摘要
用差示扫描(DSC)和热重分析(TG)研究了斯蒂芬酸铅(LS)/硝化棉(NC)/双铅2(SQ-2)推进剂热稳定性。用热力计算方法分析了四种推进剂(高氯酸铵(AP)/端羟基聚丁二烯(HTPB),AP/NC,LS/NC和LS/SQ-2)的能量特性。研究了配比为55,64,73三种LS/NC推进剂和配比为46,55,64,73四种LS/SQ-2推进剂的热分解特性。结果表明:添加NC或SQ-2能降低LS的热稳定性,提高推进剂的能量,其中NC的效果更显著,认为LS和NC可选作微型发动机用推进剂的组分。
Thermal stabilities of lead styphnate(LS) / nitrocellulose(NC)/ dibasic lead stearate(SQ-2) were studied by Different Scanning Calorimetry(DSC) and Thermogravimetry(TG).The energetic properties of four propellants(ammonium perchlorate(AP) / hydroxy-terminated polybutadiene(HTPB),AP/NC,LS/ NC and LS /SQ-2) were analyzed with thermodynamic calculation method.Thermal decomposition characteristics of three LS/NC propellants with ratio of LS to NC as 55,64 and 73 and four LS/SQ-2 propellants with ratio of LS to SQ-2 as 46,55,64 and 73 were researched.Results show that the thermostability of LS decreases by adding NC or SQ-2,and its energy enhances,in which the effect of NC is more obvious,considering that LS and NC can be chosen as the components of propellant used in micro solid rocket motor.
