Embodiment

[0024] 1 implement according to the best formula (mass %) as follows:

[0025] 99.4 Ammonium nitrate

[0026] 0.6 Anti-knock agent

[0027] Wherein the component of composite explosion-proof agent is by mass %:

[0028]

[0029] 1.1 Preparation of anti-explosion agent: First, bake 6kg of xuanming powder in an oven at 90-100°C for 4 hours, and pulverize 12kg of hydrogenated oil and 75kg of ammonium chloride in a ball mill with a speed of 40r / min, and the fineness should exceed 425μm80% above; then add the above three qualified raw materials together with 4kg of melamine and 3kg of chitosan into a mixer with a double-layer spiral structure, mix for 30-40 minutes, and then discharge to make a product.

[0030] 1.2 Preparation of the present invention: first in the mixing tank of the ammonium nitrate production line produced by high-tower granulation, inject metering molten ammonium nitrate mother liquor (the mother liquor concentration is 99.0% to 99.5%, and the temperature ...

Abstract

The invention provides high-strength and high-stability agricultural anti-explosive ammonium nitrate and a preparation method thereof. The high-strength and high-stability agricultural anti-explosive ammonium nitrate is characterized by comprising a compound antidetonant. The high-strength and high-stability agricultural anti-explosive ammonium nitrate aims to solve the unsolved technical defects that the antidetonant for modifying ammonium nitrate researched by predecessors in actual use is great in antidetonant adding concentration, low in particle strength of product and poor in anti-explosive effect and the product is high in probability of hardening in the storage period, unstable and non-persistent in anti-explosive performance and the like. The compound antidetonant added consists of a detonant quenching agent, an enhancer, a stabilizer, a nitrogen-enriched passivator, an explosive-proof agent and the like. According to spray granulation continuous production of a high tower and the eutectic passivation principle of the antidetonant, the antidetonant is continuously added into a molten ammonium nitrate mother liquor mixing tank in front of a granulation nozzle to be uniformly mixed and is then continuously granulated by using a rotary nozzle to prepare the agricultural anti-explosive ammonium nitrate, wherein the particle strength is greater than 30N / particle and the looseness and the anti-detonating property are stable and persistent. The adding concentration of the high-strength and high-stability agricultural anti-explosive ammonium nitrate provided by the invention is 0.5-1.0%.

Description

technical field [0001] The invention relates to an anti-explosion ammonium nitrate for agriculture and a preparation method thereof, belonging to the modification of ammonium nitrate, in particular to an anti-explosion ammonium nitrate for agriculture with high strength and high stability and a preparation method thereof. The modified anti-explosion ammonium nitrate consists of ammonium nitrate and compound anti-explosion agent. Background technique [0002] Ammonium nitrate (AN) is a quick-acting nitrogen fertilizer in agriculture, it can be used as a propellant for solid rockets and a gas generating agent for aviation airbags in high-tech fields, and it is the main raw material for ammonium oil explosives in industry. Wood powder and other combustibles are processed into "earth explosives" without permission after simple mixing, which seriously brings unsafe factors to society. With the occurrence of many terrorist incidents that shocked the world, the hazards caused by t...
