Its advantages are high safety and performance, uniform explosion transmission and low cost.
Description
One, affiliated technical field
The present invention relates to a kind of low explosive and method for making thereof, particularly a kind of low explosion velocity bulking ammonium nitrate explosive and method for making thereof.
Two, background technology
Low explosive is meant the lower explosive of its limit explosion velocity of a class, is widely used in metallic explosive welding (compound), in the fields such as the coupling charging of smooth blasting.The preparation method of relevant low explosive, existing both at home and abroad the report, as document 1, Ricard.Low Detonation Velocity Explosive Composition.USP, 4490196,1984; This patent is an explosive component with single chmical compound explosives such as TNT, RDX, PETN, as binding agent, in manufacturing processed, produces bubble with air-blowing or chemical blowing process with high molecule plastic, obtains the foamed explosive of low explosion velocity after the curing.Document 2, Lv Chunxu etc. industrial mixed explosives with low detonation speed. Chinese patent, 89105369,1990; This patent is with heavy metal oxide or have the Mysticum gunpowder of very low explosion velocity, removes to dilute No. 2 rock dynamites (containing the TNT component) with higher explosion velocity, thereby obtains a kind of 2000ms of having
-1～2500ms
-1The industrial mixed explosives with low detonation speed of explosion velocity.The low explosive of above-mentioned reported in literature exists following defective: (1) all contains high explosive RDX, TNT, PETN etc., not only makes product cost high, and has increased the insecurity in production, storage, transportation, the use; (2) adopt heavy metal oxide to make thinner, cause environmental pollution after the blast.
Three, summary of the invention
The object of the present invention is to provide a kind ofly do not contain high explosive and heavy metal components, blast performance is good, nontoxic, and fairly simple low explosion velocity bulking ammonium nitrate explosive and the method for making thereof of production technique.
The technical solution that realizes the object of the invention is: a kind of low explosion velocity bulking ammonium nitrate explosive, it is characterized in that it is to be made by following component and prescription (quality %) combination drying: ammonium nitrate 71～84, tensio-active agent 0.08～0.2 (adding), compound oil phase material 3～6, wood powder 1～6, thinner 7～16, described compound oil phase material is made up of following component and prescription (quality %): diesel oil 40～60, paraffin 40～60, tensio-active agent can be octadecane amine nitrate, octadecane amine vitriol, octadecane amine acetate or sodium lauryl sulphate.Thinner can be perlite, hollow glass micro-ball or mineral micro powder.
A kind of low explosion velocity bulking ammonium nitrate explosive method for making, it is characterized in that its manufacturing technology steps is: common ammonium nitrate is added 7%～11% water of ammonium nitrate quality to the first step and 0.08%～0.2% tensio-active agent dissolves, and the solution temperature after the dissolving is 110 ℃～140 ℃; Second step with above-mentioned solution vacuum tightness for-0.085MPa～-0.098MPa under drying under reduced pressure 5min～20min obtain expanded ammonium nitrate; The 3rd step mixed expanded ammonium nitrate in wheel roller or mixing screw with compounded oil, wood powder, thinner; The material of the 4th step with the 3rd step gained is cooled to below 40 ℃, carries out the powder charge packing, promptly makes low explosion velocity bulking ammonium nitrate explosive.
Principle of the present invention is: the theoretical and modern surface active process based on explosive detonation, add low quantity of surfactant with common ammonium nitrate, through dissolving, vacuum puffed crystallization makes the expanded ammonium nitrate with autosensibilization constitutional features, as oxygenant, as reductive agent, and be aided with the micropore material with it as thinner with composite fuel oil and wood powder, under certain processing condition, mix to form to have and hang down explosion velocity and the good industrial mixed explosive of propagation of explosion.
The present invention compared with prior art, its remarkable advantage is: 1. do not contain the high explosive component in the prescription, help safety in production, use, environmentally safe; 2. blast performance is good, the propagation of explosion good uniformity; 3. material cost is low, and manufacture method is simple, reliable, is suitable for suitability for industrialized production.
