Description
Technical field
The invention discloses a kind of preparation methods of fertilizer anticaking agent, belong to technical field of chemical fertilizer production.
Background technique
With the fast development of economy and urbanization, population increases, and demand of the people to crops is increasing, therefore
It is required that crops have higher yield to meet the growing ability demand of people.Chemical fertilizer is added as raising crop yield
A kind of mode, has had been to be concerned by more and more people.Granulated fertilizer is made in chemical fertilizer more, and granulated fertilizer can reduce the suction of fertilizer
It is moist, the pollution to environment is reduced, is also convenient for applying.
However, fertilizer all has caking phenomenon to some extent, its property and service performance will affect, agglomeration is not only broken up
The free-flowing of product, and using when generally require to carry out break process, so often the agglomeration of fertilizer whether
An important indicator as product quality.With the continuous improvement of market competition to increasingly sharpen with level of farming mechanization,
The anti-caking problem of fertilizer is more and more taken seriously.The agglomeration problems for solving fertilizer, in addition to 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 on the influential condition of agglomeration and property, if the chemical reaction of weighing area, critical phase are to wet
Degree etc..External factor refer to water content, granularity and the uniformity of fertilizer, package temperature and in transport, storage, use process it is right
Agglomerate influential factor, such as temperature, pressure, ambient humidity.There is also caking performance for fertilizer anti-caking agents traditional at present
The problem of capable of can not further increasing, therefore also need to study it.
Summary of the invention
The present invention solves the technical problem of: it can not further be mentioned for conventional fertilizers anticaking agent agglomeration preventing performance
High problem provides a kind of preparation method of fertilizer anticaking agent.
In order to solve the above-mentioned technical problem, the technical scheme adopted by the invention is that:
(1) according to parts by weight, it successively weighs: 100~120 parts of polyvinyl alcohol, 60~80 parts of gelatin, 300~450 parts of water, 30
~50 parts of glutaraldehyde water solutions and 10~30 parts of hydrochloric acid, polyvinyl alcohol is mixed with water, and heating stirring obtains poly-vinyl alcohol solution,
Poly-vinyl alcohol solution is cooled down, and the poly-vinyl alcohol solution after cooling is mixed with gelatin, and sequentially add hydrochloric acid and glutaraldehyde
Aqueous solution, after being stirred, filtering pulverizes and sieves, and washs, and vacuum drying obtains gel；
(2) gel is mixed with water 1:20~1:30 in mass ratio, and 0.3~0.5 times of gel quality of Pasteur's gemma bar is added
Bacterium and 0.10~0.12 times of gel quality of glucose adjust pH to 8.5~10.0, after being stirred, adjusting pH to 5.0~
6.0, after concentrated by rotary evaporation, filter, it is dry, obtain additive；
(3) urea is mixed with paraffin 1:3~1:5 in mass ratio, Freezing smashing obtains pretreatment paraffin, will pretreatment paraffin with
Calcium oxide 4:1~4:2 mixed grinding in mass ratio, obtains modified paraffin；
(4) according to parts by weight, it successively weighs: 30~40 parts of modified paraffin, 20~30 parts of additive, 8~15 parts of corruption
Acid and 5~10 parts of adhesive are grown, modified paraffin are mixed with additive, and humic acid and adhesive is added, after being stirred, very
Sky is dry, obtains fertilizer anticaking agent.
Step (3) described paraffin is the mineral wax mixture that carbon atom number is 22~28.
The partial size of step (3) described calcium oxide is 50 mesh.
Step (4) adhesive is any one in carragheen or Arabic gum, preferably Arabic gum.
The beneficial effects of the present invention are:
(1) additive is added when preparing fertilizer anticaking agent in the present invention, firstly, coagulating in additive containing sensitive to pH
Plastic structure can expand in product use process with the raising of external environment pH after being added in product, thus
The formation of crystal brige between barrier fertiliser granulates prevents molecule diffusion, reduction capillary from sticking, reduces intergranular cohesive force, in turn
The preventing blocking effect of product is turned up, secondly, contain bus bacillus in additive inside gel structure, it can be swollen in gel structure
When swollen in conjunction with external urea, to generate carbanion, and then and calcium ion precipitating is formed between fertiliser granulates, thus
Further increase the agglomeration preventing performance of product；
(2) modified paraffin is added when preparing fertilizer anticaking agent in the present invention, on the one hand, aerobic in modified paraffin surface adhesion
Change calcium, after being added in product, with the hygroscopic effect of fertiliser granulates, calcium oxide can be reacted with water generates calcium hydroxide, and releases
Amplification quantity heat, the calcium hydroxide of generation can provide alkaline environment for the expansion of additive, and with Pasteur's gemma in additive
The carbonic acid calcium ion that bacillus generates forms precipitating, so that the caking performance of product be made to improve, on the other hand, the heat of generation can promote
Make paraffin and the thawing of adhesive is added, to form protective film in fertiliser granulates surface, improves the agglomeration preventing performance of product, and
And with the thawing of paraffin, urea can be provided for Bacillus pasteurii, promote the formation of calcium carbonate.
