摘要
在氰酸酯树脂(CE)中加入端羟基聚丁二烯橡胶(HTPB)以改善其韧性。利用傅里叶红外光谱(FT-IR)、热综合分析仪、原子力显微镜(AFM)等方法研究体系的反应性,测定其力学性能、耐热性等性能。实验结果表明,HTPB的加入很好地改善了CE的韧性,当HTPB含量达到25%时,体系的冲击强度提高最大,接近19 kJ/m2,并且保持了树脂良好的耐热性能。
Cyanate ester resin （CE） was modified by hydroxyl-terminated polybutadiene （HTPB）. The reactivity between the components and the properties of the system were studied using Fourier transform infrared spectroscopy （FT-IR）, DSC-TG, atomic force microscope （AFM）. It showed that the flexibility of the blends was increased without a loss in the thermal stability. When the content of HTPB is 25 G, the impact strength of the blends was close to 19 kJ/m^2.
