Description
Technical field
The present invention relates to a kind of mask, especially a kind of Multifunctional gauze mask with antibacterial, automatically cleaning and safeguard function and
Preparation method.
Background technique
" the climate change Green Book: reply climate change report that the Chinese Academy of Social Sciences, China Meteorological Administration's joint are issued
(2013) " (hereinafter referred to as " Green Book ") is pointed out, Chinese haze weather is totally in increase trend in the past 50 years.Wherein, mist number of days
In significantly reducing, haze number of days is obviously increased, and duration haze process increases significantly.Green Book claims, and Chinese haze weather increases most
Main reasons is that Air Pollutant Emission caused by social fossil energy consumption increases gradually increases, major influence factors are
The release of organic pollutant caused by the imperfect combustion of fossil energy, oxycarbide, and the main source of these pollutions is heat
The especially heavy Chemical Manufacture of electricity discharge, industry, vehicle exhaust, heat supply in winter, resident living (culinary art, hot water) and ground ash
Dirt.Generating haze weather main cause is P2.5 too high levels in air.The partial size of Atmospheric particulates 0.01~100 μm it
Between, it is referred to as overall suspended pellet, PM2.5 refers to that aerodynamic diameter is less than or equal to 2.5 μm of particulate matter.Epidemiology is ground
Study carefully and show that aerosol particle object of the partial size less than 2.5 μm can enter lung, and is deposited on alveolar, and particle is smaller, it is easier
The heavy metal and organic matter, bacterium and virus of some couples of human hazards are adsorbed, mainly: increasing morbidity and mortality；Harm
Respiratory system and cardiovascular system；Change lung function and its structure；Change immune function；Increase cancer to suffer from, such as lung cancer, to the mankind
Health causes to seriously endanger.The process administered for haze source of generation is considerably complicated and difficult, in physical protection and haze root
For source is compared in terms of administering two, the exploitation and progress of human body protection technique seem more convenient and effective.It is worn when outgoing special
Industry protective mask is to protect one of the important method of compatriots' health under current weather condition.Haze-proof mask is increasingly becoming fast sale
Product.
The main reason of haze is that kinetic diameter is excessively high less than or equal to 2.5 μm of particle content in air, and contains
The mask for having a large amount of organic pollutants, oxycarbide, a nitrogen oxides, and largely using on the market at present be largely pure cotton or
The anti-dust mask of person's non-woven fabrics production can play the role of filtering barrier for general slightly larger particle, but for haze
In it is poor to the maximum micro-/ nano particle filtering barriering effect of human injury, almost to the catalytic degradation effect of organic pollutant
It is zero.Apparent haze effect is not had.And so-called haze mask, protection and wherein organic contamination for haze
The catalytic efficiency of object be generally lower than 10% in addition some down to 1.1%, more some masks itself are made human body containing toxic
At directly injury.The quality problems of haze-proof mask are very prominent, quite industry allowed to worry.Shanghai City Administration of Quality and Technology Supervision announces a few days ago
To the quality safety Risk Monitoring result for declaring tool " PM2.5 protection " function mask, surpasses eighty per cant product in 69 batch samples and do not conform to
Lattice.Also, most of mask is all disposable breathing mask, causes the waste and environmental pollution of resource.
The method for preparing mask at present mainly has: melt spraying non-woven fabrics technology, spun-bonded non-woven fabrics technology and woven fabric weaving skill
Art.Material used is often polypropylene and cotton fiber.Fibre diameter in spun-bonded non-woven fabrics is thicker, generally at 15~40 μm.
Fibre diameter in melt spraying non-woven fabrics is averagely less than 5 μm, but thickness is uneven.And cotton fabric is easy to produce mould, polypropylene without
The human body compatibility and comfort of woven fabric are poor.
I once obtained related patents, the patent No. 201610444058.4, a kind of entitled efficient haze in 2016
With organic pollutant mask and preparation method thereof, but in use, it is found that the nanometer titanium dioxide fiber in this mask is more
Hole film layer is easier brokenly, though reaching good effect, service life is not grown.
Summary of the invention
Based on the above issues, the purpose of the present invention is to provide a kind of more function with antibacterial, automatically cleaning and safeguard function
Energy mask and preparation method thereof；Multifunctional gauze mask of the present invention is with antibacterial, automatically cleaning, efficient anti-haze and organic pollutant
Comfort Multifunctional gauze mask；Not only there is important economic value, also there is important social effect；Reduce the waste of resource
And environmental pollution, there is good Social benefit and economic benefit.
