PM2.5 vehicle-mounted air filter material and preparation method thereof

Abstract

The invention relates to a PM2.5 vehicle-mounted air filter material and a preparation method thereof, the PM2.5 vehicle-mounted air filter material comprises a pre-filter layer, a peculiar smell purification layer, a medium-efficiency ash containing layer, a high-efficiency filter layer and a support protective layer; wherein the pre-filter layer, the peculiar smell purification layer, the medium-efficiency ash containing layer, the high-efficiency filter layer and the support protective layer are laminated and compounded into a whole; sterilization particles are immersed in both the pre-filtering layer and the supporting protection layer. The method comprises the steps that S1, a supporting protection layer, an efficient filtering layer and a medium-efficiency ash containing layer are conveyed into a hot press; S2, the composite supporting layer is conveyed into a punching die; S3, each accommodating groove is filled with a purification filling material; S4, the pre-filtering layer is laid on the composite supporting layer. By means of the multi-layer composite filter material, the efficiency of 0.3 micron particles can be improved, meanwhile, the low air inlet resistance is met,and the effects of inhibition and killing of bacteria, efficient removal of peculiar smells and high dust containing are achieved.

Description

technical field [0001] The invention belongs to the technical field of filters, in particular to a PM2.5 vehicle-mounted air filter material and a preparation method thereof. Background technique [0002] The car air conditioner filter element plays a vital role in purifying the fresh air entering the car interior. Dirty air not only affects passengers' feelings, but also threatens their physical and mental health. [0003] Studies have shown that PM2.5 (particulate matter with a particle size below 2.5um) has the most direct impact on the human respiratory tract. Particles with this particle size can directly pass through the protective layer of the human respiratory tract and enter the human body, causing harm to the human body. The particle size of the virus is between 0.08 and 0.12um, but they are all attached to the carrier for transmission, such as water vapor in the air, aerosol, smog, droplets, etc., and these carriers Generally, the particle size is larger than 0....

AI Technical Summary

Problems solved by technology

The particle size of the virus is between 0.08 and 0.12um, but they are all attached to the carrier for transmission, such as water vapor in the air, aerosol, smog, droplets, etc., and these carriers Generally, the particle size is greater than 0.3um. The current filter material has limited filtration capacity and cannot effectively filter out PM2.5.
