| 摘 要： | 针对环氧/氰酸酯共固化体系,以液氧冲击敏感性试验作为判定聚合物与液氧相容性的基本手段,重点研究了聚合物的抗氧化和阻燃性能与其液氧相容性之间的关系,证实了聚合物抗氧化性能的增强和阻燃性能的改善可以有效提高其与液氧的相容性.这为聚合物旨在改善与液氧相容性的改性指明了方法和途径,并由此获得两个具有良好液氧相容性的聚合物体系.

| Abstract: | Epoxy and cyanate ester co-curing systems were selected as the main system of the study. Their compatibility with liquid oxygen was characterized by the liquid oxygen impact test. Thermal analysis and oxygen index were used to represent the polymers' anti-oxidation and flame-retardant properties. The inherent relationship between anti-oxidation and flame-retardant properties of polymers and their compatibility with liquid oxygen were studied thoroughly. The conclusion was drawn that polymers with better anti-oxidation and flame-retardant properties had better compatibility with liquid oxygen. Two co-curing system with desirable compatibility with liquid oxygen were established by modifying the polymers in the two ways respectively. |
