials such as mainly traditional nonwoven fabric non-woven fabrics fiber or rubber and plastic, these materials prepare mouth mask dust-proof effect difference or permeability poor.Such as Chinese utility model patent (ZL02232615.4) describes a kind of anti-dust respirator, and its filtering material adopts filter paper, makes this mouth mask there is poor air permeability, uncomfortable shortcoming.Chinese utility model patent (ZL 03253526.0) describes a kind of novel anti-dust respirator, but the filtering material quality that its mouth mask uses is large, and its dust-proof effect is also undesirable.
Polymer nanofiber is that diameter arrives the superfine fibre of hundreds of nanometer tens, is prepared by electrostatic spinning technique.Electrostatic spinning be make Polymer Solution or melt charged, and the high voltage electric field be placed between spinning nozzle and receiving screen, the surface tension of Polymer Solution or melt is overcome by electrostatic attraction, thus make spinning solution become one charged injection stream, and move in the electric field, be finally collected on metal net shaped receiving screen, become the fibrofelt of nonwoven cloth-like, Polymer Solution or melt solidify because of the evaporation of solvent or melt cooling, thus become nano fiber non-woven and weave cotton cloth.The bonded fabric of the nanofiber of this static electrification own is a kind of extraordinary filtering material, to the filter efficiency of fines is high and gas permeability is excellent.
Therefore, those skilled in the art is devoted to develop the high and mouth mask that gas permeability is excellent of a kind of filter efficiency.
Summary of the invention
Because the above-mentioned defect of prior art, technical problem to be solved by this invention is to provide one both effectively can filter fines, had again the mouth mask filtering material of superior ventilation property.
For achieving the above object, the invention provides a kind of mouth mask polymer nanofiber filtering material and preparation method thereof.
On the one hand, the invention provides a kind of mouth mask polymer nanofiber filtering material.
Particularly, mouth mask polymer nanofiber filtering material of the present invention comprises polymer nanofiber and supporter non-woven fabrics.Wherein, the weight ratio of polymer nanofiber and supporter non-woven fabrics is 10-30: 100.
Mouth mask filtering material of the present invention is the composite membrane of polymer nanofiber and supporter non-woven fabrics, wherein, the thickness of the polymer nanofibre film of filtration can be very thin, and its fibre diameter size is also controlled, thus while ensureing that it is to particulate rejection, also there is excellent permeability.
In the specific embodiment of the present invention, the thickness of polymer nanofibre film is preferably 1-30um, and the polymer nanofiber diameter in this rete is preferably 300-1000nm, and fiber is random arrangement substantially.
In mouth mask filtering material of the present invention, described polymer nanofiber is preferably polyether sulfone (PES), Kynoar (PVDF), polyurethane (PU), polyamide (PA), polyacrylonitrile (PAN), polystyrene (PS), polyvinyl alcohol (PVA), PLA (PLA), PETG (PET), polyethylene (PE) or polypropylene (PP).
Described supporter non-woven fabrics is melt-blown, spunbond or needle punched non-woven fabrics preferably.
On the other hand, present invention also offers a kind of method preparing above-mentioned mouth mask filtering material, comprise the steps:
First, by polymer nanofiber and the blended dissolving of solvent, stable uniform solution is obtained; Or directly by polymer nanofiber melting, obtain homogeneous melt;
Then, polymer nanofiber is spun on supporter non-woven fabrics by electrospinning process by above-mentioned uniform solution or homogeneous melt, thus obtains mouth mask filtering material.In obtained mouth mask filtering material, the weight ratio of polymer nanofiber and supporter non-woven fabrics is 10-30: 100.
In a preferred embodiment of the invention, during by polymer nanofiber and solvent blended dissolving, the weight ratio of polymer nanofiber and solvent is 10-32: 100.
In the present invention, described solvent is preferably one or more in DMF, 1-METHYLPYRROLIDONE, DMA, acetone, water, ethanol, dichloroethanes, trichloroethanes.
In the present invention, described electrospinning process is the common method that this area manufactures nanometer and superfine fibre, is not particularly limited this.Such as by solution or melting electrostatic spinning method polymer nanofiber spun solution or melt spins on supporter non-woven fabrics.
The invention still further relates to a kind of mouth mask containing above-mentioned filtering material.
Because the diameter of polymer nanofiber contained in filtering material and the thicknesses of layers of nanofiber can regulate and control, therefore, mouth mask filtering material of the present invention can retain particulate effectively, possesses again excellent permeability.At the same time, also the rejection of this filtering material and the change of Pressure Drop is regulated and controled by the control diameter of polymer nanofiber and the thicknesses of layers of nanofiber.
The preparation method of mouth mask filtering material of the present invention is simple, with low cost, is applicable to suitability for industrialized production.Prove through test, the mouth mask be made up of mouth mask filtering material of the present invention, not only have excellent gas permeability, and can efficiently retain sodium chloride aerosol particle, the rejection of mouth mask filtering material of the present invention to the sodium chloride aerosol particle of 0.3um can up to more than 90% after tested.When Pressure Drop is less than 35mm water column, this mouth mask can reach the use standard of Chinese GB2626-2006KN90.
