Problems solved by technology

At present, the adhesives used in self-adhesive elastic bandages at home and abroad mainly use natural latex or its modified products. Due to the presence of protein in natural latex, it is easy to cause human skin allergies, and long-term storage will cause corruption, mold, and deterioration. Therefore, Natural rubber latex or its modified products are gradually replaced by artificially synthesized adhesives. In the prior art, adhesives for self-adhesive elastic bandages have the disadvantages of being sticky to the hand, greasy to the touch, and too strong to be easily torn apart.

Abstract

The invention discloses a medical self-adhesive elastic bandage preparation method. The method includes steps: (1) mixing methacrylic anhydride, methyl methacrylate, methyl acrylate, deionized water and lauryl amine, heating to 75-80 DEG C, and continuously stirring for 60-70min to obtain mixed emulsion; (2) slowly adding a modifying agent into the mixed emulsion obtained in the step (1), heatingthe mixed liquid to 86-90 DEG C, continuously stirring for 300-350min, cooling to the room temperature, and filtering through a 150-mesh filter screen to obtain an adhesive; (3) adding a stabilizing agent into the adhesive obtained in the step (2), well stirring, and coating front and back faces of an elastic bandage with the prepared adhesive to obtain a medical self-adhesive elastic bandage. Themedical self-adhesive elastic bandage prepared according to the method has advantages that the adhesive is nonsticky to skin and free of greasiness, wound pulling in tearing of the bandage is avoided, and excellent breathability is realized.

Description

technical field [0001] The invention belongs to the technical field of medical bandage preparation, and in particular relates to a preparation method of medical self-adhesive elastic bandage. Background technique [0002] Bandages are widely used in real life, and different injuries use different bandages. Self-adhesive elastic bandages are widely used in various industries such as medical dressing, industrial operation protection, field operation, and sports protection. This kind of self-adhesive bandage is sprayed with a layer of adhesive on the front and back of traditional medical bandages. The self-adhesiveness between them greatly facilitates bandaging and fixing, increases air permeability, and also reduces the skin pain after tearing off. At present, the adhesives used in self-adhesive elastic bandages at home and abroad mainly use natural latex or its modified products. Due to the presence of protein in natural latex, it is easy to cause human skin allergies, and ...
