Solid-state emulsion explosive seismic source grain and preparation method thereof

The invention discloses a solid-state emulsion explosive seismic source grain and a preparation method thereof. The preparation method comprises the steps of: heating a mixture composed of an oxidizing agent, a crystal form modifying agent and water for dissolving to form an oxidizing agent solution; heating a mixture composed of compound wax and an emulsifying agent for melting to form a combustible solution; adding the oxidizing agent solution into the combustible solution, and stirring to form a water-in-oil type mixture; adding a density modifying agent in the water-in-oil type mixture and stirring to obtain main charge of the solid-state emulsion explosive seismic source grain; and filling the obtained main charge in a charge shell of the grain with required specifications, pressing into a detonator base with an explosive-initiating grain, and sealing with a sealant to obtain the solid-state emulsion explosive seismic source grain. The solid-state emulsion explosive seismic source grain prepared by the p
