The present invention relates to an insect repellent antimicrobial composition that can be added to the upper layer of vinyl flooring used in homes and at the same time have the effect of insect repellent and antibacterial. That is, in the present invention, when a predetermined amount is added to the upper layer of the vinyl flooring material (UV paint layer), the upper layer of the flooring material has an insect repellent antibacterial effect, and the insect repellent effect against insects such as cockroaches and ticks is effective It appears, on the other hand it is also a bactericidal power against bacteria and mold caused by a variety of causes to be a sanitary flooring as a whole, and relates to the insect repellent antibacterial composition for vinyl flooring can be long-lasting effect.

As living standards improve these days, consumers' preferences and demands for insect repellent and antibacterial treatment are on the rise. Accordingly, products that are being treated with antibacterial products such as various household goods and children's products are increasing. On the other hand, the demand for insect repellent treatment is increasing in the area mainly associated with the kitchen, that is, damage to the insects, as well as damage caused by bacteria, fungi, such as sinks and sanitary sheets (sheets).

Apart from household and kitchenware, vinyl flooring, which is mainly installed in living rooms and kitchens, is not only in the past, but also in terms of hygiene. Since flooring is the most contacted part of life, the necessity of insect repellent treatment is increasing to prevent not only contamination of bacteria and mold, but also damage caused by pests such as cockroaches and ticks.

Therefore, the present invention has an object to provide a flooring insect repellent composition suitable for the above uses. Another object of the present invention to provide a method for producing a PVC flooring using the composition.

The composition of the present invention for achieving the above object is 1-ethynyl-2-methyl-2-pentenyl-2,2-dimethyl-3- (2-methyl-1-propenyl) = cyclopropane-carboxylate (1-ethynyl-2-methyl-2-pentenyl-2,2-dimethyl-3- (2-methyl-1-propenyl) = cyclopropane-carboxylate) and 3-phenoxybenzyl (+-)-3- (2 3-phenoxybenzyl (+-)-3- (2,2-dichlorovinyl) -2,2-dimethylcyclopropane-carboxylate) is from 5:95 to 2-dichlorovinyl) -2,2-dimethylcyclopropane-carboxylate.

The method of the present invention for achieving the above another object comprises the addition of 1.0 to 5.0% by weight of the insect repellent antimicrobial composition to the UV paint of the PVC flooring.

Hereinafter, the configuration of the present invention and its operation principle will be described.

1. Insect Repellent

The composition of the insect repellent fungicide is composed of a mixture of substances showing insect repellent effect and substances showing antibacterial effect. First of all, the insect repellent effect is that when processed into UV paint, which is the upper layer of vinyl flooring, for example, when a cockroach comes into contact with an insect repellent material, the cockroach detects or avoids the cockroach or detects a minute smell that humans cannot feel. By avoiding this, the effect of avoiding insect repellent appears. In the present invention, such a substance is 1-ethyl-2-methyl-2-pentenyl-2,2-dimethyl-3- (2-methyl-1-propenyl) = cyclopropanecarboxylate and 3-phenoxybenzyl ( +-)-3- (2,2-dichlorovinyl) -2,2-dimethylcyclopropanecarboxylate was chosen, which is a pyrethroid-based material. The function of this mixture is, as mentioned above, to avoid insect repellent effects, but may also weaken some activity against pests.

2. Antibacterial effect

The next feature of this insect repellent is the antibacterial effect. Vinyl flooring is a lot of microorganisms are generated due to a lot of contact with people and objects and also due to various food residues and carcasses of invisible insects. Microorganisms, such as mold and bacteria, the surface of the flooring material is often in contact with the human body, if contaminated by these microorganisms will adversely affect the health of the human body.

Substances exhibiting antibacterial effects of the present invention include 2- (4-thiazolyl) -benzimidazole, 3-iodine-2-propargyl-butylcarbamate and 2-n-octyl-4-isothiazoline-3- It is made on and all are suitable antiseptics for paints. These substances are cured together with the paint and are sterilized upon contact with microorganisms. The first two fungicides are mainly for fungi, and the last one is mainly for bacteria, and a combination of them is for fungi and bacteria. In addition, the feature of these combinations is that the antimicrobial activity is greater than the arithmetic sum of the inherent antimicrobial power of each antimicrobial agent. That is, unexpected synergistic effect of antimicrobial activity appears.

3. Synergistic effect of insect repellent

A big feature of the present invention is that there is a synergistic effect of the insecticide and the antibacterial effect more than the arithmetic sum of the effects of the insecticide and the insecticide component, respectively.

When the insecticide is mixed with the insecticide, the insecticide exhibits synergy among its constituent antimicrobial components, which act as a kind of adjuvant or catalyst when each of the relative components has its own function. It is thought to be.

Hereinafter, the configuration of the present invention in more detail.

Insect repellent composition of the present invention is 1-ethynyl-2-methyl-2-pentenyl-2,2-dimethyl-3- (2-methyl-1-propenyl) = cyclopropane-carboxylate and 3- Insect repellent mixture in which phenoxybenzyl (+-)-3- (2,2-dichlorovinyl) -2,2-dimethylcyclopropane-carboxylate is mixed at a weight ratio of 5:95 to 45:55, and 2- ( 4-thiazolyl) -benzimidazole 0.5-1.5 parts by weight, 3-iodine-2-propargyl-butylcarbamate 5.0-20.0 parts by weight, 2-n-octyl-4-isothiazolin-3-one 7.5 And an antibacterial solution mixture comprising 55 to 90 parts by weight of one or more solvents selected from the group consisting of ˜25.0 parts by weight and propylene glycol monomethyl ether, toluene, methyl ethyl ketone and methyl isobutyl ketone. The solution is mixed at a weight ratio of 1.5 to 3.0: 1. As the solution used for the antibacterial solution mixture, propylene glycol monomethyl ether is most preferred.

The insecticide composition of the present invention can be added to the UV paint layer, which is the upper layer of the vinyl flooring material, and can be used by being added to the PVC layer, which is the middle layer and the lower layer of the vinyl flooring material.

Hereinafter, the configuration of the present invention will be described in more detail with reference to Examples, but the scope of the present invention is not limited to the following Examples.

Example 1

Preparation of Insect Repellent Stock Solution for Adding Upper Layer (UV Coating) of Vinyl Flooring

end. Insect repellent 1-ethynyl-2-methyl-2-pentenyl-2,2-dimethyl-3- (2-methyl-1-propenyl) = cyclopropane-carboxylate and 3-phenoxybenzyl (+- ) -3- (2,2-dichlorovinyl) -2,2-dimethylcyclopropane-carboxylate is mixed well in a weight ratio of 10:90. The following antibacterial ingredients were 1.5% by weight of 2- (4-thiazolyl) -benzimidazole (A), 8.0% by weight of 3-iodine-2-propargyl-butylcarbamate (B) and 2-n-octyl 15 wt% of -4-isothiazolin-3-one (C) are respectively mixed, and dissolved therein using a solvent, propylene glycol monomethyl ether, and adjusted to a volume of 100%. Insect repellent components and antibacterial components 66.7% by weight: 33.3% by weight of the mixture is mixed well to prepare an insect repellent stock solution.

I. The prepared insecticide antibacterial solution is added to the UV paint, which is the upper layer of the vinyl flooring material, and mixed well to prepare a UV paint having an insect repellent bactericidal function.

Example 2 Insect Repellent Effect

The insect repellent effect of the insect repellent is determined by the insect repellent avoidance rate. This insect repellent is effective to avoid home pests such as cockroaches. Insect repellent stock solution was prepared by mixing the insect repellent and antibacterial components in a 2.0: 1. Next, cut the flooring test specimen treated with the insect repellent 3.0% by weight to 7 × 7 cm at the bottom of the plastic container about 35 × 25 × 20 cm, and place the floor test specimen without the insect repellent treatment on the paint. Put on. Next, the four legs were made to allow free access to the cockroach on the slope of the wooden board cut to a size of 7 × 7 cm, and the roof was placed on the test piece so that the cockroach could hide. With adequate water and food, 25 cockroaches were placed in a container to count the number of cockroaches that could enter the hideout. This test was repeated three times in consideration of the error to obtain an average value. The results were as follows.

Evasion rate was calculated by the following formula.

Evasion rate (%) = (cockroaches of 1-treated specimens / roaches of untreated specimens) x 100

The calculation was performed as follows.

Evasion = (1-7 / 68) × 100 = 89.7%

Excellent insect repellent effect was obtained as described above.

Example 3

Antibacterial efficacy test (bacteria)

Using the insect repellent fungus prepared in Example 1, the processed flooring material was cut into small pieces to prepare about 3.5 g and placed in 70 ml of bacterial culture medium (four preparations). Two kinds of bacteria (Klebsiella pneumoniae, Staphylococcus aureus) previously cultured therein were inoculated in 5 ml of each of the prepared culture solutions, followed by shaking culture at 37 ° C and 250 rpm. After 20 hours, the bacterial reduction rate was counted by counting the number of bacteria grown in the treated and untreated samples, and the antibacterial effect was evaluated.

As a result of the test, the bactericidal rate of about 99% was obtained for the bacterium to obtain excellent antibacterial effect.

Example 4

Antibacterial test (fungus)

This time, a fungus test on the fungus was carried out. Samples prepared and cured under the same conditions as in the above experiments were prepared. This sample and a sample coated with only UV paint (without insecticide) were cut into circles each having a diameter of 4 cm, placed in the center of an empty flat plate so that the sample was sufficiently submerged. 72 hours of incubation was performed to observe how the antimicrobial component of the UV paint layer affected the growth of mold.

Note) †††: Full growth,-: No growth

Example 5

Synergistic Effect of Insect Repellent Components in Insect Repellent Solution

end. In order to determine the synergistic effect of the antimicrobial component prepared in Example 1 was performed as follows. First, MIC values were obtained for the fungus Aspergillus niger for each antimicrobial agent.

I. Next, 2- (4-thiazolyl) -benzimidazole (A) and 3-iodine-2-propargyl-butyl carbamate (B), and 2-n-octyl-4-isothiazoline-3- We obtained MIC when we used on (C) together. The following formula holds.

FIC index = (a / a₁ + b / b₁ + c / c₁): fractional concentration index

a₁: MIC at the time of use of A antibacterial agent alone

b₁: MIC when using B antibacterial agent alone

c₁: MIC when using C antibacterial agent alone

a: MIC of A when A + B + C

B: MIC of B when A + B + C

C: MIC of C when A + B + C

If, FIC index> 1: Antagonism

FIC index 〈1: Synergy

All. The values obtained in k and b are shown in Table 4 below.

These values above b. Substituting in an expression,

FIC = 2/10 + 2/8 + 0.5 / 2 = 0.7 <1

This result indicates a synergistic effect.

As shown in the above experimental results, the antibacterial components showed synergistic effects among the constituent antimicrobials.

Example 6

Synergistic Effects of Insect Repellent and Antiseptic Components

end. This time, we examined the synergy between insecticides and insecticides. It can be said that the insect repellent is compared with the insect repellent effect when the insect repellent treats the insect repellent at the same concentration but contains some of the insect repellent.

I. Only the insect repellent prepared in Example 2 was added to the 1.0% paint to prepare a sample processed on the vinyl flooring material and the insecticide: 1.5% by weight of the raw material mixed with the insecticide 1: 0.5 mixed stock solution was prepared. In other words, the amount of the insect repellent was the same in both cases.

All. Next, an experiment was performed to find the insect repellent evasion rate. The method is the same as in Example 2. Repeated three times the average value of the insect repellent escape rate was as shown in Tables 5 and 6.

Evasion = (1-14 / 61) × 100 = 77.0%

Evasion rate = (1-10 / 65) × 100 = 84.6%

Comparing the above two cases, the insect repellent evasion rate increased by about 7.6% from 77.0% to 84.6%. That is, the synergistic effect of the insect repellent effect by the mixing of the antiseptics appeared.

EXAMPLES 7, 8, and 9

Except that the addition amount to the ingredients described in Table 6 was carried out in the same manner as in Example 3 to prepare an insect repellent antiseptic composition and the same as in Example 3 was carried out in the antibacterial efficacy test described in Table 7.

As described above, the composition according to the present invention is a combination of compounds having antibacterial activity against fungi or bacteria is effective in showing the antimicrobial activity of the arithmetic sum of the intrinsic antimicrobial power of each antimicrobial agent.
