Abstract
The invention discloses a polytetrafluoroethylene microporous composite membrane haze prevention mask. Bamboo carbon cloth is adopted as the outer surface layer, the polytetrafluoroethylene microporous composite membrane is adopted as the middle layer, a nanometer silver fiber fabric is adopted as the inner layer, a arch-shaped nose cushion made of memory foam material, the outer surface layer and the inner layer are tailored and sealed into a three-dimensional body, and the middle layer is folded into a three-dimensional body instead of being tailored. The mask is high in air permeability and low in ventilation resistance, can filter out bacteria and fine particulate matter with the diameter larger than 0.45 micron or 1.0 micro in air, plays a role in bacteria removal and haze prevention, and plays a role in toxin prevention, mildew prevention and odor prevention, and the dust removal effective rate can reach more than 95%.
Description
Technical field
The invention belongs to small stores, be specifically related to the anti-haze mouth mask of the laminating film of a kind of polytetrafluoroethylene (PTFE) (PTFE) micropore.
Background technology
Anti-haze mouth mask is widely used in protection human respiratory by crowd and avoids being suspended in that the fine particles such as airborne PM2.5 suck lungs and the atmosphere pollution occasion that works the mischief; anti-haze mouth mask has two types conventionally comprehensive analysis in filtering efficiency and this two large factor situation of ventilation efficiency; be the common anti-dust respirator that venting capability is good, another kind is the good industrial anti-dust mouth mask of filtering efficiency.Although aeration when common anti-dust respirator is worn as cotton yarn mouth mask, non-woven fabrics gauze mask, active carbon mask etc. is good, its filtering efficiency to fine particle is very poor, without obvious anti-haze effect; Although another kind of as KN90, other industrial anti-dust mouth mask of N95 level have reached the dustproof requirement of filtering most of fine particles in industrial production, because aeration resistance is large, gas permeability is poor, and is not suitable for the common people in the anti-haze use of daily life occasion; The anti-haze mouth mask that also has a kind of more renew cartridge, although the filtering efficiency of material for core is higher, but because filter core area causes by the gas flow of filter element filtering less compared with little, filter core periphery position Air permenbility is large and form gas leakage effect in addition, therefore its anti-haze effect is undesirable.The patent of invention of Minnesota Mining and Manufacturing Company " flat-folded personal respiratory protection equipment and manufacturing process thereof " for example; the 9010 type N95 particle protective masks of producing are disposable technical grade anti-dust respirators; it strengthens interception dust ability with the hole that thickening encryption non-weaving cloth method is dwindled between fiber; but poor because of less its gas permeability that causes of the thicker and mutual hole of fibre diameter of non-weaving cloth, wear for a long time and can allow people feel unsmooth breath.

The microstructure of microporous teflon membran: the netted microcellular structure that 1. PTFE microporous barrier surface has is the hole forming by between each microfibre, and microfibre orientation is substantially parallel with draw direction.Many microfibres tangle and are connected to form node, and the microfibre Breadth Maximum connecting mutually between node is less than 0.1 μ m.2. PTFE microporous barrier belongs to asymmetric membrane, and the positive and negative pore size of film is variant, and cross section pore size is larger than its surperficial pore size, and longitudinally pore size is greater than laterally.3. the cross section of PTFE microporous barrier is a kind of network structure, has the complicated variations such as netted connection, hole edge cover, duct bending in the three-dimensional structure in hole.Artificial synthetic macromolecular material microporous teflon membran has very stable chemistry, thermal property, nontoxic, without irritated, nonirritant, filtering is quickly and effectively greater than fine particle and the bacterium of PTFE microporous barrier micropore size, the effect that play the anti-haze of degerming, purifies air.
The refinement honeycomb microporous structure running through inside and outside bamboo charcoal has, uses the micronized bamboo charcoal of nanometer technology (nano bamboo micro mist) to make bamboo-carbon fibre with polyester melt spinning.The fine and closely woven porous of this fiber, high adsorption capacity, its adsorption capacity is the more than 10 times of same volume charcoal, therefore contained mineral matter is the more than 5 times of same volume charcoal, has the function of good deodorizing, anticorrosion, absorption peculiar smell.Nano bamboo material also have good antibacterial, sterilization, absorption and in and the contained acidic materials effect of sweat, also there is the several functions such as far infrared, anion, heat accumulation thermal, the function of bamboo-carbon fibre has permanent, is not subject to the impact of washing times.
Bamboo charcoal specific area is the more than 3 times of charcoal, and its Porous compact texture can be brought into play the effect of absorption, decomposition peculiar smell and smelly eliminating to harmful chemicals such as sulfide, nitride, methyl alcohol, benzene, phenol.
Active carbon is a kind of carbide of multiple aperture, there is profuse hole structure, there is good characterization of adsorption, can be in its Adsorption on Surface gas, liquid or colloidal solids, the specific surface that has that every gram of active carbon has is equivalent to 1000 square metres more than, the quality of adsorbent can approach the quality of active carbon itself, be specially adapted to the occasion that contains the irritative gas such as organic gas, acid volatile matter, agricultural chemicals, sulfur dioxide, thereby active carbon mask has the effects such as gas defence, deodorizing, bacteriological filtration, resistance dirt, and be widely used.
Selecting bamboo carbon cloth is that to take high-quality ultra micro bamboo charcoal fine grained be raw material, with automatic control type thermal fusing powder point, shifting compounding machine is coated in bamboo charcoal powder on nonwoven or other base material and the composite of making, bamboo carbon cloth has good adsorption-decomposition function ability and releasing far infrared and produce anion effect, select bamboo-carbon fibre cloth as the extexine of mouth mask can play that the gas defence to air when mouth mask is worn is removed the evil, damping mildew-resistant, antibacterial, worm-expelling, deodorizing disappear the multiple efficacies such as peculiar smell.
Nano silver fibre is to take chemical fiber, cotton fiber by blazoning formula nanometer, to implant silver-plated technology as matrix, and silver ion and fiber are combined into one securely.Have antistatic, shielding property, there is powerful antibacterial and deodouring function: argent ion has very high biologically active in the environment of warm moist, make the inside and outside protein coagulating of bacterial cell membrane, the breathing reproductive process of blocking-up bacterial cell, the environment more activity of warm moist silver ion is stronger, can rapidly ammonia be oxidized to bacterium and rotten protein adsorption on it and reduce or eliminate stink, select nano silver fibre fabric can play when mouth mask is worn characteristics of contaminated respiratory droplets gas and the saliva spittle played to mildew-resistant deodorizing as the endonexine of mouth mask, the multiple effect such as antibiotic health.
The invention provides the anti-haze mouth mask of the laminating film of a kind of polytetrafluoroethylene (PTFE) (PTFE) micropore, extexine adopts bamboo carbon cloth, intermediate layer adopts the laminating film of polytetrafluoroethylene (PTFE) micropore, endonexine adopts nano silver fibre fabric, adopt the arch-shaped nose pad of memory foam material, extexine and endonexine are cut out involution for three-dimensional, intermediate layer is not for cutting out, by being folded into solid, there is highly-breathable, low aeration resistance, in can filtering air, diameter be greater than bacterium and the fine particle of 0.45 μ m to 1.0 μ m, plays the anti-haze effect of degerming, and dedusting is efficient to be reached more than 99%.And there is gas defence, mildew-resistant, deodorization.
