Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an adhesive composition suitable for catching small creatures, in particular, harmful insects such as cockroaches and flies, and harmful small animals such as rats, and a small creature capturing device using the same. .

[0002]

2. Description of the Related Art Conventionally, as means for capturing small organisms such as harmful insects such as cockroaches and flies and small harmful animals such as rats, for example, a composition having adhesiveness to a support such as paper, a plastic film, a plate, etc. In general, a catching tool coated with is installed in a passage of a small creature or the like, and the sticky catch is performed.

[0003] As a pressure-sensitive adhesive composition used in a small-animal capturing device, for example, even a large-sized and strong leg-powered small animal such as a rat, a leg which is depressed by its own weight is fitted into the pressure-sensitive adhesive layer coated with the pressure-sensitive adhesive composition. It is important that the leg has sufficient adhesiveness to prevent the leg from being pulled out, and elongation that follows the movement of the captured leg to some extent, that is, foot pulling. Also,
When applying the pressure-sensitive adhesive composition to the support, it is necessary to have a certain heating stability, and when using a capturing tool by setting the coating workability and the pressure-sensitive adhesive layer surface vertically, Considering the case where the capturing device is placed vertically when storing or transporting the capturing device, the adhesive composition protrudes from the support,
It is required that the pressure-sensitive adhesive composition has sufficient flow resistance so as not to flow out. Further, from the point of transport and storage of the capturing device, it is preferable that the coated surface having the adhesive property is covered with release paper until immediately before use, and has a releasability enough to easily remove the release paper. It is desired to have a pressure-sensitive adhesive composition. Further, it is necessary to have weather resistance capable of maintaining the trapping performance such as the adhesiveness even if the release layer is peeled off and the adhesive layer surface is exposed by using the capturing layer for a long time as a capturing device.

Until now, as an adhesive composition used for capturing various small organisms, for example, a composition comprising polybutene and polyisobutylene has been reported in JP-A-55-45366. However, this composition has low cohesive strength and lacks flow resistance, and when the proportion of polyisobutylene is increased, the cohesive strength can be increased. Occurred. Furthermore, release properties of release paper cannot be expected at all. Therefore, as a material having improved flow resistance, for example, a mixture of non-crystalline polypropylene with a composition comprising polybutene and polyisobutylene is reported in JP-A-57-183701. However, although this composition has an adhesive strength enough to capture mice and the like, there is a problem that the release property of the release paper is inferior. In addition, when the proportion of amorphous polypropylene or the like in this composition is increased, the releasability of the release paper is improved, but there is a problem that the adhesiveness is remarkably reduced.

[0005] As described above, at present, there is no report of a pressure-sensitive adhesive composition having all the above-mentioned properties required for capturing small organisms.

[0006]

Accordingly, an object of the present invention is to provide a small organism having good stickiness and towability, excellent trapping performance of small creatures, flow resistance and heat stability. An adhesive composition for capturing small organisms, which has excellent properties, good coating workability, excellent release properties of release paper, and has good weather resistance that can withstand long-term use. An object of the present invention is to provide a small creature trap used.

[0007]

Means for Solving the Problems The present inventor has made intensive studies to solve the above-mentioned problems. As a result, by containing polybutene as the component (A), tackiness suitable for capturing small organisms is imparted, and by containing polyisobutylene and / or butyl rubber as the component (B), the adhesive layer is once trapped in the adhesive layer. The proposed small creatures are provided with a towed property so as not to escape, and are selected from the group consisting of crystalline polypropylene, polyethylene, ethylene-polar monomer copolymer, and amorphous poly-α-olefin as the component (C). By containing at least one selected material, excellent flow resistance is imparted, and further, by adding a hydrogenated styrene-based thermoplastic elastomer as the component (D), the adhesiveness and the legging property are significantly reduced. Adhesive with excellent heat stability and weather resistance that can give excellent release properties of release paper without causing It found that it is possible to obtain a Narubutsu, and have completed the present invention.

That is, the adhesive composition for capturing small organisms according to the present invention comprises: (A) 50 to 98% by weight of polybutene;
(B) a number average molecular weight of 10,000 to 2,500,00
0 to 0.5 to 30% by weight of polyisobutylene and / or butyl rubber, and (C) crystalline polypropylene, polyethylene, ethylene-polar monomer copolymer,
0.5 to 30% by weight of at least one selected from the group consisting of amorphous poly-α-olefins and (D) 1 to 45% by weight of a hydrogenated styrene thermoplastic elastomer are essential components. It is contained as.

[0009] The small creature capturing device of the present invention is obtained by applying the adhesive composition for capturing a small creature of the present invention to a part or the whole of a support, and bonding a release paper to the coated surface. is there.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail. In the present invention, the polybutene as the component (A) is obtained by polymerizing isobutylene or by copolymerizing isobutylene and a small amount of another olefin having 4 carbon atoms. It is obtained by polymerizing a part of the butane-butene fraction excluding butadiene in the C4 fraction. By containing polybutene as the component (A), the pressure-sensitive adhesive composition of the present invention can impart tackiness suitable for capturing small organisms.
The polybutene may be hydrogenated.

The number average molecular weight of the polybutene is 200
It is preferably from 4,000 to 4,000. When the number average molecular weight of the polybutene is less than 200, the viscosity of the composition becomes too low to lower the flow resistance, and the adhesive strength tends to be insufficient, and further, an absorbent support such as paper. Bleeding on the support is likely to occur when the coating is applied. On the other hand, if the number average molecular weight of polybutene exceeds 4,000, the viscosity of the composition tends to be too high, and the coating operation tends to be difficult.

In the present invention, it is important that the mixing ratio of the component (A) is 50 to 98% by weight based on the whole composition. If the component (A) is less than 50% by weight, the tackiness will be insufficient. On the other hand, if the component (A) exceeds 98% by weight, the cohesive strength will be reduced, and the legging and flow resistance will be poor. Insufficiently, and the releasability to release paper will fall.

In the present invention, the polyisobutylene or butyl rubber serving as the component (B) must have a number average molecular weight of 10,000 to 2,500,000. Those which are easily dissolved in the polybutene (A) as a main component are preferable. When the number average molecular weight is less than 10,000, the adhesive strength and the legging property are reduced, while the number average molecular weight is less than 2,500.
If it exceeds 000, the viscosity becomes too high, making the coating operation difficult, and further, the adhesive strength is reduced.
As described above, by using polyisobutylene or butyl rubber having an extremely high molecular weight, a pressure-sensitive adhesive composition having the repellency required for capturing small organisms can be obtained. As the component (B), polyisobutylene and butyl rubber may be used alone, or both may be used as a mixture.

In the present invention, it is important that the mixing ratio of the component (B) is 0.5 to 30% by weight based on the whole composition. When the content of the component (B) is less than 0.5% by weight, sufficient towability cannot be exhibited.
If the amount of the component (B) exceeds 30% by weight, the viscosity becomes too high, the fluidity decreases, and the coating workability becomes difficult. The component (C) in the present invention includes crystalline polypropylene, polyethylene, an ethylene-polar monomer copolymer, and an amorphous poly α
At least one selected from the group consisting of olefins, and more specifically, a melt flow rate (AST
Crystalline polypropylene whose MD-1238, 230 ° C.) is 0.3 to 400, melt flow rate (ASTM)
D-1238, 190 ° C) of 0.4 to 400, an ethylene-polar monomer copolymer having a polar monomer content of 30% by weight or less, C3 to
Essentially at least one selected from the group consisting of copolymers of ethylene hydrocarbons having a carbon number of C6 alone or in combination of two or more or amorphous poly-α-olefins which are copolymers of these with ethylene. It is assumed that. By containing such a component (C), the pressure-sensitive adhesive composition of the present invention can exhibit excellent flow resistance.

In the present invention, it is important that the mixing ratio of the component (C) is 0.5 to 30% by weight based on the whole composition. When the amount of the component (C) is less than 0.5% by weight, sufficient flow resistance cannot be exhibited.
When the amount of the component (C) exceeds 30% by weight, the composition itself becomes hard and the tackiness becomes insufficient. The crystalline polypropylene used as the component (C) is mainly composed of an isotactic structure. Specifically, the one obtained by polymerizing propylene and removing by-produced non-crystalline polypropylene by solvent separation is used. Can be. Melt flow rate of crystalline polypropylene (ASTM D-1238,
230 ° C.) is preferably from 0.3 to 400. When the melt flow rate of the crystalline polypropylene is less than 0.3, dissolution in polybutene becomes difficult.
If it exceeds 00, it is difficult to obtain sufficient flow resistance.

The polyethylene used as the component (C) is obtained by polymerizing ethylene by a medium / low pressure method and a high pressure method, and has a melt flow rate (ASTM D
(−1238, 190 ° C.) of 0.4 to 400 is preferably used. Polyethylene having a melt flow rate of less than 0.4 makes it difficult to dissolve in polybutene, while polyethylene having a melt flow rate of more than 400 makes it difficult to obtain sufficient flow resistance.

The ethylene-polar monomer copolymer used as the component (C) has a polar monomer content of 3%.
It is preferably 0% by weight or less. In the case of an ethylene-polar monomer copolymer having a polar monomer content of more than 30% by weight, compatibility with polybutene deteriorates, dissolving becomes difficult, and sufficient flow resistance is hardly obtained. The polar monomer is not particularly limited as long as it is copolymerizable with ethylene, and examples thereof include vinyl acetate, methyl acrylate, ethyl acrylate, acrylic acid, methyl methacrylate, ethyl methacrylate, methacrylic acid, and monoxide. Carbon or the like can be used alone or in combination of two or more. Among the copolymers of ethylene and these polar monomers, in particular, ethylene-vinyl acetate copolymer, ethylene-methyl acrylate copolymer,
Ethylene-ethyl acrylate copolymer, ethylene-ethyl acrylate-acrylic acid copolymer, ethylene-ethyl acrylate-vinyl acetate copolymer are preferred, more preferably ethylene-vinyl acetate copolymer, ethylene-
Ethyl acrylate copolymer is preferred.

The amorphous poly-α-olefin used as the component (C) is mainly a copolymer of ethylene hydrocarbon having a carbon number of C 3 to C 6 alone or in combination of two or more, or a copolymer of ethylene and ethylene. It is a polymer. Specifically, for example, amorphous polypropylene, propylene-ethylene copolymer, propylene-butene copolymer, ethylene-butene copolymer, ethylene-propylene-butene copolymer, or copolymerized with hexene and the like And the like. The amorphous poly α
The olefins are mainly produced by polymerization as having a certain controlled quality. Amorphous polypropylene (APP) by-produced during the production of crystalline polypropylene can be used. At this time, the amorphous polypropylene may contain several percent of crystalline polypropylene or other by-products during the production of crystalline polypropylene. Further, the type of copolymerization may be any of random type, block type and kraft type.

In the present invention, a hydrogenated styrene-based thermoplastic elastomer as the component (D) must be contained as an essential component. By containing a styrene-based thermoplastic elastomer, the compatibility of the pressure-sensitive adhesive composition is good, it is possible to impart cohesive strength with a relatively low viscosity, without significantly reducing good tackiness and towability, Excellent release properties of the release paper can be exhibited, and furthermore, by hydrogenating this elastomer, an adhesive composition having good heat stability and weather resistance can be obtained.

As the hydrogenated styrene thermoplastic elastomer, specifically, for example, a styrene-ethylene-butylene-styrene block copolymer obtained by hydrogenating a styrene-butadiene-styrene block copolymer, And a styrene-ethylene-propylene-styrene block copolymer obtained by hydrogenating a styrene-isoprene-styrene block copolymer.

In the present invention, it is important that the mixing ratio of the component (D) is 1 to 45% by weight based on the whole composition. When the component (D) is less than 1% by weight, good release properties cannot be exhibited when releasing the release paper,
On the other hand, when the component (D) exceeds 45% by weight, the tackiness becomes insufficient. In the present invention, it is preferable that the composition further contains a natural or synthetic tackifier resin in addition to the essential components (A) to (D).
The tackifying resin is mainly a solid pressure-sensitive adhesive substance, which imparts fluidity and tack by blending with a polymer to improve adhesive strength and adhesion to a support. As the synthetic tackifying resin,
There are petroleum-based tackifying resins and hydrogenated petroleum-based tackifying resins, and examples thereof include aliphatic, aromatic, copolymer, alicyclic hydrogenated, and hydrogenated aliphatic. Examples of the natural tackifying resin include a rosin-based tackifying resin and a terpene-based tackifying resin, and examples thereof include a rosin / rosin derivative, a terpene resin, and a terpene phenol resin. The softening point of the tackifier resin is preferably from 70 to 140C. If the softening point is less than 70 ° C., the adhesive strength will be insufficient. On the other hand, if the softening point exceeds 140 ° C., the adhesiveness will be insufficient, which is not preferable.

In the present invention, the mixing ratio of the tackifier resin is preferably 1 to 30% by weight based on the whole composition. If the tackifier resin is less than 1% by weight, sufficient tackiness cannot be imparted, while if the tackifier resin exceeds 30% by weight, the temperature dependency increases,
It is not preferable because the adhesiveness is lowered and the adhesive composition becomes hard, so that it does not exhibit sufficient towability.

The pressure-sensitive adhesive composition for capturing small organisms of the present invention preferably contains an attractant in order to efficiently attract the small organisms to be captured to the capturing device. Examples of the attractant include vegetable oils such as rapeseed oil, soybean oil, and peanut oil; animal oils such as whale oil and cod oil; animal powders such as fish and meat; vegetable powders such as cereals and vegetables; cheeses and butters; Processed foods; sugars such as molasses and sugar; attracting substances such as pheromones and flavors; and the like. The components (A) to (D)
Since the pressure-sensitive adhesive composition of the present invention composed of the components does not have a peculiar odor, the effect of the attractant can be effectively exhibited without the small creature to be captured being repelled by the odor.

In the pressure-sensitive adhesive composition of the present invention, if necessary,
Various known additives, for example, antioxidants, antioxidants,
An ultraviolet absorber or the like can be appropriately added. The small organism capturing device of the present invention is obtained by applying the above-mentioned adhesive composition for capturing small organisms of the present invention to a part or the whole of a support, and laminating a release paper to the coated surface. When the catcher is installed in a passage for small creatures, the release paper is peeled off and used. By adhering release paper to the coated surface of the adhesive composition, it is possible to ensure the convenience of transporting and storing the catcher, and the adhesive composition of the present invention has a releasability of release paper. Therefore, when using the catcher, the release paper can be easily removed without lowering the catching performance.

The support may be, for example, a sheet,
An appropriate shape such as a tubular shape or a vessel shape can be adopted. The material is not particularly limited as long as the adhesive composition can be applied thereto. For example, a material such as paper or plastic can be used.
The capturing device of the present invention is obtained by coating the adhesive composition on a part or the entire surface of such a support.

The release paper is not particularly limited. Specifically, for example, a paper or a paper made of polypropylene or polyethylene terephthalate coated with a release agent such as a silicone resin is used. Good.

[Table 2]

As is clear from Table 1, the pressure-sensitive adhesive compositions of the present invention obtained in Examples 1 to 3 have good tackiness and legging properties. It was excellent in flow resistance and heat stability, and also excellent in release property of release paper. Since the pressure-sensitive adhesive composition of the present invention obtained in Example 4 contains the tackifier resin of the present invention, the pressure-sensitive adhesive composition was more excellent in adhesive strength than Example 1. The pressure-sensitive adhesive composition of the present invention obtained in Example 5 has a higher ratio of the component (D) than that of Example 1, and thus has a low heat resistance and a low heat-flow resistance, although it is slightly inferior in foot-drawing property and cockroach-capturing performance. And the adhesive strength was extremely high. The pressure-sensitive adhesive composition of the present invention obtained in Example 6 comprises (A)
Since the ratio of the components is higher than that of Example 1, the adhesive strength is lower than that of Example 1, but it has sufficient tackiness for capturing cockroaches, and furthermore, the towability, flow resistance, and heat stability are good. Also, the releasability of the release paper was excellent. The pressure-sensitive adhesive composition of the present invention obtained in Example 7, which uses polyethylene as the component (C), has a slightly lower adhesive strength than that of Example 1, but is particularly excellent in heat resistance at 80 ° C. Was something. The pressure-sensitive adhesive composition of the present invention obtained in Example 8 has a higher proportion of the component (B) than that of Example 1, and thus has a lower adhesive strength than that of Example 1, but has sufficient tackiness for capturing cockroaches. In addition, it had good towing properties, flow resistance, and heat stability, and was excellent in release properties of release paper.

On the other hand, as is clear from Table 2, Comparative Example 1
Since the pressure-sensitive adhesive composition obtained in (1) did not contain the component (D), the pressure-sensitive adhesive strength and the legging property were good, but the release property of the release paper was completely lacking. Since the pressure-sensitive adhesive composition obtained in Comparative Example 2 does not contain the component (D) and has a high proportion of the component (C), the tackiness and the dragging property are low, and it is difficult to capture cockroaches. In addition, the release property of the release paper was poor. Since the pressure-sensitive adhesive composition obtained in Comparative Example 3 was composed only of the components (A) and (B), the pressure-sensitive adhesive composition lacked flow resistance and also had poor release properties of release paper. In the pressure-sensitive adhesive compositions obtained in Comparative Examples 4 and 5, since the non-hydrogenated thermoplastic elastomer was used instead of the component (D), the compatibility and fluidity of the pressure-sensitive adhesive composition were poor, and It could not be used as. The pressure-sensitive adhesive composition obtained in Comparative Example 6 was
Since the content of the component (D) exceeds the range of the present invention,
Although the release paper was excellent in releasability, it was difficult to catch cockroaches due to low adhesive strength and low towability.

[0039]
