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.

Abstract

The invention relates to an emulsion powder explosive that has low detonation velocity. The feature is that it has 80-95 portions emulsion powder explosive, 5-20 portions diluents agent, and 0-10 portions density regulator. It could gain emulsion powder explosive that has 2000-2800m / s low detonation velocity, and density at 0.5-1.0g / cm3. The invention could lower the cost to 10-15% and has no adverse effect to explosive.

Description

technical field [0001] The invention is an improvement to the emulsified powder explosive for engineering blasting, in particular to an emulsified powder explosive with low detonation velocity. Background technique [0002] Existing emulsified powder explosives, such as those disclosed in Chinese patents CN91107080.X and CN93117971.8, consist of an oxidizing agent and an oil phase reducing agent. This type of explosive has a high detonation velocity, generally between 3800-4200m / s. For some small resistance lines and soft rock blasting, the blasting effect of this kind of high-detonation velocity explosive is not ideal, and the cost of the explosive is relatively high. There is room for improvement. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the above-mentioned prior art, and provide a kind of emulsion powder explosive with low detonation velocity and lower cost. [0004] The object of the present invention i...
