Problems solved by technology

[0004] At present, vacuum compression bags usually use plastic film to vacuum store clothes. Although it can effectively isolate the air and prevent bacteria in the air from contaminating the clothes, ordinary plastic films cannot kill various skin diseases, causing the clothes to be adsorbed and easily infected. Repeated infection of fungi or molds that affect people's life and health, solve the waste of special groups' clothes that can only be used once, and the environmental pollution after discarding

Abstract

The invention discloses a graphene antibacterial film and an air-exhaust-free cube vacuum compression bag. The graphene antibacterial film comprises 45-55 parts of graphene oxide, 25-30 parts of polyurethane resin, 15-20 parts of polyethersulfone resin, 10-15 parts of polytetrafluoroethylene resin, 8-10 parts of polyethylene resin, 50-60 parts of an organic solvent, 5-8 parts of a mugwort extract,2-5 parts of sodium carboxymethyl cellulose, 1-2 parts of tea polyphenol and 3-6 parts of a cationic nano-silver antibacterial agent. Graphene oxide powder is used as a raw material. The graphene oxide is used for resisting bacteria, the mugwort extract, the sodium carboxymethyl cellulose and the tea polyphenol are matched for resisting oxidation and preventing mildew, the structural stability isimproved, the mildew-proof and antibacterial functions of the vacuum compression bag are further guaranteed, and the requirements of more and more skin diseases for life hygiene and safety of peopleare met. The graphene antibacterial film is prepared by a uniform mixing and multi-layer co-extrusion process, and the vacuum compression bag is further prepared, so that the vacuum compression bag can effectively prevent mildew and inhibit bacteria in a vacuum state after being filled with clothes, quilts and other articles.
