Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproof tape winding body in which a waterproof tape used as a sealing material for joints of a building or the like is wound in a roll shape, and particularly to an outer wall panel of a building to which an outer wall panel is attached. The present invention relates to a waterproof tape winding body in which an adhesive waterproof tape suitable for use as a sealing material for a joint portion which is a gap with an outer wall panel is wound in a roll shape.

[0002]

2. Description of the Related Art A conventional waterproof tape is made of a flexible waterproof material such as rubber in the form of a tape, and the waterproof tape is used by being watertightly attached to a joint portion of a building or the like. In particular, the waterproof tape used for joints, which is the gap between outer wall panels, has better water-tightness if it is attached to the outer wall panels on both sides, so tape-shaped adhesive material should be used. To be Among them, Vol. 4-
As described in No. 21596, an adhesive waterproof tape mainly composed of butyl rubber having good adhesiveness and durability is often used. Since this adhesive waterproof tape mainly composed of butyl rubber has adhesiveness, it is usually stored in a corrugated cardboard or the like after being sandwiched between release papers and rolled into a roll.
Has been transported. Therefore, after peeling off the release paper, an adhesive waterproof tape is attached to a joint portion of a building or the like where water easily leaks.

[0003]

However, the joint portion of the outer wall panel using this adhesive waterproof tape exists not only in a low place but also in a high place. In this high place, the conventional adhesive tape winding body is not formed. It was difficult and inconvenient to use. In other words, when you climb up to a ladder and rewind this waterproof tape roll,
Since this adhesive waterproof tape is sandwiched and wrapped around the release paper, it is completely rewound with the release paper attached at once, and hangs down for a long time. Therefore, it is inconvenient to peel off the release paper attached from the sticky waterproof tape that has hung down for a long time, and to attach it to a portion such as a joint portion where rainwater easily leaks.

Further, since the adhesive waterproof tape is mainly composed of a soft adhesive butyl rubber, the conventional waterproof tape winding body is apt to seep out the adhesive waterproof tape from the side surface due to external pressure or high temperature. It is inconvenient because it adheres to various places, and when they are stacked in a box and packed, they adhere to each other.
There is a problem that it takes a lot of effort to take out each one individually. Therefore, an object of the present invention is to provide a waterproof tape winding body which is easy to use. Another object of the present invention is to provide a waterproof tape wound body in which the waterproof tape does not seep out from the side surface of the wound body.

[0005]

The present invention has been made in order to achieve the above object, and is mainly composed of a polyolefin tape having one surface treated by corona discharge and an adhesive butyl rubber polymerized on the polyolefin tape. The adhesive waterproof tape described above is wound in a roll shape.

In the present invention, the polyolefin tape is a tape-shaped product of a polymer of olefinic hydrocarbon such as polyethylene and polypropylene. In general,
This polyolefin tape is a material having good releasability, but when the surface of the polyolefin tape is subjected to corona discharge treatment, the surface of the polyolefin tape is oxidized and the releasability deteriorates.

The waterproof tape mainly composed of adhesive butyl rubber used in the present invention is a flexible butyl rubber which has a low degree of polymerization and is always adhesive in the form of a tape. Further, a tackifying resin such as an ester rubber may be added to the tacky butyl rubber in order to increase the tackiness, or other additives may be added to form a tape. Since this adhesive butyl rubber is generally flexible, a waterproof tape wound body obtained by polymerizing this adhesive butyl rubber tape and a polyolefin tape into a roll is adhered from the side due to external pressure or high temperature. Butyl rubber may ooze out. Therefore, in order to prevent this exudation, it is necessary to use 2 from both sides of the polyolefin tape.
It is advisable to superimpose the adhesive waterproof tape on the central portion separated by at least mm.

[0008]

Since one side of the polyolefin tape used for the waterproof tape winding body of the present invention is subjected to electric discharge treatment, the surface subjected to electric discharge treatment of this polyolefin tape is inferior in releasability to the opposite side. Therefore, when this waterproof tape winding body is rewound, the adhesive waterproof tape is rewound in a state of being attached to the discharge-treated surface of the polyolefin tape. However, since the surface of the polyolefin tape which has not been subjected to the electric discharge is adhered to the adhesive waterproof tape even if it has good releasability, it is not completely rewound all at once as in the conventional case, but stopped at the rewound position. Therefore, the waterproof tape winding body of the present invention can be rewound and used by a necessary amount.

As described above, the adhesive tape may be rewound by the required amount, and the adhesive waterproof tape attached to the discharge-treated surface of the polyolefin tape may be attached to the joint portion and cut, and then the polyolefin tape may be peeled off for use. The adhesive waterproof tape may be peeled off and cut off, and then the adhesive tape may be attached to the joint portion for use. Even if the discharge-treated surface of this polyolefin tape is oxidized and the releasability is inferior, it can be easily released from the polyolefin tape because it has much better releasability than other materials such as paper. The adhesive waterproof tape can be peeled off.

In the present invention, when a polyolefin tape having one surface subjected to corona discharge treatment and an adhesive waterproof tape polymerized in the central portion separated by 2 mm or more from both sides of the polyolefin tape are wound in a roll shape, Even if it is deformed in the side direction due to the pressure, high temperature, etc., the side edges of the polyolefin tape of 2 mm or more exist on both sides, so that it does not exude from the side surface. Therefore, the waterproof tape winding body does not adhere to other objects, and even when the waterproof tape winding body is stored in a cardboard box or the like for storage or transportation, the waterproof tape winding bodies are not in contact with each other. Does not adhere.

EXAMPLES Next, examples of the present invention will be described. 1 to 3 show one embodiment of the present invention. FIG. 1 is a perspective view showing a state in which a part of a waterproof tape winding body is unwound, and FIG. 2 is cut along a line II-II in FIG. FIG. 3 is an explanatory view showing a usage state of the waterproof tape winding body.

1 to 3, reference numeral 1 is a waterproof tape winding body. Reference numeral 2 is a polyolefin tape. One surface of the polyolefin tape 2 is a surface 21 that has been subjected to corona discharge treatment, and the opposite surface is a surface 22 that has not been subjected to corona discharge treatment. 3 is an adhesive waterproof tape mainly composed of adhesive butyl rubber, and this adhesive waterproof tape 3 is polymerized on the central portion 5 mm apart from both side edges of the polyolefin tape 2. The adhesive butyl rubber 3 and the polyolefin tape 2 are wound into a roll to form a waterproof tape wound body 1. 4 is an outer wall panel attached to the building. A joint portion 5 is a gap between the outer wall panel 4 and the outer wall panel 4. A decorative plate 6 hides the joint portion 5.

Next, a method of using the waterproof tape winding body 1 will be described. The waterproof tape roll 1 is stored and transported in a box such as a cardboard box. Then, during storage or transportation, the soft adhesive waterproof tape 3 may be deformed due to external pressure or high temperature, and may spread laterally. However, the polyolefin tape 2 is spread from the adhesive waterproof tape 3 to both sides. Since it extends 5 mm, it does not bleed from the side surface of the waterproof tape winding body 1. Therefore, when used, the waterproof tape winding body 1 is removed from a box such as a cardboard box.
Can be taken out easily. Further, even if the waterproof tape winding body 1 is placed on a box or the like, it does not adhere to the box or the like.

Next, a state in which the waterproof tape winding body 1 is attached to the joint portion 5 of the outer wall panel 4 will be described.
Hold the polyolefin tape 2 of the waterproof tape roll 1 and rewind it by the required amount. Then, the adhesive waterproof tape 3 adheres to the corona-discharge-treated surface 21 of the polyolefin tape 2 having relatively poor releasability and is rewound. Next, the end of the adhesive waterproof tape 3 is attached to the joint portion 5 of the outer wall panel 4 while being attached to the polyolefin tape 2, and is attached along the joint portion 5 while being unwound. In this way, the adhesive waterproof tape 3 can be applied while being rewound as much as necessary, so that the adhesive waterproof tape 3 can be applied easily, and therefore can be applied safely even in high places.

When the attachment of the adhesive waterproof tape 3 to the joint portion 5 is completed, the polyolefin tape 2 and the adhesive waterproof tape 3 are cut, and then the polyolefin tape 2 is cut.
Peel off. Next, the adhesive waterproof tape 3 attached to the joint portion 5 is pressed from above, and the adhesive waterproof tape 3 is sufficiently attached to the joint portion 5 to make this portion watertight. When the decorative plate 6 is attached on this, the construction of the joint portion is completed.

The embodiment of the present invention has been described in detail above with reference to the drawings. However, the specific structure is not limited to this embodiment, and even if there is a design change or the like without departing from the scope of the present invention. Included in this invention. For example, in this embodiment, the adhesive waterproof tape 3 is adhered to the joint portion in the state of being adhered to the polyolefin tape 2, but the adhesive waterproof tape 3 and the polyolefin tape 2 are wound from the waterproof tape roll 1 in a required amount. Put back and cut, peel off the polyolefin tape 2, and use only the adhesive waterproof tape 3

EFFECTS OF THE INVENTION The conventional waterproof tape winding body is difficult to use because it rewinds all at once and becomes long, but the waterproof tape winding body of the present invention can be rewound by a necessary amount. Very easy to use. In addition, since the polyolefin tape whose mold surface has been subjected to corona discharge treatment and the adhesive waterproof tape polymerized on this polyolefin tape are wound in a roll shape, when rewound, the corona having relatively poor releasability is inferior. Adhesive waterproof tape adheres to the discharged surface and rewinds neatly.

In the present invention, when a polyolefin tape having one surface subjected to corona discharge treatment and an adhesive waterproof tape polymerized in a central portion separated by 2 mm or more from both sides of the polyolefin tape are wound in a roll shape, The adhesive waterproof tape does not ooze out, and therefore the waterproof tape winding body does not adhere to other objects, and even if the waterproof tape roll is stored or transported by stacking it on a cardboard box or the like, Easy to use without adhesion.
