Abstract: Based on the pressure desensitized and low power problems that traditional emulsion explosives exists in utilization,a hydrogen storage emulsion explosives sensitized by MgH₂ with chemical method was developed,and the foaming process is controlled effectively by coating MgH₂ with paraffin wax film.Shock wave dynamic pressure desensitization experiments and underwater explosion experiments are implemented,and experimental results show that compared with glass microspheres type of emulsion explosives,the shock wave peak pressure,shock wave energy and bubble energy of MgH₂ type of hydrogen storage emulsion explosives increased 20.5%,21.2% and 34.7% respectively,and it also has a brilliant dynamic pressure resist ability and storage stability.
