Functional air filtering material

Abstract

The invention provides a functional air filtering material. The functional air filtering material is formed by compounding a base material and an antibacterial electrostatic spinning nanofiber layer, wherein an antibacterial agent in the antibacterial electrostatic spinning nanofiber layer is a biological bactericide. According to the functional air filtering material provided by the invention, a spinning solution added with the biological bactericide is spun on the base material by adopting an electrostatic spinning preparation process. The air filtering material provided by the invention has the advantages of high flexibility, small fiber diameter, high porosity, uniform distribution of pore diameter, light weight, high permeability, high environment-friendly property and remarkable filtering effect.

Description

technical field [0001] The invention relates to the field of materials, in particular to a functional air filter material. Background technique [0002] In recent years, my country's industrialization has developed rapidly, and the speed of urbanization has continued to accelerate. Various pollution problems have emerged one after another, among which air pollution has become a major problem of current environmental pollution. Factory exhaust, automobile exhaust, construction dust, and residents' lives emit a large amount of soot particles, and these particles also provide a carrier for bacteria to grow and reproduce. These will not only seriously threaten people's health, but also have adverse effects on the natural climate, destroying the natural environment on which animals and plants depend. On January 4, 2014, the National Disaster Reduction Office and the Ministry of Civil Affairs notified the natural disasters in 2013, including smog for the first time. Therefore, d...

Problems solved by technology

For particles with a size above the micron level, the traditional nonwoven mask filter cloth can have better filtering performance, but for the particulate matter or bacteria with a size of submicron or even nanometer level, the traditional nonwoven mask filter cloth has poor filtering performance. , and there are very few air filter materials with antibacterial functions

[0003] But in the prior art, the antibacterial agent that is used for the antibacterial type air filter material of mouth mask mostly adds is organic antibacterial agent or inorganic antibacterial agent, and there is certain risk in environmental protection, therefore, develops a kind of efficient and practical nontoxic antibacterial type air Purification material is very necessary
