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.
