Description

Graphene self-adhesive bandage
Technical Field
The invention relates to a graphene self-adhesive bandage.
Background
The self-adhesive bandage is an elastic bandage with self-adhesive property and good air permeability, and is often used in the industries of medical bandaging, sports protection and the like. The self-adhesive bandage on the market is mainly formed by coating glue which is prepared by taking natural latex or synthetic rubber as a main component, the natural rubber has high content of antigen protein and is easy to mildew, and the synthetic rubber has the problem of organic matter pollution. As a novel material, the graphene not only has excellent optical, electrical, thermal, force and other properties, but also has the effects of antibiosis, far infrared emission, ultraviolet resistance and the like.
The natural latex has great cohesion, high self-adhesion and poor adhesion with polar substances. Conventional tackifiers increase adhesion to polar substrates by changing the polarity of the natural latex, thereby decreasing cohesion.
Disclosure of Invention
The invention aims to provide a graphene self-adhesive bandage aiming at the defects of the prior art.
The invention adopts the following technical scheme: a graphene self-adhesive bandage is composed of a graphene elastic base cloth and graphene glue coated on two sides of the graphene elastic base cloth. The graphene elastic base cloth is made of cotton fibers coated by a graphene-polymer composite material, and the surfaces of the composite fibers are provided with regular filament arcs. The graphene glue is composed of 80-90 parts of natural latex, 3-5 parts of a flatting agent and 0.01-10 parts of graphene.
Further, the preparation method of the graphene elastic base cloth comprises the following steps: and (2) slicing the graphene and a monomer after copolymerization, or slicing the graphene and a polymer after blending, then carrying out coaxial spinning with cotton fibers, constructing regular filament arcs on the surfaces of the fibers by adopting an air deformation process in the spinning process, and then manufacturing the base fabric.
Further, the graphene is one or more of single-layer graphene, double-layer graphene, multi-layer graphene, oxidized graphene, fluorinated graphene, sulfonated graphene and the like.
Further, the polymer is one or more of nylon 6, nylon 66, PET, spandex, aramid fiber, polypropylene fiber and the like.
Further, the coating method of the graphene glue is one or more of blade coating, spraying and dip coating.
Compared with the prior art, the invention has the following beneficial effects:
(1) the natural latex has great cohesion, high self-adhesion and poor adhesion with polar substances. Conventional tackifiers increase adhesion to polar substrates by changing the polarity of the natural latex, thereby decreasing cohesion. According to the invention, the graphene is added into the natural latex, and the natural latex is divided into countless small islands, so that the cohesion and self-adhesion of the natural latex are reduced, the adhesion on other substances is improved, and the graphene glue used in the self-adhesive bandage system can be well applied on the base cloth. On the other hand, the graphene serving as the tackifier can also avoid the smell brought by the traditional tackifier, so that the cost is reduced, and the occurrence of allergy is reduced.
(2) Natural latex generally contains proteins and sugars, and is easily mildewed by microorganisms or enzymes. The addition of the graphene can destroy bacterial cell membranes, extract phospholipid molecules on the cell membranes, enable the cells not to survive, solve the problem that self-adhesive bandages of natural latex systems are easy to mildew, endow the self-adhesive bandages with certain antibacterial performance, and be more beneficial to the application of the self-adhesive bandages in the medical industry. Amine preservative is not needed, pungent smell is avoided, and the operation environment is greatly optimized.
(3) The graphene absorbs high-energy ultraviolet rays and then is converted into a fluorescent, phosphorescent or thermal form to be released, so that the aging resistance of the self-adhesive bandage is improved, and the problem that the self-adhesive bandage degrades and is sticky after being stored for a long time is solved.
The graphene elastic cloth is made of fancy fibers spun by graphene-polymer composite materials and cotton fibers through an air deformation process, and the surface of the graphene elastic cloth is provided with regular filament arcs, so that glue can be adhered to the surface of the base cloth, and the glue application amount and the uniformity of the glue can be better controlled.
(4) The graphene is added into the elastic base cloth and the glue, so that the self-adhesive bandage is endowed with an excellent far infrared emission function, the capillary vessels are expanded, the blood circulation is promoted, the metabolism among tissues is strengthened, the regeneration capacity of the tissues is increased, and the self-adhesive bandage can promote the recovery of injured tissues while playing a role in fixation.
