摘要:
A three-dimensional printing photocurable composition includes from 20 wt% to 70 wt% of an urethane acrylate component, from 20 wt% to 60 wt% of a multifunctional epoxide component, from 1 wt% to 15 wt% of a monomer component, and from 1 wt% to 8 wt% of a photoinitiator component, based on the total weight of the composition. The urethane acrylate component includes the capping reaction product of an acrylate and an isocyanate terminated prepolymer and the isocyanate-terminated prepolymer is the reaction product of a polyisocyanate and at least one polyol having a molecular weight of at least 3000 g/mol. The multifunctional epoxide component includes one or more multifunctional epoxides. The monomer component includes at least one of a multifunctional acrylate monomer and a multifunctional vinyl ether monomer.
摘要(中):
三维印刷光固化性组合物包含20重量%至70重量%的氨基甲酸酯丙烯酸酯组分,20重量%至60重量%的多官能环氧化物组分,1重量%至15重量%的单体组分,以及 1重量%至8重量%的光引发剂组分,基于组合物的总重量。 氨基甲酸酯丙烯酸酯组分包括丙烯酸酯和异氰酸酯封端的预聚物的封端反应产物,异氰酸酯封端的预聚物是多异氰酸酯与至少一种分子量至少为3000g / mol的多元醇的反应产物。 多官能环氧化物组分包括一种或多种多官能环氧化物。 单体组分包括多官能丙烯酸酯单体和多官能乙烯基醚单体中的至少一种。
