Problems solved by technology

However, the current band-aid should not be used for too long, because the adhesive tape on the outer layer of the band-aid is airtight, and if used for too long, the wound and the skin around the wound will turn white and soften, resulting in secondary infection of bacteria, which will make the wound more serious. deterioration

Abstract

The invention relates to adhesive for an adhesive bandage and a preparation method of the adhesive and belongs to the technical field of medical materials. The adhesive for the adhesive bandage is prepared from, by mass, 20-40 parts of epoxy resin, 15-25 parts of alicyclic amine, 5-10 parts of n-dodecyl glycidyl ether, 1-5 parts of sodium carboxymethylcellulose, 0.2-1 part of nano-zinc oxide, 0.5-2 parts of silica gel, 1-3 parts of dibutyl phthalate, 0.1-0.5 part of talcum powder, 0.1-0.3 part of chitin and 2-8 parts of ethanediol. The adhesive for the adhesive bandage is nontoxic and nonhazardous, has a good antibacterial function, meets the medical level and is good in air permeability and waterproofness; the preparation method of the adhesive is simple and convenient and is suitable for large-scale application and popularization.

Description

technical field [0001] The invention belongs to the technical field of medical materials, and in particular relates to an adhesive for band-aids and a preparation method thereof. Background technique [0002] Adhesive is a natural or synthetic, organic or inorganic substance that can connect two or more parts or materials together through interface adhesion and cohesion. Adhesives, also known as adhesives, are customarily referred to as glue. In short, an adhesive is a substance that can bind adherends together through bonding. "Adhesive" is a general standard term that also includes other glues, putties, mucilages, plasters, etc. [0003] Band-aid is the most commonly used surgical drug in people's life. Band-aid, also known as "hemostatic plaster", has the effect of stopping bleeding and protecting wounds. It consists of a long strip of adhesive plaster with a small piece of drug-soaked gauze attached in the middle. This requires the adhesive on the tape to have good ...
