Problems solved by technology

The existing air filter membranes are relatively thick. In order to increase the specific surface area and increase the dust holding capacity, the thickness of the air filter membrane reaches 6 to 7 cm, and the thinnest one is 3 to 4 cm; and usually the function is relatively single, only PM10 can be removed , PM2.5 and formaldehyde; in order to increase the function of the air filter membrane, other materials or substances are usually added to increase the thickness of the air filter membrane; making the air filter membrane impossible to install in a small space such as air conditioners and air conditioning fans , it needs to be used together with an air purifier. The existing air purifier usually occupies a certain space and has high maintenance costs. It is difficult to meet the needs of the general public, and its use is subject to certain restrictions.

Description

Technical field [0001] The present invention relates to the field of membrane technology, specifically a 360 ° flexible air purification material and a preparation method thereof. Background [0002] Indoor air purification technology mainly relies on materials such as air filtration membrane or air filtration membrane mesh to physically block gaseous pollutants. There are many types of pollutants in the air, which requires the filtration membrane to be able to remove a variety of pollutants while ensuring a certain amount of air flux. Therefore, the filter membrane must have the functions of porosity, high capture efficiency, and removal of multiple contaminants. In commercial filter membrane materials, PP, glass fibers and their derivatives are used to manufacture air filtration membranes. The existing air filtration membrane is relatively thick, in order to increase the specific surface area and increase the amount of dust, the thickness of the air filtration membrane reaches ...
