Embodiment

[0033] 1 implement according to the best formula (mass %) as follows:

[0034] 97 ammonium nitrate

[0035] 3 explosion-proof agent

[0036] Wherein composite explosion-proof agent implements by following optimal composition (mass %):

[0037] 75 explosion suppressant: aluminum sulfate

[0038] 10 Flame retardant: Potassium dihydrogen phosphate

[0039] 5 Anti-crystal change agent: sodium lignosulfonate

[0040] 5 heat resistant agent: sodium methylene benzyl naphthalene sulfonate

[0041] 5 anti-penetration agent: polyvinyl butyral

[0042] 1.1 Preparation of anti-explosion agent: First, bake 5kg of sodium methylene benzylnaphthalene sulfonate in an oven at 90-100°C for 4 hours, and put 10kg of potassium dihydrogen phosphate and 75kg of aluminum sulfate in a ball mill with a speed of 40r / min respectively Grinding, the fineness needs to be more than 425μm and 80% or more; then add the above three qualified raw materials together with 5kg sodium lignosulfonate and 5kg pol...

Abstract

The invention provides a loose explosion proof ammonium nitrate for agricultural use, which is characterized by containing water soluble powdery antidetonant, and preparation thereof. The invention aims to solve the technological defects of antidetonants for ammonium nitrate modification developed in the prior art such as undesired water solubility in practical use, easy separator of ammonium nitrate from the mixture, easiness in blocking pelleting spray by the antidetonant, bad explosion prevention effect, hardening easiness during the product storage. The water soluble powdery antidetonant includes an explosion inhibitor, a flame retardant, a crystallization resistant, a heat resistant, and a penetration inhibitor. The explosion inhibitor and the ammonium nitrate liquor is added into a mixing groove in front of the pelleting spray at the same time and stirred uniformed, continuously pelleted by a rotation spray so that explosion proof granular ammonium nitrate which is loose, explosion resistant and unable to be recovered is obtained. The invention also can be used as an effective antidetonant modified from powdery crystal ammonium nitrate.

Description

technical field [0001] The invention relates to an agricultural anti-explosion ammonium nitrate and a preparation method thereof, belonging to the modification of ammonium nitrate, in particular to an anti-explosion ammonium nitrate suitable for preparing loose, anti-explosion and irreducible properties and a preparation method thereof. The modified anti-explosion ammonium nitrate consists of ammonium nitrate and a water-soluble anti-explosion agent. Background technique [0002] Ammonium nitrate (AN) plays a very important role in industrial and agricultural production and national defense. It is not only a kind of quick-acting nitrogen fertilizer, but also an important raw material for preparing various explosives. Insecurity is brought about by the society. In order to eliminate the illegal use of ammonium nitrate to fry explosives from the source and ensure the safety of agricultural ammonium nitrate transportation and social stability, the Chinese government issued the ...
