Anti-bacterial air filtering material containing graphene oxide material and applied to vehicles and preparation method of anti-bacterial air filtering material

Abstract

The invention discloses an anti-bacterial air filtering material containing a graphene oxide material and applied to vehicles and a preparation method of the anti-bacterial air filtering material. Theanti-bacterial air filtering material comprises an oxidized coconut carbon fiber layer, a graphene oxide fiber layer and a basalt fiber layer, wherein the graphene oxide fiber layer is arranged belowthe oxidized coconut carbon fiber layer; the basalt fiber layer is arranged below the graphene oxide fiber layer; the graphene oxide fiber layer is located between the coconut carbon fiber layer andthe basalt fiber layer; after the three layer structures are composited in sequence, anti-bacterial treatment is performed in a roll baking manner, and the anti-bacterial 3D air filtering material forthe vehicles is prepared. The technology is simple, large-scale automated production can be realized, the anti-bacterial air filtering material is better in anti-bacterial effect, and anti-bacterialrate for escherichia coli, staphylococcus aureus and bacillus subtilis exceeds 99.9%; besides, a long-term effect test result indicates that the anti-bacterial effect of the anti-bacterial material cannot be reduced obviously with prolongation of use time.

Description

technical field [0001] The invention relates to the field of air filter materials, in particular to a vehicle antibacterial air filter material containing graphene oxide material and a preparation method thereof. Background technique [0002] With the progress of society and the improvement of people's living standards, air filters are more and more widely used in various fields, such as pharmaceutical industry, hospital, food industry, cosmetic industry, environmental protection industry, etc. Compared with the world's advanced air filter materials, although my country's domestic filter materials can reach or even exceed their level in terms of filtration efficiency and other technical indicators, there is still a certain gap on the whole, which is mainly reflected in the poor uniformity of the filter materials. Antibacterial research is not systematic enough, in-depth. To a large extent, it limits the development level of filter equipment and is an urgent problem to be sol...
