2. Description of the Related Art A floor finishing material comprises a surface finishing layer made of synthetic resin or carpet and a backing layer, and is used in a long shape or a tile shape. Usually, when laying and installing such floor finishing materials, apply a synthetic rubber latex-based or acrylic emulsion-based adhesive or pressure-sensitive adhesive on the floor surface or backing part and fix the floor finishing materials on the floor surface. ing. Further, a construction method using a double-sided adhesive tape instead of such an adhesive or a pressure-sensitive adhesive is also known.
However, when it is necessary to replace the floor finishing material, adhesive or adhesive remains on the floor surface and the back surface of the floor finishing material, which makes cleaning the floor surface difficult and stacking the picked floor finishing materials during transportation. There is a drawback in that the adhesive or the adhesive migrates to the surface finishing layer.

On the other hand, in Japanese Patent No. 2543432, a non-slip sheet having a non-slip sheet coated with an anti-slip agent such as polyurethane resin on a mesh fabric made of synthetic fibers such as polyester, acrylic, nylon and polypropylene is laid, Then, a laying method is described in which a plurality of tile carpets are not directly fixed or temporarily attached to the upper surface of this non-slip sheet with an adhesive or the like, and a non-slip sheet is interposed therebetween. Further, it has been shown that it has an excellent effect that it is possible to prevent a joint gap and jumping up at a joint between tile carpets, and that the tile carpet can be removed and attached very easily.

The first aspect of the present invention is to form a synthetic resin thin film layer on the surface of a cement-based base, and then lay a net-like material to which an adhesive is adhered, on which a floor finishing material is applied. The present invention relates to a method for laying a floor finishing material, which is characterized by laying a floor. According to a second aspect of the present invention, in claim 1, when the synthetic resin thin film layer is formed on the cement-based underlayer surface, 1 cc of water is dropped on the cement-based underlayer surface after the synthetic resin thin-film layer forming process. The floor finishing material laying method according to claim 1, wherein the water droplets can be held for 10 seconds or more. A third aspect of the present invention is that, in claim 1 or 2, when the cellophane adhesive tape is attached to the cement-based substrate surface after the synthetic resin thin film layer forming treatment, the adhesive force is 0.6 N / cm or more at room temperature. It relates to a method of laying a floor finish according to claim 1 or 2, which has a performance.

FIG. 1 is a sectional view of a floor structure formed by the method of laying a floor finishing material according to the present invention. The floor finishing material 3 composed of the surface finishing layer 1 and the backing layer 2 is a net-like material 4 to which an adhesive is attached and a synthetic resin thin film layer 5.
It is laid on the cement-based base 6 such as concrete or mortar via the. The surface finish layer 1 may be made of synthetic resin or carpet. The surface finish made of synthetic resin is not particularly limited as long as it is used as a surface layer of a normal floor finish. The synthetic resin sheet may have a transparent layer on the front surface or a foamed layer on the back surface. As the surface finishing layer made of carpet, there may be mentioned a carpet raw sheet in which fibrous piles are planted on a base fabric as it is, or a synthetic resin layer for sealing or a backing layer provided on the back surface thereof. The backing layer is usually composed of a natural or synthetic rubber layer or a synthetic resin layer. As the net-like material, a plain woven cloth formed of synthetic fibers such as glass fiber, polyester, acrylic resin, polyamide, etc. and having an interval of about 3 mm is used. As an adhesive,
Rubber-based, acrylic-based, silicone-based viscoelastic polymers, rosin-based, petroleum resin and other tackifying resins, softeners, fillers, anti-aging agents, cross-linking agents, if necessary, Tack, which is said to be three elements of adhesive, adhesive strength,
It is blended in consideration of holding power.

As a method of attaching an adhesive to a net-like material, an organic solvent solution or emulsion comprising an adhesive composition containing a rubber-based, acrylic-based or silicon-based viscoelastic polymer is added to glass fiber, polyester or acrylic. resin,
A net-like material formed of synthetic fibers such as polyamide may be dipped and dried, or the organic solvent solution or emulsion may be applied onto the net-like material with a brush. Then, these adhesives may be uniformly attached to the entire surface of the net-like material, or may be attached to a part of the net-like mesh.

The synthetic resin thin film layer 5 formed on the cement-based base 6 is a solvent-based concrete paint such as vinyl chloride-based, methacrylic-based, or chlorinated rubber, vinyl acetate-based, acrylic-based on a cement-based substrate such as concrete or mortar. It is formed by applying an emulsion type concrete coating material such as styrene-butadiene system and drying. The solvent-type concrete paint or emulsion-type concrete paint having a solid content of 10 to 60% by weight, preferably 20 to 50% by weight, is used. The coating amount to that cementitious underlying, 50 to 300 g / ^{m 2,} preferably from 100 g / ^{m 2.} The number of times of application is not limited to once. In particular, the solvent-based paint is preferably an epoxy-based paint, and the emulsion-based paint is preferably an acrylic-based paint. Thus, the problems such as the insufficient adhesion of the adhesive net due to the fine pores and fine powder existing on the surface of the cement-based substrate 6 are solved, and the brittle surface of the cement-based substrate is strengthened and Since the fine pores and fine cracks existing on the surface of the floor are completely covered with the synthetic resin thin film, it is possible to prevent the infiltration of carpet cleaning water and sewage after laying the floor finishing material. It is also possible to prevent a bad odor caused by.

The synthetic resin thin film layer formed on the surface of the cement-based base 6 is 1 when 1 cc of water is dropped.
It is preferable that water droplets can be held for 0 seconds or more.
This water drop holding time of less than 10 seconds means
The micropores and fine cracks still present on the surface of the cement-based substrate are not sufficiently blocked by the synthetic resin thin film, or fine powder is present on the synthetic resin thin film, and the net-like material becomes the cement-based substrate. It means that it cannot be fixed sufficiently tightly.

For the synthetic resin thin film layer formed on the surface of the cement-based base 6, a cellophane adhesive tape having a width of 24 mm which satisfies the performance of JIS Z-1522 is attached,
When peeled off in the direction of 180 degrees by the method according to ISZ-0237-8, it is preferable that the adhesive strength is 0.6 N / cm or more at room temperature. If the adhesive strength is less than this, the net-like material will move when the floor finishing material is replaced, making it difficult to lay a new floor finishing material. Apply paint or emulsion solvent-type concrete paint so that the adhesive strength is 0.6 N / cm or more.

[0011]

According to the method of laying a floor finish of the present invention, an adhesive net can be used for cement-based substrates such as concrete and mortar, and it is possible to lay the floor finish and remove the floor finish from the substrate. It has become easier, and it is extremely easy to recycle and use floor finishing materials.
