Embodiment 1
[0009] Embodiment 1: Get polyisobutylene succinimide (trade name T155) 30%wt, paraffin wax 20%wt, ground wax 25%wt, rosin 25%wt, mix and heat 120-140 ℃ and stir to make oil phase spare. 90%wt ammonium nitrate and 4%wt water are mixed and heated at 125-145°C, stirred and dissolved to form an aqueous phase solution. The oil phase material prepared by 6%wt is mixed with the prepared water phase solution through the flow control of the water and oil phase, emulsified into a colloid by a continuous emulsifier, atomized by air flow, cooled and dried to obtain an emulsified powder explosive.
[0010] Get 85 parts of the prepared emulsified powdery explosive, mix with 15 parts of talcum powder evenly. The obtained branched drug has a density of 0.95g / cm3 and a detonation velocity of 2750m / s.
Embodiment 2
[0011] Embodiment 2: Take 90 parts of emulsified powdery explosives prepared in Example 1, add 5 parts of talcum powder, and mix evenly with 5 parts of perlite. The resulting branch density is 0.70g / cm 3 , detonation velocity 2450m / s.
Embodiment 3
[0012] Embodiment 3: Take 85 parts of emulsified powdery explosives obtained in Example 1, add 10 parts of talcum powder, and mix evenly with 5 parts of perlite. The obtained branched drug has a density of 0.80g / cm3 and a detonation velocity of 2250m / s.
