摘要
Abstract
Bu-NENA ( N-butyl-N-nitratoethylnitramine )/NC ( nitrocellulose ) double-base propellant was formulated with Bu-NENA as a replacement for NG ( nitroglycerin) and t he NG/NC propellant was also prepared as a control.The sensitvity, evaporation, thermal decomposition and mechanical properties of the double-base propellants were investigated.Results show that the friction sensitivity of the Bu-NEN A/NC propellant drops to 18%from 94%, and the H50 of the impact esnsitivity enhances to 27.1 cm from 8.1 cm.Thermogravimetr ic analysis of Bu-NENA/NC propellant reveals that the onset etmperature and the peak temperature of first decomposition stage reach to 144.6℃and 179.5 ℃from 120.3℃and 151.5℃, respcetively.The value of evaporation rate for Bu-NENA/NC prope llant at 80, 90,100 ℃ is lower than that of NG/NC propellant,which indicates that the volatility of the Bu-NENA/NC propell ant decreases.Bu-NENA/NC double-base propellant has better mechanical property than NG/NC propellant and the low temperature elongation at break point rises to 13.63%, whichsi 1.63 times to that of the NG/NC propellant.关键词
