Description
Technical Field
The invention belongs to the technical field of air filtering materials, and particularly relates to a recyclable, efficient, low-resistance, antibacterial and anti-haze air filtering material and a preparation method thereof.
Background
In recent years, with the progress of science and technology and the continuous development of industry, the problem of the quality reduction of ambient air caused by environmental pollution is increasingly serious due to the rapid economic growth. The environmental monitoring center has increased detection strength on PM10 (respirable particles, particles with the diameter less than or equal to 10 micrometers in the atmosphere) and PM2.5 (particles capable of entering lung and particles with the diameter less than or equal to 2.5 micrometers in the atmosphere), and in urban areas such as North China and east China at present, the content of PM2.5 in the atmosphere is seriously exceeded, which causes well-known dust-haze weather and serious harm to human health. PM2.5 particles are carriers with good toxic and harmful substances in the air, and can directly enter human lungs without blockage, so that the incidence of diseases such as lung cancer is greatly increased. Control and protection of PM2.5 is critical to human health and the harmonious development of human society. With the progress of science and technology and the deterioration of ecological environment, bacteria and viruses in life and medicine do not harm human health for a long time. Generally, the diameter of the virus is about 200nm, so that the aim of rationalization is difficult to achieve by adopting a pure air filtering material for filtering, and therefore, the development of antibacterial and antivirus materials is necessary to solve the harm of bacteria and virus to human beings. The antibacterial agent is attached to the fiber filter material by a specific method, and is combined with bacteria and viruses in the air in the filtering process to achieve the purpose of killing the germs and protecting the health of human beings. Air filtration articles such as masks, air filters, gas masks, and the like are increasingly gaining importance in maintaining human green life and physical health. The air filtering material must have the functions of intercepting solid harmful substances in the air or generating adsorption reaction with the solid harmful substances, and the like, so that the purposes of purifying the air and ensuring the health of human beings can be achieved. At present, daily and medical air filtering materials in the market, such as masks, face masks, protective clothing and the like, are mostly made of non-woven fabrics, and most of the materials do not have good antibacterial performance. Although the material has the advantages of simple production process, mass production and the like, the material is generally hard and rough in texture, has low filtering efficiency on smaller particles in the air, lacks functions of resisting virus, sterilizing and the like, has poor filtering capability on oily substances which are difficult to filter in daily life of human beings, and cannot well protect the health of human beings in severe environment.
