Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pressure-sensitive adhesive tape and a pressure-sensitive adhesive method using the pressure-sensitive adhesive tape, and more particularly to a pressure-sensitive adhesive tape and a pressure-sensitive adhesive method suitable for use in attaching a flooring material to a floor base.

[0002]

2. Description of the Related Art Adhesive tapes are used in many fields such as adhesive tapes for packaging, adhesive tapes for office use, adhesive tapes for medical use, and double-sided adhesive tapes for building materials. Conventional adhesive tapes are coated or partially impregnated with one or both sides of one side or both sides of paper material such as impregnated paper as a base material, resin material such as nonwoven fabric, polyester film or its foam, etc. The adhesive is applied in such a state that the adhesive surface has substantially the same adhesive strength over the entire surface. In the adhesive method using an adhesive tape, it is common that the adhesive surface of the adhesive tape and the object to be adhered are brought into contact with each other as they are and press-bonded, so that the two are adhered to each other.

[0003]

In many cases, it is desired that the pressure-sensitive adhesive tape be firmly adhered to the object to be adhered at the same time that the adhesive tape is brought into contact with the object to be adhered. Instead of sticking, after bringing both into contact, moving either the sticky tape side or the sticky object side or both to determine the relative position to be sticked between them, that is, after positioning, the final May be required to be in a tacky state.

[0004] For example, when a floor material having a double-sided adhesive tape adhered to the back surface is applied to the floor base surface, after removing the release paper, the floor material is temporarily placed on the floor base surface, and the floor material is placed on the floor base surface. While shifting along, it is made to approach the floor material that has been pasted and pasted while aligning it, so that the two can be fitted together, but if you do not pay enough attention to the work, At the moment the floor material is placed on the ground, the double-sided adhesive tape on the back of the floor material is inadvertently and firmly adhered to the floor base surface, making it difficult to move, and fixed so that it is not possible to perform sufficient sun alignment Can occur. In such a case, a gap will be formed in the portion for engaging the spring, which is not preferable.

[0005] In addition, when two sheets with a picture pattern are to be joined together by using an adhesive tape while matching the picture pattern, the edge of one sheet is exposed with almost half of the adhesive surface of the adhesive tape exposed. In the adhesive tape, another sheet is moved while adjusting the position in the length direction of the adhesive tape, and the picture is joined and joined. In the process, a part of the sheet is partially adhered to the adhesive sheet. It is a common experience that the ink is adhered to the substrate and that the subsequent alignment cannot be performed.

SUMMARY OF THE INVENTION It is an object of the present invention to easily solve the above-mentioned inconvenience caused when a double-sided pressure-sensitive adhesive tape or a single-sided pressure-sensitive adhesive tape is used to adhere to an object while being positioned. It is to disclose an adhesive tape and an adhesive method using the adhesive tape.

[0007]

The pressure-sensitive adhesive tape according to the present invention for solving the above-mentioned problems basically has a large number of non-adhesive projections arranged on the pressure-sensitive adhesive surface of the pressure-sensitive adhesive tape so as to exceed the pressure-sensitive adhesive surface. It is characterized by having been done. The adhesive tape may be a double-sided adhesive tape or a single-sided adhesive tape. In the case of a double-sided pressure-sensitive adhesive tape, the non-adhesive protrusion may be formed on only one pressure-sensitive adhesive surface or may be formed on both pressure-sensitive adhesive surfaces.

The pressure-sensitive adhesive tape according to the present invention is prepared by coating (or partially impregnating) a pressure-sensitive adhesive on one or both surfaces of a substrate, as in a conventionally known double-sided pressure-sensitive adhesive tape or single-sided pressure-sensitive adhesive tape. Using a pressure-sensitive adhesive tape as a base, on the adhesive surface, at the construction site or in the process of manufacturing the adhesive tape, it is possible to arrange the protrusions without adhesive force, or on one or both surfaces of the substrate After forming the protrusion having no adhesive force, the pressure-sensitive adhesive layer may be formed to be lower than the height of the protrusion.

Accordingly, as the material for the base of the pressure-sensitive adhesive tape and the material for the pressure-sensitive adhesive in the present invention, those of the conventional pressure-sensitive adhesive tape can be used as they are.
There is no particular limitation on the shape of the protrusion, but a number of narrow convex bodies may be formed on the adhesive surface in a linear or lattice shape, and a large number of columns, weights, spheres, grains, etc. A large number of protrusions may be discontinuously distributed on the adhesive surface.
As will be described later, the pressure-sensitive adhesive tape according to the present invention is pressed from above during use, whereby the protrusions are deformed or move to the substrate side, whereby the pressure-sensitive adhesive surface comes into contact with the surface of the adherend. More sticky. Therefore, as a material forming the projection, a material which is not usually easily deformed but can be deformed into a flat state by being pressed, that is, a material such as rubber, plastic foam, or deformed The material may be a material having a hardness enough to enter the base material side, for example, a metal such as aluminum, iron, and copper, or a synthetic resin such as polyethylene and vinyl chloride resin, and is not particularly limited.

The pressure-sensitive adhesive tape according to the present invention is preferably placed on a flat plate or rolled up with a release paper disposed on the pressure-sensitive adhesive side. When sticking,
After peeling off the release paper, the adhesive surface side and the adhered body are opposed to each other. The non-adhesive projection projects beyond the adhesive surface, and the adhesive on the adhesive surface side and the adherend do not directly contact each other in that state. Therefore, the adhesive surface side and the object to be adhered can relatively easily slide and move, and the operator can easily and surely align the two with the position to be truly adhered.

After the alignment, the pressure-sensitive adhesive surface side and the pressure-sensitive adhesive body are pressed against each other. As a result, the non-adhesive projection is deformed flat or displaced in the direction toward the base material, so that the surface of the pressure-sensitive adhesive can be in contact with the adherend, at which point they are adhered.

In another aspect of the adhesive method using an adhesive tape according to the present invention, the non-adhesive member which can be deformed flat by the pressing or can be shifted to the substrate side is a member separated from the adhesive tape. The non-adhesive member is disposed between the adhesive surface of the adhesive tape from which the release paper has been peeled off and the surface of the object to be adhered at the construction site. Also in this case, the adhesive surface side and the adherend can relatively easily slide and move, and the alignment between them can be easily and reliably performed. After the alignment, by pressing the pressure-sensitive adhesive surface side and the pressure-sensitive adhesive object, as in the case described above, the pressure-sensitive adhesive surface and the pressure-sensitive adhesive material can be in contact with each other, at which point both are adhered. .

A bar-shaped bar member 15 made of the same material as that of the bar member 14 is arranged as a projection having no adhesive force.

FIG. 3 is a side view showing still another embodiment. This sticky tape 3 has a back surface of the rod member 14.
It differs from the one shown in FIG. 1 in that it reaches not the surface position of the adhesive surface 12 but the surface position of the base material 11, and the other configuration is the same. In the drawing, reference numeral 31 denotes a release paper attached to the adhesive surface 12 side. Although not particularly shown, the release paper 31 is also attached to the adhesive tape of the embodiment shown in FIGS. 1 and 2 as necessary.

Next, an adhesive method using the above-mentioned adhesive tape will be described. FIG. 4A is a side view showing a state in which the double-sided adhesive tape 1 shown in FIG. 1 is attached to the back surface of a conventionally known floor material F, in which the bar member 14 of the double-sided adhesive tape 1 is not arranged. The adhesive surface 13 is attached to the back surface of the floor material F and is integrated. In addition, double-sided adhesive tape 1
A release paper 31 is attached to the adhesive surface 12 on the side where the bar member 14 is disposed.

The double-sided adhesive tape 1 is placed on the floor surface G with the lower side facing down. In the state where it is installed, the rod member 14 which is a protrusion is provided.
Is only in contact with the floor base surface G, and a space is formed between the floor base surface G and the adhesive surface 12. Since the surface of the rod member 14 has no adhesive force, the worker can freely move the floor material F on the floor base surface G.

After moving the floor material F to a desired position, the operator presses the floor material F from above to the floor base surface G.
FIG. 4b shows the state, in which the rod member 14 moves toward the base material 11 by being pressed, and in this example, penetrates into the adhesive of the adhesive surface 12, and the surface of the adhesive surface 12 and the floor ground surface G Is in contact with Thereby, the floor material F is stuck and fixed to the floor base surface G. The pasting operation is performed on the next floor material F while performing positioning in the same procedure. Thus, it is possible to easily and reliably perform the positioning of the floor material F at the time of engagement with the spring.

In FIG. 4B, the rod member 14 is shown to enter the adhesive of the adhesive surface 12 by pressing, but the rod member 14 is inserted so as to enter the base material 11 side.
It will be understood that the size of the adhesive or the thickness of the adhesive may be designed. As shown in FIG. 3, the rod member 14 is
In the case of the pressure-sensitive adhesive tape 3 reaching the surface position of No. 1, the stick member 14 naturally enters the inside of the base material 11 at the time of adhesion.

FIG. 5 is a perspective view showing another embodiment of the adhesive method using the adhesive tape according to the present invention. In this example, a grid-like projection having no adhesive force in the form described in FIG. 2 is used. The stick member 15 is made of the adhesive surface 12 of the double-sided adhesive tape 1a.
Instead of being pre-adhered to the side, a grid-like bar member 15 and a floor material F having a conventionally known double-sided adhesive tape 1a adhered to the back surface are separately carried into the construction site. At the construction site, the worker peels off the release paper from the double-sided adhesive tape 1a surface of the floor material F, and then attaches the grid-like bar member 15 to the adhesive surface 12 of the double-sided adhesive tape 1a. The material F is placed on the floor base surface G, and thereafter, it is aligned and pasted in the same manner as described above.

In another embodiment, instead of attaching the grid-like bar member 15 to the adhesive surface 12 of the double-sided adhesive tape 1a, it is placed on the floor base surface G, and the floor material F from which the release paper has been peeled off is placed on the floor base surface G. Alternatively, positioning and pasting may be performed in that state. In this embodiment, the size of the grid-like bar member 15 is the same as the size of the bottom surface of the floor material F, but may be smaller or larger. Nor. FIG.

According to this adhesive method, there is an advantage that the pasting work of the floor material F, which is accurately positioned, can be performed using the conventional double-sided adhesive tape as it is.
FIG. 6 is a perspective view showing another embodiment of the pressure-sensitive adhesive tape and the pressure-sensitive adhesive method using the pressure-sensitive adhesive tape according to the present invention. The pressure-sensitive adhesive tape 4 is a single-sided pressure-sensitive adhesive tape wound in a roll shape. A large number of protrusions 41 having no adhesive force are arranged so as to slightly protrude from the surface of the adhesive surface. A description will be given of a usage mode in which, for example, two wallpapers a and b are connected using the adhesive tape 4 while matching their patterns.

First, the user takes out the adhesive tape 4 by a required length, puts the edge of one of the wallpapers a on the adhesive tape 4 with almost half of the adhesive surface exposed, and presses from above. Adhere both. Next, another piece of wallpaper b is placed on the exposed portion of the adhesive tape 4 such that the edge substantially abuts against the edge of the already adhered wallpaper a. In this state, the adhesive surface of the adhesive tape 4 and the wallpaper b are not in an adhesive state, and the worker can freely move the wallpaper b in the length direction and the width direction of the adhesive tape 4 and easily. Picture matching can be performed. At the time when the picture matching is completed, the wallpaper b is pressed against the adhesive tape 4 and the two pieces are adhered to each other, so that the two wallpapers are securely joined together in a state where the pictures are matched as shown in FIG.

In the above example, the protrusion having no adhesive force moves to the pressure-sensitive adhesive and the substrate by being pressed from above, thereby allowing the surface of the pressure-sensitive adhesive to come into contact with the surface of the adherend. Although a rod member in the form was shown, it is not particularly shown, but when pressed from above like a rubber material, it can easily be deformed into a flat state to the height of the adhesive surface and the adhesive surface can be brought into contact with the surface of the adherend May be used as the projection. Further, it is understood that the protrusions are not limited to those having a continuous shape such as a rod, and may be a plurality of protrusions, such as columns, weights, spheres, and grains, which are discontinuously arranged.
