合成了一种新型含能固化剂--叠氮缩水甘油醚接枝四官能度异氰酸酯（N100-g-GAP），并用红外光谱（FT-IR）和凝胶渗透色谱（GPC）对其进行了表征。以N 100-g-GAP和端炔基聚氧乙烯-四氢呋喃（ATPET）为原料，制备了聚三唑聚氧乙烯-四氢呋喃（PTPET）弹性体。通过TGA、DMA、FTIR和力学性能测试对PTPET弹性体进行了表征。上述分析表明，使用N100-g-GAP作为固化剂的PTPET弹性体具有用于推进剂的潜力。复合推进剂的整体配方试验表明，该固化体系能有效地提高推进剂的机械强度，显著改善RDX和AP颗粒与粘结剂基体之间的界面相互作用。
A new energetic curing reagent, Glycidyl azide polymer grafted tetrafunctional isocyanate (N100-g-GAP) was synthesized and characterized by FT-IR and GPC approaches. Polytriazole polyethylene oxide-tetrahydrofuran (PTPET) elastomer was prepared by N100-g-GAP and alkynyl terminated polyethylene oxide-tetrahydrofuran (ATPET). The resulting PTPET elastomer was fully characterized by TGA, DMA, FTIR and mechanical test. The above analysis indicates that PTPET elastomers using N100-g-GAP as curing reagent have the potential for use in propellants. The overall formulation test of the composite propellants shows that this curing system can effectively enhance mechanical strength and bring a significant improvement in the interface interaction between the RDX & AP particles and binder matrix.
