る。2. Description of the Related Art Conventionally, when a floor is constructed in a house, a method of fixing a floor surface material made of plywood having a thickness of about 6 to 15 mm to a floor base material using an adhesive has been used. That is, first, an adhesive is applied on the floor base material at predetermined intervals or in a predetermined pattern. Next, the floor surface material is sequentially laminated on the floor base material,
In this case, the floor surface material is stuck on the floor base material while inserting the floor surface material into the groove of the already bonded floor surface material. At the same time as the sticking of the floor surface material, nails for temporary fixing are driven into the fitting portion by the sane at a predetermined pitch.
Thereafter, curing is performed for about 1 to 2 days until the adhesive is cured.

にもなる。However, in the above-described floor construction method using an adhesive, since an organic solvent is used, there is a risk that the working environment may be deteriorated or a fire may be caused.
In addition, since a liquid adhesive is used, there is a tendency that the dispersion of the work is apt to occur, and the peeling or the like may occur due to insufficient adhesive force due to uneven coating. If partial peeling occurs due to insufficient adhesive force, it also causes partial warping of the floor surface material and floor noise.

床下地材表面に対して貼り合わせる。Further, when an emulsion adhesive is used as an adhesive, there is also a problem that moisture permeates into the floor surface material and causes warpage and expansion and contraction. In order to solve the above problems, various floor material fixing methods using a double-sided adhesive tape have been proposed (for example, Japanese Utility Model Publication No. Hei 6-33099, Japanese Unexamined Patent Publication No. Hei 3-241168). In the floor material fixing method using a double-sided pressure-sensitive adhesive tape, the release paper of one pressure-sensitive adhesive layer of the double-sided pressure-sensitive adhesive tape is peeled off and adhered to the floor base material surface or the back surface of the floor surface material. Next, when laying the floor surface material together with the sun, the other release paper is peeled off from the double-sided adhesive tape and bonded to the back surface of the floor surface material or the surface of the floor base material.

There was a problem that the position of the surface material could not be shifted. If a solvent or the like is used to shift the position of the floor surface material, the solvent is impregnated into the adhesive layer of the double-sided pressure-sensitive adhesive tape, the floor base material or the floor surface material, and these are easily deteriorated, and the durability is reduced. . In addition, if the floor material is laid while the other release paper is left to adjust the position, it is difficult to peel off the release paper and adhere the floor surface material to the floor substrate. Become. In addition, the operation of removing the release paper becomes difficult, and the workability deteriorates.

Here, on the surface of the pressure-sensitive adhesive layer, for example, a convex portion made of a solid non-tacky substance such as a mesh is formed,
In the initial state, since the projections only contact the surface of the adherend, the position can be adjusted. After the position adjustment, pressure is applied so that the non-adhesive substance is buried in the adhesive layer, whereby the adhesive layer is bonded to the adherend.

The pressure-sensitive adhesive substance may be buried in the pressure-sensitive adhesive layer, and the position adjustment function described above may be impaired. In addition, when used for the floor fixing method, solid non-adhesive substances are buried in the adhesive layer due to the weight of the floor material or local load due to warpage of the floor material, and the position adjustment function is also sufficient. Could not be fulfilled.

Are laminated, and the non-adhesive or slightly-adhesive masking member 5 is partially laminated on the surface 3 a of the adhesive layer 3. Therefore, when the pressure-sensitive adhesive layer 3 is brought into contact with the adherend without pressing, only the non-adhesive or slightly adhesive masking member 5 comes into contact. Accordingly, the pressure-sensitive adhesive sheet 1 can be shifted in that state. Next, after the position is adjusted, when the pressure-sensitive adhesive type pressure-sensitive adhesive sheet 1 is pressed against the adherend side, as shown in FIG. The inside of the pressure-sensitive adhesive layer 3 moves to the inside from the surface, and the surface 3a of the pressure-sensitive adhesive layer 3 comes into contact with and adheres to the adherend.

必要がある。In the pressure-adhesive pressure-sensitive adhesive sheet, the non-adhesive or slightly adhesive masking member 5 sinks below the surface 3a of the pressure-sensitive adhesive layer 3 due to the local weight of the floor surface material due to its own weight or partial warpage. It is necessary to configure so as not to be inserted. Further, after the pressure bonding operation, the foam base material 2 needs to be configured to have sufficient flexibility so that the masking member 5 can be absorbed below the surface 3a of the pressure-sensitive adhesive layer 3.

きなくなる。In the present invention, from the above viewpoint, the foam base material has a compressive stress at 50% compression of 0.1 to 30.
Those having a range of kg / cm 2 are used. That is, the weight of a fixed-size (303 mm × 1818 mm) floorboard is relatively heavy, usually about 3 to 6 kg. Therefore, if the compressive stress at the time of 50% compression is less than 0.1 kg / cm 2 , the foam base material becomes too soft, and the surface of the pressure-sensitive adhesive layer is changed only by disposing the floor surface material on the floor substrate. It cannot adhere to the material and can not perform the position adjustment function. On the other hand, if the compressive stress at the time of 50% compression exceeds 30 kg / cm 2 , the position adjusting function is achieved, but even if pressure such as stepping is applied after the floor surface material is placed on the floor base material. It is difficult for the adhesive or slightly adhesive masking member to be buried inside the outer surface of the pressure-sensitive adhesive layer, and the floor surface material cannot be securely bonded and fixed to the floor material.

ことが困難となる。The pressure-sensitive adhesive layers formed on both sides of the foam base may be the same or different. In the present invention, the above-mentioned non-adhesive or slightly-adhesive masking member is laminated on at least one of the adhesive layers. The non-tacky or slightly tacky masking member is formed so as to protrude from the surface of the pressure-sensitive adhesive layer and to cover 13 to 50% of the surface of the pressure-sensitive adhesive layer. If the outer surface of the masking member does not protrude beyond the surface of the pressure-sensitive adhesive layer, the position adjusting function cannot be achieved. When the masking member is laminated so as to have a coverage of less than 13% of the pressure-sensitive adhesive layer surface, a sufficient position adjusting function cannot be performed, and the pressure-sensitive adhesive layer surface is applied to the adherend with a small pressure. You will be in contact. Conversely, if the covering ratio of the masking member exceeds 50%, it is difficult to sufficiently adhere and fix the floor surface material to the floor substrate even if the floor surface material is pressed against the floor substrate by stepping on the floor member.

The outer surface of the pressure-sensitive adhesive layer on which the pressure-sensitive adhesive layer and the masking member are laminated is usually covered with release paper. As the release paper, those conventionally used as release papers for adhesive tapes can be appropriately used. For example, kraft paper, semi-bleached paper, woodfree paper, glassine paper, or the like may be used as a base material, and a filler material or the like may be laminated on the surface thereof and then subjected to a release treatment with a silicone-based release agent. Regarding the basis weight of the release paper, if the basis weight is too small, the release paper may be torn when the release paper is peeled off, and if the basis weight is too large, the thickness of the entire pressure-sensitive adhesive pressure-sensitive adhesive sheet increases, so that 50 to 150 g / M 2 is preferred. The thickness of the release paper is preferably in the range of about 70 to 150 μm so that the release paper can be picked up with a fingertip or a nail and easily peeled off.

た。(Preferable Compressive Stress at 50% Compression and Maximum Thickness of Masking Member) As described above, the pressure-sensitive adhesive type pressure-sensitive adhesive sheet used in the floor material fixing method according to the present invention requires no It is necessary to configure the masking member so that it does not sink below the pressure-sensitive adhesive layer surface due to a local load due to its own weight or warpage. Further, after the pressure bonding operation, it is necessary to select a foam so that the masking member is absorbed inside the pressure-sensitive adhesive layer surface. Therefore, the inventor of the present application pays attention to the relationship between the compressive strength of the foam base material and the thickness of the masking member, and as a result of intensive studies, it is preferable that the compressive stress at 50% compression of the foam base material be 0%. In the case of 0.5 to 5.0 kg / cm 2 , the maximum thickness of the masking member may be in the range of 30 to 400 μm, and the compressive stress at the time of 50% compression of the foam base material may be 5.
In the case of 0 to 10 kg / cm 2 , it was found that the maximum thickness of the masking member should be 30 to 100 μm.

なり、接着不良を生じるおそれがある。If the compressive stress at 50% compression of the foam base material is less than 0.5 kg / cm 2 , the foam base material becomes too soft, and the masking member is buried by the weight of the floor surface material. The strength of the foam base material may decrease,
Conversely, if it exceeds 10 kg / cm 2 , the foam base material becomes hard, and it may not be possible to absorb the thickness of the masking member by the pressure bonding operation. As described above, when using a relatively soft foam base material having a compressive stress at 50% compression of 0.5 to 5.0 kg / cm 2 , the masking member easily sinks as described above. In consideration of the surface load of the floor material that is sometimes applied, the maximum thickness of the masking member is preferably 30 to 400 μm, and more preferably 50 to 200 μm. In this case, if the maximum thickness of the masking member is less than 30 μm, the pressure-sensitive adhesive layer tends to come into contact with the adherend and cannot perform a sufficient position adjustment function, and the pressure-sensitive adhesive pressure-sensitive adhesive sheet is formed into a roll. In a wound product, the masking member may sink into the pressure-sensitive adhesive layer. Conversely, the maximum thickness is 4
If it exceeds 00 μm, the foam base material cannot sufficiently absorb the stress at the time of sinking of the masking member, and there is a possibility that poor adhesion may occur.

寸法をいうものとする。On the other hand, when the foam base material has a somewhat hard compressive stress of 50% to 5.0 kg / cm 2 at the time of compression of 50%, the masking member is unlikely to sink during adhesive fixing.
Therefore, the maximum thickness of the masking member is 30 to 100 μm
It is preferable to make it as thin as possible. That is, when the thickness of the masking member exceeds 100 μm, the foam base material is slightly hard, so that even when pressed, the masking member is unlikely to sink into the adhesive layer, and the floor surface material is securely bonded and fixed to the floor base material. You may not be able to do it. If the thickness of the masking member is less than 30 μm, a sufficient position adjusting function may not be achieved even when a relatively hard foam base material is used. Note that the maximum thickness of the masking member refers to the thickness dimension of the largest portion of the masking member.
