摘要:

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。

Abstract:

t is very meaningful work to introduce isocyanate terminated prepolymer into solid propellant. Concerning improving mechanical properies of solid propellant, theoretical analysis is explained and experimental datas are reported.The research preliminarily shows that isocyanate terminated propolymer enhances mechanical properties of solid propellant improves its elongation rate at low temperature obviously and modificates its other performances somehow.
