| titleOfInvention | UV-cured water-based hyperbranched polyurethane acrylate and preparation method thereof |
| abstract | The invention discloses UV-cured water-based hyperbranched polyurethane acrylate and a preparation method thereof, wherein the preparation method comprises the following steps: mixing diisocyanate and dihydric alcohol in an aprotic solvent, reacting to obtain an intermediate, and adding a monoamino polyhydroxy monomer to obtain a nucleus; diisocyanate and monoamino polyhydroxy monomer react in an aprotic solvent to obtain AB2 monomer, and AB2 monomer and 'nucleus' are mixed and react to obtain hyperbranched polyurethane; adding maleic anhydride into hyperbranched polyurethane for end group modification, reacting hydroxyl-containing acrylate with diisocyanate to generate a monomer, and adding a catalyst; then mixing the products of the two reactions, and adding a catalyst; and finally, adding a neutralizing agent, reacting, separating and drying to obtain white powdery UV photocuring hyperbranched waterborne polyurethane acrylate. The UV photocuring hyperbranched waterborne polyurethane acrylate can be dispersed in a water phase, and can be rapidly cured after UV illumination. |
