Abstract

The invention discloses a medical adhesive tape which comprises an adhesive tape layer, a bonding layer and a back lining layer which are sequentially and tightly bonded. The bonding layer is prepared from the following raw materials in parts by weight: 30-40 parts of polyethylene, 0.5-0.6 part of sodium citrate, 18-25 parts of ethyl acrylate, 1-3 parts of dimethyl diphenylamine, 3-9 parts of olive oil, 5-15 parts of costus root, 2-6 parts of ricepaper pith, 1-3 parts of mint, 2-4 parts of chrysanthemum flower and 2-4 parts of aconitum fischeri peichb. The preparation method of the bonding layer comprises the following steps: uniformly grinding and mixing the costus root, ricepaper pith, mint, chrysanthemum flower and aconitum fischeri peichb; carrying out extraction by using ethanol, carrying out vacuum evaporation on the extract to obtain powder, uniformly mixing with the polyethylene, sodium citrate, ethyl acrylate, dimethyl diphenylamine and olive oil, applying a pressure of 5-10 MPa, treating under the microwave power of 100W for 1 hour, and cooling to obtain the bonding layer. The medical adhesive tape is simple to implement. The adhesive tape has the advantages of favorable bonding property and higher antibacterial durability, so the practicality of the adhesive tape is greatly enhanced.

Description

technical field [0001] The invention relates to the technical field of materials, in particular to a medical adhesive tape. Background technique [0002] Usually, people use adhesive plaster when treating and bandaging wounds after surgical sutures. Due to the high production cost of adhesive plaster, but the air permeability and bonding performance are relatively general, it is gradually being used in medical institutions. Woven tape instead. [0003] Ordinary non-woven tapes have excellent air permeability, stretchability and bonding performance, are non-toxic, non-irritating, and non-allergic to the skin, and have moderate preparation costs and high practicability. However, non-woven tapes are usually single- or double-layer fabrics with limited antimicrobial properties. Especially for some occasions that need to be fixed with tape for a long time, such as: children hang water continuously, the needle generally needs to be fixed with tape for 4-5 days, bacteria are easy...
