Abstract
The invention discloses a preparation method of a naturally-degradable compound fertilizer anti-blocking agent and an application thereof. The naturally-degradable compound fertilizer anti-blocking agent comprises the following components in percentage by mass: 10-20 percent of fatty amine or salt thereof, 20-25 percent of stearic acid, 15-20 percent of oleic acid, 5-15 percent of refined glycerin and 20-50 percent of waste edible oil and fat, and the sum of all the components is 100 percent according to the percentage. The preparation method comprises the following steps of: mixing all the components according to the proportion, heating to be 70 DEG C -85 DEG C, and stirring and reacting for 15 minutes-30 minutes. The used amount of the compound fertilizer anti-blocking agent is 05-2.0kg/t (compound fertilizer), and a granulation mode of a high air-cooling crystallization tower of an all-molten compound fertilizer is adopted to mix the naturally-degradable compound fertilizer anti-blocking agent with the compound fertilizer. In the preparation method and the application thereof, the processing is simple, the use cost is low, the anti-blocking performance is good, the purely natural and environmentally-friendly performances are achieved, the absorption of crops is convenient, the fertilizer effect is enhanced, and the soil is protected.
Description
Technical field
The present invention relates to the preventing blocking technology field of composite fertilizer, refer in particular to a kind of preparation method and application of natural degradable compound fertilizer anticaking agent.
Background technology
The agglomeration problems of composite fertilizer more and more is subjected to the attention of manufacturing enterprise, most of fertiliser production enterprise all gropes the mechanism of granulated fertilizer caking and reason and inquires into, and taked different preventing block methods to alleviate the caking of fertilizer, to guarantee the free-running property of granulated fertilizer.
Existing anti-hard caking agent has three kinds on powder-type, aqueous solution type and oily molten type: 1, the powder-type anti-hard caking agent is to utilize inert powder to intercept the formation of brilliant bridge between fertiliser granulates, but need spray into oily matter simultaneously to adhere to inert powder when using.Though this method has the anti-caking effect, complex process, cost are higher, and the fertilizer dust is increased.2, the aqueous solution type anti-hard caking agent then be with surfactant dissolves in water, be sprayed at the fertilizer surface, to reach the effect that reduces the capillary purpose of fertilizer and play anti-caking.The shortcoming of this method is to have brought moisture into, and moisture is the immediate cause of fertilizer agglomeration.3, Oil solvent type anti-hard caking agent has been avoided the shortcoming of above-mentioned two kinds of methods, has easy to use, effective advantage, but traditional method need add mineral oil (as machine oil) as solvent, and the large usage quantity of mineral oil, be generally 4～5 times of anti-hard caking agent, the consumption of composite fertilizer per ton mineral oil in fluid reaches 2～3kg, and these mineral oil enter soil with fertilizer and are difficult to degraded, have caused pollution to a certain degree to soil and surrounding enviroment.
Summary of the invention
For solving the deficiency that exists in the above-mentioned technology, the invention provides a kind of process simple, use cost is low, anti-caking performance good, pure natural environment protection, be convenient to crop absorption, strengthen fertilizer efficiency, the preparation method and the application of the natural degradable compound fertilizer anticaking agent of protection soil.
The preparation method of this natural degradable compound fertilizer anticaking agent of the present invention, its component comprise aliphatic amide or its salt, stearic acid, oleic acid, refining glycerine, discard food oils, and it is characterized in that: each component is pressed following per-cent proportioning:
Aliphatic amide or its salt: 10～20%,
Stearic acid: 20～25%,
Oleic acid: 15～20%,
Refining glycerine: 5～15%,
Discarded food oils: 20～50%,
Above-mentioned each component sum is 100%; And each component is mixed in proportion, be heated to 70～85 ℃, stirring reaction 15～30min.
Described aliphatic amide is to be raw material with discarded food oils, makes corps acid after hydrolysis, distillation, and corps acid makes through ammonification system nitrile, repeated hydrogenation.
Described aliphatic amide is that carbonatoms is one of 8-24 fat primary amine or fatty primary secondary amine or its mixing; Described fatty amine salt is an aliphatic amine acetic acid salt.
Described stearic acid, oleic acid, refining glycerine make through rectifying separation for discarded food oils hydrolyzed product.
Described discarded food oils are sewer oil, swill oil, the old oil of frying, animal-plant oil tankage, acidifying oil one or more mixtures wherein.
The application of this natural degradable compound fertilizer anticaking agent of the present invention is characterized in that: the compound fertilizer anticaking agent consumption is 0.5～2.0kg/t composite fertilizer, adopts the wind-cooling crystallization high tower prilling mode of full-fusing composite fertilizer to make it to mix with composite fertilizer.
The preparation method of this natural degradable compound fertilizer anticaking agent provided by the invention and application can more effectively prevent compound fertilizer from caking, have the effect that improves granule strength, suppresses dust, and the outward appearance granularity that makes complex fertilizer product more evenly, slickness better, richer glossiness.Derive from the natural animal-plant grease again, belong to the novel environment friendly product, solved and used the problem of mineral oil in the past as solvent contamination soil.
