BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a speckled pattern raw material used for producing a tile having a speckled pattern.

In particular, it relates to a method for producing a raw material for a tile having a speckled pattern so that the speckled pattern appears clearly and a method for obtaining a material in which the grain diameters of the raw material are averaged.

2. Description of the Related Art Japanese Patent Application Laid-Open No. 7-
There is a method described in Japanese Patent No. 126059. In this conventional example, as described in the same publication, a pattern kneaded material is granulated by a de-sintering machine to obtain a pattern kneaded material in which particles of different sizes are mixed.

Then, the kneaded clay for patterning and the kneaded material to be a base are put into a mixer and granulated while adding water to form a kneaded material to be a base around the kneading material for patterning. And a large agglomerate composed of a layer in which fine particles of the pattern clay are mixed is formed.

Therefore, by using the thus-produced large dumpling-like aggregate as a tile raw material,
One pattern gradually changes from the color of the puddle for pattern to the color of the puddle that becomes the base, and as a result, it is also possible to develop a stepless color tone, and the size of the pattern itself is large as never before. Is being obtained.

Therefore, according to this conventional example, it can be evaluated that a raw material for a spot pattern of a tile having a relatively large particle size can be obtained and a raw material exhibiting a stepless color tone can be obtained.

However, since this conventional example is manufactured by granulating with a de-sinter, it is obviously not expected to obtain a raw material having an average particle size. Also,
Even if it is possible to obtain a raw material that develops a stepless color tone, it is not possible to obtain a raw material that clearly expresses the contour of the spot pattern on the tile.

[0008]

The problem to be solved by the present invention is that, in the conventional example, the tile could not clearly show the contour of the speckled pattern, and the tile raw material having an average particle size was used. It is a point that I could not get.

Therefore, an object of the present invention is to obtain a tile raw material in which the outline of a spot pattern can be clearly expressed, and to obtain a tile raw material with an averaged particle size.

[0010]

The first method for producing a tile raw material of the present invention is to obtain a mixture by adding water to kneaded clay particles, pigment particles and an emulsion, and kneading the mixture. It is characterized in that an extrudate is obtained by kneading with a kneader, a dried product is obtained by drying the extrudate extruded from the kneader, and the dried product is crushed to an appropriate size.

Therefore, since the tile raw material is produced by adding the emulsion in advance and kneading the mixture with a clay kneader, the emulsion of the raw material mass penetrates between the kneaded clay particles and the pigment particles. Are more firmly connected.

Therefore, when the block of this raw material is used as the raw material for the spot pattern at the time of manufacturing the tile, the surroundings of the raw material for the spot pattern do not change and do not change as in the conventional example. Therefore, the contour of the boundary between the kneaded material serving as the base of the tile and the lump of the raw material for the spot pattern can be clearly expressed.

As a result, it is possible to obtain a tile in which a clear speckled pattern is exhibited depending on the size of the speckled pattern.

In the second method for producing a tile raw material of the present invention, water is added to kneaded clay particles, pigment particles and an emulsion to obtain a kneaded product, and the kneaded product is kneaded by a kneading machine. It is characterized in that an extrudate extruded from a kneader is dried through a net provided at an outlet to obtain a dried product, and the extruded product is loosened in water and the loosened product is dried. It is a thing.

Therefore, the mixture obtained by adding water to the kneaded clay particles, the pigment particles and the emulsion is kneaded so that the emulsion penetrates between the kneaded clay particles and the pigment particles.

Then, the mixture is extruded through the net of the clay kneader, so that the extruded product has a cross-sectional diameter corresponding to the size of the mesh of the net, and a flexible thin yarn containing water. It is formed as a thing, and the twisting phenomenon when extruding from the net and the falling phenomenon due to the own weight of the extruded product of the yarn when exiting from the net are waiting for a small amount, but a narrowed portion at regular intervals Is generated while being extruded.

Therefore, the emulsion is dried by drying a large number of yarn extrudates in which the constricted portions are generated at regular intervals, and the kneaded clay particles and the pigment particles are physically bonded to each other to form the emulsion. The liquid is insolubilized by drying.

When the dried extrudate is loosened in water, water permeates into the kneaded clay in the extruded product of the yarn, and the kneaded clay expands. Since the narrowed portion of the object is weak, the narrowed portion changes as a thin layer, and the emulsion of the narrowed portion is broken or broken, so that the extrudate of the yarn is separated into pieces.

Thus, the extrudates are separated, so that it is possible to obtain a material for a mottled mottled pattern having an average particle size within a certain range, although the sizes are slightly different.

Then, the dried raw material for tile in a separated wet state can be dried to obtain a dried raw material. Since the emulsion has been insolubilized in advance, there is no possibility that it will dissolve in water.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a schematic process drawing showing an embodiment of the present invention, and FIG. 2 is an enlarged view showing an intermediate product of a spot pattern raw material showing a state of being extruded through a net of a clay kneader. A substitute photograph, FIG. 3 is a drawing substitute photograph showing an enlarged speckle pattern raw material, FIG. 4 is a drawing substitute photograph showing an enlarged conventional speckle pattern raw material, and FIG. 5 is a speckled spot of the present invention. FIG. 6 is a drawing-substituting photograph showing the front of a tile manufactured using a patterning raw material, and FIG. 6 is a drawing-substituting photograph showing the front of a tile manufactured using a conventional speckled patterning raw material.

First, as the raw material for forming the spot pattern material, commonly used clay particles 10 and pigment particles 12 are prepared, and further an emulsion liquid 14 for binding these is prepared.

Then, water 16 is added to these and kneaded to obtain a kneaded product. Kneaded clay particles 10, Pigment particles 1
2. The mixing ratio of the emulsion liquid 14 and the water 16 is 90% kneaded clay particles, 3% pigment particles, 5% emulsion liquid, and 50% water in weight%. The emulsion liquid used was "Bound Serum" manufactured by Mitsui Toatsu Chemical Co., Inc. Of course, this mixing ratio is only one example of the embodiment.

Thus, the emulsion liquid 14 penetrates between the kneaded clay particles 10 and the pigment particles 12.

Next, in order to sufficiently knead the above-mentioned kneaded material W, the kneaded material W is put into the clay kneader 20 and further kneaded. In this case, it is important to provide a net 22 having a desired mesh size at the exit of the kneader. In other words, the mesh size of the net 22 can correspond to at least the cross-sectional diameter of the spot-shaped raw material.

For example, when a mesh having a size of 30 mesh is adopted, it is possible to obtain a material having a cross-sectional diameter of 30 mesh, that is, a diameter of about 1 mm. Therefore, by changing the size of the mesh of the net 22, it is possible to change the cross-sectional diameter of the spot pattern raw material.

The kneaded material W is extruded from the net 22 of the clay kneader 20. Since the kneaded material W passes through the net 22 when being extruded, the kneaded material W is continuously formed as thin thread-shaped extrudates 24 in a random manner. It will be extruded in the state.

When extruded, a large number of thread-shaped extrudates 24 have a cross-sectional diameter corresponding to the size of the mesh of the net 22, and are extruded as extrudates 24 of flexible thin yarn containing water. At the same time, the twisting phenomenon when extruding from the net 22 and the falling phenomenon due to the own weight of the extrudate 24 are slightly waited for, but extruded in a state where a constricted portion is generated at regular intervals (see FIG. 2). .

Next, the thread-like extrudate 24 in which the constricted portion has been generated is dried at regular intervals.

Thus, the emulsion liquid 14 that has permeated between the kneaded clay particles 10 and the pigment particles 12 constituting the extrudate 24 is dried, so that the emulsion liquid 14 becomes insoluble and is easily broken by a slight impact. It becomes a state.

Then, the innumerable dried string-shaped extrudates 24 are loosened in water 28. The disentangling means is not particularly limited, but it is desired to stir with the stirrer 30 as a means for giving a slight impact.

Thus, the kneaded clay particles 1 constituting the raw material for the spot pattern are loosened in the water 28 by the stirrer 30.
The kneaded clay particles 10 expand due to the water 28 permeating into 0, and at the same time, as described above, the thin constricted portions are formed in the extruded product W at regular intervals, so that the extruded product W is constricted. As a result of the emulsion that adheres to the parts being dried and cracked or broken when the parts are dried, the extrudates W are separated at each constricted constricted part.

Then, the separated product is dried to obtain the raw material S for the spot pattern having the size according to the averaged particle diameter, which is the object of the present invention (see FIG. 5). Here, the average size of the particle size, the cross-sectional diameter is determined by the size of the mesh of the kneading machine, the length, although there are some differences, the narrow constriction of the extrudate described above. It means that the closed portion is determined by being formed at regular intervals.

Of course, in view of the fact that the slight difference in particle size is about 30 mesh in this embodiment, the difference is negligible as a raw material for tiles.

As mentioned above, ignoring the averaging of the particle diameters and kneading the kneaded product with the clay kneader 20 when simply obtaining a raw material for obtaining a clear speckled pattern at the time of use, the kneaded product is obtained. However, it does not pass through the net 22, and the extrudate W may be dried and crushed to an appropriate size in the subsequent step.
