DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a tiled board which can be used as an interior / exterior material of a building, an interior material of a tunnel, and a decorative material of a bridge (including a main pole and a railing).

[0002]

2. Description of the Related Art In recent years, there has been a shortage of skilled craftsmen,
Rather than attaching tiles directly to a wall at a construction site, a labor-saving method of attaching tiles to panels and boards at a factory and bringing the attached items to the site to assemble them has become widespread.

One example is a tiled board, but its use is subject to the following restrictions.

[0004] That is, according to the Building Standards Law, in a fire protection area and a semi-fire protection area, a portion of the outer wall of the building where there is a risk of fire spreading must be a fire protection structure.

The fire prevention structure was originally conceived to prevent the spread of fire in a wooden building, and a typical structure of a Japanese-style building is a true-wall structure with earthen-painted walls, and a Western-style structure is a large-wall structure with mortar coating. is there.

According to the Building Standards Law, fire prevention structures are specified,
"It also means that it has the fire-prevention performance specified by a Cabinet Order with a structure such as steel mortar coating or plaster coating."

In addition, if the base material is other than a non-combustible material, it shall pass an outdoor class 2 heating test and an impact test specified in Japanese Industrial Standard A1301 (fire prevention test method for wooden part of building). Is to be certified as fire protection by the Minister of Construction.

[0008] A commercially available asbestos board for exterior has a thickness of 12 mm.
The above board is used as a base.

However, since this tiled board is thick, it is inevitably heavy and bulky.
The handling was poor, and there were problems with stock management and transportation at the stockyard.

[0010] For this reason, in recent years, there has been a demand for making the thickness of the board as thin as about 6 mm and using a thinner tile.

In this case, it is necessary for the entire tiled board including the tile to pass the above test.

[0012] There is a background that the present invention is necessary because a thin board is easily warped.

[0013]

However, the conventional tiled board still has the following problems to be solved.

That is, as shown in FIGS. 10 to 12, the conventional method for manufacturing a tiled board firstly applies an adhesive 51 to the surface of a flat nonporous substrate 50, and then peels off the adhesive. This is performed by bonding a plurality of tiles 53 to which paper 52 has been adhered to a substrate 50 via an adhesive 51, and peeling off the release paper 52 after the adhesive 51 is cured.

By the way, when the adhesive 51 contains air bubbles (especially when the adhesive 51 is polymer cement, it is particularly easy to mix), in the conventional tiled board, the substrate 50 is made of a nonporous material. Since the tiles were also made of a nonporous material and had narrow joints, air bubbles could not escape to the outside.

Therefore, when the adhesive 51 expands during a fire resistance test or an actual fire, the bubbles in the adhesive 51 expand and accumulate at the boundary surface between the adhesive 51 and the tile 53. 53 was to be peeled off from the substrate 50.

An object of the present invention is to provide a tiled board which can solve the above-mentioned problems.

[0018]

According to the present invention, a substrate made of a porous material and having a through hole is adhered to one side surface of tiles arranged vertically and horizontally using an adhesive.
The adhesive was mixed with a composite polymer emulsion containing carboxy-modified styrene butadiene, cyclohexyl methacrylate, and styrene as main components, and a main material containing white cement and silica sand as main components in an amount of 1 part by weight: 3 to 5 parts by weight. The present invention relates to a method for producing a tiled board, wherein a polymer cement obtained by kneading at a compounding ratio is obtained, and the adhesive is cured to obtain a tiled board.

Further, according to the present invention, one side surface of a plurality of tiles is bonded to a release paper, and a substrate made of a porous material and having a through hole is bonded on the other side surface of the tiles using an adhesive. Along with bonding, the adhesive was mixed with a composite polymer emulsion containing carboxy-modified styrene butadiene, cyclohexyl methacrylate, and styrene as main components, and a main material containing white cement and silica sand as main components in an amount of 1 part by weight:
A polymer cement obtained by kneading at a mixing ratio of 3 to 5 parts by weight, and further, after curing of the adhesive, a release paper is peeled from a plurality of tiles to obtain a tiled board. The present invention relates to a method for manufacturing a board.

According to the above configuration, air bubbles can be effectively released from the adhesive to the outside in the manufacturing process, and a tile peeling accident caused by the air bubbles can be reliably prevented.
The substrate and the adhesive can be strongly integrated.

[0021]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be specifically described based on embodiments shown in the accompanying drawings.

First, a tiled board A manufactured by the method for manufacturing a tiled board according to the present embodiment will be described with reference to FIGS.

The tiled board A shown in FIG. 5 has a surface on one side of a flat substrate 10 made of an open-pore porous material.
A large number of tiles 12 are stuck to the base 10a with an adhesive 13 at intervals in the vertical and horizontal directions via joints.

Further, the substrate 10 is provided with a through hole 11, and a structure in which a tile 12 is attached to the substrate 10 is shown in FIGS.

[0025]

As the substrate 10, asbestos cement board, gypsum board, calcium silicate board, slag gypsum board,
A pulp cement plate, a metal plate, a ceramic plate, a synthetic resin plate, or the like can be used.

Further, as the adhesive 13, polymer cement can be used, and for example, an adhesive formed by mixing a composite polymer emulsion P having the following composition and a base material M can be used.

(Composite Polymer Emulsion P) (Example 1) (Example 2) The component weight ratio of the white cement was as follows.

[0029] In addition, mortar obtained by mixing sand and cement can be used in place of the main agent M described above.

Next, a method for manufacturing the tiled board A, which forms the gist of the present invention, will be specifically described with reference to the accompanying drawings.

First, as shown in FIG. 1, a large number of tiles 12 stuck on one side surface of a release paper 30 in the vertical and horizontal directions via joints are placed on a desired work table. On the other side. In addition, a sealing material 31 made of a flexible and elastic rubber or the like is fitted to the joint in advance.

Next, the composite polymer emulsion P was put into a stirring vessel, and the mixture was stirred with a hand mixer while gradually adding the main ingredient M to produce a polymer cement.
As shown in FIG. 2, a constant thickness is applied on the tile 12.

The compounding ratio of the polymer cement is such that the main agent M is 3 to 5 parts by weight with respect to 1 part by weight of the composite polymer emulsion P.
It is desirable to use parts by weight. In this example, the ratio was 1: 4.

The adhesive 13 is applied to the surface 10a of the substrate 10 by spraying, brushing, ironing, or the like. The spraying operation is the most efficient, but in this embodiment, the ironing operation is performed with little loss.

After the adhesive 13 is applied, as shown in FIG. 3, while the adhesive 13 is soft, the substrate 10 made of a porous material having open pores is adhered to the tile 12 via the adhesive 13. Cure until the adhesive 13 is sufficiently hardened.

In this step, since the substrate 10 made of a porous material has open pores, the minute air mixed in the adhesive 13 can be quickly released to the outside through the open pores.

Next, as shown in FIG. 4, the substrate 10 which is strongly integrated with the tile 12 by strengthening the adhesive 13 is inverted so that the substrate 10 is on the bottom and the tile 12 is on the top.

As shown in FIG. 5, the release paper 30 is wetted with water, and then the release paper 30 and the sealing material 31 are removed from the tile 12 to manufacture the tiled board A.

As shown in FIG. 6, if necessary,
The joint after removing the sealing material 31 may be separately filled with a joint material 32 such as white cement, mortar, and polymer cement mortar.

FIG. 7 shows the whole of the tiled board A manufactured by the above-described method, and FIG. 8 shows a state where the tiled board A is attached to the building B. In this embodiment, the building B
A tile-attached board A is attached to the torso of the body using nails.

As described above, in this embodiment, the release paper 30
Adhesive one side surface of a plurality of tiles 12 on the other side surface of the same tile 12, using an adhesive 13, made of a porous material,
A substrate 10 having a through hole 11 on its surface is adhered, and an adhesive 13
After curing, the release paper 30 is peeled off from the plurality of tiles 12 to manufacture the tiled board A. Therefore, in the manufacturing process, the adhesive 13 is effectively used.
Air bubbles can escape to the outside. Further, in a fire resistance test after production or an actual fire, even if residual air bubbles are mixed in the adhesive 13 of the tiled board A, the air bubbles can be effectively released to the outside. In addition, it is possible to reliably prevent the tile 12 from being peeled off due to the expansion of air bubbles.

Also, as shown in FIG.
By providing 11, the following effects can be further obtained.

That is, by utilizing the expansion of the bonding area between the polymer cement (adhesive) 13 and the substrate 10 and a kind of wedge effect,
Strong integration between the substrate 10 and the polymer cement 13 can be obtained.

Accordingly, the tile 12 can be strongly adhered to the substrate 10 through the polymer cement 13, and even if the tile 12 is exposed to a high temperature due to a fire or the like and the substrate 10 expands, the substrate 10 can expand.
Therefore, it is possible to reliably prevent the tile 12 from peeling off together with the polymer cement 13.

The tiles 12 have soles,
As shown in FIG. 5, some tiles 12 have no backing, but any tile 12 can be used because the adhesive force of the polymer cement 13 used as an adhesive is good.

[0046]

As described above, in the present invention, in the manufacturing process, air bubbles can be effectively released from the adhesive to the outside, and the substrate, the adhesive, and the tile can be strongly integrated. So that air bubbles can be effectively released to the outside even in fire tests after production and actual fires, etc.
It is possible to reliably prevent a tile peeling accident caused by air bubbles.
