Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of applying a three-dimensional pattern to tiles for interior / exterior and floor boards, or ceramics such as ornaments.

[0002]

2. Description of the Related Art Conventionally, as a method of giving a three-dimensional pattern to a ceramic, a press by embossing or a method of blasting by shot with abrasive powder or the like has been known. However,
All of them have the same pattern, and a large number of press dies and masks for blasting are required to make many types of patterns, which increases the cost, and when blasting, it is necessary to remove the mask from the ceramics. It was time-consuming and was not suitable for mass production.

[0003]

Therefore, the present invention adopts a blast having a good finish, but is epoch-making in that it can be mass-produced without the need for a mask and can produce a non-uniform three-dimensional pattern if desired. The present invention provides an inexpensive method for displaying a three-dimensional pattern.

[0004]

Therefore, according to the present invention, after drying a molded ceramic body, a liquid adsorbing to the body is applied in a pattern to the surface of the ceramic body, and while it is not dried, By blasting the surface, only the part where the liquid is not applied is peeled off so that the part where the liquid is applied appears as a three-dimensional pattern. The liquid may be applied with a brush or a brush as water or a pigment solution, or starch paste may be mixed in to improve the adhesion to the ceramic body.

[0005]

[Function] When a liquid is applied to a dried ceramic body, the surface layer of the base material at that portion absorbs water to become a viscous state, and a portion not coated with the liquid maintains a dry state. By blasting, only the base material surface layer in the dry state is peeled off, and the base material surface layer in the viscous liquid application portion remains as it is.

As a result, the liquid application portion has a three-dimensional pattern, and the base material may be dried and fired. The reason why this liquid application part remains even after blasting is that the surface layer of the base material at that part absorbs water and becomes a viscous state, forming a chain body. Was able to survive.

Further, since the pattern of the applied portion of the liquid also changes depending on the amount of water absorption, the portion with a large amount of water absorption does not come off due to blasting, but the portion with a small amount of water absorption with a little application comes off a little by blasting. This causes a blurring part.

When the liquid is a thin pigment solution, the pigment remains as it is and develops color by firing. Therefore, there is no need to paint later. Also, if starch paste is mixed into the liquid to add viscosity, the application site will surely remain, the boundary with the exfoliation part will be clear, and a clear three-dimensional pattern will be formed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the present invention will be described below with reference to the drawings. After drying the tile base 1 shown in FIG. 1, first, as shown in FIG. 2, water 2 is applied in a pattern on the surface of the base 10. In this example, a brush is used to randomly and horizontally apply the paint so that it has a natural pattern. As a result, as shown in FIG.
The application part of the water 2 absorbs water to form the water absorbing surface layer 11 in a viscous state.

Then, sand is blasted for about 10 seconds on the surface of the base material 10 in this state, so that only the dry surface layer 12 in a dry state where the water 2 is not applied is peeled off, and as shown in FIG.
The water-absorption surface layer 11 in the viscous state remains as it is. As a result, the water-absorbing surface layer 11 of the application portion of the water 2 is raised, and the tile base 1 having a three-dimensional pattern as shown in FIG. 1 is obtained. In this case, since the portion where the amount of water 2 applied is small is in a weakly viscous state, it is slightly peeled off by blasting, and thus remains as a blurred pattern.

As described above, according to this example, the water application surface functions as a mask, and a natural three-dimensional pattern can be obtained. Moreover, it is attractive because it is a random pattern and not a uniform pattern. It is easy to obtain different three-dimensional patterns of natural bodies without the need to make and remove masks. The base material 1 having a three-dimensional pattern may be dried and fired. Further, the base material 1 may be put in the baking chamber as it is, and it is dried by hot air and baked, so that it can be mass-produced.

FIG. 5 shows a thin pigment solution prepared by dissolving the pigment in water instead of water and applying a pattern on the surface of the base material with a brush, and in this case also, the surface layer of the coating portion is applied. Absorbs water and becomes viscous, and remains even after blasting. At this time, if different pigments are applied, different colors are developed after firing. That is, in FIG. 5, if the black portion 31, the brown portion 32, and the white portion 33 are used, a flashy pattern can be exhibited. Or if different pigments are applied repeatedly, a unique atmosphere pattern can be obtained.

Although this example is constructed as described above, the present invention is not limited to this. For example, the shape of the base material is not limited, and plates, dishes, etc. other than tiles may be used. Further, the type of liquid applied to the pattern surface is also appropriate, and may be paint or ink. Further, when starch paste is mixed into the liquid, the adhesion to the substrate becomes strong and the adhesive film becomes strong, so that a clear three-dimensional pattern can be obtained without peeling off even with strong blast. The means for applying the liquid is also arbitrary, and in addition to applying with a brush or a brush, application with a roller may be used when the same pattern is obtained.

[0014]

According to the present invention, since the liquid application surface plays the role of a mask, there is no need to manufacture or remove the mask, the work is simple, and the mass production is inexpensive. It is possible to obtain a quaint three-dimensional pattern with an unnatural nature. According to the second aspect, it is possible to easily work because of the use of water. In claim 3, the color pattern is obtained by firing as it is. In claim 4, a strong adhesive film is formed by mixing the starch paste, and a clear three-dimensional pattern is obtained. According to claim 5, a tile having a natural pattern is obtained.
