Description
Technical field
The present invention relates to field of fertilizer production, more particularly to a kind of aqueous fertiliser anticaking agent and preparation method thereof, especially
Suitable for the preparation and application of powdery or crystalloid anti-caking agent for fertilizer.
Background technology
Chemical fertilizer, its either powdery or granular, can lump and lose flowability in some conditions, form showing for lump
As the phenomenon is referred to as fertilizer caking.Fertilizer caking phenomenon generally occur chemical fertilizer storage, handling and transportation in.Chemical fertilizer
Caking is mainly between chemical fertilizer granule because caused by the factor such as exchange of moisture, salinity dissolving recrystallization, generation salt bridge, it is not only
The outward appearance of chemical fertilizer is influenceed, its service efficiency can be also reduced.Conventional anti-caking agent for fertilizer is oil-soluble anticaking agent, inertia at present
Powder anticaking agent, oil-bound distemper mixing anticaking agent and a small amount of aqueous fertiliser anticaking agent.For example, Chinese patent (CN
It is raw material 101298400A) to use paraffin, alkylamine, wire tray -80, mineral oil, is stirred 20~30 minutes at 70 DEG C~80 DEG C
And it is made a kind of paste oil-soluble anticaking agent.The technology is mainly wrapped up using hydrophobic materials such as paraffin in fertilizer surface, is formed
One layer of hydrophobic membrane, hinders to form salt bridge between fertiliser granulates, so as to play preventing blocking effect；Chinese patent (CN 101450878)
With talcum as primary raw material, then add that potassium feldspar, attapulgite are finely ground, surface is modified, mixing is matched somebody with somebody and is made a kind of powdery and prevents
Agglomeration agent.The technology is adsorbed by inorganic particle in fertilizer surface, directly contact between fertilizer is hindered, so as to prevent fertilizer knot
Block；Chinese patent (CN 101199921) is with Gemini quaternary ammonium salt, anion surfactant, nonionic surfactant, poly-
Compound and water uniformly mix, and are made a kind of aqueous fertiliser surfactant.The oriented attachment that the technology passes through surfactant, shape
Into one layer of hydrophobic membrane of densification, the directly contact between chemical fertilizer granule is hindered, and reach the purpose of anti-caking.
But above-mentioned oil-soluble anticaking agent and inertia powder anticaking agent only have certain preventing blocking effect to granular chemical fertilizer,
And powdery or crystallization chemical fertilizer are small because of its particle diameter, specific surface area is big, and fertilizer caking is serious, using the methods such as above-mentioned parcel oil-bound distemper without
Method reaches preferable preventing blocking effect, also, the chemical fertilizer of above-mentioned traditional oil, powder coating can be produced during production and use
Oil slick and floating dust, it is not degradable in natural conditions, thus result in environmental pollution；Meanwhile, with the development of Fertilizer Market, aqueous fertilizer
Expect that the demand of chemical fertilizer constantly increases, will be current fertilizer industry urgent need to solve the problem using the agent of aqueous fertiliser anti-caking.
Therefore, it is necessary to provide a kind of new anticaking agent and preparation method thereof, it does not receive fertilizer grain diameter influence, not only fits
For Common compound fertilizer, and good preventing blocking effect can also be reached to aqueous powdery or crystallization fertilizer, while making work
Skill is simple, low cost and environmental protection.
The content of the invention
For the defect that above-mentioned existing fertilizer anti-caking agents are present, the invention provides a kind of aqueous fertiliser anticaking agent and
Its preparation method, its preparation and application for being particularly suited for powdery or crystalloid anti-caking agent for fertilizer.With conventionally employed oil, powder bag
The method of film is compared, and its consumption is few, and more preferably, having properly settled powdery or crystalloid chemical fertilizer cannot use oil, powder bag to preventing blocking effect
Film carrys out the problem of anti-caking.Meanwhile, the process for producing of the anticaking agent is simple to operate, easy, pollution-free, is easy to industry
Metaplasia is produced.
The technical scheme that the present invention is proposed with regard to above-mentioned technical problem is as follows：
On the one hand, there is provided a kind of aqueous fertiliser anticaking agent, it includes water soluble polymer, surfactant, low-carbon alcohols
And water, each material by mass percentage, water soluble polymer：10-50%, surfactant：5-20%, low-carbon alcohols：10-
20% and water：10-75%.
Preferably, each material by mass percentage, water soluble polymer：20-30%, surfactant：10-15%,
Low-carbon alcohols：12-18% and water：40-50%.

The mixture of one or more in property fertilizer starch, aqueous fertiliser polyurethane.
Preferably, the surfactant is AEO, AEO carboxylic acid sodium, fatty alcohol
One or more mixed in sodium sulfonate of ethoxylated, disecoctylmaleate sodium sulfonate, sodium methylene bis-naphthalene sulfonate
Compound.
Preferably, the AEO, AEO carboxylic acid sodium, AEO sulphur
Sour sodium is straight chain type or branched chain type, and carbon number, between 8-18, ethylene oxide number is between 2-18.
Preferably, the low-carbon alcohols are the mixture of one or more in methyl alcohol, ethanol, isopropanol, normal propyl alcohol.
On the other hand, a kind of preparation method of above-mentioned aqueous fertiliser anticaking agent is also provided, it comprises the following steps：
S1, to the water that 10-75% by mass percentage is added in the reaction vessel with agitating device and heater,
And heated；
S2, temperature to be heated add the surfactant of 5-20% by mass percentage and by matter when reaching 35-40 DEG C
The low-carbon alcohols of amount percentages 10-20%, and lasting stirring and heating in adding procedure；
S3, temperature stabilization to be heated add the water soluble polymer of 10-50% by mass percentage at about 60 DEG C,
And continue stirring, until each component dissolves and disperses completely, the aqueous fertiliser anticaking agent to be thus obtained.
Technique effect acquired by technical scheme is as follows：
The anticaking agent that the present invention is produced by fertilizer grain diameter influence, is not applicable not only to Common compound fertilizer, and to powder
Shape or crystalloid fertilizer have good preventing blocking effect.Specifically, because the present invention uses hydrophilic water soluble polymer
Material spreads over fertilizer surface, thus lockable fertilizer surface free water molecule, reduce the activity of hydrone, hinder chemical fertilizer
The generation of " dissolution-crystallization " process between grain, so as to reach the purpose of chemical fertilizer anti-caking；Secondly, increased using surfactant
Plus aqueous fertiliser polymer substance is in the spreadability on chemical fertilizer surface；Simultaneously using low-carbon (LC) alcohol and water mainly as anti-caking agent carrier.
Compared with conventionally employed oil, the method for powder coating, the anticaking agent consumption in the present invention is few but better, and properly settles
Powdery or crystalloid chemical fertilizer cannot use oil, the problem of powder coating.
Meanwhile, the anticaking agent that the present invention is produced has extraordinary hydrophily, and the use of aqueous fertiliser is not influenceed, and
Process for producing is simple to operate, easy, is easy to industrialized production, will not also be made because producing oil slick and floating dust in production process
Into environmental pollution.
