Description

Antibacterial mask filter disc and preparation method thereof and antibacterial mask
[technical field]
The present invention relates to medical material tech field, particularly relate to a kind of antibacterial mask filter disc and preparation method thereof and antibacterial mask.
[background technology]
Currently, the situation is tense in In The Atmosphere Over China pollution.According to the urban air-quality daily paper that Chinese Ministry of Environmental Protection announces January in this year, front 10 cities that API (AirPollutionIndex) pollution index is the highest are: Shijiazhuang, Handan, Baoding, Tangshan, Tianjin, Zhengzhou, Jinan, Qinhuangdao, Jining, Urumchi and Wuhan (side by side).This ranking does not also include PM2.5 and ozone pollution index.Wherein the ground air quality such as Beijing, Hebei, Shandong reaches severe contamination, PM2.5 index presses on towards maximum, as Shijiazhuang, Handan, Xingtai, Hengshui air quality index even " quick-fried table ", numerical value has met or exceeded the measurement upper limit of 500, primary pollutant mostly is PM2.5, PM10, Pekinese PM2.5 value breakthrough 900.
Surrounding objects can not only be produced damaging influence by physics, chemistry, biological corrosion function by air pollution, and our respiratory system, nervous system, immunocompetence, skin, liver, hormonal system etc. are produced toxic action through positions such as respiratory system (pulmonary), epiderm skins by dusty gas.The mental status of people can be affected, it is easy to the untoward reaction such as tired, nervous occur simultaneously, reduce work, the learning efficiency.Live and work in the long-term environment poor in air quality, respiratory function not only can be caused to decline, respiratory symptom increases the weight of, also result in the diseases such as chronic bronchitis, bronchial asthma, emphysema, the serious increase also resulting in pulmonary carcinoma, nasopharyngeal carcinoma prevalence.Therefore, become increasingly conspicuous with the regional atmospheric environment problem that pellet (PM10), fine particle (PM2.5) are characteristic contamination, infringement body health of people, affects social harmony stable, and In The Atmosphere Over China pollution control is very urgent.
In personal protection, composite filter material for personal protection, such as mask, China's mask sales volume in 2011 reaches 1,000,000,000 according to statistics, along with economy continues to increase, the raising of Living consumption, the demand of mask also will be kept quickly increasing by consumer, expecting 2016, annual requirement is up to 3,500,000,000.The filtrate of protective mask mainly divides two classes, i.e. dust-proof class and gas defence class.Their effect is all by harmful aerosol, adsorbs through filtrate, stops and do not sucked by people including dust, fumigation, droplet, poison and poison vapor etc..For the filtrate of good protective mask, should possess three below condition: one be when mask and user face closely sealed good filter efficiency high;Two is that respiratory resistance is little;Three is that user is comfortable on.The material of dust-proof class mask filtrate has multiple, including common fabric, animal wool, non-woven fabrics etc..
At present, popular in the world is a kind of synthesis, cotton through the nonwoven cloth material electrostatic of Electrostatic Treatment.Non-woven fabrics through Electrostatic Treatment is possible not only to stop big dust granules, and fine dusts can be adsorbed by the electrostatic charge being attached to its surface by electrostatic attraction, reaches significantly high dust collection efficiency;And the thickness of filtrate is but very thin, greatly reduce the respiratory resistance of user;In China, some mechanisms have studied and have adopted electrostatic spinning to make nanofiber for the filtrate of mask, form mask filtering material as patent publication No. CN103520999A, patent publication No. CN103445329A, patent CN203467712U, patent publication No. CN102920067A, patent publication No. CN102872654A and patent publication No. CN102872653A etc. have studied to be combined nanofiber with supporter as sandwich layer.But these patents are mainly the achievement in research of laboratory, and distance industrial production scale is also far, and main technical bottleneck is the large-scale production of electrostatic spinning.Electrostatic spinning is a kind of and the diverse weaving technology of traditional textile technology, the feature that the fiber filter film that it is prepared has fiber finer, aperture is little, porosity is high, but electrostatic spinning technique can be adopted to carry out producing nanofiber filtration material in enormous quantities and carry out the technology of commercial Application also rarely found in the world at present.
