Problems solved by technology

Compared with traditional medical elastic bandages in the past, natural latex self-adhesive elastic bandages have the advantages of convenient fixing, good air permeability, non-sticky hair, non-sticky skin, comfortable and smooth dressing, and wide application. Contains protein. Researchers in the United States and the European Union have found that this ingredient is likely to cause human skin allergies, especially when used for a long time; 2. Because natural latex contains protein, this elastic bandage is easy to rot, mold, and deteriorate, and it is not easy to last for a long time. 3. This kind of elastic bandage has an odor and its chemical properties are unstable; 4. It needs to prepare emulsified oil, emulsion, etc. during production. Difficult to guarantee

Abstract

The invention provides a synthetic rubber self-adhesive elastic bandage and a production method thereof. The synthetic rubber self-adhesive elastic bandage takes a non-woven fabric substrate or a cotton fabric substrate as a bandage substrate. A layer of adhesive is respectively coated on the front surface and the back surface of the bandage substrate, and the mass formula of the adhesive is as follows: 60-80 parts of polyisoprene, 10-20 parts of styrene-butadiene rubber, 10-20 parts of polyisobutylene, 5-30 parts of modifier, 300-800 parts of solvent and 0.1-10 parts of antioxidant. The synthetic rubber self-adhesive elastic bandage synthesizes the adhesive through the chemical formula, thereby replacing natural latex and leading the produced synthetic rubber self-adhesive elastic bandage to have the advantages of low allergy property, easy preservation and simple preparation process.

Description

technical field [0001] The present invention relates to a self-adhesive elastic bandage and its production method, and in particular to a synthetic adhesive self-adhesive elastic bandage and its production method. Background technique [0002] Self-adhesive elastic bandage is an elastic bandage with self-adhesive properties and good air permeability. It is very suitable for wrapping and wrapping various parts of the human body, and it is very convenient to fix and disassemble. Therefore, it is used in medical bandaging, industrial operation protection, field work, and sports protection. Widely used in various industries. For example, medical wound dressing and orthopedic dressing; in the electronics industry, a large number of manual operations are performed by wrapping self-adhesive elastic bandages to protect fingers and so on. [0003] At present, a typical natural latex self-adhesive elastic bandage in the prior art uses natural latex as an adhesive, and the adhesive is...
