Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pest repellent tape or sheet capable of maintaining a repellent effect on pests for a long period of time.

[0002]

2. Description of the Related Art Conventionally, for the control of insects such as cockroaches, fleas, ticks, etc., aerosol types using oils and highly volatile substances such as mosquito coils are used.
These are concerned about the effects on the environment and the human body.
In addition, it may adhere to parts other than pests when used, and may contaminate floors, furniture, tableware, and the like. Furthermore, in recent years, one of the causes of failures is the incentive of cockroaches and the like due to heat of home electric appliances and the like. In order to prevent such pests, foods mixed with food are used, but carcasses remain nearby, which may cause further trouble. As a product such as an insect repellent sheet, a product in which a nonwoven fabric or the like is impregnated with a drug is commercially available, but its function is insufficient in terms of sustainability.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The pest control agent according to the present invention is not particularly limited as long as it can exert a pest repellent effect. For example, pyrethroid-based, carber-mate-based, organophosphorus-based drugs, dimethyl-m-toluamide, etc. And natural repellents such as herbs. These drugs and repellents may be used alone or in combination of two or more. Further, a solvent, a binder, or the like may be used. Fatty acid esters having a cyclopropane ring as the basic skeleton of the molecule, for example, pyrethrin and cinerine. This drug can be obtained from pyrethrum by a conventional method, and is also commercially available. A person skilled in the art appropriately sets the addition amount according to the purpose.

Examples of the hydrocarbon polymer according to the present invention include styrene-isoprene-styrene block copolymer, styrene-butadiene-styrene block copolymer, hydrogenated products thereof, natural rubber, synthetic isoprene rubber, styrene-butadiene rubber, Examples include polyisobutylene, butyl rubber or mixtures thereof.

[0010] The hydrocarbon polymer composition according to the present invention may further contain a fatty acid ester. Examples of fatty acid esters include isopropyl adipate, butyl stearate, isopropyl myristate, dioctyl sebacate, and hexyl laurate. Examples of the orthophosphate include trimethyl phosphate, triethyl phosphate, tributyl phosphate, tricridyl phosphate, triphenyl phosphate, tri-2-ethylhexyl phosphate, and the like. The amount added is based on the weight of the hydrocarbon polymer.

If necessary, fillers such as calcium carbonate, silicon oxide and titanium oxide, and antioxidants such as dibutylhydroxytoluene may be added in necessary amounts.

The composition layer according to the present invention is present on one side of a tape or sheet support. Here, the support is
The material and thickness are not particularly limited as long as they are impermeable to the drug. For example, conventional polyethylene terephthalate, polyethylene naphthalate, polyphenylene sulfate and the like can be used. The thickness is preferably 6 to 150 μm from the viewpoint of easy handling.
m, more preferably 12 to 100 μm.

The pressure-sensitive adhesive layer according to the present invention is present on the other surface of the support. The pressure-sensitive adhesive is not particularly limited, but preferably has high adhesiveness to the adherend and does not affect the adherend such as discoloration. For example, in addition to rubber-based pressure-sensitive adhesives obtained by adding various tackifying resins to elastomers such as natural rubber and synthetic isoprene rubber, acrylic pressure-sensitive adhesives composed of acrylate ester copolymers, silicone-based silicone pressure-sensitive adhesives, and the like. No. In the case where re-attachment is required after attachment, adhesive microspheres which can be peeled and attached, for example, described in JP-A-50-2736 can also be used.

The pressure-sensitive adhesive layer further contains various flame retardants, such as antimony oxide, aluminum hydroxide, red phosphorus, and bromine, in order to impart flame retardancy when used for home appliances and electric wires. Fillers such as titanium oxide and calcium carbonate, 3,5-di-t-butyl-
An antioxidant such as 4-hydroxytoluene may be added as needed.

A protective film may be provided on the drug layer to prevent the drug layer from being contaminated with sebum or the like during application and to work without directly touching the drug layer. As protective films, polyethylene, polypropylene, polyethylene terephthalate, nylon,
A relatively smooth plastic film such as polyethylene naphthalate or polyvinyl alcohol is preferable.
As for the pressure-sensitive adhesive layer, release paper such as glassine paper, polylaminate paper, or polyethylene terephthalate film having one surface treated with silicone may be bonded to protect the pressure-sensitive adhesive surface until immediately before use.
