摘　　要：用高压差示扫描量热法（ PDSC）,研究了ADN（二硝酰胺铵）与推进剂的粘合剂、固化剂、增塑剂和高能填料的相互作用及相容性。结果表明,ADN与PEG、TDI和HDI二元混合物的分解温度比ADN的分解峰温低16.3~26.9℃,混合体系相互作用危险,相容性差；ADN与NG-BTTN、TEGDN、Bu-NENA和HMX二元混合物的分解温度略高于ADN的分解峰温0.5~7.5℃,对应混合物的分解温度比NG-BTTN、TEGDN、Bu-NENA和HMX的分解温度低5.9~14.4℃,混合体系的相互作用较为敏感；ADN与GAP、PBT、PET、IPDI、N-100、NG、TMETN、BDNPA-F和Al二元混合物的分解温度与各单组分分解温度差小于2℃,上述组分相容。The interaction and compatibility of ADN with various main compositions of propellant, including binders, curing a-gents, plasticizers and energetic fillers, were investigated by means of PDSC.Results show that Tp（decomposition temperature） of ADN-PEG,-TDI and -HDI dual mixing system is 16.3~26.9℃ lower than Tp of ADN.The interactions between them are dangerous and ADN is incompatible with PEG, TDI and HDI;Tp of ADN-NG/BTTN,-TEGDN,-Bu-NENA and-HMX dual mixing system is 0.5~7.5 ℃ higher than Tp of ADN and 5.9~14.4℃ lower than those of corresponding compositions（NG/BTTN, TEGDN, Bu-NE-NA and HMX）, thus the interactions between them are sensitive;ΔTp（difference of decomposition temperature） of ADN-GAP, -PBT,-PET,-IPDI,-N-100,-NG,-TMETN,-BDNPA-F and -Al dual mixing system with the corresponding compositions is less than 2 ℃, and ADN is found to be compatible with compositions mentioned above.
