Embodiment 1

[0020] The total mass of titanium hydride and emulsification matrix is ​​50 g, and the content of titanium hydride is 2% (=1 g) of the total mass. After titanium hydride was added to the emulsified matrix, the mixture was continuously stirred for 30 minutes with a stirrer, and the underwater explosion test was carried out after standing for 10 hours.

[0021] The formulation of the emulsified matrix used is the same as that of the prior art, and the basic formulation is shown in Table 1.

Abstract

The invention, belonging to the technical field of explosive preparation, particularly relates to an emulsion explosive prepared by using hydrogen storage materials. The explosive comprises an emulsion base and a sensitizing agent, wherein, the sensitizing agent is titanium hydride, the weight of the sensitizing agent accounts for 0.6-8 % of the total weight of the titanium hydride hydrogen storage emulsion explosive, and the purity of titanium hydride is no less than 95 %. During the detonation process, partial titanium hydride reacts with water in the emulsion base to release a little hydrogen, thus a certain foaming effect on the emulsion base is achieved, and the emulsion base is allowed to detonate, so that titanium hydride plays a role as the sensitizing agent. Simultaneously, the rest titanium hydride is subject to thermal decomposition under the effect of high temperature generated by the reaction between emulsion base and hydrogen bubbles to rapidly release hydrogen, and hydrogen continues participating the detonation reaction with the emulsion base to allow the output energy to contain the energy released by the emulsion base and titanium hydride together. The titanium hydride hydrogen storage emulsion explosive disclosed herein has the characteristics of low output explosion pressure, large impulse, long decay time, and high energy.

Description

technical field [0001] The invention belongs to the technical field of explosive preparation, and in particular relates to an emulsion explosive prepared by using a hydrogen storage substance. Background technique [0002] In the production process of emulsion explosives, the W / O emulsion is called emulsion matrix, which is the basic body of emulsion explosives and has good stability and potential detonation performance. The ammonium nitrate aqueous phase solution (oxidant) in the emulsified matrix is ​​dispersed into extremely small particles in the oil phase solution (combustible agent), and its core is a supersaturated inorganic salt solution, which is surrounded by a very thin but high-strength oil film. Shows a higher viscosity. The emulsion matrix is ​​an unsensitized emulsion explosive. It has a high density, requires a lot of detonation energy, and is very difficult to propagate. Therefore, in the process of preparing emulsion explosives, it must be sensitize...
