Description
Technical field
The present invention relates to a kind of polytetrafluoroethylene (PTFE) (e-PTFE) microporous barrier composite screen, be applicable to Household Air Purifier.
Background technology
Along with the rapid growth of China's economy, in how regional air, PM2.5 granule density value is higher becomes objective reality, and multiple provinces and cities of China have occurred continuing dense haze weather; The pay attention to day by day of country to environmental protection, " ambient air quality " of new revision too increases PM2.5 monitoring index, these all make people more and more pay close attention to " PM2.5 ", and along with the reinforcement of people's environmental consciousness, air quality has become the focus that the whole nation is paid close attention to.
In China, the indoor overwhelming majority such as house, office building does not have air filtering system, and people spend the time of 90% in indoor, room air pollution level is but outdoor 2 ~ 5 times, the pernicious gases such as pollen, mould, spore, hair, smog, bacterium, virus, dust and formaldehyde, benzene,toluene,xylene, TVOC are all contained in indoor nearly all space, along with the continuous reinforcement of the day by day severe of IAQ and people's environmental consciousness, removing indoor air pollutants with air purifier is a kind of effective method.In current air purifier market, the HEPA filter using fine glass fibre as filter medium is in occupation of leading position.But the filtration resistance of HEPA filter screen is higher, strainability and service life are all not ideal, thus have impact on the clean-up effect of air purifier.
Polytetrafluoroethylene (PTFE), owing to having chemistry and the physical property of a series of excellence, is very important a kind of engineering plastics, has application in a lot of field, is also a kind of important membrane material.Microporous teflon membran except having excellent chemistry and physical property, and due to advantages such as its aperture is little, porosity is high, waterproof and breathable, wind-proof warmings, has important application prospect in fields such as chemical industry, medical treatment, clothes, electronics.At present; polyfluortetraethylefilm film coated filter material has been widely used in the supporting sack cleaners of dust-filtering such as metallurgy, coal-burning power plant, garbage burning factory, cement plant, coal-burning boiler, makes overlay film filter material in environmental protection, give play to unprecedented core force just because of the strainability that microporous teflon membran is good.But due to technical merit, microporous teflon membran is not applied in domestic purifier field.
Summary of the invention
The object of the invention is the deficiency solving HEPA filter screen in prior art, a kind of air purifier microporous teflon membran composite screen is provided, makes it have excellent strainability and clean-up effect, there is lower filtration resistance and longer service life.
Technical scheme
A kind of air purifier microporous teflon membran composite screen, comprises one deck microporous teflon membran and layer of non-woven fabric, described microporous teflon membran and non-woven fabric compounded integral.
The grammes per square metre of described non-woven fabrics is 50 ~ 200g/m
2.
The grammes per square metre of described microporous teflon membran is 1.0 ~ 6.0 g/m
2, air penetrability is 10 ~ 15 cm/s, and the described microporous teflon membran trade mark is ePTFE-N, is produced by Zhongcai Sci. & Tech. Co., Ltd.
Described microporous teflon membran is the microporous teflon membran through photocatalyst solution impregnation process, and described non-woven fabrics is the non-woven fabrics through photocatalyst solution impregnation process.By photocatalyst solution impregnation process to realize being combined with multifunctional filtering medium.
The preparation method of air purifier microporous teflon membran composite screen of the present invention: microporous teflon membran is overlying on non-woven fabrics by heat pressing process, obtain overlay film non-woven fabrics, by overlay film non-woven fabrics through ethanol pre-invasion to after completely transparent, impregnated in Photocatalyst water solution again, finally take out dry.
The temperature of described heat pressing process is 80 ~ 150 DEG C, hot pressing pressure is 0.1 ~ 2Mpa.
Described heat pressing process is that hot melt presses, hot pressing overlay film or PUR bonding.
The mass concentration of described Photocatalyst water solution is 0.01 ~ 1%.
The dip time of described overlay film non-woven fabrics in Photocatalyst water solution is 0.1 ~ 48h.
Household Air Purifier microporous teflon membran composite screen of the present invention can filter PM2.5, sterilization, deodorizing, except pernicious gases such as formaldehyde, benzene,toluene,xylene and TVOC, filter screen is to filter efficiency >=99.97% of PM2.5 particle, windage≤120Pa, to pernicious gas (formaldehyde) purifying rate >=95%.
Household Air Purifier microporous teflon membran composite screen of the present invention has the strainability higher compared with HEPA filter screen, lower filtration resistance and more long life (HEPA filter screen PM2.5 filter efficiency≤99.97%, filtration resistance is 220 ~ 400Pa), filter screen of the present invention is used in air purifier, the high-barrier of filter screen, the clean-up effect of No leakage performance guarantee air purifier, highly-breathable will mean lower energy consumption, less noise, viscosity does not make filter screen can by repeatedly deashing Reusability without the need to direct replacing, thus possessed longer service life.Composite screen of the present invention significantly can also reduce energy consumption and the noise of air purifier simultaneously, is the good substitute products of HEPA filter screen, is worth producing and promoting.
Accompanying drawing explanation
Fig. 1 is the structural representation of air purifier microporous teflon membran composite screen of the present utility model.
Detailed description of the invention
In order to understand the present invention better, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
