Therefore, the air conditioner purification filter screen disclosed by the embodiment of the invention has antibacterial and antiviral properties and fine particle filtering properties, not only can the air filtering quality be obviously improved, but also the breeding and propagation of microorganisms on the filter screen can be effectively avoided, the service life of the filter screen is further prolonged, and the secondary pollution to indoor air, the indoor air quality damage and the influence on human health are avoided.
The air conditioner purifying filter net of the embodiment of the invention is described in detail as follows:
according to a specific embodiment of the present invention, the antibacterial and antiviral nonwoven fabric is specifically formed of polymer fibers having silver-loaded copper zeolite loaded on the surface thereof. Therefore, the formed non-woven fabric has antibacterial and antiviral properties by loading the silver-loaded copper zeolite on the polymer fibers. And the silver-loaded copper zeolite is exposed on the surface of the fiber and can be fully contacted with air, inhalable particles such as bacteria and virus droplet nuclei and potential allergens filtered from the filter screen, so that the efficiency and the effect of sterilizing and removing viruses are effectively improved.
According to the specific embodiment of the invention, the silver-loaded copper zeolite is prepared by taking nano-aluminosilicate as a carrier and taking silver ions and copper ions as effective antibacterial and antiviral components. The inventors found that by introducing Cu2+Can solve the problem of easy color change existing in the process of carrying silver independently, and simultaneously Ag+And Cu+The synergistic effect of the components can also obviously improve the antibacterial and antiviral performances of the product.
According to a particular embodiment of the invention, the silver-loaded copper zeolite employed may have a crystal size of 20nm to 1 μm. More preferably, the silver-loaded copper zeolite has a crystal size of from 100nm to 200 nm. The inventor finds that by adopting the silver-loaded copper zeolite in the nanometer level, a large number of nanometer-scale holes exist among zeolite crystals, so that the capacity of capturing viruses is greatly increased, and the copper ions and the silver ions released by the zeolite carrier are convenient to attack and destroy proteins and nucleic acid molecules of the viruses. Thereby remarkably improving the sterilizing and virus removing effects of the antibacterial and antiviral non-woven fabric.
According to the specific embodiment of the invention, the antibacterial and antiviral non-woven fabric is prepared by blowing the silver-loaded copper zeolite onto the surface of the polymer fiber through a melt-blowing air flow in the melt-blowing spinning process for preparing the polymer fiber. Thus, silver-loaded copper zeolite is added to the air flow of the melt-blown spinning, and the silver-loaded copper zeolite is firmly supported on the fiber surface by the high-speed air flow blowing action and the polymer fiber melt bonding action. Specifically, the polymer fiber raw material is melt extruded, and the state of the fiber is gradually changed from melt to solid in the process from a spinneret to a fiber collecting position. The fiber melt has liquid characteristics, the surface of the fiber melt is easy to deform, and when the silver-loaded copper zeolite is sprayed to the surface of the fiber melt with certain kinetic energy, the fiber melt is stretched, lapped and cooled to be formed, so that the non-woven fabric firmly loaded with the silver-loaded copper zeolite is formed. Therefore, the method for preparing the non-woven fabric with antibacterial and antiviral properties is simple, efficient, low in cost and easy for large-scale production. More importantly, the silver-loaded copper zeolite can be firmly loaded on the surface of the polymer fiber by the method, and is not easy to fall off in the transportation and working processes, so that dust pollution can be effectively avoided; in addition, the silver-loaded copper zeolite is exposed on the surface of the polymer fiber and can be fully contacted with air, inhalable particles such as bacteria and virus droplet nuclei and potential allergens filtered from the filter screen, and further the efficiency and the effect of sterilizing and removing viruses are effectively improved.
According to an embodiment of the present invention, in the antibacterial and antiviral nonwoven fabric, the loading rate of the silver-loaded copper zeolite is 0.5 to 5% based on the total mass of the polymer fibers. The cost of the silver-loaded copper zeolite is higher, so that the dosage of the silver-loaded copper zeolite is controlled as much as possible while the antibacterial and antiviral effects are ensured, and further resource waste and cost increase are avoided. Therefore, according to a specific example of the present invention, the loading ratio of the silver-loaded copper zeolite may be preferably 0.5 to 2%.
According to an embodiment of the present invention, the polymer fiber forming the antibacterial and antiviral nonwoven fabric main body may be one or more of polyester fiber, polypropylene fiber, polyethylene fiber and polyamide fiber. According to a specific example of the present invention, the polymer fiber used for the antibacterial and antiviral nonwoven fabric main body may preferably be polyethylene terephthalate fiber. The non-woven fabric formed by the polyethylene glycol terephthalate fiber has excellent stiffness, tensile strength and wind pressure resistance, is compounded with the electret melt-blown non-woven fabric, and can greatly prolong the service life of the compound filter cloth.
According to the embodiment of the invention, the filtering main body of the air-conditioning purifying filter screen is of a double-layer composite structure, one layer is an antibacterial and antiviral non-woven fabric, and the second layer is an electret melt-blown non-woven fabric. The electret melt-blown nonwoven fabric can be F7, F8, F9, H10, H11, H12, H13 or H14 melt-blown nonwoven fabric. According to a specific example of the present invention, meltblown nonwoven fabric of H11 grade may be preferably used. Therefore, the air filter can effectively filter particles including PM10, PM2.5 and PM0.3 in the air, such as highway dust, industrial dust, pollen, mould spores, and inhalation particles and potential allergens such as droplet nuclei attached with bacteria and viruses while ensuring low wind resistance.
According to the specific embodiment of the invention, the antibacterial and antiviral non-woven fabric and the electret melt-blown non-woven fabric are superposed, compounded and pleated to form the filtering main body of the air-conditioning purifying filter screen. According to the specific embodiment of the invention, the compounding process of the two layers of non-woven fabrics can be selected from hot melt adhesive compounding, pressure sensitive adhesive compounding or ultrasonic compounding. And further the influence on the non-woven fabric filtering effect can be reduced. According to a specific example of the present invention, the material of the frame of the air conditioner purification filter screen may be one or a combination of paper, plastic, metal and spunlace cotton. Specifically, the filter main body and the frame may be fixed by hot melt adhesive. Fig. 1 shows an air conditioning purification filter screen according to an embodiment of the present invention, which includes a filter body 2 and a frame 3, and fig. 2 shows a cross-sectional view of the air conditioning purification filter screen at a position a-a in fig. 1, and it can be seen that an antibacterial and antiviral nonwoven fabric 4 and an electret meltblown nonwoven fabric 5 are laminated and pleated.
The air conditioner purification filter screen according to the embodiment of the invention has excellent antibacterial, antibacterial and antiviral properties and particulate matter filtering properties. Specifically, the antibacterial rate of staphylococcus aureus can reach 99.9%, the sterilization rate of staphylococcus albus can reach 99.8%, the antiviral rate of H1N1 can reach 99.9%, and the clean air content of particulate matters can reach 515m3/h。
