DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing an inorganic plate. More particularly, the present invention relates to a method for producing a cement-based inorganic plate, which is useful as an exterior material, a ceiling material, and the like, and which can be easily and easily subjected to joint treatment, and has a surface material implanted therein.

[0002]

2. Description of the Related Art Conventionally, cement-based inorganic plates have been used as building materials such as exterior materials for houses and ceiling materials. As for this cement-based inorganic plate, various types having excellent properties such as heat insulating properties and sound insulating properties have been known so far, and the appearance of the cement type inorganic board has been upgraded. Precast plates having various surface patterns and shapes have also been developed. Above all, with the saving of construction and the upgrading of buildings, the demand for implanted products into which surface materials such as tiles and stone materials are implanted has been increasing, and has reached 90% of precast plates. Such an implanted product is generally manufactured by a process including the following procedure as shown in, for example, FIG.

(A) First, a desired surface material (a) such as a tile or a stone material is arranged inside a mold (a). (B) Next, an aggregate such as silica sand or an additive is mixed into a cement component such as ordinary Portland cement, and a cement slurry (c) adjusted to a predetermined specific gravity is injected.

(C) After curing and curing, a mold (a)
To obtain an inorganic plate (d) having a surface material (a) such as a tile or a stone on the surface. As described above, when a tile, a stone material, or the like is used as a surface material, the surface durability generally becomes semi-permanent,
It also contributes to improving the asset value of the building. In addition, driving surface materials such as tiles and stones at the time of manufacturing an inorganic plate is more reliable in terms of interfacial adhesiveness and superior in quality stability as compared with a case where the surface is attached to an inorganic plate after attaching it. There are advantages.

[0005]

However, in the conventional method for manufacturing a cement-based inorganic plate as illustrated in FIG. 2, for example, a surface material (a) is formed inside a mold (a) in the manufacturing process. It is necessary to arrange the joints and to perform joint processing of the joints, and these operations are very troublesome. For this reason, there is a limit in improving the productivity of the cement-based inorganic plate (d) into which the surface material is implanted.

In order to solve such a problem, in recent years, a tile sheet with joints which makes joint treatment simple or unnecessary has been developed. In practice, the complexity of construction is not eliminated. The present invention has been made in view of the above circumstances, and solves the drawbacks of the conventional method of manufacturing an inorganic plate, and provides an improved surface material implantation cement that can easily and easily perform joint treatment. It is an object of the present invention to provide a method for producing a base inorganic plate.

[0007]

In order to solve the above-mentioned problems, the present invention arranges a desired surface material in a mold, then sprays a water-absorbing polymer on the joint, and applies water. After swelling, a resin-based clear is applied on this, it is formed into a film, and then a cement slurry is injected and cured and released from the mold. provide.

[0008]

According to the present invention, joint processing is facilitated by using a water-absorbing polymer and resin-based clear for joint formation, and various joint patterns can be easily handled.

[0009]

Next, an embodiment will be described with reference to the drawings, and the method for producing an inorganic plate of the present invention will be described in more detail. FIG. 1 is a process sectional view showing one embodiment of the method for producing an inorganic plate of the present invention.

For example, as shown in FIG. 1, in the method of manufacturing an inorganic plate according to the present invention, <a> First, a mold (1) is set, and a desired surface such as a tile or a stone is set on the inner bottom thereof. Material (2) is arranged. The arrangement of the surface material (2) may be an arbitrary one such as a straight joint pattern or a joint pattern having a feeling of split stone.

<B> Next, a water-absorbing polymer (4) is sprayed on joints (3) of the surface material (2), and water (5) is applied to swell it. The type of the water-absorbing polymer (4) is not particularly limited, and may be any of starch, cellulose, polyvinyl alcohol, acrylic, and the like. The shape may be an appropriate shape such as a granular shape or an irregular shape.

<C> The joint (3) of the surface material (2)
Filled with swollen water absorbing polymer (6). From above, a resin clear (7) such as an acrylic emulsion clear is applied to form a film. <D> Thereafter, an aggregate such as silica sand or an additive is mixed with a cement component such as ordinary Portland cement, and a cement slurry (8) adjusted to a predetermined specific gravity is injected to perform a predetermined curing.

<E> After the cement slurry (8) has hardened, the mold (1) is removed from the mold, and a cement-based inorganic plate (9) having a surface material (2), such as a tile or a stone material, on the surface thereof is implanted. Get. Thus, in the production method of the present invention, joints are given to the surface at the same time as the production of the inorganic plate (9) by using the water-absorbing polymer (4) and the resin clear (7) such as acrylic emulsion clear. Therefore, the joint processing is remarkably simple and easy as compared with the related art. Even when an arbitrary joint pattern such as a straight joint or a pattern having a feeling of split stone is formed, the processing is simple and easy. The productivity of the inorganic plate in which the surface material such as a tile or a stone material is driven is improved. Moreover, since the joint part (3) is covered with the resin film, deterioration of the surface due to air, moisture and the like is prevented, and the durability of the inorganic plate (9) is improved.

Of course, the present invention is not limited by the above examples. It goes without saying that various aspects are possible for details such as the type of water-absorbing polymer, resin clear and surface material, components and mixing ratio of cement slurry.

[0015]

As described above in detail, according to the present invention, it is possible to easily and easily treat joints of surface materials such as tiles and stones. It is also possible to correspond to an arbitrary joint pattern.
