Another object of the present invention provides that a kind of blast performance meets national standard, is difficult for moisture absorption, the preparation technology of the hardened waterproof type rock swelling ammonium nitrate explosive that do not lump.
Purpose of the present invention is achieved through the following technical solutions:
The component of waterproof type rock swelling ammonium nitrate explosive is by mass percentage by 90%~94% nitrate oxidizer (expanded ammonium nitrate), 3%~5% combustible agent (wood powder), 3%~5% compounded oil phase composite.Nitrate oxidizer wherein is that nitrate oxidizer and moisture content are mixed into the expanded ammonium nitrate that the water post crystallization makes after expanded, combustible agent is the mixture of wood powder or coal dust or wood powder and coal dust, and compound oil phase is explosive special-purpose grease, extraordinary agent and surfactant mixtures;
The consumption of each component can be 10%~62.5% for the explosive special-purpose grease in the compounded oil phase mixture, and extraordinary agent is 32.5%~85%, and tensio-active agent is 5%~15%;
Tensio-active agent can be stearylamine, polyacrylamide;
Extraordinary agent can be Vaseline, slack wax, Vaseline and machine oil mixture, Vaseline and low temperature coal-tar pitch mixture, Vaseline and machine oil and mineral wax mixture, slack wax and machine oil mixture, slack wax and low temperature coal-tar pitch mixture, low temperature coal-tar pitch and diesel fuel mixtures;
Extraordinary agent major requirement: a, has the higher combustion heat; B, with ammonium nitrate higher sticking power is arranged; C, be easy to the ammonium nitrate particle internal penetration with at surface spreading; D, has stronger hydrophobic nature; E, have processibility and lower cost preferably.Just mainly consider its film-forming properties, toughness, suitable viscosity and denseness should be arranged, should consider also that simultaneously raw material sources are rich and cheap.
Its technology of waterproof type rock swelling ammonium nitrate explosive and the step that prepare above-mentioned component and proportioning are as follows:
(1) take by weighing each component by proportional quantity, nitrate oxidizer and water are mixed into water, crystallization is expanded, makes expanded ammonium nitrate;
(2) explosive special-purpose grease and extraordinary agent is fully melt-blended, add the compound oil phase of the melt-blended one-tenth of stearylamine or polyacrylamide again;
(3) the expanded ammonium nitrate that makes in the abovementioned steps, the compounded oil mixture together with exsiccant wood powder or coal dust or wood powder and coal dust, three components mix continuously, promptly make waterproof type rock swelling ammonium nitrate explosive.
Above-mentioned step (2) can be for earlier fully melt-blended with explosive special-purpose grease and extraordinary agent, after temperature reaches 80 ℃~100 ℃, adds stearylamine again or polyacrylamide is melt-blended, heats up to reach 110 ℃~120 ℃ technological temperatures and make compound oil phase;
Temperature range when three components mix continuously in the above-mentioned step (3) can be at 50 ℃~90 ℃.
The explosive special-purpose grease meets following condition in the above-mentioned component:

The waterproof type bulking ammonium nitrate explosive that above-mentioned component proportioning and preparation method obtain: 1. blast performance meets national standard; 2. water resistance reaches: powder stick is embedded in the mud slurry gap distance 3cm after 2 hours, is dipped in the depth of water 30cm water gap distance 2cm after 1 hour.And the sclerosis of can not luming, the medicinal powder free-running property is also fine simultaneously.
Waterproof type rock swelling ammonium nitrate explosive of the present invention, with Vaseline, slack wax or and machine oil, the low temperature coal-tar pitch, paraffin, the mixture with waterproof action that the mixture of diesel oil and tensio-active agent are formed has substituted the compound oil phase in original rock expanded ammonium nitrate explosive component, make expanded ammonium nitrate after pulverizing, produce a large amount of new sections, because being formed closely knit firm oil film by water-proof material coats, and stopped production process, storage and transport process and use and air, water contact back moisture absorption causes product performance to descend, also have because selected the strongest aliphatic hydrocarbon base class tensio-active agent of hydrophobicity for use, it makes expanded ammonium nitrate solid surface wetting ability become the surface of hydrophobic nature, thereby the generation and the schedule speed that have stoped moisture absorption, reached non-hygroscopic at wet environment, the slower effect of moisture absorption in the water environment, also has this formulation product owing to do not lump, free-running property is good, be easy to the powder charge packing in process of production, when the terminal user uses, particularly in the coupling charging process, improve loading rate to a great extent, reduced labour cost.

Above-mentioned best product is through carrying out shelf test, and the performance of product sees the following form in the storage process:
Test-results shows that waterproof type rock swelling ammonium nitrate explosive of the present invention has good blast performance, water resistance and shelf characteric.This formulation product free-running property is good simultaneously, is easy to powder charge at production line.The use waterproof effect is obvious, finds no the sclerosis caking phenomenon.Simultaneously, the bulking ammonium nitrate explosive of this waterproof type is in the coupling charging process, free-running property is good, improved loading rate to a great extent, especially mould the expanded powder stick of wound packages major diameter waterproof type and in medium-length hole blasting, replace the emulsion explosive use, ponding is in various degree all arranged in the hole, reach 3 hours in the expanded powder stick of the waterproof type activity duration, explosion is still very successful.Show the waterproof type bulking ammonium nitrate explosive aspect water-repellancy, can satisfy the needs of the medium-length hole blasting of ponding substantially, thereby widened the use range of bulking ammonium nitrate explosive greatly.
