Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a base material under a curved tile obtained by easily constructing a tiled curved surface of a building.

[0002]

[Prior art]

 In general, as a method of obtaining a tiled curved surface of a building, a curved formwork is assembled after reinforcing reinforcement is poured, ready-mixed concrete is poured in, the formwork is removed after a curing period of several days, and the uneven area is adjusted with mortar. The method is to use a tiled base with a curved tile and then attach the tile with a tile adhesive or tile cement. Such a method is considerably troublesome in the construction method, and therefore requires a long construction time and high cost.

[0003]

[Problems to be solved by the invention]

 The present invention does not require such a complicated construction method in the past, and aims to provide a curved tiled base material capable of obtaining a tiled curved surface with a simple construction.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the curved tile base material of the present invention is a ceramic type inorganic material which can be dry-bendable and is mainly composed of an inorganic hardening component, a fiber, an aggregate, and a hydrate having a flexible structure. It is characterized by providing a synthetic resin coating layer that gives waterproofness and adhesion of tile adhesive on the surface of the board, and can be easily bent according to the curved groundwork of the building. The tile can be directly attached to the wall.

[0005] Conventionally, non-combustible materials to be constructed while bending a curved surface of a building include fiber-reinforced gypsum boards (trade names: FG board and RG board) and fiber-reinforced slag gypsum cement boards. In each case, the board is immersed in water before bending to be absorbed and then bent to remove.

[0006] In comparison with the above, the ceramic-based inorganic plate of the present invention can be bent in a dry state without being immersed in water, and cracks do not occur on the front and back surfaces after bending.

[0007] The ceramic-based inorganic plate in the present invention includes a slag gypsum-based cement plate, a calcium silicate plate, an asbestos slate plate, a wood chip cement plate, a wood wool cement plate, a fiber reinforced cement plate such as GRC and CFRC, and others. Ceramic non-combustible building materials and their asbestos-free base materials can be used.

[0008] As the inorganic hardening component of the inorganic plate raw material, it is possible to use ordinary Portland cement, granulated blast furnace slag, dihydrate gypsum, hemihydrate gypsum, anhydrous gypsum, siliceous raw material, calcareous raw material, and the like. it can.

The fibers of the raw material of the inorganic plate include pulp, wood wool, wood chips, hemp, polypropylene fiber, polyethylene fiber, polyvinyl alcohol fiber, organic fiber such as polyamide fiber, polyacryl fiber, rock wool, glass wool, carbon fiber, various kinds of fibers. Inorganic fibers such as inorganic whiskers and other mineral fibers can be used.

[0010] In addition, as an aggregate of the raw material of the inorganic plate, reactive aggregates such as fly ash, silica fume, diatomaceous earth, perlite, radiolite, sila powder, calcium carbonate, talc, bentonite, sepiolite, zeolite, eddy Non-reactive aggregates such as knight and wollastonite can be used.

Further, calcium hydrate trisulfate hydrate (hereinafter abbreviated as TSH) is most suitable as a hydrate having a flexible structure of the inorganic plate component. It is considered that TSH expresses strength by entanglement between crystals and a filling effect of a void portion in a crystal growth process, and particularly has an effect on bending strength, so that it is considered that dry bending can be performed.

The method for forming the inorganic plate in the present invention may be any of sheet forming (round net type, long net type), compression molding, extrusion molding, molding and the like.

Further, in order to obtain a curved tile base material of the present invention, a synthetic resin coating layer for providing waterproofness and adhesion of a tile adhesive is provided on the surface of the ceramic inorganic plate. The coating film can be obtained by coating a synthetic resin material by a usual method of applying a coating material. Examples of the synthetic resin include acrylic resin, urethane resin, epoxy resin, SBR and other latexes, vinyl acetate resin, and ethylene vinyl acetate. A system resin, vinyl urethane, PVA or the like is used. A flexible resin such as a latex-based resin or an ethylene-vinyl acetate-based resin is preferable from the viewpoint that the substrate is easily cracked without being cracked when the substrate is bent.

As a method of coating, both the waterproof property and the adhesive property of the tile adhesive may be obtained by a single coating layer by one coating, but the coating by two or more coatings may be used. You may make it obtain with a coating film layer more than layers. It is also possible to mix silica sand and other aggregates in these coating resins in order to improve the adhesion of the tile adhesive.

The shape of the curved tile base material of the present invention is as shown in FIG. 1, wherein 1 is a curved tile base material, 2 is a ceramic inorganic plate, and 3 is a synthetic resin coating layer. In order to physically improve the adhesion of the tile adhesive, there is a method of forming an uneven pattern on the surface of the ceramic inorganic plate as shown in FIG.

The thus-obtained curved tile base material is attached with nails or screws while being bent in a dry manner according to the curved base material of the building, and then the tile is attached with a tile adhesive or a tile cement.

[0017]

[Embodiment of the invention]

 Next, the curved tile base material of the present invention will be described in detail with reference to examples and comparative examples.

[0018]

[Example 1] 80 parts of granulated blast furnace slag, 20 parts of dihydrate gypsum, 1 part of slaked lime, 5 parts of asbestos, 5 parts of pulp, 8 parts of pearlite, 10 parts of TSH, 2 parts of organic synthetic fibers, 2 parts of calcium carbonate (average granules) Water was added to a mixture consisting of 3 parts of 3 parts in diameter (2 microns) and 3 parts of calcium carbonate (average particle diameter of 10 microns) to form a slurry, which was formed and dried by a paper machine to obtain a 6 mm thick ceramic inorganic plate. A composition comprising 100 parts of an acrylic emulsion (45% solids) and 60 parts of water was applied to the surface of this plate at a rate of 120 g / m ² and dried. Further, a composition comprising 100 parts of an acrylic emulsion (solid content 45%), 30 parts of silica sand and 300 parts of water was applied thereon at a rate of 120 g / m ² and dried.

[0019]

Example 2 Of the raw materials blended in Example 1, 1 part of microfibrillated cellulose and 2 parts of rock wool were used in place of 5 parts of asbestos, and asbestos of the same dimensions as in Example 1 except for the above. A ceramic inorganic plate was obtained. The same coating as in Example 1 was applied to the surface of this plate.

[0020]

Comparative Example 1 The same coating as in Example 1 was applied to the surface of a commercially available fiber-reinforced gypsum board having a thickness of 5 mm.

Comparative Example 2 The same coating as in Example 1 was applied to the surface of a commercially available fiber-reinforced slag gypsum cement board having a thickness of 6 mm.

Physical properties tests were performed on the respective plate materials obtained in the above Examples and Comparative Examples, and the results are shown in Table 1.

[0022]

[Table 1]

As shown in the table, the plate materials obtained in Example 1 and Example 2 have suitable substrate characteristics as the curved tile base material of the present invention, and the plate materials of Comparative Example 1 and Comparative Example 2 I do not have it. Also in the bending characteristics (indicated by the minimum radius R when bending is performed through three rolls), in Comparative Examples 1 and 2, dry bending is almost impossible and is immersed in water. It retains only the wet bending properties after welding.

[0024]

[Effect of the invention]

 As explained above, the curved tile base material of the present invention can be dry-bent directly to the curved surface of the building at the construction site, and it can be directly tiled with a tile adhesive or the like. It is easy to obtain a tiled curved surface. Therefore, compared with the conventional construction method, the construction period and cost can be significantly reduced.
