Description
The present invention relates to a kind of explosive, particularly a kind of explosive-source explosive post and method for making thereof that is used for oil seismic exploration.
In the prior art, the explosive-source explosive post main charge has three kinds: an-tnt explosive, emulsion explosive and gelatinous explosive.At present, the an-tnt explosive of large usage quantity, its representative formula have three kinds: and high-density or high explosion velocity prescription (explosion velocity 〉=5000m/s): nitre ester ammonium 45%～55%, tritonal (TNT) 45%～50%, wood powder 2%～3%; Middle density or middle explosion velocity prescription (explosion velocity 4000～5000m/s): ammonium nitrate 60%～70%, TNT30%～35%, wood powder 3%～5%; Low density or low explosion velocity prescription (explosion velocity 3500～4000m/s): ammonium nitrate 80%～85%, TNT15%～18%, wood powder 3%～6%; Though the explosive-source explosive post of these three kinds of density or explosion velocity obtains using more widely in oil seismic exploration, but also have following problem: 1, TNT content is big in this explosive-source explosive post main charge, toxicity is high, in the manufacturing process, both be detrimental to health, again contaminate environment; 2, because TNT content is big, so the production cost height of main charge.
The objective of the invention is guaranteeing that the every performance index of explosive meet under the situation of GB, by the way of reduction TNT content, and provides a kind of explosive-source explosive post and method for making thereof for overcoming the deficiencies in the prior art.
The objective of the invention is to reach: adopt the bulk ammonium nitrate of lightweight among the CN91107051.6 to substitute common ammonium nitrate, can under the constant prerequisite of blast performance, reduce TNT content significantly by following technical scheme.For the explosive-source explosive post of high explosion velocity, its component and content (quality %) are: lightweight is bulk ammonium nitrate 68～75, wood powder 3.5～4.5, compound oil phase material 1.0～2.5, TNT20～25; For the explosive-source explosive post of middle waterfall speed, its component and content (quality %) are: lightweight is bulk ammonium nitrate 82～85, wood powder 3.5～4.5, compound oil phase material 1.0～2.5, TNT10～13; For the explosive-source explosive post of low waterfall speed, its component and content (quality %) are: lightweight is bulk ammonium nitrate 75～80, wood powder 16～20, compound oil phase material 1.0～2.5, TNT2.0～4.0; In the component of the explosive-source explosive post of above-mentioned three kinds of explosion velocities, the component of bulk ammonium nitrate and content (quality %) are: ammonium nitrate 99.7～99.9, octadecane amine acetate 0.1～0.3; The component of compound oil phase material and content (quality %) are: diesel oil 50～80, paraffin or compound wax 10～35, machine oil 5～15.
The method for making of the explosive-source explosive post of above-mentioned three kinds of explosion velocities is:
(1), ammonium nitrate is dissolved in the water, the concentration of its solution is 80～95 (quality %), and temperature is 110～140 ℃, adds the octadecane acetate then, carries out the vacuum crystallization subsequently under the vacuum of 0.085～0.098MPa, obtains the bulk ammonium nitrate of lightweight;
(2), bulk ammonium nitrate of lightweight and wood powder are mixed, temperature is 50～85 ℃;
(3), compound oil phase material and the material that obtained by (2) are mixed, temperature is 50～75 ℃;
(4), material that TNT and (3) are obtained mixes, temperature is 50～70 ℃;
(5), the material that (4) are obtained is cooled to and carries out powder charge below 45 ℃ and promptly obtain explosive-source explosive post, its moisture≤0.3%.
The present invention compared with prior art, its remarkable advantage is: 1, reduced the consumption of TNT significantly, alleviated to the harm of human body with to the pollution of environment; 2, the product percentage of initiation improves, and anti-moisture absorption, anti-caking effect also obtain bigger improvement; 3, the material cost of product has decline by a relatively large margin; 4, manufacture method is easy, reliable, is suitable for suitability for industrialized production, and the explosive-source explosive post that the present invention proposes is widely used in oil seismic exploration.
