概述了在固体推进剂中引入端异氰酸酯预聚物以提高推进剂力学性能。研究结果初步表明，端异氰酸酯预聚物不仅对改善和提高推进剂力学性能、尤其是低温伸长率有明显作用，而且对其它性能也有一定调节效果。 The introduction of a terminal isocyanate prepolymer into a solid propellant is outlined to improve the propellant mechanical properties. The results of the preliminary studies show that the isocyanurate prepolymer not only has a significant effect on improving and enhancing the mechanical properties of the propellants, especially the low-temperature elongation, but also has other regulating effects on other properties.
