Abstract:

以纳米铝粉、纳米氧化铅和纳米三氧化二铋为原料,利用超声分散复合法制备了超级铝热剂Al/PbO和Al/Bi2O3。采用X射线粉末衍射(XRD)、扫描电镜及能谱分析(SEM-EDS)和红外光谱(FT-IR)对原料和产物的物相、组成、形貌和结构进行分析表征;利用真空安定性实验仪(VST)和差示扫描量热仪(DSC)研究了两种超级铝热剂与硝化棉(NC)、吸收药(NC+NG)、黑索今(RDX)、吉纳(DINA)和二号中定剂(C2)五种双基系推进剂主要组分的混合体系的相容性。结果表明,VST法和DSC法实验一致判断纳米超级铝热剂与双基系推进剂主要组分NC,NC+NG和DINA有较好的相容性;而Al/PbO和Al/Bi2O3分别与RDX和C2组成的混合物体系则有不同的分析结果,VST法判断为相容,而DSC法却认为体系敏感,分析了不同方法得出不同结论的原因。
