Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flooring method using a double-sided pressure-sensitive adhesive tape, and more particularly to a flooring material using a double-sided pressure-sensitive adhesive tape. The present invention relates to a construction method in which positioning can be freely performed.

[0002]

2. Description of the Related Art Conventionally, many directly-attached flooring materials, particularly wood-based directly-attached flooring materials, have a flap on a side portion. I was going. If a double-sided adhesive tape is used in place of the conventional adhesive, the simplicity of operation and the reduction of time are remarkably improved, but the adhesive force is so strong that no slipping work can be performed at all. Compared to adhesives, the method using double-sided adhesive tape has excellent advantages such as simplicity of work and the like, so if you dare use double-sided adhesive tape, re-dissolve the adhesive tape surface with an organic solvent and stick. A method of weakening the force, or a method of applying water or an emulsion to the base surface or the surface of the adhesive tape and sliding the emulsion or the emulsion may be considered. In the former method, the initial strength, which is a feature of the adhesive tape, is not obtained, and the flooring material is not easily accommodated.
When an organic solvent is used, the solvent causes pollution. In the latter case, it is necessary to wet the base or the adhesive tape surface with water, and it is only a construction method that can be used only for porous base such as control panel plywood or concrete, and the adhesive strength will not be developed until the water runs out. In addition to the difficulties in the above, a large amount of water remains, which adversely affects the flooring material.

[0003]

SUMMARY OF THE INVENTION The present invention solves the problem of pollution caused by the use of an organic solvent in a conventional construction method.
While maintaining the initial strength development of the adhesive tape, the slashing operation of the flooring material, especially the slashing operation of the wooden flooring material having sane on the side, is improved, and the convergence of the flooring material is improved and the porous material is porous. It is an object of the present invention to provide a method for directly attaching a flooring material, particularly a wooden flooring material, using an adhesive tape that can be applied not only to a base but also to a non-water-absorbing base.

Means for Solving the Problems The present inventors have researched a new construction method which gives a slush function which is a drawback of flooring construction, by making the most of the advantage of using a double-sided adhesive tape.
As a result, when bonding the flooring material and the floor substrate, a double-sided adhesive tape is bonded to either the back surface of the flooring material or the floor substrate surface, and the interface between the other adhesive tape surface and the other adhered surface has a high adhesive strength. By partially interposing a spacer formed of a continuous or semi-continuous foam piece that is easily deformed by light pressure at a foaming rate, contact between the adhesive surface and the adhered surface is prevented, and slippage is enabled. Then, after performing positioning and dimensional adjustment using the shift function, the foam is deformed by pressing, the adhesive surface and the adhered surface come in contact,
I found a construction method that adheres immediately. Further, a tube that can be deformed by light pressure is expected to have the same effect as the foam. Furthermore, the same effect as a foam can be obtained by injecting air into a bag and deforming the shape by removing air, instead of simply deforming the shape by pressure.

Therefore, means of the present invention for solving the above-mentioned problems will be described below. According to the first aspect of the present invention, there is provided a direct bonding method in which a flooring material is directly attached to a floor base surface with a double-sided adhesive tape while arbitrarily aligning the flooring material with a brush. A continuous or semi-continuous foam that is easy to deform under light pressure on the exposed adhesive surface by peeling off the release paper on the other surface of the double-sided adhesive tape on one side in advance After sticking the spacer consisting of one piece and abutting the remaining adhered surfaces of the two adhered surfaces consisting of the back surface of the flooring material and the floor base surface on the adhesive surface on which the spacers were adhered, after aligning the flooring material with a brush, This is a method of directly attaching a flooring material, wherein all the adhesive surfaces are pressure-bonded to a mating surface and directly attached to a floor base surface.

According to a second aspect of the present invention, there is provided a direct bonding method in which a flooring material is directly bonded to a floor base surface with a double-sided adhesive tape while arbitrarily aligning the flooring material with a brush. Peel off the release paper on the other side of this double-sided adhesive tape, and expose the adhesive surface in advance to stand by.On the other hand, place a spacer consisting of a continuous or semi-continuous foam piece that can be easily deformed under light pressure on the floor base surface. The adhesive surface is exposed in advance on the floor base surface on which the spacers are mounted, and the back surface of the flooring material that has been on standby is abutted to align the flooring material with a brush, and then all the adhesive surfaces are pressed against the floor base surface And directly applying it to the floor substrate surface.

According to a third aspect of the present invention, the flooring material is a flooring material provided with a soundproof cushion material on the back surface thereof. is there.

According to a fourth aspect of the present invention, there is provided the method for directly attaching a flooring material according to the first or third aspect, wherein the flooring material is a flooring material whose side surface is subjected to burring.

In the invention of claim 5, the spacer comprises a polyolefin foam, a urethane foam, an acrylic foam, a rubber foam, or the like, and has an expansion ratio of 5 to 100.
A foam piece having a thickness of 1 to 15 mm, preferably a foaming ratio of 10 to 50 times, and a polyethylene foam piece having a thickness of 3 to 10 mm. This is a method of directly attaching a flooring material in the above method.

Preferably, the occupied area of the spacer is 0.5 to 25% of the floor material area, preferably 1 to 5% of the floor material area.
6. The method according to claim 1, wherein the value is 10%.
The method for directly attaching a flooring material in any one of the above means.

To explain the operation of the present invention, the present invention uses a double-sided pressure-sensitive adhesive tape, which could not be used because a strong adhesive force could not be used in the past, by using a spacer made of foam pieces. Is what makes it possible. The pressure-sensitive adhesive surface of the double-sided pressure-sensitive adhesive tape is first brought into contact with the spacer having a thickness without pressing, and the pressure-sensitive adhesive surface other than the spacer contact portion is floated from the mating surface to be directly adhered by the thickness of the spacer. Therefore, the opposite surface of the spacer in contact with the adhesive surface can easily slide on the mating surface, and can be shifted. When the shift to the predetermined position is completed, the spacer made of the foam is compressed by applying pressure, and the thickness thereof is reduced. For example, a thickness of 4 mm becomes a thickness of 0.5 mm. At this time, if the support of the pressure-sensitive adhesive layer of the double-sided pressure-sensitive adhesive tape is made of a foam, the thinned spacer sinks into the double-sided pressure-sensitive adhesive tape, so that the adhesive surface other than the spacer portion is easily applied to the mating surface. It is possible to abut and adhere.

Incidentally, the double-sided pressure-sensitive adhesive tape which can be used in the present invention is not necessarily one in which the support of the pressure-sensitive adhesive layer is a foam, but also a non-woven fabric or a plastic film. With these supports, there is no room for the spacer to sink into the double-sided adhesive tape itself.Therefore, even if the spacer is compressed and thinned, it will have a slight thickness, so the adhesive surface other than the spacer part will come into contact with the mating surface. It is difficult. Therefore, when using a double-sided pressure-sensitive adhesive tape whose support is not a foam, a flooring material having a soundproof cushion material on the back surface is used. The cushion material is polyethylene foam of 3 mm to 8 mm thickness, urethane foam,
It is made of rubber foam or felt. If a flooring material having these soundproof cushioning materials is used, the spacer of the method of the present invention sinks into the cushioning material by compression even on a double-sided adhesive tape of a nonwoven fabric or plastic film support, so that the entire surface of the adhesive surface Can be bonded to the floor base surface. Of course, even if the support is a foamed double-sided adhesive tape, it can be used for a flooring material having a soundproof cushion material. As the flooring material having the soundproof cushioning material, a material in which a back surface of a soundproofing cushioning material that has been bonded to a wood part of the flooring material in advance and a release paper is pasted can be used. The soundproofing flooring material may be either a wooden part and an adhesive processing on the other surface before bonding the cushioning material, or a wooden part and a bonding material on the other surface after bonding the cushioning material.

As can be seen from the above description, the foam spacer needs to have a thickness that floats the adhesive surface of the double-sided adhesive tape during the slashing operation. It is necessary that the film be sufficiently thin when compressed. Therefore, the foam of the spacer of the present invention is a continuous or semi-continuous foam, and the material is:
A foaming ratio of 5 to 1 consisting of a polyolefin foam, a urethane foam, an acrylic foam, a rubber foam, or the like.
00 times, when it is made of a foam having a thickness of 1 mm to 15 mm,
Slippery action and pressure bonding with an adhesive are sufficiently possible. The most preferred expansion ratio is 10 to 50 times, and the thickness is 3 mm to 10 mm.
mm polyethylene foam.

Furthermore, if the size of the spacer, which is a piece of foam, is too large, the adhesive area of the double-sided adhesive tape is reduced so that it cannot be directly adhered to the floor base surface with sufficient strength. On the other hand, if it is too small, it will not be able to function as a spacer and it will not be possible to shift, so the area occupied by the spacer will be 0.5% to 25% of the floor material area.

In the present invention, a plurality of spacers can be arranged in the area of the floor material to be adhered at a distance, and only one corner of the release paper of the double-sided adhesive tape adhered to the flooring material can be partially used. Peel off, stick one or two spacers on the adhesive surface of that part, slide this spacer part in contact with the floor base surface, slide it with release paper for the other parts, perform alignment misalignment, and complete the alignment Then, with the spacer part as a fulcrum, with the flooring material slightly floating, pulling the end of the release paper that was peeled off earlier, peeling off all the remaining release paper, exposing the entire adhesive surface, and then removing the flooring material It is also possible to press and crimp. In this case, 1
Since it is only necessary to use one or two spacers to directly attach a piece of flooring material, the efficiency of direct attachment increases, and the direct attachment is technically easy.
