제목 Synthesis and Curing kinetics of Urethane Acrylate for DLP-SLA type 3D Printer
초록 UV curable coating materials has been widely used various industries such as automotive, coil coating, exterior wood printing and adhesives owing to environmental advantages. In this research, we synthesized eco-friendly urethane acrylate (UA) using isosorbide and other acrylate monomers to enhance film properties and their curing kinetics. Especially we used two kinds of isocyanate of 4,4′-Methylenebis(cyclohexyl isocyanate (H12MDI) and Isophorone diisocyanate (IPDI) which are non-yellowing type chemicals. And another chemical of ACMO was used for adhesion strength. And urethane acrylate were polymerized isosorbide methacrylate and poly(tetramethylene ether) glycol (PTMG). It were found that the molecular weight average (Mw) for PUA has a range of 15,000~20,000 g/mol and PDI of 2.1~2.5 via Gel permeation chromatography (GPC). Finally we observed pencil hardness and their curing kinetics of isosorbide-PTMG methacrylate according to different kinds of isocyanate.
