Abstract
The utility model discloses a respirator capable of filtering PMs (Particulate Matters) 2.5. The respirator comprises a hanging belt and a respirator layer connected with the hanging belt. The respirator is characterized in that the respirator layer adopts a six-layered structure, a first layer of the respirator layer is an outer cover cloth layer, a second layer of the respirator layer adopts new material high-efficiency filter layer, a third layer of the respirator layer adopts melt-blown non-woven fabric layer, a fourth layer of the respirator layer adopts new material high-efficiency filter layer, a fifth layer of the respirator layer adopts melt-blown non-woven fabric layer, and a sixth layer of the respirator layer adopts face laminating layer. The respirator has the benefits that the filtration efficiency value of the respirator is more than 99 percent, and the respiratory resistance value is far lower than a specified limit value of the national standard KN95; the respirator is suitable for being worn under the air environment in which the PMs 2.5 exceed the standard.
Description
Technical field
The utility model relates to the mouth mask of a kind of PM2.5 of filtration, and being applicable to daily life, laboratory, school, hospital, factory etc. and having has the crowd of requirement to use to air pollution protection under the various occasions of dust and particulate.
Background technology
Domestic and international many cities have all occurred that serious haze pollutes weather, and this increases with urbanization, vehicle in recent years, industrial fast development is closely related.The mechanism that haze weather produces is a lot, and its chemical composition is also very complicated, and it is not a kind of material, but tens kinds of materials, these materials may cause cancer and other serious disease.PM2.5 endangers maximum fine particle to people in air pollutants, and the diameter of this fine particle is equal to or less than 2.5 microns.PM2.5 can enter lung particle medically crying, and in general medical mask probably can effectively filter the particulate of PM4, but not good to the filter effect of PM2.5 particulate, and current anti-PM2.5 General Requirements reaches other mouth mask of N95 level.
In the face of the present situation of polluting, the mouth mask of the materials such as all kinds of gauzes on market, cotton, nonwoven, is all described to the mouth mask of anti-PM2.5, even also has the Simple mask of taking to pretend to be the anti-particle mouth masks such as N95.And in fact judging that can mouth mask anti-PM2.5, outward appearance or the gauze number of plies of product of not take is standard, be with composite targets such as filter efficiency, slip and respiratory resistances, and the testing result of relevant PM2.5 instrument verified.
According to different purposes and demand, mouth mask has different kinds and classification, is simply described as follows:
General mouth mask: this mouth mask does not pass through extra processing, the hole of its fibre structure is large (approximately 10 microns) quite, such mouth mask, for the effect of protection not of the micronic dust than being easier to enter human respiratory system, only plays certain iris action to the larger dust of particle.
Active carbon mask: active carbon has mushy structure.The main function of its filter course is to adsorb organic gas and dust.This active carbon mask activated carbon powder used is very easily saturated, and adsorption efficiency is reduced in the short time greatly.Activated carbon powder easily comes off simultaneously, filtering function was lost efficacy, and the porous nickel in activated carbon powder is bad, and absorption property is unstable, cannot meet the requirement of quick adsorption and isolated stink.
Medical mask: medical mask is mainly to affect disease for fear of the spittle, Functional Design is not to avoid sucking granular nuisance, the surgery Medical mask of standard can block more than 90% particle of 5 microns, but almost there is no protection effect for PM2.5.
Summary of the invention
For solving existing the problems referred to above that exist with protective mask, the utility model provides a kind of PM2.5 suspended particulate in filtered air that has of silica aerogel new material making, and respiratory resistance is little, the protective mask of comfortable wearing.
In general, silica aerogel is colourless nontoxic, and specific area is large, and porosity is high, has very strong adsorption capacity, can fully contact with fine particle thing, thereby play catharsis.Yet, in experiment, find that most silica aerogel nano material can not filter PM2.5 suspended particulate well.
The scheme that the utility model technical solution problem is taked is, employing is in the Silica Aerogels prepared of raw material, to select to have PM2.5 is had to the Silica Aerogels of good filter effect or its mixture and/or active carbon to mix by a certain percentage from (CN201310343936.X, the CN201310344363.2) of independent research by alkoxy silane, through apply or single layer structure that spray fusing forms on acrylic resin (PP), polyester resin (PET) or spun laced fabric as new material high efficiency filter layer.
The technical solution of the utility model is the mouth mask layer that comprises suspender belt and be connected with suspender belt, and described mouth mask layer is six layers of structure, and wherein ground floor is outer cover layer of cloth; The second layer is new material high efficiency filter layer; The 3rd layer is melt-blown nonwoven layer of cloth; The 4th layer is new material high efficiency filter layer; Layer 5 is melt-blown nonwoven layer of cloth; Layer 6 is facial laminating layer.
Described outer cover layer of cloth and facial laminating layer are nonwoven, cotton or bamboo fibre cloth.
The Silica Aerogels that described new material high efficiency filter layer is prepared for one or more alkoxy silanes or its mixture and/or active carbon mix rear coating or the single layer structure of spray fusing on carrier by a certain percentage.
The specification of described new material high efficiency filter layer is 30～75g/m
2, the Silica Aerogels that wherein prepared by one or more alkoxy silanes or the content of its mixture and/or active carbon are 10～50g/m
2.
The specification of described melt-blown nonwoven layer of cloth is 15～40g/m
2.
Described coated carrier is acrylic resin (PP), polyester resin (PET) or spun laced fabric.
The beneficial effects of the utility model are, have dustproof effect, high to the filter efficiency of airborne micron, Ya Na meter or nanoscale suspended particulate and neutral corpuscle, can effectively filter PM2.5 suspended particulate.Bing Jing authoritative institution is detected, and filter efficiency value is greater than 99%, and respiratory resistance value is far below the prescribed limits of GB KN95, is adapted at wearing under air ambient that PM2.5 exceeds standard.
