Abstract

The invention discloses a graphene composite antibacterial and antiviral polypropylene filament and a preparation method thereof. The graphene composite antibacterial and antiviral polypropylene filament comprises the following raw materials by mass percentage: 90-95% of propylene monomer, 0.1-9% of graphene material, 0.1-5% of first modifier, 0.1-5% of second modifier and 0.1-1% of catalysts. Theinvention also provides a preparation method of the graphene composite antibacterial and antiviral polypropylene filament. According to the invention, modified graphene polypropylene filament fiberswith antibacterial, antiviral and formaldehyde removal functions can be prepared, the added value of the polypropylene fibers is improved, and the application range of the polypropylene fibers is extended; and graphene in the prepared in-situ polymerized modified graphene polypropylene filament fibers is uniformly dispersed and is not easy to fall off, so that the functions are long-lasting, the performance is excellent, and the graphene composite antibacterial and antiviral polypropylene filament can meet the current market requirements for functionalized graphene polypropylene filament fibers, and has broad application prospects.

Description

technical field [0001] The invention relates to a graphene composite polypropylene filament and a preparation method thereof, in particular to a graphene composite antibacterial and antiviral polypropylene filament and a preparation method thereof. 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 extre...
