JP4040130B2 - Butyl tape for waterproofing - Google Patents

Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a waterproof butyl tape that is used at a joint site where there is a lot of unevenness and the rolling force cannot be expected, for example, a joint site between a concrete material and an aluminum metal fitting in a building.
[0002]
[Prior art]
Conventionally, this type of waterproof butyl tape is continuously formed with a constant thickness and a constant width by an extruder or a calendar. Then, the molded waterproof butyl tape is taken up together with the separator and stored and transported in this state. The thickness, width, and penetration of the waterproof butyl tape are determined in consideration of the adherend, the rolling pressure on the adherend, or the appearance and waterproofness. The separator paper used as the separator uses paper with different recurrence properties on the front and back surfaces, so that when the waterproof butyl tape is stretched from the wound state, a part of the waterproof butyl tape is attached to the other side of the separator. This prevents the butyl material from dripping.
[0003]
[Problems to be solved by the invention]
The waterproof butyl tape is usually molded at a temperature of 60 ° C. to 100 ° C., but is wound with the separator in a short time after the molding. Therefore, after-winding is liable to cause preheating deformation, and this preheating deformation may cause distortion in the wound state or unevenness on the waterproof butyl tape surface. Such distortion in the wound state and the unevenness of the waterproof butyl tape surface cause air to remain in a part of the tape surface at the time of application. And it will be constructed in the state where the tape surface is left uneven by the partial remaining portion of the air. Therefore, the unevenness caused by the remaining air is easy to form a groove for generating a flow of water, and has also been a cause of damage to the waterproof function. Moreover, since it did not contact | connect in the prescribed | regulated area, there also existed a problem that the adhesive force on design could not be obtained.
On the other hand, depending on the construction state, sufficient rolling pressure may not be obtained. In such a case, it has been necessary to increase the thickness of the waterproof butyl tape or increase the penetration to make it soft. However, in such a case, a large amount of butyl member is required, so that not only a high material cost is required, but also the deformation is easily caused, so that the winding state is further distorted or the waterproof butyl tape surface is uneven. There was a problem that it was likely to occur.
[0004]
Accordingly, an object of the present invention is to provide a waterproof butyl tape that does not impair the waterproof function even if distortion in the wound state or unevenness of the waterproof butyl tape surface occurs.
Another object of the present invention is to provide a waterproof butyl tape that can be adhered to an adherend with a small amount of rolling pressure and can be constructed so as to sufficiently perform a waterproof function by forming a plurality of waterstops. .
Another object of the present invention is to provide a waterproof butyl tape that can achieve the above-mentioned object while reducing the material cost.
It is another object of the present invention to provide a butyl tape having a fixed shape by preventing the occurrence of shape deformation due to heat storage secondary aggregation of the butyl tape after winding in the production process.
[0005]
[Means for Solving the Problems]
The waterproof butyl tape according to claim 1 is formed by connecting continuous members having a circular cross section formed from a butyl material molded at a temperature of 60 ° C to 100 ° C. It is characterized by forming continuous grooves and having adhesion on both sides.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
The present invention can ensure continuous adhesion at the ridges by connecting continuous members having a circular cross section . Therefore, waterproofness can be ensured even if there is some distortion in the wound state and unevenness of the waterproof butyl tape surface. In addition, as compared with a flat structure on the entire surface, it is possible to ensure the adhesion at the ridges even with a small rolling force. In addition, the butyl material can be reduced, the material cost can be reduced, and the product weight can also be reduced. Therefore, the number of product packaging can be increased and the packaging cost can be reduced. Furthermore, since a recessed groove is formed by a plurality of protruding portions, heat is radiated by these recessed portions after winding of the production process, so that it is possible to prevent the occurrence of shape deformation due to heat storage secondary aggregation of the butyl tape.
Moreover, this invention can reduce a rolling force and can reduce material cost by providing multiple convex strips on both surfaces, respectively.

In addition, it is possible to reduce the occurrence of deformation and distortion in the wound state by providing the ridges on both sides.
In addition, the waterproof butyl tape of this invention can form a convex part substantially by connecting the continuous member with a circular cross section .

【Example】
Hereinafter , reference examples will be described based on the drawings.
FIG. 1 is a perspective view of a waterproof butyl tape in the reference example .
As shown in the figure, the waterproof butyl tape 10 has the ridges 12A, 12B, 12C, 12D on one surface of the base 11, and the ridges 13A, 13B, 13C, 13D on the other surface, respectively. It is provided continuously in the length direction. These ridges 12 and 13 have a rectangular cross-sectional shape. At this time, the ridge portion 12A provided on one surface of the base portion 11 and the ridge portion 13A provided on the other surface are respectively provided at the same corresponding positions. Similarly, the ridges 12B and the ridges 13B, the ridges 12C and the ridges 13C, and the ridges 12D and the ridges 13D are provided at the same corresponding positions.

At this time, the waterproof butyl tape 10 and the building 100, and the waterproof butyl tape 10 and the aluminum metal fitting 200 are particularly attached to the ridges 12 and 13 before the rolling force is applied. Therefore, when a rolling pressure is applied, this rolling pressure is mainly applied to these ridges 12, 13, so that at least the ridges 12, 13 can be reliably adhered. In addition, since these ridges 12 and 13 are continuous in the length direction, the internal air is pushed out from the groove formed between the ridges 12 and 13 when a rolling force is applied. Therefore, it is less likely to remain on the inner surface of the waterproof butyl tape 10. In addition, since the ridges 10 are continuous in the length direction, the waterproof function is rarely impaired even if all the ridges 12 and 13 are not completely adhered.
According to the present reference example , by providing the plurality of ridges 12 and 13 that are continuous in the length direction, it is possible to ensure continuous adhesion at the ridges 12 and 13. In addition, the adhesiveness at the ridges 12 and 13 can be reliably ensured even with a small rolling force as compared with a flat structure on the entire surface. Furthermore, the butyl material can be reduced, and the material cost can be reduced.
In the above reference example, the ridges 12 and 13 have been described as having a rectangular cross-sectional shape, but a trapezoidal shape, a semicircular shape, or a triangular cross-sectional shape with the base portion 11 side widened. It may be.

In addition, as compared with a flat structure on the entire surface, the adhesion at the ridges 22 can be reliably ensured even with a small rolling force. Furthermore, the butyl material can be reduced, and the material cost can be reduced. In addition, by providing the ridges 22 only on one side, the adhesion to the separator can be made different on both sides, so that it is not necessary to use expensive differential reclamation paper.
