CONSTITUTION:The paper-like material 1 is composed of the oil-permeable substrate material 2 having substrate color and the oil-permeable base-colored layer 3 having low refractive index and formed on the surface of the substrate material 2. A transparent or semitransparent covering material 4l impermeable or semipermeable to the vapor of a vermin-repelling liquid is laminated to the surface of the base-colored layer 3 to obtain a paper-like product A. The paper-like material 1 is impregnated with any oily vermin-repellent liquid vaporizing at normal temperature, to obtain the titled vermin-repelling material. The base-colored layer 3 having low refractive index turns transparent by the vermin-repelling liquid impregnated from the substrate material 2 to the base-colored layer 3, and the surface of the paper-like product A exhibits the substrate color of the substrate material 2. When the vermin-repellent is dissipated from the back surface of the substrate material 2, the base-colored layer 3 turns opaque, and the color of the base-colored layer 3 can be seen through the covering material.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an insect repellent material that also functions as an insect repellent indicator, which integrally maintains the original insect repellent function and the function as an insect repellent indicator. By covering with a cover material, it is possible to use it safely and in a variety of ways, and also to ensure a reliable display function.

[Conventional technology]

Recently, in place of the conventional insect repellent material that is made by solidifying the volatile solid insect repellent itself in a fixed form, insect repellent materials that have a synthetic resin material containing an insect repellent agent that is volatile at room temperature have become popular. It has come to be mass-produced due to its advantages in processability and usability. In addition, insect repellent materials that also function as insect repellent indicators are also made, with an integral part of the insect repellent display section.
Such insect repellent materials have a structure in which the base material is a paper-like material that exhibits remarkable discoloration depending on the volatilization amount of the insect repellent liquid agent contained therein.

[Problem that the invention seeks to solve]

Among the conventional insect repellent materials mentioned above, the former does not show any change in the synthetic resin material that determines its appearance when used, and its insect repellent ability cannot be easily confirmed. Insect repellent labeling simply indicated the expiration date in advance. In addition, in the latter case, since the surface on the base material that functions as an indicator is also the dissipation surface for the volatilized gas of the contained insect repellent liquid, there is actually a difference between the remaining amount of the insect repellent liquid and its insect repellent ability display. There have been concerns that the display may become inaccurate due to misalignment or leakage or leaching of the insect repellent solution to the surface area along the display function surface, and in some cases, it may be difficult to use.

[Means for Solving the Problems] The present invention employs the following configuration as an insect repellent material that also functions as an insect repellent indicator to eliminate the above-mentioned drawbacks.

That is, an oil-permeable substrate material 2 exhibiting a base color and an oil-permeable base color layer 3 with a low refractive index formed on one side of this substrate material 2.
A transparent or semi-transparent cover material 4 which is impermeable to semi-permeable to the volatilized gas of the insect repellent liquid agent described below is provided on the ground color layer 3 surface of the paper material 1. are laminated to form a paper-like material A, and one portion of the paper-like material of the paper-like material A contains an oil-based insect repellent solution that is volatile at room temperature.

In the present invention, the above-mentioned insect repellent liquid agent is a liquid agent that is liquid at room temperature, especially oily, and exhibits volatility enough to exhibit an effective insect repellent effect at room temperature, such as o-(2',...
2-dichlorovinyl)0゜0-dimethylphosphate, 4-methyl-4-hebuten-1-yn-3-yl d-
cis, trans-chrysanthemate, 2,3,4,5.
6-Pentafluorobenzyl 2,2-'; Methyl-3-
(2', 2'-dichloroethynyl)cyclopropane-1-carboxylate and the like can be mentioned.

[For production]

The insect repellent material that also serves as an insect repellent indicator according to the present invention having the above-mentioned structural characteristics has the following effects.

The insect repellent liquid contained therein is initially accommodated and held in the substrate material 2 based on its oil permeability, and the insect repellent liquid permeates directly from the surface of this substrate material 2 into the oil permeable ground color layer 3. . At this time, the ground color layer 3 is made transparent due to its low refractive index, and the paper-like material A side exhibits the ground color on the substrate material 2 side via the transparent or translucent cover material 4.

When used next time, most of the insect repellent liquid contained in the paper material A is volatilized and released from the back surface of the substrate material 2 due to the shielding properties based on the impermeability or semi-permeability of the cover material 4. . As the insect repellent solution is volatilized and released, the contained insect repellent solution gradually disappears due to its sustained release properties due to its oily nature, and the ground color layer 3 eventually becomes opaque. As a result, in the paper-like body 1, the cover material 4
The ground color of the ground color layer 3 is exhibited through the ground color layer 3.

Such a change in color tone on one side of the paper-like material is caused by the contained insect repellent liquid being volatilized and released from the back surface of the substrate material 1 as described above, so that the transparent state of the ground color layer 3 is caused by the insect repellent liquid. Considering that it depends only on the presence of the chemical solution and not on the presence of its volatilized gas, the time point at which the color tone changes coincides with the time point at which the contained insect repellent solution disappears, and the display function is extremely accurate.

〔Example〕

Next, the present invention will be explained in detail. Example 1 shown in Figure 1
1 is a paper-like material 1 with a ground color layer 3 formed on one side of a substrate material 2.
A paper-like material A having a structure in which a cover material 4 is further laminated on three sides of the ground color layer is used, and one portion of the paper-like material contains the above-mentioned room temperature volatile oil-based insect repellent liquid. This is an insect repellent material that doubles as an insect repellent indicator.

In this embodiment, the substrate material 2 is made of paper, paperboard, paper mixed with synthetic fibers, nonwoven fabric, felt-like fabric, or fabric-like inorganic fiber, for example, in the light of the above-mentioned functions.
It can be used by cutting it into a size of 0sn and 28mm in width. Further, as the ground color layer 3, for example, organic substances such as amorphous silica, kaolin, calcium carbonate, or pulp powder can be used as a white colorant, and a binder for fixing such a colorant to the two surfaces of the substrate material. Appropriate oil permeability can be set by appropriately selecting the mixing ratio of . As this binder, vinyl acetate, EVA, NBR
l SBR, acrylic and other latexes can be used; in this case, the coating solution is prepared at a mixing ratio of the coloring agent and the binder of 1:0.1 to 3 (parts by weight), and then applied. e, the amount is 4~1s o g'i
(dry) is appropriate. In this case, if it is too small, the color development as a ground color will be poor, and if it is too large, the change in color will be delayed.

+ Muff', :, h As the bar material 4, a volatile gas impermeable material such as polyester, K coated polypropylene, and various laminated materials, or a volatile gas semipermeable material such as polyethylene, polypropylene, polyvinyl acetate, etc. is used as a film. It can be applied in the form of a shape or a sorted shape, and is laminated on the ground color layer 3 surface of the paper-like material 1 described above by applying a normal lamination method.

The above-mentioned insect repellent liquid agent is contained in the paper-like material A, which is made up of various parts of the paper-like material A by appropriately selecting various materials as described above, by applying a general impregnation or injection method such as a dipping method.

In the insect repellent material that also functions as an insect repellent indicator and is constructed in this way, for example, the paper material 1 (vertical length jOwm
, width 28 shoes, thickness Q, 3 rmn) in the above-mentioned insect repellent solution for about 3 hours and sufficiently impregnated with the insect repellent solution. Although it was accommodated in the plate material 2, it also penetrated into the ground color layer 3 and became transparent, and the surface of the paper material 1 exhibited the ground color of the substrate material 2 through the cover material 4. At this time, even when the above-mentioned volatilized gas semi-permeable material was used as the cover material, the insect repellent solution did not leak or seep out from its surface, and the volatilized gas released was extremely small. When this insect repellent material that also serves as an insect repellent indicator is placed indoors in an upright position (as shown in Figures 10 and 11 as described later), most of the volatilized gas from the insect repellent solution contained in the insect repellent liquid is absorbed by the substrate material. It was released in a sustained manner from the back side of 2, and the coloration in terms of its display function was maintained as it was for about 6 months, and it also exhibited effective insect repellent effects.

Thereafter, as the insect repellent effect disappeared, a rapid change in the displayed color was observed, and the color changed to that of the ground color layer 3. In this way, the volatilization and release of the contained insect repellent liquid agent is mostly limited to the back surface of the substrate material 2, and the time of its disappearance coincides with the time of display operation. In other words, it can be confirmed that the insect repellent ability display is extremely accurate.

Next, as for the base color of the substrate material 2, the color scheme of the substrate material 2 itself can be applied as is, as in the above-mentioned Example 1. It is desirable that there is a large hue difference between the changes in coloration to achieve this effect.For example, if the coloring of the ground color layer 3 and the base color of the substrate material 2 are "white and black," or "black and yellow," ,
It is appropriate to use a combination of colors such as "red and blue".

The color tone configuration of the above combination is realized by the second embodiment shown in FIG. 2 in the present invention. That is, a paper-like material 1 has a base colored layer 2a formed by applying an oil-permeable colorant onto the surface of the substrate material 2.
This is the case where the paper-like material A' consisting of ' is applied. This configuration using the paper-like material A' makes it possible to always obtain a base color of a hue selected corresponding to the hue of the base color layer 3 for the various substrate materials 2 described above. The base colored layer 2a is coated with a prepared liquid prepared by appropriately mixing a colorant such as a pigment or dye with the above-mentioned binder, preferably at a mixing ratio of 1:0.1 to 3 (parts by weight). Accordingly, it can be formed to have the necessary coloration and appropriate oil permeability.

Next, in the third embodiment of the present invention shown in FIG.
This is an insect repellent material which also serves as an insect repellent indicator, to which a paper-like material B having a structure in which a sorted porous material such as a sponge is fixed as a separation material 5 on the back surface of the paper material B is used. In this paper-like body B, the separation material 5 covers the volatilized gas emitting surface of the substrate material 2, and for example, the separation material 5 is attached to an object to be insect-proofed such as clothing with the display function surface of the cover material 4 facing upward. It becomes possible to use it in the following manner.

Next, FIGS. 4 and 5 show a configuration in which the display function section functions to display a pattern as a fourth embodiment of the present invention, and the paper-like material C is the paper-like material 1. The paper-like material 1a has a structure in which a pattern layer 3a of an oil-impermeable material is formed in a line or band shape on the ground color layer 3 portion. This paper-like material C is a pattern layer 3a.
Since the transparent state due to the insect repellent liquid agent contained is obtained only in the ground color layer 3 excluding the part, the appearance of the formed pattern depends on the base color of the substrate material 2 and the color tone based on the coloring of the ground color layer 3. It becomes possible to confirm the appearance or disappearance from the outside.

The pattern display function of the above-mentioned insect repellent material that also functions as an insect repellent indicator according to the present invention is achieved by the paper-like material C' of Example 5 shown in FIG. 6 and the paper-like material C' of Example 6 shown in FIG. The paper-like material C' has a structure in which the entire upper part of the pattern layer 3b is covered with the ground color layer 3; The pattern layer 2b is formed on the base colored layer 2a portion of the paper material A'. When this paper-like material σ, is applied, it functions so that the pattern formed by the pattern layer 2b completely disappears when the ground color layer 3 becomes opaque due to the disappearance of the insect repellent liquid contained therein. Therefore, the display becomes extremely noticeable.

The pattern layers 3b and 2b described above are formed using an oil-impermeable forming material such as an acrylic resin, a synthetic resin such as polypropylene, or a latex such as SBR, by applying a coating method or various printing methods.

Next, Example 7 of the present invention related to another pattern display configuration
are shown in FIGS. 8 and 9. The paper-like body in this Example 7 has a structure in which a pattern layer 4a is formed on the bonding surface of the cover material 4. Note that 4' in the figure indicates a partially peeled cover material.

Even when this paper-like body is applied, the pattern formed by the pattern layer 4a is made to appear or disappear depending on the color tone based on the base color of the substrate material and the coloring of the base color layer 3. Is possible.

The pattern layer 4a of this paper-like material is not particularly limited in its material, and a wide variety of forming materials can be applied, and it can be easily obtained by a simple forming method. Ground color layer 3 or base colored layer 2a in paper-like material
Compared to the paper-like bodies C1σ, C'', which are formed in connection with the present invention, it is possible to obtain an extremely simple structure and a more complex pattern structure.

In addition, the structure of the pattern display on the paper-like material is as follows.
By adopting a, 1b or 1'a, it is possible to obtain two upper and lower pattern layers, and the display pattern created by the combination of these pattern layers exhibits the display function of a variety of pattern shapes that change in a complex manner. Also possible.

Next, FIGS. 10 and 11 show specific examples of how the above-mentioned insect repellent material serving as an insect repellent indicator according to the present invention is used.

In this usage example, a paper-like insect repellent material that also functions as an insect repellent indicator is housed in a container 10 that is formed into a picture frame shape and has a front opening 11, with its display function side positioned in the direction of the front opening 11. ing.

In this storage form, the display function surface of the insect repellent material that also serves as an insect repellent indicator is exposed through the front opening 11, and the cover material 4 on the paper-like material appropriately shields the volatilized gas of the insect repellent liquid contained therein. It functions to ensure safety during its use. In addition, if a display configuration that provides the various patterns described above as a display configuration that can be seen through the front opening 11 through the cover material 4 is adopted, it is possible to create an excellent value as an interior decoration item.

Further, on the container 10, a diffusion hole 12... and a diffusion hole 13... are formed on the side wall surface of the container 10, and a diffusion hole 13... to effectively exert its insect repellent function. Also, container 1
A support portion 14 provided on the outer surface of the rear wall of the vehicle 0 allows the insect repellent material that also serves as an insect repellent indicator to be installed at a position as required.
