description | The invention discloses an activated carbon polyurethane foam dressing and a preparation method thereof. The activated carbon polyurethane foam dressing comprises a foam matrix grafted with activated carbon particles and a waterproof and breathable backing layer. The activated carbon particles are subjected to water-phase premixing protection and then are subjected to simultaneous mixing foaming with a polyurethane prepolymer and foaming aid mixed solution to be grafted to the polyurethane foam matrix, the activated carbon particles and the foam matrix are firmly combined without falling scraps, and the activated carbon particles and the foam matrix are in a weak surface grafting state; the polyurethane prepolymer and the foam matrix thereof basically do not enter through holes in the activated carbon particles, the adsorption performance of the activated carbon particles is well preserved, the biotoxicity residue is low, and the functional dressing prepared by the method can be widely applied to treatment of |
