在研究二硝酰胺铵(ADN)的热行为特性及其与硝化纤维素(NC)相互作用的基础上,利用差示扫描量热法(DSC)研究了稳定剂N-甲基对硝基苯胺(MNA)、二号中定剂(C2)、2-硝基二苯胺(2-NDPA)、六次甲基四胺(HMT)及其复配体系(MNA/C2、MNA/2-NDPA、MNA/HMT)对ADN与NC之间初期相互作用的影响。结果表明,稳定剂MNA和C2可使ADN与NC之间的相互作用得到一定程度的减弱,MNA与C2、2-NDPA和HMT的复配协同作用对ADN与NC之间的初期相互作用产生了较为明显的抑制作用,与NC/ADN二元混合体系相比,NC/(ADN/稳定剂)体系的DSC峰温提前量可由19.2℃缩减至11.9℃。
Based on the study of the thermal behavior of ammonium dinitramide (ADN) and its interaction with nitrocellulose (NC), the effects of stabilizer N-methyl-p-nitroaniline (MNA), No. 2 (C2), 2-NDPA, HMT and its complex system (MNA / C2, MNA / 2-NDPA, MNA / HMT) on the initial interaction between ADN and NC. The results showed that the interaction between ADN and NC was attenuated to a certain degree by the stabilizers MNA and C2. The synergistic effect of MNA with C2,2-NDPA and HMT resulted in the initial interaction between ADN and NC Compared with the NC / ADN binary system, the DSC peak temperature advance of NC / (ADN / stabilizer) system can be reduced from 19.2 ℃ to 11.9 ℃.
