Description

Smoke agent using low-temperature unsalted smoking process and its manufacturing method

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fumigant using a low temperature flameless fumigating process having the functions of a disinfectant and a biocide for disinfecting pathogenic bacteria and controlling pests, and particularly, a method for preparing a smoker and a method for disinfecting and controlling space / surface. Smokeless agent and its manufacturing method using low-temperature salt-free fumigation process that can disperse and rescue all spaces of object by dispersing through the natural dispersion through the sublimation or vaporization of solid or solid products, not the spray method of liquid products. It is about.

As the plant cultivation area of various crops increases and the yield per unit area increases, the amount of pesticides used and the number of times of use are increasing. Moreover, since greenhouses are cultivated year round, greenhouses are kept at a constant temperature, so that the environment is very suitable for the breeding of pests.

Recently, winter cultivation of high-income crops has been activated, and the size and area of facility houses growing them are on the rise. The cultivation of winter crops is the most important control of temperature and humidity and can not be ventilated to maintain the temperature, the lack of ventilation causes an increase in humidity and damage of pathogens and pests due to over-humidity is a serious situation.

Pesticides sprayed in nearly closed facilities are heavily sprayed into the liquid phase due to the limited formulation form. Spreading these pesticides in the facility requires a long time, high risk of poisoning due to contact with or inhalation of the pesticide solution during the spreading process, and often leaves spots due to the pesticide solution on plants and fruits. There are several drawbacks, including the possibility of dropping, and most of the use of water, resulting in over-humidity, which may encourage the development of pests.

Spraying conventional liquid disinfectants and biocides with excess water for disinfection and control not only results in higher humidity, but also requires expensive spraying equipment or a lot of labor. Moreover, when spraying liquid disinfectant disinfectants or biocides with manpower, there may be a great concern for damage such as drug poisoning or humidifier accidents due to prolonged exposure. In addition, in the summer season, the facility house that grows high-income crops is prevalent in molds and pests caused by long-term overheating, and farmers overuse or abuse pesticides.

In addition to spraying the pesticide solution, there are other types of agents that can spray pesticides in the facility, including fumigants, aerosols, and fumigants. Among them, fumigants are not useful because they have very few types. It is also unfavorable in use. On the other hand, smokers are very easy to use, resulting in the least amount of labor and labor time for spraying pesticides.In addition, there is little risk of pesticide poisoning since they can escape from the place of spraying at the same time after the pesticide is installed in the facility. It is the most useful formulation because it has a number of advantages, such as no product value deterioration due to contamination or injury of agricultural products, and no use of water for spraying pesticides, thus eliminating the possibility of causing pests caused by over-humidity. have.

Since these smokes burn themselves at high temperatures, the applicable pesticides must be heat stable and vaporize as active ingredients. The materials used in the smoke-burning smokers are heat generators that generate heat by burning themselves, such as urea acetate-guanidine, nitrocellulose, etc., and chlorinates such as perchlorate and chlorate. Combustion modifiers that can control the combustion temperature include carbon powder, starch, saccharide cellulose and the like. In a general manufacturing method, the active ingredient for agrochemical is mixed with the gunpowder and the auxiliary agent and formed into granules, for example, rod-shaped or disc-shaped.

One example of such a technique is disclosed in Documents 1 to 3 and the like below.

For example, Korean Patent Registration No. 1996-0011194 (published on Aug. 21, 1996), which is Patent Document 1, adds 500 parts of chaff powder to 200 parts of procmidone powder and mixes the mixture with 150 parts of glue powder and sodium perchlorate in another container. 150 parts (or 130 parts of sodium chlorate) are added, and an appropriate amount of distilled water is added to dissolve. Then, the procmidone-rice husk powder mixture is added thereto, followed by kneading. A new plant horticultural pesticide smoker and a method for producing the same are disclosed, which are made into a 4 cm rod shape and dried at 80 ° C. for 3 hours to produce a smoker.

In addition, Patent Document 2, Republic of Korea Patent Publication No. 10-0861704 (registered on September 29, 2008), the fumigation, fumigating agent composition containing the active ingredient of pest control, fumigation, fumigating by an electric heating device and an active ingredient generated during the fumigation, fumigation process By using the control means to spread by natural convection or by the forced blower, the pest control, suppression, and repelling effect can be effectively and conveniently controlled at night even when a person is not resident. Disclosed is a fumigant fumigant composition of agrochemicals in which an active ingredient, an oxidizing agent, a fuming agent, and a combustion rate controlling agent are mixed to form a fumigant adjuvant that is liquefied with general water or distilled water.

In addition, Korean Patent Publication No. 2015-0093311 (published on Aug. 18, 2015), which is Patent Document 3, includes distilled water, an oxidizing agent, a combustion rate regulator, a fuming agent, and chlorine dioxide to prepare a liquid fumigation control agent. , Putting the fumigated smoke control agent prepared in the liquid solution in a heating vessel, gradually heating the heating vessel by using a heat source to gradually evaporate the chlorine dioxide having a low boiling point to fumigation on the crop, the liquid solution of the heating vessel When the water is completely evaporated by heating for a period of time to change the liquid solution to a high viscosity and low thermal conductivity of the mucus, when the temperature of the liquid solution reaches the decomposition temperature of the oxidizing agent by the combustion rate control agent to delay the combustion rate from the mucous Diffusing a large amount of smoke absorbing adhesive and permeable components into the greenhouse space, the greenhouse Disclosed is a control method using a fumigant control agent composition comprising a step of exerting a fume effect on crops by combining smoke diffused into a space and a chlorine dioxide component to produce a fumed particle having adhesion and permeability.

However, in the technique disclosed in Patent Document 1 as described above, the glue powder, sodium perchlorate, distilled water is added and then dissolved, and the procmidone-chaff powder mixture is added thereto, followed by kneading, and the dough is molded by a compression molding machine. There is a problem that the manufacturing time of the product is long because the manufacturing step is complicated, and the drying time is required.

In addition, in the conventional technology as described above, products containing synthetic pesticides, which are effective ingredients used in the prior art, cannot be used as raw materials manufactured through chemical processes as an essential requirement to be equipped with organic agricultural materials at an important point in the environment-friendly enrichment industry. There was also a problem that it could not be organic materials.

That is, in Patent Document 1, a pesticide is used as an active ingredient, an agricultural by-product such as chaff, wood flour or corn cane as an oxidant, an organic or inorganic oxidant as an oxidant, and a water-soluble or oil-soluble adhesive for formulation. Disclosed is a technique that can reduce the problems in the manufacture and use of conventional liquid disinfectant disinfectants or biocides. The technique disclosed in this Patent Document 1 can heat the pesticide as an active ingredient and smoke it together with smoke, so that the active ingredient can be naturally dispersed, but it cannot solve the residual problem of synthetic pesticides. Inorganic oxidizers are simply used for the combustion process to proceed smoothly. Especially, chlorine oxides used as inorganic oxidants such as hypochlorous acid, chloric acid, perchloric acid, etc. are not preferable because they can generate toxic gas chlorine gas during the combustion process. In particular, in the process of preparing a fumigant formulation after kneading by using 150 to 200 parts of adhesive glue and boiling distilled water, a temperature of at least 40 ° C. to 80 ° C. and a drying time of at least 2 hours to a maximum of 12 hours are required. It is undesirable in terms of energy loss and productivity in the production stage, and when the glued dough is formulated with an extruder granulator, the glued and adhered active ingredient has more heat energy during vaporization / sublimation to become gaseous. There was a problem that it was necessary.

An object of the present invention is to solve the problems as described above, low temperature dispersing the environmentally friendly active ingredients for disinfection and salvage without additional energy consumption and disinfection and salvage of agricultural space, such as crop cultivation facility house, etc. It is to provide a smokeless agent using the salt-free smoking process and a method of manufacturing the same.

The above and other objects and novel features of the present invention will become more apparent from the description of the specification and the accompanying drawings.

The term 'smouldering' applied to the present invention is a kind of combustion, low-temperature combustion without flame, and in particular, since the combustion rate is not fast, the evaporation and sublimation rate of the active ingredient proceeds rapidly, thereby reducing the total amount of the active ingredient. It is a method of heating a fumigant that can be dispersed.

The evaporation and sublimation of the active ingredient is applied spontaneously when the temperature rises depending on the type of natural substance in the solid state. When the melting point, which is the physical property of the active ingredient, is reached, it is vaporized into a gas in the molten state. Can be.

The smoke agent using the low-temperature salt-free smoking process according to the present invention includes 60 to 70% by weight of the natural plant powder containing the active ingredient, 20 to 25% by weight of the oxidizing agent and 10 to 15% by weight of the excipient.

The natural plant may be any one or a mixture of Insect flower, Deris, Derris, Quassia, Ryania, Nim, Baekduong.

For these natural plants, any one or a mixture of flowers, leaves, stems, shells, and roots can be used.

Insects are white or red in flower color, and fruit has five veins with achenes, especially in the flower part such as light yellow oil called pyrethrin. This pyrethrin is soluble in organic solvents, highly toxic to insects, paralyzes motor nerves and is used as an insect repellent, and stems and leaves are also used for pest control.

Derris is native to Southeast Asia, the leaves are odd leafy leaves, consisting of 9 to 13 small leaves, and looks like a small egg upside down, a toxic substance called rotenone is used as a pest control agent for aphids.

Ku-Asia is a deciduous tree that grows about 30m and is used as one of the safest materials in home gardening because it controls various pests with little damage to ladybugs and bees. The mixed solution is aphids, mites, insects, moths, fruit flies, It has a contact insecticidal effect on thrips, grasshoppers, moth caterpillars, slugs, ants and mosquitoes.

Liania is a genus of willow and aspens living in tropical jungles in Central and South America. The components of ryanodine have natural insecticidal effects, including deep-rooted moths, larvae, tobacco beetles, assorted worms, cord moths, and king moths. It is effective in lighting insect moth, caterpillar leaf moth, Chinese cabbage butterfly larvae, stink bug tree, cotton gooseot moth, and it is known to have no effect on onion's beetle, soybean aphid, apple mite and tobacco beetle moth.

Nim bark is cold, bitter, astringent, detoxify, clear blood, fruit bitter, used as hemorrhoids, insect repellent. Azadirachtin, the main ingredient, affects the growth and reproduction of insects and is used as a biopesticide.

Baekduong is a pasqueflower, which lives in dry sun and is used as a medicinal herb in oriental medicine, and is used as a natural insecticide for blue beetle, tobacco moth, green chestnut moth, stink bug, whiskers, and the like.

As described above, the natural plant powder is used to finely powder each natural plant, and the size of the fine powder is 80 mesh or more, and the blending amount of the natural plant powder does not exceed the total content of the oxidizing agent and the excipient. The reason for this is the organic manufacturing standard.

The oxidant is used 20 to 25% by weight of ammonium nitrate, when the oxidant exceeds 25% by weight, because the suppression of the fuming process and makes a flame, the high-temperature combustion proceeds to cause thermal decomposition of the active ingredient is disadvantageous, If it is less than 20% by weight, it does not generate a fume process for the role of a smoker for disinfection and relief.

In other words, the present invention includes ammonium nitrate in a 20 to 25% weight ratio to allow the flameless smoking process to proceed at low temperature, and when used to proceed the smoking process using ammonium nitrate (NH ₄ NO ₃ ) Ammonium is primarily decomposed into dinitrogen oxide (N ₂ O) and water (H ₂ O) by pyrolysis reaction (NH ₄ NO ₃ (s) → N ₂ O (g) + 2H ₂ O (g)). Nitrogen is secondaryly decomposed into nitrogen (N ₂ ) and oxygen (O ₂ ) (2N ₂ O → 2N ₂ + O ₂ ). Eventually, ammonium nitrate produces nitrogen, oxygen and water as the final product upon pyrolysis (2NH ₄ NO ₃ (s) → 2N ₂ + O ₂ + 2H ₂ O).

Oxygen generated by pyrolysis helps combustion of flowers, leaves, stems, roots, etc. of natural plants containing active ingredients, and during combustion, active ingredients are vaporized through melting or sublimed in a solid state and dispersed in the air. If only oxygen is supplied as an oxidant, sparks are generated, and if the combustion temperature is increased, active ingredients are destroyed by pyrolysis, and thus, nitrogen generated at the same time acts as a extinguishing agent that suppresses the generation of sparks, thereby allowing the flameless combustion to proceed.

In addition, in the present invention, 10 to 15% by weight of clay mineral is used as an excipient so that the low temperature salt-free smoking process can proceed, and when the excipient exceeds 15% by weight, it hinders the efficacy of the present invention for fumigation disinfection and remedy. If the excipient is less than 10% by weight, the strength of the product during the tablet formation of the smoker is not secured.

Such excipients include bentonite, which is used as an admixture for ceramic raw materials or as an ointment for ointments, pearlite, white pearl-like fine particles, zeolite, an aluminum silicate hydrate, and illite, a mica-based mineral. Any one or a mixture thereof is used.

In the present invention, using the clay mineral as described above, the composition containing the active ingredient at low pressure can be formulated into a tablet, and the contact with oxygen in the air during combustion is minimized compared to the powder state before the formulation of the composition. In the manufacturing and production, it can provide the manufacturer with convenience and efficiency, such as productivity improvement and energy saving. Since the clay mineral powder applied to the present invention has molecular structural properties that can be fine powder or hard strata, the strength of the smoked product must be maintained without disturbing the vaporization and sublimation process of the active ingredient containing the active ingredient even at low pressure. It can be provided, and further formulated by applying a low pressure.

In addition, in the present invention, spontaneous phenomena that can be dispersed in every corner of the space without increasing the humidity by using no water when dispersing the effective ingredients disinfectable and remedy in the space to eliminate the problems as in the prior art Phosphorus diffusion can be applied. Diffusion is a natural phenomena in which a substance moves due to a difference in concentration of a substance, which is the best way to disperse it in a wide space naturally.This is necessary to make the active substance gaseous by vaporization or sublimation to allow the diffusion of space, thereby heating the active ingredient. By overcoming intermolecular forces and increasing the distance between molecules, the diffusion of gasified active ingredients can be expected. In particular, in order to prevent the thermal decomposition of the components when the active ingredient is heated to provide a composition capable of low-temperature combustion and non-flammable combustion, composition and structural that can be effectively blocked with oxygen in the air in the course of combustion Form can be provided.

That is, in the present invention, in consideration of low-temperature combustion and flameless combustion, a smoke agent having the composition as described above was prepared.
