Problems solved by technology

Because ammonium nitrate is widely circulated in the market and is not easy to control, it may be used by criminals to make explosives, which will cause social instability and affect the lives and property safety of the people. Therefore, the country requires agricultural nitric acid used as fertilizer Ammonium is non-explosive, that is, it cannot be used to make explosives

Embodiment 1

[0008] The component distribution ratio (calculated by weight) of ammonium nitrate anti-knock agent of the present invention is as follows:

[0009] Ammonium phosphate 60

[0010] Ammonium chloride 25

[0011] Calcium sulfate 15

[0012] Zeolite 5

[0013] Sodium Naphthalene Sulfonate 0.5

[0014] Mix the above components evenly to obtain ammonium nitrate anti-knock agent. Its technical indicators are shown in Table 1. And the present invention is added in the ammonium nitrate and makes passivation ammonium nitrate, is mixed with ammonium oil explosive again and carries out explosion test, and its result is as shown in table 2.

[0015] Ammonium oil explosive formula is as follows:

[0016] Passivated ammonium nitrate 88.0±1.5%

[0017] Sulfur 4.5±0.5%

[0018] Wood flour 7.5±1.5%

[0019] Moisture content 0.40%

Embodiment 2

[0021] The component distribution ratio (calculated by weight) of ammonium nitrate anti-knock agent of the present invention is as follows:

[0022] Calcium hydrogen phosphate 50

[0023] Ammonium sulfate 50

[0024] Diatomaceous earth 9

[0025] Sodium Naphthalene Sulfonate 0.5

[0026] Mix the above components evenly to obtain ammonium nitrate anti-knock agent. Its technical indicators are shown in Table 1. And join the present invention in ammonium nitrate and make passivation ammonium nitrate, be mixed with ammonium oil explosive again and carry out explosion test, its result is as shown in table 3.

[0027] Ammonium oil explosive formula is as follows:

[0028] Passivated ammonium nitrate 92.0±1.5%

[0029] Sulfur 4.0±0.5%

[0030] Wood flour 4.0±0.5%

[0031] Moisture content 0.40%

Embodiment 3

[0033] The component distribution ratio (calculated by weight) of ammonium nitrate anti-knock agent of the present invention is as follows:

[0034] Urea phosphate 100

Abstract

An explosion-proof agent for ammonium nitrate contains desensitizer, inteneifying agent, hydrophobic agent and disperser. Said desensitizer is chosen from phosphate, nitrogen contained compound and sulfate. Its advantages are high ineffective of explosion function of ammonium nitrate, and high thermal stability.

Description

technical field [0001] The invention relates to an anti-knock agent, in particular to an ammonium nitrate anti-knock agent. Background technique [0002] Ammonium nitrate is the main component of nitro explosives, which can be made into explosives after adding a sensitizer. Agricultural ammonium nitrate has been widely used as a nitrogen fertilizer. Because ammonium nitrate is widely circulated in the market and is not easy to control, it may be used by criminals to make explosives, which will cause social instability and affect the lives and property safety of the people. Therefore, the country requires agricultural nitric acid used as fertilizer Ammonium is non-explosive, that is, it cannot be used to make explosives. Contents of the invention [0003] The purpose of the present invention is to overcome above-mentioned shortcoming, provide a kind of ammonium nitrate anti-explosion agent that can make ammonium nitrate lose explosive performance, and can not reduce the f...
