摘　　要：以羟丙基硅油MOK-7800、异氟尔酮二异氰酸酯IPDI和甲基丙烯酸羟丙酯HPMA为原料,合成了一种紫外光固化树脂HPSACR。通过红外光谱(FT-IR)跟踪反应进程,通过动态热机械分析仪(DMA)、拉伸试验机和热重分析仪(TGA)研究HPSACR与三羟甲基丙烷三丙烯酸酯(TMPTA)以不同比例共混紫外光固化样品的热机械性能、力学性能和热稳定性。最终确定,HPSACR与TMPTA以10∶7.5比例共混所得紫外光固化样品较优,储能模量在-40℃,25℃和40℃分别为668.3MPa,542.5MPa和434.6MPa,玻璃化转变温度为91.65℃;常温弹性模量为677.85MPa,断裂伸长率为95.295%;氮气气氛下初始降解温度T5%和T10%分别为292.06℃和301.90℃,残炭率为2.082%。A UV-curing resin HPSACR was synthesized with hydroxypropyl silicone oil MOK-7800, isophorone diisocyanate IPDI and hydrox-ypropyl methacrylate HPMA as raw materials. The reaction process was tracked with infrared spectroscopy（FT-IR）. The thermal mechanical properties, mechanical properties and thermal stability of the UV-curing HPSACR and trimethylolpropane triacrylate（TMPTA）blends with different mixing ratios was studied through dynamic thermal mechanical analyzer（DMA）, cupping machine and thermogravimetric analyzer（TGA）. Finally, it was confirmed that the UV-curing samples was superior when the HPSACR and TMPTA were mixed with a ratio of 10：7.5, the storage modulus at-40 ℃,25℃ and 40℃ were 668.3 MPa, 542.5 MPa and 434.6 MPa respectively, and the glass transition temperature was 91.65 ℃. The elastic modulus was677.85 MPa at normal temperature, and the elongation at break was 95.295%. The initial degradation temperature in nitrogen atmosphere T5%and T10%were 292.06℃ and 301.90℃ respectively, and the char yield was 2.082%.
