Abstract

The invention relates to a graphene efficient air purifier filter material and a preparation method. The graphene efficient air purifier filter material is prepared from 100 parts by mass of modifiedloofah sponge, and 20-30 parts by mass of a graphene material. The filter material is further prepared from 2-5 parts by mass of a nano catalytic material. The preparation method comprises the following steps: preparing the modified loofah sponge, preparing graphene material dispersion liquid, and preparing the graphene filter material. According to the prepared air purifier filter material, a vascular bundle of the used loofah sponge has the elasticity, has a network gap, and is capable of achieving a support function to the graphene material. The graphene material attached to the loofah sponge is self-assembled to form an aerogel structure which can realize the sterilizing anti-bacterial effects. The nano photocatalytic material wrapped in graphene aerogel is capable of degrading organicpollutants of formaldehyde and methyl orange and the like under the photocatalytic effect, and in the case of guaranteeing the filtering effect, effectively prolonging the service life of the filtermaterial.

Description

Technical field [0001] The invention relates to the field of air purification materials, in particular to a graphene high-efficiency air purifier filter material and a preparation method. Background technique [0002] Some existing air filters have at least 3 layers of filters, which are pre-filters, activated carbon filters, and dust-collecting filters (HEPA filters). The pre-filters are newly developed micro-mesh dust filters. Net, the mesh area is smaller than normal, in addition to adsorbing small dust particles, it also effectively removes hair. The surface is cleaned with a fluoxone treatment, and the dust on the surface of the filter screen can be more easily cleaned; activated carbon is a black amorphous granular or fine powder. In air purifier products, they generally exist in the form of particles. Activated carbon particles have a large surface area, and there are abundant micropores all over the body. Its chemical properties determine that it has a strong adsorption...
