Problems solved by technology

The accumulation of dust in the evaporator and condenser of the air conditioner reduces the heat exchange efficiency and cooling effect, prolongs the cooling time, increases fuel consumption, and shortens the service life of the air conditioner
And the plastic parts in the car will also release a large amount of toxic and harmful gases, seriously endangering the health of drivers and passengers
[0004] At present, people use the method of regularly replacing the filter element to remove the bacteria that grow on the filter element in the car air conditioner, and the replacement time of the filter element is about once every six months. Bacteria re-grow, and the bacteria grow explosively, and the time limit is short. The method to remove the irritating gas in the car interior is to open the window and discharge harmful gas into the air. When the ambient temperature is too high or too low, this emission will The way is limited, or to buy absorbent substances to absorb harmful gases, this method is more troublesome

Abstract

The invention relates to the technical field of automobile air conditioner assemblies and in particular relates to an automobile air conditioner filter element for degrading formaldehyde and a preparation method of the automobile air conditioner filter element. The preparation method comprises the steps: firstly, carrying out a hydrothermal reaction to prepare a titanium dioxide / graphene degradation catalyst, and compounding the degradation catalyst with activated carbon to obtain a compound light degradation catalyst; and after uniformly mixing the compound light degradation catalyst in a polymer emulsion, carrying out electrostatic spinning to prepare functional fiber, and carrying out spinning and subsequent treatment on the functional fiber to obtain a self-cleaning filter element for an automobile air conditioner. The self-cleaning filter element contains functional compound ionic titanium dioxide / graphene which is capable of killing bacteria in an environment, also degrading formaldehyde in the environment in the presence of ultraviolet rays and avoiding self-consumption and long in acting time.

Description
