[Industrial applications]

 The present invention relates to a stone tile which has a stone surface layer and is easy to apply.

[0002]

[Prior art and its problems]

 A stone panel lined with a resin layer has been conventionally known as Japanese Patent Application Laid-Open No. 4-250254. However, if a floor material with a stone board as a surface layer is made of a sponge sheet or an extremely soft resin layer as a backing layer, for example, if the stone panel is processed and then the stone panel is walked, the stone panel is rather broken. There were some drawbacks. In addition, the dimensional stability of the backing material was poor, which adversely affected the dimensional stability of the entire stone material.

[Means for solving problems]

 SUMMARY OF THE INVENTION The invention of the present application is a solution to the above-mentioned problems, and its gist is a stone tile characterized by having a stone surface layer and a backing layer in which fiber cut pieces and an inorganic filler are densely packed in a synthetic resin matrix. . -2-

In a preferred embodiment, the backing layer projects in the horizontal direction from the stone surface layer, and more preferably, ground resin carpet is used as the backing material.

The present invention will be described below with reference to the drawings. FIG. 1 is a sectional view of a stone tile of the present invention, and 1 is a stone surface layer.

The stone surface layer 1 may be a plate-shaped body of all natural stone, or may be an artificial stone material. The thickness of the stone surface layer is preferably 10 to 25 mm. The stone surface layer is a tile having a side of 300 to 600 mm and a weight of ^{20 to} 70 kg / m ² .

Reference numeral 2 is a resin backing layer having a thickness of 5 to 30 mm. The resin backing layer contains a binder resin 4 and fiber cut pieces 3. As the binder resin, PVC, polyurethane, synthetic rubber and the like are preferable, and a mixture of these resins may be used as long as they are uniformly mixed.

As the fiber cut piece 3, glass fiber, inorganic fiber such as carbon fiber, organic fiber such as polyester, nylon, acryl, wool, vinylon and the like, preferably 3 to 10 mm. The fibrous material is added in an amount of 10 to 30 parts by weight of the backing material, which is the densest packing of the fibers into the vinyl sheet.

The inorganic filler in the resin is mixed in an amount of 50 to 80 parts by weight with respect to 100 parts by weight of the resin, and the inorganic filler is filled in the backing layer at a relatively high density. As the filler, calcium carbonate, talc, barium sulfate and the like are suitable.

In a preferred embodiment of the present invention, crushed granules of synthetic resin lined carpet can be used. Examples of the resin-backed carpet described in the present application include resin-backed tile carpets, carpets, entrance mats, vinyl resin-backed roll carpets, and the like used for the binders. The failed product and the tile punch residue are crushed into raw materials. The crushed carpet is a granular material of 1 to 5 mm square, and nylon, polyester, acrylic and wool are shown as the pile material, polyester nonwoven fabric as the base cloth, and the reinforcing agent in the backing material. Examples thereof include woven and non-woven fabrics of glass fiber, polyester, and vinylon fiber.

The crushed product of the above-mentioned carpet contains fibers cut into 3 to 10 mm, which effectively functions as the tile backing layer component of the present application.

In addition to the carpet, the cushion floor also contains PVC resin and glass fiber cloth, and this crushed product is also suitable as a material. A crushed product of PVC tile can also be used as the raw material.

The granules such as the carpet thus obtained are pressed together with the stone surface layer and integrated under heating and pressure.

In the stone tile obtained above, the backing layer has appropriate elasticity and hardness. For this reason, the backing layer has dimensional stability and the ability to hold the stone surface layer appropriately so that it will not crack when walking or passing heavy objects.

FIG. 2 is a plan view of a stone tile of the present invention, and 1 is a stone surface layer. The backing layer is projected from the side surface of the surface layer 1 by a length of about 1/3 of one side in the horizontal direction from 3 to 7 mm from both ends of the side, and the protruding portion 5 is formed to similarly project from the adjacent surface material 1 '. It closely adheres to the protruding portion 5 ′ of the backing layer and protects the surface materials 1 ′ and 1 from each other. Furthermore, the protrusions 5 and 5'are combined to function as a decorative joint. It can be easily installed just by laying it in this way. -Four-

【Example】

 A stone tile was obtained by laminating a backing layer obtained by heating and pressing the tile carpet ground granules of the standard shown in "Table 1" on a square natural stone surface layer having a thickness of 13 mm and a side of 40 cm.

[0017]

[Table 1] Nylon pile 600 g / m ² Backing layer PVC 18% by weight Plasticizer (DOP) 12 Calcium carbonate 62 Glass fiber cloth 1 PET fiber cloth 1 Nylon fiber cloth 6 The total backing layer is 3000 g / m ² .

The backing layer has a horizontal projection of 5 mm in width, each having a length of 13 cm from the end of one side, and the projection is laid down in close contact with the projection of an adjacent tile. Then, a decorative joint was formed. The stone tile of the present application had appropriate hardness, elasticity, and dimensional stability, and the protrusions protected the side surfaces of the tiles adjacent to each other, and maintained a good construction condition.

[0019]

[Effect of device]

 Construction is easy because it is enough to lay it down.

Since the resin backing layer is densely packed with fibers and inorganic filler, it is excellent in dimensional stability, has high elasticity and moderate hardness, and even if walking or heavy objects pass through stone materials-5- The surface layer did not crack.

Waste such as tile carpet can be reduced and used, which is environmentally preferable.

Since it is not necessary to have difficult leveling and step adjustment, it is possible to carry out the construction even if not a masonry expert.
