Embodiment 1
[0053] This embodiment provides an emulsion explosive for high-stability smooth blasting. The emulsion explosive includes the following components in parts by mass:
[0054] Solid amine nitrate: 30 parts, sodium nitrate: 7 parts, methylamine nitrate: 10 parts, aluminum powder: 8 parts, water: 7 parts, density regulator: 7 parts, stearic acid: 5 parts, crosslinking agent: 4 Parts, foaming cream: 1 part, composite emulsifier: 2 parts, sensitizer: 5 parts, pentaerythritol tetranitrate: 0.5 part.
[0055] The density regulator is a mixture of glass microspheres, expanded perlite and hollow plastic balls. The glass microbeads are calculated by mass ratio: expanded perlite: hollow plastic balls = 2:1:1; the crosslinking agent is borax The composite emulsifier is composed of modified soybean phospholipid, high-viscosity emulsifier Span-80 and polyolefin derivative (LR-1); the sensitizer is sodium nitrite.
[0056] The compound emulsifier is calculated by mass parts, modified soybean phosph...
