Abstract

The invention discloses a silver-bearing hydrocolloid dressing, the surface of a base material (1) thereof is covered with a functional layer, the functional layer is a hydrophilic colloid layer (2), one side of the hydrophilic colloid layer (2) covers the base material (1), the other side thereof is covered with a disjuncting layer (3). The invention also discloses a preparation method of the silver-bearing hydrocolloid dressing. Firstly, rubber base material, glutin, mineral oil and antioxidant are mixed, blended evenly and sufficiently in a Banbury mixer and added with sodium carboxymethyl cellulose, tackifier and antibacterium silver ion solution in turn until being evenly mixed to form a mixture, the mixing weight ratio of sodium carboxymethyl cellulose, rubber base material, mineral oil, tackifier, glutin, antioxidant and antibacterium silver ion solution is 20-50:10-40:10-20:10-20:5-20:1-10:1-10; secondly, the evenly mixed mixture is coated evenly on the base material (1) to form the hydrophilic colloid layer (2), meanwhile the hydrophilic colloid layer is covered with the disjuncting layer.

Description

technical field

[0001] The invention relates to a silver-containing hydrocolloid dressing and a preparation method thereof. Background technique

[0002] Current dressings such as gauze have poor liquid absorption, are not waterproof, and are prone to infection. They may stick to the wound when they are removed, so infection is easy to occur. In addition, Chinese patent ZL 200520071622.X describes a polymer antibacterial dressing composed of hollow acetate fiber nonwoven fabric and lipid glue layer. It uses hollow acetate fiber nonwoven fabric as the base material, and the base material is coated with grease The glue layer is composed of liquid silicone rubber, sodium carboxymethyl cellulose, solid nano-silver ion antibacterial agent, medical vaseline, liquid paraffin, and citric acid. However, this dressing has the disadvantages of poor isolation of the non-woven fabric base material, not waterproof, unable to block bacteria, and opaque. And with the continuous improvemen...
