Synthesis and Curing kinetics of UV-curable Waterborne Bisphenol-S Epoxy Acrylate/Polyurethane-Acrylate Coating
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 ℃,peak temperature Tp is 71.58 ℃,the finished temperature Tf is 89.15 ℃.The curing reaction can be described by two-parameter autocatalytic (S)est(a)k-Berggren (S-B) model.This coating has a better UV-curing property.The dynamic mechanical analysis showed that the glass transition temperature Tg of coating film is 52.70 ℃.
