Preparation method of LED-curable non-isocyanate urethane acrylate

The invention discloses a preparation method of LED (light-emitting diode) curable non-isocyanate urethane acrylate, amino is respectively subjected to a ring-opening reaction and a Michael addition reaction with cyclic carbonate and unsaturated double bonds, finally, the non-isocyanate urethane acrylate is prepared, virulent isocyanate or phosgene is not used in the synthesis process, and the preparation method is green and environment-friendly. The target product shows a good drying effect, relatively high gloss and hardness and good flexibility and adhesive force under the irradiation of a 395-nanometer LED light source, and a good technical effect is achieved. 本发明公开了一种可LED固化非异氰酸酯聚氨酯丙烯酸酯的制备方法，使用氨基分别与环碳酸酯和不饱和双键进行开环反应和迈克尔加成反应，最后制备得到非异氰酸酯聚氨酯丙烯酸酯，合成过程中不使用剧毒的异氰酸酯或光气，绿色环保。目标产物在395纳米LED光源辐照下表现出良好的干燥效果，较高的光泽和硬度以及良好的柔韧性和附着力，取得了良好的技术效果。
