Synthesis of solvent-free urethane-acrylate IPN type adhesives with soft and rigid dual polymer networks |
| 초록 |
Currently, there are increasing interests in eco-friendly adhesives such as zero VOCs and solvent-free adhesives in various industries. Among them, solvent-free adhesives of a single composition using acrylate monomers suffered from many difficulties. In this study, solvent-free urethane-acrylate IPNs adhesives with unique structure in which urethane polymer networks with soft properties and acrylate polymer networks with hard properties was entangled were studied. First, PPG-based urethane prepolymers were polymerized using acrylate monomers as the solvent, and final solvent-free urethane-acrylate IPNs adhesives were prepared by photo-polymerizing the acrylate monomer. Polymerizations of urethane and acrylate polymer were confirmed by 1H-NMR and FT-IR methods, and the properties of OH-terminated urethane prepolymers were confirmed using GPC, viscometer and potentiometer. Through the possibilities of application in real life as paint binders and adhesives were confirmed. |
