Description
Technical field
The present invention relates to a kind of preparation methods of diatom soil matrix anti-caking agent for fertilizer, belong to anticaking agent technology of preparing neck
Domain.
Background technology
Fertilizer caking refers to that chemical fertilizer granule is bonded together the phenomenon that forming block.Currently used chemical fertilizer, especially
High nutrient chemical fertilizer, generally can all lump.The variation of the case where fertilizer caking extensively generally can be divided into greatly 3 kinds very much：Slight caking, serious knot
Block and part are lumpd.The chemical fertilizer slightly to lump can be affranchised flow regime by slight vibration;Serious caking be whole bag or
Whole heap chemical fertilizer has formed a bulk when in bulk, and chemical fertilizer is difficult to break into pieces at this time；Part caking is that part chemical fertilizer has formed fritter, this
Kind caking is the most unfavorable to mechanical fertilization, because these fritters easily block nozzle and are not easy to be found.It can be seen that fertilizer caking
Serious inconvenience can be brought to chemical fertilizer transport, storage and fertilising, also just at the mark of measurement chemical fertilizer products quality whether fertilizer caking
One of standard.Fertilizer caking not only carrys out prodigious puzzlement to the storage of chemical fertilizer and conveyer belt, but also can influence fertilising operation and chemical fertilizer
Effect.
Inert powder is wrapped in chemical fertilizer granule surface in a manner of physical absorption, reduces the contact between chemical fertilizer granule, weakens
Chemical fertilizer plays the role of insulation blocking to the absorption of outside moisture and the volatilization of self component to chemical fertilizer.However, inert powder
It itself is easy to reunite and absorb water, uses it as anticaking agent merely, preventing blocking effect is poor and function and effect are not lasting.
Therefore, a kind of good dispersion is invented, is not absorbed water, the novel diatomite base that preventing blocking effect is good and action time is permanent
Anti-caking agent for fertilizer has positive meaning.
Invention content
Present invention mainly solves the technical issues of, for current inert powder class anti-caking agent for fertilizer itself be easy reunite simultaneously
And absorb water, anticaking agent, preventing blocking effect difference and the unabiding defect of function and effect are used it as merely, provide a kind of silicon
The preparation method of diatomaceous earth base anti-caking agent for fertilizer.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is：
A kind of preparation method of diatom soil matrix anti-caking agent for fertilizer, it is characterised in that specifically preparation process is：
（1）It is fitted into sonic oscillation instrument after the ethanol solution of diatomite and mass fraction 50% is mixed, oscillation dipping, dipping knot
It is filtered after beam, isolated dipping filter residue, freezes 3~5min with liquid nitrogen spraying immediately；
（2）It after waiting for above-mentioned spray refrigeration, is put into ball grinder, is 20 by ball material mass ratio:1 oxidation is added into ball grinder
Zirconium ball milling pearl crosses 200 mesh sieve after grinding 3~5h, and it is to pre-process diatomite powder to collect sieving powder, spare；
（3）It is fitted into stainless steel pallet after soybean oil and natto are mixed, then stainless steel pallet is put into greenhouse, stand acid
It loses, obtains rancid product；
（4）It is fitted into fermentation tank, is first stirred with stirring rod anti-after above-mentioned rancid product and spare pretreatment diatomite are mixed
After answering 2~3h, sealed fermenter, standing for fermentation obtains fermentate；
（5）It is fitted into high-temperature high-pressure reaction kettle after above-mentioned fermentate and ethylenediamine tetra-acetic acid are mixed, high-temperature high-voltage reaction；
（6）Wait for it is above-mentioned after reaction, take out reaction product filtering, isolated reaction filter cake rinses 3 repeatedly with absolute ethyl alcohol
It is put into baking oven after~5 times, discharges to get diatom soil matrix anti-caking agent for fertilizer after dry.
Step（1）Described in diatomite and mass fraction 50% ethanol solution mass ratio be 1:8, vibrate dipping
Frequency is 25~30kHz, and the time for vibrating dipping is 5~8h.
Step（3）Described in soybean oil and natto mass ratio be 10:1, the temperature in greenhouse is 35~45 DEG C, air phase
It is 60~70% to humidity, it is 10~15 days to stand the rancid time.
Step（4）Described in rancid product and to pre-process diatomaceous mass ratio be 5:1, the temperature of standing for fermentation is 25
~35 DEG C, the time of standing for fermentation is 7~9 days.
Step（5）Described in fermentate and ethylenediamine tetra-acetic acid mass ratio be 10:1, the pressure of high-temperature high-voltage reaction
Temperature for 2.5~3.0MPa, high-temperature high-voltage reaction is 220~250 DEG C, and the time of high-temperature high-voltage reaction is 3~5h.
Step（6）Described in drying temperature be 70~80 DEG C, drying time be 5~8h.
The beneficial effects of the invention are as follows：
Ultrasonic immersing is blended using inert powder diatomite as raw material, by itself and ethanol solution in the present invention, then cold with liquid nitrogen spraying
Freeze, after freezing ball mill grinding obtain pretreatment diatomite powder, will soybean oil and natto be blended after be put into the item of high temperature and humidity
It is mouldy rancid under part, then be sealed by fermentation after rancid product and pretreatment diatomite powder are mixed, finally by fermentate and EDTA
It is blended and carries out high-temperature high-voltage reaction, finally obtained diatom soil matrix anti-caking agent for fertilizer, the present invention is by ethanol solution to diatomite
Surface carries out hydroxylating modification, and crushes diatomite using the ice effect of splitting, and then vegetable oil and natto rich in mould are blended,
It is rancid under conditions of high temperature and humidity, the rancid product rich in acid, ester is generated, then rancid product and pretreatment diatomite are blended
Lipid degradation in product spoiled by rancid oil or fat is generated a large amount of free property ester groups using microorganism, and is introduced into diatom by fermentation
Native surface, while esterification occurs using the acid of rancid product and the hydroxyl on diatomite surface, to shield diatomite surface
Polar hydroxyl groups, greatly reduce the surface energy of diatomite particle so that diatomite particle is in stable dispersity, keeps away
Exempt from the agglomeration using process, the ester group introduced to diatomite surface in esterification and fermentation process can improve
Diatomaceous hydrophobicity compensates for the defect that traditional diatomite is easy moisture absorption, finally under the action of high temperature and pressure and EDTA,
So that the part metals ion removing on diatomite surface, into the organic phase of rancid product, to be produced on diatomite lattice
Raw hole, improves diatomaceous physics and chemism so that final anticaking agent obtained has more excellent anti-caking
Performance improves its anti-caking time limit, and anti-caking agent for fertilizer produced by the present invention has good dispersibility and hydrophobicity, can be persistently
It is uniformly coated on chemical fertilizer surface, hydrophobic film is formed on chemical fertilizer surface, physically better buffer action is played to chemical fertilizer, is had
Have broad application prospects.
