Problems solved by technology

[0002] The traditional cold compress bandage is composed of elastic cotton base material and cold compress liquid, the compression effect is poor, and the outer layer needs to be fixed with PP non-woven self-adhesive elastic bandage to strengthen the compression effect
However, the adhesive and substrate of ordinary self-adhesive bandages are not hydrophilic, so they cannot absorb cold compress fluid, and the adhesive force decreases significantly after wetting

Abstract

The invention discloses a hydrophilic self-adhesive suitable for cold compressing self-adhesive compression bandages and a preparation method and application, wherein the weight percentage of the hydrophilic self-adhesive comprises: polyvinyl alcohol: 1%-10%, polyvinyl alcohol Ethylene Glycol: 1%-10%, Polyvinylpyrrolidone: 0%-10%, Natural Latex or Polyisoprene Latex: 20%-30%, Liquid Paraffin: 3%-10%, Polyacrylate Emulsion: 2%-5%, water: 50%-70%, other components: balance; the weight percentage of the natural latex or polyisoprene latex is calculated as dry rubber. The patent of the present invention provides a hydrophilic self-adhesive adhesive suitable for cold compressing self-adhesive elastic bandages, using natural latex or polyisoprene latex and PVA, PVP, PEG, etc. Sufficient adhesive force can be achieved, and the peel strength is greater than or equal to 0.03KN / m.

Description

technical field [0001] The invention belongs to the technical field of self-adhesive adhesives, in particular to a hydrophilic self-adhesive adhesive suitable for cold compressing self-adhesive compression bandages. Background technique [0002] The traditional cold compress bandage system is composed of elastic cotton base material and cold compress liquid, which has poor compression effect. The outer layer needs to be fixed with PP non-woven self-adhesive elastic bandage to strengthen the compression effect. However, the adhesive and substrate of ordinary self-adhesive bandages do not have hydrophilic properties, so they cannot absorb cold compresses, and the adhesive force decreases significantly after wetting. SUMMARY OF THE INVENTION [0003] The invention provides a hydrophilic self-adhesive adhesive with good hydrophilicity and strong adhesion after wetting, which is suitable for cold compressing self-adhesive compression bandages. The present invention also provid...
