摘　　要：以双酚A型环氧树脂(E-51)、环氧丙烯酸酯(EA-612)、3-乙基-3-烯丙基甲氧基氧杂环丁烷、2-羟基-2-甲基-1-苯基丙酮(UV-1173)和三芳基锍鎓六氟锑酸盐(UV-6976)作为组分制备了一种混杂型紫外光固化材料。较佳配方为:m(E-51)∶m(EA-612)=1∶1,m(预聚物总量)∶m(3-乙基-3-烯丙基甲氧基氧杂环丁烷)=4∶1,m(UV-1173)∶m(UV-6976)=1∶1,并且复配光引发剂总量为7%。实验结果表明其紫外光固化膜的冲击强度为30kg·cm,附着力为2级,柔韧性可通过轴棒6的弯曲测试。A hybrid type UV-curing material was prepared with bisphenol A type epoxy resin（E-51）,epoxy acrylate（EA-612）,3-ethyl-3-allyloxymethyl oxetane,2-hydroxy-2-methyl-1-phenylacetone and triphenylsulphonium hexafluoroantimonate（UV-6976）as components.The optimum formulation was m（E-51）∶m（EA-612）=1∶1,m（E-51 and EA-612）∶m（3-ethyl-3-allyloxymethyl oxetane）=4∶1,m（UV-1173）∶m（UV-6976）=1∶1,and the total amount of complex photoinitiator was 7%.The experimental results showed that the impact strength of its UV-cured film was 30kg·cm,the adhesion grade was 2,and the film could go through mandrel 6of bend test in flexibility.
