Description

[Detailed description of the invention] [l#, field of application of business owner] The present invention provides organic phosphorus compounds, carbamate compounds,
The present invention relates to a soil treatment agent for termite prevention, which contains a termite prevention agent selected from pyrethroid compounds and triazine compounds as an antitermite component.

[Prior Art] Chlordane, an organic chlorine compound, has been commonly used as a termiticide to exterminate termites. Chlordane has long been used because it has a residual effect, is difficult to decompose, and maintains its anti-termite effect for a long time. However, this property of being difficult to decompose has become a pollution problem, and the use of chlordane has come to be regulated.

Therefore, organic compounds, carbamate compounds, pyrethroid compounds, and triazine compounds are attracting attention as termiticides that can replace chlordane. Although these termiticides have a strong insecticidal effect, they are degradable in the soil and have no residual properties, so their use is approved because the risk of environmental pollution is low.

These termiticides are generally used in the form of a latex, and this latex is sprayed on the soil under the floors of houses to treat the soil against termites.

[Problems to be Solved by the Invention] However, many of the organophosphorus compounds and carbamate compounds used as termiticides have strong acute toxicity, and pyrethroid compounds and triazine compounds can also be harmful if exposed to large amounts. There is a risk that the safety of workers cannot be ensured if the emulsions of these termiticides are scattered during spraying, as they may have an adverse effect on the body. In addition, this emulsion is easily washed away by water after spraying, and there is a risk that the anti-termite effect will be significantly reduced, and in some cases, there is a risk that it may enter wells, sewage, rivers, lakes, oceans, etc. and pollute the environment. Furthermore, this emulsion is easily diffused and diluted in the soil, and in order to ensure the anti-termiticide effect, the amount of the active ingredient for the termiticide is approximately 50 to 100 g/ls2 for organic phosphorus compounds and carbamate compounds, and approximately 50 to 100 g/ls2 for pyrethroid compounds. There is also the problem that it is necessary to spray a large amount of about 10 to 150 g/lI2, and about 200 to 300 g/m'' for triazine compounds, and these termiticides are easily decomposed by alkalis with a pH of about 11 or higher. Particularly in soil, there is a problem that the termiticide effect is reduced due to rapid decomposition, and the effective period is very short.Furthermore, some of these termiticides are easily volatilized and transpired, and are susceptible to damage caused by microorganisms in the soil. Some substances are easily susceptible to decomposition, and all of them cause shortening of the effective period.

The present invention has been made in view of this point, and is
+7-based compounds, carbamate-based compounds, pyrethroid-based compounds, and triazine-based compounds can be used as termiticides to ensure safe construction, prevent them from being washed away by water, and prevent them from penetrating and diffusing into the soil. It is an object of the present invention to provide a soil treatment agent for termite prevention that can prevent the termite-preventing effect from being degraded by alkali and soil.

[Means for Solving the Problems 1] The soil treatment agent for termites according to the present invention comprises a termiticide selected from organophosphorus compounds, carbamate compounds, pyrethroid compounds, and triazine compounds, and a synthetic resin emulsion. It is characterized in that it is made by dispersing and blending water and inorganic powder.

In addition, in the present invention, 5! ! The organic powder has a pH of 10°5

Furthermore, the blending amount of each component is 0.1 to 5.0% by weight when using an organic phosphorus compound as a termiticide, and 0.1 to 5.0% by weight when using a carbamate compound. % by weight, 0.01 to 5 when using a pyrethroid compound

It is desirable that the amount of water be 5 to 30% by weight.

The present invention will be explained in detail below.

In the present invention, the termiticide selected from the group consisting of fi+7-based compounds, carbamate-based compounds, pyrethroid-based compounds, and tri-7-non-based compounds is used singly or in combination.

．． 1 to 5.0% by weight, 0.1 to 5.0% by weight when using a carbamate compound, 0.01 to 5% by weight when using a pyrethroid compound, and 1% by weight when using a triazine compound. It is preferable to set it in the range of 1°0 to 10.0% by weight.

If the upper limit of these ranges is exceeded, toxicity problems may occur, and if the amount is less than the lower limit, sufficient anti-termite effect cannot be obtained.

In addition, each of the termiticides mentioned above is generally a poorly water-soluble oil-soluble substance, and is prepared in advance into a form suitable for formulation as an anti-termite soil treatment agent, such as an emulsion, a powder, a wettable powder, a 707 pull agent, or a water solvent. It is preferable to prepare an emulsion by dissolving a termiticide that is poorly soluble in water in a relatively small amount of an organic solvent, and then adding an emulsifier to improve dispersion and stabilize the emulsion. Powders are prepared by mixing a termiticide that is poorly soluble in water with a relatively small amount of fine mineral powder.Water powders are prepared by mixing a termiticide that is sparingly soluble in water in a relatively small amount. It is prepared as a powder mixed with a small amount of fine mineral powder, and by adding a small amount of surfactant, when diluted with a large amount of water, the termiticide is dispersed in water to form a stable suspension. 707 pull agent is a solution of a termiticide that is poorly soluble in a solvent, and can be prepared by pulverizing the termiticide into a fine powder and dispersing it in water. Aqueous solvents are prepared as a powder by mixing a water-soluble termiticide with a water-soluble filler or auxiliary agent.Among the above, hydrocarbon-based solvents are most suitable for use in emulsions. However, toluene, xylene, ethylbenzene, cumene, turpentine, mineral split, kerosene, No. 3 solvent, No. 4 solvent, etc. can be used.

As the synthetic resin emulsion, it is better to use one obtained by preparing a synthetic resin by emulsion polymerization rather than one obtained by emulsifying a synthetic resin with an emulsifier. In the case of Dimalgin, which is a synthetic resin emulsified with an emulsifier, there may be restrictions on the types of resins and emulsifiers that can be used, but the synthetic resin obtained by emulsion polymerization is essentially water-insoluble and dispersible. They have the aptitude of being good at nature.

In this synthesis, resin emulsions include acrylic ester, methacrylic ester, vinyl acetate, vinyl propionate, vinyl versatate, ethylene, styrene,
It is possible to use those prepared by emulsion polymerization of 7-crylonitrile alone or in a copolymerization system of two or more types.

Among these, an acrylic resin emulsion containing acrylic ester as a main component is most suitable. This acrylic resin-based emulsilane contains acrylic acid Nistermo 7mer or other monomers copolymerizable with it, anionic surfactant or emulsifier such as/ionic surfactant, and persulfate or hydrogen peroxide. It is obtained by emulsion dispersion in water in the presence of a water-soluble polymerization initiator and emulsion polymerization. Examples of anionic surfactants include Sorg dodecylbenzenesulfonic acid, Sorg lauryl sulfate, and sodium dioctyl sulfosuccinate. As the /ionic surfactant, polyoxyethylene/nyl 7enyl ether, polyoxyethylene stearate, polyoxyethylene sorbicun monolacrylate, polyoxyethylene polyoxypropylene block copolymer, etc. may be used. Can be done. Acrylic esters suitable for use include methyl acrylate,
Examples include ethyl acrylate, propyl acrylate, butyl acrylate, or 2-ethylhexyl acrylate, but it is preferable to copolymerize 20% by weight or more of butyl acrylate or 2-ethylhexyl acrylate. desirable. Furthermore, other monomers that can be copolymerized with these acrylic esters, such as methacrylic esters such as methyl methacrylate, acrylonitrile, vinyl acetate, styrene, etc., can also be partially copolymerized. It is preferable to prepare the synthetic resin emulsion thus obtained so that the minimum film forming temperature is 10°C or less. If the minimum film forming temperature is higher than 10°C, film forming defects may occur and a large number of cracks are likely to occur (this tendency becomes more obvious as the temperature during treatment becomes lower, and the termite prevention effect becomes incomplete).Also, the resin component concentration of the synthetic resin emulsion is 40 to 60% by weight.
It is preferable to set it within a range of %. The appropriate amount of the synthetic resin emulsion to be blended is 10 to 30% by weight in terms of resin solid content based on the total amount of the anti-termite soil treatment agent. If it is less than 10% by weight, the formation of a continuous phase (matrix) of the resin in the formulation or after application will be incomplete, and there is a risk that large cracks will occur in the formed film after application, allowing termites to pass through these cracks. In addition, there is a risk that the dispersibility of the inorganic powder in the soil treatment agent for termite prevention may decrease, causing the mineral powder to settle. Failure may occur. If the amount exceeds 30% by weight, the amount of resin relative to the termiticide becomes too large, and the concentration of the termiticide becomes too low, which may weaken the termiticide effect.

It is also desirable to include an emulsifier in order to diffuse the termiticide into the soil treatment agent and bring it into contact with the synthetic resin of the emulsion. As the emulsifier, for example, alkylbenzene sulfone polyoxyethylene alkyl phenol ether, polyoxyethylene moa alkyl ether, etc. can be used, but if a suitable emulsifier is already included in the synthetic resin emulsion, there is no need to add a separate emulsifier. do not have. If the emulsifier is used in a larger amount than the termiticide, the soil treatment agent for termite prevention tends to foam, so the amount of emulsifier added is 1 part by 1 part per total amount of the soil treatment agent for termite prevention.
It is preferable to set it to % or less.

Inorganic powder is formulated to prevent termite-control soil treatment agents from permeating into the treated soil and to maintain the concentration of termiticide in the formulation. It is suitable for use as a soil treatment agent for termites. Due to the influence of H, inorganic powders tend to be limited in the range of p) (i.e., if the pH of Bortland cement is greater than 10.5, the termiticide decomposes due to the influence of alkali). Therefore, it is preferable to use an inorganic powder with a pH of 10.5 or less, such as quartz powder, silica powder, silica sand, alumina, kaolin, clay, talc, calcium carbonate,
Perlite, vermiculite, shirasu balloon, etc. can be used. The blending amount is 4 for the total amount of anti-termite soil treatment agent.
0 to 85% by weight is good. If the blending amount is less than 40% by weight, the amount is insufficient to keep the matrix consisting of the termiticide and synthetic resin adsorbed on the surface of the inorganic powder, and the excess matrix that is not adsorbed to the inorganic powder will be absorbed into the soil. There is a risk that it will dissipate. On the other hand, if the blending amount exceeds 85% by weight, the surface of the inorganic powder will not be covered with the matrix, which will not only deteriorate the fluidity and storage stability of the anti-termite soil treatment agent, but also cause the film to form after application. This can cause cracks to form, allowing termites to enter. The optimal value of the blending amount is s
Although it varies greatly depending on the particle size and specific gravity of the skeletal powder, and the properties of the interface, for example, silica sand and calcium carbonate have a
It is about 0 to 65% by weight.

In order to maintain the fluidity suitable for the spray method in the soil treatment agent for termites, it is necessary to contain 5 to 30% water by weight (the lower limit is precisely the organic phosphorus-based 4. When using compounds or carbamate compounds.
9% by weight, 4.9 when using a pyrethroid compound
If the moisture content is less than 5% by weight, the fluidity of the anti-termite soil treatment agent will be insufficient, making it difficult to spread it, making it difficult to apply. may become difficult. Furthermore, if the water content exceeds 30% by weight, there is a risk that the synthetic resin emulsion will float on the surface of the anti-termite soil treatment agent, or that the anti-termite soil treatment agent will seep into the soil during construction and the termiticide will be lost. Also, it takes a long time to dry during construction. The amount of water added is determined by adding up the amount of water contained in the synthetic resin emulsion. Water is evaporated when an anti-termite soil treatment agent is sprayed on the soil to form a film that covers the surface of the soil.

To formulate a soil treatment agent for termites, collect the above ingredients, mix them, and mix them with a stirrer (this can be done by dispersing them into a suspension. First, a termite-proofing agent and an emulsifier are mixed to make a solution of the termite-proofing agent, and the synthetic resin emulsion, inorganic powder, and water are dispersed and mixed using a high-speed stirrer, and the two are mixed together. When dispersing and mixing the synthetic resin emulsion, inorganic powder, and water, a general-purpose dispersant or antifoaming agent may be added to assist the dispersion. In order to ensure the storage stability of the soil treatment agent for ants, a preservative is added, and short fibers are added to prevent the membrane from tearing after construction. The termiticide is used by spraying it on the soil surface under the floor to form a film, and the termiticide is dissolved in the water-insoluble synthetic resin of the synthetic resin emulsion and protected by the synthetic resin matrix. This prevents the termiticide from being washed away by water after construction, and also prevents alkali and soil from acting on the termiticide and causing it to decompose. The effectiveness of the termiticide is surprisingly long-lasting, far exceeding expectations, and can be effective for a long period of time.Also, the termiticide is adsorbed and retained on the surface of the inorganic powder, and the termiticide is absorbed into the soil. This prevents the termiticide from penetrating, diffusing, and diluting, and eliminating the need for large amounts of spraying.Also, the termiticide is absorbed into the film without being washed away by water or permeating into the soil. Because of this, the strong anticide effect can be sustained even when diluted to 1% by weight or less. In addition to ensuring the safety of workers during construction, the viscosity of the anti-termite soil treatment agent is increased by adding synthetic resin emulsion and inorganic powder to prevent scattering during spraying. It is possible to prevent this from occurring, and in this respect as well, the safety of the construction worker can be ensured.

The film formed on the soil in this way can also be expected to have a moisture-proofing effect under the floor.

"Fluidity" After adjusting the temperature of the sample to 20℃ using a constant temperature water bath,
The viscosity was measured using a type viscometer at 12 rpm to evaluate the fluidity.

"Storage Stability" The sample was placed in a 142-glass container and sealed, and stored for 61 hours at room temperature.
After being left for one month, the package was opened and the contents were stirred to check for uniformity, including the presence or absence of coarse particles.

In addition, after the sample was heated to 20° C. gq, the viscosity was measured using a B-type viscometer at 12 rpm to examine changes in viscosity.

"Sprayability" A sample was sprayed with a mortar gun having a diameter of 6 mm, and the difficulty of the spraying operation and the dispersion of the spray mist to the surrounding area were observed.

``Water leaching 1'' A sample of 2.0 kg/l was applied to the soil surface using a mortar.
Spray at a spray rate of 112, dry thoroughly to form a film, peel off the film, immerse it in a plus container filled with water and leave it at 40°C for 7 days, then remove the water. The amount of termiticide eluted into the water was analyzed by chromatography.

[Anti-termite efficacy J] Spread quartz sand in a 9 cm diameter petri dish, adjust the moisture content to 5%, then spray the sample at a spray rate of 2.0 kg/w2, dry thoroughly indoors, and place in this petri dish. 20 termites were introduced into the tank, and the response rate and mortality rate were observed. Here, the reaction rate is calculated using the following formula.

Next, the exposed soil surface was treated with the sample at a rate of 2.0 kg/m2, and then 5X5X20cm was spread on the bricks.
7 pieces of dried Japanese larch wood was placed and a lid was placed on top. After 2 years, the anti-termite performance and the performance of the sample membrane were observed.

Termite-proof performance is determined by whether or not termites are acting on red pine wood! The membrane performance was evaluated by observing whether or not cracks were generated in the membrane. A case where termites were not acting on the red pine wood and no cracks or the like were generated in the film was judged as good.

Table 1 (parts by weight) Table 2 The results shown in Table 2 show that in Comparative Example 1, which did not contain a synthetic resin emulsion, the inorganic powder settled, resulting in poor storage stability (and poor dispersibility). In addition, it was confirmed that because a film was not formed, chlorpyrifos tended to be leached and the termite prevention effect decreased, and in Comparative Example 2, which did not contain inorganic powder, the viscosity was low (so when spraying, it was difficult to mist it). It was confirmed that a large amount of particles were scattered, which is not desirable from the viewpoint of construction hygiene.On the other hand, the products of each example containing synthetic resin emulsion or inorganic powder along with chlorpyrifos showed poor storage stability, dispersibility, Good results were obtained in terms of water leaching resistance, anti-termite efficacy, aging condition of the membrane, and long-term outdoor performance.

[Effect of the invention 1 As described above, the soil treatment agent for termite prevention according to the present invention comprises a termite prevention agent selected from an organic phosphorus compound, a carbamate compound, a bilestoid compound, and a triazine compound, a synthetic resin emulsion, and an inorganic powder. Since the termiticide is prepared by dispersing and blending the termiticide in water, it is protected by the synthetic resin of the synthetic resin emulsion and is not washed away by water or decomposed by the action of alkali or soil. In addition, the termiticide is adsorbed and retained on the surface of the inorganic powder, and can prevent the termiticide from penetrating into the soil and being diluted by diffusion. It is. Moreover, because the termiticide is retained in the film without being washed away by water or permeated into the soil, it maintains its strong termiticide effect even when used diluted. This makes it possible to lower the concentration of the anti-termite soil treatment agent and use it in a less toxic state to ensure the safety of workers during construction. By incorporating inorganic powder, the viscosity of the anti-termite soil treatment agent can be increased to prevent scattering during spraying, thereby ensuring safety for construction workers.
