| 中文摘要 | A series of waterborne UV-curable acrylated polyurethanes were synthesized with the objective to improve their mechanical properties and resistance to water. Toluene 2,4-diisocyanate (TDI), polyethylene glycol (PEG), 2,2-dimethylolpropionic acid (DMPA), and beta -hydroxyethyl methacrylate (HEMA) were used as the raw materials. H-NMR analysis shows that less than 15% of the isocyanate groups participated in side reactions during the synthesis reaction. Dynamic light scattering measurements show that the particle size in the dispersions decreased with increasing DMPA content in the polymers. The resistance to water of the cured coatings is better than that of uncured coatings. Both the glass transition temperature and the hardness of the cured coatings increased with increasing acrylate group content in the polymers. |
