Description
Technical field
The present invention relates to a kind of purification PM2.5 mouth mask replaceable overlay film filter core and preparation method thereof.
Background technology
In this year, along with multiple provinces and cities of China have occurred continuing dense haze weather, and country is to the pay attention to day by day of environmental protection, and " ambient air quality " of new revision too increases PM2.5 monitoring index.These all make people more and more pay close attention to " PM2.5 ".
PM, English full name is particularmatter, is particle.PM2.5 refers to that in air, diameter is less than or equal to the particle of 2.5 μm, also referred to as entering lung particle.Its particle diameter is too small not easily to be stopped by respiratory tract, can directly enter bronchus and alveolar after being inhaled into human body, the gas exchanges of interference lung, and causes other diseases.Simultaneously PM2.5 particle diameter is little, its surface be easily rich in a large amount of poisonous and harmful substances and time of staying in an atmosphere long, fed distance far, thus causes the threat of multiple health to human body.
Along with the rapid growth of China's economy, in many regional air, PM2.5 granule density value is higher becomes objective reality, for tackling the pollution of PM2.5, the common people show great enthusiasm to mouth mask, but carry out for this superfine particle the mouth mask that protects and few especially in the market, on market, the existing mouth mask overwhelming majority uses non-woven fabrics, gauze, plastic net cloth etc. to be prepared from, they to knit hole or mesh all comparatively large, some tiny particles or flue dust can also enter nasal cavity through mouth mask.
Summary of the invention
The object of this invention is to provide a kind of purification PM2.5 mouth mask replaceable overlay film filter core and preparation method thereof.Main purpose of the present invention will solve that current common gauze, non-woven fabrics gauze mask are relative with plastic net cloth mouth mask gap excessively cannot stop PM2.5 particle exactly, utilize the small-bore of microporous teflon membran, effectively realize intercepting the object that PM2.5 particle enters human body, filter core of the present invention can also toxic gas in absorbed air, remove peculiar smell, allow people breathe high-quality air.
For solving the problems of the technologies described above, technical scheme of the present invention is:
The replaceable overlay film filter core of 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.
The replaceable overlay film filter core of the invention described above mouth mask, during use, the first spun-bonded non-woven fabrics layer is outside, near air; Second spun-bonded non-woven fabrics layer, inwardly, near population.PTFE microporous film layers refers to microporous teflon membran layer.
The present invention 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; PTFE microporous barrier plays the filtration of more deep layer; Active carbon nonwoven fabric then realizes being separated fines further 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, ensure its air penetrability, 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 simultaneously
2; The grammes per square metre of PTFE microporous barrier is 1.0 ~ 4.0g/m
2; The pore size of PTFE microporous barrier is 0.1 ~ 1.0 μm, and porosity is 80 ~ 90%, and air penetrability is 8 ~ 14cm/s.
Above-mentioned air penetrability is measure under 127Pa.
In order to meet daily needed for, 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.
The above-mentioned purification PM2.5 mouth mask 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 order to be stacked close and form.
In order to improve the intensity of stitching, the temperature of hot melt tape edge is 105 ~ 180 DEG C, and hot melt pressure is 0.2 ~ 0.8MPa.
The not specified technology of the present invention is prior art.
Overlay film filter core of the present invention, utilizes the small-bore of microporous teflon membran, high porosity, and it and other layers is composite, by multiple filtration and suction-operated, have effectively achieved and intercept the object that PM2.5 particle enters human body, and overlay film filter core is pieces of sheet, very light, Acceptable life is long, anti-PM2.5 particle effective, good permeability, and be replaceable use design, economize on resources, meet the characteristic of environmental requirement, be worth producing and promoting.
