Description

[Detailed description of the invention] (Field of industrial application) This invention is mainly used to prevent damage by winding and coating the surfaces of electric wires, signal cables, communication cables, rubber tubes, and hoses at required locations. This tape is widely used in the industrial field of pest prevention.

(Prior art) It is well known that the extent and scope of damage caused by rats has been increasing in recent years. For example, the main types of damage caused by rats in electrical equipment are damage to electric wires and cables, Damage due to rod contact with the exposed part of the filling.
Damage caused by deterioration of equipment materials due to excrement, damage caused by contact with precision parts and data storage objects (damage caused by contamination), attached parasites, etc.
There is health and hygiene damage due to odors, etc.

Various methods have been developed and implemented to prevent the above-mentioned types of pests.For example, as a measure against the pests of electric wires and cables, it has been proposed to use a rodent repellent mixed into the entire covering material. However, it is uneconomical and unprofitable to make the entire covering material of electric wires and cables rodent-proof, so it is uneconomical and unprofitable.・For reasons such as the need to focus only on cables and other areas, recently we have begun to use anti-rat tapes made by mixing rat repellents, or paints with rat repellents on the surface. Applied pest control tape is used.

(Problem to be solved by the invention) However, in the case of the rodent prevention tape configured as described above, part of the repellent tends to stick to hands when used, which is undesirable from a hygiene standpoint, and Tapes mixed with repellents also have the disadvantage that part of the repellent dissipates and disappears over time, reducing the anti-scalding effect. There is a problem that physical stability and chemical stability tend to decrease, and these problems have not been sufficiently solved even in the case of a tape using a type in which a repellent is encapsulated in microcapsules. Furthermore, the above-mentioned anti-damage tape has the problem that it cannot withstand long-term use because it lacks heat resistance and strength.

The present invention was developed and completed in order to address the above-mentioned problems, and is capable of retaining its rodent repellent effect over a long period of time, as well as being chemically and physically stable with excellent heat resistance and strength. The purpose of the present invention is to provide a tape for preventing rodents with excellent properties.

(Means for Solving the Problems) In order to achieve the above object, in the present invention, a metal foil such as aluminum foil is layered on one side of a rat repellent layer formed by mixing a rat repellent into an adhesive. At the same time, we have developed and adopted a pest-prevention tape that is constructed by layering a tape material made of an organic material such as paper or plastic film on the other side.

(Function) The rodent repellent tape according to the present invention has the function of preventing diffusion and elution of the rodent repellent due to the ventilation and water blocking properties of the metal foil layered on one side of the rodent repellent layer, and the rodent repellent layer In addition to being able to prevent physical changes such as peeling and damage, the metal foil's heat-resistant and flame-retardant properties can also prevent chemical deterioration of the rodent repellent caused by heating. In addition, the tape fabric layered on the other side of the rodent repellent layer can also exert the effect of preventing the diffusion, elution, and chemical deterioration of the rodent repellent from that side, and the tape fabric has shape retention and elasticity. Depending on the strength, reinforcing properties can be imparted to the tape.

(Example) Hereinafter, an example of the present invention will be described based on the accompanying drawings.

In FIG. 2, reference numeral 1 denotes a thin rodent repellent layer, for example, granular or liquid cycloheximide rodent repellent 2 may be used as is, or these layers may be coated with particle size 10.
A rodent repellent 2 encapsulated in minute microcapsules of ~60μ is mixed and kneaded into a synthetic resin adhesive, and its surface is covered with a metal foil 3 made of aluminum foil and a silicone resin. Mold release agent layer 4
are sequentially layered, and a tape base 5 made of an organic material such as paper or plastic film and an adhesive layer 6 are formed on the back side, and this layered composition 7 is cut into pieces with a width of 2 to 20 cm. A long tape body with a thickness of about 0.2 to 0.5 mm was formed and wound around a winding core R to form a roll-shaped pest prevention tape T as shown in Fig. 1. It is something.

The rodent prevention tape of this embodiment is used, for example, by wrapping the metal foil 3 side on the front side and using the adhesive layer 6 at a place where there is a risk of rodent bite on a covered electric wire. Ventilation provided by the metal foil 3;
Due to water barrier properties, heat resistance, flame retardant properties, and other protective effects,
Dispersion, elution, and chemical alteration of the rat repellent 2 and peeling and damage of the rat repellent layer 1 are reliably prevented, and the rat repellent effect can be maintained for a long period of time. Further, the tape base 5 provided on the back side can prevent the rodent repellent from dispersing, dissolving, and changing in quality, and its excellent shape retention can strengthen the tape as a whole. In addition, in the case of this embodiment, the adhesive layer 6 prevents the damage prevention tape T wound into a roll from being deformed, and also prevents the covered electric wire from collapsing.
This has the advantage that it can be easily and easily wrapped around cables and other sensitive areas.

Furthermore, the release agent layer 4 provided on the outermost layer allows the roll tape T wound around the winding core R to be easily peeled off and smoothly pulled out.

Incidentally, in the case of an embodiment in which the adhesive layer 6 is not formed, the release agent layer 4 is naturally unnecessary, and in such a case, an adhesive is separately applied to the back side of the tape material 5 to meet the requirements. It can be glued to the insulated parts.

Although cycloheximide (trade name: naramycin) is exemplified as the rat repellent 2 in each of the above examples, it is natural that other rat repellents can be used, and if a rat repellent containing microcapsules is used, This is useful for improving the durability of the chemical effect of the repellent and improving the safety in handling.

(Effects of the invention) As detailed above, according to the invention, the rodent repellent layer can be isolated from outside air etc. by the metal foil such as aluminum foil layered on at least one side (surface) of the rodent repellent layer. Therefore, the dispersion and elution of the repellent can be prevented,
It can maintain its effectiveness over a long period of time, prevent changes in chemical properties due to sunlight, etc., and can impart heat resistance and flame retardancy to the tape.

Furthermore, the tape material made of an organic material such as paper or plastic film layered on the back side of the rodent repellent layer can prevent the repellent from dispersing, eluting, or changing in quality, and its shape retention properties make the tape The entire structure can be strengthened, and since the rat repellent layer is composed of adhesive mixed with rat repellent, there is no need to use a separate adhesive when layering metal foil and tape. It also has the following.
