Paper Abstract

A novel multifunctional UV-curable waterborne polyurethane-acrylate(WPUA) was synthesized with isophorone diisocyanate(IPDI), polycaprolactone diols(PCL), dimethylol propionic acid(DMPA) and pentaerythritol triacrylate (PETA). The chain structure of the WPUA was identified by 1H NMR spectrum. After that, the nanosilica modified with KH570 was dispersed in WPUA, and the effects were studied with dispersion and cast films. It was found that the viscosity of the hybrid emulsion was increased, and the water resistance, abrasion resistance and mechanical properties were improved with the addition and increasing amount of silica, to provide the WPUA/SiO2 hybrid materials with excellent performance and more expansive prospects.
