Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for reinforcing ceramic plate materials that are finished by a firing method and other plate materials that are subjected to various high-temperature treatments.

[Conventional technology]

This type of board material is lighter than traditional porcelain tiles and can be manufactured over a large area, so it has been in the spotlight in recent years, especially as a finishing material for buildings. However, when used as a finishing material, the strength of this board is too weak, so how to reinforce this board is a major problem. It had been proposed.

[Problem that the invention seeks to solve]

However, in the conventional method described above, a reinforcing plate is simply glued to the back side of the plate.
In other words, since no reinforcing material is interposed in the middle of the plate material in the thickness direction, a satisfactory reinforcing effect cannot be obtained even though a reinforcing plate body is used.

Of course, it is possible to obtain a satisfactory reinforcing effect by making the reinforcing plate thicker, but a large amount of the reinforcing material itself is required, especially when the plate is made from a new material with the aim of reducing weight. , which had the disadvantage of defeating its very purpose.

The present invention was completed by focusing on such conventional drawbacks, and aims to provide a useful reinforcing method that enables effective reinforcement with a relatively small amount of reinforcing material and is easy to implement. shall be.

[Means for solving problems]

In order to achieve this object, the method for reinforcing a plate material according to the present invention involves interposing a heat-melting synthetic resin in the middle of the plate material in the thickness direction, and melting the synthetic resin by heat treatment of the plate material. It is characterized in that a void is formed in the material, and then a reinforcing synthetic resin is injected into the void and solidified.

[For production]

In this way, reinforcing synthetic resin is injected into the gap formed in the middle of the plate material in the thickness direction and solidified.
After solidification, the reinforcing synthetic resin is located in the middle of the plate material in the thickness direction, and effective reinforcement can be achieved with a relatively small amount of synthetic resin. Furthermore, since the reinforcing material is made of synthetic resin, it does not rust over time, which is also advantageous.

Moreover, in order to form the voids, a heat-melting synthetic resin is simply interposed in the middle of the plate material in the thickness direction and melted, so for example, when the plate material is formed, it may be finished by firing, or other methods may be used. If high temperature treatment is required, the high temperature treatment process can be used as is to easily form reinforcing voids.

〔Effect of the invention〕

As a result, relatively weak plate materials can be easily and effectively reinforced with a small amount of reinforcing synthetic resin, without sacrificing the purpose, especially for plates made of new materials whose purpose is to reduce weight. A durable board material that can also be used for exterior purposes can be obtained.

〔Example〕

Examples of the method of the present invention will be described below based on the drawings.

FIG. 1 shows a cross-section of a finishing material produced according to the invention. (1) is Xonotlite (Xonotlite: 6 Ca0.
This is a plate material whose main component is 6SiOz・H2O). Further, (2) is a glassy glaze layer that is cured after being melted, and (3) is a reinforcing synthetic resin. As will be described later, this plate material (1) is molded after mixing and reacting lime and silicic acid, and it is possible to create a flat plate with a size of about 1 m x 3 m. This finished material is obtained by cutting this plate material (1) into an arbitrary size and shape, applying a glaze to its surface, and final shaping it by firing.

Next, the manufacturing process will be explained.

To briefly explain the manufacturing process of the plate material (1) whose main component is xonotlite, first, water (H2O) is placed in a pot (4).
(A), quicklime (Cab) (B), and silicic acid (S
iOz) Add diatomaceous earth, silica, quartz, etc. as (C) and mix (see Figure 2 (a)). In the pot (4), a hydrothermal reaction occurs between quicklime (1) and silicic acid (C), resulting in a gel-like zonotrite slurry (S) (see Figure 2).
[See 1)). This slurry (S) is put into a mold, pressure is applied with a press (5) to ooze out some moisture, and the plate (1
a) (see Figure 2 (c)).

Two plates (1a) formed in this way are stacked together, and a heat-melting synthetic resin (
6) (see Fig. 2 (d)), and then pressure is applied with a t-press (5) to further exude water and integrate the pieces (see Fig. 2 (n)).

Thereafter, it is dried by blowing hot air at 180° C. to 200° C. in a furnace (7) (see FIG. 2 (f)) to obtain a plate material (1).

Subsequently, this plate material (1) is processed. For example, you can cut it to a desired size, cut it into edges, add a shape to the edge, form a design pattern such as unevenness or grooves on the surface, or even attach it to the back side. Drilling and cutting are performed to fix hardware (see Figure 2 (G)).

Then, after applying glaze to the plate material (1) after this processing (second
(see Figure (H)), final molding is performed at a temperature of 850℃ to 1300℃, and at that time, 850℃ to 1300℃.
The synthetic resin (6) melts due to the high temperature of 300°C, and a mesh-like void (8) with openings on all four sides is formed in the middle part of the plate material (1) in the thickness direction (see Fig. 2). reference).

After that, the plate material (1) is placed in the liquid reinforcing synthetic resin (3).
By soaking the side of the reinforcing synthetic resin (8) and suctioning it upward with a compressor (not shown)
3) (refer to Figure 2 (2)), solidify as is to reinforce the plate material (1), and if necessary, further polish the surface or rework the edges and back surface.

Note that soft vinyl chloride, polyethylene, polystyrene, etc. are suitable as the heat-melting synthetic resin (6) for forming the voids (8). The shape of the heat-melting synthetic resin (6) does not necessarily have to be mesh-like, and various shapes can be used. In addition, synthetic resin for reinforcement (
As 3), polyamide (nylon), polyacecool, ionomer, epoxy, etc. can be used.

Calcium silicate, which is the main component of the plate material (1) that is the base material of the finishing material, includes xonotlite, Nekoite, and Okenite.
It is also possible to use . As the glaze, a non-fired type that can obtain a glassy glaze layer at around 200°C may be used.In this case, there is little risk of performance deterioration due to firing, so the plate material (1) that is the base material As calcium silicate, which is the main component of
ri te) can also be used.

To explain a little about the method of applying the finishing material obtained as above, although it is not shown in the figure, if it is a plate-shaped product with a relatively large area, for example, when applying it to a ceiling surface, general board type As in the case of metal plates, a lightweight steel frame ceiling base, so-called LGS base, may be constructed, and it may be attached to this via mounting hardware attached to the finish. In addition, when installing on a wall surface, it may be attached to a steel structure, LGS base, concrete surface, etc. via mounting hardware, as in the case of general boards or curtain walls.

Furthermore, if it is a relatively small product, for example, when installing it on a wall surface, the back side of the board (1) should be formed with protrusions, grooves, etc. in the same way as porcelain tiles. Similarly, a pressure bonding method may be used, or a method may be used in which the material is pre-attached to a concrete form and poured in the same way as concrete. In addition, when installing on a ceiling surface, it is possible to bury a trigger in the same way as with tiling or masonry, and use a combination of hanging support through this trigger and adhesive support using mortar, adhesive, etc. good.

Although the embodiments of the method of the present invention have been described above, the mode of implementation thereof can be variously modified. For example, in the embodiments described so far, voids (8) are formed by melting the heat-melting synthetic resin (6) during finishing molding by firing, but this synthetic resin (6) is selectively used. By doing so, it is also possible to melt the plate material (1) during drying with hot air at 180°C to 200°C. In the present invention, the heat-melting synthetic resin (
6) The treatment for melting is called heat treatment. Also,
Although two plates (la) are stacked to form one plate (1), a thermofusible synthetic resin (6) is interposed between each plate (la) to form three plates. It is also possible to form one plate material (1) by overlapping the above plates (la).
