Problems solved by technology

However, during the cycle of the car air conditioner, the smoke in the car, human sweat, and dust are all gathered on the surface of the humid evaporator, which is prone to odor. These harmful substances, along with the air circulation in the car, enter the human body through breathing, causing respiratory system infection, lowering the body's resistance, and severe symptoms such as dizziness, fatigue, and nausea, especially for the elderly and children Very dangerous
When bacteria accumulate and multiply on the evaporator and condenser of the air conditioner, the heat exchange efficiency and cooling effect will be reduced, the cooling time will be prolonged, the fuel consumption will increase, and the service life of the air conditioner will be shortened.
[0003] 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, which cannot effectively solve the bacterial infestation

Abstract

The invention relates to the technical field of automobile spare parts, in particular to an automobile air conditioner antibacterial filter element and a preparation method thereof. The preparation method comprises the following steps: making starch and sodium phytate react to obtain starch-sodium phytate nanoparticles; adsorbing and modifying the starch-sodium phytate nanoparticles with diatomaceous earth to obtain modified starch-sodium phytate nanoparticles; compounding the modified starch-sodium phytate nanoparticles are with graphene-modified amoxicillin to obtain a composite bactericide;pulping wood pulp fiber, then adding a catalyst and conducting sheet making and drying to obtain the then the sheet is dried and dried to obtain the automobile air conditioner antibacterial filter element. The automobile air conditioner antibacterial filter element has long-acting antibacterial effects, has no toxic and side effects on human body safety, and is environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to an antibacterial filter element for an auto air conditioner and a preparation method thereof. Background technique [0002] With the development of social economy, automobiles have become a common means of transportation. Automobile air conditioners are an indispensable part of existing automobiles. Provide a comfortable environment for the staff. However, during the cycle of the car air conditioner, the smoke in the car, human sweat, and dust are all gathered on the surface of the humid evaporator, which is prone to odor. These harmful substances, along with the air circulation in the car, enter the human body through breathing, causing respiratory system infection, lowering the body's resistance, and severe symptoms such as dizziness, fatigue, and nausea, especially for the elderly and children The danger is particularly great. When bacteria accumulate and multiply on the...
