Abstract
An anti-caking agent for ammonium nitrate is prepared from long-chain alkylamine, disperser, penetrant, activated filler and water-proofing agent through compounding. The ammonium nitrate to which said anti-caking agent has added features excellent comprehensive properties including moisture-proofing, no caking, and good looseness and granular strength during storage.
Description
The present invention relates to a kind of additive of ammonium nitrate, especially a kind of anti-hard caking agent of ammonium nitrate.
Ammonium nitrate is a kind of agrochemical efficiently, also has a wide range of applications industrial, as is used to make explosive, refrigerant and medicine etc.But, because ammonium nitrate has physical propertys such as easy water absorbability, particulate is easily fixed with warm morphotrophy with under being subjected to heavily to push, make ammonium nitrate when storing, can lose loose character and sclerosis takes place and lump, cause great difficulty not only for storage, transportation and use, and in its use shattering process, unsafe factor lies dormant.
United States Patent (USP) 4220463 discloses a kind of C of using
12～C
18Alkylamine applies ammonium nitrate granule, is coated with skim mineral oil again, to prevent the ammonium nitrate moisture absorption, adhesion caking.This patent adopts C
12～C
18Alkylamine and coated with mineral oil ammonium nitrate granule top layer, its viscosity is big, mutual solubility is little, distributes more loose at ammonium nitrate surface, the anti-caking block period is short, and ammonium nitrate granule is carried out the coating processing of alkylamine, mineral oil again, and its technology is complicated, also gives to produce and use is made troubles.
The present invention's purpose provides a kind of ammonium nitrate prevented from caking in storage period that makes, and can keep its shatter value and granule strength, and net effect is good, produces and moistureproof agglomeration agent easy to use.
For achieving the above object, the technical solution used in the present invention is: at the crystalline structure and the physical property of ammonium nitrate, design is adopted and by the quality proportioning is: 40～60 chain alkyl amine: 15～25 dispersion agents: 5～15 permeate agents: 8～18 reinforcing fillers: 6～16 water-resisting agents are total to the composite polynary composite anticaking piece agent that is made for.Wherein: chain alkyl amine is selected C for use
16～C
18Kiber alkyl amine or hydrogenated-tallow group primary amine or tallow base primary amine or cocounut oil kiber alkyl amine a kind of; Dispersion agent selects that the anti-polyoxyethylenated alcohol TW's of sodium methylene bis-naphthalene sulfonate or fat is a kind of for use; Permeate agent is selected maleic acid di-sec-octyl sodium sulfonate for use or is drawn back a kind of of powder; Reinforcing filler is selected a kind of of atlapulgite or wilkinite or montmorillonite for use; Water-resisting agent is selected a kind of of stearic acid or stearate or paraffin for use.Proportioning (in mass) by anti-hard caking agent and ammonium nitrate is 0.05～0.2 anti-hard caking agent: 100 ammonium nitrate, in the molten state ammonium nitrate that directly joins after the anti-hard caking agent metering before the granulation nozzle, advance the ammonium nitrate product that the nozzle mixing granulation promptly makes moistureproof anti-caking.If make powdery ammonium nitrate, will join in the crystallizing pond after the anti-hard caking agent metering.
The present invention has selected the composite ammonium nitrate anti-hard caking agent system of making polynary compound, performance complement of kinds of surface promoting agent for use.It has improved the ammonium nitrate crystal structure that generates, just anti-hard caking agent and ammonium nitrate have formed even mixed crystal crystal, become loose stable crystalline forms, controlled the crystal conversion phenomenon effectively, and in crystal, form the insoluble impurities nucleus, improved crystal grain intensity, also formed film, had the wet protection against the tide of resistance and crystal grain is isolated mutually prevent the agglutinating effect on crystalline surface.
The present invention compared with prior art has the following advantages and positively effect: (1) anti-hard caking agent consumption of the present invention is few, and effect is obvious.(2) add the ammonium nitrate that this anti-hard caking agent makes and have protection against the tide, prevented from caking, high comprehensive performances such as shatter value and granule strength in storage period.(3) use anti-hard caking agent of the present invention, productive expense is low, adding technology is simple, is applicable to suitability for industrialized production.
Specific embodiments of the invention are as follows:
Embodiment 1
Each set of dispense is than (by mass):
50 hydrogenated-tallow group primary amine (amine 86)
18 dispersion agents: sodium methylene bis-naphthalene sulfonate (high molten N)
10 permeate agents: Nekal BX
12 reinforcing fillers: atlapulgite
10 water-resisting agents: stearic acid
After each component is equipped with by the said ratio amount, join grind in the ball mill mixed evenly after, weighing and bagging is the anti-hard caking agent product.
Press the anti-hard caking agent product that 0.1% of ammonium nitrate total amount adds above-mentioned preparation, contain in the strainer of molten state ammonium nitrate before the anti-hard caking agent metering is directly joined the granulation nozzle,, make ammonium nitrate product through the nozzle granulation.
Embodiment 2
Each set of dispense is than (in mass):
46 octadecyl primary amine
20 dispersion agents: fat is prevented polyoxyethylenated alcohol TW
8 permeate agents: maleic acid di-sec-octyl sodium sulfonate
10 reinforcing fillers: wilkinite
12 water-resisting agents: Zinic stearas
After each component is equipped with by the said ratio amount, join in the ball mill ground and mixed evenly after, weighing and bagging is the anti-hard caking agent product.
Press 0.08% of ammonium nitrate total mass and add the anti-hard caking agent product, the anti-hard caking agent metering is directly joined before the granulation nozzle in the molten state ammonium nitrate,, make moistureproof anti-caking ammonium nitrate product through the nozzle mixing granulation.
The ammonium nitrate product that utilizes above-mentioned production technique to manufacture experimently, its shatter value is 100% after testing, ultimate compression strength is the 8.1N/ particle.Storing and detecting shatter value in three months is 96%, and granule strength is the 6.8N/ particle, and the product appearance physical condition is good, non-sclerous, the nothing caking.
