The double-sided self-adhesive sheet S is produced by partially disposing self-adhesive-coated parts 12 coated with a self-adhesive having such a tack force as the self-adhesive is not transferred to an adherend on the peeling of the self-adhesive sheet and self-adhesive- noncoated parts 14 not coated with the self-adhesive on both the surfaces of a support 10 capable of bearing the repeated adhesion and peeling of the self-adhesive sheet. The self-adhesive-noncoated parts 14 are further disposed at constant positions 16 on the periphery of the support.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double-sided pressure-sensitive adhesive sheet for laying floor carpet and a method for laying floor carpet using the same.

[0002]

2. Description of the Related Art A floor carpet is laid on a floor panel in an office or the like in which wiring for OA equipment is laid under the floor panel. Was applied using a roller or the like, and a floor carpet (hereinafter referred to as a carpet) was laid on it.

[0003]

In such a carpet laying method, it is necessary to wait for the adhesive applied onto the panel to dry, the applied part cannot walk, and the adhesive is applied. The work was troublesome because it was difficult to locate the desired position.
In addition, re-coating cannot be done with an adhesive. Furthermore, when changing the layout of wiring, the carpet is first peeled off, and then the panel is removed, but the surface of the panel from which the carpet is peeled off has an adhesive, which makes it difficult to handle when removing. To do.

For this reason, there is a case where a self-adhesive type carpet in which an adhesive agent is previously applied to the back surface of the carpet is used, which does not require the application of the adhesive agent to the panel surface. As a result, it is difficult to handle the carpet, and when the carpet becomes dirty, it cannot be washed and the like, so that the carpet must be replaced with a new one.

On the other hand, there is also a method in which a double-sided adhesive tape is attached to the surface of the panel, and a carpet is laid on it to prevent rubbing. However, even in this method, the double-sided adhesive tape remains on the panel and the carpet after being peeled off, which makes it difficult to handle them. Further, it is possible to peel off the double-sided adhesive tape in order to facilitate the handling of the panel and the carpet when the layout of the wiring is changed, but the work is extremely difficult. Furthermore, when re-bonding, the peeled tape had to be discarded and a new double-sided adhesive tape had to be used, which resulted in dust and was not economical.

[0006] The present invention solves such a problem, and provides a double-sided PSA sheet which is convenient for sticking a carpet and handling a panel and which can be repeatedly stuck.

[0007]

Under the above-mentioned problems, the present invention provides a double-sided pressure-sensitive adhesive sheet for floor carpet laying, wherein the back surface is adhered to the floor panel and the front surface is adhered to the floor carpet. However, both sides of the support that can withstand repeated sticking are coated with a pressure sensitive adhesive that has an adhesive strength that does not transfer the pressure sensitive adhesive to the other side when peeled, and a pressure sensitive adhesive that does not apply pressure sensitive adhesive. A double-sided pressure-sensitive adhesive sheet for laminating floor carpets, wherein the pressure-sensitive adhesive non-coating portion is also provided partially at each of the coating portions and the pressure-sensitive adhesive non-coating portion is also provided at a predetermined position on the periphery of the support.

[0008] In the above-mentioned means, both sides for floor carpet laying, wherein the pressure-sensitive adhesive application portion and the pressure-sensitive adhesive non-application portion excluding the pressure-sensitive adhesive non-application portion at the peripheral edge of the support are provided at positions corresponding to the front and back sides, respectively. Provided is a pressure-sensitive adhesive sheet, and a double-sided pressure-sensitive adhesive sheet for floor carpet laying, wherein the adhesive strength on the back surface side is stronger than that on the front surface side.

Further, the present invention is characterized in that the above-mentioned double-sided pressure-sensitive adhesive sheet is arranged so as to straddle each floor carpet at a position where the floor carpets are butted against each other. A method of applying carpet is provided.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a front view and a back view of a double-sided pressure-sensitive adhesive sheet for floor carpet laying (hereinafter referred to as a sheet) according to the present invention. The sheet S according to the present invention is
An adhesive-coated portion 12 coated with an adhesive and an adhesive-uncoated portion 14 not coated are partially formed on both surfaces of the support 10 having an appropriate size of about 100 mm square, and the peripheral portion is fixed at a certain position. Also has the adhesive non-applied portion 16.

Here, the support 10 is a carrier of an adhesive agent, and a resin film such as polyethylene is adopted for the adhesive agent.
Thickness that can withstand peeling several times (0.2m
m) is selected. As the adhesive, one having a weak adhesive strength such that the adhesive does not transfer to the other party when peeled off is selected. This is for keeping the peeled partner's one clean and enabling cleaning and the like. It should be noted that such an adhesive cannot strongly adhere the panel and carpet strongly, but these are sufficient as long as they are stopped so that they do not laterally shift each other.

On both sides of the support 10, a pressure-sensitive adhesive application portion 12 and a pressure-sensitive adhesive non-application portion 14 are partially formed. In this way, the adhesive applying section 12 and the adhesive non-applying section 1
One of the reasons for partially forming 4 and 4 is that this has a great effect of preventing lateral displacement of the carpet adhered thereto. In this case, it is preferable that each of them is formed at a position corresponding to the front and back. That is, if the specific portion of the front surface is the adhesive-applied portion 12, the corresponding portion of the back surface is formed to be the adhesive-unapplied portion 14. By doing so, the sheets S can be stacked without using release paper. In addition, in order to completely prevent mutual adhesion at this time, a non-adhesive treatment of applying silicon or the like to the surface of the adhesive non-application portion 14 may be performed.

In addition to the above, the front and back sides are fixed at certain points on the periphery.
The adhesive non-applied portion 16 is formed. This is to prevent the adhesive from sticking to the hands or the like by holding this portion when the sheet S is peeled off or carried.

In order to lay a carpet on a panel using the above-mentioned sheet S, first, the sheet S is laid on the panel and adhered to the panel by the adhesive application section 12 on the back surface. Next, a carpet is laid on the surface, and the carpet is adhered by the adhesive application section 12 on the surface. On the other hand, when the carpet is pulled, the carpet is peeled from the sheet S. At this time, the adhesive force of the adhesive is adjusted so that the adhesive does not stick to the back surface of the carpet.

Since it is ideal that the sheet S does not adhere to the carpet when it is peeled off, it is desirable that the adhesive force on the back surface side be stronger than that on the front surface side. This difference in strength may change the property of the pressure-sensitive adhesive, or may change the area of the applied portion. Furthermore, it may be possible to color-code the front and back sides so that it is easy to determine the color. The sheet S can be peeled off from the panel, and the adhesive is not attached to the panel at this time as well.

The sheet S may be arranged appropriately when the carpet is laid, but it is more effective if the sheet S is arranged in the following correspondence. FIG. 2 is an explanatory diagram thereof,
The sheet S is arranged so as to straddle each floor carpet C at a position where the floor carpets C are butted. That is, the center of the sheet S and the joining point of the carpet C are made to coincide with each other. As a concrete method of laying, the carpet C is first laid, each of the carpets C at the abutting portions is slightly rolled, and the sheet S is arranged so that the center of the sheet S is located at the joining point.

In this case, the adhesive area between the sheet S and one carpet C is smaller than the adhesive area between the sheet S and the panel P (1/4 if four carpets C are butted). When C is peeled off, the sheet S always remains on the panel P side. This phenomenon can be said even if the adhesive strength on the back surface side is made slightly stronger than on the front surface side. Further, according to this method, since the sheet S may be placed at a position where the carpet C abuts after the carpet C is laid, there is no need to mark out the sheet S and the sheet S can be easily pasted. There is also an advantage. Further, it has an advantage that the sheet S can be spared.

[0018]

As described above, since the present invention has been described above, the following effects can be expected. a) Neither the carpet nor the panel has an adhesive on the surface when peeled from the sheet. Therefore, their handling is facilitated. Also, it can be washed and used when the carpet becomes dirty. b) The sheet is economical because it can withstand repeated use. c) By making the adhesive strength of the adhesive on the panel side stronger than that on the carpet side, the sheet does not come when the carpet is peeled off. d) Since no release paper is required, no extra dust is produced and it is economical. e) According to the laying method of arranging the sheets so as to straddle the portions where the carpets are butted against each other, only the carpet can be reliably peeled off, and the laying work can be performed efficiently.
