摘要
研究了细AP含量、增塑剂癸二酸二异辛酯 (DOS)含量和键合剂LW1等因素对HTPB/IPDI高燃速推进剂 - 5 5℃低温力学性能的影响 ,获得了一个使用温度范围广 (- 5 5℃～ + 70℃ )、综合性能优良的丁羟高燃速推进剂配方。该推进剂除具有能量高、燃速高等特点外 ,还有优良的力学性能 ,70℃最大抗拉强度 (σm)大于 0 5MPa ,2 5℃ ,70℃最大伸长率 (εm)大于 45 % ,- 5 5℃时的伸长率大于 30 %。
The effects of the contents of fine ammonium perchlorate (AP) and plasticizer di-2-ethylhexyl sebacate (DOS) and bonding agent LW1 on mechanical properties of high burning rate HTPB/IPDI propellant at -55 °C were studied. A high burning rate HTPB propellant formulation with better comprehensive properties and used in the -55 °C ∼ + 70 °C broad temperature range was gained. Propellant formulation has better mechanical properties except for properties of high burning rate and energy. Maximum tensile strength (σm) of propellant at 70 °C is higher than 0.5 MPa. Maximum elongation (Εm) at 70 °C and 25 °C are superior to 45%. Maximum elongation (Εm) at -55 °C is higher than 30%.
