The invention has the beneficial effects as follows:
Ammonium nitrate in the present invention: 60-65%, SODIUMNITRATE: 8-11%, SODIUMNITRATE can provide part oxygen, plays part " flame arrest " and reduces crystallization point effect, improving ammonium nitrate content as far as possible, reducing SODIUMNITRATE content, is conducive to the stability improving detonation sensitivity.
With the addition of habit modifier in the present invention, as the habit modifier of ammonium nitrate, in order to control the grain development of ammonium nitrate, avoid occurring square or column macrobead, thus improve the plasticity-of explosive, improve its detonation susceptibility.
Flame-cooling agent is with the addition of in the present invention, flame-cooling agent can reduce the quick-fried heat of its quick-fried gentleness when Lithium Oxides By Detonation With Emulsion Explosive, shorten the length of explosive flame and hold-time, thus ensure its Fire behavior and flame-cooling agent reduces costs flame arrest better effects if by composite the forming of NaCl and KCl; Meanwhile, the flame-cooling agent in the present invention all adds in oxidizing agent solution, and this mode can meet physical sensitization product again can adaptation chemical sensitization product requirement, and constant product quality is easy to operate, and flame-cooling agent consumption is few again, and flame arrest is effective, and degree of safety is high; Containing a certain amount of Industrial Salt and water in emulsion explosive for coal mine, and when the flame-cooling agent in emulsion explosive is mainly dissolved in aqueous oxidizing agent solution, form tiny crystal grains in blast process, have larger specific surface area, be uniformly dispersed, flame arrest is effective; Appropriate flame-cooling agent can ensure the degree of safety of emulsion explosive for coal mine, but excessive detonation sensitivity and the brisance of making again reduces, and therefore the addition of flame-cooling agent should be as the criterion with the security meeting emulsion explosive for coal mine.
The advantage that flame-cooling agent joins in aqueous oxidizing agent solution is: (1) can change oxidizing agent solution crystalline form, is beneficial to and prevents phase transformation, improves system stability and product storage period.(2) be conducive to inorganic chemistry sensitization, be conducive to reducing costs, Industrial Salt is without the need to again processing, simple to operate.
The present invention selects the measure such as oxygenant, flame-cooling agent, water, combustible agent massfraction be suitable for improve its security, Sensitivity to Primary Explosion and detonation stability.
Adopt the water of 8-10% in the present invention, the high temperature produced in explosive charge process, by water vapor, consumes part energy, the heat produced during explosive charge can be made like this to reduce by 230 kJ/kg.
In aqueous oxidizing agent solution, a kind of polyvalent alcohol and k is added in the present invention
12tensio-active agent, as composite additive, is used for reducing aqueous phase crystallization point, can forms hydrogen bond, owing to reducing the reactive force between ammonium nitrate molecule, thus its crystallization point is declined between ammonium nitrate molecule and polyvalent alcohol; Meanwhile, add flame-cooling agent in aqueous phase and also change system crystalline form further, in being beneficial to, low temperature emulsified.
Have selected the compound oil phase material based on compound wax, this compound wax calorific value is high, modest viscosity, there is suitable dropping point and oil-contg, there is good matching with emulsifying agent, another add the Microcrystalline Wax that a small amount of crystal grain is comparatively thin, fusing point is higher, make the emulsion explosive for coal mine form that obtains harder, be easy to suction and slip gas, be conducive to the detonation sensitivity and the product shelf life that improve explosive.
Emulsifying agent quality, content and viscosity have obvious impact to the quality of emulsifying process, emulsoid, interior phase size of particles, blast performance, stability in storage etc.Single dehydrating sorbitol monooleate (Span-80) has the advantage that initial performance is good, emulsion strength is low and raw material is easy to get, but its emulsion explosive poor performance storage period of producing, especially unfavorable to the explosive product shelf lives of chemical sensitization; Succimide has that relative molecular weight is large, viscosity is high, water insoluble, be soluble in machine oil and the feature such as organic solvent, stable performance own, but emulsion strength requires high, unfavorable in security.The invention select that both are composite, dehydrating sorbitol monooleate is got: succimide is 1:1 or 1.6:0.4 mixing time composite, add a certain amount of emulsion adjuvant (DRQ) simultaneously, it contributes to improving easy milkiness and explosive stability in storage, to have selected the mixed emulsifier that both have been mixed to form in the present invention, had that viscosity is large, the feature such as good film-forming property and molecular structure stabilized, both solved viscosity problem, obtain again good emulsifying effectiveness, product shelf-stable.
DRQ type emulsion adjuvant is chosen in the present invention, this emulsion adjuvant is polar organic matter, good matching can be had with emulsifying agent, good emulsification promoter action can be played, during emulsifying effect, original intermolecular strong interaction and interfacial tension is made to be down to lower, interfacial adsorption strengthens, and intermolecular arrangements is more tight, and composite membrane intensity is improved, form fastening interfacial film, thus improve easy milkiness.
The present invention's three grades of allowed for use in coal mines safety and environmental protection emulsion explosives are not owing to adding flame-cooling agent and adopting the technical measures such as compound emulsifying agent, additive, emulsion adjuvant, whipping agent in combustiblematerials solution, outside three grades of coal-mining emulsifying explosives the are had performance advantage such as brisance, gap distance and medicine body be tack-free, its explosion velocity and capacity for work higher, storage period is longer, hardness is larger, show good powder stick formability and general applicability, there are very strong using value and market outlook.
