Problems solved by technology

For example, the Chinese patent No. 00117267.0 reports a kind of natural latex medical self-adhesive bandage in the invention patent. Due to the use of too much surface active substances such as emulsified oil and emulsion, the product is enriched on the surface of the film after drying, causing the product The self-adhesive performance is reduced, and it cannot meet the protection needs of strong self-adhesive performance, such as sports and animals.
Patent No. 200410064987.X discloses a synthetic adhesive self-adhesive elastic bandage. Although this product has improved performance compared to natural latex products, the product sometimes has an oily smell due to the use of solvent gasoline. There are deficiencies that are difficult to eliminate in terms of safety performance
[0003] In addition, due to the characteristics of the adhesive used, the production efficiency of the above-mentioned technology is low in practical application, the process is more complicated, and the product quality and stability are difficult to guarantee.

Abstract

The invention relates to a self-adhesive flexible bandage, which is formed by flexible fabric and adhesive adhered at two surfaces of fabric. Wherein, the adhesive comprises following components that natural latex at 100 deals, bodying agent at 0.5-5 deals while the best is 1-4 deals as 2 deals. The invention has better penetration, without adhesive feeling, and its adhesive property is improved.

Description

technical field [0001] The invention relates to a bandage, in particular to a self-adhesive elastic bandage. Background technique [0002] The self-adhesive elastic bandages in the prior art are generally made of high-molecular polymer elastomers such as natural rubber or synthetic natural rubber into relatively uniform low-molecular dispersions by means of solvents or emulsions, and are applied by spraying, scraping or dipping. On the surface of the elastic substrate, the viscoelasticity of the rubber itself is used to make an elastic bandage product with self-adhesive properties. For example, the Chinese patent No. 00117267.0 reports a kind of natural latex medical self-adhesive bandage in the invention patent. Due to the use of too much surface active substances such as emulsified oil and emulsion, the product is enriched on the surface of the film after drying, causing the product The self-adhesive performance declines, which cannot meet the protection needs of sports a...
