Description

FIELD OF THE INVENTION [0001] The present invention relates to a water-

The present invention relates to a water-in-oil type granule and a method for producing the same, and more particularly, to a water-based floating granule using oil absorption and particle size controlled micro-glass bubble and water- Which can be quickly diffused into the rice paddy in a floating state on the water surface when applied to a water-borne floating particle and a method for producing the same.

Formulations of pesticides used in sunscreens include granules, powders, emulsions, wetting agents, and liquid wetting agents. Among them, the granules and powders are advantageous in that they are easy to handle and work because they use a method of directly spraying the preparation without diluting the preparation in water.

However, if the treatment area is large, the granule must be loaded and sprayed directly with a large amount of medicines. Therefore, the load of the labor force due to the weight is large, but the labor force is severely shortened due to the recent decline in farm labor force and aging. It is imperative that the introduction of the grain can be done.

Korean Patent Laid-Open No. 2009-0130583 discloses a floating agent for pesticide floating on the surface of a poultry, and discloses a poultice capable of uniformly spreading the pesticide base agent uniformly while floatping automatically when thrown on a paddy field. However, the above-mentioned patent discloses that potassium hydrogen carbonate is used to float the granular material to float the surface of the granular material. However, there is a merit that the agricultural chemical raw material can spread far along with the generation of carbonic acid gas. However, It can be a problem, and the granules can be buried in the rice field with strong foaming. In addition, there were a number of techniques in which a medicament was carried on a suspending agent having a floating nature so that the medicament spreads naturally on the surface of the water. Korean Patent No. 10-0843332 increases the spraying distance by reducing the size of the granules to a grain size, but does not increase the spreading property, and thus there is a limit to the evenly spreading of the medicines in a short period of time.

Korea Patent Publication No. 2009-0130583 Korean Patent No. 10-0843332

Accordingly, it is a first object of the present invention to solve the above problems, and it is an object of the present invention to provide a floating surface-type tablet that can be rapidly diffused into the rice paddy in a state floating on the water surface when applied to non-nonson.

A second object of the present invention is to provide a method for producing the float-surfaced granular material for improving the diffusibility of the agricultural chemical agent suspended in the water surface.

However, the problems to be solved by the present invention are not limited to the above-mentioned problems, and other problems not mentioned can be clearly understood by those skilled in the art from the following description.

The agrochemical raw material is preferably water insoluble, but it is not limited thereto.

In one embodiment of the present invention, the agrochemical raw material may be included in the water-based floating granular material at about 0.5 to about 40 parts by weight, and preferably about 5 to about 20 parts by weight. The surface-lifting type granule of the present invention can exhibit high efficacy by increasing the surface area and reducing the content of the agricultural chemicals.

The micro-glass bubbles may be prepared by foaming sodium silicate and borax, and the ratio of water to water may be about 95% by weight to about 99.9% by weight based on the total weight of the micro-glass bubble. Glass bubbles are widely used for water surface pesticides, but in the present invention, micro-sized glass bubbles are used and the absorption of micro-glass bubbles (about 20 g / 100 cc to about 50 g / 100 cc or about 30 g / 100 cc to about 40 g / 100 cc) and particle size (from about 15 탆 to about 60 탆 or from about 20 탆 to about 40 탆).

The absorption value of the micro-glass bubble is preferably 20 g / 100 cc to 50 g / 100 cc or 30 g / 100 cc to 40 g / 100 cc. If the microgas bubble absorbency value is less than 20 g / 100, the viscosity of the water-in-oil type granules becomes very low when the raw material, binder, water-spreading agent is liquid or further water is added, And when the microbubble absorption rate of the microbubble is more than 50g / 100cc, the water-absorbing performance is excessively strong, so that the water-floating particles are not formed into a solid tablet, but formed into a powder form Or formed in the form of a solid tablet, the strength is low and can easily be broken.

The micro glass bubbles, a density of about 0.1 g / cm ³ to about preferably about 0.5 g / cm ³ and, due to the micro-glass bubble-type surface portion granules of the present invention is able to float on the surface. The micro-glass bubbles are brought into contact with water in the granule and carry the pesticide agent from the innocent to the corner while the collapsed particles spread out.

The micro-glass bubbles may be included in the water-in-oil type granules in an amount of about 10 parts by weight to about 40 parts by weight, and preferably about 20 parts by weight to about 30 parts by weight.

The function of the sleeping spreader, which is included in the sleeping-type granules of the present invention, is to disperse the granules widely at the surface of the water. This function means a very aggressive mobility activity (so-called dancer action) to automatically spread widely the pesticide base at the surface of the water. In addition, the water-borne propagating agent has a repulsive force between the collapsed particles in contact with water at the water surface, thereby causing the particles to push each other out. As the sleep accelerator, an alkoxylated active hydrogen compound, that is, an alcohol compound may be used. The waterproofing agent may be included in the water-in-oil type granulation agent in an amount of about 2 parts by weight to about 15 parts by weight, and preferably about 5 parts by weight to about 10 parts by weight.

Examples of the active hydrogen compound include ethylene glycol, diethylene glycol, triethylene glycol, polyethylene glycol (Mw is less than 1,000), glycerin, diglycerin, polyglycerin (Mw is less than 1000) having 1 to 12 carbon atoms, , Carbitols, trimethylol propane, pentaerythritol, sorbitols, alcohols, alkynols, alkenols, alkanediols, alkenediols, alkanediols, alkanetriols, fatty alcohols, fatty acids, phenols, alkylphenols, benzyl alcohols , Alkylbenzyl alcohols, alkanolamines (monoethanolamines, diethanolamines, triethanolamines), alkylamines (alkyl groups having 4 to 12 carbon atoms), polyalkylene polyamines (Mw less than 500, , Pentaerythritol hexaamine), and polyethylene polyimines, but is not limited thereto.

The waterproofing agent may include a polyoxyethylene alkyl ether compound. For example, the polyoxyethylene alkyl ether compound may be a polyoxyethylene alkyl ether, a polyoxyethylene polyoxypropylene alkyl But may include polyoxyethylene polyoxypropylene alkyl ether, polyoxyethylene polyoxypropylene alkyne ether, butyl cellosolve, and polyoxyethylene alkanediol ether, But may not be limited.

Preferably, ethylene oxide ( EO ), propylene oxide ( PO ) and butylene oxide ( BO ) are used as raw materials for the alkoxylation of the active polyhydrogen compound. In the alkoxylation reaction, the molecular ratio of EO , PO and BO can be flexibly adjusted, but at least EO must be present. The HLB (hydrophile-lipophile balance) of the alkoxylated active hydrogen compound formed by the alkoxylation reaction may be 2 to 14, preferably 3 to 12. The equation for calculating HLB is:

( PO and / or BO is a hydrophobic group)

The water-in-oil type granule of the present invention contains micro-glass bubbles together with a water-insoluble growth promoting agent, thereby exhibiting aggressive migration activity, in which the granules are spread very violently, such as dancing on the surface of water. Accordingly, even if the water-floating type granules are thrown to the silkworms in the rice paddy, the silkworms can automatically spread on the surface of the silkworms while spreading wildly to the rice paddies, thereby uniformly distributing the pesticide raw materials over the silkworms.

The water-soluble extenders, which are included in the water-in-oil type granules of the present invention, are water-soluble fillers that are well soluble in water or are well dispersed in water, and function to easily disintegrate the water-in- The water soluble extender may be a water soluble inorganic salt or a water soluble organic salt. The water-soluble inorganic salt is not particularly limited but may be one or two selected from the group consisting of NaCl, KCl, NH ₄ Cl, (NH ₄ ) ₂ SO ₃ , Na ₂ CO ₃ , K ₂ CO ₃ , Or more. The water-soluble organic material is not particularly limited, but sodium benzoate or sodium citrate or ethylenediaminetetraacetate inorganic salt may be mentioned. The water-swellable granule may comprise from about 10 parts by weight to about 85 parts by weight of the water-soluble extender, preferably from about 10 parts by weight to about 50 parts by weight, or from about 50 parts by weight to about 80 parts by weight have.

The water-swellable granules of the present invention may further comprise about 0.1 parts by weight to about 20 parts by weight of the water-insoluble extender. If the water-insoluble extenders are used in excess of 20 parts by weight, the water-insoluble extenders may cause a weakening phenomenon. In the present invention, since the amount of the water-insoluble thickener can be reduced by using micro-glass bubbles, it is preferable not to use more than 20 parts by weight. In addition, it is preferable that the water-swellable granule contains about 0.1 to about 5 parts by weight of the water-insoluble thickener.

The water-insoluble extenders may comprise white carbon having a specific surface area of from about 150 m ² / g to about 5000 m ² / g. The water-insoluble bulking agent plays a role of adsorbing the pesticide base agent, and when the pesticide base agent is adsorbed on the water-insoluble bulking agent containing particles having a large specific surface area, the efficacy of the pesticide can be exhibited with high efficiency even if the amount of the pesticide is reduced. The specific surface area of the water insoluble bulking agent is, for example, about 150 m ² / g to 5000 m ² / g, about 150 m ² / g to 4000 m ² / g, about 150 m ² / g to 3000 m ² / g, from about 150 m ² / g to 2000 m ² / g, about 150 m ² / g to 1000 m ² / g, about 150 m ² / g to 750 m ² / g, about 150 m ² / g to 500 m ² / g, about 150 m ² / g to 250 m ² / g, about 250 m ² / g to 5000 m ² / g, about 500 m ² / g to 5000 m ² / g, about 750 m ² / g to 5000 m ² / g, from about 1000 m ² / g to 5000 m ² / g, from about 2000 m ² / g to 5000 m ² / g, from about 3000 m ² / g to 5000 m ² / g, or from about 4000 m ² / g to 5,000 m < ² > / g.

The water-insoluble extenders may be prepared by mixing at least one member selected from the group consisting of clay, diatomite, bentonite, talc, diatomaceous earth, calcium carbonate, kaolin, kaolin, magnesium carbonate, carbon black, silica, zeolite, montmorillonite, Can be used.

The water-in-oil type granule of the present invention may further include at least one selected from the group consisting of a dispersant, a binder, and a disintegrating agent.

When the amount of the dispersing agent is about 1 part by weight to about 5 parts by weight, the agrochemical raw material or the extender is a specific gravity and has a property of sinking under water. This prevents the dispersant from sinking and allows the agrochemical agent to float in water for a long time. As the dispersing agent, an anionic surfactant or a nonionic surfactant may be used. Specifically, salts of naphthalenesulfonic acid formalin condensate salts or naphthalenesulfonic acid formal condensates, salts of naphthalenesulfonic acid or naphthalenesulfonic acid, alkyl Salts of benzenesulfonic acid or alkylbenzenesulfonic acid, salts of dodecylbenzenesulfonic acid or dodecylbenzenesulfonic acid, alkylsulfate salts, sodium dodecylsulfate, salts of lignosulfonic acid or lignosulfonic acid, and salts of polycarboxylic acids or poly Salts of carboxylic acids, and the like may be used, but the present invention is not limited thereto.

The binder serves to keep the shape of the water-floating granules after they are formed. The binder may be one or more selected from the group consisting of polyvinyl alcohol having a molecular weight of 1,000 to 20,000, polyvinyl pyrrolidone, carboxymethyl cellulose, polyacrylate or polyacrylate salt, cellulose, and polyoxyethylene oxide Can be used. The surfacing surfacing granulate may further comprise from about 1 part to about 5 parts by weight of the binder.

If the floating surface type granule is too hard, the pesticide base material will not spread to the whole paddy, but will stay locally and cause a weakening phenomenon. The disintegrating agent serves to wake up the form of the surficial floating granules. As the disintegrant, hydrophilic substances such as starch, starch, chitosan, sucrose, polycarboxylic acid, or polycarboxylic acid salt may be used. The water-swellable granule may further comprise about 0.1 to about 2 parts by weight of the disintegrant.

The oil-in-water type oiling composition of the present invention may further comprise an oil stream, and the oil stream may include cooking oil or mineral oil. The oil flow is preferably, but not always, used when the water-in-oil type granule includes a water-insoluble pesticide raw material. The oil flow prevents the pesticide agent from sinking under the water.

In addition, the present invention provides a method for producing a pesticidal composition, comprising the steps of: preparing an agricultural chemical mixture by mixing an agricultural chemical agent, a water-spreading agent and an extender, pulverizing the agricultural chemical composition to obtain a powder, and mixing the powder with a micro- The present invention provides a method for producing a surfacing floating granule.

The extender may be a water-soluble extender, a water-insoluble extender, or a mixture of a water-soluble extender and a water-insoluble extender.

The water-floating granule of the present invention can be shaped to have various shapes such as a ball shape, a disc shape, a plate shape having a polygonal front surface shape, a rod shape, a ground pod shape, and the like.

The second aspect of the present invention relates to a method for manufacturing a floating surface-type granular material, wherein a detailed description of parts overlapping with the first aspect of the present application is omitted, but the description of the first aspect of the present application is based on the second aspect The same description can be applied even if the description is omitted.

Hereinafter, the present invention will be described in more detail with reference to Examples. However, the following Examples are given for the purpose of helping understanding of the present invention, but the present invention is not limited to the following Examples.

Example  1 to 7

Experimental Example

The appearance, floatation rate, decay time, run-up speed, and run-away distance of the water-borne floating fabric prepared in the above Examples and Comparative Examples were measured and shown in Table 7 below.

Experimental Example  1-1: Appearance

The shape of the appearance was visually observed, and when the shape of the floating surface-type granule was in the form of a tablet, it was described as TB.

Experimental Example  1-2: Floating Rate and Decay Time

The floating rate was as follows: 200 mL of water was filled in a beaker, 0.2 g of each of the water-borne floating formulations prepared in the above-mentioned Examples and Comparative Examples was dropped, and after 1 minute, 2/3 or more of floating floating- The amount (g) was measured and the floating rate was calculated.

In addition, the time taken for completely disintegrating more than 95% of the 0.2 g of the floating flotation agent dropped on the water while measuring the floating rate was measured as the decay time. At this time, the collapse time is preferably about 2 to 8 minutes.

Experiment 1-3: Full speed , And Full distance

Water is poured into the measuring instrument shown in Fig. 1 at a temperature of about 25 deg. C at 3 degrees to fill 2/3 of the measuring instrument. Thereafter, 0.2 g of each of the water-based floating granules according to the above-described Examples and Comparative Examples was dropped at a distance of about 5 cm from the right end, and the water- We measured the time to measure the speed of penetration, and calculated the maximum distance by measuring the distance that the water surface floating particle moved farthest from the initial position of the measuring tool. At this time, the speed of the power is 10 ~ 40 s / 100cm, and the power distance is 1.70 ~ 2.00 m.

The results are shown in Table 7. Referring to Table 7, the water-in-oil type granules of Examples 1 to 20 prepared according to the present invention have a tablet form and have excellent floatation rate, as well as good collapse time, . On the other hand, all of the water-borne floating formulations of Comparative Examples 1 to 11 prepared in the composition ranges not shown in the present invention had no tablet form and had low floatation rate, and all of the collapse time, Which is significantly lower than that of the embodiment. The above contents will be described in more detail through the following results 1 to 3.

Result 1: Sleep-prone  Whether or not to use

Comparative Example 1 using only micro-glass bubbles was not sufficiently concentrated, and the shortest power-up distance was short and measurement of the power-on speed was impossible. However, Examples 1 to 7 using the micro-glass bubble and the water- It is 6 ~ 8 times longer, and it can be seen that the fastening speed is significantly faster.

In Comparative Example 1 using only micro-glass bubbles, the floatation rate was very low and the decay time was long. However, Examples 1 to 7, in which the micro-glass bubble and the water- And the collapse time is about twice as fast.

This means that the use of micro-glass bubbles and a sleeping-prone agent have higher floatation rates, better collapse times, faster speeds, and shorter reach distances than those used separately. If micro-glass bubbles are used together with water- It is considered that there is a synergistic effect on the performance of floating type granules.

Result 2: Micro Glass bubble  Difference by type

MGB 1 having an oil absorption of 30 g / 100 cc and a particle size of 40 탆 was used for the surfacing type granules of Examples 1 to 7, MGB 2 having a particle size of 50 탆 and 15 g / 100 cc for Comparative Example 2, Comparative Example 3 had MGB of 55 g / 100 cc and particle size of 50 m, MGB 4 of 30 g / 100 cc and 10 m of particle size in Comparative Example 4, 30 g / 100 cc of Comparative Example 5, MGB 5 having a thickness of 65 μm is used.

First, the surficial floating type granular material of Comparative Example 2, which has a lower oil absorption value than those of Examples 1 to 7, failed to form a tablet form and formed a viscous gel state like wax. In Comparative Example 3 Of the water-soluble granules formed a tablet form, but the strength was extremely weakened by excessive absorption.

In Comparative Example 4, which was smaller in particle size than Examples 1 to 7, tablet form was formed but Comparative Example 5 in which the floating rate was low, the disintegration time was long and the particle size was large, the tablet has a high floating rate, but the disintegration time is too fast, so that it can be seen that the breakthrough does not occur properly.

Result 3: Sleep-prone  Difference by type

In Examples 8 to 14, various types of waterproofing agents were used to prepare water-based floating granules.

It can be seen that all of the water-based floating granules of Examples 8 to 14 form tablets and have excellent floating rate. In addition, it can be seen that a slight difference is good in both the decay time, the full speed of energization, and the full-power distance.
