Description
Technical field
The present invention relates to a kind of air sterillization material for core and preparation method thereof, particularly relate to a kind of by changing
Learn key by high poly-iodide ion air sterillization material for core being bonded to fiber surface and preparation method thereof.
Background technology
Air in public place is the main media of pathophoresis, therefore public field under the conditions of presence of people
Air sterillization just become the important leverage of public health security.
The method that air sterillization at present is commonly used has the most several:
Method 1: physics air disinfection method
(1) ultraviolet of ultraviolet air sterilization: 250nm～270nm has stronger bactericidal action, purple
The bactericidal effect of outer lamp is directly related with irradiation time and exposure rate, therefore, when utilizing ultraviolet sterilization,
Must there be enough sterilizing times and exposure rate, to guarantee effectively to kill antibacterial.Owing to ultraviolet disappears
The irradiation time of poison is longer, and ultraviolet long-term irradiation is harmful, so ultraviolet air sterilization, no
Possesses the air sterillization in the case of presence of people.
(2) plasma air disinfection: plasma is a kind of novel disinfectant, it is also possible to for air
Sterilization.The plasma screen of the design such as Gregory Fridman [US:20130330229A1] can be at several millis
The antibacterial in air and virus is killed in Miao.But some compositions in plasma such as gamma-rays, beta-particle pair
People knows from experience generation major injury, is not suitable for the air sterillization in the case of presence of people.
Method 2: chemical air sterilization method
(1) peracetic acid method: peracetic acid is a kind of wide spectrum, efficient, cheap biocide, at resist SARS
During be once widely used.Peracetic acid may be used for medical apparatus sterilizing sterilizing and surrounding air, thing
The disinfections of epidemic focus such as surface and prophylactic disinfection.The catabolite of peracetic acid be hydrogen peroxide, acetic acid,
Water and oxygen, if these are little to harm, but people's Long Term Contact, not only can cause respiratory tract disease,
And skin can become coarse, peel dry and cracked, thus does not the most possess the air sterillization in the case of presence of people.
(2) Ozone: ozone (O3) it is oxygen (O2) allotrope, ozone oxidoreduction electricity
Position is 2.07V, and oxidation-reduction potential is only second to fluorine, has extremely strong oxidisability.The stability series extreme difference of ozone,
The most just can be with automatic classifying as oxygen, so ozone can not store, it is merely able to existing existing preparation.Ozone
When being used for air sterillization, it is usually and an ozonator is installed the most within air-conditioning systems, be former with air
Material, utilizes the methods such as ultraviolet radiation method, electrolysis, corona discharge method to prepare ozone, spreads with purification fan
In the interior space, thus room air and chamber internal surface are sterilized.Ozone is a double-edged sword, is disappearing
While poison, owing to ozone stimulates body mucous membrane tissue, may result in have hot coppers, cough, uncomfortable in chest, asthma
Etc. respiratory tract disease, the most do not possesses the air sterillization in the case of presence of people.
(3) Chlorine Dioxide Method: the molecular formula of chlorine dioxide (chlorine dioxide) is ClO2, by one
Chlorine atom and two oxygen atom compositions, oxidation-reduction potential is 1.5V, is yellow green gas or red at normal temperatures
Color explosivity crystallizes, and has the strongest zest taste.Chlorine dioxide corrosion is relatively strong, is only used for unmanned
The air sterillization existed.
Method 3: other air disinfection method
In recent years, it has been recognized that, gas fumigation sterilization is to kill and remove space microorganism to pollute relatively
Effective means, conventional fumigant includes formaldehyde, vaporized hydrogen peroxide etc..Formaldehyde sterilizes due to it
Effective, price is low, the reason such as easy and simple to handle, be still conventional stifling of hospital of China, laboratory at present and disappear
Toxic agent.But having research display, formaldehyde has potential carcinogenesis, and life-time service is hazardous to the human body the biggest.
With Chinese herbal medicine removing toxic substances with sterilize long-standing, the Chinese medicine ancient books and records such as Compendium of Material Medica be all related to in
Medical herbs burns the method that sootiness is controlled to keep away pestilence gas.How pungent this type of medicine temperature be fragrant dry, has fragrance to ward off the effect that turbidity is wet,
Such as Folium Artemisiae Argyi and Rhizoma Atractylodis.Folium Artemisiae Argyi contains volatile oil, to staphylococcus aureus, tubercule bacillus, bacillus pyocyaneus, white
The multiple common bacteria such as larynx bacillus, bacillus subtilis, Pseudomonas aeruginosa and escherichia coli and various skin are true
Bacterium has sterilization and bacteriostasis effect in various degree.Rhizoma Atractylodis are containing atisine chloride atractydin, atractylone, hinesol and β-core amine
Oleyl alcohol etc., bar that tubercule bacillus, staphylococcus aureus, escherichia coli, bacillus subtilis and Aerugo vacation list are satisfied
Bacterium has significantly sterilization and fungistatic effect.Chinese herbal medicine sootiness does not only have a large amount of smog, and long-time sootiness is also
Respiratory tract can be stimulated to cause serious discomfort, thus be also not suitable for carrying out disinfection in the case of having people.
Physical sterilization is mainly by optical, electrical in physics and mode and the room air such as filtration, absorption
Antibacterial is killed in middle bacterial action, and chemical disinfection changes air mainly by the oxidisability of chemosterilant
The cellularity of middle antibacterial so that it is the breeding of metabolism normally can not cause death.Gas fumigation method is by sterilization
Material affects the metabolism of antibacterial to kill antibacterial.Above-mentioned three class methods can kill sky in various degree
Harmful microorganism in gas, but once sterilize stopping, or have the impact that personnel come in and go out so that after sterilization,
Space bacteria colony count rises very rapidly up to the clump count before not sterilizing, even quantity than the clump count before not sterilizing
Taller.
In a word, current air disinfection method have that disinfectant Disinfection Effect is poor, residual contamination, corrosivity strong,
The shortcomings such as disinfection cost is high or sterilizing equipment decontaminating apparatus involves great expense, use process is complicated, the most all can not have people
Under the conditions of carry out disinfection.
High poly-iodine is the safe and efficient disinfectant of one generally acknowledged the most in the world, its effective sterilization component
For high poly-iodide ion；High poly-iodide ion is the polymer of iodide ion and iodine molecule, and its structural formula isM is
