Abstract

The invention discloses a recyclable graphene composite melt-blown cloth with high filterability and a preparation method. The raw materials of the melt-blown cloth include, by mass percentage, 50%-99% of polypropylene slices, 0.1%-10% of graphene materials, 0.1%-1% of surfactant, 0.1% to 5% of additive, and 0.1%-49% of polypropylene staple fiber. The invention also provides a preparation method for the recyclable graphene composite melt-blown cloth with high filterability. The graphene composite melt-blown cloth prepared by the invention has excellent purification function, can be used in a filter layer of a mask to enhance the filtering efficiency, effectively reduces the particles, bacteria, viruses and other toxic and harmful substances contained in the inhalation environment, and canbe repeatedly used after washing to increas the service life of the product. At the same time, graphene has an antibacterial function, which can kill bacteria adsorbed on the filter. The recyclable graphene composite melt-blown cloth can also be used in air purifiers and the like to reduce toxic and harmful substances in indoor and car environments.

Description

technical field [0001] The invention relates to a graphene melt-blown cloth and a preparation method thereof, in particular to a graphene composite melt-blown cloth with recyclable high filterability and a preparation method. Background technique [0002] Graphene is a single-layer carbon atom material peeled off from graphite. Carbon atoms are tightly packed into a single-layer two-dimensional honeycomb lattice structure. It is the thinnest, hardest, and best-conducting material known to mankind. Material. Graphene has excellent mechanical, optical and electrical properties, and its structure is very stable. So far, researchers have not found the absence of carbon atoms in graphene. The links between carbon atoms are very flexible, harder than diamonds, and stronger than the world's The best steel is 100 times higher. If you use graphene to make a packaging bag, it will be able to bear about two tons of items, almost completely transparent, but extremely dense, impermeable...
