Substrate for medical adhesive tapes and preparation method thereof

Abstract

The invention relates to a substrate for medical adhesive tapes and a preparation method thereof and belongs to the technical field of medical materials. The substrate for medical adhesive tapes comprises the following components in parts by weight: 20-32 parts of polyisobutylene, 12-18 parts of PET resin, 5-10 parts of glass fiber, 1-3 parts of 10-hydroxy-2-decenoic acid, 6-12 parts of nano silicon dioxide, 1-4 parts of tri[2,4-di-tert-butylphenyl]phosphate, 7-15 parts of a citric acid, 1-5 parts of zinc stearate, 2-5 parts of tri-n-butyl citrate, and 4-10 parts of polyethylenimine. The substrate for medical adhesive tapes disclosed by the invention has excellent air permeability, and if a medical adhesive tape is in contact with the skin, the medical adhesive tape can keep the skin refreshing and ventilated; the substrate for medical adhesive tapes disclosed by the invention can endow an adhesive tape with good tearability, so that the adhesive tape is easy to use; the substrate for medical adhesive tapes disclosed by the invention has good antibacterial properties; and fourthly, the preparation method disclosed by the invention is simple and practicable, convenient to implement, and suitable for large-scale popularization and application.

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.
