Description

technical field [0001] The invention belongs to the technical field of medical materials, and in particular relates to a substrate for medical adhesive tape and a preparation method thereof. Background technique [0002] Adhesive tape is composed of base material and adhesive. Two or more unconnected objects are connected together by bonding, and a layer of adhesive is coated on the surface of the base material. The earliest adhesives came from animals and plants. In the nineteenth century, rubber was the main component of adhesives. With the continuous development of industry, various polymers have become the main components of adhesives. Adhesives can stick to things because of the formation of bonds between their own molecules and the molecules of the objects to be connected, and this bond can firmly bind the molecules together. The performance of the tape substrate also has an important impact on the performance of the tape. [0003] Medical tapes are used in a wide ...
