Abstract

The present invention relates to a method of preparing a mosquito repellent composition which is conceptually different from insecticides in that the mosquito repellent composition repels, rather than exterminates, mosquitoes. The composition prevents mosquitoes from approaching and entering by desensitizing their navigational instinct to gather near human habitations to consume blood, and since the repellent effect lasts for long periods of time, pleasant environments free of mosquitoes can be maintained for long periods of time. The method comprises the steps of: (a) preparing and naturally drying 45-55% of Zanthoxylum piperitum barks and 45-55% of Zanthoxylum piperitum leaves; (b) adding sulfur powder to water and heating to about 40-50C to prepare a sulfur water, and while maintaining the sulfur water at about 20-30C, immersing the Zanthoxylum piperitum barks and leaves therein and aging for 2-7 days; (c) preparing, mixing, and naturally drying 20% of each of Pelargonium citrosum vanleenii, Chrysanthemum cinerariaefolium, Eucalyptus globulus, Cinnamomum cassia, and Ocimum basilicum; (d) placing the Pelargonium citrosum vanleenii, Chrysanthemum cinerariaefolium, Eucalyptus globulus, Cinnamomum cassia, Ocimum basilicum into water mixed with butylene glycol and heating for 10-30 minutes for a first time and cooling, and then heating again in a water bath at 75-80C for 4-6 hours for a second time and cooling to produce an extract mixture water; and (e) mixing the aged sulfur water with the extract mixture water in the ratio 6 : 4 to produce a complex extract water.

TECHNICAL FIELD SAID COMPOSITION AND WATER PAINT PRODUCED BY THEREOF METHOD}

The present invention relates to a method for producing a composition having a mosquito repellent effect, a composition prepared thereby, a method for producing a water-based paint using the same, and a water-based paint prepared by the method, and more particularly, It is intended for the avoidance effect, not the insecticide concept. The mosquito is paralyzed (slowed down) to instinctively approach the place where people stay for blood vomiting, thereby blocking the entry and access of the mosquito, The present invention relates to a method for producing a composition having a mosquito repellent effect, which is capable of maintaining a pleasant environment blocked from a mosquito for a long period of time, a composition prepared thereby, a method for producing a water-based paint using the same, and a water-

Mosquito is a pest that mediates various diseases such as malaria, encephalitis, yellow fever and dengue fever, as well as directly or indirectly damaging the people by interrupting sleeping and restricting outdoor activities.

Various solutions have been studied to protect the human body from the attack of these mosquitoes. Among them, there is no effect of killing the mosquitoes in the representative method. However, the mosquito contains a substance that the mosquitoes dislike, .

However, since the repellent is a human body to be directly used, it must contain a control function capable of stimulating the senses of the mosquito, so the requirements of the chemical components such as the effects on the human and the ecosystem or the side effects are very difficult.

DEET (N, N-diethyl-m-toluamide or N, N-diethyl-3-methylbenzamide) is the most widely used synthetic herbicide, Although it has an avoidance effect, it has an unpleasant and irritating odor. Due to the high penetration of skin, pregnant women, children, hypotensive patients and sensitive skin patients are limited in their use. Even in healthy adults, And it has a problem that it reacts with some plastics or synthetic rubber to cause discoloration or the like.

Accordingly, studies on repellents capable of replacing DEET have been actively carried out. Recently, there have been a lot of researches on repellents that can replace DEET. In recent years, research has been conducted on natural products such as Thymus quinquecostatus, Carvacrol, Thymol, Although a repellent agent containing a substance has been proposed, the effectiveness of the mosquito repellent agent has been greatly reduced compared to DEET, and the practicality has been questioned. Also, since the duration of the repellent effect after spraying and application is short, it has been troublesome to treat it several times.

In addition, in case of spraying on clothing, it has a temporary effect, but due to its high volatility characteristic, its efficacy disappears after a certain period of time, and therefore, it requires economical and time-consuming periodical spraying for continuous defense.

Especially, it has been experimented to include existing mosquito repellent in long-term use of interior and exterior coatings. However, in this case, the mosquito repellent effect is maintained only for a short period of time, Development of mosquito repellent agent is required in the paint industry.

The object of the present invention is to solve the above-mentioned problems, and it is an object of the present invention to provide a mosquito- The present invention relates to a method for producing a composition having a mosquito repellent effect that is capable of maintaining a pleasant environment blocked from a mosquito for a long period of time by blocking parasitic infestation, A composition, a method for producing a water-based paint using the same, and a water-based paint prepared by the method.

Hereinafter, the present invention will be described in more detail.

The present invention relates to a method for producing a composition having a mosquito repellent effect, which comprises a step of stimulating the olfactory and motor nerves of a mosquito to slow the instinctive motor nerves of the mosquito (Artichoke) and a liquid extract material obtained by treating leaves, leaves, fruits and the like of natural plants are mixed to obtain a composition having a mosquito repellent effect.

The composition according to an embodiment of the present invention can be applied to a variety of plants such as natural materials such as Zanthoxylum piperitum, Pelargonium citrosum vanleenii, Chrysanthemum cinerariaefolium, Eucalyptus globulus, Cinnamomum cassia, Ocimum basilicum ), And the like.

The above-mentioned superfine tree has a somewhat different name depending on the region. It is variously called "Joe-bok-yi" (north), "jinhyeong" (gyeongsang), jinpyeol It is not used to weave oil, but it is used as a spice, food additive, and seasoning because of its unique flavor and poisonous taste. The spicy components and fragrance of the primrose trees are almost non-toxic to humans, but they are very toxic to insects such as mosquitoes and flies and to animals such as fish, pigs and ducks. It has a powerful antimicrobial effect on the trees, which is highly effective in eradicating small insects and larvae. In other words, it has a considerable effect on harmful bacteria and microbacterial disinfection. This primrose contains citronella components that have a mosquito repellent effect.

The paprika is able to collect citronella natural fragrance from the leaves. By adding and mixing it, Insect Repellent Perfume, which is possessed by this steering, effectively blocks insects such as mosquitoes from approaching the human body And can be eliminated.

The bug bug station has a substance such as a pale yellow-yellow oil called pyretrin in the plant, especially in the flower part. Pyretrin is dissolved in organic solvents. It is characterized by strong toxicity to cold blooded animals, especially insects, which paralyze motor nerves, but are not toxic to warm-blooded animals.

The eucalyptus is an evergreen tree or a shrub belonging to the plating thick-sheath plating and emits fragrant fragrance, but it is suitable for mosquito eradication because it has an incense which pests do not like. Eucalyptus has no toxicity to humans, and it exerts particularly good avoidance effects against mosquitoes, ticks, fleas and the like. Such eucalyptus can be used together with citronella and the like to exert a repelling effect on a very wide variety of insects.

The cinnamon tree is a natural medicinal plant belonging to the genus Cambicaceae. It is mainly used in southern China and Vietnam, and is widely used in Chinese medicine and fertilizer in Korea. It is used as a therapeutic agent for circulatory system of blood vessels and blood, and is used as a cold treatment agent and analgesic agent due to sweating, antipyretic, and dust effect. It is also known to have a very good effect as an antimicrobial and anti-mite effect and a pest control agent. Especially, the fragrance of cinnamon aroma is recognized as a good smell by humans, while it is very toxic to mosquitoes, so it can be used effectively as a mosquito repellent when this aroma is diffused.

The plant extracts of methanol, petroleum ether and carbon tetrachloride of leaves have a mosquito repellent effect and a mosquito larva insecticidal effect.

Now, a preferred embodiment of a method for producing a composition having a mosquito-repelling effect according to the present invention will be described in detail with reference to Fig.

1 is a flow chart for explaining a method for producing a composition having a mosquito repellent effect according to the present invention.

First, as step S10, a sulfur-fermented fermented water of a primavera is prepared.

More specifically, a superfine wood material having a total weight of 30 kg consisting of 40 to 60% of the shell of the superfine tree and 40 to 60% of the flyfat is prepared. Here, the material is crushed to a size of about 1 cm, and after the crushing, the material is naturally dried for about 100 to 150 hours in a shady place at room temperature.

Then, 20 to 30 kg of sulfur powder is added to 100 liters of water, and the mixture is heated to about 40 to 50 DEG C to obtain sulfur water by dissolving the sulfur powder in water. The temperature of the obtained sulfur water is maintained at about 20 to 30 DEG C 30 kg of the prepared early-ripened bark and persimmon leaves are immersed in the sulfuric water and naturally fermented for 2 to 7 days to be aged to produce 60 L of fermented sulfur-fermented water.

The reason why sulfur is used is that the amino acid cysteine, which is the main component of sulfur, detoxifies the human body, but even if exposed to a very small amount of sulfur dioxide (SO ₂ ), the olfactory nerves and motor nerves are slowed, . Especially when the naturally fermented product is immersed in the sulfur water for 2 to 7 days by immersing it in the sulfuric water, the components (tannin, hyperperin, xanthoxylin, etc.) The duration of the sulfur component is doubled, so that the mosquito repellent effect can be maintained for a long period of time.

Next, in step S20, a mixed extract of paprika, a bug bug, an eucalyptus, a cinnamon tree, and a spatula grass is produced.

Prepare a mixed material with a total weight of 30 kg consisting of 20% of each of paprika, pest control, eucalyptus, cinnamon, and spatula. Here, the material is crushed to a size of about 1 cm, and after the crushing, the material is naturally dried for about 50 to 90 hours in a shaded area at room temperature.

Separately, a mixed solution is prepared by mixing 8 to 12 L of Butylene Glycol in 100 L of water.

The mixture is heated for 10 to 30 minutes at a temperature of 100 ° C. for about 10 to 30 minutes. The temperature of the mixture is gradually lowered to about 75 to 90 ° C., After heating at 80 ° C for about 4 to 6 hours, heating is stopped and the mixture is cooled at room temperature to produce 40 liters of mixed extract.

Here, when the mixed solution containing pycnopenia, insecticide, eucalyptus, cinnamon, and rice flour is first boiled at 100 ° C, the tissue bond of the solid such as dried peel or persimmon can be rapidly relaxed and softened, Extraction is facilitated.

In addition, if it is added to the bath again for about 4 to 6 hours, the maximum value of the adduct component extract can be obtained. Of course, it is possible to proceed for 6 hours or more, but as a result of the experiment, the extraction rate of the adduct component no longer increased even if it was heated for 6 hours or more.

As a result, it was confirmed that butylene glycol used as the solvent enhances the adduct extraction rate as compared with other solvents.

Next, in step S30, the sulfur-fermented fermented water of step S10 and the mixed extracted water of step S20 are mixed at a ratio of 5: 5 to 7: 3, preferably 6: 4, .

For example, 60 liters of fermented sulfur fermented with supercritical fluids and 40 liters of mixed extracts using fescue, insecticide, eucalyptus, cinnamon, and barley grass are mixed to produce 100 L of a combined extracting liquid having a mosquito repellent effect.

Here, optionally, the Citronella essential oil mixing process of step S40 can be further roughened.

That is, 0.5 to 0.9 L of citronella essential oil can be mixed with 100 L of the combined extracting water having the mosquito-repelling effect as described above. This can enhance the directionality of the combined extract water and increase the blocking rate of various insect pests including mosquitoes.

Meanwhile, by applying the composition having the mosquito-repelling effect thus prepared to water-based paints, it can be used as interior and exterior paints for general households and offices, so that a comfortable environment in which the space is blocked from mosquitoes can be maintained for a long time.

Here, a water-based paint using glue and casein as a vehicle is used for a long time. It is economical using water instead of an organic solvent and is low in ignitability, so that it is safe and easy to handle. Examples of water-based paints include emulsion paints and water-soluble baking resin paints. The emulsion paints are vinyl-acrylic-styrene-butadiene-based emulsion polymerization (emulsion polymerization) As a vehicle. The water-soluble baking resin coating material is a paint using a water-soluble resin such as a modified alkyd resin, a phenol resin, a melamine-modified acrylic resin and an amino resin as raw materials and using water as a solvent.

In the present invention, the amount of 60% of the total amount of water used in the production of water-based paints is reduced to 15%, and the amount of water of 45% is replaced by a composite extracting water, which is a composition having a mosquito repellent effect.

That is, by replacing 50% or more of the total amount of water used in the water-based paint with the above-mentioned composite water, it is possible to produce a water-based paint having a mosquito repellent effect. Preferably, the water used for the water- 3. ≪ / RTI >

<Experimental Example>

The purpose of the experiment was to measure the mosquito repellent effect of the combined extract water according to Examples 1 to 4.

For this purpose, mosquito repellent effect was arithmetically measured by mixing mulberry extracts mixed with water - based paint, inserting a number of mosquitoes into experimental hardboards coated with water - based paints, and checking the number of mosquitoes sitting on the hardboards.

In the experiment, a water-based paint was prepared by reducing the amount of 60% of the total amount of water used in the manufacture of water-based paints to 15% and replacing the amount of 45% of water with the composite water according to Examples 1 to 4.

The experiment was carried out from October 1, 2015 to December 31, 2015 at the Institute's Research Institute (SHK R & D Research Institute) of Paperless Wallpaper Co., Ltd. of the applicant's laboratory.

The mosquito species used in the experiment are adults of Aedes albopictus.

This mosquito was collected in July 2014 at the entrance level elementary school of Kyoseong - gun, Jeollanam - do. Collecting method was collected from the tires and bucket around the collection site using mosquito larvae.

In order to secure an experimental mosquito,

① Collected mosquito larvae were fed with water and food in a feeding room maintained at a temperature of 27 ± 2 ° C and a humidity of 55 ± 5%.

② Feeding of mosquito larvae The finely pulverized pig feed was dissolved in water and given an appropriate amount according to the larval stage.

③ The larvae poured in the larvae were selected every day and placed in the adult cage so that they became alienated adults. To the alienated adults, 8% sugar water was soaked in cotton and fed to the food.

④ Adults give enough mating time for about one week, then put the mouse in a wire net to immigrate to the adult cage and feed the mice. The mice were swallowed every day for 3 days and replaced with new ones.

⑤ The mosquitoes that were sufficiently vomited were scattered about 4 ~ 5 days later, so on the third day, the scattering vessel was put in order to scatter the mosquito bites.

⑥ Egg eggs were stored at room temperature for about one week, and eggs and eggs were hatched in larvae. For the larvae hatched, the finely pulverized pig feed was dissolved in water and fed to the diet.

⑦ It was used in the avoidance experiment in which only the adult female of the mosquito repetitively raised as above was selected.

This breeding process of the white mosquito mosquito is shown in Fig. 2 (a) is an egg state, (b) is a larva, and (c) is an adult.

The process of avoidance experiment is as follows. A mosquito repellent experiment device for such an experiment is shown in Fig. In Fig. 3, (a) is a carbon dioxide gas container, (b) is a flow meter, and (c) is a chamber for experiments.

① Four 28 × 28.5 cm hardboards were prepared.

(2) Water-based paints containing the compound extracting water according to Examples 1 to 4 were applied on a hard board paper so that the ground surface could not be seen.

③ After thoroughly drying, hard coat paper painted with water-based paint was put on one side of the avoidance test kit, and 20 mosquito adult female mated sufficiently were put into the injection port.

④ 150 mL / min of carbon dioxide (CO ₂ ) gas was exposed to the surface where the hard board was installed, so that the mosquito was attracted to the surface painted with water-based paint.

⑤ The observation time of avoidance behavior of mosquitoes was 1 hour. The number of mosquitoes sitting on the wall was checked every 15 minutes from the first mosquito input.

⑥ The ventilated kit was ventilated sufficiently, wiped thoroughly with ethyl alcohol, and used for the retest.

⑦ The avoidance rate (%) calculation was calculated by the following equation (1).

Where C is the total number of mosquitoes used in the test and T is the number of mosquitoes sitting on the painted side.

The experimental results are shown in Tables 1 and 2 below.

Table 1 below shows the average avoidance rates for each of the aqueous paints containing the combined extract water according to Examples 1-4.

Experimental waterborne paints Average Avoidance Rate (%) ± SD Water-based paint Average Avoidance Rate (%) ± SD Example 1 98.3 ± 2.9 Example 3 75.0 + - 5.0 Example 2 78.3 ± 2.9 Example 4 58.3 ± 2.9

As can be seen in Table 1, the highest mosquito repulsion rate of 98.3% was obtained in the aqueous paint containing the compound extract water according to Example 1. In the water-based paint according to practical example 1, the plant refined oil smell was stronger than other water-based paints, and such a strong refined oil smell functioned to increase the avoidance effect of the mosquito.

Table 2 below shows the repellency effect duration for each of the aqueous paints containing the combined extract water according to Examples 1-4.

As can be seen from Table 1, the longest repelling effective duration of the water-based paint containing the compound extracting water according to Example 1 was shown.

4 shows the mosquito-sitting state of each of the water-based paints including the complex extraction water according to Examples 1 to 4 based on the 75-day time point with respect to the avoidance effect duration time. Fig. 4 (a) is a first embodiment, (b) is a second embodiment, (c) is a third embodiment, and (d) is a mosquito-sitting state of each of the water-based paints according to the fourth embodiment.

As a result of the experiment conducted for a total of 75 days at intervals of 15 days, the same repelling effect as that of the initial repelling effect was maintained even after 75 days in the water repellent coating according to Example 1. Based on the repetition duration, the average avoidance rate over 80 days after 75 days could be maintained.

Especially when the naturally fermented product is immersed in the sulfur water for 2 to 7 days by immersing it in the sulfuric water, the components (tannin, hyperperin, xanthoxylin, etc.) The duration of the sulfur component is doubled, so that the mosquito repellent effect can be maintained for a long period of time.
