Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an improvement of an insect repellent tape that has a repellent effect against cockroaches, ticks, and the like.

(Prior art) Conventionally, as an insect repellent tape, for example,
As shown in Japanese Patent No. 124374, a carrier made of an ultra-soft synthetic resin material, an insecticide layer provided on the surface of the carrier, and an adhesive layer provided on the back surface of the carrier is known. . In the conventional insect repellent tape mentioned above, the insecticide is applied directly onto the carrier, so the insecticide evaporates very easily and the medicinal effect cannot be sustained for a long time.Moreover, the carrier is made of ultra-soft synthetic material. Since it is made of a resin material, it has the disadvantage that sufficient shape retention cannot be obtained.

(Purpose of the invention) The present invention was devised to eliminate the above-mentioned drawbacks, and it provides immediate efficacy, maintains excellent medicinal efficacy over a long period of time, and has sufficient shape retention. The aim is to obtain insect repellent tape with

(Structure of the invention) The insect repellent tape of the invention consists of a substrate made of a hard synthetic resin material, a soft synthetic resin layer provided on the surface of the substrate, an ultraviolet curable paint layer provided on the surface, and a coating that covers the surface. It is composed of a transparent film and an adhesive layer for attachment provided on the back surface of the substrate, and an insecticide is mixed into the ultraviolet curable paint layer and the soft synthetic resin layer, respectively.

(Example) FIG. 1 shows an example of an insect repellent tape 1 according to the present invention. This insect repellent tape 1 is the substrate 2
and a soft synthetic resin layer 3 provided on the surface thereof,
An ultraviolet curing paint layer 4 provided on the surface, a transparent film 5 covering the surface, and the substrate 2
It consists of an adhesive layer 6 provided on the lower surface of.

The substrate 2 is made of a hard synthetic resin material such as hard vinyl chloride and has a shape-retaining property, and has a groove 7 having an inverted V-shaped cross section formed along its length on the back surface thereof. In addition, the soft synthetic resin layer 3 is a soft synthetic resin material manufactured by Mitsui Toatsu Chemical Co., Ltd.
It is made by mixing a pyrethroid insecticide such as MTI-500 Trevon (trade name), an organic phosphorus insecticide, a carbamate insecticide, etc., and is arranged on the surface of the substrate 2 by extrusion molding or other means. .

The ultraviolet curing paint layer 4 is made of a synthetic resin material such as urethane acrylic resin, polyester resin, or epoxy acrylic resin, and is an ultraviolet curing paint that is configured to instantly cure when irradiated with ultraviolet rays. (UV paint) mixed with the above insecticide. This ultraviolet curing paint layer 4 is applied to the surface of the soft synthetic resin layer 3 by means such as roller coating, and then ultraviolet rays are irradiated from above with a transparent film 5 superimposed on the surface. As a result, it is cured and fixed to the surface of the soft synthetic resin layer 3. Incidentally, after forming the ultraviolet curing coating layer 4 on the back surface of the transparent film 5, this may be superimposed on the surface of the soft synthetic resin layer 3 and ultraviolet rays may be irradiated from above.

Further, the adhesive layer 6 is formed by applying an adhesive to the back surface of the substrate 2 or pasting a double-sided adhesive tape. Note that it is desirable that a release paper be provided on the back side of the adhesive layer 6, and that the release paper be peeled off during use.

The insect repellent tape 1 configured as described above is used to prevent cockroaches, ticks, etc. from entering and wandering, for example, on the walls of buildings, on floors, around table tops, on openings in furniture, kitchen utensils, etc. It is attached via the adhesive layer 6 to the periphery of the section.
Further, as shown in FIG. 2, when attaching the insect repellent tape 1 across the bottom surface 9 and side surface 10 of the peripheral wall of the table top 8, the insect repellent tape 1 is bent at the groove 7 of the substrate 2.

Then, when the transparent film 5 of the insect repellent tape 1 is peeled off, the insecticide mixed in the ultraviolet curing paint layer 4 and the soft synthetic resin layer 3 has a medicinal effect to repel cockroaches and the like. That is, the insecticide that vaporizes from within the ultraviolet curing paint layer 4 provides an immediate insect repellent effect, and the insecticide that gradually vaporizes from within the soft synthetic resin layer 3 through the ultraviolet curing paint layer 4 provides long-term protection. Medicinal effects can be obtained over a period of time.

In this way, since the insecticide is mixed into the ultraviolet curing paint layer 4 and the soft synthetic resin layer 3 provided on the surface of the substrate 2, the extrusion molding process is similar to when the insecticide is mixed into the hard synthetic resin. In some cases, the insecticide can be prevented from being exposed to high temperatures and thermally decomposed or evaporated, thereby preventing the insecticide from losing its medicinal efficacy, and also prevents the insecticide from rapidly vaporizing as in the case where the insecticide is applied directly onto the substrate 2. This can prevent the drug's efficacy from disappearing early. Further, since the substrate 2 is made of a hard synthetic resin material, this ensures the shape retention of the insect repellent tape 1, and the presence of the substrate 2 allows the ultraviolet curing paint layer 4 to be It is possible to prevent the insecticide in the resin layer 3 from penetrating into the back side of the insect repellent tape 1 and being wasted.

Furthermore, since the transparent film 5 is disposed on the surface of the ultraviolet curing paint layer 4, the surface of the ultraviolet curing paint layer 4 can be formed into a smooth surface depending on the smoothness of the transparent film 5, and The sealing action of the transparent film 5 can prevent the insecticide from evaporating during storage or other periods of non-use.

In addition, in the above embodiment, since the groove 7 is provided in the substrate 2 made of a hard synthetic resin material, the insect repellent tape 1 is bent at right angles in the groove 7, even though it has a shape-retaining structure. It has the advantage of being able to be installed in the The grooves 7 may be provided at two locations on the back surface of the substrate 2 so that the insect repellent tape 1 can be bent into a U-shaped cross section, or the grooves 7 may be omitted.

(Effects of the invention) As explained above, the insect repellent tape according to the invention has a soft synthetic resin layer mixed with an insecticide on the surface of a substrate made of a hard synthetic resin material.
The substrate can ensure the shape retention of the insect repellent tape, and can also prevent the insecticide from penetrating the back side of the insect repellent tape and being wasted. In addition, since an ultraviolet curing paint layer containing an insecticide was provided on the surface of the soft synthetic resin layer,
The insecticide vaporized from this UV-cured paint layer provides an immediate insect repellent effect, and the insecticide that gradually vaporizes from within the soft synthetic resin layer through the UV-cured paint layer provides medicinal efficacy over a long period of time. It can be sustained. Furthermore, the sealing action of the transparent film provided to cover the ultraviolet curable paint layer prevents the insecticide from evaporating during storage or other times of non-use, thereby maintaining its medicinal efficacy over a long period of time.
