Nanosilver disinfection antibacterial air filter element and preparation method thereof

Abstract

The invention provides a nanosilver disinfection antibacterial air filter element. A four-layer structure mode of a hydrophobic layer nanosilver disinfection antibacterial nonwoven fabric, activated carbon, an HEPA efficient filter screen and a hydrophilic layer nanosilver disinfection antibacterial nonwoven fabric is adopted, bacteria, viruses, toxic gases and the like in particles, an ash layerand liquid can be effectively filtered out, the filtering efficiency is improved, and the service life of the machine is prolonged; besides, nanosilver particles are materials with long-acting disinfection and antibacterial effects; the combination of the nanosilver and silver ions can achieve the effects of rapid sterilization and long-acting disinfection and antibiosis; the air filter element has good safety and long-term effect, the spherical nanosilver and the silver ions are loaded on a reticular fiber material of the air filter element, bacteria on the air filter element can be effectively killed, and long-term disinfection and antibiosis are realized, so that the air filter element is not easy to mildew and breed bacteria after being used for a long time. In addition, the inventionalso provides a preparation method of the nanosilver disinfection antibacterial air filter element.

Description

technical field [0001] The invention relates to the technical field of air filter elements, in particular to a nano-silver disinfection and antibacterial air filter element and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of the industrial economy, on the one hand, the living environment of human beings has been continuously challenged. Air pollution is one of the challenges. Air pollution seriously affects people's health; on the other hand, the development of medical, pharmaceutical and food industries There are also higher requirements for air cleanliness. [0003] Air filtration is currently the most effective way to deal with air quality problems, and filter materials are the core components, but now the traditional air filter element still has the following disadvantages: Traditional air filter elements generally use a three-layer structure of sponge-HEPA high-efficiency filter screen-sponge form, this traditi...

[0003] Air filtration is currently the most effective way to deal with air quality problems, and filter materials are the core components, but now the traditional air filter element still has the following disadvantages: Traditional air filter elements generally use a three-layer structure of sponge-HEPA high-efficiency filter screen-sponge form, this traditional air filter structure can effectively block harmful substances such as dust, particles, bacteria, and viruses in the air in the early stage, but as the use time increases, the air filter will inevitably produce a large amount of dust during use. Bacteria, bacterial reproduction will cause mildew on the air filter element, low filtration efficiency, easy to damage equipment, and does not have long-term disinfection and antibacterial effect, thus affecting the use of the air filter element, so the above-mentioned traditional air filter element needs to be used for a period of time For disinfection and antibacterial treatment, the operation is cumbersome and the process is complicated, which greatly increases the cost of materials and labor

In addition, some air filters have the function of disinfection and antibacterial by adding ultraviolet light inside. Although ultraviolet light can effectively achieve the effect of disinfection and antibacterial, it is easy to produce too much ozone, and ozone has a strong oxidation effect, which will affect the The human body produces damage and accelerates the aging of the surface of the object
