preparation example Construction

[0021] The above-mentioned ammonium nitrate composite antiknock agent is used in ammonium nitrate fertilizer to prepare high-nitrogen nitro compound fertilizer, which includes 98.5-99% of ammonium nitrate and 1-1.5% of the above-mentioned ammonium nitrate composite antiknock agent. The preparation method of the high-nitrogen nitro compound fertilizer comprises the following steps: in the mixing tank of the ammonium nitrate production line, inject molten ammonium nitrate mother liquor, then add powdered ammonium nitrate composite anti-knock agent and mix, and open the mixing tank after mixing evenly The tanks are all poured, and the granular high-nitrogen nitro compound fertilizer is produced by continuous granulation through the rotary nozzle. The invention increases the particle strength of the product through physical eutectic, and the particle strength of the obtained product is greater than 30N. Through the principle of physical eutectic enhanced passivation and intermolecu...

Embodiment 1

[0024] The ammonium nitrate composite antiknock agent comprises the following components in mass percentage: 60% of ammonium chloride, 20% of aluminum sulfate, 10% of melamine, and 10% of sodium methylene bis-naphthalenesulfonate. During preparation, first bake 5kg of sodium methylene bis-naphthalene sulfonate in an oven at 90°C for 4 hours, and grind 10kg of aluminum sulfate and 30kg of ammonium chloride in a ball mill with a speed of 40r / min to a particle size of 425μm. The particles reach more than 80%; then add the above three qualified raw materials together with 5kg of melamine into a mixer with double-layer helical structure, mix for 30 minutes, and discharge to obtain the ammonium nitrate composite antiknock agent.

Abstract

The invention relates to an ammonium nitrate composite antiknock agent, a high nitrogen nitro compound fertilizer and a preparation method of the high nitrogen nitro compound fertilizer. The ammoniumnitrate composite antiknock agent is prepared from the following components: 60-85% of an antiknock agent, 10-20% of a reinforcing agent, 2-10% of a nitrogen-rich agent and 3-10% of a stabilizer, wherein the antiknock agent is chloride; the reinforcing agent is inorganic sulfate; the nitrogen-rich agent is organic nitrogen heterocyclic cyanide and urea; and the stabilizer is an anionic surfactantwith naphthalene rings. The high nitrogen nitro compound fertilizer is prepared from 98.5-99% of ammonium nitrate and 1-1.5% of the ammonium nitrate composite antiknock agent. According to the invention, the particle strength of a product is increased by physical eutectic, and the particle strength of the obtained product is more than 30 N; through a physical eutectic enhancement passivation principle and an intermolecular complex chemical passivation technology, the high nitrogen nitro compound fertilizer product added with the composite antiknock agent is enabled to be stored for six months,and the antiknock performance can still be kept stable.

Description

technical field [0001] The invention belongs to the field of high-nitrogen nitro compound fertilizers, and specifically relates to an ammonium nitrate composite antiknock agent. In addition, the invention also relates to a high-nitrogen nitro compound fertilizer containing the ammonium nitrate composite antiknock agent and a preparation method thereof. Background technique [0002] Ammonium nitrate (AN) is a kind of quick-acting nitrogen fertilizer in agriculture, and the high-nitrogen nitro compound fertilizer containing 85% AN in the component is a widely used agricultural chemical fertilizer developed in modern times. However, the flammable and explosive properties of this kind of high-nitrogen nitro compound fertilizer not only bring major unstable factors to production, storage and transportation; moreover, this kind of fertilizer can be processed by simply mixing with combustibles such as diesel oil and wood flour. Become "earth explosives" and seriously bring unsafe f...
