Problems solved by technology

[0002] In life, people are often injured and need to be bandaged. However, because of the different positions of the bandage, subcutaneous fluid and hematoma often occur due to loose bandages, which seriously affect wound healing, or hinder blood circulation due to too tight bandages. Caused many difficulties, brought great pain and economic loss to patients
In addition, the existing straps can be self-adhesive or fixed with adhesive tape, but the adhesiveness is not enough, the long hair will fall off, and it is easy to stick to hair and other substances, which will affect the adhesiveness.

Abstract

The invention discloses a medical self-adhesive elastic bandage and a preparation method thereof. The bandage comprises a medical elastic bandage, and a layer of adhesive is sprayed over the medical elastic bandage. The adhesive is composed of the following raw materials in parts by weight: 65 to 78 parts of synthesized rubber, 0.1 to 0.6 part of potassium sorbate, 1 to 4 parts of styrenated phenol, 4 to 8 parts of glycerin, 0.2 to 0.8 part of aluminum oxide, and 25 to 38 parts of water. The preparation method comprises the following steps: weighing raw materials according to the formula, grinding aluminum oxide in a ball mill, sieving to obtain aluminum oxide powder, and saving the aluminum oxide powder for later use; adding synthesized rubber, potassium sorbate, styrenated phenol, and water into a reactor, and then stirring and heating to obtain a mixture I; adding aluminum oxide powder into the mixture I after the mixture I is cooled down, stirring, then adding glycerin, keeping on stirring to obtain an adhesive, and saving the adhesive for later use; and soaking and heating a medical elastic bandage in the adhesive so as to obtain the medical self-adhesive elastic bandage. The provided bandage has the advantages of good adhesive property, good breathability, and practicality.

Description

technical field [0001] The invention relates to the field of bandages, in particular to a medical self-adhesive elastic bandage and a preparation method thereof. Background technique [0002] In life, people are often injured and need to be bandaged. However, due to the different positions of the bandage, subcutaneous fluid and hematoma often occur due to loose bandages, which seriously affect wound healing, or hinder blood circulation due to too tight bandages. Caused many difficulties, brought great misery and economic loss to the patient. In addition, the existing bandages can be self-adhesive or fixed with adhesive tape, but the adhesiveness is not enough, the long hair will fall off, and it is easy to stick to hair and other substances, which affects the adhesiveness. Therefore, it is necessary to develop a bandage with better self-adhesive properties. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the object of the present invention...
