1，1＇-二羟基-5，5＇-联四唑二羟胺盐和CMDB推进剂组分的相互作用研究

摘要

采用DSC实验、推进剂固化实验和真空安定性实验等多种手段，研究了1，1＇-二羟基-5，5＇-联四唑二羟胺盐（ HA-TO）和CMDB推进剂组分的相互作用。 DSC分析结果表明，HATO和硝化纤维素（ NC）、硝化甘油（ NG）、吉纳（ DINA）、黑索金（ RDX）、奥克托金（ HMX）和炭黑（ CB）之间存在强烈的相互作用，以及3-硝基-1，2，4-三唑-5-酮铅（ NTO-Pb）、铝（ Al）之间则无明显的相互作用。70℃条件下制备出含HATO的CMDB推进剂，DSC分析表明，受硝酸酯的作用，HATO使得CM-DB推进剂的热分解峰温提前，但在155℃以下，含HATO的CMDB推进剂无明显热分解过程。真空安定性试验结果表明，100℃条件下持续加热48 h，HATO的放气量为0．30 ml/g，含HATO的CMDB推进剂的放气量为0．39 ml/g。%The interaction of dihydroxylammonium 5,5'-bistetrazole-1,1'-diolate ( HATO) with CMDB propellant components were studied by using DSC method,curing experiment of propellant slurry and vacuum stability test.The DSC results show that there are strong interaction between HATO with nitrocellulose(NC), nitroglycerine(NG),N-nitrodihydroxyethylaminedinitrate(DINA), cyclotrimethylene-trinitramine(RDX),cyclotetramethylenete-tranitramine(HMX),and carbon black(CB),and no obvious interac-tion between HATO with lead salt of 3-nitro-1,2,4-triazole-5-one(NTO-Pb) and aluminum powder(Al).The CMDB propellant con-taining HATO was prepared by curing experiment at 70℃,and analyzed by DSC method.It was found that HATO could decrease the decomposition temperature of CMDB propellant for the interaction between HATO and nitrate ester components. Furthermore, after heating at 100 ℃ for 48 h,the volume of gas products for HATO and CMDB propellant containing HATO were determined by the vacuum stability tests to be 0.30 ml/g and 0.39 ml/g respectively.
