Description
Technical field
The invention belongs to composite fertilizer's technical field, more particularly to a kind of anticaking agent and its preparation method and application.
Background technology
120 sets or more are had at home using the device of high-tower melting granulation technology production fertilizer, reality at present
Production capacity accounts for about 20% or more of national composite fertilizer's yield.After chemical fertilizer raw material mixing, hygroscopicity can also change, high tower
Melt pelletization fertilizer is fusing urea（Or ammonium nitrate）Sprinkling pelleting is made after solution is mixed with other raw materials, and raw material mixing is more equal
It is even, but the variation of its hygroscopicity changes bigger compared with other handicraft products, it is easier to and moisture absorption, fertilizer product are being stored, were being transported
It is also easier in journey hardened.Therefore there is hardened phenomenon generally existing in high tower product, especially in the season of summer high temperature high humidity,
Hardened situation is particularly acute.
For high-tower melting granulation chemical fertilizer under formula and yield fixing situation, Granularity Distribution and appearance are also basicly stable,
In the case of strictly control product moisture and package temperature, to prevent fertilizer from moisture absorption, plate occurring in storage, transportational process
Knot influences application, and excellent anti hardening agent also to be selected to ensure the laxity of fertilizer.
There are two types of modes for the anti hardening agent that high-tower melting granulation chemical fertilizer plant uses at present：One is by alkylamine and mineral
The compositions such as oil directly carry out spraying package in package cylinder；One is inert material coating+machinery oil（Or animal and vegetable oil）,
Anti-compaction oil is sprayed in package cylinder and anti-compaction powder is added is wrapped up.
Such as application No. is the patents of CN201710101272 to disclose a kind of anti hardening agent of high tower urea-based fertilizer, it includes
45-48 parts of consistent lubricant, 3-15 parts of epoxy resin, 10-35 parts of paraffin, 1-10 parts of fatty acid salt, 1-10 parts of primary amine, stearic acid 1-10
Part, the consistent lubricant be low acid value palm oil or coconut oil, the fatty acid salt be fatty acid carbons coefficient be 10-18, fat
The metal of hydrochlorate is sodium or potassium, and also discloses its preparation method, which presses high tower urea-based fertilizer total amount
0.1-0.5% use.
Such as application No. is the patents of CN201310567304.1 to disclose a kind of inert material fertilizer anti-caking agents, it includes
Natural crystal powder 45-85%, modifying agent 5-20%, modified plastics 10%-50%, the natural crystal powder are with stratiform knot
The mineral dust of structure and water swelling disintegrating property, the modifying agent are silane coupling agent, phosphoric acid ester coupling agent, titanate esters
Class coupling agent, stearic acid and its esters, oleamide, higher alcohols, C14-C22 one or more of alkylamine mixing
Object, which is used by the 0.1-0.5% of fertilizer total amount, and also discloses its preparation method, is actually made
In, fertilizer need to first spray animal and vegetable oil when wrapping up.
But above two anti hardening agent effect is undesirable, especially in the season of summer high temperature high humidity, actual effect
It is difficult to ensure that product is not hardened.Particle surface will go out powder and change colour after generally going through placement in 1-2 months, when product is stored
Bonding is generated because mutually squeezing, and then the phenomenon that false caking occurs, can not thoroughly solve the problems, such as that high tower product is hardened, especially
Be using inert material add the fertilizer anti hardening agent of animal and vegetable oil day-light saving time it is long there is also smelly situation, and produce
Raw extremely bad smell.
It is corresponding the reason is as follows that：High tower fertilizer is fusing urea（Or ammonium nitrate）Sprinkling pelleting system after solution is mixed with other raw materials
, hygroscopicity variation variation bigger with other handicraft products compared with, it is easier to moisture absorption, the reason is that fertilizer is also when fertilizer is stored up
The reaction of follow-up salt can occur, reaction product can be diffused into particle surface, because the fertiliser granulates surface of prior art package is formed
Film without elasticity, can mutually be squeezed between fertilizer when stockpiling, lead to particle deformation, cause to bond between salt and salt, build bridge and
Hardened, the phenomenon that forming false caking is generated, needs manually to pound packet, increases cost.In addition, needed in anti hardening agent using it is dynamic,
Vegetable oil is the anti-caking oil that raw material makes, and this anti-compaction oil is saturated fatty acid and unsaturated fatty acid, is easy in summer
Corruption is smelly, and generates extremely bad smell.

A, the cost of conditioner is higher, and by its formula, fertilizer anti-compaction cost is about 30 yuan/ton.
B, in summer high-temperature high humidity season, the wrap film formed using the fertilizer surface of this anti hardening agent package is easy molten
Change, causes fertilizer too sticky and cannot be handled by conventional method.
C, the preventing blocking effect of the conditioner is not fine, is susceptible to false hardened.
It is corresponding the reason is as follows that：
A, the Oppanol B100's that the mineral oil of selection is naphthenic process oils, viscous elastomer is German BASF acquisition is poly-
Isobutene, both cost of material are all very high.
B, the slack wax that the wax target solidification point of selection is 37-43 DEG C, fusing point are relatively low.
C, the viscous elastomer polyisobutene molecular weight of selection is excessively high, in the medium and temperature range described in it, gathers different
Butylene cannot be dissolved or be melted, using the solvent of other polyisobutene that can dissolve B100 because of its volatility, toxicity, not environmentally.
