摘要

In ouder to prepare the waterborne UV-curable polyurethane acrylate coatings, the anionic polyurethane acrylate emulsifier and bisphenol-S eopxy acrylate were synthesized. The curing process, kinetics and properties of waterborone UV-curable epoxy acrylate/polyurethanes acrylate coating were investigated by FTIR, DSC and DMA. The results show that the static initial curing temperature Ti is 52.36°C, peak temperature T_p is 71.58°C, the finished temperature T_f is 89.15°C. The curing reaction can be described by two-parameter autocatalytic Sestak-Berggren (S-B) model. This coating has a better UV-curing property. The dynamic mechanical analysis showed that the glass transition temperature T_g of coating film is 52.70°C.
