Description

A throwing effervescent agrochemical composition by use of urethane and manufacturing / using method

The present invention is a direct processing spray tablet that throws and diffuses from the paddy field without entering into the rice paddy, and processes several dozens in 10a (300 pyeong) in a short time can prevent the safety of workers, labor savings, and induction of weakness. The present invention relates to a viable foaming pesticide composition excellent in pest prevention effect and to a method of manufacturing and using the same.

Conventional sleep injury non-foamable tablet technology is disclosed in the Republic of Korea Patent Registration No. 100225878B1, Registration No. 10-084332 is a method of adsorbing the pesticide components to the pores by floating floating non-destructive porous carrier, but this is a pesticide Even after the components are eluted, the residue of the porous carrier remains, and the decay time and the diffusion time are delayed, and the pores of the carrier are pressed during tableting, and the pesticide component is released during manufacturing.

Japanese Patent Laid-Open No. 3-128301. 3-223203, 5-29903, and 11-222403 disclose methods for preparing suspended foam tablets using acid and alkali in general.However, in the disclosed method, carbon dioxide is generated by absorbing moisture during storage of the thrown tablet and causing self-reaction. Decreased foaming power has a disadvantage that the pesticide component is not evenly spread in the throwing place. In order to prevent this, there is disclosed a method of packaging with a film or putting a moisture absorbent together in a wrapping paper. However, there is an inconvenience in that the wrapping paper is damaged due to generation of gas due to moisture of the raw material itself. Korean Laid-Open Patent 2001-051677 discloses a formulation containing anhydrous ammonium alum as an inorganic acid as a conventional herbicide for effervescent water. In general, a method of preparing a floating throwing tablet pesticide preparation using a sustained-release expansion agent is described by adding an aqueous ammonium alum with low water solubility and reactivity, which is generally used in the food field, to suppress reaction with water. However, this patent also requires a drying process to remove the original moisture of raw materials and subsidiary materials, and it is possible to avoid the generation of gas during storage because the foaming function can be maintained by adding a conventional acid instead of solely anhydrous ammonium alum. . Korean Patent No. 10-0194112 discloses that a water-soluble block copolymer compound such as polypropylene glycol may be heated to coat the foaming component and the foaming period may be extended by using a water repellent such as magnesium stearate. The patent describes a method of heating a block copolymer to a certain temperature and mixing and cooling the raw materials and then molding or molding at a predetermined temperature and cooling to obtain a finished product, and a heating step or a cooling step should be introduced. Difficulties such as the release of gas due to lack of water-soluble block copolymer safety due to the rise of the external temperature during storage. Korean Patent Registration 10-2007-0067762 discloses a manufacturing method for storage safety by first coating polyethylene glycol (melting point 40 ~ 65 ℃) to a general blowing agent organic acid and a second coating with a moisture absorbent and a water repellent agent. This patent also applies a method of heating and mixing a primary coating material during manufacture, followed by mixing moisture absorption and release agents in a second manner, by heating and mixing polyoxyethylene glycol, which is a primary coating material, in a mass production process and proceeding with a secondary coating process. Since the melting point of the primary coating material according to the inconvenience of the heating process and the external storage temperature of the product, it is difficult to maintain the foamability and to block the moisture contained in the raw materials.

An object of the present invention relates to a solid pesticide composition that can be safely thrown in a method of reducing the labor force, and to a method for producing and using the same.

In other words, reducing contact time between pesticides and users, it promotes safety for workers, simplifies the usage of users, minimizes labor, does not use facility equipment, and is not diluted in containers. Can be processed uniformly.

Despite the simplicity and convenience of such direct treatment throwing tablets, their limited use is due to the limited use of pesticide active ingredients and the mechanism of action in freshwater paddy fields. This is because stability against the drug efficacy can be exhibited when the foaming capacity is maintained during treatment. In order to maintain effervescent properties, it is important to maintain physical and chemical safety so that materials used as raw materials in the prepared pesticide formulations do not cause magnetic reactions during mutual storage. We tried to solve the factor as follows.

The physicochemical technology to remove the contact reaction of acid alkali, the core of the technology,

1. A method of treating an organic acid coating and the surface of powdered sodium bicarbonate, which is representative alkali, with a moisture absorbing layer or the use of treated alkali;

2. Combined use of coated organic acid and anhydrous potassium alum and use of surface treated alkaline agent; And

3. As a lubricant, sodium stearyl fumarate with excellent water repellency and good dispersibility when dissolved in water is introduced during tableting, preventing mass production process and product dust, thus helping manufacturing workers and pesticide workers. Gives excellence

The composition of the pesticide selected to apply such a technique is composed of a pesticide active ingredient, a foaming component capable of generating a gas in water, a component capable of coating the foaming component, a surfactant, a lubricant and a dispersion and diffusion aid. In addition, there is an advantage that can proceed at room temperature without heating or cooling during organic acid coating operation for mass production. Here, the reaction of the urethane used for the coating method primarily follows the following formula (1).

Where R = toluene diisocyanate (TDI), diphenylmethane diisocyanate (MDI), 1.6-hexamethylene diisocyanenitite (HDI), 2,2,2trimethylhexamethylene diisocyanate (TMDI), para-phenylene Diisocyanate (PPDI) and the like,

 R '= ethylene glycol, propylene glycol, diethylene glycol, dipropylene glycol, glyserine, sorbitol, mannitol, sugar, etc.)

In other words, inject a citric anhydride into a mixer with a stirrer, add toluene diisocyanate (TDI) in the air as a weight ratio of 0.1 to 2 in the air, and add 0.1 to 0.5 propylene glycol while stirring to penetrate the surface of the organic acid. The controlled resin becomes the coating, to which the intermediate (A) is prepared by adding dextrin to the coated material. The carbonate used for alkali may be used as it is, and the carbonate which heated this carbonate at 100-150 degreeC for 10 minutes-2 hours, and formed the moisture absorption layer in the surface layer of carbonate can also be used. If this is expressed as a reaction formula, it is as following Formula (2).

That is, in the present invention, both of acid and alkali, which are the main components of the blowing agent, attempted a technique for blocking water and air, and in the existing prior art, coating the acid side only prevents unsafe moisture and self-pollution. It was intended to prevent the generation of gas by spontaneous reaction. Surfactant is added to the mixed powder (A, B) of the acid coated with urethane and the surface-treated alkali alone or in combination with pesticide insecticide, bactericidal and herbicidal components, and tableted by adding the lubricant immediately before molding. The lubricant is preferably added and mixed immediately before molding, and hydrophobic materials such as calcium stearate, magnesium stearate, and talc are preferred to hydrophilic properties such as polyethylene glycol, propylene glycol, and glycerin esters. Sodium stearyl fumarate used in the present invention has excellent advantages. General lubricants have low hardness with longer mixing times, whereas sodium stearyl fumarate does not.

Compared with magnesium stearylate, it is also effective because it has the same hardness, high decay time, short disintegration time, and low amount of foreign matter on tablet press after tableting, which is a problem in mass production.

The reaction rate may be further controlled by adding potassium anhydrous alum in a ratio of 10:10 to 50, preferably 10:25 to 35, as a mixed acid in the urethane-coated organic acid.

Anhydrous alum potassium is a carbonic acid gas expandable swelling agent that has been conventionally used in the baking industry.
