Definitions
- the present invention relates to a leaching control type fertilizer with improved floatability and a method for producing the same. More particularly, the present invention relates to a leaching control type fertilizer which is short in spreading controlled type fertilizer, And a method for producing the same.
- coated fertilizer is coated with a special polymer resin such as acrylic resin, polyurethane, polyolefin resin or the like on the surface of a general fast-acting fertilizer.
- a fertilizer in which the fertilizer component is gradually eluted as needed during the entire growth period of the crop by controlling the dissolution rate of the fertilizer component by coating with a certain thickness. Since the coated granular fertilizer can keep ineffectiveness during the entire growing period of crops, it reduces the fertilization frequency and reduces fertilization labor, maximizes fertilizer utilization efficiency of crops, and reduces pollution of river and groundwater by fertilizer nutrition. It is regarded as the best fertilizer among the fertilizers. However, since the coating of the controllable type fertilizer is composed mostly of a resin lacking in hydrophilicity, there has been raised a problem that fertilizer floats on rainfall and irrigation on fertilization.
- a problem to be solved by the present invention is to provide a controlled-release fertilizer having improved floatability, which satisfies the controllability of elution and the productivity required of the controlled-release fertilizer as described above, It is on.
- a granular fertilizer core comprising: a granular fertilizer core; A coating layer (shell) formed on the surface of the granular fertilizer core and containing an olefin resin; And an additive which is deposited on the coating layer and comprises ethylene oxide-propylene oxide-ethylene oxide (E0-P0-E0) or propylene oxide-ethylene oxide-propylene oxide (P0-E0-P0) To a controlled release fertilizer.
- the present invention relates to a method for preparing a controlled release fertilizer having an additive comprising the tri-block copolymer.
- the fertilizer comprises a coating layer comprising an olefin resin in sequence on the granular fertilizer core surface and an additive adhering layer comprising an E0-P0-E0 or P0-E0-P0 tri-block copolymer.
- the fertilizer may be various known fertilizers, for example, urea or compound fertilizer.
- the above-mentioned resin of the refined pin is not limited to this, but may be a polyolefin or an olefin and an ethylene vinyl acetate copolymer.
- the polyolefin is a high density or low density polyethylene, polypropylene, ethylene- Propylene copolymer, polybutene, butene-ethylene copolymer, and butene-propylene copolymer.
- the ethylene vinyl acetate copolymer is a copolymer containing itelline and vinyl acetate, and the content and molecular weight of vinyl acetate are not particularly limited.
- the weight ratio of the covering layer containing the olefin resin to the weight of the fertilizer is 1 to 20% by weight, preferably 2 to 15% by weight based on the total weight of the fertilizer.
- the olefin-based resin is coated on the granular fertilizer core to form a shell to have a fertilizer form contained in the shell. (E0-P0-E0) or propylene oxide-ethylene oxide-propylene oxide (P0) on the surface of a fertilizer having a granular fertilizer core contained in a coating film containing such a reelfin- -E0-P0) tri-block copolymer is further coated.
- the weight average molecular weight of P0 corresponding to the minor group in the E0-P0-E0 or P0-E0-E0 tri-block copolymer is preferably 950 to 4000 and the HLB value is preferably 1 to 10. It is also preferable that E0 is contained in an amount of 5 to 50% by weight based on the weight of the entire triply block copolymer.
- a hydrophilic surfactant of HLB 6 to 16 or higher is attached or mixed on the surface of fertilizer to improve the floating property of the granular fertilizer.
- the E0-P0-E0 or P0-E0-E0 tri-block copolymer which is a surfactant used in the present invention, has a HLB value of 1 to 10, more preferably HLB 1 to 5,
- the molecular weight of PO is preferably from 950 to 4,000, more preferably from 1500 to 4000 as the weight average molecular weight.
- the weight ratio of the hydrophobic groups is comprised between 50 and 95% by weight, based on the weight of the total tri-block copolymer.
- the molecular weight of the hydrophilic group E0 is preferably from 50 to 2000 as the weight average molecular weight, and the weight ratio of the hydrophilic group is preferably from 5 to 50% by weight based on the weight of the entire tri-block copolymer. If the length of the water shortener is too short, the adhesive strength to the surface of the fertilizer is not good and it is not suitable for short-time mixing. If the length is too long, the affinity with water will be reduced.
- the hydrophilic group when contained in the weight range as described above, it is confirmed that it adheres to the surface of the fertilizer very effectively even for a short period of slight mixing. If the weight ratio of E0, which is a hydrophilic group, is more than 50% by weight, adhesion with hydrophobic surface of the fertilizer is somewhat weak. If it is less than 5% by weight, there is no effect of improving floatability. Therefore, a proper balance between the force to attach to the surface of the hydrophobic fertilizer and the hydrophilicity to prevent flotation is needed.
- the coating layer may further contain an inorganic powder in order to improve the floatability of a more efficient dissolution-controlled fertilizer.
- an inorganic powder may preferably be a hydrophilic inorganic powder having a hydroxyl group on its surface, more preferably precipitated silica.
- Sipernat 22S from Evonik was used.
- it is an inorganic powder having a specific surface area of 100 m 2 / g to 500 m 2 / g and a particle size of 1 to 500.
- the specific surface area of the inorganic powder is 100 m 2 / g or less, Since the exposed hydrophilic part is not stratified, the affinity with water is low and the effect of improving the flotation is poor. In case of 500 m 2 / g or more, the specific gravity is generally low, which is not suitable according to the difficulty in the process. If the particle size is less than 1 m, the fine powder is blown and the fairness is poor. If the particle size is larger than lOOiffli, it is difficult to adhere to the surface of the fertilizer.
- the amount of the inorganic powder to be added is preferably 0.01 wt% to 1 wt% with respect to the total weight of the dissolution-control fertilizer.
- the release-controlled fertilizer of the present invention is characterized in that a tri-block copolymer in the form of E0-P0-E0 or P0-E0-P0 and / or a liquid phase additive comprising the inorganic powder is adhered to the surface .
- the additive is a liquid, the mixing property is very good. Therefore, the additive can be uniformly adhered to the granular fertilizer by simple mixing, and the floating property can be remarkably improved.
- step ii) coating the first coating layer with an additive comprising ethylene oxide-propylene oxide-ethylene oxide (E0-P0-E0) or propylene oxide-ethylene oxide-propylene oxide (P0-E0- And a method for producing a controlled-release fertilizer.
- the steps i) and i i) may also be performed by a known coating method, but the present invention is not limited thereto.
- the additive used in step < RTI ID 0.0 >#) < / RTI >
- a dissolution-controlled fertilizer improved in flotation problem in a short period of time can be prepared even by a mixing method such as a conventional simple ball mill (bal l mi 1 1).
- a mixing method such as a conventional simple ball mill (bal l mi 1 1).
- the leaching control type fertilizer according to the present invention excellently improves the floatability problem which is a problem in the conventional leaching control type fertilizer, thereby preventing float on the water surface after fertilization and remarkably reducing the generation amount of dust.
- Controlled release fertilizer was prepared by using additives and inorganic powders corresponding to the conditions shown in Table 1 below in order to confirm flotation depending on the composition of the dissolution-controlled fertilizer.
- Example Pluronic liquid 0.025 10 4,000 2 Si per 190 0.1 0 0
- the flotation rate was measured. Specifically, about 300 of the coated fertilizers were spread out so as not to overlap the 600 ml beaker, and then 50 ml was slowly poured along the wall of the beaker. The floating rate was calculated as a percentage of the number of particles floating on the water surface after the main water stream compared to the total number of particles. If the rate of injury is less than 100% The calculated rate of injury is shown in Table 1. Specifically, the flotation properties of Examples 1 to 13 and Comparative Examples 1 to 3 were verified as follows.
- Examples 1 to 7 are additives in which the ratio of E0 which is a hydrophilic group is 5 to 50% by weight and the molecular weight of a hydrophilic group is 950 or more and 4,000 or less and HLB is 1 or more and 10 or less. When 0.5% by weight of the additive was added, the effect of improving flotation was confirmed.
- Example 4 In Example 4, the E0 ratio was 10% and the HLB was 3 as low as in Examples 1 and 2, but the effect of improving the flotation was low. It is considered that the additive is not adhered to the surface of the granular fertilizer by a short time weak mixing applied in this experiment because the molecular weight of the hydrophobic group is relatively small. Therefore, it is most preferable when the molecular weight of the hydrophobic group is 1,500 or more and 4,000 or less .
- the amount of the additive to be added is preferably in the range of 0.025 wt% to 0.5 wt% with respect to the weight of the fertilizer.
- Examples 12 and 13 were prepared by adding inorganic powder and a surfactant together When the amount of the surfactant was 0.025 wt%, it was found that the floating property was further improved when 0.1 wt% of the inorganic powder was added to the surfactant alone.
- Comparative Examples 2 to 4 in which the properties were solid, were poor in mixing property and were not evenly adhered to the granular fertilizer by only rolling mixing at 60 rpm for 1 minute. As a result, when the additive was added in an amount of 0.5 wt%, the flotation rate of the fertilizer was 100% and the flotation was not improved at all.
