Abstract

The invention discloses an autolysis type strong self-adhesion elastic bandage. The autolysis type strong self-adhesion elastic bandage comprises autolysis type elastic bandage base cloth and a graphene modified natural latex adhesive, the graphene modified natural latex adhesive is positioned on the surface of the autolysis type elastic bandage base cloth. The invention further discloses a method for preparing the autolysis type strong self-adhesion elastic bandage. More epoxy active sites are introduced to the graphene oxide, protein in natural latex is rapidly adsorbed, the epoxy active sites and amino groups in the protein in the natural latex are subjected to an epoxy ring-opening reaction, the nitrogen content in the natural latex is reduced, allergy is avoided, the adhesive strength and the solid content are better, and the preparation method is simple. Chitosan, polyethylene glycol and an inorganic nano-material graphene oxide are used as raw materials and have good autolysis, chitosan and graphene have bactericidal performance, and chitosan can rapidly stop bleeding, relieve pain and promote wound healing, so that the obtained self-adhesive elastic bandage has good strong viscosity, autolysis and antibacterial effects.

Description

technical field [0001] The invention relates to the technical field of bandages, in particular to a self-dissolving strong self-adhesive elastic bandage and a preparation method thereof. Background technique [0002] As a common dressing, bandages are widely used in the medical field for postoperative wound dressing, fixation, and dressing of injured parts during sports. They mainly perform special functions such as support, protection, and orthopedics. High, it is easy to adhere to the wound during use, aggravating the injury and causing new wounds to appear. When it is removed, it will be removed together with the hair on the skin, which greatly reduces the user's experience. At the same time, it needs other fixed products to fix it. , causing inconvenience in use, therefore, self-adhesive elastic bandages are developed and used. Self-adhesive elastic bandages are a special elastic bandage, which has a certain degree of self-adhesiveness and elasticity, and can be self-win...
