摘要
为了探究高能燃料在强冲击环境下的安定性,还原了燃料实际使用环境,采用爆炸冲击和电爆轰冲击,对十氢十硼酸双四乙基铵(BHN-10)在冲击效应下的安定性以及分解气相和固相产物进行了研究;在BHN-10中加入HMX,考察其对燃料分解效率的影响。结果表明,BHN-10对于单一的炸药爆轰产生的冲击作用具有较好的安定性,1.0 GPa量级的冲击波不能够促使BHN-10发生分解;BHN-10在电爆轰冲击下的安定性较低,等离子体电爆轰方法产生的冲击和热的共同作用可以促进BHN-10分解为三乙胺、腈类、碳烷烃、烯烃、炔烃等高热值的有机可燃气体;加入HMX后,气体产物的碳链长度除三乙胺外均不超过4个碳原子,长度明显变短;HMX的加入可以大幅提高BHN-10燃料的分解效率,生成更高比例的低碳链易燃气体;在N 2气氛下,其固相分解产物为C 60以及正交晶型的B 12 H 16;在空气气氛下,其固相产物为C 60、B 12 H 16、B 2O 3以及硼酸;将HMX与BHN-10燃料混合后,电爆轰冲击固体产物主要以非晶态的C和B形式存在。
To explore the stability of high-energy fuels under strong shock wave effect and simulate the practical enviroment,the explosion and electric detonation shock methods were used to study the stability of boron hydride salt(BHN-10)under shock effect as well as the gas and solid products produced by the decomposition of the boron hydride salt.Moreover,HMX was introduced in BHN-10 to investigate the effect on the decomposition efficiency of BHN-10.The results show that BHN-10 has good stability to the impact of detonation shock generated by single explosive.The shock wave of 1.0 GPa magnitude generated by single explosive detonation cannot promote the decomposition of BHN-10.BHN-10 has relatively low stability under the shock of electric detonation.The interaction of shock and heat generated by the plasma electric detonation method result in the decomposition of BHN-10,and the organic flammable gas products with high calorific value contain triethylamine,nitrile,paraffin,olefin or alkyne.After adding HMX into the BHN-10,the length of the carbon chain of the gas products is shortened and less than 4 carbon atoms except for triethylamine.The addition of HMX can greatly improve the decomposition efficiency of the BHN-10 fuel,and generate low carbon chain flammable gases with a higher proportion.Under the N 2 atmosphere,the solid decomposition products of BHN-10 contain C 60 and orthorhombic B 12 H 16.Under the air atmosphere,the solid decomposition products are C 60,B 12 H 16,B 2O 3 and boric acid.After adding HMX,the solid products from the decomposition of the BHN-10 are mainly amorphous phases of C and B elements.
