Abstract

The invention relates to a medical antibacterial adhesive and a preparation method thereof, and belongs to the technical field of adhesives. The medical antibacterial adhesive comprises the following constituents in parts by weight: 16 to 20 parts of epoxy resin, 2 to 10 parts of crylic acid, 4 to 10 parts of editic acid, 12 to 18 parts of polyurethane, 2 to 5 parts of polyvinyl alcohol, 2 to 8 parts of methylol cellulose, 1 to 3 parts of citric acid, 3 to 9 parts of nanometer silicon micro powder, 10 to 14 parts of titanium dioxide, and 20 to 30 parts of glycol. The medical antibacterial adhesive has good bonding property, and can rapidly realize bonding even at low temperature; the medical antibacterial adhesive has excellent antibacterial property; the preparation method is simple, convenient to carry out, and suitable for large-scale promotion and application.

Description

technical field [0001] The invention belongs to the technical field of adhesives, and in particular relates to a medical antibacterial adhesive and a preparation method thereof. Background technique [0002] At present, medical adhesives play a very important role in clinical practice. In surgical operations, medical adhesives are used for local bonding and repair of certain organs and tissues; in orthopedic surgery, the combination and positioning of bones and joints, and in dental surgery for tooth repair. From the application objects and performance requirements of medical adhesives, it can be divided into dental adhesives and shell adhesives. The above-mentioned adhesives should generally meet the requirements of being safe, non-toxic, non-carcinogenic, teratogenic, and mutagenic; Good antibacterial properties. The application of medical adhesives is subdivided into soft tissue adhesives, α-cyanoacrylate adhesives, fibrin adhesives, hard tissue adhesives, orthopedic...
