Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double-sided adhesive that has been fixed when disassembling / separating members by peeling off wall finishing materials and floor finishing materials for maintenance and reforming in the field of housing / construction materials. The present invention relates to an interior laminated body that is preferably applied to an application that requires removability such as removing a foam tape from an adherend, and a method for manufacturing the same.

[0002]

2. Description of the Related Art In the field of housing and building materials, it is known that an adhesive and a double-sided adhesive foam tape are used together when fixing an interior material. As a method like this,
For example, there has been proposed an adhesion method in which a decorative plate is fixed to a base material with a double-sided adhesive foam tape and is permanently fixed with a solventless mastic type adhesive (Japanese Patent Laid-Open No. 4-312671). Foam-based adhesive tapes are more suitable than non-woven-based adhesive tapes because they are easier to deal with unevenness of the base, unevenness, rough surfaces, and undulations of members. At the time of remodeling work for repairing dirt and scratches over time, and at the time of maintenance work inside the structure, it is necessary to peel off the interior finishing material.

However, it is necessary to clean the surface of the base material because the interior material is broken at the time of peeling and fragments are left on the base material, or the foam remains when the double-sided adhesive foam tape is used together. there were. Since a strong adhesive was used, the base material was often damaged by skelton, and this required replacement of the base material, resulting in enormous efforts.

In view of this, Japanese Patent Application Laid-Open No. 2000-303041 proposes a double-sided pressure-sensitive adhesive tape which is made of a non-woven fabric as a base material and is excellent in removability without cutting or adhesive residue during peeling. However, this double-sided pressure-sensitive adhesive tape requires a base material having excellent tensile strength, and it is difficult to cope with the base material having flexibility.

[0005]

SUMMARY OF THE INVENTION In view of the above problems, the present invention uses a double-sided pressure-sensitive adhesive foam tape generally used in the construction of conventional interior materials, but when the interior finishing material is peeled off. (EN) Provided are an interior laminated body and a method for producing the interior laminated body, which allows easy maintenance and reforming work because the double-sided adhesive tape can be easily removed from the interior base material.

[0006]

The interior laminate according to the invention of claim 1 of the present application (hereinafter referred to as the first invention) is an interior base material, a single-sided adhesive tape, a double-sided adhesive foam tape and an interior finishing material. Are laminated in this order.

The invention according to claim 2 of the present application (hereinafter referred to as the second
The method for producing an interior laminate, which is the invention), comprises applying a single-sided adhesive tape to one surface of an interior base material, and forming a foam on the back surface of the one-sided adhesive tape and using a double-sided adhesive layer on both sides thereof. It is characterized in that the interior finishing material is attached via an adhesive foam tape.

The present invention will be described in detail below. The interior laminate of the first invention has a structure in which an interior base material, a single-sided adhesive tape, a double-sided adhesive foam tape and an interior finish material are laminated in this order.

Examples of the interior base material include gypsum board, structural plywood, particle board, wood fiber board,
Mortar, concrete, steel frame, damping rubber sheet, etc. are used.

The above-mentioned one-sided adhesive tape has a pressure-sensitive adhesive layer formed on one side of a substrate, and examples of the substrate include thermoplastic resin films such as polyolefin resin, polyethylene terephthalate resin and polyurethane resin; Nonwoven fabrics, woven fabrics, and net-like materials obtained by fiberizing these resins; nonwoven fabrics with high tensile strength of cellulose such as Manila hemp and Japanese paper are used. In addition, it is preferable to use a resin film base material in order to prevent the base material from tearing during peeling.

The pressure-sensitive adhesive for the above single-sided pressure-sensitive adhesive tape is, for example, an organic solvent-based pressure-sensitive adhesive whose main component is a pressure-sensitive adhesive polymer such as acrylic resin, natural rubber, synthetic rubber, or silicone resin; EVA (ethylene- Emulsion-based adhesives containing vinyl acetate copolymer) as a main component; synthetic rubber-based hot-melt adhesives and the like can be used. Among these, it is preferable to use an acrylic pressure-sensitive adhesive that is excellent in durability and removability and has less stains during handling. Moreover, the thickness of the pressure-sensitive adhesive layer is preferably about 20 to 100 μm.

The back surface of the above-mentioned one-sided adhesive tape is usually subjected to a release treatment with a non-silicone resin-based release agent such as a silicone resin-based or long-chain alkyl group-containing polymer. Since the double-sided pressure-sensitive adhesive foam tape is laminated on the back side of the pressure-sensitive adhesive tape, it is preferable to use a single-sided pressure-sensitive adhesive tape that has not been subjected to a release treatment. By using such a single-sided adhesive tape, it becomes possible to secure a predetermined initial adhesive force and permanent adhesive force.
Examples of commercially available one-sided pressure-sensitive adhesive tapes on the back side of which the release treatment is not performed include surface protection tapes (“# 6328-B” manufactured by Sekisui Chemical Co., Ltd.) and electrical insulation tapes (Sekisui Chemical Co., Ltd.). Manufactured by “# 31”) and the like.

The double-sided pressure-sensitive adhesive foam tape is used for fixing an interior finishing material, which will be described later, and uses a foam made of polyolefin resin, polyurethane resin, synthetic rubber resin or the like as a base material, and has both surfaces thereof. A pressure-sensitive adhesive layer is laminated on, and a release paper is further laminated on the pressure-sensitive adhesive layer. As the pressure-sensitive adhesive, the same pressure-sensitive adhesive as the above-mentioned one-sided pressure-sensitive adhesive tape can be mentioned. As the release paper, for example,
Examples include kraft paper, semi-bleached paper, high-quality paper, glassine paper, synthetic resin (polyethylene, polyester, etc.) film as a base material, the surface of which has been subjected to silicone release treatment. Examples of commercially available double-sided pressure-sensitive adhesive foam tapes include double-sided pressure-sensitive adhesive tapes (“# 532S” and “# 538” manufactured by Sekisui Chemical Co., Ltd.).

The interior finishing material is a surface member such as a floor, a wall or a ceiling. For example, a floor finishing material such as a flooring or a cushion floor; a wall finishing material such as a non-combustible decorative board on which a decorative sheet is laminated or cosmetically printed. A ceiling finishing material and the like.

Next, a method of manufacturing the interior laminate of the second invention will be described with reference to the schematic sectional view shown in FIG. In the above-mentioned manufacturing method, after the single-sided adhesive tape 2 is attached to one surface of the interior base material 1, the double-sided adhesive foam tape 3 is attached to the back surface of the single-sided adhesive tape 2, and the double-sided adhesive foam tape 3 is further interior-coated. By laminating the finishing material 4, an interior laminated body is obtained.

In the above-mentioned method for manufacturing an interior laminate, a double-sided adhesive foam tape 3 is previously attached to the back surface of an interior finish material 4, and a single-sided adhesive tape 2 is provided on one surface of the interior base material 1.
May be laminated in advance. As the interior base material 1, the single-sided adhesive tape 2, the double-sided adhesive foam tape 3, and the interior finish material 4, the same materials as in the first invention are used.

Further, FIG. 2 is a diagram (in other words, a sectional view of construction) for explaining a method for manufacturing an interior laminate suitably used as a floor material. As shown in the schematic cross-sectional view in (a), as the double-sided pressure-sensitive adhesive foam tape 3, pressure-bonding in which a non-tacky or slightly tacky masking member 5 is partially laminated on one pressure-sensitive adhesive layer 3a. By using the double-sided pressure-sensitive adhesive foam tape 3 of the mold, it is possible to perform a delicate position adjustment when the interior finishing material 4 is attached, so that it becomes possible to perform joint alignment, tongue fitting, etc. The construction of 4 can be finished beautifully. When the interior finishing material 4 is aligned with the masking member 5 and then pressure is applied from the interior finishing material 4 side or the interior base material 1 side, the masking member 5 is compressed and deformed and the adhesive of the double-sided adhesive foam tape 3 is adhered. Since it is on the same plane as the layer 3a, the double-sided adhesive foam tape 3 and the interior finishing material 4 adhere to each other as shown in the schematic cross-sectional view of FIG.

The position of the masking member 5 may be on the side of the interior base material 1 or the side of the interior finish material 4 of the double-sided adhesive foam tape 3.

It is preferable that the masking member is attached so as to protrude from the surface of the pressure-sensitive adhesive layer and cover 13 to 50% of the entire surface of the pressure-sensitive adhesive layer. By attaching the masking member, the adhesive layer is prevented from being initially attached to the base material, and a good alignment function is exhibited. Further, in the case of a masking member having a coverage of less than 19% of the entire surface of the pressure-sensitive adhesive layer, a sufficient alignment function cannot be exhibited, and the pressure-sensitive adhesive layer surface can be adhered with a minute pressure bonding force. It will adhere to the body. On the other hand, when the coverage is more than 50%, the adhesion area is insufficient and sufficient adhesion cannot be obtained, resulting in deterioration of durability.

The maximum thickness of the masking member is 3
0 to 500 μm is preferable. If the maximum thickness is less than 30 μm, the masking member will be buried below the surface of the adhesive layer with a small pressure, and it will not be able to perform a sufficient alignment function, and if it exceeds 500 μm, even if sufficient pressure bonding is performed by stepping or the like. However, it becomes difficult for the masking member to be buried in the surface of the pressure-sensitive adhesive layer, and sufficient adhesive force cannot be obtained.

As the non-adhesive masking member, a net-like body in which natural or synthetic fibers or metal fibers are woven, a net, a split cloth, a woven cloth, a non-woven cloth or the like can be used. Further, as the slightly tacky masking member, the one obtained by coating the surface of the non-tacky masking member with the slightly tacky adhesive can be used. As the slightly tacky pressure-sensitive adhesive, pressure-sensitive adhesives used for surface protection tapes and the like can be used, and examples thereof include rubber-based, acrylic-based, ethylene-vinyl acetate copolymer (EVA) -based pressure-sensitive adhesives. Further, as other special removable adhesives, acrylic microsphere adhesives, polyoxypropylene adhesives and the like can be used.

A preferred foam substrate for laminating the above masking members has a 50% compressive strength of 0.9 to 290.
N / cm ² . If the pressure is less than 0.9 N / cm ² , the masting member will be deformed by a small pressure, so that the positioning cannot be sufficiently performed, and if the pressure is 290 N / cm ² or more, the masking member will not be deformed even when sufficient pressure is applied due to stepping or the like. ,
Sufficient adhesion cannot be obtained.

(Function) In the interior laminate of the present invention, a single-sided adhesive tape is attached on the surface of the base material, and a foam is used as a base material and an adhesive layer is laminated on both sides of the foam on the back surface of the single-sided adhesive tape. Since the interior finishing material is attached via the double-sided adhesive foam tape, even if the foam base material of the double-sided adhesive foam tape remains when the interior finishing material is peeled off, the residue remains Since it is on the back surface of the single-sided adhesive tape that is previously attached to the surface of the interior base material, it can be easily removed by peeling it off together with the single-sided adhesive tape. Also,
When applying a new interior finishing material, it is possible to easily replace the interior finishing material by attaching the single-sided adhesive tape to the surface of the interior base material and then fixing the interior finishing material via the double-sided adhesive foam tape. Is possible. Furthermore, by using a pressure-sensitive adhesive double-sided adhesive foam tape in which a non-adhesive or slightly adhesive masking member is partially laminated on one adhesive layer, the position of the interior finishing material can be freely adjusted before crimping. The interior finishing material can be attached beautifully as it can be adjusted.
