Description
Technical field
The invention belongs to technical field of environment protection equipment, it is related to air clearing product, particularly relates to a kind of high printing opacity
The preparation method of dustproof screen window material and screen window.
Background technology
With the development of industrial technology so that atmosphere pollution is increasingly severe, under the air quality of people's life is also serious
Drop, so that the life of people is also received and had a strong impact on, the especially appearance of haze weather.And suspended particulate substance is not in air
Disconnected increase is arch-criminal that haze weather occurs.On the basis of air quality can't be improved quickly, room air is improved
Quality becomes particularly necessary.And the exchange of indoor and outdoor air will be realized by window, set for some indoor air cleanings
It is standby, the purifying problem of air can not be solved from source, it is difficult to meet the demand of most of users.
The popular screen window that in the market occurs in currently available technology has common nylon, glass fibre, plastics and gold
Category braiding gauze etc., conventional gauze mesh size is about 20*20 mesh, and single mesh is 1.27mm*1.27mm, is mainly used to
Bulky grain thing is obstructed, but there was only 0~5% to PM2.5 intercepting efficiency.And the various anti-PM2.5 released on the market in recent years
Screen window, including milipore filter screen window, nanofiber screen window etc., there are to varying degrees airtight, translucency it is poor or
The problems such as PM2.5 intercepting efficiencies are less than 40%, and price is in 350~600 yuan/square meter, and also there is also have for nanofiber screen window
The shortcomings of low intensity, short service life.
The content of the invention
The present invention is in order to overcome the shortcomings of that prior art is present, in view of there is provided a kind of filter efficiency for the defect of existing screen window

The Surface mulch last layer screen cloth of fiber membrane carrier；
C, be thermally bonded under conditions of 50~300 DEG C of temperature, 0.1~20MPa of pressure, both nanometer screen material.
Nano fibrous membrane is made up of non-hydrophilic macromolecular fibre silk, and it is consolidated by the countless nanofiber long filaments freely disperseed
Change is bonded in what is formed on fiber membrane carrier, 100~1000nm nano-pore in the surface distributed of tunica fibrosa, porosity is
80~98%.The sprinkling of nanofiber long filament is realized by the mode of relative motion repeatedly of spinning head and reception device, spinneret
Head is to have syringe needle spinning head and any one in needle-less spinning head.
The even application mode of hot pressing glue microparticle is realized by way of electrostatic spraying is coated, electrostatic spraying voltage
For 10~70kV, jet length is 5~25cm, and injecting time is 15~60s.Screen window base material is that a kind of hard is punched or porous material
Material, the mesh number of screen cloth is 40~200 mesh, and the material of screen cloth is silk or synthetic fibers.
A kind of preparation that the high printing opacity PM2.5 nanofiber screen windows of erasable are prepared using high printing opacity dustproof screen window material
Method, screen window includes framework and the gauze being embedded in framework, and gauze is punched or porous material conduct using a kind of hard
Base material, substrate surface spinning nano fibrous membrane；The preparation method of screen window comprises the following steps：
A, electrostatic spinning solution being prepared first, tourmaline being added in spinning solution, it is molten that uniform spinning is made in stirring
Liquid, carries out electrostatic spinning；
B, the base fabric that has nano fibrous membrane will be spinned dry in the air at room temperature after 12~24h of system, then punched using clear hard
Or porous material carries out edge and internal local ultrasound adhesion process as drop cloth；
C, finally cut out after gauze in embedded framework screen window is made.
Clear hard perforated material is PET, PA, PU, PC or PS, and porous material is common nylon, braided metal silk, PVC
Or glass fibre gauze, a diameter of 0.1~1mm of the surface holes of clear hard perforated material or porous material.
Electrostatic spinning solution is used in polyacrylonitrile, Kynoar, nylon 6, nylon66 fiber, polystyrene, polyurethane
One or more, the high molecular polymer that electrostatic spinning solution is used is any water insoluble polymerization available for electrostatic spinning
The one or more of thing, the solvent that electrostatic spinning solution is used is high volatile solvent DMF, N, N- bis-
One or more in methylacetamide, formic acid, acetic acid, methanol, ethanol, acetone.
The tourmaline that mass percent is 0.1~5%, tourmaline are added in obtained homogeneous electrostatic spinning solution is prepared
The size of particle is 0.1~1.5 μm, and adds Polymer Solution in 40 DEG C of water-baths and stir 4~8h, is prepared into uniform
Spinning solution, carries out electrostatic spinning, and the spinning time is 2~5min, obtains a diameter of 100~300nm of nanofiber, Nanowire
The thickness for tieing up film is 15~25 μm.
The high transparent nano fiber Dustproof screen window prepared using high printing opacity dustproof screen window material of the invention includes framework
And it is embedded in the nanometer screen material in framework.Using heat bonding processing or local ultrasound adhesion process inside screen window, also may be used
Selectively handled according to the usable floor area of actual screen window, and clear hard punching or porous material surface erasable, material color
It is changeable, with dicoration.
The beneficial effects of the invention are as follows：, should the present invention relates to a kind of nanometer of screen material and the preparation method of screen window
Screen window has the advantages that intensity is high and service life is long simultaneously.The present invention can be prepared strong by selection, improvement spinning technique
It is dust-proof that degree height, service life length, nanofiber are evenly distributed, erasable, good decorating effect, transparency height, strainability are excellent
Screen material, its filter efficiency is 85~99%, and filtration resistance is 15~80Pa, and transparency is 80~95%, detachably, cleaning
It is convenient, and can be with turnup, with good market prospects.Compared with prior art, screen window of the invention can effectively anti-PM2.5
Deng fine particulates, and resistance is low, and air flow property is good, and wind resistance is excellent.In addition, the screen window easy to clean of the present invention, can be used
Dry and wet rag wipes out the dust on surface, and Acceptable life is detachable after 1 year, 1 year.
