【摘要】 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℃。更多还原

【Abstract】 On the basis of the study of thermal behavior of ammonium dinitramide(ADN) and the interaction between ADN and NC,the influences of stabilizers,such as N-methyl-p-nitroaniline(MNA),1,3-dimethyl-1,3-diphenylurea(C2),2-nitrodianiline(2-NDPA),hexamethylenetetramine(HMT) and its complex MNA/C2,MNA/2-NDPA and MNA/HMT,on the nascent interactions between ADN and NC were investigated by using the method of DSC.The results show that the interaction between ADN and NC can be decreased to a certain extent by mixing MNA and C2,and the nascent interaction between ADN and NC can be inhibited obviously by mixing the complex of MNA/C2,MNA/2-NDPA and MNA/HMT.Comparing the binary system of ADN/NC,the value of △Tp,which is the DSC exothermic peak temperature different between ADN/stabilizer and NC,can be decreased from 19.2℃ to 11.9℃ by using the mixtures of stabilizers.更多还原
