| titleOfInvention | Nano calcium carbonate modified waterborne polyurethane acrylate with photosensitive group and preparation method thereof |
| abstract | The invention provides a nano calcium carbonate modified waterborne polyurethane acrylate with a photosensitive group and a preparation method thereof. The preparation method comprises the following steps: (1) sequentially adding diisocyanate and a catalyst into a four-neck flask provided with a stirrer, a thermometer and a reflux condenser pipe, and continuously adding an anhydrous alcohol compound under a stirring state to react to obtain a polyurethane prepolymer; (2) sequentially adding 2, 2-dimethylolpropionic acid and nano calcium carbonate with photosensitive groups into the polyurethane prepolymer, and reacting to obtain a water-based polyurethane prepolymer; (3) adding an acrylate compound containing hydroxyl and unsaturated double bonds and a phenol polymerization inhibitor into the waterborne polyurethane prepolymer, and reacting to obtain a waterborne polyurethane acrylate prepolymer; (4) and adding triethylamine into the aqueous polyurethane acrylate prepolymer for neutralization and salt formation reaction, and continuously adding deionized water for emulsification to obtain the photosensitive group-containing nano calcium carbonate modified aqueous polyurethane acrylate. |
