Abstract: A UV-curing resin HPSACR was synthesized with hydroxypropyl silicone oil MOK-7800, isophorone diisocyanate IPDI and hydroxypropyl 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 668.3MPa, 542.5MPa and 434.6MPa respectively, and the glass transition temperature was 91.65℃. The elastic modulus was 677.85MPa 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%.
