Abstract

The invention discloses an anti-sticking dressing and a manufacturing method thereof. The anti-sticking dressing includes a water-based foaming layer and a polyurethane membrane formed thereon, and the bottom of the water-based foaming layer is used for attaching to a wound of skin. A main agent is formed by mixing hardener hexamethylene diisocyanate, polyethylene glycol, polypropylene glycol, 2,2-Bis(hydroxymethyl)propionic acid, ethylenediamine and 1,4-butanediol, when 1,4-butanediol is added, a functional additive is added to form a prepolymer; and the prepolymer is processed into a mechanical foaming body by utilizing a mechanical foaming machine, and centrifugal paper is coated with the foaming body to form the water-based foaming layer.

Description

technical field [0001] The invention relates to an anti-adhesion dressing, in particular to an anti-adhesion dressing prepared by a mechanical foaming machine and a manufacturing method thereof. Background technique [0002] As we all know, in the traditional high-absorbent foam dressing and its manufacturing method, the traditional technology does not use water-based polyurethane, nor does it add functional additives. In addition, in terms of adding methods, the traditional technology uses physical mixing. These have resulted in poor moisturizing effect and no antibacterial function of traditional high-absorption foam dressings, so it is urgent to improve them. In addition, conventional technology uses non-woven fabrics and does not apply dot glue on the polyurethane film. Contents of the invention [0003] The present invention aims to solve the above-mentioned problems of poor moisturizing effect, no antibacterial function, and difficult absorption of wound tissue flui...
