Two types of bonding agents were synthesized based on polyetheramines (PEAs), which aim to increase the strain of AP/CL-20/GAP formulation. The PEAs, terminated with cyano (CTPEA) and Schiff base (SBPEA) groups, were applied in the AP/CL-20/GAP formulation, respectively. The results showed that the bonding agents TCN-403 (CTPEA) and TBA-403 (SBPEA), which were prepared from trifunctional PEA named as T-403, could significantly increase the maximum elongation ratio of the formulation. The differences between the TCN-403 and TBA-403 were analyzed by DMA of the formulations, SEM of the coated fillers, and in-situ tensile test, indicating that the Schiff base bonding agents can effectively inhibit the dewetting of the binder from the solid particles in the formulations.

聚醚胺基粘合剂的合成及其对 AP/CL-20/GAP 配方机械性能的影响

基于聚醚胺 (PEA) 合成了两种类型的粘合剂，旨在增加 AP/CL-20/GAP 配方的应变。以氰基 (CTPEA) 和席夫碱 (SBPEA) 基团封端的 PEA 分别应用于 AP/CL-20/GAP 配方中。结果表明，以T-403三官能团PEA为原料制备的粘合剂TCN-403（CTPEA）和TBA-403（SBPEA）能显着提高配方的最大伸长率。通过配方的DMA、包覆填料的SEM和原位拉伸试验分析了TCN-403和TBA-403之间的差异，表明席夫碱粘合剂可以有效地抑制粘合剂从固体中的去湿配方中的颗粒。
