摘　　要：以异佛尔酮二异氰酸酯(IPDI)、甲基丙烯酸羟乙酯(HEMA)、聚四氢呋喃醚二醇(PTMEG)为原料合成高性能聚氨酯,并向聚氨酯中添加光引发剂、三羟甲基丙烷三丙烯酸酯(TMPTA)、1,6-己二醇二丙烯酸酯(HDDA)得到3D打印光固化聚氨酯材料配方。利用SLA-3D打印机打印出制品并测试其力学性能。结果表明,光固化聚氨酯具有高弹性模量、高断裂伸长率。Polyurethane with high performance was synthesized by using isophorone diisocyanate(IPDI),2-hydroxyethyl methacrylate(HEMA)and polytetramethylene ether glycol(PTMEG)as raw materials.The formula of 3Dprinting UV curing material was obtained by adding photoinitiators,trimethylolpropane(TMPTA),1,6-Hexanediol diacrylate(HDDA)into polyurethane.The products were printed by SLA-3Dprinter,and the mechanical properties of the products were tested.The results show that UV curing polyurethane has high elastic modulus and high elongation at break.
