Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of fixing a skirting board in a building such as a building or a house, and more particularly to a skirting board fixing method which facilitates position adjustment using a pressure-sensitive adhesive type adhesive sheet. .

[0002]

2. Description of the Related Art In a building, a house or the like, a skirting board is fixed to a lower edge of a wall surface along an edge of the wall surface and a floor surface in order to protect the wall surface. The baseboard is made of wood, synthetic resin, or the like, and is fixed to a wall base material using an adhesive.

[0003] That is, in the conventional skirting board fixing method, an adhesive such as a rubber-based adhesive is applied to the skirting board and the wall base surface, dried for a certain period of time, and then the surface to which the skirting board adhesive has been applied. To
The skirting board was fixed to the wall base surface by making contact with the baseboard fixing portion of the wall base surface and applying pressure.

[0004] On the other hand, when a wall base material is formed of a gypsum board or the like, the gypsum board is fixed to a wooden bar using screws or the like. However, there is a case where a wooden bar does not exist at a joint portion of a plurality of gypsum boards. In such a case, a board joint fitting having a T-shaped or L-shaped cross-section between the gypsum boards and having a length along the seam of the gypsum board is inserted. The gypsum board was fixed using screws so as to reach and connected.

However, in a portion where the board joint fitting is inserted, the thickness (2 to 2) of the board joint fitting is required.
(About 3 mm), the thickness of the wall base material increases. Therefore, the flatness of the surface of the wall base material is impaired. Therefore, when bonding the baseboard to the baseboard, after applying the baseboard to the wall base material, apply a batten from the outer surface of the baseboard until the adhesive hardens. It had to touch and press.

[0006]

As described above, in the conventional method of fixing a skirting board using an adhesive, the adhesive is applied to the surface of the skirting board or the wall base material and then dried for a certain period of time, that is, open. The process of securing time could not be avoided. Therefore, there is a problem that the workability is reduced by the amount that the open time must be secured.

Further, the length of the open time must be adjusted according to the seasons such as summer and winter, and if the open time is not set properly, especially in the case of winter etc., poor adhesion may occur. May occur, and the baseboard may peel from the wall base material. Therefore, the open time has to be adjusted according to the season, and the operation is complicated.

In addition, when a solvent type adhesive is used,
The work place was contaminated with the solvent, which could impair the health of workers. Further, the adhesive applied to the wall base material drips, stains the floor surface, and the subsequent cleaning may be complicated.

On the other hand, when the flatness of the part for fixing the baseboard is not sufficient, such as when a plurality of wall base materials are abutted to form a wall base material as in the case of using the board joint fitting, , A complicated work of temporarily fixing using the above-mentioned batten or the like is required, and improvement of workability has been strongly desired.

In addition, since the baseboard is attached along the lower edge of the wall surface along the edge between the wall surface and the floor surface, it is difficult to apply pressure by human hands, and from that point, the workability is also improved. Was difficult to increase.

An object of the present invention is to solve the above-mentioned drawbacks of the conventional skirting board fixing method and to omit complicated work such as adjustment of the open time according to the season and cleaning by applying an adhesive to an undesired portion. It is an object of the present invention to provide a method that can efficiently and reliably fix a skirting board to a wall surface that does not have a risk of contaminating the health of workers and that does not have sufficient flatness.

[0012]

A pressure-sensitive adhesive layer is laminated on both sides of a foam base material having a pressure of 1 to 2.0 kg / cm ² , and is further provided on at least one of the pressure-sensitive adhesive layer surfaces so as to protrude from the surface and on the pressure-sensitive adhesive layer surface. A pressure-adhesive pressure-sensitive adhesive sheet having a non-adhesive or light-adhesive masking member laminated so as to cover 10 to 50% of the pressure-sensitive adhesive sheet is exposed to the outside of the back surface of the skirting board or wall base material. It is characterized by laminating, then laminating a skirting board on the wall base material, and bonding and fixing it by pressing.

It is characterized in that it is bonded and fixed, and the gap between the baseboard and the wall base material is filled with an adhesive solution and solidified.

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the present invention will be specifically described below. It is thought that many of the problems of the conventional baseboard fixing method using an adhesive can be solved by using a dry double-sided adhesive tape. However, in the double-sided pressure-sensitive adhesive tape, when the pressure-sensitive adhesive surface comes in contact with the adherend, the pressure-sensitive adhesive is applied immediately. Therefore, after sticking the double-sided adhesive tape to one of the baseboard and the wall base material, when bonding to the other member, the exposed adhesive layer surface must be brought into contact with the correct position of the other member. Once the adhesive surface has contacted the other member, it has been very difficult to adjust the position.

Therefore, in the skirting board fixing method according to the present invention,
In order to enable the above-mentioned position adjustment, the above-mentioned specific pressure-sensitive adhesive type pressure-sensitive adhesive sheet is used. An example of this pressure-sensitive adhesive type pressure-sensitive adhesive sheet will be described with reference to FIGS. FIG.
1 is a partially cutaway sectional view of an example of a pressure-sensitive adhesive pressure-sensitive adhesive sheet. The pressure-sensitive adhesive type pressure-sensitive adhesive sheet 1 has a structure in which pressure-sensitive adhesive layers 3 and 4 are formed on both surfaces of a foam base material 2 and a non-sticky or slightly sticky masking member 5 is laminated on the surface of one of the pressure-sensitive adhesive layers 3. Having. The non-adhesive or slightly adhesive masking member may be provided on the surface of the other adhesive layer 4.

In the pressure-sensitive adhesive type pressure-sensitive adhesive sheet 1, in the state shown in the figure, a non-tacky or slightly tacky masking member 5 is laminated on the surface of the pressure-sensitive adhesive layer 3 so as to protrude. Therefore, when the pressure-sensitive adhesive type pressure-sensitive adhesive sheet 1 is brought into contact with the surface of the adherend from the side of the pressure-sensitive adhesive layer 3, the pressure-sensitive adhesive layer 3 does not contact the surface of the adherend. Therefore, the position of the pressure-adhesive pressure-sensitive adhesive sheet 1 can be freely adjusted in a state where the pressure-sensitive adhesive sheet 1 is in contact with the surface of the adherend.

As described above, since the non-adhesive or slightly adhesive masking member 5 is present, the pressure-sensitive adhesive type adhesive sheet 1 can be freely contacted with the surface of the adherend from the adhesive layer 3 side. After the position adjustment is completed, the pressure-sensitive adhesive sheet 1 can be stuck by pressing the pressure-sensitive adhesive sheet 1 toward the adherend. .

More specifically, as shown in FIG. 3, the foam base material 2 is compressed and deformed by pressurization, and the non-adhesive or slightly adhesive masking member 5 is provided on the surface 3a of the adhesive layer 3 or on the surface 3a. It will be moved inward from surface 3a. On the other hand, the pressure-sensitive adhesive layer 3 is pressed against the surface of the adherend from the back side of the pressure-sensitive adhesive layer 3 due to the compressive stress in the foam base material 2 generated by pressurization. Therefore, the pressure-sensitive adhesive layer 3 is pressed against the surface of the adherend due to the above-mentioned compressive stress and strongly adhered to the portion other than the portion where the non-tacky or slightly tacky masking member 5 is laminated.

Therefore, in the pressure-sensitive adhesive type pressure-sensitive adhesive sheet 1, position adjustment and re-peeling up to final determination of the sticking position can be easily performed, and after the position adjustment is completed, correct pressure can be obtained by pressing. It can be firmly bonded in place.

In addition, even if a pressure is applied when the pressure-sensitive adhesive type pressure-sensitive adhesive sheet 1 is wound around a roll or the like, the foam base material has flexibility, so that non-adhesive or slightly tacky masking is performed. The member 5 does not sink into the adhesive layer 3. Further, when the foam substrate is pulled out from the take-up roll, the foam base material returns to the original shape by releasing the winding pressure, so that the non-adhesive or slightly-adhesive masking member 5 has the surface of the adhesive layer 3 as shown in FIG. It will be projected again from 3a.

Therefore, the pressure-sensitive adhesive pressure-sensitive adhesive sheet 1 can be provided in a state of being wound on a take-up roll. Even in this case, the performance of the pressure-sensitive adhesive pressure-sensitive adhesive sheet 1 is impaired. There is no.

The foam base material 2 is made of a foam base material having a compressive stress at 25% compression of 0.01 to 2.0 kg / cm ² . That is, the foam base material 2 is made of a flexible foam base material. This is because, as is clear from the explanation of the above principle, when pressure is applied as in the case of pressure bonding, the foam base material 2 is deformed by compression, thereby causing the non-adhesive masking material 5 to adhere to the adhesive layer. 3 and a non-sticky or slightly sticky masking member 5 at the time of pressure bonding.
This is because the pressure-sensitive adhesive layer 3 is pressed against the application position from the back surface of the pressure-sensitive adhesive layer 3 by a compressive stress at a portion other than the portion provided with.

The materials constituting the foam base material include:
It is not particularly limited as long as it can exhibit sufficient flexibility and compressive stress to achieve the above-mentioned effects. For example, a polyolefin-based foam substrate, a polyurethane-based foam substrate, a rubber-based foam A substrate or the like can be used. The foam base may be a closed-cell foam base or an open-cell foam base.
More specifically, examples of the foam base include polyethylene-based closed-cell foam base manufactured by Sekisui Chemical Co., Ltd., trade name: Softlon.

The compressive stress at the time of 25% compression is 1
A foam base material test piece punched into a disc of ² cm ² was laminated to a thickness of about 8 mm, a load was applied from above, and 25%
It is a value measured by measuring the load when compressed.

In the present invention, the compression stress at the time of 25% compression is set to the above range. When the compression stress is less than 0.01 kg / cm ² , the foam base material is too soft and the stress from the foam base material is too low. This is because it is difficult to sufficiently obtain the effect of pressing the pressure-sensitive adhesive layer against the application surface. If the pressure exceeds 2.0 kg / cm ² , the flexibility is not sufficient. This is because it is difficult for the slightly adhesive masking member to be positioned inside the surface of the adhesive layer, and it is impossible to obtain a sufficient adhesive strength. The compression stress at the time of the 25% compression is
Preferably, it is in the range of 0.03 to 1.5 kg / cm ² .

The thickness of the foam substrate is not particularly limited as long as the function of the present invention is satisfied.
1.5 mm. The pressure-sensitive adhesive layers 3 and 4 can be formed using an appropriate pressure-sensitive adhesive commonly used for forming a pressure-sensitive adhesive layer of a double-sided pressure-sensitive adhesive tape. Examples of such an adhesive include acrylic, polyether, urethane, and natural or synthetic rubber-based appropriate adhesives. Among them, from the viewpoint of adhesive strength, an acrylic adhesive is used. Is preferred.

The pressure-sensitive adhesive constituting the pressure-sensitive adhesive layer is preferably one having a gel fraction in the range of 5 to 99% by weight, since both the adhesive force and the cohesive force can be satisfied. In addition, the pressure-sensitive adhesive layer is preferably one having sufficient elasticity so that a non-tacky or slightly tacky masking member can be positioned in the surface of the pressure-sensitive adhesive layer at the time of pressure bonding as described below. A pressure-sensitive adhesive layer having an elastic modulus of 0.1 to 10.0 kg / cm ² is desirable.

The pressure-sensitive adhesives constituting the pressure-sensitive adhesive layers 3 and 4 may be cross-linked by using an appropriate cross-linking agent. Examples of such a cross-linking agent include an isocyanate-based cross-linking agent, an aziridine-based cross-linking agent, and a metal complex. Compounds and the like can be used.

The thickness of the pressure-sensitive adhesive layers 3 and 4 is not particularly limited, and varies depending on the application and the form and thickness of the non-adhesive or slightly-adhesive masking member 5, but is usually about 50 to 100 μm. Is done.

In the structure shown in FIG. 2, the non-adhesive or slightly-adhesive masking member 5 is shaped so as to uniformly and partially cover the surface of the adhesive layer 3. The planar shape of the non-tacky or slightly tacky masking member is protruded from the surface 3a of the pressure-sensitive adhesive layer 3 and is an appropriate shape as long as the pressure-sensitive adhesive layer 3 does not exert the adhesive force before pressure bonding. You. That is, it may be in a lattice shape, or may be constituted by a net or a porous sheet in which openings of circular or other shapes are dispersedly formed.

In the present invention, a non-adhesive or slightly-adhesive masking member is used. However, the material constituting the non-adhesive masking member is not particularly limited, and natural or synthetic fibers and synthetic resins are used. Any material such as metal can be used, and more specifically, the above-described knitted cotton yarn or synthetic resin fiber, a mesh or net made of polyethylene, polypropylene, polyethylene terephthalate, or the like, configured using polyester fiber A nonwoven fabric made of any material such as a metal mesh made of a metal such as brass or stainless steel can be used.

Further, as the slightly adhesive masking member,
Examples of the non-adhesive masking member include a surface having a slightly adhesive pressure-sensitive adhesive. As the slightly tacky pressure-sensitive adhesive, all pressure-sensitive adhesives used for general protect tapes can be used. For example, ethylene-vinyl acetate copolymer (EVA) -based pressure-sensitive adhesives, EVA / SBS (styrene-butadiene-styrene Polymer) -based adhesives, acrylic-based adhesives, rubber-based adhesives, etc. In addition, as special removable adhesives, there are also acrylic-based microsphere-shaped adhesives, polyoxypropylene-based adhesives, and the like. No.

[0033] The slightly tacky acrylic pressure-sensitive adhesive referred to in the present invention has, for example, an adhesive force to a stainless steel plate or an adhesive force to concrete of about 50 to 600 g / 25 mm and a glass transition temperature of -60 to- Those having a temperature of 40 ° C. and a gel fraction of 70% by weight or more are exemplified.

The non-adhesive or slightly adhesive masking member is required to protrude from the surface of the pressure-sensitive adhesive layer at the time of position adjustment at the time of adhering.
It is moved to the surface of the pressure-sensitive adhesive layer and inward of the surface and no longer fulfills its function. Therefore, as long as the above action can be achieved, the thickness of the non-sticky or slightly sticky masking member is preferably thin. For example, when the non-sticky or slightly sticky masking member is formed by gauze, 100 μm or less, non-woven fabric About 3 if configured
It is about 0 μm or less.

When a mesh made of various materials is used, if the mesh is too fine, the pressure-sensitive adhesive does not protrude sufficiently and the bonding area may not be sufficiently secured.
It is preferable to use a mesh as coarse as possible, for example, 10 mesh or less. With metal mesh,
Brass mesh is preferably used because it is inexpensive and easily available.

The ratio of the area of the non-adhesive or slightly adhesive masking member covering the adhesive layer to the area of the entire surface of the adhesive layer, that is, the coverage is 10 to 50.
%. When the coverage is less than 10%, the surface of the pressure-sensitive adhesive layer tends to adhere to the surface of the adherend prior to pressurization even if a non-tacky or slightly tacky masking member is laminated. Re-peeling and position adjustment are difficult. Conversely, if the coverage exceeds 50%, it is easy to adjust the position until the final adhesion, but it is difficult to sufficiently adhere the pressure-sensitive adhesive layer surface to the adherend even when pressure is applied.

Next, an example of the method for fixing a skirting board according to the first aspect of the present invention will be described more specifically. According to the first aspect of the present invention, as shown in a perspective view in FIG. 1, the pressure-sensitive adhesive sheet is used to fix the baseboard 11 to the surface of the wall base material 12. In this case, as the pressure-sensitive adhesive type pressure-sensitive adhesive sheet, either one having a masking member laminated on one surface or one having a masking member laminated on both surfaces may be used. In any case, as shown in FIG. 4, the pressure-sensitive adhesive type pressure-sensitive adhesive sheet 1 is first laminated on the back surface of the baseboard 11. In this case, the pressure-sensitive adhesive sheet 1 is attached so that the masking member 5 is exposed on the outer surface.

Next, the baseboard 11 is laminated on the wall base material 12 shown in FIG. In this case, since the masking member is exposed, the masking member contacts the surface of the wall base material 12 when the baseboard and the wall base material are in contact with each other. 12 can be adjusted. Thereafter, the skirting board is adjusted to an accurate position with respect to the wall base material, and then the skirting board is pressed against the wall base material side, so that the skirting board is attached to the wall base material 12 via the pressure-sensitive adhesive type adhesive sheet. Can be adhesively fixed.

Therefore, since the pressure-sensitive adhesive sheet 1 is used, sagging of the adhesive and environmental pollution due to evaporation of the solvent hardly occur. In addition, since it is not necessary to secure an open time, the working time can be reduced. Furthermore, since the pressure-adhesive pressure-sensitive adhesive sheet provided with the masking member as described above is used, the position can be easily and reliably adjusted.

Therefore, the baseboard 11 can be easily fixed at an accurate position on the surface of the wall base material 12 by a relatively short operation. In contrast to the above, after the pressure-sensitive adhesive type pressure-sensitive adhesive sheet 1 is attached to the wall base material 12 so that the masking member is exposed to the outside, the baseboard 11 is laminated, the position is adjusted, and then fixed. You may.

Next, an example of the skirting board fixing method according to the second aspect of the present invention will be described more specifically. According to the second aspect of the present invention, the pressure-sensitive adhesive type pressure-sensitive adhesive sheet 1 is first laminated on the back surface of the skirting board 11 or the wall base material 12 such that the masking member is exposed to the outside with a smaller area than the skirting board 11. I do. FIG. 5 is a perspective view showing a state in which the pressure-sensitive adhesive type pressure-sensitive adhesive sheet 1 is laminated on the back surface 11a of the baseboard 11. As is clear from FIG. 5, the pressure-sensitive adhesive sheet 1
The masking member 5 has a smaller area than the baseboard 11, and the masking member 5 is exposed on the outer surface.

It should be noted that, contrary to FIG.
The pressure-adhesive pressure-sensitive adhesive sheet 1 may be attached to the wall base material 12 side. Next, the baseboard 11 is laminated on the wall base material 12 (see FIG. 6A). In this case, since the masking member 5 first contacts the counterpart member,
The position can be easily adjusted by moving the baseboard 11 in the plane direction. After the position adjustment, the baseboard 11 is pressed to the wall base material 12 side, whereby the baseboard 11 is temporarily bonded to the wall base material 12 via the pressure-adhesive adhesive sheet 1.

According to the second aspect of the present invention, after the temporary bonding, as shown in FIG. 6B, a gap A between the baseboard 11 and the wall base material 12 is filled with an adhesive solution and solidified. Since the adhesive solution is filled in the gap A between the pressure-sensitive adhesive type pressure-sensitive adhesive sheet 1 and the wall base material 12 to which the pressure-sensitive adhesive sheet 1 is not stuck, the adhesive solution can be effectively adhered in a very small amount, thereby contaminating the worker's health. There is almost no fear.

The adhesive solution is not particularly limited, but a rubber adhesive or the like can be used.
The adhesive solution includes baseboard 11 and wall base material 1.
In order to easily fill the gap A between the two and prevent sagging downward, the viscosity is 10 to 100 poise (20
° C).

The method for filling the adhesive solution is not particularly limited, but may be a method using a filling gun or a tube. Further, in FIG. 5, although one pressure-sensitive adhesive sheet 1 having an area smaller than that of the skirting board 11 is used for the skirting board 11, a plurality of pressure-bonding adhesive sheets 1 are used. May be dispersed and applied to the back surface or the surface of the wall base material 12.

According to the second aspect of the present invention, the gap A shown in FIG. 6B is filled with an adhesive solution. In this case, the gap between the gaps A, ie, the gap between the base material 12 and the baseboard 11 is filled. The interval between the two varies depending on the type and viscosity of the adhesive solution, but it is generally desirable that the interval be about 0.5 to 1.0 mm.

According to the second aspect of the present invention, since the pressure-sensitive adhesive type adhesive sheet 1 is used in the same manner as the first aspect of the present invention, the baseboard 11 is attached to the wall base material 12. Temporary fixing can be reliably performed in a state where it is positioned at an accurate position. In addition, since the adhesive solution is filled and hardened after the temporary fixing, the baseboard 11 can be firmly and reliably fixed to the wall base material 12. In addition, since the amount of the adhesive solution used is small, the health of workers is not contaminated.

Therefore, for example, in the wall base material 12,
If there is a seam using a board joint fitting or the like and the surface of the wall base material 12 is not necessarily flat, the adhesive solution may vary in the gap A between the surface of the wall base material 12 and the baseboard 11. Even so, the baseboard 11 and the wall base material 12 can be securely fixed.

Next, specific experimental examples will be described.

A pressure-sensitive adhesive type in which a pressure-sensitive adhesive layer is formed on both surfaces of a foam base material having a compressive stress at the time of the above-mentioned specific range, and a non-sticky or slightly sticky masking member is further laminated on at least one surface. Since the skirting board is fixed to the wall base material using an adhesive sheet, the skirting board can be easily fixed in the surface direction with respect to the wall base material while the non-adhesive masking member is in contact with the wall base material during fixing. The position can be easily adjusted. Also, after adjusting the position,
The masking member is buried simply by pressing the skirting board against the wall base material side, and the skirting board is securely bonded and fixed to the wall base material via the pressure-adhesive adhesive sheet.

According to the second aspect of the present invention, the pressure-sensitive adhesive sheet is smaller than the area of the skirting board, and the pressure-sensitive adhesive sheet is used as the pressure-sensitive adhesive sheet. As in the invention, the skirting board can be temporarily fixed while easily adjusting the position with respect to the wall base material. Moreover, claim 2
According to the invention described in the above, after the temporary fixing, the gap between the baseboard and the wall base material is filled with the adhesive solution and cured, so that the wall base material and the baseboard can be securely bonded and fixed.

Therefore, for example, even when a seam exists in a wall base material like a seam of a gypsum board and the surface of the wall base material is not always flat, the solidification of the adhesive solution causes the wall base material to be connected to the baseboard. And can be firmly joined.

Further, in the baseboard fixing method according to the first and second aspects of the present invention, the pressure-sensitive adhesive sheet is used as described above, and even if an adhesive is used in combination, the method is limited to a small amount. When the skirting board is fixed at a low position along the edge of the wall surface with the floor, it is possible to shorten the working time because the solvent is less likely to cause environmental pollution and does not require complicated work such as securing open time. Operability can be improved, so that the physical burden on the worker can be reduced.
