[0003]
By the way, in recent years, environmental problems have been attracting attention as social problems. From the viewpoint of effective use of limited global resources, substances are more important than conventional social systems based on mass consumption and mass disposal. There is a strong demand for a shift to a recycling-oriented social system. Such requirements are the same in the field of construction materials, and it is necessary to establish technologies for separating and collecting construction materials and using them for recycling.
[0004]
However, in the construction of conventional floor finishing materials, the floor finishing material is firmly bonded to the ground surface using a construction adhesive on the ground material such as concrete slab, mortar or plywood. The existing floor finish material is difficult to peel off at the time of building or demolishing, and if you try to peel it off forcibly, a part of the adhesive or base material adheres to the floor finish material, and the floor finish material is separated and collected for recycling It was difficult to do.
[0005]
In this way, when considering recycling, which can be the ultimate goal of improving environmental problems, it is important how to efficiently separate the used floor finish material from the floor base material for separation and collection. Although it is a problem, there has been no floor finish that directly solved this problem.
[0006]
[Problems to be solved by the invention]
Accordingly, in view of the present situation, the present invention provides a floor finishing material that can be used by efficiently separating and collecting a used floor finishing material from a floor base, separating and collecting the floor finishing material, and the floor finishing material. It is an object to provide a construction method. That is, the present invention provides a floor covering material that can be directly applied to the under floor material without using a conventionally used construction adhesive, and a method for constructing the floor covering material. The issue is to provide.
[0007]
[Means for Solving the Problems]
Therefore, the floor covering material according to claim 1 of the present invention is a floor finishing material comprising a surface layer provided on the upper part of the base material layer and a back surface layer provided on the lower part of the base material. From the base material side, it consists of an intermediate layer made of a medium foam synthetic resin or a non-foamed synthetic resin with an expansion ratio of 4 or less, a printed layer on the intermediate layer, a transparent friction-resistant layer on the printed layer, and the back layer has an expansion ratio 4 or less medium foam synthetic resin layer, non-foam synthetic resin layer, at least one layer of organic fiber non-woven fabric, and the base material layer was provided so as to be located on the surface side from the approximate center of the laminated structure or the center. It is a floor covering material characterized by that.
[0008]
In the floor covering material having such a configuration, the base material layer includes a glass fiber woven fabric, a glass fiber non-woven fabric, a non-woven fabric composed of glass fiber / pulp / organic fiber / binder, other glass mixed paper, inorganic filler paper, Any material can be used as long as it is made of a nonwoven fabric such as a polyester nonwoven fabric, a woven fabric, a knitted fabric or the like and used for a floor finish. By using such a base material as the intermediate layer of the laminated structure, the floor finish material is secured in the horizontal dimension stability, and without having to adhere firmly to the floor base surface using a conventionally used adhesive. The floor finishing material can be installed by placing the floor.
[0009]
In addition, in the floor covering material provided by the present invention, in order to prevent the floor finishing material from slipping or rolling up from the base material due to a local load or a moving load, a dent in the vertical direction is used. The amount should be as small as possible. Therefore, the surface layer is composed of a medium-foamed synthetic resin layer or a non-foamed synthetic resin with an expansion ratio of 4 or less.

Accordingly, generation of mold on the floor finish is suppressed. In addition, the bottom surface of the floor finish, that is, the surface in contact with the ground is also provided with anti-slip properties, so that even if a local load is applied perpendicularly or horizontally to the floor, the floor finish may slip from the ground. , It will not be drowning.
[0015]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, specific embodiments of the floor covering material provided by the present invention will be described with reference to the drawings.
[0016]
FIG. 1 shows a cross-sectional structure of a laminated floor finishing material provided by the present invention. In the figure, 1 is a flooring finishing material provided by the present invention. The basic structure of the material 1 includes a base material layer 2, a surface layer 3 provided above the base material layer 2 so as to have a sandwich laminated structure sandwiching the base material layer 2, and a back surface layer provided below the base material layer 2. 4, the surface layer 3 is an intermediate layer 31 made of a medium-foamed synthetic resin or a non-foamed synthetic resin with an expansion ratio of 4 or less from the base material layer 2 side, a printed layer 32 on the intermediate layer 31, and a printed layer 32. The back surface layer 4 is a floor finish composed of at least one of a moderately foamed synthetic resin layer, a non-foamed synthetic resin layer, and an organic fiber nonwoven fabric layer.
[0017]
In the floor covering material 1 of the present invention, in order to prevent warping in the vertical direction, in particular, warping to the surface side, the sandwiched base material layer 2 has a substantially central portion or a central portion of the laminated structure. It is provided so that it may be located in the surface side more.
[0018]
According to the study by the present inventors, it has been found that the positioning of the base material layer 2 is achieved by satisfying the following relationship.
As one of the methods, the thickness of the back surface layer 4 laminated on the lower part of the base material layer 2 is substantially equal to the thickness of the surface layer 3 laminated on the upper part of the base material layer 2, or Let's be big. That is, the relationship “layer thickness on the front surface side ≦ layer thickness on the back surface side” may be ensured.
[0019]
As a second method, the weight (g / m ² ) of the back surface layer 4 laminated on the lower part of the base material layer 2 is the weight of the surface layer 3 laminated on the upper part of the base material layer (g / m ² ). It should be almost equal to or larger than That may be ensured relationship "layer weight of the surface side (g ^{/ m} 2) ≦ back side of the layer weight (g / ^{m 2)."}
[0020]
In the floor covering material of the present invention, the back layer 4 constituting the sandwich structure (laminated structure) can further have a desired plurality of laminated structures. For example, a moderately foamed synthetic resin layer and a non-foamed synthetic resin layer with a foaming ratio of 4 or less are laminated, or a moderately foamed synthetic resin layer with a foaming ratio of 4 or less and a non-woven fabric / woven fabric / knitted fabric made of organic fibers. It may be a laminate of a moderately foamed synthetic resin layer and a non-foamed synthetic resin layer with an expansion ratio of 4 or less and an organic fiber nonwoven fabric / woven fabric / knitted fabric. The method of laminating each layer is a heat laminating method, a laminating method using an adhesive (in the case of a sheet material that does not absorb the adhesive, an adhesive layer exists between the layers, and an adhesive such as woven fabric, knitted fabric, non-woven fabric, etc. In the case of a sheet material that absorbs, an ordinary lamination method such as bonding with a part of the sheet material in which an adhesive has penetrated can be applied.
[0021]
The synthetic resin used for the front surface layer 3 and the back surface layer 4 is not particularly limited. For example, the synthetic resin used for conventional floor materials, specifically, polyvinyl chloride (PVC). , Acrylic, polyurethane, polypropylene, polyethylene, ethylene-vinyl acetate copolymer (EVA), polyolefins such as ethylene-ethyl (meth) acrylate, and other various thermoplastic resins are used alone or in combination. be able to.
[0022]
In consideration of recycling, it is preferable to use a combination of synthetic resins having good compatibility or the same synthetic resin. Moreover, in these resin components, 3rd components, such as an inorganic filler, an antibacterial agent, and an antifungal agent, can be added as needed.
[0023]
FIG. 2 shows a cross-sectional structure of another layer structure according to the floor covering material of the present invention. In the figure, reference numeral 1 denotes a floor covering material provided by the present invention. The basic structure of the floor covering material 1 is the same as that shown in FIG. In order to obtain a sandwich laminated structure, the surface layer 3 is provided on the upper side of the base material layer 2 and the back surface layer 4 is provided on the lower side of the base material layer 2. The surface layer 3 has an expansion ratio of 4 from the base material layer 2 side. The intermediate layer 31 is made of the following moderately foamed synthetic resin or non-foamed synthetic resin, the printed layer 32 on the intermediate layer 31, and the transparent friction-resistant layer 33 on the printed layer 32. It is a floor finishing material consisting of at least one of a moderately foamed synthetic resin layer, a non-foamed synthetic resin layer, or an organic fiber nonwoven fabric layer of 4 or less. Items 6, 6... Are provided.
[0024]
In this case, in the floor covering material 1 of the present invention, due to the presence of organic fiber non-woven fabric, woven fabric, knitted fabric, etc. on the back side of the construction, and the presence of synthetic resin projections 6, 6,. In addition, the construction surface of the base material and the floor covering material 1 can secure a void without completely adhering to it, so that it does not inhibit the evaporation of moisture from the base material, and the floor finish material is dried. It will not inhibit sex. Accordingly, generation of mold on the floor finish is suppressed. In addition, anti-slip properties are imparted to the bottom surface of the floor finish, that is, the surface in contact with the ground, and even if a local load perpendicular or horizontal to the floor is applied, the floor finish may slip or sag from the ground. It will not go up.
[0025]
In addition, it cannot be overemphasized that the embossing of the groove structure which followed the back surface layer was given instead of installation of a protrusion-like thing.
[0026]
The present invention also provides a method for constructing a floor covering material constructed as described above, and the construction is specifically carried out as follows. That is, a plurality of floor finishing materials are placed and installed adjacent to each other on the construction floor base surface so as not to cause a gap in the joint. The joints of a plurality of floor finishing materials can be processed by cutting with various trimmers having functions such as overcutting, dropping and scribing, which are generally performed with floor finishing materials. And the wall edge part of a floor finish material is cut so that about 0.3-10 mm clearance gap may be formed between wall surfaces. Next, an adhesive tape is applied and fixed to the back side of the contact joints of the floor finishing materials adjacent to each other so as to cover the joints. The reason for providing an arbitrary gap between the wall and the wall is to prevent the floor finish from expanding due to an increase in the room temperature, to prevent the floor finish from generating blisters and wrinkles, and to remove moisture from the foundation. It is a measure for evaporating from the gap. Of course, the smaller the expansion / reduction of the floor finishing material and the smaller the moisture content of the base material, the smaller the gap with the wall surface can be made. And the part near a wall can be covered with a baseboard etc. after construction of a floor finishing material.
[0027]
More specific means of this construction method will be described in detail with reference to FIGS. That is,
(A) After placing and placing the floor covering materials 11 and 12 of the present invention desired to be installed on the floor base 10 adjacent to each other so as not to generate a gap in the joint portion, It cuts so that the clearance gap 16 of about 0.3-10 mm may be formed between wall surfaces (FIG. 3 (a)).
[0028]
(B) Next, the contact joint portions 14 and 15 of the adjacent floor covering materials 11 and 12 are made into double doors (FIG. 3B).
[0029]
(C) Next, only the approximate half width of the single-sided adhesive tape 13 is pasted on the back surface side of the end portion of the one floor covering material 11 that has been spread (FIG. 3C).
[0030]
(D) The floor covering material 11 with the adhesive tape 13 attached is put back on the floor base 10 (FIG. 3 (d)).
[0031]
(E) Thereafter, the other floor covering material 12 is pasted on the adhesive tape so that the end portion thereof and the end portion of the one floor covering material 11 are in close contact with each other (see FIG. 3 (e)).
[0032]
By adopting the above steps, it is possible to easily construct the floor covering material of the present invention. Needless to say, the adhesive tape may be not only a single-sided adhesive tape but also a double-sided adhesive tape.
[0033]
In the construction method of the floor covering material of the present invention, it is possible to carry out after providing an auxiliary sheet on the floor base surface. In this case, the underlay sheet is constructed by the same construction method as that shown in FIGS. 3A to 3E without using an auxiliary sheet, that is, an underlay sheet, on the floor base. An adhesive is applied to the surface of the floor, and a floor covering material is laminated and adhered. The construction method using the underlay sheet is effective when the floor covering material of the present invention is constructed for commercial laying.
Even in the construction of the flooring material using this underlay sheet, the underlay sheet is not adhered to the surface of the floor base, so that the floor base after use is the same as when the floor covering material is used alone. It can be efficiently peeled off, separated, collected and recycled.
[0034]
