Embodiment 1

[0022] A water-gel explosive, including a sensitizer, a density regulator, an explosion-increasing metal powder, an oxidizing agent, a reducing agent, and a cross-linking agent. By controlling the content of the density regulator, the density of the water-gel explosive is controlled within a certain range. When detonating roll by roll, when the water-gel explosive is subjected to a strong compression wave, the existing density regulator provides a hot spot to make the explosive detonate under pressure; it is sensitized by a sensitizer and the metal powder absorbs microbubbles to sensitize Combining with the density regulator as the sensitization of the bubble carrier, it can ensure the detonation ability and explosive performance of the water gel explosive in the environment with a water depth of 50 meters or below.

[0023] Ammonium nitrate and sodium nitrate are oxidizing agents, and coating-grade aluminum powder is a reducing agent.

Embodiment 2

[0025] On the basis of Example 1, preferably, the sensitizer is a combination of one or more of methylamine nitrate aqueous solution, nitro compounds, and nitrate compounds; by controlling the sensitizer content within a certain range , when the water-gel explosive is subjected to a strong compression wave, the cross-linked structure is destroyed, and the explosive changes from gel to paste, but the liquid sensitizer forms a continuous phase, which is distributed throughout the explosive, and is not easily affected by the compression wave. Destruction, when the water-gel explosive detonates, it is easy to be excited and detonated, which plays a sensitization role and makes the explosive detonate completely.

[0026] Preferably, the explosion-increasing metal powder is paint-grade aluminum powder, and a large number of microbubbles are adsorbed on the surface, which are dispersed in the drug body. When excited, the bubbles attached to the surface of the aluminum powder will form...

Embodiment 3

[0035] As a preference of Embodiment 1 or 2, the water-gel explosive consists of at least 35.0-40.0% aqueous solution of methylamine nitrate with a concentration of 78-87%, 25.0-30.0% aqueous solution of ammonium nitrate with a concentration of 70-78%, ammonium nitrate 12.0~17.0%, Sodium Nitrate 13.0~17.0%, Sesame Powder 0.80~1.20%, Coating Grade Aluminum Powder 2.0~3.0%, Density Regulator 2.0~3.0%, Hatching Protein 0.05~0.30%, Crosslinking Agent 0.10~0.30% %.

Abstract

The invention discloses a water-gel explosive which comprises a sensitizer, a density regulator, explosion enhancing metal powder, an oxidant, a reduction agent and a cross-linking agent. When explosives are subjected to explosion propagation roll by roll and the water-gel explosive bears the strong action of compression waves, a hot spot is provided by the existing density regulator, so that the explosive is detonated under pressure; by combining sensitization achieved through a sensitizer, sensitization achieved by absorbing micro bubbles through the explosion enhancing metal powder and sensitization achieved with the density regulator as a bubble carrier, the detonation sensitivity and explosion performance of the water-gel explosive in the environment with the water depth being 50 m or above are guaranteed. The detonation hot spot of the water-gel explosive is greatly increased by means of combined sensitization and material selection, the detonation sensitivity and explosion performance of the water-gel explosive are guaranteed when the explosive bears water static pressure at the water depth of 50 m or above, influences of deep water static pressure and permeation are effectively reduced, meanwhile the detonation sensitivity and explosion performance are guaranteed when the explosive bears strong compression waves in water, and an existing problem of deep water explosion is solved.

Description

technical field [0001] The invention relates to a water gel explosive, which belongs to the technical field of explosives. Background technique [0002] Water-gel explosives have many advantages such as good explosive performance, good safety performance, low environmental pollution, wide source of raw materials, simple processing technology, etc., especially in the environment with water. In the modern ocean development, the blasting application in deep water is particularly special. widely. If it is often necessary to destroy underwater oil pipelines, water pipelines, underwater optical cables, cables, and underwater hydraulic structures, etc., it is necessary to blast and clear sunken ships, abandoned oil well well pipes, and pile legs of water operating platforms when clearing waterways; Explosion of reefs and blasting of deep water cofferdams in the excavation of deep-water pipe trenches in marine development, construction of deep-water ports, and excavation of pile fo...
