Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor wax that keeps insects such as cockroaches away.

[0002]

2. Description of the Related Art Conventionally, various drugs have been developed and used for the purpose of eliminating insects such as cockroaches that live in the home. For example, various types of cockroach eliminating means are used, such as those that attract and capture cockroaches, or those that cause a cockroach to eat a drug and dehydrate it to kill it.

[0003]

However, this type of cockroach eliminating means is effective only when the cockroaches are attracted, and is not suitable for installation in a place where customers eat and drink, such as restaurants. That is, cockroaches are extremely uncomfortable for those who eat and drink, and it has been desired to provide a cockroach eliminating means that prevents such cockroaches from appearing in a certain area used for eating and drinking.

The present invention has been made in view of the above circumstances, and has a repellent effect of preventing cockroaches from approaching a certain area (for example, a place used for eating and drinking), so that the cockroaches enter the area. And eliminate all
The floor wax to be applied to the flooring material is provided with such a cockroach repellent effect, whereby the repellent effect of repelling the cockroach from a certain area can be obtained by the operation of applying the floor wax at regular intervals. The object is to provide a floor wax having extremely high workability and having a repellent effect.

[0005]

In order to achieve the above object, in the present invention, a wax component is added with a pyrethroid insect repellent component, and the wax component has an average molecular weight of 1,000 to 50,000, In addition, the insect repellent component is contained in a proportion of 0.02 to 5% by weight.

[0006]

According to the present invention, the pyrethroid insect repellent component is added to the wax component which is the main constituent of the floor wax, and the average molecular weight of the wax component is 1000 to 500.
It is confirmed that the insect repellent component is contained in an amount of 0.02 to 5% by weight and the cockroach is repelled at an extremely high repellent rate, and the high repellent rate can be maintained for a long period of time. Was confirmed. The average molecular weight of the wax component has an upper limit (50000) and a lower limit (10).
00) and are provided for the following reason. That is, when the molecular weight of the wax component becomes larger than the upper limit, the bleeding of the insect repellent component is hindered by the molecules constituting the resin which is the wax component, and when the molecular weight of the resin becomes smaller than the lower limit, the insect repellent is used. This is because the effect of bleeding the repellent component is obtained, but the thickness of the resin coating when applied on the floor surface becomes thin, and the performance as a floor wax (gloss, water resistance, etc.) decreases. Further, the upper limit (5% by weight) and the lower limit (0.02% by weight) are set for the content ratio of the insect repellent component for the following reason.
That is, the content ratio of the insect repellent component is because the ability to repel cockroaches is less than the lower limit,
On the other hand, when the amount exceeds the upper limit, the insect repellent component is less likely to be uniformly dispersed in the wax component, and the economical efficiency of the floor wax in price is reduced.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. The "floor wax having an insect repellent effect" according to the present invention is an acrylic resin-based or urethane resin-based wax component used as a wax component and a pyrethroid-based wax component as an insect repellent component. It is obtained by adding an additive such as water (adding an emulsifier in some cases) to the insect repellent component and mixing and stirring them with a stirrer.

The acrylic resin wax component is, for example, "trade name: 2-471 oligomer type (acrylic resin molecular weight 6000 to 8000)",
"Product name: 2-472 oligomer / polymer type (molecular weight of acrylic resin 100,000 or less)" is used,
Further, as insect repellent components, pyrethroid-based etofenprox (2- (p-ethoxyphenyl) -2-methylpropyl-3-phenoxybenzyl ether: trade name "trebon"), cyphenothrin ((RS) -α -Cyano-
3-phenoxybenzyl (1R) -cis / trans-chrysanthemate), permethrin (3-phenoxybenzyl-di-cis / trans-3 (2,2-dichlorovinyl)-
2,2 Dimethyl-1-cyclopropanecarboxylate:
Trade name "Exmin"), Allethrin (3-allyl-2-
Methylcyclopent-2-en-4-one-1-yl chrysanthemate) is used.

The resin as the wax component has an average molecular weight of 1,000 to 50,000, preferably 3,000 to 5,000.
It is preferable to use those of 20000. This is because when the average molecular weight of the resin becomes larger than 50,000, for example, the bleeding of the insect repellent component is hindered by the molecules constituting the resin, and when the average molecular weight of the resin becomes lower than 1,000, the insect repellent is prevented. This is because although the repellent component can be bleed, the thickness of the resin coating when applied on the floor becomes thin, and the performance as a floor wax (gloss, water resistance, etc.) decreases. Further, the insect repellent component is preferably mixed in a proportion of 0.02 to 5% by weight based on the total amount. This is because if it is less than 0.02% by weight, the ability to repel cockroaches becomes poor, and if it exceeds 5% by weight, the insect repellent component becomes difficult to be uniformly dispersed in the wax component, In addition, the economical efficiency of floor wax is also reduced. In the following description, a floor wax having an average molecular weight of the wax component of 1,000 to 50,000 and an insect repellent component of 0.02 to 5% by weight is referred to as a floor wax according to the present invention. To do.

A floor wax according to the present invention and a floor wax as a comparative example to be compared therewith will be described below with reference to the table of FIG. 1, and further with reference to FIG. 2, a floor wax according to the present invention will be described. The experimental data demonstrate that the wax is superior to that of the comparative example. In FIG. 1, among the floor waxes shown in sample numbers (1) to (10), those shown in sample numbers (1), (2), and (4) are floor waxes according to the present invention, and sample numbers (3 ), (5)
What is indicated by (10) to (10) is a floor wax as a comparative example compared with the present invention. The "acrylic resin emulsion" shown in the table of FIG.
The one adjusted to the weight% is used. Specific examples of the acrylic resin have already been described. As the “polyethylene wax emulsion”, an oxidized polyethylene wax emulsion, Allied-Seagram Co., AC-392,
A solids concentration of 40% by weight is used. "Leveling agent"
As the material, SMA resin 2625A, styrene-maleic acid copolymer resin, and solid component concentration of 15% by weight are used.
"Wetting agent" is available from Ciba Geigy, D-Dyne S-10
0, a fluorine-based surfactant and a solid content concentration of 25% by weight are used. Wacker-Silic as an "antifoaming agent"
Ones-Corp, SWS-211 is used. A 37% aqueous solution of formalin is used as the "preservative".

As can be seen from the composition table of FIG. 1 and FIG. 2 which summarizes the cockroach repellent performance and the floor wax performance corresponding to the sample numbers of FIG. 1, the average molecular weight of the resin as the wax component is The floor waxes (1), (2), and (4) according to the present invention in the range of 1,000 to 50,000 have evaluations of repellent rate of "1 (extremely good)" and "2 (good)", Also, the floor wax performance is "Good".
It was confirmed. Also, among these floor waxes,
The evaluation of the repellent rate of the floor wax (4) after one month is "2 (good)" because the wax component is a low molecular weight substance having a relatively low average molecular weight of 2000, It is considered that the insect repellent component (permethrin) was excessively bleeded, and as a result, the repellent effect of "1", which was considered to be extremely good, could not be maintained for a long period of one month. And from such experimental results, (1),
Since the floor waxes of (2) and (4) can maintain a high repellency rate of "1 (extremely good)" and "2 (good)" for at least one month, the floor waxes every one month. By applying the wax, the above-described high repellency can be continuously maintained.

Further, the floor wax of (3) given as a comparative example has a small average molecular weight of the resin of the wax component of 500 and the cockroach repelling effect is "1 (extremely good)", but the floor wax performance is " X (bad) "was confirmed. This is because, as described above, when the average molecular weight is lower than 1000, the thickness of the resin coating when applied on the floor becomes thin, and the performance as a floor wax (gloss, water resistance, etc.) decreases. is there. In addition, the floor waxes (6) and (7) given as comparative examples have a large average molecular weight of the resin of the wax component of 100,000 and have a floor wax performance of "good (good)", but have a repelling rate showing a cockroach repelling effect. It was confirmed that the evaluation was inferior as "3 (bad)" and "4 (extremely bad)". This is considered to be because, as described above, when the wax component has a large average molecular weight, the bleeding of the insect repellent component is hindered by the molecules of the wax component resin.

The floor wax (5) given as a comparative example has an average molecular weight of 100 as the wax component resin.
Although it is in the range of 0 to 50000, an emulsifier which is a plasticizer is added, and the evaluation of the repellent rate showing the cockroach repellent effect is "3 (bad)",
It was confirmed that "4 (extremely bad)" was inferior. That is, it is considered that the addition of the emulsifier causes the insect-repellent component to be trapped in the form of micelle, which makes it difficult to bleed. In addition, the floor waxes (8) to (10) given as comparative examples do not contain an insect repellent component,
As a result, the evaluation of the repellent rate showing the cockroach repellent effect is naturally "4 (extremely bad)".

Here, the method of measuring the repellent rate showing the cockroach repellent effect shown in FIG. 2 will be specifically described with reference to FIG. Reference numeral 1 in FIG. 3 denotes a test tank having a length of 40 cm, a width of 60 cm, and a height of 20 cm, and the treatment objects to be measured ((1) to (1 in FIG. 1) are provided at four locations in the test tank 1.
Floor tiles coated with wax of component 0) 2)
And a non-treated body (a floor tile which is a wax containing no insect repellent component and is coated with the same wax as the treated body 2), and the treated body 2 and the untreated body 3 are Shelters 4 and 5 for hiding cockroaches were placed on the upper surface. At the center of the test tank 1, food and water 6 for attracting cockroaches to the center were placed. The treated body 2 was applied to a homogeneous floor tile by coating each wax component twice, and used for the test after drying. Then, the processing body 2 thus wax-treated
In a test tank 1 in which the untreated body 3 and the untreated body 3 are arranged, 10 male and female adult German cockroaches, 10 larvae,
A total of 30 cockroaches were put in, and the repellency of the treated body 2 was examined immediately after the start of the test and one month after, depending on the number of the cockroaches present on the treated body 2.

By the test method as described above, the repellent rate of the treated body 2 against German cockroach was calculated as follows. That is, the repelling rate [%] = 100 × (A−B) / A, where A is the total number of cockroaches and B is the number of cockroaches on the treated body 2. The evaluation of the repellent rate is as follows. That is, when the repellent rate is 100 to 80%, “1
(Extremely good) "," 2 when the repellency rate is 80-60%
“Good”, “3 (bad)” when the repellency rate is 60 to 40%, and “4 (extremely bad)” when the repellency rate is 40% or less.

Next, the resin as the wax component of the "floor wax having an insect repellent effect" according to the present invention has an average molecular weight of 1,000 to 50,000, preferably 3,000 to 200.
The reason why it is set to 00 will be explained with reference to the graph of FIG.
The reason why the amount is set to 2 to 5% by weight will be described with reference to the graph of FIG.

<< Regarding the Graph of FIG. 4 >> The repellent ratio was tested when the molecular weight of the wax component was changed while the weight% of the acrylic wax component, the repellent component and other components were kept constant. That is, the relationship between the molecular weight and the repellency was investigated for various acrylic waxes having different molecular weights. As a result, as can be seen by referring to the graph, the repellency is as high as 80% or more in the molecular weight range of 1000 to 50,000, and the molecular weight of 3 is 3%.
It was confirmed that in the range of 000 to 20,000, the repelling rate was 90% or more, which was particularly high. In this test, etofenprox was used as an insect repellent component, and from the start of the test,
The repellency rate after one month was plotted. Further, in this test, etofenprox was used as the insect repellent component, but it was confirmed that the same results as the graph of FIG. 4 were obtained even if other insect repellent components such as cyphenothrin and allethrin were used. ing.

<< Regarding the Graph of FIG. 5 >> Etofenprox was used as an insect repellent component, and the repellent rate was tested when the weight% of this etofenprox was changed. That is, the relationship between the weight% of the insect repellent component and the repellent rate was investigated for various waxes containing different weight% of the insect repellent component. As a result, as can be seen from the graph, it was confirmed that the floor wax having an insect repellent component of 0.02% by weight or more has a high repelling rate of 80% or more. In this test, the repellency rate when one month has passed from the start of the test was plotted. Further, although etofenprox was used as the insect repellent component in this test, it was confirmed that the same results as the graph of FIG. 5 were obtained even if other insect repellent components such as cyphenothrin and allethrin were used. There is. Further, although an acrylic wax having a molecular weight of 20,000 was used as a wax component, it has been confirmed that similar results to those of the graph of FIG. 5 can be obtained for acrylic waxes having other molecular weights (molecular weight of 1000 to 50000). .
Further, it has been confirmed that the repellent rate gradually increases until the insect repellent component reaches 5% by weight, but thereafter tends to be constant or lower.

[0019]

As is apparent from the above description, according to the present invention, the main wax component of the floor wax is
Repelling cockroaches at an extremely high repelling rate by adding a pyrethroid insect repellent component, and by setting the average molecular weight of the wax component to 1,000 to 50,000 and the insect repellent component to a ratio of 0.02 to 5% by weight. It was confirmed that the repellent rate was maintained, and that the high repellent rate could be maintained for a long period of time. Then, by applying a floor wax having such a repellent effect to a certain area (for example, a place used for eating and drinking), entry of cockroaches into the area can be completely eliminated, and The effect of repelling such cockroaches from a certain area can be exerted by the wax coating operation which is usually performed, and thereby, extremely high workability can be obtained. Further, the floor wax having the repellent effect can maintain a high repellent rate for at least one month over a long period of time, and therefore, by applying the floor wax every month,
The effect that the high repellent rate can be maintained continuously is obtained.
