| titleOfInvention | Urethane acrylate compound comprising carbodiimide modified methylene diphenyl diisocyanate, toluene diisocyanate and trimethylolpropane terpolymer structure and the photo curable composition with high strength, high thermal resistance and high elongation for 3D printing using thereof |
| abstract | The present invention relates to a urethane acrylate compound having a terpolymer structure of carbodiimide-modified methylenediphenyl diisocyanate, toluene diisocyanate and trimethylolpropane, and a high strength, high heat resistance and high elongation 3D photocurable composition using the same, Specifically, methylene diphenyl diisocyanate, an aromatic bifunctional isocyanate compound, is carbodiimidized in the presence of a carbodiimidization catalyst to prepare carbodiimide-modified methylenediphenyl diisocyanate, and then the carbodiimide-modified methylene diisocyanate is prepared. Diphenyl diisocyanate, toluene diisocyanate and trimethylolpropane are reacted to make a terpolymer urethane reaction of the trimethylolpropane polyol and the carbodiimide-modified methylenediphenyl diisocyanate and toluene diisocyanate, and the carbodii of the terpolymer Radical curing is possible by adding an acrylate or methacrylate having a hydroxyl group to the terminal residual isocyanate group of each of the mid-modified methylenediphenyl diisocyanate and toluene diisocyanate. Urethane acrylate compound having a terpolymer structure of carbodiimide-modified methylenediphenyldiisocyanate, toluene diisocyanate and trimethylolpropane applicable to DLP-based 3D printing and high strength, high heat resistance and high elongation 3D photocuring using the same It's about the composition. |
