Abstract
The invention belongs to the field of fertilizers, and provides a fertilizer after-treating agent, which is mainly characterized in that certain parts by weight of catering waste oil, hydrogen peroxide, phosphoric acid, hydrogen and the like are adopted, wherein the catering waste oil is subjected to oxidization, incomplete acidification, dehydration, hydrogenation and cooling. When the fertilizer after-treating agent is used, the dissolved solution of the fertilizer after-treating agent is sprayed to the surface of granulated fertilizer. The treated fertilizer has long storage period, does not block, has a slow release effect after application, can be degraded and has no toxic or side effect, a new approach is discovered for turning the catering waste oil into benefit and resource development, the harm caused to environment and food and drug safety is reduced, and the fertilizer after-treating agent has obvious technical advancement and socioeconomic performance.
Description
Technical field
The invention belongs to fertilizer field, relate to fertilizer additive, specifically propose a kind of chemical fertilizer post-treatment agent, the preparation method of this chemical fertilizer post-treatment agent is also provided.
Background technology
China Shi Yige large agricultural country, the consumption of various fertilizer is very large, and fertilizer is being used and in storage process, is easily hardening into piece, causes and uses inconvenient and waste.
Existing fertilizer prevents from hardening into piece technology and mainly contains: 1. in fertiliser production process, directly add SURFACTANT ADSORPTION in the surface of particle, form isolation waterproof layer, prevent the connection between particle; 2. after granulation, spray the organic compound (as paraffin etc.) of liquid, make it to be adsorbed in the surface of particle, solid surface is wrapped up and form isolation waterproof layer, prevent the connection between particle; 3. take atlapulgite, diatomite, talcum powder is raw material, interpolation paraffin, tensio-active agent and water-retaining agent etc. are pulverized the technique of grinding by blend and are made anti hardening agent, after granulation of fertilizer, add, anti hardening agent is adsorbed on fertiliser granulates and forms isolation, prevents hardening of fertilizer; 4. utilize the spray fertiliser granulates such as petroleum chemicals blending amine sheet (stearylamine), sulfonamides such as used oil or kerosene, diesel oil, the discarded chlorinated hydrocarbon of chemical industry or olefines or aromatic hydrocarbon solvent, to reach the effect that prevents fertilizer agglomeration.These methods have been alleviated the trend that fertilizer hardens to a certain extent, but exist the anti-caking time only for two weeks (firmly luming 5%), a month firm caking 10%, the petroleum chemicals such as paraffin, the stearylamine problem such as do not degrade.
On the other hand, China is populous, and the discarded oil mass of food and drink is large, discarded after stain environment, and even someone processes sewer oil, illegally for food and medicine, serious threat food and drug safety.Develop food and drink abendoned oil (sewer oil), turn bane into boon, turning waste into wealth is a very important problem.
Summary of the invention
Contriver is in being engaged in for many years the activity of chemical research, find that existing chemical fertilizer exists the problem that easy caking and existing fertilizer preventing blocking technology exist, through research and probe, object is to provide a kind of chemical fertilizer post-treatment agent and preparation method thereof, can utilize food and drink abendoned oil to make raw material, preparation cost is low, easy to use, preventing blocking effect is better, overcomes the problem that prior art exists.
The technical solution used in the present invention is a kind of chemical fertilizer post-treatment agent of development, adopts following weight part raw material to make: food and drink abendoned oil 70-95, hydrogen peroxide 1-5, phosphoric acid 0.5-1.5, hydrogen 0.5-2.
Chemical fertilizer post-treatment agent of the present invention adopts following processing method preparation: food and drink abendoned oil-oxidation-incomplete acidifying-dehydration-hydrogenation-cooling-finished product.
Wherein, food and drink abendoned oil, will collect discarded life with oily assorted through dewatering, another name sewer oil;
Hydrogen peroxide (or clorox, benzoyl peroxide etc.) is made oxygenant, in oxidising process, food and drink abendoned oil is played to sterilization, sterilization, deodorization;
Phosphoric acid (or sulfuric acid) is made souring agent, in incomplete acidization, makes the acidifying of part food and drink abendoned oil generate lipid acid, is used for being seeped into chemical fertilizer top layer, increases the combination degree that adheres on discarded food and drink oil and chemical fertilizer surface, forms waterproof layer, prevents that chemical fertilizer from hardening;
Hydrogen, catalyzer adds after dehydration, plays hydro-reduction effect, makes the resistance to storage of finished product, never degenerates, and after use, under certain outside temperature, changes form, plays the effect of alleviating fertilizer efficiency.
Through adopting described processing method, the finished product of the present invention of preparation is unformed wax.
During use, unformed wax-like finished product of the present invention is no less than to 1 kilogram of amount by chemical fertilizer per ton and controls, heat 70 ℃ and dissolve into above liquid, spray, in pending chemical fertilizer after granulation, mixes, and chemical fertilizer surface presents lubricated light, stop spray, realize the aftertreatment to chemical fertilizer.
Chemical fertilizer through processing with chemical fertilizer post-treatment agent of the present invention, extended pot life (reaching half a year), can more effectively prevent adhesion caking between fertilizer, after using, can play fertilizer efficiency slow release effect, formed waterproof layer is biodegradable material, have no side effect, can not produce pollution after entering soil or crop.
The present invention is not only for food and drink abendoned oil turns bane into boon, resource utilization develops and has found a new way, reduce the harm that environment is caused food and drug safety, and overcome the defect of prior art, there are Important Techmical Progress and significant economic results in society.
