Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a double-sided pressure-sensitive adhesive tape made of rubber, and more particularly to a double-sided pressure-sensitive adhesive tape suitable for sticking and peeling hard objects such as wooden products or hard products such as wooden products and glass products.
[0002]
[Prior art]
As is well known, a rubber double-sided pressure-sensitive adhesive tape generally has a pressure-sensitive adhesive layer provided on both front and back surfaces of a rubber base material.
[0003]
[Problems to be solved by the invention]
By the way, with this rubber double-sided adhesive tape, for example, when it is necessary to peel off both parts after adhesively bonding the periphery of hard wooden products, it is extremely difficult to peel off hard wooden products. There was a problem of being hurt.
[0004]
The present invention has been made in order to solve such a conventional problem, and an object of the present invention is to bond hard objects, for example, wooden products, or after adhesively bonding the surroundings of the glass products and the glass products, to obtain the both. It is an object of the present invention to provide a rubber double-sided pressure-sensitive adhesive tape that can be easily peeled off and separated without damaging a base or the like when it becomes necessary to peel the tape.
[0005]
[Means for Solving the Problems]
For this purpose, the rubber double-sided pressure-sensitive adhesive tape according to claim 1 of the present invention comprises a tape-shaped rubber substrate 10 and pressure-sensitive adhesive layers 11 and 12 provided on both front and back surfaces of the rubber substrate 10. And a peeling auxiliary member 13 adhered in the longitudinal direction of the upper surface of one of the pressure-sensitive adhesive layers 11 and 12 or both pressure-sensitive adhesive layers 11 and 12. When the rubber substrate 10 is pulled together with the peeling assisting member 13, the rubber base material 10 is easily extended by the peeling assisting member 13, the tape width is gradually reduced, and the adhesive area is reduced. It is characterized in that it is peeled off.
[0006]
The rubber-made double-sided pressure-sensitive adhesive tape according to claim 2 of the present invention is characterized in that the peeling assisting member 13 is a thread or mesh of synthetic fibers such as nylon.
[0007]
The rubber double-sided pressure-sensitive adhesive tape according to claim 3 of the present invention is characterized in that a knob portion 14 having a non-adhesive surface is formed at an end of the rubber base material 10.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described with reference to the drawings and the operation thereof.
[0009]
FIG. 1 is a partially omitted plan view of an example of a rubber double-sided pressure-sensitive adhesive tape according to the present invention, FIG. 2 is a partially enlarged sectional view taken along line 2-2 of FIG. 1, and FIG. In these drawings, the rubber double-sided pressure-sensitive adhesive tape includes a rubber base material, a pressure-sensitive adhesive layer, a release assisting member, and a release paper.
[0010]
It is preferable that the tape-shaped rubber base material 10 is a material which has excellent weather resistance and does not break even when pulled.
[0011]
Pressure-sensitive adhesive layers 11 and 12 are provided on both front and back surfaces of the rubber base material 10.
[0012]
In the longitudinal direction of the upper surface of one of the pressure-sensitive adhesive layers 11, 12, a peeling assisting member 13 is adhered to the entire longitudinal direction.
[0013]
When the rubber substrate 10 is pulled together with the peeling assisting member 13 when the rubber substrate 10 is pulled together with the hard material, for example, the wooden product and the glass product after the adhesive bonding of the wooden product and the glass product, the peeling assisting member 13 causes the rubber to be peeled off. The base material 10 is a member having a function of easily extending together with the pressure-sensitive adhesive layers 11 and 12, reducing the pressure-sensitive adhesive area of the pressure-sensitive adhesive layer 11 (or the pressure-sensitive adhesive layer 12), and easily peeling off.
[0014]
As shown in FIG. 1, the peeling assisting member 13 may be adhered to a central portion in the longitudinal direction of the upper surface of the pressure-sensitive adhesive layer 11 as a thread-like body of a synthetic fiber such as nylon. As shown in FIG. 4, three pieces may be adhered at equal intervals, and the number is arbitrary.
[0015]
Further, as shown diagrammatically in FIG. 5, the peeling assisting member 13 may be a mesh of synthetic fibers such as nylon, which may be adhered in the longitudinal direction of the upper surface of the pressure-sensitive adhesive layer 11.
[0016]
In any case, when the rubber base material 10 is pulled by the rubber base material 10, the rubber base material 10 easily expands together with the pressure-sensitive adhesive layers 11 and 12, and It is sufficient if the width gradually decreases, and the adhesive area of the pressure-sensitive adhesive layer 11 (or the pressure-sensitive adhesive layer 12) is reduced, so that the pressure-sensitive adhesive layer 11 has a function of easily peeling off. Not something.
[0017]
In this embodiment, the peeling assisting member 13 is adhered on the surface of one adhesive layer 11, but it is needless to say that it may be adhered on the surface of both adhesive layers 11, 12. is there.
[0018]
An end portion of the rubber base material 10 is a knob portion 14 in which a corresponding portion of the pressure-sensitive adhesive layers 11 and 12 has a non-adhesive surface.
[0019]
The knob portion 14 is preferably formed in a slightly wide flat shape or the like, as can be seen at a glance.
[0020]
Release papers 15 and 16 are provided on the upper surfaces of the adhesive layers 11 and 12, respectively.
[0021]
The rubber double-sided pressure-sensitive adhesive tape constructed as described above is used to bond the objects to be bonded 20 and 21 with each other as shown in FIG. As illustrated, the release papers 15 and 16 are peeled off, and one adhesive layer 11 is adhered to one bonded body 20 together with the release assisting member 13, and the other adhesive layer 12 is bonded to the other bonded body 21. And the two joined bodies 20 and 21 are joined.
[0022]
Further, in order to peel and separate the joined bodies 20 and 21, the rubber substrate 10 is peeled by holding the knob portion 14 which is a non-adhesive portion and pulling the rubber substrate 10 outward together with the peeling assisting member 13. It is easily extended by the auxiliary member 13, the tape width is gradually narrowed, the adhesive area is reduced, and the joined body 21 can be easily peeled from the joined body 20 without being damaged.
[0023]
【The invention's effect】
Thus, according to the present invention, since the peeling auxiliary member is adhered to one or both surfaces of the pressure-sensitive adhesive layer, hard objects, for example, after adhesively bonding between wood products or around the glass product, When it is necessary to peel both, it has a knob part which is a non-adhesive part, and if the rubber base material is pulled outward together with the separation auxiliary member, the rubber base material is easily extended by the separation auxiliary member, The tape width is gradually reduced, the adhesive area is reduced, and the tape can be easily peeled off without damaging the base or the like.
