Abstract
The invention discloses a disposable non-woven mask. The mask comprises multiple filter layers, fixing straps, an inner non-woven layer, a traditional Chinese medicine layer, an antibacterial layer, an activated carbon fiber layer and an outer non-woven layer; all the layers are mutually bonded through a hot melt adhesive to form the mask, one side of the inner non-woven layer directly makes contact with the skin, the traditional Chinese medicine layer is soaked through traditional Chinese medicine decoction and then taken out and dried in the air, the antibacterial layer is evenly coated with a nano-titanium dioxide neodymium-loaded antibacterial agent layer with the particle size equal to 100 nm, and the surface of the activated carbon fiber layer is loaded with catalysts. At least one side face of a bactericidal layer is evenly coated with the coating, the coating is a titanium dioxide antibacterial agent coating, and the interior of a porous material layer is evenly filled with activated carbon or zeolite or bamboo charcoal or a mixture of the activated carbon, the zeolite and the bamboo charcoal. The mask is good in antibacterial property, ultra-strong in adsorption property and refreshing in flavor and has the function of moistening the lung simultaneously.
Description
Technical field
The present invention relates to a kind of non-woven fabrics gauze mask, particularly a kind of disposable non-woven lint face mask.
Background technology
Indoor-outdoor air quality and health have substantial connection.Due to building close, ventilation condition is poor, a large amount of furniture and household electrical appliance all occupy respective corner in indoor, these corners or become the place of dust and contamination build-up, or in use send gas and the radiation of contaminated environment.
Mouth mask is widely apply in medical personnel as a kind of amenities at first.Along with the continuous deterioration of industrial development and environment, the harmful substance such as dust, industrial waste gas enters human body by respiratory tract and produces harm greatly to health of masses.In order to reduce this harm, non-woven fabrics gauze mask is widely used in much work and life occasion.Common protective mask is made with gauze and is formed, and only has general filtering function, and does not have disinfection function.
Along with the deterioration of air quality, increasing appears in thick weather phenomenon, and harm increases the weight of.The many areas of recent China are incorporated to mist together as diastrous weather early-warning and predicting using thick weather phenomenon, are referred to as " haze weather ".Directly can enter bronchus after PM2.5 micronic dust is inhaled into human body, the gas exchanges of interference lung, causes the disease comprising the aspects such as asthma, bronchitis and cardiovascular disease.According to prior art, there is a lot of disposable non-woven lint face mask, but all only filter dust, PM2.5 micronic dust cannot be filtered, the carbon monoxide in haze and aldehydes also cannot be stoped to enter respiratory tract and the lung of people.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of disposable non-woven lint face mask, this mouth mask have good anti-microbial property, superpower absorption property and taste pure and fresh while moistening lung function.
It is as follows that the present invention solves the problems of the technologies described above taked technical scheme:
Disposable non-woven lint face mask of the present invention, comprises multiple layers of filters and fixed band, it is characterized in that, is interior nonwoven layer from inside to outside, and Chinese traditional medicine layer, antibiotic layer, activated carbon fiber layers and outer nonwoven layer form by PUR is bonding between each layer.
Described interior nonwoven layer side directly contacts skin.
Described Chinese traditional medicine layer is that traditional Chinese herbal decoction was soaked, by each to cordate houttuynia, Tea Polyphenols, peppermint and aster 10 grams, put together and be brewed into traditional Chinese herbal decoction, dry in the air to non-woven fabrics being put into decoction time warm and soak 30 minutes, the non-woven fabrics soaked is pulled out to dry and is obtained Chinese traditional medicine layer.Be not single playing a role between above-mentioned four kinds of Chinese medicines, above-mentioned four kinds of Chinese medicine fit applications had the effect of " mutual reinforcement between ", can curative effect be strengthened, for effect of moistening lung and smell, be significantly better than single use, be better than the cooperation of two kinds or three kinds yet.Wear this mouth mask and can breathe the pure air filtered through mouth mask; and light four kinds of powder of Chinese traditional medicines send the Chinese medicine odor useful to health; feel that respiratory tract and lung are very comfortable, wear this Herb medicine gauze mask serves well protection and anti-inflammatory moistening lung effect to the respiratory tract of people and lung.
Described antibiotic layer even spread particle diameter is the nano TiO 2 carrying neodymium antiseptic coating of 100nm, preparation method be by the nano TiO 2 carrying neodymium antiseptic of 100nm under the effect of calgon, the obtained nano TiO 2 carrying neodymium antiseptic dispersion liquid of dispersion in milling apparatus, then, dispersion liquid is sprayed or brushes in nonwoven layer, through 60 ~ 100 DEG C through 10 ~ 30 minutes obtained antibiotic layers.Antibiotic layer has good broad spectrum antibacterial, especially to the anti-microbial property of Escherichia coli, staphylococcus aureus, Candida albicans.Nano titanium dioxide anti-bacterial agent has superpower adsorption capacity, the harmful substance such as PARA FORMALDEHYDE PRILLS(91,95), benzene, toluene, ammonia and dust can play absorption, decompose the effect of peculiar smell and smelly eliminating.
Described activated carbon fiber layers, its area load has catalyst, and the preparation method of catalyst, for taking a certain amount of Ag-Ti-MnO2, adds a certain proportion of deionized water and 30% silica adhesive, high-speed stirred 1 ~ 24h, obtain certain density slurries, slurries are coated in the mullite of anticipating, at 600 DEG C of roasting 14h, then by the catalyst soakage that obtains in the precursor water solution of platiniferous and gold, wherein the concentration of Pt and Au is 0.02mol/L, 110 DEG C of oven dry, 400 DEG C of roasting 6h.Then obtained in the oxygen of 350 DEG C and hydrogen circular treatment 12h by the mullite of carried noble metal, wherein the mass ratio of Ag, Ti, Pt, Au and MnO2 is 1:5:1:1:20.The active component of catalyst is under this ratio, and the complex role due to manganese-platinum-Jin-silver-titanium makes the catalytic activity of catalyst best.At room temperature formaldehyde and catalyzing carbon monoxide are removed simultaneously, anti humility performance is strong, good stability, treatment effeciency are high, treating capacity is large, process is complete, cost is low, there is no secondary pollution and do not adsorb the problems such as saturated.Active carbon has protection against the tide, purify air, eliminate the effect of peculiar smell, has good filtration to pungent gas, also the harmful substance such as PARA FORMALDEHYDE PRILLS(91,95), benzene, toluene, ammonia and dust can play the effect absorbed.
After this invention takes such scheme, three layer filtration layer be not single play a part respectively respective, by cooperatively interacting, Be very effective improves, activated carbon fiber layers, dust and harmful substance are adsorbed, formaldehyde in haze, benzene, toluene, the harmful substances such as ammonia at room temperature just can catalytic elimination, nano titanium oxide in antibiotic layer receives the irradiation of sunshine, there is the effect of bactericidal, afterwards through Chinese traditional medicine layer, moistening lung delicate fragrance, absorption does not have dust and the harmful substance of removing simultaneously yet, the complex role high efficiency filter of three layer filtration layer falls harmful components main in haze, filter effect reaches more than 95%.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is described further.
