Problems solved by technology

[0004] At present, the commonly used method of getting out of the irritating gas in the car room is to open the window and discharge the harmful gas into the air. When the ambient temperature is too high or too low, this discharge method is restricted, or the purchase of an adsorbent The substances adsorb harmful gases, this method is more troublesome

Abstract

The invention relates to the technical field of automobile air conditioner assemblies, in particular to an antibacterial filter element for an automobile air conditioner and a preparation process of the antibacterial filter element. The preparation method of the antibacterial filter element for the automobile air conditioner comprises steps as follows: (1) plants are put in a muffle furnace to becarbonized, and activated carbon is obtained; (2) a metal compound and a ligand are mixed uniformly under the water-containing condition, alkaline substances and the activated carbon are added and stirred until the solution is in a gel state, B sources are added, the mixture is mixed uniformly, dried and calcined, and magnetic nanoparticles are obtained; (3) the magnetic nanoparticles, Chinese herbal medicine powder and a negative ion additive are added to a solvent and mixed uniformly, and a mixture 1 is obtained; (4) the mixture 1 and a high-molecular polymer are mixed and cured, and the antibacterial filter element for the automobile air conditioner is prepared. The antibacterial filter element for the automobile air conditioner has the excellent antibacterial, sterilization, mite killing and disinfecting functions, cannot produce peculiar smells in the use process and has the effect of adsorbing and degrading harmful gas.

Description

technical field [0001] The invention relates to the technical field of automobile air-conditioning components, in particular to an antibacterial filter element for automobile air-conditioning and a preparation process thereof. Background technique [0002] Automobile air conditioner is already an essential part of existing automobiles. Generally, it mainly consists of a compressor, an electronically controlled clutch, a condenser, an evaporator, an expansion valve, a liquid storage dryer, a pipeline, a condensing fan, a vacuum solenoid valve, an idler and The composition of the control system. The main functions of the existing automobile air conditioners are as follows: (1) it can control the temperature in the compartment, it can not only heat the air, but also cool the air, so that the temperature in the compartment can be controlled to a comfortable level; (2) it can discharge the air (3) It can inhale fresh air and has a ventilation function; (4) It can filter the air ...
