JP2001299187A - Glass wool having rat-preventing property - Google Patents

Abstract

PROBLEM TO BE SOLVED: To prevent a biting damage of a rat by allowing an insulating material and a covering material for a duct and a piping to hold a property of repelling the rat to evade the habit of the rat of biting a material. SOLUTION: A repellent of the rat is nearly uniformly attached to the fiber of a glass wool. Small holes are opened in the cover for covering the outer periphery of the glass wool to impart the repellency of the rat to the outer surface of the covering material.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to glass wool having heat insulation, soundproofing, ant-proofing, rat-proofing and the like used for air-conditioning duct work, hot and cold water piping work, roof work, partition work, and the like.

[0002]

2. Description of the Related Art In conventional duct work, plumbing work, roof work, partition work, and the like, glass wool and rock wool, which are excellent in heat insulation and soundproofness and are relatively inexpensive, are often used.

[0003] In the lagging work for the purpose of keeping the heat of ducts and pipes, it is usual practice to cover the outer surface of a lagging material such as glass wool which is excellent in heat insulation with a jacket material such as an aluminum foil material. .

[0004] The heat-insulating layer of which the outer surface of heat-insulating material such as glass wool is finished with aluminum foil material or cotton tape is damaged by rodents such as rats, and is damaged to the deep part of the glass wool forming the heat-insulating layer. It is not uncommon to do so.

[0005] In the case of a relatively large-sized duct, it is possible to achieve objects such as heat insulation, soundproofing, and ratproofing by lining the inside of the duct with a heat insulating material.

Naturally, glass wool and rock wool are not foods such as rats and whites. The same applies to rubber and the like, but in the case of electric wires and cables, knot mustard extract is kneaded into coated rubber to protect it from rodent bite.

[0007] The use of rodenticides as a diet is not preferred, and therefore, animal repellents are applied as tablets or as liquids, applied or sprayed, or repelled by ultrasonic waves and combined with them to form an extermination system. However, there were problems that could not be satisfied over time and cost.

[0008] Although a method of sticking a tape or the like coated with a rat-proofing agent to the whole or partly has been taken,
It cannot be prevented from being devoured, and is completely vulnerable after being breached.

[0009] Basically, the ability to resist the so-called "test biting behavior _{" of} a mouse, that is, not to bite a mouse, and the fact that it is no longer bitten after a bite is a complete thing as a rat-proof means. Hard to say.

[0010]

It is necessary to foster and maintain an environment in which the rat repels the environment at the edge of the rugging material, not based on the utility based on the learning effect of the mouse.

An object of the present invention is to enable a situation in which a lagging material repels a mouse for a long period of time.

[0012]

In order to achieve the above-mentioned object, in the present invention, a mouse wool repellent is applied almost uniformly to glass wool fibers so that the whole glass wool has a substantially uniform repelling performance. The object is to keep the repelling performance unchanged even if it is arbitrarily cut and formed, and to maintain this performance for a long period of time.

That is, if glass wool has a uniform animal repellent performance as a material and is not harmful in handling, it can be handled and constructed in exactly the same manner as conventional materials, and workability and productivity can be improved. It is promised that it will not cause a decline.

[0014] Animal repellents, especially drugs applicable to the above-mentioned products for the purpose of preventing rats, include, for example, liquid preparations containing cycloheximide, β-naphthol liquid preparations and the like.

Since these animal repellents have stable performance as substances, glass wool containing them can semipermanently maintain their performance as rat-proof glass wool.

However, in order to prevent trial biting, it is necessary that the surface of the aluminum coating material or the like has a repellent property. Therefore, it is necessary to apply a repellent to the surface of the coating material. Alternatively, a small hole must be made in the coating material to expose the part of the repellent substance inside the coating material, thereby giving repellency to the surface of the coating material. In the rat wool-proof glass wool and its coating material system, a small hole is made in the coating material to partially expose the repellent substance inside the coating material.

Some animal repellents, which are harmless to the human body and used as fragrances, are substances that have an effective deodorant odor against rats. Such substances are attached to fibers. Glass wool can easily realize a mouse-repelling environment at the edge of the lagging material by employing a jacket material configured to partially expose the repellent substance inside the coating material.

On the other hand, the lagging material for the purpose of heat insulation is:
In the case where the object to be insulated is at a temperature lower than room temperature, it is required that the construction be performed with careful consideration so as to avoid condensation on the surface.
Drilling in a jacket material that plays the role of a vent is fundamentally inappropriate for lagging work on a low-temperature body, but the present invention does not allow the vent to be evaluated as a factor of condensation. And that it is effective in rat-proof performance.

Further, it should be noted that the ventilation holes may have a role of promoting the generation of mold and bacteria, and that they may further induce rat rods, so that the shape of the flat surface or the curved surface may be reduced. The size, arrangement and spacing of the holes are determined according to the requirements.

If the object to be insulated is in a field where the temperature is higher than room temperature, there is no problem of dew condensation due to the air holes. However, if the temperature changes frequently over room temperature, avoid drilling holes in the jacket material and use a rat-proof tape. It is preferable to take measures such as pasting. When the temperature of the object to be thermally insulated changes, the ventilation action in the lagging layer is generally unavoidable, and the drilling of the jacket material means that the ventilation site is set in advance.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described based on embodiments with reference to the drawings. In FIG.
Is covered with a heat insulating material 12, and the outer periphery is further covered with an aluminum foil tape 13. This is exactly the same as the usual heat insulation construction of a pipe material.

In the present invention, the heat insulating material 12 is obtained by attaching an animal repellent to glass wool glass fiber, and the aluminum foil material 13 is a tape in which round holes 14 having a diameter of 1 ^mm are arranged at intervals of 200 ^mm. The heat insulating material 12 is continuously wound in a spiral tape.

In the embodiment shown in FIG. 2, the outer periphery of the duct 21 is covered with a heat insulating material 22, and the outer periphery is further covered with a sheet 23 of an aluminum foil material. This is exactly the same as the usual heat insulation construction for a duct.

In the present invention, the heat insulating material 22 is obtained by attaching an animal repellent to glass wool glass fiber, and the aluminum foil material 23 is a sheet in which round holes 24 having a diameter of 11 ^mm are arranged at intervals of 500 ^mm. , And is usually formed integrally with the heat insulating material 22.

[0025]

Since the present invention is configured as described above, it has the following effects.

A glass wool in which a drug or a fragrance, which is not preferred by the mouse, adheres to the glass wool fiber and is almost uniformly distributed, can prevent rodent biting. That is, it has rat-proof performance.

When glass wool having such animal repellent properties is used as a heat insulating material and is lagged against a pipe or a duct, the outer surface of the heat insulating material is usually covered with a non-breathable material such as an aluminum foil material. However, it is possible to impart animal repellency to the jacket material by making small holes in the jacket material and arranging the small holes appropriately.

That is, by imparting animal repellency to glass wool, it is possible to prevent rods from sticking to the outer covering material such as aluminum foil.

[0029] Therefore, since rat-proofing measures such as a turtle shell wire mesh can be omitted, the amount of construction work can be reduced, and the construction time can be shortened.
