Description
Technical field
The present invention is a kind of explosion proof ammonium nitrate for agricultural, belongs to modification of ammonium nitrate, is mainly used in agricultural fertilising, is made up of ammonium nitrate and detonation suppressor.
Background technology
Ammonium nitrate is the main raw material of making civil explosive, is again a kind of agrochemical, is very easily fried into explosive, serious harm public safety privately.In order to stop from the source with the private illegal activities of frying explosive of ammonium nitrate, must be to the ammonium nitrate strict control of keeping under strict control.Forbid ammonium nitrate as fertilizer selling.Simultaneously,, allow that ammonium nitrate is done modification and handle, make it to lose explosive and unreducible back as fertilizer selling, use in view of the needs of some farm crop to nitrate fertilizer.
In order to solve the requirement of modification of ammonium nitrate, the patent of report about modification of ammonium nitrate arranged all both at home and abroad.United States Patent (USP) 3,366,468 have reported a kind of method that reduces the ammonium nitrate susceptibility, add ammonium hydrogen phosphate or the primary ammonium phosphate of 5%-10% in ammonium nitrate.Phosphoric acid salt is generally made fire retardant, and it has fire retardation, is used in the explosive, can play prevention igniting to a certain degree, the generation and the transmission of prevention focus.
Chinese patent application number 02156254.7 has been reported a kind of " Ammonium nitrate explosion-proof agent ", add in the ammonium nitrate and make passivation ammonium nitrate, add detonation suppressor in this ammonium nitrate and adopt physical mixed method, its lack of homogeneity, and be to rely on detonation suppressor to reduce sensitivity, its consumption is big, cost is high.
Summary of the invention
The objective of the invention is to overcome disadvantages of background technology, design a kind of detonation suppressor and make the modification of ammonium nitrate own, reduce blast performance, the explosion proof ammonium nitrate for agricultural that the detonation suppressor consumption is few, cost is low.
Design of the present invention, to achieve these goals, according to Theory of Detonation: the crystalline lattice energy is big more, and its detonation sensitivity is more little.In addition, the charge density of explosive is big more, and detonation sensitivity is just more little, and the detonation sensitivity of explosive reduces along with the increase of the charge density of explosive.If we can develop a kind of additive, can generate big and also big eutectic or the mixed crystal thing of density of lattice energy with ammonium nitrate, just might reduce the detonation sensitivity of ammonium nitrate.Select toughener for use, can strengthen the intensity and the density of ammonium nitrate, and can generate fine and close eutectic or mixed crystal with ammonium nitrate, heat is big, lattice energy is big and toughener itself generates, and so just can stop the propagation of detonation wave in ammonium nitrate; Select for use deterrent to reduce the Sensitivity to Primary Explosion of ammonium nitrate; Select stablizer for use, can absorb certain detonation energy, improve the thermostability of ammonium nitrate.Toughener, deterrent and stablizer three are mixed into detonation suppressor.Detonation suppressor is added in the building-up reactions that generates ammonium nitrate,, separate out ammonium nitrate and detonation suppressor eutectic or part mixed crystal with the ammonium nitrate cocrystallization.
