Description
Technical field
The present invention relates to a kind of efficient low-resistance nanometer anti virus mouth mask and production method thereof.
Background technology
Since atypical pneumonia outburst in 2003, research of anti-virus mouth mask and production have caused the extensive concern of various circles of society.There is low, the surperficial moisture absorption easily of barriering efficiency in traditional cotton cloth respirator, very easily cross-infection and almost nil to the protection efficiency of virus takes place, and its barrier propterty is compared with the protective mask standard GB19083-2003 of China, American-European protective mask standard all has very big gap.For this reason, exploitation can effective filtering noxious virus, the filtering material of bacterium becomes the focus that national health protection field presses for the key issue of solution and whole world research in recent years.
In order to solve above-mentioned mouth mask problem, the researcher has carried out big quantity research to anti-virus mouth mask filter material.Chinese invention patent CN2621068Y and CN1557514A utilize spraying or the method for soaking is coated to particulate matters such as photochemical catalyst nano titanium oxide on the mask material, utilize photocatalysis principle to make the virus protein sex change to reach the purpose of kill virus.The mouth mask surface that obtained by this method is owing to applied the respiratory resistance that photocatalyst layer can increase mouth mask greatly; Have a strong impact on the comfortable wearing sense; And the nano particle that applies sucks by human body and will cause serious respiratory disease, and human body is caused very big irreversible injury.In order to increase the security performance of anti-virus mouth mask; Chinese invention patent CN1970115A, CN1462642A and CN1552394A have proposed a kind of anti-virus mouth mask with health care that prevents virus intrusion human body through the method that in mouth mask, increases Chinese medicine medicine core; This mouth mask medicine core is made and is divided into a plurality of steps such as drying, pulverizing, screening, classification and sterilization; The preparation process is very complicated; And under the moist condition in oral cavity, Chinese medicine medicine core very easily lost efficacy, and caused it to kill the continuous decay that removes the germ performance.At present, to be preferably the meltblown fibers nonwoven of handling with electret be the mouth mask of core filter material to serviceability.It is 0.3 micron meltblown fibers non-woven fabrics gauze mask material that China publication CN1565701A provides a kind of fiber diameter of handling through electret; Fiber is after electret is handled; Can improve filter efficiency through electrostatic adsorption; But because the restriction of work principle of filter, the adsorbance of this filter material is easy to reach capacity, and the electret quantity of electric charge also can be decayed along with the rising of environment for use temperature and humidity gradually; And then reduce the barrier propterty of mouth mask greatly, can't realize high efficiency filter to germ.
But static spray network technology prepares the new method of the compound multi-layer film material of one dimension electrospinning fibre and two-dimension netted tunica fibrosa as a kind of one-step method, has caused the concern of academia and industrial quarters.Common one dimension electrospinning fibre and two-dimension netted film (average fibre diameter is less than 20 nm in the net) mutual superposition in the static spray net composite membrane finally form a kind of porous film material.This film has that fibre diameter is little, specific area is big, the aperture is little and the porosity advantages of higher, can effectively stop the invasion of deleterious particles such as bacterium, virus, has kept higher gas permeability simultaneously.
