Abstract
The invention discloses a compound fertilizer antiblocking agent which comprises the following components in percentage by mass: 40.0-70.0% of vegetable oil, 10.0-30.0% of paraffin, 1.0-10.0% of octadecylamine, 1.0-10.0% of vinyl acetate, 1.0-10.0% of surfactant and 0.02-0.20% of benzoperoxide. After being mixed with a compound fertilizer, the compound fertilizer antiblocking agent can form a compound film with higher moisture and water resistance than the existing antiblocking agent on the compound fertilizer; and the film can effectively prevent ambient moisture from invasion, thereby preventing the compound fertilizer granules from mutual binding and agglomeration. Besides, the mixed compound fertilizer has obviously higher slow-release property, thereby finally, enhancing the fertilizer efficiency of the compound fertilizer. The invention also discloses a preparation method of the compound fertilizer antiblocking agent and an application method of the compound fertilizer antiblocking agent.
Description
Technical field
The invention belongs to composite fertilizer's anti-caking processing technology field, more particularly, to a kind of compound fertilizer anticaking agent and its system
Standby, using method.
Background technology
Composite fertilizer is affected to tend to lump by environmental factors such as moisture, temperature, accumulation pressure, and this is not only not easy to multiple
The storage in Hefei and transport, more cause greatly to perplex to fertilising.Thus, whether composite fertilizer can effectively prevent caking from having become for people
Evaluate an important indicator of fertilizer quality.
Existing compound fertilizer anticaking agent has powder-type, aqueous solution type and three kinds of oil soluble type：1st, powder-type anticaking agent is profit
Intercept the formation of crystal brige between fertiliser granulates with inert powder, but using when need to spray into oily matter simultaneously adhere to inert powder.
Although the method has an anti-caking effect, complex process, relatively costly, so that fertilizer dust is increased.2nd, aqueous solution type anticaking agent
It is then that surfactant is dissolved in the water, is sprayed at fertilizer surface, played with reducing the purpose of fertilizer surface tension force
The effect of anti-caking.The shortcoming of the method is to have brought moisture into, and moisture is the immediate cause of fertilizer agglomeration.3rd, oil soluble formulation anti-caking
Block agent avoids the shortcoming of above two method, has the advantages that easy to use, effect is good, but conventional method need to add mineral oil
(as machine oil) is as solvent, and the large usage quantity of mineral oil, and the consumption of composite fertilizer per ton mineral oil in fluid reaches 2～3kg, these ore deposits
Thing oil enters soil with fertilizer and is difficult to degrade, and causes a certain degree of pollution to soil and surrounding enviroment.

Or its salt 10～20%, stearic acid 20～25%, oleic acid 15～20%, refined glycerine 5～15%, recycled wood materials 20～
50%, that each group is divided and be 100%.
CN104355819A discloses a kind of degradable compound fertilizer anticaking agent, its component include fatty amine or its salt,
Stearic acid, oleic acid, refined glycerine, recycled wood materials, that above-mentioned each group is divided and be 100%, wherein, each component presses row percentage
Compare proportioning：Fatty amine or its salt：5～15%, stearic acid：15～20%, oleic acid：10～14%, refined glycerine：5～15%, give up
Abandon edible oil and fat：20～50%.
Being summed up conventional surfactant type has：Anion surfactant, mainly has alkyl sulfate, alkylbenzene

Deng；Amphoteric surfactant etc..
But above-mentioned anticaking agent of the prior art, its moistureproof and waterproof function and conjunctiva ability still depend on
Aliphatic acid（Ester）And fat（Acyl）The film-formation result of amine is although other organic matters adding have certain hydrophobicity, but moistureproof
Waterproof whole structure is not satisfactory all the time.In addition, mixing the fertilizer of above-mentioned anticaking agent, the sustained release performance of fertilizer is not also very managed
Think.
Content of the invention
The technical problem to be solved is to overcome the shortcomings of to mention and defect in background above technology, provide one
Kind have that anti-caking performance is good, environmental protection；After mixing with fertilizer, the sustained release performance of fertilizer is significantly improved, is easy to fertilizer
The compound fertilizer anticaking agent that crops absorb.
In order to realize foregoing invention purpose, the invention provides a kind of compound fertilizer anticaking agent, by vegetable oil, paraffin, hard
