Abstract
The utility model relates to a non-woven fabric and nano film compound material capable of blocking PM2.5 particles. The compound material comprises an outer-layer non-woven fabric (1), a core-layer nano material film (2) and an inner-layer non-woven fabric (3). The material provided by the utility model can effectively block damage to human bodies caused by PM2.5 in air, so that people are no longer afraid of hazy weather. The compound material provided by the utility model can be prepared into a window curtain capable of being freely folded, so that people just unfold the window curtain in hazy weather to open the window to breathe freely. The material can be further used in parts such as an automobile window and an intake valve of an engine to reach the effect of blocking PM2.5. Meanwhile, the material provided by the utility model can be further prepared into a protective facial mask, so that people can go out freely in hazy weather.
Description
Technical field
The utility model relates to the composite that can stop PM2.5 particle, particularly relates to a kind of nonwoven and nanometer film composite that can stop PM2.5 particle.
Background technology
Along with economic develop rapidly, mankind's pollution on the environment is also more and more serious, and the haze phenomenon of China is also more and more, and people more and more pay close attention to PM2.5 particle to healthy impact.PM2.5 refers to that aerodynamics equivalent diameter in surrounding air is less than or equal to the particle of 2.5 μ m, fine particle enters human body after alveolar, directly affect the ventilatory function of lung, make body easily be in anaerobic condition, particle can damage respiratory system and cardiovascular system simultaneously, cause asthma, lung cancer, angiocardiopathy, inborn defect and dead too early, very large to the harm of health.Therefore the protection of PM2.5 is become to the focus that people pay close attention to.During haze weather, people's ventilation of can not windowing, also will be with thick mouth mask when outdoor activity, and haze weather brings a lot of inconvenience to people's work and life.The utility model is devoted to address this problem, and a kind of nonwoven nano composite membrane that can stop PM2.5 is provided, and can be applied to multiple occasion, stops the infringement of PM2.5 to human body, makes people can normally work and live at haze weather.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of nonwoven and nanometer film composite that can stop PM2.5 particle.
The utility model solves the technical scheme that its technical problem adopts: a kind of nonwoven and nanometer film composite that can stop PM2.5 particle is provided, and described composite comprises outer nonwoven, sandwich layer nano material film, internal layer nonwoven; Its ectomesoderm nonwoven, sandwich layer nano material film, internal layer nonwoven adopt method laminated into type to be bonded together.
Described outer nonwoven can adsorb and stop most of dust and pellet.
Described outer nonwoven is SM compound nonwoven cloth, the SM compound nonwoven cloth of SM compound nonwoven cloth for making with superfine polypropylene material.
Described sandwich layer nano material film effectively filters the particle that diameter is less than or equal to 2.5 μ m.
Described sandwich layer nano material film is superpower occluding material.
The electrospun fibers film of the difficult soluble macromolecular polymer of described sandwich layer nano material film.
The electrospun fibers film of described slightly solubility high molecular polymer is polyacrylonitrile fibre, polypropylene fibre or nylon fiber.
Described sandwich layer nano material film is the electrospun fibers film of the slightly solubility high molecular polymers such as polyacrylonitrile, polypropylene or nylon.
The features such as it is little that described nanometer film has fibre diameter, and specific area is large, and porosity is high, and between fiber, hole dimension is little, high adsorption capacity, can effectively filter the granule that diameter is less than or equal to 2.5 μ m.
Described internal layer nonwoven is cotton fiber or terylene spunlace non-woven cloth.
Described internal layer nonwoven is soft comfortable, and has good breathable moisture permeability.
Describedly laminated into typely refer in heating, add depress multi-layer phase together or different materials in conjunction with whole method for processing forming, by tonnage, can be divided into two kinds of high-pressure process (high pressure zone moulding) and low-pressure processes (low-pressure laminating).
beneficial effect
Owing to having adopted above-mentioned technical scheme, the utility model compared with prior art, has following advantage and good effect: (1) the utility model can effectively stop PM2.5 particle; (2) the utility model is applied widely, can be used for multiple occasion; (3) it is flexible that the utility model is used the product of making, and use value is high; (4) the utility model consumption demand is large, and market prospects are considerable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model, outer nonwoven 1, sandwich layer nanometer film 2, internal layer nonwoven 3;
Fig. 2 is the ESEM pattern of polyacrylonitrile superfine fibre.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment are only not used in restriction scope of the present utility model for the utility model is described.In addition should be understood that those skilled in the art can make various changes or modifications the utility model after having read the content of the utility model instruction, these equivalent form of values fall within the application's appended claims limited range equally.
Embodiment of the present utility model relates to a kind of nonwoven and nanometer film composite that can stop PM2.5 particle.Comprise outer nonwoven 1, sandwich layer nano material film 2, internal layer nonwoven 3, its ectomesoderm nonwoven is SM compound nonwoven cloth, sandwich layer nano material film is polyacrylonitrile fibre, and internal layer nonwoven is cotton fiber or terylene spunlace non-woven cloth, adopts method laminated into type to be bonded together.
The preparation process of nanometer film (with the example that is prepared as of polyacrylonitrile nanofiber): 5g polyacrylonitrile fine powder is added and fills 50mL N, in the Erlenmeyer flask of N-dimethylacetylamide, swelling 24h under the stirring of 250rpm rotating speed and 60 ℃ of water bath condition, is cooled to room temperature and prepares spinning.
Spinning solution is packed in reservoir after ultrasonic 15 minutes, No. 5 syringe needles (internal diameter 0.5mm) that employing is scabbled are as the capillary that sprays thread, connect high pressure generator (ZGF2000 type, Shanghai Su Te Electrical Appliances Co., Ltd), use micro-injection pump (U.S. Cole-Parmer company) to control and advance speed, adopt aluminium foil flat board to accept fiber.
Electrospinning process parameter is: flow velocity is 0.8mL/h, and dash receiver is about 12cm apart from spinning nozzle distance, voltage 15kV, and environment temperature is (16 ± 1) ℃, ambient humidity is 60 ± 5%.
The utility model can be made curtain that can freedom retractable, and when haze weather, people only need this curtain to put down, the free ventilation of just can windowing, and the indoor injury that can not be subject to PM2.5 particle; The utility model can also be for automobile engine air inlet and automotive window curtain, and people can be in the trip of still driving of haze weather, can also follow one's bent to beat to open the window and do not worry oneself health; The utility model also can be made Novel protective mothpiece simultaneously, can effectively hinder PM2.5 particle, and in addition, the utility model also has many other application examples, can effectively intercept the infringement of PM2.5 particle.
