Abstract
The present invention provides an ammonium nitrate explosion prevention agent. The present invention comprises 100 portions of negative sensitizing agents, 0 to 10 portions of reinforcing agents, 0 to 10 portions of water repellent agents and 0 to 1 portion of dispersing agents by weight, wherein the negative sensitizing agents is at least one kind of materials selected from phosphate, nitrogen compounds and sulphate. The present invention has the advantages of stable performance, high reliability and high temperature resistance. After the addition of the present invention, ammonium nitrate loses the explosion performance. The present invention is mainly used for producing agricultural ammonium nitrate, has no influence on the fertilizer effect of the ammonium nitrate, has the synergistic effect, and ensures at least 35% of total nutrient.
Description
Technical field
The present invention relates to a kind of detonation suppressor, particularly relate to a kind of Ammonium nitrate explosion-proof agent.
Background technology
Ammonium nitrate is the main component of nitro-explosive, can be made into explosive behind the interpolation sensitizing agent.And agricultural ammonium nitrate is widely used as a kind of nitrogenous fertilizer.Because ammonium nitrate circulates extensively on market, wayward, might be used for making explosive by the lawless person, thereby cause factor leading to social instability to society, also influence the people's life, property safety, national requirements does not have explosion as the agricultural ammonium nitrate of chemical fertilizer for this reason, promptly can not be used to make explosive.
Summary of the invention
The objective of the invention is to overcome above-mentioned shortcoming, provide a kind of ammonium nitrate that can make to lose blast performance, and the fertilizer efficiency can not reduce ammonium nitrate again and make chemical fertilizer and use the time, be used to produce the Ammonium nitrate explosion-proof agent of agricultural ammonium nitrate.
The component of Ammonium nitrate explosion-proof agent of the present invention is calculated by weight and is comprised, negative sensitizing agent 100, toughener 0～10, hydrophober 0～10, dispersion agent 0～1.Wherein, negative sensitizing agent is at least a in phosphoric acid salt, nitrogenous compound and the vitriol.Its effect is that even add sensitizing agent in ammonium nitrate, ammonium nitrate can not explode yet, and sensitizing agent is played passivation.Phosphoric acid salt is one or more in sodium salt, sylvite, calcium salt, magnesium salts, aluminium salt, zinc salt, mantoquita, manganese salt, ammonium salt and the Ureaphil of phosphoric acid; Nitrogenous compound is one in Dyhard RU 100, ammonium chloride, ammonium sulfate, the urea or more than one; Vitriol is one or more in vitriolic sodium salt, sylvite, calcium salt, magnesium salts, aluminium salt, zinc salt, mantoquita, manganese salt and the ureasulfuric acid.The effect of toughener mainly is the intensity that increases ammonium nitrate, to reduce the dust in the particle, calculates by weight with 1～10 and is advisable, and can be in montmorillonite, potassium felspar sand, sepiolite, silica flour, the zeolite one or more; The effect of hydrophober is the humidity resistance that improves ammonium nitrate, helps transportation and stores, and calculates by weight with 1～10 and is advisable, and can adopt in paraffin, stearic acid, the sodium stearate one or more; The effect of dispersion agent is to improve detonation suppressor
Dispersiveness in ammonium nitrate, it is more even that detonation suppressor is disperseed in ammonium nitrate, calculates by weight with 0.1～1 and be advisable, and generally adopts sodium naphthasulfonate and alkyl sodium sulfonate.
Ammonium nitrate explosion-proof agent stable performance of the present invention, reliable, and Nai Gaore, make ammonium nitrate lose explosion-proof performance after adding the present invention, be mainly used in and produce agricultural ammonium nitrate (being passivation ammonium nitrate), not only do not influence the fertilizer efficiency of ammonium nitrate, and have synergism, guarantee that total nutrient is not less than 35%.Addition during use is generally 5%～50%.
