Description
Technical field
The invention discloses a kind of preparation method of slow-release anti-caking granulated fertilizer, belongs to agrochemical technology of preparing neck
Domain.
Background technology
With economy and the fast development of urbanization, population increases, and people are increasing to the demand of crops, therefore
It is required that crops have higher yield to meet the growing ability demand of people.Chemical fertilizer is added to be used as raising farming produce
A kind of mode of amount, has had been to be concerned by more and more people.Granulated fertilizer is made in chemical fertilizer more, and granulated fertilizer can reduce fertilizer
Hygroscopicity, reduce the pollution to environment, also allow for applying.
However, fertilizer can influence its property and performance, caking is not only broken up all to some extent there are caking phenomenon
The free-flowing of product, and using when generally require to carry out break process, so often the caking of fertilizer whether
An important indicator as product quality.With the continuous improvement to increasingly sharpen with level of farming mechanization of market competition,
The anti-caking problem of fertilizer is more and more taken seriously.The agglomeration problems of fertilizer are solved, except controlling suitable manufacturing condition
Outside, using anticaking agent and solution to this problem.The influence factor of fertilizer agglomeration can be divided into internal factor and outside
Factor.Internal factor refers to fertilizer itself to caking influential condition and property, and the chemical reaction, critical phase such as weighing area are to wet
Degree etc..External factor refer to water content, granularity and the uniformity of fertilizer, package temperature and during transport, storage, use it is right
Lump influential factor, such as temperature, pressure, ambient humidity.
In addition, in use, the utilization rate of nutrient is low in fertilizer for chemical fertilizer, is easily lost in, this not only brings huge
Big waste, and nutrient loss can cause water resource pollution into river, lake, and the material retained in soil can also change
Become soil constituent, deteriorate soil property, therefore, the utilization rate for improving chemical fertilizer has become a top priority.In order to reduce the leaching of fertilizer
Loss and the pollution to soil property, the rate of release for reducing quick-acting fertilizer nutrient is a kind of effective measures, so that crops can
Preferably absorb and utilize, the slow release for improving fertilizer is very urgent.
Therefore, the shortcomings that how improving the easy caking of conventional particles fertilizer and poor slow release, to obtain more high combination property
Granulated fertilizer, is that it is promoted and is applied to broader field, meets industrial production demand urgent problem to be solved.
The content of the invention
The present invention solves the technical problem of：The shortcomings that for conventional particles fertilizer easily caking and slow release is poor, carries
A kind of preparation method of slow-release anti-caking granulated fertilizer is supplied.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is：
（1）By micaceous rock 4~8h of ball milling, sieving, obtains mica powder, counts in parts by weight, takes 40~50 parts of granular ureas successively, and 8
~10 parts of mica powders, 10~12 parts of polyallylamines, 120~150 parts of organic solvents, first stir polyallylamine and organic solvent mixed
After closing 10~40min, granular urea and mica powder are added, under stirring, is continually fed into carbon dioxide, then pass through
Filter, obtains pre-treated particles urea；
（2）Count in parts by weight, take 40~60 parts of chicken feathers successively, 40~50 parts of water, 3~5 portions of sucrose, after constant temperature is stirred,
The bacillus licheniformis of chicken feather quality 4~6% is added, after constant temperature stirring is fermented 7~10 days, sterilizes, filters, concentration, obtains feather
Hydrolyzate；
（3）Count in parts by weight, take 30~40 parts of phosphatide successively, 2~4 parts of chitosans, 10~15 parts of mucoproteins, 150~200 parts
Water, ultrasonic disperse, obtains dispersion liquid；
（4）Count in parts by weight, take 20~30 parts of feather hydrolysis liquid, 60~80 parts of dispersion liquids successively, constant temperature is stirred, obtains into
Film liquid；
（5）Count in parts by weight, take 30~50 parts successively into film liquid, 100~150 parts pre-process urea granules, in fluid bed,
Pretreatment urea granules surface will be coated on after film forming liquid mist, it is dry, up to slow-release anti-caking granulated fertilizer.
Step（1）The granular urea average grain diameter is 1~3mm.
Step（1）It is 1 in mass ratio by C8 alcohol and 1-Methyl-2-Pyrrolidone that the organic solvent, which is,：1~1：3 mixing
Form.
Step（3）The phosphatide is any one in soybean lecithin or egg yolk lecithin.
Step（3）The mucoprotein is any one in Swine serum mucoprotein or avian ovomucoid.
The beneficial effects of the invention are as follows：
（1）Polyallylamine is dissolved in organic solvent by technical solution of the present invention first, adds granular urea, in carbon dioxide
Under effect, make to be formed on urea granules surface in the surface-crosslinked absorption film-forming of urea granules after polyallylamine absorbing carbon dioxide
Block water film, and mica powder is fixed in the film cross-linked network that blocks water, and avoids during following process, and urea is by into water in film liquid
Dissolving；
（2）Technical solution of the present invention using mechanical ball mill be micaceous rock dissociation, new explanation from mica powder surface and phospholipid molecule band
There is negative electrical charge, Electrostatic Absorption can be produced with the hydrophobic side of positively charged in the mucoprotein of addition, and in pre-treated particles urea surface
The parental type membrane formed with phosphatide, mucoprotein, chitosan and feather hydrolysis albumen is formed, during fertilizer storage, parents
The presence of mucoprotein and phosphatide in type membrane, can effectively improve the greasy property of fertilizer, so that fertilizer mobility is improved, furthermore,
The presence of parental type membrane, the carbon dioxide that can slowly discharge polyallylamine are deposited between membrane and granular urea, every
Carbon dioxide layer is formed between film and granular urea, avoids moisture from being contacted with internal particle urea, after fertilizer application, with
The degraded of parental type membrane, the release of inner silica carbon gas blanket, makes urea discharge into soil and is absorbed by plant, and
After carbon dioxide release, surrounding plants gas concentration lwevel can be improved, promotes photosynthesis of plant, furthermore, the present invention is using former
Material can further improve the fertilizer efficiency of urea containing the necessary element of the plants such as nitrogen phosphate and sulfur.
