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 between ADN (ammonium dinitramide) and propellant adhesives, hardeners, plasticizers and high-energy fillers were investigated by high pressure differential scanning calorimetry (PDSC). The results showed that the decomposition temperature of binary mixture of ADN and PEG, TDI and HDI was 16.3 ~ 26.9 ℃ lower than that of ADN. The interaction between ADN and NG-BTTN, TEGDN, Bu-NENA and PEG HMX binary mixture decomposition temperature slightly higher than the ADN decomposition peak temperature of 0.5 ~ 7.5 ℃, the decomposition temperature corresponding to the mixture of NG-BTTN, TEGDN, Bu-NENA and HMX decomposition temperature lower 5.9 ~ 14.4 ℃, the mixed system of mutual The difference between the decomposition temperatures of ADN and GAP, PBT, PET, IPDI, N-100, NG, TMETN, BDNPA-F and Al binary mixtures is less than 2 ℃ with the single component decomposition temperature. .
