Problems solved by technology

However, after a period of time, the car air conditioner filter will attach and breed a large number of pathogenic microorganisms, which will enter the car with the air flow and affect human health; mold will also grow on the car air conditioner filter , resulting in odor
However, non-woven fabrics, filter paper and activated carbon have no bactericidal effect, and cannot solve the problem of bacteria and mold

Embodiment 1

[0021] The skeleton non-woven fabric and the melt-blown non-woven fabric are compounded with hot melt adhesive, folded and formed, and the frame is installed to make an automobile air conditioning filter. Through the test, the filtration efficiency of PM2.5 reaches more than 99%.

Embodiment 2

[0023] The melt-blown non-woven fabric and the activated carbon layer are compounded with hot-melt adhesive, folded and formed, and the frame is installed to make an automobile air conditioning filter. When in use, the air first passes through the melt-blown non-woven fabric, and then through activated carbon, which can remove PM2.5 and odorous organic matter. Through the test, the filtration efficiency of PM2.5 reaches more than 99%.

Embodiment 3

[0025] The antibacterial non-woven fabric and the melt-blown non-woven fabric are compounded with hot melt, folded and formed, and the frame is installed to make an automobile air conditioning filter. Preparation of antibacterial non-woven fabric: Take 30 grams of polyhexamethylene (bi)guanidine hydrochloride as an antibacterial agent and place it in 2 liters of water, stir at high speed at room temperature, and add 50 grams of povidone K30 as an adhesive and stir for half hour, spread the mixed solution on a non-woven fabric with a porous structure, and dry to obtain an antibacterial non-woven fabric. When in use, the air first passes through the antibacterial non-woven fabric, and then through the melt-blown non-woven fabric, which can remove PM2.5 and bacteria. The automotive air-conditioning filter made of the antibacterial non-woven fabric was replaced in the car and used for 30 days, then removed, and the number of colonies on the surface of the filter screen was detecte...

Abstract

The invention discloses a multilayer-structure antibiotic automobile air conditioner filter capable of filtering PM2.5. The multilayer-structure antibiotic automobile air conditioner filter capable of filtering PM2.5 comprises a frame body and a filter element, wherein the filter element is made of melt-blown non-woven fabric, preferably an antibiotic melt-blown non-woven fabric which is prepared by adding antibacterial master batches into a melt-blown non-woven fabric polymer and then performing melt-blowing extrusion. According to the multilayer-structure antibiotic automobile air conditioner filter, multiple times of screening are performed, so that the technical problems of low filtration efficiency, wind resistance and the like are overcome; the melt-blown non-woven fabric is applied to the automobile air conditioner filter for the first time, and a static electricity technology is combined, so that the PM2.5 problem is effectively solved. Meanwhile, by virtue of a mode of adding the antibacterial master batches into the melt-blown non-woven fabric or compounding an antibiotic non-woven fabric with the melt-blown non-woven fabric, the bacterium problem is solved; an active carbon layer is arranged for solving the problems of smell and organic matters. Correspondingly, the multilayer-structure automobile air conditioner filter can be used for various problems of purification of an automobile air conditioner, is capable of resisting PM2.5, bacteria, organic matters, peculiar smell and the like, and has quite wide application prospect.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a filter capable of filtering PM2.5 [0002] The multi-layer structure antibacterial automotive air conditioning filter. Background technique [0003] Automobiles have become an indispensable means of transportation for people's daily life. In the closed environment of the car, when using the air conditioner to adjust the temperature inside the car, if no filtering measures are used, it is impossible to filter out dust, remove odors, bacteria and other harmful substances; in such an environment for a long time, it is bound to have adverse effects on the human body. influences. The nationwide smog weather this year has caused many health problems, and how to solve PM2.5 is an air problem that people pay special attention to. [0004] Existing ordinary automotive air conditioning filters all use non-woven fabric or filter paper as the filter element, and non-woven fabric and filter pap...
