Technical Field

The invention relates to the technical field of air bactericides, in particular to a layered solid acid air bactericide, and a preparation method and application thereof.

Background

Air is an important transmission path of microorganisms such as bacteria and viruses, and is always subjected to harm from the bacteria and the viruses in the air in our working and living places, wherein the variety and the number of the microorganisms in indoor air have particularly profound influence on human health. Generally, the content of bacteria and viruses in indoor air is 5-10 times higher than that in outdoor air, and serious and even hundreds times higher. Bacteria and viruses in indoor air mainly originate from the following two aspects: firstly, the droplets can disperse microorganisms parasitizing the oral cavity and the throat of a person into the air in the form of droplets when the person breathes, speaks and sneezes deeply; and secondly, the average bacteria content of the scurf and the dust of the human body is calculated to reach 4 ten thousand, and the scurf and the dust can be suspended in the air to pollute the air along with the movement of the human body indoors, and particularly, when a patient is in the room, the corresponding pathogenic bacteria can be found in the air. Therefore, the air sterilization is an important means for controlling the spread of diseases and maintaining the health of human bodies.

The existing air sterilization technology has the defects of different types: ozone is used for air sterilization, ozone is toxic gas, and the excessive ozone can cause the respiratory system of a person to be obstructed, so that the ozone air sterilization device is required to be used in a sealing way, and the person can not stay in the environment with excessive ozone for too long time; plasma air sterilization is adopted, the system is complex and comprises a vacuum system, an exhaust filtering system, a plasma generating system and the like, the cost is high, and the plasma has great harm to human bodies and can be only used for sterilization in unmanned places; the negative ion air sterilization has an unobvious sterilization effect, the retention time of the negative ions in the air is short, the places with much dust are only retained for a few seconds, the negative ions are generated by high-voltage discharge, and a large amount of ozone is often generated during the high-voltage discharge, so that the human respiratory system is damaged; the photocatalyst air sterilization mainly utilizes ultraviolet light to irradiate the photocatalyst to generate the effect, and the ultraviolet light also has harm to human bodies.

Therefore, how to provide a novel air bactericide, which has no harm to human body, broad-spectrum bactericidal effect and low bactericidal cost, is a difficult problem to be solved urgently in the field.
