Abstract

PURPOSE:An expellent for insect pests such as acarid, termite, etc., in the interior of a house, obtain by diluting an agent having acarid controlling and exterminating power with an alcohol and water to give a stock solution and blending the stock solution with a cationic acrylic resin as an effective very small amount component so that effect of the agent component is continued for a long period. CONSTITUTION:An agent having acarid controlling and exterminating powder, preferably insecticide for insect pests such as acarid, termite, etc., in the interior of house, antiseptic or mildew-proofing agent is diluted with an alcohol and water to give a stock solution, which is blended with a cationic acrylic resin, preferably acrylstyrene as an effective very small amount component so that the resin is reacted with an alkali component of a material such as TATAMI (straw matting), concrete, wood, etc., and cured to leave the agent attached to fine parts of the material, to prevent decomposition caused by oxidation and ultraviolet rays and to continue the effects of the agent for a long period. Since the amount of the resin blended is a very small amount, the resin neither closes venting hole nor damages air permeability.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention is useful for controlling mites such as mites such as mites and mites that occur on tatami mats and carpets, as well as indoor pests such as termites, black ants, and cockroaches. Concerning pesticides that are effective for long periods of time in pest control and extermination.

(Prior art) Conventional medicines for exterminating household dust mites, etc. are solutions in which a mite exterminating ingredient such as organic phosphoric acid-based Sumithion oil is added and dissolved in a solvent. At the time, they were spraying or coating tatami mats, carpets, and floors under tatami mats. Also, particularly recently, aerosols have been used that inject drugs by piercing the tatami with a needle attached to the IAn.

Note that extermination of mites includes killing mites as insects.

(Problems to be Solved by the Invention) However, with this conventional chemical, although it is injected into the inside of the tatami mat or sprayed on the back side of the tatami mat, it is difficult to use the chemical because of the volatility of solvents, oxidation, and decomposition due to ultraviolet rays. The problem is that the residual period of the drug is short, and it evaporates before it penetrates deep into the strongly compressed tatami mats, causing its medicinal efficacy to disappear in a short period of time, making it impossible to effectively control and exterminate indoor pests such as mites. Ta.

(Means for Solving the Problems) Is the present invention intended to solve these conventional problems? The purpose of this method is to thoroughly remove mites deep into tatami mats, concrete, wood, etc. by spraying or delaying the volatilization of solvents after application to control and exterminate indoor pests such as mites and termites.・Infiltrate the product with an agent to control and exterminate indoor pests such as termites, and then incorporate the agent into a thin film and attach it to the details of materials such as tatami mats, concrete, and wood. The purpose of the present invention is to provide a control agent for indoor pests such as mites and termites that can be left for a long period of time to maintain its exterminating power against mites for a long period of time. A cationic acrylic resin was mixed as an effective trace ingredient into a drug substance with exterminating power diluted with alcohol and water.

(Function) Therefore, in the present invention, a cationic acrylic resin is mixed as an effective trace ingredient into the active substance that has the ability to control and exterminate indoor pests such as mites and termites. When sprayed on the surface of flooring materials such as dust mites, termites, etc., the agent to control and exterminate indoor pests such as mites and termites penetrates into the interior of tatami, concrete, and wood, and after adhering to the details of the materials, the cation/type acrylic resin It reacts with the alkaline component in the material to contain and harden the agent for controlling indoor pests such as mites and termites, so this agent for controlling indoor pests such as mites and termites can be used on tatami, concrete, wood, Dust mites remain inside.
This cationic acrylic resin cures to cover the base material for a long period of time, and this resin film blocks ultraviolet rays and air, preventing decomposition and oxidation of the base material. do. This allows the efficacy of the medicinal ingredient of the active ingredient to be sustained over a long period of time. Also, since the amount of resin mixed in is @ amount, this is the amount of resin mixed in with tatami mats, concrete, etc.
It does not harden by covering the spaces or minute ventilation holes in the wood and does not impair the breathability of the material.

(Example) The present invention will be explained in detail below.

Table A shows the composition of the acaricide of the first example, and in the table, inpropyl alcohol is a solvent and has the ability to penetrate into the tatami material. Furthermore, since butyl cellosolve has low volatility, it controls the volatilization of the drug.

Also, acrylic styrene in the table is a cationic acrylic resin, and its main principle is that it adheres to minute parts of the tatami material together with other base materials, and reacts with the alkaline components of the tatami material to harden.

In addition, the insecticides, preservatives, and fungicides listed in the table diluted with alcohol and water are the active ingredients for controlling and exterminating mites, and among these, the preservatives and fungicides remove the food necessary for mite reproduction. It is effective for controlling and exterminating mites even when used alone. Therefore, in addition to the above-mentioned active ingredients for controlling and exterminating mites, it is also possible to use only insecticides, only preservatives, only fungicides, or a combination of two of these agents.

The results of the mite control and extermination test according to this example are as follows.

(1) Change in the number of live mites During the test period, live mites such as Aceridae and Dermatophagoides were detected, and the average number before the test was 4.5 individuals, but after the test, the number increased to 8 individuals per day. After 1 week, the number of puss decreased by 2, and after 1 month, the number of puss decreased by 2.

(2) Changes in the number of dead mites Before the test, 4,824 dead mites of the Physiophyllinidae family, Isa saladani, Deterinary mites, and other dead mites were detected, and after the test, the average was 98 mites per white, 82 per week, and 1 month. This resulted in 23 individuals.

The following can be confirmed from the above.

(b) Live mites were 44.4% of the level before treatment one week after chemical treatment.
The number decreased to 0 in one month, indicating that water chemical treatment was effective.

(b) The increase in live mites one day after chemical treatment is due to
l! It is thought that it may be something similar, or it may be due to daily fluctuations.

(c) The number of dead mites was 6.8% of the pre-treatment level one week after treatment.
In one month, it decreased to 2%.

According to the results of this investigation, it was confirmed that the active substance according to the example remained for a long period of time and was effective in controlling and exterminating the number of mites.

Table Bii shows the composition of the acaricide of Example 2.

This example is characterized in that the quantitative proportion of isopropyl alcohol is increased to strengthen the penetrating power.

Table B and Table C show the composition of the acaricide of Example 3, and in this Example, the quantitative proportion of isopropyl alcohol was further increased by 1, and butylceronlube was removed. There are characteristics.

This example is an example in which the drying of tatami mats is speeded up by making the volatility extremely strong, thereby reducing moisture, which is the breeding condition for mites, and allowing them to pass through, thereby increasing the pest control effect.

This is mainly used for jutano and sofa.

Table C: How to use each of the examples above is to apply the undiluted solution to the back, sides, floor surface under tatami mats, etc., at a rate of 60 cc to 90 cc per square meter.
It is sufficient to spray c.

(Effects of the Invention) According to the present invention, a cationic acrylic resin is mixed as an effective trace ingredient in a car body cleaner that has the ability to control and exterminate 1 and 14 indoor pests such as ticks and white fleas. ,
Concrete, wood, etc. reacts with Alka J5i and becomes feces, leaving a residue for the control of insects inside the house, such as mites and termites that are found in the minute parts of tatami mats, concrete, and wood. Long-term: Mites can be exterminated for a long period of time. In addition, the air permeability of tatami, concrete, and wood can be maintained without closing the spaces and minute ventilation holes in tatami, concrete, and wood.

Moreover, it can be manufactured on a cheap F111i, and even if it is manufactured by a single manufacturer, special techniques and tools are required, so it has the advantage that anyone can easily use it.
