Problems solved by technology

Second, a large amount of motor vehicle exhaust emissions will also produce a large amount of particulate matter, which has buried hidden dangers for the generation of haze weather
For example, Chinese patent document CN201610212835.2 discloses an electrospun nanofiber air filter material and its preparation method. The air filter material prepared by this method can only effectively filter particles, dust and impurities, and the micropores are easy to filter during the early stage. Blocked, poor air permeability, and secondly, its own antibacterial performance is not obvious. When applied to an air filter device, the function is single, and other purification methods need to be added as an auxiliary, resulting in increased energy consumption; when applied to a mask, it is directly in contact with the human body. Mouth-nose contact, antibacterial performance and comfort performance are weak, which can easily cause discomfort to the human body, so the existing air filter materials cannot meet the requirements of use

Description

technical field [0001] The invention belongs to the technical field of air purification, and relates to a preparation method of an antibacterial nanofiber air filter material. Background technique [0002] In recent years, my country has suffered from continuous smog weather, the number of provinces and cities affected has continued to increase, and the number of heavily polluted areas has also continued to increase. According to reports, there are many reasons for the large-scale and long-lasting smog weather in China, but the most important and direct reasons are two: one is the meteorological conditions for the formation of smog, and the other is the artificial formation of smog. reason. Man-made reasons mainly include the following: First, the large-scale use of fossil dyes in factories, thermal power plants and chemical plants with coal combustion as the main energy structure will produce a lot of particulate matter; Gold, mechanical and electrical manufacturing, as w...
