摘　　要：光固化树脂由聚氨酯丙烯酸酯(PUA),双酚A聚氧乙烯醚双甲基丙烯酸酯(BPA2),三乙二醇二甲基丙烯酸酯(TEGDMA),a,a'-二甲氧基苯偶酰缩酮(Irgacure 651),二氧化硅(SiO2)和硅烷偶联剂(Si-69) 组成。其中PUA由甲苯二异氰酸酯(TDI),聚乙二醇(PEG),甲基丙烯酸羟乙酯(HEMA)合成,是光固化树脂的重要基体原料。利用激光快速成型技术(SLA)对光固化树脂进行固化,并进行一系列性能研究,找到各组分的最佳用量配比。结果表明:当PUA的质量分数为45%,BPA2的质量分数为30%,HEMA的质量分数为25%,Irgacure 651的质量分数为4%,SiO2的质量分数为1%时,光固化树脂的综合性能最佳。The UV-curable resin consists of polyurethane acrylate (PUA), bisphenol A polyoxyethylene ether bismethacrylate (BPA2), triethylene glycol dimethyl acrylate (TEGDMA), a,a'-dimethoxyphenylacetyl condensation (Irgacure 651), silicon dioxide (SiO2) and silane coupling agent (Si-69). PUA is synthesized from toluene diisocyanate (TDI), polyethylene glycol (PEG) and hydroxyethyl methacrylate (HEMA). It is an important matrix material for light curing resin. Laser Rapid Prototyping (SLA) is used to cure light-cured resin, and the properties are studied. The optimum dosage ratio of each component is obtained. The results show that: when the mass fraction of PUA is 45%, BPA2 is 30%, HEMA is 25%, Irgacure 651 is 4%, and SiO2 is 1%, the comprehensive properties of UV curable resin are the best.
