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]

In recent years, instead of the traditional insect repellent materials made by solidifying volatile solid insect repellents into a fixed shape, insect repellent materials containing synthetic resin materials that are volatile at room temperature have improved in terms of processability and utilization. It has come to be mass-produced due to its sexual advantages. 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. A structure is adopted in which the base material is a paper-like material that exhibits remarkable discoloration depending on the amount.

[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. The insect repellent ability label 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 the insect repellent solution may leak or seep onto the surface along the display function surface, and in some cases may be difficult to use.

[Means for solving 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, it has a paper-like material 1 consisting of an oil liquid permeable substrate material 2 exhibiting a base color and an oil liquid permeable base color layer 3 having 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 described below is laminated on the ground color layer 3 surface of this paper material 1.
This paper-like material A is characterized by a structure in which one portion of the paper-like material 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-dichloro vinyl) o,o-dimethyl phosphate, 4-methyl-4-hepten-1-yn-3-yl d-cis, trans-chrysanthemate, 2,3,4,5,6-pentafluorobenzyl 2, Examples include 2-dimethyl-3-(2',2'-dichloroethenyl)cyclopropane-1-carboxylate.

[Effect]

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 contained insect repellent liquid was initially mainly used for substrate material 2.
Based on its oil permeability, it is housed and held in the base material 2, and the insect repellent liquid permeates directly from the base material 2 surface 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-like material A is transferred to the substrate material 2 due to the shielding properties based on the impermeability or semi-permeability of the cover material 4.
It is released by volatilization from the back surface of the As the insect repellent solution is volatilized and released, the insect repellent liquid agent contained therein gradually disappears due to its oil-based sustained release properties, and the ground color layer 3 eventually becomes opaque. As a result, the paper material 1 exhibits the ground color of the ground color layer 3 through the cover material 4.

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 the transparent state of the ground color layer 3 is caused by the insect repellent. Considering that it depends only on the presence of the firing liquid and not on the presence of its volatile gas,
The time point at which the color tone changes coincides with the time point at which the contained insect repellent solution disappears, making the display function extremely accurate.

〔Example〕

Next, examples of the present invention will be described. Embodiment 1 shown in FIG. 1 has a paper material 1 having a ground color layer 3 formed on one side of a substrate material 2, and a paper material 1 having a structure in which a cover material 4 is further laminated on the ground color layer 3 surface. This is an insect repellent material which can also be used as an insect repellent indicator and is made by using Form A and having one portion of the paper material contain the above-described oil-based insect repellent solution that is volatile at room temperature.

In this embodiment, the substrate material 2 is made of paper, paperboard, paper mixed with synthetic fibers, nonwoven fabric, felt-like fabric, or cloth-like inorganic fiber, for example, with a size of 10 mm in length and 28 mm in width. It can be cut into pieces and used. In addition, as the ground color layer 3, for example, amorphous silica for white colorant,
Organic substances such as kaolin, calcium carbonate, or pulp powder can be applied, and appropriate oil permeability can be set by appropriately selecting the mixing ratio of the binder to fix such colorants to the two surfaces of the substrate material. be able to. As this binder, vinyl acetate,
EVA, NBR, SBR, acrylic and other latexes can be used, and in this case, the mixing ratio of the coloring agent and the binder is 1:0.1 to 3.
(parts by weight), and the appropriate amount of the coating liquid is 4 to 150 g/m ² (dry). 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.

Further, as the cover material 4, polyester, k
Volatile gas impermeable materials such as coated polypropylene and various laminated lumber, or polyethylene,
A volatile gas semi-permeable material such as polypropylene or polyvinyl acetate can be applied in the form of a film or sheet, and can be applied by a normal lamination method on the ground color layer 3 surface of the paper-like material 1 described above. is applied and laminated.

The insect repellent liquid agent is contained in the paper-like material A, each part of which is constructed 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 doubles as an insect repellent indicator and is constructed in this way, for example, a paper material 1 (length 10 mm, width 28 mm, thickness 0.3 mm) with paper material as the substrate material 2 is placed in the above insect repellent liquid. In the product obtained by soaking for about 3 hours and sufficiently impregnating with the chemical solution, the insect repellent solution contained is mainly contained in the substrate material 2, but it also penetrates into the ground color layer 3 and becomes transparent. The surface of the paper-like material 1 exhibited the base 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 contained insect repellent liquid is It was released in a sustained manner from the back side of the board 2, and the coloration in terms of its display function was maintained as it was for about 6 months, and it exhibited an effective insect repellent effect. 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 is mostly limited to the back surface of the substrate material 2, and the point of disappearance coincides with the point 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 on the second surface of the substrate material, the color scheme of the substrate material 2 itself can be applied as it is, as in the above-mentioned Example 1, but the function as the display device described above can be sufficiently adjusted. It is desirable that there is a large difference in hue between the changes in coloration to achieve this effect, for example, between the coloring of the ground color layer 3 and the coloring of the substrate material 2.
The base color of the surface is "white and black", "black and yellow", "red and blue"
It is appropriate to use a combination of colors such as:

The color tone configuration of the above combination is realized by the second embodiment shown in FIG. 2 in the present invention. That is, this is a case where a paper-like material A' made of a paper-like material 1' having a base colored layer 2a formed by coating an oil-liquid permeable colorant on the surface of the substrate material 2 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 made by appropriately mixing a colorant such as a pigment or dye with the above-mentioned binder.
By applying a prepared liquid mixed preferably at a mixing ratio of 1:0.1 to 0.1 to 3 (parts by weight), it can be formed to have the necessary coloration and appropriate oil permeability.

Next, Embodiment 3 of the present invention shown in FIG. 3 applies a paper-like material B having a structure in which a sheet-like porous material such as sponge is fixed as a separating material 5 on the back surface of the paper-like material 1. This is an insect repellent material that doubles as an insect repellent indicator. In this paper-like material B, the separating material 5 covers the volatilized gas emitting surface of the substrate material 2, and for example, the separating material 5 is attached to an object to be insect-proofed such as clothing with the display function side of the covering 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.
Pattern layer 3a made of oil impermeable material on the ground color layer 3 part
The paper material 1a is formed into a linear or band shape. In this paper-like material C, the transparent state due to the insect repellent liquid agent contained is obtained only in the ground color layer 3 excluding the pattern layer 3a, so it is based on the ground color of the substrate material 2 and the coloring in the ground color layer 3. It becomes possible to confirm the appearance or disappearance of the formed pattern from the outside depending on the color tone.

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 as follows.
It can also be demonstrated when applying C″.
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, and the paper-like material C'
C″ has a structure in which the pattern layer 2b is formed on the base colored layer 2a of the paper-like material A′.When applying these paper-like materials C′ and C″, It functions so that the pattern formed by the pattern layer 2b completely disappears when the background color layer 3 becomes opaque as the chemical solution disappears. Therefore, the display becomes extremely noticeable.

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

Next, a seventh embodiment of the present invention relating to another pattern display structure is shown in FIGS. 8 and 9. The paper-like material D in Example 7 has a structure in which a pattern layer 4a is formed on the bonding surface of the cover material 4. In addition, 4' in the figure
indicates partially peeled covering material. Even when this paper-like material D is applied, it functions so that the pattern formed by the pattern layer 4a appears or disappears 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 material of the pattern layer 4a of this paper-like material D is not particularly limited, and a wide variety of forming materials can be applied, and it can be easily obtained by a simple forming method. Compared to the paper-like materials C, C', and C'' in which the layers are formed in conjunction with the background color layer 3 or the base color layer 2a of the paper-like material, it has an extremely simple structure and is more complicated. A pattern configuration can be obtained.

Furthermore, the structure of the pattern display on the paper-like material D can be adjusted by using the paper-like materials 1a, 1b, or 1'a described in Examples 4, 5, and 6, respectively, for the paper-like material portion thereof. It is possible to obtain two pattern layers,
The display pattern created by the combination of these pattern layers also makes it possible to exhibit the display function of a variety of pattern shapes that change in a complex manner.

Next, FIGS. 12 and 13 show specific examples of usage of the above-mentioned insect repellent material that also functions as an insect repellent indicator according to the present invention. In this usage example, a paper-like insect repellent material D that also functions as an insect repellent indicator is housed in a container 10 that is formed into a frame shape and has a front opening 11, with its display function side positioned in the direction of the front opening 11. ing.
