The invention discloses paper diapers adopting water-absorbing macromolecule materials and a preparation method of the paper diapers adopting water-absorbing macromolecule materials, and belongs to the technical field of paper diapers. The paper diapers adopting water-absorbing macromolecule materials comprise a surface coating layer, an absorption sandwich layer and a backing cloth, wherein the surface coating layer adopts skin-friendly non-woven fabrics, the absorption sandwich layer adopts water-absorbing macromolecule materials, the backing cloth adopts PE films, the water-absorbing macromolecule materials consist of the following components of licorice roots, glabrous greenbrier rhizomes, honeysuckle flowers, gardenia stenophylla Merr, milk protein fibers, acrylic acid, acetyl chitin,polyacrylamide, methyl methacrylate, vinyl acetate, a cross-linking agent and an initiating agent. According to the paper diapers adopting water-absorbing macromolecule materials disclosed by the invention, the absorbing capacity and the absorbing rate of infant urine by the paper diapers can be effectively increased, the situation of urine leakage produced due to large urine discharging quantityof infants in the use process of the paper diapers can be avoided, besides, the bacterium restraining and bacterium resisting effects of the paper diapers can also be effectively improved, breeding of bacteria in the urine can be restrained, and the situation that bacteria bred in the urine infect infant skin can be avoided.
