Abstract

The invention relates to a health-care material for preventing PM2.5 particles. The health-care material comprises four layers totally, i.e., mixed extracting solution non-woven cotton fabric, a polytetrafluoroethylene filtering membrane, an active-carbon fiber felt and a non-woven fabric material which are arranged in sequence from inside to outside, wherein the four edges of the health-care material are closed by a sewing mode. At every layer, different harmful substances possibly invading into a human body are blocked in a layer-by-layer manner, so that the respiratory system of the human body is protected. As a material, the health-care material can be widely applied in multiple fields such as masks and protective clothing and the like.

Description

A kind of for preventing the health-care material of PM2.5 granule

Technical field

The present invention relates to field of material technology, specifically, relate to a kind of for preventing PM2.5 granule from sucking, it is possible to the material of protection respiratory system。

Background technology

Haze weather is a kind of atmospheric pollution state, haze is the general statement to suspended particulate substance content overproofs various in air, and especially PM2.5 (the equivalent aerodynamic diameter particulate matter less than or equal to 2.5 microns) is considered as " arch-criminal " that cause haze weather。The aerosol systems that mist is made up of the small water droplet being suspended in a large number in surface air or ice crystal。Come across autumn and winter season more, be the product of ground layer water in air vapour condensation。The existence of mist can reduce air transparency, makes visibility deterioration, if the horizontal visibility of object is reduced within 1000 meters, just the weather phenomenon of the condensation vapor thing being suspended in surface air is called mist。Haze, also can make air muddy also referred to as particles such as the dust in gray haze air, sulphuric acid, nitric acid, organic hydrocarbon compounds。The horizontal visibility of object is called mist or mist in this phenomenon of 1000-10000 rice。It should be saturated for forming atmospheric humidity during mist。The light of the mist scattering formed due to aqueous water or ice crystal is little with wavelength relationship, thus mist seems to be creamy white or Bluish white and Lycoperdon polymorphum Vitt。Sulfur dioxide, nitrogen oxides and pellet are mainly comprising of haze。

Along with the high speed development of industry in recent years, while driving China's economic level to improve, also it is further exacerbated by the deterioration of environment。Haze weather occurs again and again, scope is all shrouded Under the Dome by initial Jing-jin-ji region some areas are even to being extended to whole China nearly, and haze weather persistent period factor concentration increasingly longer, that scope is increasing, harmful is more and more higher, the health making people is deeply hurt, therefore, the measure strengthening people's resistance at present about reducing respiratory tract injury becomes the hot topic in society。

Now, although the protective device for protecting pm2.5 is many on market, but its specific performance is uneven, has and other even manufactures in a rough and slipshod way, does not only play the effect of health care protection, also jeopardized the health of the people in certain degree。Therefore, a kind of cost of invention is suitable, and purposes is relatively wide, and the material of health properties high-quality is extremely urgent。

Summary of the invention

It is an object of the invention to provide a kind of protective health material, be used for preventing PM2.5 granule from sucking, the respiratory system of protection human body, maintain healthy physique。

In order to realize object above, the technical solution used in the present invention is: a kind of for preventing the health-care material of PM2.5 granule, it is characterized in that, described material is provided with four layers altogether, from the inside to the outside successively by mixed extract nonwoven cotton, Teflon filtration film, active carbon fiber felt and nonwoven cloth material composition, four limits of described material are closed by sewing mode。

Further, the thickness of described active carbon fiber felt is 0.2～0.7mm。

Further, described Teflon filtration film thickness 5um～1Sum, porosity more than 85%。

Further, the extracting solution of described mixed extract nonwoven cotton is Cymbidium ensifolium (L.) Sw., violet, eucalyptus globolus mixed extract, and in extracting solution, Cymbidium ensifolium (L.) Sw., violet, eucalyptus globolus ratio are 1: 1～3: 1～3。

Beneficial effects of the present invention: innermost layer is mixed extract nonwoven cotton, the non-woven cotton that the Cymbidium ensifolium (L.) Sw. that adopts concentration to be 5～20%, violet, eucalyptus globolus mixed extract processed, Cymbidium ensifolium (L.) Sw. has suppression nerve to be overexcited, improve and breathe, eliminate nervous, treatment asthma, strengthen immunity, eliminate abnormal flavour, it is suppressed that the multi-efficiencies such as bacterial growth。Eucalyptus globolus flower can preventing respiratory tract infection, be suitable for rhinitis, asthma, treatment flu, remove nasal obstruction, dizzy。Gillyflower contributes to hypersensitive cough and pertussis, the problem being particularly suited for breathing aspect。Three of the above flower is escaping gas, enters human lung along with breathing, and plays improvement and breathes, preventing respiratory tract infection, and enhancing immunity reaches lung moistening and protects lung and improve the health care purpose of respiratory function。

Teflon filtration film thickness is 5um-15um, porosity more than 85%, and aperture can be controlled in about 0.2um, has the spy such as peel strength height, big, the even aperture distribution of Air permenbility。The efficiency of dust collection of Teflon filtration film, up to more than 99.99%, enough can filter out the dust granules of pm2.5, is current state-of-the-art air filting material in the world, so the haze air through this layer of filtration is abnormal clean。

Active carbon fiber felt has the character that absorption is wide, and capacity is big, to gasoline, aldehydes, phenols, alcohols, organic steams adsorbance specific activity charcoal (GAC) such as alkene are several times greater to tens times, inorganic gas have good adsorptivity (such as No, N, S, S, HF, HCL etc.), activated carbon fiber (ACF) is the new and effective adsorbing material surmounting activated carbon (GAC), is a kind of novel regeneration product。It has highly developed microcellular structure, and adsorption capacity is big, and desorption rate is fast, good purification。Through the filtration of this layer, the Organic substance in air is adsorbed complete substantially, medium-and-large-sized dust granules substantially completely without。

Outermost layer adopts the nonwoven cloth material processed through supercool catalyst sprinkling, the bulky grain dust in air can be filtered out, due to cold catalyst to the poisonous and harmful irritative gass such as the free formaldehyde in air, ammonia, TVOC can effective fast decoupled, therefore ground floor can dispose the poisonous and harmful irritative gass such as the big dust in air and formaldehyde, ammonia, TVOC。

To sum up, owing to the present invention is made up of four layers of unlike material, and each layer is both for the different harmful substances being likely to invade human body, protects through layer by layer, the respiratory system of human body has been protected。And the present invention is as a kind of material, it is possible to be widely used in the multiple fields such as mask, protective garment, so being suitable for being widely popularized。
