Description

DETAILED DESCRIPTION OF THE INVENTION The present invention involves impregnating colored paper with a composition prepared by blending piveronyl ptoxide or cinepirin 500 with paper rind to develop color, and easily determining the end point of use by the disappearance of color development. This invention relates to insect repellent paper for clothing, in which a verifiable insect repellent mat is enclosed in a plastic case or laminated paper or nonwoven fabric interior paper.

Conventionally, paradichlorobenzene, naphthalene, and shokutsuku have been commonly used in solid form as insect repellents for clothing. These three types of insect repellents for clothing are not completely satisfactory, such as odor problems, large amounts of use, the need to replace them with new ones every 3 to 4 months, and lack of insecticidal efficacy. It had various drawbacks, including a weak insect repellent effect. The present inventors have discovered the drawbacks of the above-mentioned clothing insect repellent, and also the flea, which has been increasing in recent years.
Lice, mites, beetles, wasps, and even flies,
As a result of research into chemicals that can also be used to control pests such as mosquitoes and cockroaches, we found that a clothing insect repellent that uses paper rind as a volatile agent is effective against clothing pests, unlike commercially available paradichlorbenzene, naphthalene, and shokutsuku formulations. It was found that it is suitable for the purpose because it has not only insect repellent effect but also insecticidal power, and does not have the strong odor or irritation characteristic of insect repellents such as paradichlorobenzene, naphthalene, and shokutsuku preparations. .

Furthermore, in order to control the volatilization amount of paper rin and to maintain the insect repellent effect for a long period of time, and to prevent chemical components from seeping into clothing, the paper rin-containing insect repellent mat is placed in a plastic case or with an interior made of laminated paper or non-woven fabric. He discovered that the method of packaging in paper was extremely effective, and filed a patent application in 15940Ji+.

However, paper thin is a liquid, and insect repellent mats impregnated with it have the disadvantage that it is difficult to determine the end point of use, such as when crystals of valadiclorbenzene or naphthalene disappear.

Therefore, the present inventors applied the principle of water brush paper and continued intensive research. As a result, we used colored paper instead of the conventional pulp mat and applied Babasrin Niviveronyl ptoxide or Cinepirin 500. The present invention was completed by discovering that when the composition is impregnated to develop color and used as an insect repellent mat, the end point of use can be easily confirmed by the disappearance of color after a certain period of time.

The colored paper used in the present invention includes base paper waste made from bulb or linter, a colored layer of any hue provided on the base paper layer and the surface, and a low refractive index pigment provided on the colored layer, It consists of a ground color layer that has appropriate oil resistance and oil permeability and has a different hue from the colored layer. The hue of the colored layer develops due to the change in ratio. As the concentration in the colored paper, particularly in the ground color layer, decreases due to volatilization of the chemicals, the color fades as it cools slowly, and eventually returns to the hue of the ground color layer.

Piperonyl ptoxide and cinepirin 500 used in the present invention are for household use as a synergist for pyrethroids,
It is a compound widely used in agricultural applications, and also plays a role as a volatilization regulator for the active ingredient, ie, pyrethroid, in the formulation of electric mosquito repellent mats. These solid compounds are structurally completely different from the insect repellent ingredient paper rin (higher fatty acid ester compound) for clothing used in the present invention, and it was not initially expected that they would have the same coloring ability as paper rin. After practical testing of various types of formulations, the inventors have found that these compounds are most suitable in combination with Paperthrin.

In carrying out the present invention, it is preferable to appropriately determine the type of biperonyl ptoxide or puinevirin 500 to be used, the amount of application, or the blending ratio with paper thrin, depending on the usage conditions and efficacy duration conditions of the insect repellent mat.

In this case, biveronyl ptoxide or cynevirin 5
The degree of color development due to the refractive index of 0.00, volatility, etc. are taken into consideration.For example, the minimum necessary amount of piperonyl ptoxide or cinepirin 500, which has low volatility, is applied for color development, and then paper rinse is used as an ointment, and insect repellent is used. This is an extremely useful and practical invention in that it provides a method for more reliably indicating the end point.In addition to the paper-thin-containing insect repellent mat, there is also a method of providing an indicator in which a small piece of colored paper is impregnated with a chemical solution. However, the insect repellent for clothing of the present invention has the advantage that it is easy to understand because the entire product is colored, and there is no need to consider the difference in volatility between the insect repellent mat and the colored paper.

The insect repellent mat of the present invention is impregnated with a pyrethroid compound that has extremely low toxicity to humans and livestock, and does not have the odor or irritation of radichlorobenzene, naphthalene or shock absorbers. It can be used safely at home starting from 7. In order to stabilize the drug, BHT is added to these.

It is also useful to add antioxidants such as DBH and BHA, and to add flavoring agents to add aromatic properties.

゛In addition, there are plastic booths containing insect repellent mats,
Lamination applied to interior paper or piveronyl butoxide or cinepirin 500 in paper string
The method of printing and applying the composition containing the above to colored paper is based on conventionally known resin processing, laminating, and chemical processing methods, and does not require any new equipment, and conventional equipment can be used for multiple purposes. It is beneficial.

Next, the present invention will be explained in detail with reference to Examples.

Example 1 Colored paper with an area of 48 ffl (6×8σ) was impregnated with various chemicals to obtain an insect repellent mat, which was enclosed in a plastic booth and hung in a dresser. After 8 months, the residual amount of the drug in the insect repellent mat and the degree of color development of the indicator were examined, and the results were as follows.

In this test, the minimum amount required for indicator color development is paperthrin, biperonyl butoxide, and cinepirin 5.
00 was about 3 QF/crd.

In the case of paper rinse alone (Test 1), the color had already faded after 8 months, and it was thought that a higher concentration of paper rinse would be necessary. Undesirable.

On the other hand, when piperonyl ptoxide or cynevirin 500, which has lower volatility than paperthrin, was used in combination (tests 2 to 5), the total amount of volatilization was suppressed, and test 3.
In cases 5 and 5, the color development was controlled to the extent that it disappeared after 8 months.

In other words, due to the low volatility of biperonyl ptoxide or synehirin 500, the minimum required amount of these agents for color development was added, and an appropriate amount of paper rinse (the amount of volatilization for 8 months) was added to the mixture (Tests 3 and 5). ) has been found to be very practical and advantageous because it allows more reliable control of color development and reduces the amount of expensive paper rinse.

Example 2゜The chemicals shown in the table below and DBH3rnq were applied to colored paper made by Palprinter with an area of 11 m (2.2X 5.0σ) and a thickness of 0.3 marks.
An insect repellent mat is obtained by impregnating 1 rng of fragrance, and this is
It was packaged in P20μ laminated inner paper. Five pieces of muslin cloth were stacked and stored in one drawer of approximately 501, and five pieces of the clothing insect repellent of the present invention were placed between each of them. Immediately after the start of the test and after 8 months, the degree of color development of the indicator was examined, and 60 adult burr larvae were placed on the third and fifth muslin cloths from the bottom, and the number of deaths was observed over time. As a result, the insect repellent for clothing of the present invention (insect repellent mats 1 to 4) was sufficiently effective even after 8 months, and the indicator color development was controlled.

In addition, regardless of the material of the laminated film, 15~
For example, PE of 60,11.

Similar results were obtained when processing both one and both sides of PP. Also,
Clothes pests such as burrs, carp moths, and cutworms can be found in drawers, wardrobe boxes, and even storage areas for seasonings in the kitchen.
It was also effective in controlling sanitary pests such as fleas, lice, and mites.
