DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the method for producing a patterned ceramic molded body of the present invention will be described below with reference to the drawings. Figure 1,
2 and 3 show a pattern-formed ceramic molded body 1 manufactured by the present invention, which is a pavement tile in this case. FIGS. 1 and 2 show a traffic sign pattern, and FIG. 3 shows a pattern pattern.

The tile shown in FIG. 1 comprises a pattern layer 2 and a base layer 3 having the same thickness, and the pattern layer 2 is exposed on a part of the surface of the tile. As will be described later, this tile fills the pattern sintering material in a part of the forest intervals of the standing pieces that stand densely and densely stand in the forest arranged in the formwork, and the remaining part of the forest interval is the base layer sintered material. Was manufactured by filling the same thickness as the above-mentioned sintered material for patterns. On the other hand, in the tile of FIG. 2 as well, the pattern layer 2 is exposed on a part of the front surface of the tile, but the back surface of the tile is formed only by the base layer 3. That is,
The thickness of the base layer 3 is thin in the part that lines the pattern layer 2 and thick in the part exposed on the surface. The tile of this FIG. 2 is filled with the sintered material for pattern in a part of the forest interval of the standing pieces of the forest three-dimensionally arranged densely in a forest as described later, and includes the rest of the forest interval, It was manufactured by filling the remaining portion of the inside of the mold, which did not contain the above-mentioned sintered material for patterns, with the sintered material for base layer. or,
In the tile of FIG. 3, the pattern layer 2 forms the entire front surface, the back surface portion is formed with the base layer 3, and the base layer is not exposed on the surface of the tile. This tile is filled with the pattern sintering material in all the forest intervals of the standing and standing pieces of the forest three-dimensionally arranged in the form as described later, and the pattern sintering material inside the form is It was manufactured by filling the remaining portion not filled with the sintered material for the base layer. It should be noted that the order of filling the sintered material for pattern and the sintered material for base layer is arbitrary in manufacturing any tile.

In the present invention, the base of the ceramic molded body, in which the pattern layer 2 is exposed on a part or the whole surface as illustrated in FIGS. 1, 2 and 3, is supported by the mold 4 and the support. Using the forest solid 5 in which standing pieces are densely gathered from the surface of the timber,
The pattern layer 2 is a dry sintered material for a pattern, and the base layer 3 is pressure-molded with a sintered material for a base layer.

The support material 5a of the forest three-dimensional body 5 is a plate or sheet such as metal plate, plastic, rubber, wood, paper, knitted fabric, non-woven fabric, etc. The sheet also includes net material such as net and mesh. In the drawing, the standing piece 5b standing on the surface shows a thin protrusion like a pin for convenience. However, other than this, it is a long standing pipe, a small piece, or a fiber raised by flocking, raising, adding hair, or knitting. It may be a pile such as a pile or loop formed, and it is desirable that thin standing pieces stand densely from the surface of the support material, and the height is at least the same as the thickness of the pattern layer of the base material to be formed, or Higher than.

The dry pattern sintering material is mainly one or more of clay, rock or glass powder or grains, powder glaze, new ceramics powder or grains, or a mixture of these with a pigment or colorant. As a component, even if it contains water or a lubricating binder from absolutely dry, it is not kneaded with water or a lubricating binder, and it can be easily loosened and supplied, and it is a sintered material for pattern layer construction, and sintering for the base layer The material is clay, rock or glass powder or particles, one or more kinds of new ceramics powder or particles, or a mixture of these and a pigment or a colorant as a main component, and in the finish, the above-mentioned sintered material for patterns. Is different in color, gloss, and texture, and even if it contains water or a lubricating binder since it is absolutely dry, it is not kneaded with water or a lubricating binder and can be easily loosened and supplied. Even dry materials of water Alternatively, it may be a wet material for forming the base layer, which is prepared by kneading with a lubricating binder, and crushed particles or crushed powder of ceramics, metal, etc. may be used for both the sintered material for patterns and the sintered material for base layers as required. It is also possible to mix substances such as powder or granules of the mineral substances, or to mix various lubricants, binders and other additives.

Now, in order to mold the green body of the ceramic molded body by the manufacturing method according to claim 1, it is insoluble in water or lubricating binder such as metal, plastic, rubber, wood, paper, non-woven fabric and textile fiber. The Hayashi three-dimensional body 5 having the standing pieces 5b made of the material is used, but if the Hayashi three-dimensional body is left in the formwork and the base is pressure-molded and solidified, the standing piece is left in the base body, and then the supporting material. Or remove the standing pieces from the substrate to remove the entire Hayashi solid. When the standing piece is left in the base material, the standing piece is made of a material or structure that can be easily separated from the support material, the support material is made soluble by water or a lubricating binder, and the standing piece is bonded and fixed to the support material. When doing so, it is advisable to make the adhesive soluble, such as by making it soluble with water or a lubricating binder. Further, when the stand piece is pulled out from the base material to recover the three-dimensional forest, it is preferable to make the tip of the stand piece tapered so that it can be easily pulled out. Furthermore, when the Hayashi three-dimensional shape after being filled is inverted and placed in the formwork, or when a Hayashi three-dimensional body made of mesh-like sheet material is used, the base material may be pressure-molded after removing the Hayashi three-dimensional body. .. When removing the standing piece by removing the standing piece from the substrate, vibrating one or both of the form and the standing piece with a vibrator or ultrasonic waves can cleanly remove the standing piece, and the standing piece can be removed. It is possible to accelerate the filling of the traces with the sintered material.

Then, in order to form the green body of the ceramic molded body of FIG. 1, a Hayashi three-dimensional body 5 on which a standing piece having a height substantially equal to the depth of the form is placed in the form 4, as shown in FIG. However, during the forest interval of a large number of standing pieces of the forest solid, a dry pattern baking that turns red when fired at a part of the forest interval that represents a circular pattern and a straight line that diagonally crosses the inside of the circular structure. Binding material 2R,
A dry pattern sintered material 2B that turns blue when fired at some other forest intervals that represent two semi-circles inside the ring separated by diagonal straight lines, dry outside the ring Base layer sintered material 3D, or wet mixed base layer sintered material 3W
Are respectively filled with the same thickness (the filling order of each material is arbitrary).

In order to mold the green body of the ceramics molded body of FIG. 2, as shown in FIG. 6, for a part of the forest standing intervals of the standing pieces of the forest three-dimensional shape 5 in the mold, the pattern is thinner than the thickness of the substrate and dried. The sintered materials 2R and 2B are filled in the same manner as in FIG. 5, and thereafter the remaining forest intervals and the dry sintered material 3D for the base layer or the wet sintered material for the base layer on the sintered materials 2R and 2B for the pattern. 3W
To form a base material having a required thickness, or as shown in FIG.
D or a wet base layer sintered material 3W is thinly filled, and then the pattern sintered materials 2R and 2B are provided in the forest intervals to a part of the standing pieces of the Hayashi solid, and the remaining forest intervals are similarly baked for the base layer. The binding material 3D or 3W is filled so that the base material has a required thickness, or the inside of the mold is thinly filled with a dry or wet sintered material for the base layer, and a stand of the Hayashi three-dimensional body is stood outside the mold. After filling the part of the forest interval of one piece with the dry pattern sintered material and the rest of the forest interval with the base layer sintered material, press the other plate or sheet holder from above onto the forest three-dimensional The sinter material and the base layer sinter material are held by the Hayashi three-dimensional support material and the holding body, then inverted, and then stacked on the base layer sinter material previously filled inside the formwork, and the holding body is placed. Place the sintered material for the pattern and the sintered material for the base layer, which are reversed and removed while shifting.
At the time of this inversion, it is better to invert by using the surrounding frame together with the holder, and if the surrounding frame is thin or if it is made soluble, it will not be removed by putting it together inside the formwork. Good.
Furthermore, if the holder is soluble, it is not necessary to remove it as well. In this case, the Hayashi solid may be removed before pressure molding as described above.

Further, in order to mold the green body of the ceramic molded body of FIG. 3, as shown in FIG. 8, during the forest interval of the standing pieces of the forest three-dimensional shape in the form, the portion representing the snow on the top of the mountain is Dry pattern sintered material 2W that becomes white by firing, dry pattern sintered material 2Br that also becomes brown in the portion representing the mountain surface, dry pattern sintered material 2B that also becomes blue in the portion that represents the sea , The empty parts are filled with dry patterning sintered material 2S which is also sky blue to a thickness smaller than the thickness of the base material, and then dry type so that the entire interior of the mold has a base material of a required thickness. Or wet base layer sintering material 3D
Or, fill 3W, or conversely to the above, first fill the entire inside of the mold with the sintered material 3D or 3W for the base layer, and then dry it to a part of the stand spacing of the stand pieces of the Hayashi three-dimensional structure. The patterned sintered materials 2W, 2Br, 2B, 2S are similarly filled.

The size of the Hayashi solid is shown in the drawing according to the inner shape of the mold, but it may be a little larger than the outer shape of the pattern to be expressed, and it is not necessary to match it with the inner shape of the mold. If there is a step due to the thickness of the Hayashi three-dimensional support material on the surface of the molded body, the support material may be made water-soluble. or,
Although it is possible to manually and robotically fill each pattern sintered material within the forest interval, for accurate and rapid filling, it is the same size as Hayashi 3D and has an opening corresponding to the pattern. However, it is advisable to use a mask that is closed except for this opening.
Since the pattern of the molded body in FIGS. 1 and 2 is composed of a red pattern and a blue pattern, as shown in FIG. 4, a mask MR having an opening R corresponding to the red pattern and an opening corresponding to the blue pattern. Part B
Use a mask MB with Both masks have the same outer shape as the Hayashi three-dimensional body 5, so that when the masks are accurately overlaid on the Hayashi three-dimensional body 5, the respective openings R and B can express the respective patterns of red and blue. Therefore, either mask, eg MR
Is first stacked on the Hayashi three-dimensional body, the pattern sintering material 2R which becomes red by firing through the opening R is filled in at a required forest stand interval, then the mask MR is removed, and the mask MB is overlaid on the Hayashi three-dimensional body. The pattern MB may be removed through the opening B by filling the pattern sintering material 2B which becomes blue by firing at other required forest intervals.

In the case of filling the base layer sintered material 3D which is a dry type, the water content necessary to press-mold the base material with respect to the total amount of the base layer sintered material and each pattern sintered material. The amount of water or the lubricant binder is supplied to the entire inside of the mold so that the ratio of the material or the lubricant-containing binder ratio is adjusted. May be supplied to

[0016] Further, the filling is a wet sintering material for base layer 3
When the base layer sintered material 3W has a water content or a lubricant-containing binder content higher than necessary, the water or the lubricant binder is supplied to the dried pattern-forming sintered material. Of course, when the water or the lubricating binder contained in the base layer sintered material and the pattern sintered material is insufficient, it is additionally supplied.

When each material is filled in the mold, pressure is applied to mold the base material of the ceramic molded body. Then, when the base material is released from the mold, as described above, the standing pieces are left in the base material. Remove the supports for the Hayashi 3D or remove the standing pieces from the substrate to remove the Hayashi 3D. When leaving the upright pieces in the base material, use a material that allows the upright pieces to sinter transparently when sintered, or preliminarily attach the upright pieces to a color that matches the color of the pattern sintered material. By adding a pigment or a coloring agent, the finish of the pattern layer becomes beautiful. The demolded substrate is fired, and the pattern sintering material and the base layer sintering material are integrally sintered to form a ceramic molded body. After demolding,
If necessary, before firing, the base material is dried or glazed so that the water content or the lubrication-containing binding rate of both materials becomes predetermined.

Further, the Hayashi three-dimensional structure is arranged on the bottom plate inside the form which can separate the bottom plate and the peripheral frame, and as shown in FIGS. 5, 6 and 8, the pattern sintering material and the base layer sintering material are used. After filling each of them, apply a holding plate or sheet to the upper surface of the mold and invert it together with the mold, remove the bottom plate and remove Hayashi 3D, and press in the surrounding frame as it is, or sintering base layer material Moisture and lubricant binder contained in, or moisture and lubricant binder supplied to one or both of the base layer sintered material and the pattern sintered material imparts plasticity and pressurizes in the surrounding frame to form the base material. Alternatively, the pattern sintering material and the base layer sintering material of the base material may be integrally sintered by removing the base material from the peripheral frame and firing. Further, after pre-filling each pattern sintered material in the forest intervals of the Hayashi 3D outside the formwork, the plate or sheet holder is applied to the upper surface and inverted by a suitable holding method, and the inside of the formwork is shown in FIG. Or, arrange as shown in FIG. 8, remove the holder if necessary, and then remove the Hayashi three-dimensional structure, either as it is, or fill it with the sintering material for the base layer, pressurize, or include the base material for sintering. Even if the green body is molded by applying plasticity with water or a lubricating binder, or moisture or a lubricating binder supplied to one or both of the base layer sintering material and the pattern sintering material to apply pressure, As described above, the base layer sintered material is filled in the mold in advance, and the inverted Hayashi solid and each pattern sintered material are placed on the base layer sintered material in the mold to remove the Hayashi solid. ,
Pressing as it is, or imparting plasticity with water or a lubricating binder contained in the sintering base layer material, or by imparting plasticity with water or a lubricating binder supplied to one or both of the base layer sintering material and the pattern sintering material. After that, the green body is molded, and the green body is released from the mold and sintered. In this case, it is better to invert by using the surrounding frame, and when the surrounding frame is insoluble, it is not necessary to remove it, and when it is soluble, it is not necessary to remove it. After removing Hayashi 3D,
When the pattern sintered material and the base layer sintered material have a water content or a lubricant-containing binder ratio necessary for pressure molding, the green body is pressed. Of course, after demolding, before firing, if necessary, the base material is dried or glazed so that the water content or the lubricant-containing binder content of both materials becomes predetermined. Further, when the base material is a fusible material such as glass when firing, the base material may be put into a mold such as a refractory setter and fusion-sintered or melt-sintered into one body to complete the setter shape.

In order to manufacture a ceramic molded body by the manufacturing method according to the second aspect, Hayashi solid having water-soluble fibers and other standing pieces made of a material that dissolves in water or a lubricating binder is used. Further, unlike the manufacturing method according to claim 1, since the standing piece of Hayashi three-dimensional melts in the mold, no standing piece remains in the molded base material, and no trace of removal thereof remains.

1, 2 and 3 according to the second aspect of the present invention
In the example of the production of the ceramic molded body, the step of removing the Hayashi 3D and the step of separating the supporting material of the Hayashi 3D from the standing piece are not necessary. The same is the case, and the traces of the standing pieces that have dissolved and disappeared are filled with the pattern-forming sintered material surrounding them and the pattern-forming sintered material and the base layer-containing sintered material collapsing. In order to promote the collapse, it is recommended to vibrate with a vibrator or ultrasonic waves or pressurize.

In addition, when it is desired to dissolve the Hayashi three-dimensional structure in an early stage, the dry sintering material for patterns is completely filled and then water is supplied to moisten the sintering material for patterns first, and then for the base layer. It may be filled with a sintering material. In this case, the amount of water to be supplied to the dry base layer sintered material 3D is reduced, and the water content of the wet base layer sintered material 3W is reduced. Furthermore, if the wet base layer sintering material 3W is filled before the pattern sintering material, the Hayashi solid may be dissolved before the pattern sintering material is filled. Make a standing piece of material that takes time to dissolve. It should be noted that if not only the standing pieces but also the Hayashi three-dimensional support material is made soluble, it is possible to save the trouble of peeling the support material from the base material. And, since the standing pieces of Hayashi 3D are dissolved and disappear in the form, the height of the standing pieces should be the same as the filling thickness of the sintered material for patterning. There is no need to adjust to.

In any of the manufacturing methods of claims 1 and 2 described above, the mold is placed on a table vibrator, and when the pattern sintering material and the base layer sintering material are filled. When vibration is applied, the density of each material is increased, and the material can be densely packed. In addition, as shown in FIG.
When a water-absorbing or oil-absorbing mat 6, for example, a non-woven fabric is laid on the inner surface of the bottom of the base, and a forest material 5 having a water-permeable support 5a is placed on the mat 6, the mat 6 is formed. Excessive moisture and the lubricating binder are absorbed, and the moisture and the lubricating binder are evenly distributed to each material, and deaeration from the material at the time of pressurization is assisted, so that molding and demolding are improved. This Figure 9
Corresponds to the embodiment of FIG. 5, but the same applies to the embodiments of FIGS. 6 and 8. Further, in FIG. 7, since the base layer sintered material 3D or 3W is filled first, and the pattern sintered material is filled on the base layer sintered material 3D or 3W, the surface of the base material or the inner surface of the bottom of the mold is made of a water-absorbing or oil-absorbing mat. By laying and laying, the moisture and the lubricating binder are evenly spread as described above, and degassing is assisted during pressurization, so that molding and demolding are improved.

Further, according to the manufacturing method of any one of claims 1 and 2, a part or all of the mold 4 is made of a deformable material, and each pattern sintering material and base layer sintering material are formed. Three
It is also possible to manufacture a molded product other than the tile-like product by deforming the mold after filling with D or 3 W and press-molding the base material. This is the same pattern as shown in FIG. 1 below. The case of producing a ceramic molded body having the layer 2 on the surface will be described.

10 to 12 show an embodiment for manufacturing a cylindrical ceramic molded body, in which the mold 10 is a deformable peripheral frame 11 made of urethane rubber or the like, and the peripheral frame 11 described above.
Thin metal plate, plastic sheet,
It is composed of a rollable bottom sheet 12 such as paper, non-woven fabric, knitted fabric, and rubber sheet, a peripheral frame 11 is placed on the bottom sheet 12, and Hayashi solid is arranged at a predetermined position inside the peripheral frame 11. Alternatively, if possible, Hayashi solid having a deformable support material is used for the bottom sheet, and as described above, the dried pattern sintering material 2R, 2B and the dry or wet base layer sintering material 3D or 3W are used. Are filled into the stand spacing of stand pieces of the stand (Fig. 10). Then, after supplying water and a lubricating binder as needed, the upper part of the peripheral frame 11 is covered with a rollable auxiliary sheet 13 similar to the bottom sheet 12 (FIG. 11), and both sinterings inside the peripheral frame 11 are covered. Material is bottom sheet 12 and auxiliary sheet 13
The base material having the pattern layer 2 exposed at a desired position on the peripheral surface can be formed in a cylindrical shape by supporting the base material 11 with the peripheral frame 11 and rounding the peripheral frame 11 (FIG. 12) and keeping it in the rolled state.

Further, FIG. 13 shows that, as shown in FIG. 10, after filling the sintered material for the pattern and the sintered material for the base layer, the mold 14 corresponding to the inner shape of the cylindrical ceramic molded body to be manufactured (the cylindrical molded body has a cylindrical shape). In the case of a shape, it is wound outside of a cylindrical shape and both sintered materials are pressure-molded to form a base material of a cylindrical shaped body. In this case, since the surfaces of the two sintered materials 2R, 2B and 3D or 3W exposed on the open upper surface of the peripheral frame 11 contact the outer surface of the mold 14, the auxiliary sheet 13 can be omitted.
A polygonal cross-section body can be molded by using a polygonal mold 14. When the base material is rolled or wound by the manufacturing method of FIGS. 12 and 13, when two side edges of the peripheral frame 11 are adjacent to each other, a seam of a space is generated between the side edges of the base layer sintered material. Both side edges are overlapped and overlapped a little inside and outside, and the sintered material for the base layer is doubled inside and outside at the seam, or each side edge of the peripheral frame 11 is cut off, and the base layer exposed on each side edge is sintered. Butt the materials together so that there is no space at the seam.

Similarly, as shown in FIG. 10, after filling the sintered material for pattern and the sintered material for base layer, lightly pressurizing and molding, and FIG.
The peripheral frame 11 is removed as shown in Fig. 1 to correspond to the inner shape of the cylindrical ceramic molded body to be manufactured, and the collars 15 ',
It is also possible to wind it together with the bottom sheet 12 outside the mold 15 with 15 'and keep both sintered materials in that state (see FIG. 15) to form a tubular body. Of course, the lateral width of the inner shape of the peripheral frame 11 is set in accordance with the length of one circumference of the die 15 as in the case of FIG. 13, and the vertical length is made to coincide with the interval between the collars 15 'and 15'. In this case as well, the auxiliary sheet 13 can be omitted, and a cylindrical material having a polygonal cross section can be formed in addition to the cylindrical shape by using the mold 15 having a polygonal shape. The tubular body thus formed is dried if necessary, glazed, fired and sintered into a ceramic body.

Although the above is a method for manufacturing a cylindrical ceramic molded body, it is possible to manufacture a ceramic molded body other than a cylindrical shape by deforming part or all of the mold. For example, as shown in FIG. 10, after filling the frame 10 with the pattern sintering material and the base layer sintering material, as shown in FIG.
It is placed on a lower mold 18 filled with gel 17 in this concave portion, and is pressed from above by an upper mold 20 having a convex portion 19 corresponding to the concave portion 16 (FIG. 17), whereby the upper surface is pressed by the convex portion 19. It is possible to mold the base material of the molded body which is dented and the lower surface is pushed into the concave portion 16 and bulges downward. in this case,
The peripheral frame 11 may not be deformable because it is a part of the bottom sheet 12 that is deformed by the mold. Further, the gel 17 filled in the recess is for keeping the portion of the bottom sheet located on the recess 16 flat until it is pressed by the upper mold 20, and when the pressing of the upper mold 20 starts. The bottom sheet pushed into the recess and the material on it will overflow around the top edge of the recess. The lower mold 18 may be made of a plastic material such as clay. In that case, the upper surface of the lower mold made of the plastic material is depressed by pressurizing the upper mold, so that the concave portion 16 is formed and the gel 17 is formed therein. You can omit satisfying.

Further, as shown in FIG. 10, after the pattern sintering material and the base layer sintering material are filled in the mold 10, this is placed on the lower mold 21 having an uneven upper surface as shown in FIG. From above with a flat elastic plate 22 (FIG. 19), which causes the mold 10 and both sintered materials filled therein to be deformed to the uneven upper surface of the lower mold 21 to form a tile-shaped, Yatsuhashi It is also possible to form a base material such as a shape. The mold 10 in this case may be composed of the deformable peripheral frame 11 described above and the bottom sheet 12 laid under the bottom thereof, but the bottom surface of the deformable peripheral frame is a deformable bottom wall. It may have a closed bottom. The green body thus formed is dried if necessary, glazed, fired and sintered into a ceramic compact. When a part or all of the mold is deformed to form the base as described above, if the Hayashi 3D is insoluble but deformable, the Hayashi 3D is demolded after the mold is deformed. You may. However, when the Hayashi solid is insoluble and cannot be deformed, the Hayashi solid is demolded before the mold is deformed. When the Hayashi solid is soluble, the form may be deformed after the Hayashi solid starts to dissolve. In order to make the forest three-dimensional deformable, for example, the material of the forest three-dimensional support material may be deformable rubber or plastic.

According to the present invention, it is possible to easily manufacture a ceramic molded body or a new ceramic molded body in which the pattern layer is exposed on a part or the entire surface in a Kintaro candy type to express a pattern. And even if the surface of the pattern layer wears away,
The expressed pattern does not disappear or become unsightly.

Further, since the pattern layer is formed by the dry sintered material for patterns which is filled in the stand intervals of the stand pieces of the forest three-dimensional shape, the pattern layer can be filled tightly with no gap, and the traces of the forest three-dimensional object which have been removed or disappeared Since the pattern sintered material and the base layer sintered material are buried by the collapse, the boundary between the pattern layer and the base layer can be expressed finely, and a ceramic molded body or a new ceramic molded body having a very clear pattern can be obtained.

Moreover, since the sintered pattern material is dry, it can be easily removed by vacuuming using a vacuum cleaner-type tool and modified if it is incorrectly filled.

Further, after filling the dried sintered material for each pattern,
Or, after filling the dried sintered material for each pattern and the dried sintered material for the base layer, by disturbing the boundary part of each material or the whole, a unique pattern having a texture of marble or other various natural stones is created. Can be expressed.

Furthermore, the pattern layer is made porous and water permeable by determining the particle size of each dried pattern sintering material,
It is possible to make the base layer porous and water permeable by determining the particle size of the sintered material for the base layer, or to make both the ceramic molded body and the new ceramic molded body porous and water permeable by performing both of them. .. Further, in the case of FIG. 5 and the like, by using a translucent pattern sintering material for the pattern layer, a translucent ceramic molded body or a new ceramic molded body can be easily formed. Further, when the pattern-sintering material is glass, the glass with a pattern is obtained by fusion-sintering or melt-sintering, and a crystalline glass building material with a pattern or the like can be obtained.
