Na2·cis-BNT和G2·trans-BNT与几种含能材料相互作用的热分析
Thermal Analysis of Interaction of Na2·cis-BNT and G2·trans-BNT with Some Energetic Components
摘要
Abstract
The compatibility of sodium and guanidinium salts of bis(3-(5-nitro-1,2,4-triazole))(Na2·cis-BNT, G2·trans-BNT) with cyclotrimethylenetrinitramine(RDX), cyclotetramethyle-netetranitroamine(HMX) and 3,3-diazidomethyl oxetane-glycidyl azide polymer(BAMO-GAP),and the thermal behaviors of the mixture system were investigated by differential scanning calorimetry (DSC) and thermogravimetry-derivative thermogravimetry (TG-DTG).The effect of sample preparation methods (grinding method or solvent method) on the compatibility of mixed system was preliminarily explored.The results show that there are some differences in compatibility results of the mixed system obtained by dry method and wet method for Na2·cis-BNT and G2·trans-BNT, When the binary systems are prepared by grinding method, the Na2·cis-BNT/RDX system is compatible, Na2·cis-BNT/HMX system is slightly sensitive, which is suitable for short-term use, while G2·trans-BNT/RDX system is sensitive and G2·trans-BNT/HMX system is incompatible.When the binary systems are prepared by solvent method, the mixtures of Na2·cis-BNT with RDX, HMX, BAMO-GAP and G2·trans-BNT with BAMO-GAP are compatible, but the mixtures of G2·trans-BNT/RDX and G2·trans-BNT/HMX are sensitive, which are not suitable for use.The sample preparation methods have an influence on the compatibilities of HMX based mixtures for its heterogeneous thermal decomposition process.Therefore, when the compatibility is determined by DSC, the mixing method of the sample prearation needs to be clearly explained and the final judgment shall be combined with other methods.关键词
