The present invention relates to a porous water-dispersed polyurethane resin containing natural products and a method for producing the same, and aims at synthesizing an aqueous dispersion of a polyurethane / natural extract nanoparticle composite and multifunctional expression obtained from the resin. The water-dispersed polyurethane resin of the present invention has different polyols, isocyanate groups, ionic ion center content, nanoparticle content and neutralization ratio, and a continuous mixture of natural extract particles and polyurethane prepolymer It is incorporated into and dispersed in an aqueous dispersion of particles to have the properties of a three-dimensional water-dispersed polyurethane. |
