Abstract

The present invention provides an air filter material that can be sterilized by electric heat in situ. The air filter material that can be sterilized by electric heat in situ includes auxiliary fibers, filter fibers and adhesives. The auxiliary fibers are chopped carbon fibers. And the fiber diameter range of the carbon fiber is 0.2-1.2 μm, the fiber length range is 1-15mm, the filter fiber adopts one or more of glass microfiber cotton, plant fiber and chemical fiber, and the filter fiber The degree of beating and knocking is ≥19 degrees, and the adhesive uses one or more of melamine formaldehyde resin, polyacrylic acid emulsion, and styrene-acrylic emulsion. By adopting the above scheme, the obtained air filter material has high-quality filtering ability, which can reach medium and high-efficiency filtering levels. Secondly, the air filter material has excellent electric heating ability, which can significantly improve the disinfecting efficiency and quality under electric heating conditions, effectively To prevent harmful microorganisms from accumulating inside the air filter material.

Description

Technical field: [0001] The invention relates to the technical field of air filtration, in particular to an air filter material capable of in-situ electrothermal sterilization and a preparation method. Background technique: [0002] With the continuous progress of society, the epidemic virus that has a deep symbiotic relationship with human society is also constantly mutating, especially when people are highly mobile. Once there is a large-scale outbreak, such as the current new crown epidemic, it seriously threatens Human life is safe. It is often difficult to effectively cure such epidemics, especially when there is a lack of specific drugs, and it is necessary to prepare for long-term epidemic prevention and control. Currently, for diseases similar to the new coronavirus, the source of infection is viruses, bacteria and other microorganisms, the use of filter materials can Effective protection, such as PP melt-blown cloth used in medical masks, glass fiber filter materia...
