Description
Technical field
The present invention relates to medical product field, be specifically related to a kind of mouth mask solid type electrostatic spinning filtering material and preparation method thereof.
Background technology
Along with China's sustain economic high speed development, urbanization and process of industrialization are accelerated day by day, and various atmosphere pollution sharply increases.The atmospheric environment problem that developed country constantly occurs in upper century-old evolution, now concentrated in China and emerged in large numbers, the January of 2013 has become the numerous city of China and has comprised the big city months that over 50 years, haze weather is maximum such as Guangzhou, Beijing and Shanghai Wuhan.At present, the major pollutants affecting China's urban air-quality are fine particles of particle diameter < 2.5 microns floating in air, and the health of people in serious threat.
Current mouth mask is on the market made up of materials such as single or multiple lift cotton, gauze, non-woven fabrics or Polypropylence Sheets mostly, these mouth masks can only retain larger particulate matter, as Du Jian etc. points out in " research of medical protective mask protection efficiency and wear time ", 12 layers of gauze filter material only have 32.3% for the filter efficiency of 0.3 micron particles, and 24 layers of gauze are then also only 43.9%.90,95 even more than 99 can be reached as its filter efficiency of mouth mask of filter material by melt spraying non-woven fabrics, but gas permeability is not good, wearing comfort is poor, if go out guild as daily haze weather to use inconvenience, especially the elderly, children or person in poor health should not use especially.
Electrostatic spinning is a kind of important method manufacturing superfine fibre, particularly adopt filter material prepared by organic polymer electrostatic spinning, there is light weight, filter that suction-operated is strong, good permeability, to pellet rejection highs such as PM2.5, thus this method has started to be used in the mouth mask filtering material field that research can retain PM2.5.
Patent CN102872654 A and patent CN 102920067 A discloses the mouth mask using Electrospinning preparation can retain PM2.5, but, the high molecular polymer itself used due to it and its prepare the organic solvent that electrostatic spinning adopts all there is certain toxicity, there is no volatilization after spinning and remain solvent in the fibre and will wear in process people and discharge gradually thus affect the health of people; Simultaneously, the high molecular micro nanometer fibre diameter prepared due to electrostatic spinning is little, spin by hydrophilic high molecular polymer the fiber obtained and can wear in process because of human body the steam effect generation micro dissolution being subject to characteristics of contaminated respiratory droplets, the duct of filtration is caused to narrow or block, thus or increase respiratory resistance, or reduce the interception capacity of PM2.5.
Chinese patent CN102872654A, Chinese patent CN102920067A and CN2884939Y, disclose and use Electrospinning to prepare mouth mask and mouth mask filter membrane material, but these patents are not good for the rejection effect of the pellets such as PM2.5, and all only relate to the spinning of planar film.And should be 3-D solid structure from ergonomics angle mouth mask, therefore also need further processing and fabricating just can be made mouth mask shape.But because polymerizable material intensity is usually poor, be processed into the obstruction or local gas leakage that cell channels in mouth mask process, can be caused unavoidably, thus causing mouth mask respiratory resistance to increase, or reducing the phenomenons such as filter efficiency.Study display in addition, the actual protection effect when height of filter material efficiency can not reflect that mouth mask is worn, also relevant with people face closed intensity with mouth mask shape.
Chinese patent CN103271466A discloses a kind of three-dimensional mask, be made up of the outer cover of filtering bodies and parcel filtering bodies, filtering bodies is made up of some rectangular-shaped risers, is connected between riser by gripper shoe, cross filter ruffle and then adopt polypropylene fibre melt spraying non-woven fabrics, also add two air intake duct filtered airs in addition.Described method improves the gas permeability of mouth mask from structure, but the preparation method of this invention and usual method are all very complicated, and this patent just refer to the effect can protecting PM2.5, and the data of concrete filter efficiency and gas permeability are not supported.
For protection people's health, reduce the various diseases because air pollution causes, be badly in need of that a kind of filter effect is excellent, good permeability, safe and reliable, be applicable to various crowd and use, make again simultaneously simple, wear easy mouth mask.
Summary of the invention
In order to overcome above defect, the invention provides that a kind of filter effect is excellent, good permeability, safe and reliable, three-dimensional shape and people face closed intensity be high, making again the mouth mask that simply efficiently can retain the pellets such as PM2.5 and PM1.0 simultaneously.
For achieving the above object, technical scheme of the present invention is, a kind of mouth mask solid type electrostatic spinning filtering material, described mouth mask solid type electrostatic spinning filtering material is using non-toxic high molecular polymer P VB as matrix, adopt electrostatic spinning technique, use three-dimensional model to knit the just Static Spinning micro nanometer fiber film obtained as receiving system is disposable.
