Abstract
The invention discloses a replaceable film filter core for a PM2.5 purifying mouth mask and a preparation method of the filter corer. The replaceable film filter core for the PM2.5 purifying mouth mask comprises a first spunbonded nonwoven fabric layer, a melt-blown nonwoven fabric layer, a PTFE (Polytetrafluoroethylene) microporous film layer, an activated carbon nonwoven fabric layer and a second spunbonded nonwoven fabric layer which are combined from top to bottom successively. The film filter core has the beneficial effects that the small aperture and high porosity of a polytetrafluoroethylene microporous film is utilized, and the polytetrafluoroethylene microporous film is compounded with other layers, through multi-layer filtration and adsorptive action, the object of preventing PM2.5 particles from entering a human body is effectively achieved. The film filter core is a thin sheet piece, is extremely light, long in useful service life, good in PM2.5 particle preventing effect, good in air permeability, and designed to be replaceable in use, saves resources, has characteristics conforming to environmental requirements, and is worthy of being produced and popularized.
Description
Technical field
The present invention relates to a kind of purification PM2.5 mouth mask with replaceable overlay film filter core and preparation method thereof.
Background technology
This year, along with dense haze weather has appearred continuing in a plurality of provinces and cities of China, and national pay attention to day by day to environmental protection, " ambient air quality " of new revision also increased the PM2.5 monitoring index.These all make people more and more pay close attention to " PM2.5 ".
PM, English full name is particular matter, is particle.PM2.5 refers to that diameter in the atmosphere is less than or equal to the particle of 2.5 μ m, is also referred to as and can goes into the lung particle.Its particle diameter too small be difficult for stopped by respiratory tract, can directly enter bronchus and alveolar after being inhaled into human body, disturbs the gas exchange of lung, and causes other diseases.Simultaneously the PM2.5 particle diameter is little, its surface easily be rich in a large amount of poisonous, harmful substances and the time of staying in atmosphere long, fed distance is far away, thereby human body is caused the threat of multiple health.
Be accompanied by the rapid growth of China's economy, the higher objective reality that become of PM2.5 granule density value in many regional air, pollution for reply PM2.5, the common people have shown great enthusiasm to mouth mask, but the special mouth mask that protects at this superfine particle is also few in the market, the existing mouth mask overwhelming majority is to use nonwoven, gauze, plastics screen cloth etc. to be prepared from the market, they knit the hole or mesh is all bigger, the particle that some are tiny or flue dust can also pass mouth mask and enter nasal cavity.
Summary of the invention
The purpose of this invention is to provide a kind of purification PM2.5 mouth mask with replaceable overlay film filter core and preparation method thereof.Main purpose of the present invention will solve exactly that present common gauze, non-woven fabrics gauze mask are relative with plastic wire lint face mask gap excessively can't to stop the PM2.5 particle, utilize the small-bore of microporous teflon membran, realize intercepting the purpose that the PM2.5 particle enters human body effectively, filter core of the present invention can also absorbed air in toxic gas, remove peculiar smell, allow the people breathe high-quality air.
For solving the problems of the technologies described above, technical scheme of the present invention is:
A kind of purification PM2.5 mouth mask is composited by the first spun-bonded non-woven fabrics layer, melt-blown nonwoven layer of cloth, PTFE microporous film layers, activated carbon non-woven layer of cloth and the second spun-bonded non-woven fabrics layer from top to bottom successively with replaceable overlay film filter core.
The invention described above mouth mask is with replaceable overlay film filter core, during use, outside the first spun-bonded non-woven fabrics course, near air; The second spun-bonded non-woven fabrics layer, inwardly, near population.The PTFE microporous film layers refers to the microporous teflon membran layer.
The present invention's first spun-bonded non-woven fabrics mainly plays protection filter core and the first heavy filtration effect; The in-depth filtration of melt spraying non-woven fabrics plays the second heavy filtration effect; The PTFE microporous barrier plays the more filtration of deep layer; Active carbon nonwoven fabric then can be realized further separating fines and removing peculiar smell by absorption, and the second spun-bonded non-woven fabrics layer can play further filtration.
In order to improve the filter efficiency of filter core, guarantee its air penetrability simultaneously, the grammes per square metre of the first spun-bonded non-woven fabrics layer, melt-blown nonwoven layer of cloth, activated carbon non-woven layer of cloth and the second spun-bonded non-woven fabrics layer is 20～30g/m
2The grammes per square metre of PTFE microporous barrier is 1.0～4.0g/m
2The pore size of PTFE microporous barrier is 0.1～1.0 μ m, and porosity is 80～90%, and air penetrability is 8～14cm/s.
Above-mentioned air penetrability is what measure under 127Pa.
Daily required in order to satisfy, purification PM2.5 mouth mask is rectangle with the cross section of replaceable overlay film filter core, and long is 105-115cm, and wide is 75-85cm.
Above-mentioned purification PM2.5 mouth mask closes and forms with the manufacture method of replaceable overlay film filter core, the first spun-bonded non-woven fabrics layer, melt-blown nonwoven layer of cloth, PTFE microporous film layers, activated carbon non-woven layer of cloth and the second spun-bonded non-woven fabrics layered suture that utilize hot melt tape edge technology that order is stacked.
In order to improve the intensity of stitching, the temperature of hot melt tape edge is 105～180 ℃, and hot melt pressure is 0.2～0.8MPa.
The technology that the present invention does not specify is prior art.
Overlay film filter core of the present invention utilizes small-bore, the high porosity of microporous teflon membran, and it and other layers is composite, by multiple filtration and suction-operated, realized effectively intercepting the purpose that the PM2.5 particle enters human body, and the overlay film filter core is pieces of sheet, very light, Acceptable life is long, prevents the effective of PM2.5 particle, good permeability, and be replaceable use design, economize on resources, the characteristic of compliance with environmental protection requirements is worth producing and promoting.
