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 hydrophilic self-adhesive glue suitable for cold compress self-adhesive compression bandages, a preparation method and an application. The hydrophilic self-adhesive glue comprises the following components in percentage by weight: 1%-10% of polyvinyl alcohol, 1%-10% of polyethylene glycol, 0%-10% of polyvinylpyrrolidone, 20%-30% of natural latex or polyisoprene latex, 3%-10% of liquid paraffin, 2%-5% of polyacrylate emulsion, 50%-70% of water and the balance other components, wherein the percentage by weight of the natural latex or the polyisoprene latex is calculated according to dry glue. According to the hydrophilic self-adhesive glue suitable for the cold compress self-adhesive elastic bandages, the natural latex or the polyisoprene latex is compounded with PVA, PVP, PEG and the like, so that the hydrophilic self-adhesive glue can still achieve enough adhesive force under the wetting condition, and the peel strength is larger than or equal to 0.03KN / m.

Description

technical field [0001] The invention belongs to the technical field of self-adhesives, in particular to a hydrophilic self-adhesive suitable for cold compress self-adhesive compression bandages. Background technique [0002] The traditional cold compress bandage is composed of elastic cotton base material and cold compress liquid, and the compression effect is poor. 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 compresses, and the adhesive force decreases significantly after wetting. Contents of the invention [0003] The invention provides a hydrophilic self-adhesive adhesive suitable for cold compress self-adhesive compression bandages with good hydrophilicity and strong adhesive force after wetting. The invention also provides a preparation method for the above-mentioned hydrophi...
