Abstract

The invention belongs to the technical field of air purification materials, and particularly relates to an air purification material having a PM1.0 intercepting effect and deodorizing effect. The airpurification material has a three-dimensional netted layer porous structure formed by lap-joining graphene sheets, and the three-dimensional netted layer porous structure comprises large holes, mediumholes and small holes which are distributed randomly; a pore volume of a large hole is 0.05cm<3> / g to 1.05cm<3> / g, and the aperture is greater than 1000nm; the pore volume of the medium hole is 0.10cm<3> / g to 1.20cm<3> / g, and the aperture is 100 to 1000nm; and the pore volume of the small hole is 0.10cm<3> / g to 1.40cm<3> / g, and the aperture is smaller than 100nm. The surface and the interior of the air purification material provided by the invention have rich and complete layer hole structure, larger specific surface area and rich aperture distribution. By adopting the structure of the layerhole, the air purification material has the advantages of high purification efficiency, small airflow resistance and high deodorizing effect.

Description

technical field [0001] The invention belongs to the technical field of air purification materials, and in particular relates to an air purification material with both deodorization and PM1.0 interception effects and a preparation method thereof. Background technique [0002] With the development of industry, many large and medium-sized cities in China frequently produce smog weather, which seriously threatens people's health and lives. The mechanism of smog weather is very complicated, and its chemical composition is also very complicated. Viruses, germs, etc. may attach to the particulate matter in the atmosphere and cause various diseases. At the same time, a large amount of odors such as garbage, tobacco, toilets, and feet produced by human activities have seriously affected the normal production and life of human beings. The problem of how to efficiently clean up these air pollutants is seriously perplexing human beings. [0003] Generally speaking, particles with a par...
