Embodiment 1

[0077] In this embodiment, the primary effect filter screen 1 adopts PP filament non-woven fabric with 40 meshes loaded with nano-silver antibacterial agent accounting for 0.1% of the mass of the primary effect filter screen 1; The melt-blown non-woven material with negative ion powder is prepared by discount glue coating process; the odor filter 3 is made by mixing coconut shell activated carbon material and zeolite molecular sieve loaded with potassium permanganate and filling it. After the above preparations, hot melt adhesive is used to bond and fix the primary effect filter 1, the particle filter 2 and the odor filter 3 in turn respectively; Net products; finally packaged by inflating or vacuum sealing.

Embodiment 2

[0079] In the present embodiment, primary effect filter screen 1 adopts the plastic net that 5 purpose loads have accounted for the nano-silver antibacterial agent of primary effect filter screen 1 quality 2.0%; The PTFE membrane is prepared by a discounted glue coating process; the odor filter 3 is made of coconut shell activated carbon material and alumina loaded with potassium iodide and sodium thiosulfate after mixing and filling. The preparation process is the same as in Example 1.

Embodiment 3

[0081] In the present embodiment, the primary effect filter screen 1 adopts 100 mesh loads of spunlace nonwovens that account for 5.0% of the primary effect filter screen 1 mass nano-silver antibacterial agent; 2 is the same; the odor filter 3 is made of zeolite molecular sieve loaded with ferric ammonium sulfate and alumina loaded with potassium iodide and sodium thiosulfate, mixed and filled. After the above preparations, the primary effect filter 1, the particle filter 2 and the odor filter 3 are respectively bonded and fixed around the four sides with polyurethane glue; then, the paper shell is used for edge wrapping to obtain a composite air filter Products; finally packaged by inflating or vacuum sealing.

Abstract

The invention provides a composite type air filter screen and a preparation method thereof. The composite type air filter screen includes a primary-efficiency filter screen, a particulate filter screen and a smell filter screen; the primary-efficiency filter screen, the particulate filter screen and the smell filter screen are sequentially connected to form the composite type air filter screen; the composite type air filter screen is provided with a lifetime indicating device. The composite type air filter screen allows the primary-efficiency filter screen, the particulate filter screen and the smell filter screen to be composited and superimposed to form a composite structure with three-layer filtration, and thus the filter effect is significant; moreover, the composite type air filter screen also is provided with the lifetime indicating device, so that the purification effect and the lifetime state of the composite type filter screen can be reflected in real time, a user can determine whether the filter screen needs to be replaced according to needs, and the use effect and user experience are ensured. The preparation method of the composite type air filter screen has the advantages of simple and fast process, and convenience for mass production.

Description

technical field [0001] The invention relates to the field of air purification equipment, in particular to a composite air filter and a preparation method thereof. Background technique [0002] With the development of modern industry, the problem of air quality degradation has become more and more prominent. In order to ensure the quality of indoor air, many air filtration and purification products have been launched on the market, among which air filters are relatively common products. Existing filters are combined with particulate matter and odor removal filters, but the functions of split air filters are relatively independent and cannot form a complete filter system. The assembly process is also relatively cumbersome, and often fails due to improper assembly. Affect the purification efficiency; in addition, the service life of the filter cannot be displayed directly, which affects the use effect of consumers. [0003] In view of this, the present invention is proposed. ...
