Abstract
In this study, waterborne polyurethane acrylate were synthesized with polyester polyol, 4,4-dicyclohexylmethane diisocyanate ($H_{12}MDI$), dimethylol propionic acid (DMPA), acrylate monomer to improve the properties and peel strength. In addition, the properties of the synthesized waterborne polyurethane acylate was evaluated through FT-IR, particle size analysis, UTM, peel strength. As the acrylic acid content increased, particle size increased. In the results of mechanical properties, when the acrylic acid contents increased, tensile strength was increased but elongation was decreased. All peel strength was improved as the acrylic acid contents of WPUA and acrylate ratio of PU/acrylate increased. Optimum peel strength obtained when acrylic acid was 0.5 wt%.
