Description

  The present invention relates to a foamed glass molded body and a method for producing a foamed glass molded body, and more particularly, to a foamed glass molded body that has been formed into a pseudo stone shape by providing irregularities and patterns on the surface, and a method for producing such a foamed glass molded body.

Conventionally, pseudo stones are sometimes used for finishing materials such as outer wall materials and floor materials of buildings. Here, the pseudo-stone is a kind of artificial stone according to the general definition, which means imitation stone manufactured or molded by imitating natural stone, such as marble, granite, andesite, etc. This refers to concrete or mortar blocks or panels in which crushed stone particles are used as seed stones, and pigments are mixed into cement and kneaded. Of these, those using marble as seed stones are called terrazzo, and those using other seed stones (granite, andesite, etc.) are often called pseudo-stones. Such artificial stone is used as a finishing material after being subjected to rough surface finishing such as tapping and washing. And as a technique regarding such a conventional artificial stone, there exists a technique of patent document 1, for example.
JP-A-6-143216

  Patent Document 1 discloses a panel manufacturing method for manufacturing a panel having a pseudo stone layer mixed with natural stone fine particles and mortar on the front surface side and a holding layer for integrally holding the pseudo stone layer on the back surface side. A method is disclosed. In this panel manufacturing method, a first forming step is performed in which a mold for panel manufacturing is prepared, the fine grains and the mortar are put into the mold, and the pseudolite layer is stacked. A second laminating step in which a defoaming roller is applied from the upper part after spraying a fiber-reinforced cement fluid while the pseudo stone layer laminated in the mold in the laminating step is uncured and laminating, The holding layer is formed integrally with the pseudolite layer by repeatedly carrying out until the total thickness of the first and second lamination steps reaches a predetermined thickness, and through the first and second lamination steps, the surface of the pseudostone layer The mold is continuously vibrated until the degree of exposure of the natural stone fine particles to a predetermined value, and the mold is demolded after the pseudolite layer / holding layer is cured.

  Here, according to Patent Document 1, since the fiber-reinforced cement fluid having a higher strength than mortar is used for laminating the holding layer by the characteristic means of the panel manufacturing method, a higher strength can be obtained without embedding a reinforcing bar. The panel can be manufactured. As a result, the panel can be made thin and light, easy to handle, and can be improved in efficiency of attachment to a structure such as a building. However, the panel manufactured by the technique described in Patent Document 1 uses a mixture of natural stone fine particles and mortar as the material for the front-side pseudo-stone layer, and fiber reinforced as the material for the back-side layer. Use cement fluid. That is, the panel of Patent Document 1 uses a natural stone, mortar or cement having a large specific gravity, as well as a conventional concrete or mortar pseudo stone (hereinafter referred to as “concrete pseudo stone”). Even if it can be made light, there is a limit to its weight reduction and thickness reduction. In particular, when a concrete pseudo stone is used as a finishing material installed on a vertical surface of a building wall material or the like, it is not easy to handle when mounted on a wall base material due to its weight. In addition, because of the weight of concrete pseudo stones, it is difficult to fix it to the wall base material by adhesion, and a special support structure such as a fastener for fixing is required, and the work at the time of fixing is troublesome. It becomes. Further, even after the concrete pseudo stone is fixed to the wall, it is necessary to reinforce its support structure in order to prevent dropping due to its weight, and the overall installation cost increases. On the other hand, in order to prevent such problems, it is conceivable to reduce the thickness of concrete pseudo-stones. However, as long as concrete or mortar is used as a raw material, there is a limit to reducing the thickness due to the inherent properties of the raw material. Even so, there is a limit to weight reduction, and the above-mentioned problems cannot be solved. In addition, concrete pseudo-stones may improve the design by forming a colored pattern on the surface with a colorant such as a paint. In that case, the colored pattern on the surface of concrete or mortar may be exposed to water such as rain. There are also problems such as elution and discoloration, dissolution by acid such as acid rain and discoloration, and discoloration and discoloration due to ultraviolet rays in sunlight. Furthermore, concrete pseudo stones are susceptible to frost damage in winter and the like. That is, concrete pseudo-stone is destroyed from the portion near the surface layer by cracking or peeling of the surface layer due to repeated freezing and thawing action of free water in the concrete and the moisture of the aggregate with high water absorption rate. It tends to deteriorate gradually. In addition, the surface of the concrete pseudo-stone may be damaged due to frost damage or external force, which may impair its appearance.

  Therefore, the present invention is molded using a bead-shaped glass raw material containing a foaming agent, which is a raw material that is completely different from the raw material of the conventional concrete pseudo-stone, and is lightweight and excellent in handleability and mounting workability, and also has the necessary strength. In addition, it is easy to give the surface an uneven pattern or colored pattern accurately in a desired manner to form a pseudo stone shape, and also has excellent frost resistance and surface strength, and the uneven pattern or colored pattern.

Embodiment 1
FIG. 1 is a perspective view showing a foamed glass molded body according to Embodiment 1 of the present invention. 2 is a cross-sectional view taken along line AA in FIG.

  As shown in FIGS. 1 and 2, the foamed glass molded body according to the present embodiment is embodied as a flat-shaped pseudo stone panel 10. The pseudo stone panel 10 has a rectangular flat plate shape in which a concavo-convex pattern is integrally formed on the entire surface to form a concavo-convex pattern surface 11. In addition, the four side end surfaces 12 of the pseudo stone panel 10 are flat surfaces. Moreover, the opposite side to the uneven | corrugated pattern surface of the pseudo stone panel 10 is the bottom face 13 which is a flat surface. Furthermore, a predetermined colored pattern (not shown) such as a shaded tone is integrally provided on the concavo-convex pattern surface 11 of the pseudo stone panel 10. The pseudo stone panel 10 can have a desired vertical and horizontal dimension and thickness in accordance with an object to be laid, such as a building to be used, or a laying place, for example, a vertical dimension of 195 mm, a horizontal dimension of 395 mm, and a thickness of about 15 to 35 mm ( A horizontally long rectangular flat plate having a minimum unevenness of about 15 mm and a maximum thickness of 35 mm can be used. Specifically, as will be described in detail later, the pseudo stone panel 10 has a rectangular flat plate-shaped molding space and is layered with a colorant over the entire transfer surface in the mold having the bottom surface as an uneven transfer surface. A bead-shaped glass material containing a foaming agent, for example, a glass bead integrally containing a foaming agent so as to cover the entire surface of the layered colorant in the mold The bead-shaped foamed glass raw material is foamed and fired in the mold by integrally heating while filling the bead-shaped foamed glass raw material in the mold, thereby forming the mold A concavo-convex pattern surface 11 is formed by forming a concavo-convex pattern having the same concavo-convex shape as the concavo-convex shape of the transfer surface on the entire surface opposite to the transfer surface of the mold, which is formed in a rectangular flat plate shape corresponding to the space. On the other hand, in the uneven surface 11 Portion facing the colorant of the layered, i.e., the entire surface is obtained by applying a colored pattern by the coloring agent.

  Since the pseudo stone panel 10 uses a foamable bead-shaped foam glass raw material as a raw material, it has a large number of pores (open cells or closed cells) inside after foam molding by firing. By the way, the shape of the foamed glass molded body according to the present invention is not limited to the rectangular flat panel shape as in the present embodiment, but other flat plate shapes, for example, rectangles other than the rectangle (trapezoid, rhombus, etc.), It can be on a flat plate of any shape such as a polygon other than a rectangle, a circle, an ellipse, a rounded polygon, and the like. Or the shape of the foamed glass molded object which concerns on this invention can be made into arbitrary shapes, such as making it into tile shape or a block shape besides panel shape.

  As a raw material of the pseudo stone panel 10, a bead-shaped foamed glass raw material that integrally contains a foaming agent such as an inorganic material can be used. As a raw material of the pseudo stone panel 10, a bead-shaped foamed glass raw material having a substantially spherical shape with a particle size of 200 to 800 [mu] m, in which glassy material and a foaming agent are integrated, is preferably used. Thus, the specific gravity stability in the obtained foamed glass molding can be improved when the foamed glass material is heated and foamed and fired by aligning the bead dimensions (bead diameter) of the foamed glass material. Moreover, as the glassy material of the bead-shaped foamed glass raw material, soda-lime-based vitreous, aluminosilicate-based vitreous, borosilicate alkali-based vitreous, or the like can be employed. When such a bead-shaped glass raw material is used as a raw material for the pseudolite panel 10, a foam glass molding in which the nonuniformity of pores generated during the formation of the pseudostone panel 10 is suppressed and the size of the closed pores in the pseudostone panel 10 is made uniform. The body can be obtained stably.

  Here, the “bead shape” is not a powdery or irregular shape like a conventional glass raw material, but a regular shape having a certain substantially spherical shape (substantially spherical, substantially elliptical, etc.). Means things. As described above, when the raw material of the pseudo stone panel 10 is in a bead shape, when the bead-shaped foam glass raw material is filled in the mold at the time of manufacture, the bead-shaped foam glass raw material sphere is placed inside the filled bead-shaped foam glass raw material. Many constant gaps are formed according to the shape and particle size, and heat and heat are efficiently and evenly transferred to the inside of the filled bead-like glass weight loss, thereby uniformly foaming and firing the bead-like foam glass raw material. Therefore, the size of the closed pores in the pseudo stone panel 10 can be made uniform, and the specific gravity stability and the like of the pseudo stone panel 10 can be improved. That is, as described above, combined with the use of the foam glass raw material having the same bead diameter, the pores inside the foam glass molded body are uniformly distributed with a uniform diameter, so the specific gravity due to the part of the foamed glass molded body Can be resolved. In addition, a constant gap corresponding to the spherical shape and particle size is also present on the boundary surface between the inner surface of the mold (the bottom surface, side surface, etc. constituting the molding space) and the outer surface of the filled bead-shaped foam glass raw material. Are formed, and during heat firing, the heat efficiently enters the boundary surface between the inner surface of the mold and the outer surface of the beaded foam glass raw material, and the boundary surface portion (the bottom surface 13 and the side end surface of the pseudo stone panel 10) The uniform firing and foaming of 12) can be promoted, and the smoothness of the boundary surface portion of the pseudo stone panel 10 can be improved.

  As described above, a bead-shaped foam glass raw material, in particular, a bead-shaped foam glass raw material having a substantially spherical shape with a particle size of 200 to 800 μm, was filled into the mold as described later. When manufactured under the condition of an integral formwork filling, the pseudo stone panel 10 has the following excellent characteristics or physical properties. For example, the specific gravity (apparent specific gravity) is in a suitable range of about 0.4 to 0.55, the weight is about 8 kg / m 2, and in the case of the same thickness, about 1/3 compared to conventional concrete pseudo-stone or natural stone. The weight is ˜1 / 5. Therefore, the super lightweight pseudo stone panel 10 is easy to handle at the time of mounting on the outer wall and the like, and is excellent in workability. Also, even if it is fixed to the wall surface with an adhesive, it does not fall off the wall surface. Since it becomes possible, construction time, such as attachment, can be shortened significantly. In addition, the foamed glass molded body of the present invention can be molded if the specific gravity is in the range of about 0.2 to 0.7, and has the minimum required strength without impairing the lightness after molding. . However, in order to provide sufficient strength without impairing the lightness, the specific gravity is preferably in the range of about 0.4 to 0.7, and preferably in the preferred range of about 0.4 to 0.55. To do. In this case, both the light weight requirement and the strength requirement can be satisfied with the most favorable balance. As described above, the pseudolite panel 10 having the above lightness has a thermal conductivity of about 0.15 W / m · K due to the presence of closed pores and the like, and is about 1.6 W / m of the conventional concrete pseudostone. -Thermal insulation is greatly improved compared to K. In particular, the pseudo stone panel 10 can suppress the non-uniformity of pores generated at the time of foam firing, and can have high heat insulation. Further, since the pseudolite panel 10 is an inorganic fired product of vitreous, it is excellent in durability, weather resistance, stability, fire resistance and the like, and there is no fear of generation of toxic gas with fire. Furthermore, since the pseudolite panel 10 is a glassy or inorganic high-temperature fired product, the white flower phenomenon (a phenomenon that produces white cotton-like blowouts or spots) and the discoloration of the colored pattern are observed in cement products such as concrete pseudostones. Almost no. Furthermore, the pseudo-stone panel 10 also has frost damage resistance that clears the freeze-thaw test (JIS A1435) for 300 cycles. In addition, the pseudo stone panel 10 has an advantage as an eco-product because a glass raw material made of waste glass is used as a main raw material.

  As shown in FIGS. 3 and 4, the mold 20 used for manufacturing the pseudo stone panel 10 according to the present embodiment includes a molding space having a predetermined shape, that is, a molding space 20 a corresponding to the outer shape of the pseudo stone panel 10. It has a tray shape. Further, the mold frame 20 opens the entire upper end of the molding space 20a. Specifically, the mold frame 20 includes a rectangular flat plate-like bottom wall 21 and side walls 22 that are erected and integrally formed on four side ends (four sides) of the bottom wall 21. The mold 20 has a shape corresponding to the concavo-convex pattern surface 11 of the pseudo stone panel 10 on the inner surface of the bottom wall 21 (the bottom surface inside the mold), that is, a pattern transfer as a transfer surface having the same concavo-convex shape. In addition to the surface 21a, the inner surface of the side wall 22 (the side surface inside the mold frame 20) has a shape corresponding to the four side end surfaces 12 of the pseudo stone panel 10, that is, a side surface 22a having the same flat surface shape. Thereby, the molding space 20a is formed by the pattern transfer surface 21a and the side surface 22a inside the mold 20, and this molding space is a space having the same shape as the pseudo stone panel 10 having the concavo-convex pattern surface 11 and the side end surface 12. Become. The upper end surface 22b of the side wall 22 of the mold 20 is a flat surface having the same height or the same level. Here, as the mold 20, an earthenware pot is preferably used, which is obtained by integrally firing and molding a clay pot base, more preferably a petalite-based clay pot into a mold having the molding space. However, in addition to using an integrated ceramic plate as the mold 20, the portion corresponding to the bottom wall 21 is a ceramic bottom wall and the portion corresponding to the side wall 22 is a metal side wall. It is also possible to use a separate type in which the side walls are assembled by standing on the four sides of a ceramic bottom wall.

  That is, in the method for manufacturing a foamed glass molded body according to the present embodiment, the mold can integrally form an inorganic material or a metal material into a mold having the molding space. In this case, since the mold is integrally formed from an inorganic material or a metal material, it has sufficient heat resistance and shape retention and can withstand repeated use. In addition, the mold can reliably prevent the occurrence of cracks and the like of the foamed glass molded body corresponding to the expansion and contraction accompanying the heating and cooling of the foamed glass molded body itself that is foam-molded inside. In addition, as a mold, for example, when using a ceramic plate that is integrally fired and molded into a mold having the molding space, a sufficient heat resistance and shape retention, and a low expansion coefficient when heated. And withstands repeated use, and reliably prevents the occurrence of cracks and the like in the foamed glass molded body corresponding to the expansion and contraction associated with the heating and cooling of the foamed glass molded body itself. be able to. Or in the manufacturing method of the foamed glass molded object which concerns on this Embodiment, a mold can also be formed in a mold form which has the said shaping | molding space with an inorganic material or a metal material so that assembly and disassembly are possible.

  FIG. 9 is a plan view showing another example of the mold used in the method for producing a foamed glass molded body according to Embodiment 1 of the present invention. As shown in FIG. 9, the mold 120 as another example is formed in a tray shape having a molding space corresponding to the outer shape of the pseudo stone panel 10 like the mold 20, and opens the entire upper end of the molding space. Yes. Specifically, the formwork 120 has a rectangular flat plate-like bottom wall 121 and four side walls 122 that are erected and assembled on four side edges (four sides) of the bottom wall 121. The mold 120 has a pattern transfer surface 121a having a concavo-convex shape corresponding to the concavo-convex pattern surface 11 of the pseudo stone panel 10 on the inner surface of the bottom wall 121, and the inner surfaces of the four side walls 122 (of the mold 120). The inner side surface is a side surface having a flat surface shape corresponding to the four side end surfaces 12 of the pseudo stone panel 10. As a result, the molding space is formed by the pattern transfer surface 121 a and the side surface inside the mold 120, and this molding space has the same shape as the pseudo stone panel 10 having the concavo-convex pattern surface 11 and the side end surfaces 12. The upper end surface of the side wall 122 of the mold 120 is a flat surface having the same height or the same level. Here, in a state where the lower ends of the four side walls 122 are closely arranged on the four end edges of the bottom wall 121, the angle-shaped (L-shaped) connector corresponding to the four corner portions of the side wall 122 is brought into close contact. By fastening and fixing, the side wall 122 is assembled to the bottom wall 121, and the mold 120 is assembled. Moreover, by removing the connector 123, the side wall 122 can be removed from the bottom wall 121, and the formwork 120 can be disassembled. In this way, the mold 120 is formed so as to be assembled and disassembled. For example, only the bottom wall 121 of the mold 120 forming the pattern transfer surface 121a is a ceramic plate made of an inorganic material (ceramic clay or the like). The side wall 122 of 120 can be comprised with metal board | plate materials, and the bottom wall 121 can be replaced | exchanged. Accordingly, in order to produce a foamed glass molded body having different concavo-convex patterns, the bottom of the mold 120 having the concavo-convex pattern surface corresponding to the concavo-convex pattern is prepared without preparing a corresponding number of different concavo-convex pattern molds. By preparing only the wall 121 and assembling it in combination with the side wall 122 (of the same configuration), it is possible to easily and quickly create a formwork having various desired concavo-convex pattern surfaces. Moreover, when either the side wall 122 or the bottom wall 121 is damaged or the like, only that portion can be replaced to improve the economy.

  As shown in FIG. 5, in the method for manufacturing the pseudo stone panel 10 according to the present embodiment, first, in the mold preparation step, the mold 20 is prepared, and when the mold 20 has been used last time, The inner surface (pattern transfer surface 21a and side surface 22a) of the mold 20 is cleaned to remove foreign matters. Next, in the colorant arranging step, the colorant layer 3 is provided by arranging the colorant uniformly in a layer form on at least the entire surface of the pattern transfer surface 21 a in the mold 20. At this time, the colorant layer 3 may be provided on the entire inner surface (the pattern transfer surface 21a and the side surface 22a) of the mold 20. Next, in the raw material filling step, the foamed glass raw material layer 3 is provided by filling the internal space of the mold 20, that is, the molding space 20 a with the bead-shaped foamed glass raw material. That is, a foamed glass raw material layer 3 is provided by filling a beaded foamed glass raw material containing a foaming agent so as to cover the colorant layer 3 made of the layered colorant in the mold 20, and the mold 20 and foaming are provided. The glass material layer 3 constitutes the mold filling body 25. At this time, as shown in FIG. 5, the beaded foam glass raw material is filled to a level that is flush with the upper end surface 21 b of the side wall 21 of the mold 20, and the upper surface of the foam glass raw material layer 3 is the side wall 21 of the mold 20. The upper end surface 21b of the first flat surface is flush with the flat surface. Here, the bead-shaped foamed glass raw material is formed into a substantially spherical shape having a particle diameter of 200 to 800 μm by integrating the glass and the foaming agent by the method described in the production of the bead-shaped glass raw material. By doing so, it can be prepared.

  In the colorant arranging step, the transfer sheet on which a predetermined pattern is drawn with the colorant is brought into close contact with at least the pattern transfer surface 21a of the mold 20, so that the colorant is placed on the pattern transfer surface 21a of the mold 20. Are arranged in layers. That is, in the present embodiment, the colorant layer 2 arranged in a layer form in the mold 20 is constituted by transfer paper. Specifically, the transfer paper used in the present embodiment is different from a wet transfer paper (a type that is attached to ceramics in a wet state) used for general ceramic painting, and a dry type (dry state) It is a dry transfer paper that can be attached to ceramics etc.). In other words, wet transfer paper used for general ceramic painting is printed with water-soluble paste such as starch on a water-absorbing mount to form a glue layer, and inorganic pigment and glass powder or ceramic powder. An ink mixed with a glaze component and dissolved in a solvent is printed on the glue layer to form a colored layer, and a coating layer made of an acrylic resin is printed on the colored layer. In this wet transfer paper, a necessary picture portion is cut together with the base sheet, immersed in water, absorbed in the base sheet to dissolve the glue of the adhesive layer, and the covering layer and the colored layer are peeled from the base sheet. Then, the wet transfer paper that has been cut and moistened is pasted together with the mount on the place where the ceramic is to be painted, and is removed by sliding the mount sideways, so that only the colored layer and the coating layer remain on the surface of the ceramic. Hold the layer to extrude bubbles and moisture, and keep it on the surface of the ceramic by completely draining it out so that it doesn't become wrinkles. Then, after natural drying for a predetermined time, firing, the coating layer on the ceramic surface evaporates and disappears, and the glaze component of the colored layer softens and melts, fuses to the ceramic surface, and the pigment is fixed on the ceramic surface. And coloring is performed on the ceramic surface by coloring.

  On the other hand, the dry transfer paper used in the present embodiment is a base material and a material that is laminated and formed on the surface of the base paper by printing or the like, can be peeled off from the base paper, and evaporates and disappears by heating in the baking process ( For example, a release coat layer made of an adhesive resin material), and a colorant or ink (for example, an inorganic pigment and glass powder) printed on the surface of the release coat layer in a predetermined form (coloring, coloring pattern, repeated pattern, etc.) Or a mixture of a glaze component such as ceramic powder and dissolved in a solvent), the colored layer forming the colored pattern on the surface of the foamed glass molded body in the firing step, and the entire surface of the colored layer. It consists of transparent resin materials, such as an acrylic resin coat to coat | cover, and makes the laminated structure which consists of a coating layer which evaporates and lose | disappears by the heating of the said baking process. Note that a thin glass layer may be interposed between the colored layer and the coating layer with water glass or the like. In use, this dry transfer paper is peeled off from the mount through the release coating layer, and adheres to at least the pattern transfer surface 21a on the inner surface of the mold 20 in the case of painting or pasting. It is affixed. In the transfer paper, the colored layer is obtained by drawing a desired pattern with the necessary number of colors on the release coat layer by screen printing or the like. The colored layer can be easily drawn as the desired image by, for example, capturing a desired image with an imaging device and printing the captured image on the base material layer. The desired image can be accurately transferred onto the concavo-convex pattern surface of the glass molded body.

  In this embodiment, in the colorant arranging step, the release coating layer side of the dry transfer paper is pressed with a sponge or the like in accordance with the uneven shape of the pattern transfer surface 21a of the mold 20, and the adhesive strength of the release coat layer is determined. By sticking, it adheres and adhere | attaches correctly corresponding to the unevenness | corrugation of the pattern transfer surface 21a of the formwork 20 by. Thereafter, the dry transfer paper is brought into close contact with the side surface 21b of the inner surface of the mold 20 in the same manner. Further, the remaining outer peripheral edge of the dry transfer paper is also placed on the upper surface 21 b of the mold 20, but in this case, it is not necessary to closely contact it. As a result, the colorant layer 3 can be provided by arranging the colorant of the dry transfer paper in layers on the entire inner surface (pattern transfer surface 21a and side surface 22a) of the mold 20 without any gap. Since the design surface of the pseudo stone panel 10 is the concavo-convex pattern surface 11, the dry transfer paper may be disposed in close contact with at least the pattern transfer surface 21 a on the inner surface of the formwork 20, and thereby the concavo-convex pattern of the pseudo stone panel 10. A desired pattern can be transferred and fixed on the surface 11. However, if the dry transfer paper is placed in close contact with the side surface 22a that is adjacent to the pattern transfer surface 21a of the mold 20, the entire concave / convex shape of the pattern transfer surface 21a is completely left to the outer periphery. Further, it can be covered with a colored layer of dry transfer paper, and the operation is also simplified. Furthermore, when the dry transfer paper is extended to cover the upper end surface 22b of the mold 20, the outer peripheral edge of the dry transfer paper enters the mold 20 when the beaded foam glass material is filled into the mold 20. It is possible to surely prevent the positional deviation or the like from being dragged.

  Here, in the said colorant arrangement | positioning process, furthermore, glass powder is uniformly disperse | distributed on the pattern transfer surface 21a of the formwork 20, a glass powder layer is formed, and it is dry transfer paper (colorant layer) through a glass powder layer. 3) is placed in close contact with the pattern transfer surface 21a of the mold 20, so that the colorant (colored pattern) drawn on the dry transfer paper 3 is arranged in layers on the pattern transfer surface 21a of the mold 20. Also good.

  Or in this Embodiment, the said colorant arrangement | positioning process spread | disperses the pigment powder which produces desired color as said colorant on the pattern transfer surface 21a of the mold 20 in layer form by uniform thickness, and thereby the mold 20 The colorant may be arranged in a layer on the pattern transfer surface 21a, and the colorant layer 3 may be provided on the pattern transfer surface 21a of the mold 20. However, when the colorant layer is disposed by bringing the dry transfer paper into close contact with the pattern transfer surface 21a of the mold 20, a powdery or granular colorant is simply applied to the pattern transfer surface 21a of the mold 20. Compared with the case of arranging them, the workability is remarkably improved, and a delicate pattern or pattern or a desired image (photographed photograph or the like) can be painted. In addition, the dry transfer paper does not need to be wet and pasted like conventional wet transfer paper, and is easy to work. In the wet transfer paper, as described above, a fine work such as pasting the base paper wetted with water on the target to be attached and removing the base paper is required, and this work is performed on the uneven pattern transfer surface 21 of the mold 20. It is difficult to do exactly above.

  In this case, in the colorant arranging step, the glass powder is mixed with the pigment powder as the colorant, and the pattern transfer surface of the mold 20 is dispersed on the pattern transfer surface 21a of the mold 20 in a layer shape with a uniform thickness. You may make it arrange | position the said coloring agent in layer form on 21a.

  Next, in the firing step, the foamed glass raw material layer is formed by heating the bead-shaped foamed glass raw material integrally with the mold 20 being filled, that is, by heating the mold filling body 25 integrally. One bead-shaped foamed glass raw material is foamed and fired in the mold 20 to form a primary foamed glass molded body having a shape corresponding to the molding space 20 a of the mold 20. At the same time, a pattern transfer surface is formed on the surface of the primary foamed glass molded body that faces the pattern transfer surface 21a of the mold 20, that is, the entire surface of the primary foamed glass molded body that becomes the concavo-convex pattern surface 11 of the pseudo stone panel 10. An uneven pattern consisting of the same unevenness as the uneven shape of 21a is given. At the same time, at the same time, the surface of the primary foamed glass molded body facing the layered colorant on the surface provided with the concavo-convex pattern, that is, the concavo-convex of the primary foamed glass molded body that becomes the concavo-convex pattern surface 11 of the pseudo stone panel 10. A colored pattern is imparted to the entire surface (the surface facing the pattern transfer surface 21 a of the mold 20) by the colorant of the colorant layer 3. Specifically, in this firing step, the bead-shaped glass material (foamed glass material layer) 1 filled in the mold 20 is foamed and fired to form a foamed glass molded body, and the pattern transfer surface 21a in the mold 20 The colorant of the dry transfer paper (colorant layer) 3 interposed between the filled bead-shaped glass raw material (foamed glass raw material layer) 1 is transferred to the surface of the foamed glass molded body and colored with a predetermined pattern. The agent layer 3 is formed by drawing. When a glass powder layer is interposed between the pattern transfer surface 21a of the mold 20 and the dry transfer paper (colorant layer), at this time, the pattern transfer surface 21a of the mold 20 and the dry transfer paper (coloring) The glass powder layer intervening with the agent layer) melts to form a transparent or translucent glassy protective layer (surface film) having a uniform thickness on the colorant layer on the surface of the foamed glass molded body. That is, simultaneously with coloring or patterning on the surface of the foamed glass molded body, the glass powder is melted to form a film-like surface layer. As a result, the pattern (colored pattern layer) specific to the dry transfer paper (colorant layer) 3 can be accurately and firmly transferred to the surface (uneven surface) of the foamed glass molded body, and the colored pattern layer is made of glass. It can be protected by a quality glaze-like protective layer to increase the surface strength of the patterned surface of the foamed glass molded body.

  In more detail, the manufacturing method of the foamed glass molded body which concerns on this Embodiment uses the continuous manufacturing apparatus 30 which manufactures the foamed glass molded body shown in FIG. 6 continuously at a baking process. The continuous manufacturing apparatus 30 has a large number of the above-mentioned mold frames which are placed on the upper surface of the endless belt 33 by moving the endless belt 33 made of steel in the length direction at a predetermined speed by the conveyor drive rollers 34a and 34b arranged at both ends. The filler 25 is transferred in the transfer direction (left side in FIG. 6). In addition, as the endless belt 33, what was formed in the shape of the conveyor belt which has flexibility by making the metal fiber material which consists of stainless steel etc. and sufficient heat resistance into a mesh shape can be used conveniently. . A predetermined length portion on the upstream side of the endless belt 33 is opened to place the mold filling body 25, and a heating furnace 31 and a slow cooling chamber 32 are continuously arranged on the downstream side of the endless belt 33. Has been. The heating furnace 31 is disposed so as to accommodate the endless belt 33 and the mold filling 25 that is transported on the endless belt 33. The heating furnace 31 heats and fires the mold filling body 25 transferred by the endless belt 33. Further, the slow cooling chamber 32 disposed on the downstream side of the heating furnace 31 accommodates the mold filling body 25 obtained by firing the foam glass raw material layer 3 of the mold filling body 25 and gradually cools it.

  In order to perform the firing process using the continuous manufacturing apparatus 30, a large number of mold fillings 25 (prepared in the raw material filling process) while running the endless belt 33 at a constant speed by the conveyor drive rollers 34a and 34b. The mold glass 20 filled with the foam glass raw material layer 1) is sequentially placed on the upper surface of the endless belt 33 at a predetermined interval or a predetermined arrangement mode. Then, along with the movement of the endless belt 33, the mold filling body 25 on the endless belt 33 sequentially enters the heating furnace 31 at the constant speed. That is, in the firing step, the foam glass raw material layer 1 filled in the mold 20 of the mold filler 25 is integrally heated with the mold 20 at a predetermined temperature in the heating furnace 31, and the foam glass raw material layer 1 The bead-shaped foam glass raw material is foamed and fired to form the pseudo stone panel 10.

  Thus, in the firing step, the foamed glass raw material layer 1 in the mold filling body 25 has sufficiently expanded the bead-like foamed glass raw material, and the firing is completed and the primary foamed glass molded body that becomes the basis of the pseudo stone panel 10. Is formed. At the same time, the colorant layer 3 arranged on the pattern transfer surface 21a in the mold 20 of the mold filling body 25, that is, the coating layer of the dry transfer paper is evaporated in the heating furnace and burned away, and the colored layer is exposed. And it is transcribe | transferred by the uneven | corrugated surface part used as the uneven | corrugated pattern surface of a primary foamed glass molded object. That is, the foamed glass raw material layer 1 in the mold 20 of the mold filling body 25 heated in the heating furnace 31 is foamed at a predetermined temperature and fired and molded into a primary foamed glass molded body. From the middle to the end of the body molding process, the softened or molten colored layer of the dry transfer paper comes into contact with the uneven surface in the forming process (softened or molten uneven surface in contact with the colored layer), Along with the progress of the baking process by heating, it is transferred and fixed surely and accurately on the uneven surface of the primary foamed glass molded body, and it develops a predetermined color by heating to form a predetermined pattern. At this time, a pattern is similarly formed on the side end surface portion of the primary foamed glass molded body by the colored layer of the dry transfer paper portion disposed on the side surface 22a in the mold 20. On the other hand, when adopting a configuration in which a pigment is dispersed instead of dry transfer paper as the colorant layer, the pigment on the pattern transfer surface 21a of the mold 20 is heated in the heating furnace 31 so that the uneven surface of the primary foam glass molded body is heated. The image is transferred and fixed, and similarly, a predetermined pattern is formed. Further, as described above, when the dry transfer paper 3 is arranged by spraying glass powder on the pattern transfer surface 21a of the mold 20, or when glass powder is mixed with pigment powder, heating in the heating furnace 31 is performed. Thus, the glass powder is melted to form a protective film (glassy surface film) on the colorant layer of the primary foamed glass molded body.

  Thereafter, the mold filling body 25 in a state in which the primary foamed glass molded body, which is fired in the firing process to have a predetermined molded shape and has a colored pattern formed on the uneven surface, is accommodated in the mold 20 is the slow cooling process. In FIG. 2, after being transferred to the next-stage slow cooling chamber 32 by the endless belt 33 and gradually cooled for a predetermined time, it is carried out of the slow command chamber 32 and taken out. Here, by the foam molding by the firing step, the outer surface side of the foam glass raw material 1 in the mold frame 20, that is, the surface side that becomes the bottom surface 13 of the pseudo stone panel 10 bulges outside and becomes the bulging portion 14. ing. Therefore, in this Embodiment, as shown in FIG. 7, the form-filling body 25 taken out from the endless belt 3 of the continuous manufacturing apparatus 30 is conveyed to the next bulging portion cutting step, and the primary foamed glass molded body A pseudo stone panel 10 as a final product is formed by cutting off the bulging portion 14. Specifically, the bulging and excision step uses a horizontal band saw 40 as an excision device shown in FIG. The horizontal band saw 40 is horizontally disposed at a predetermined height position on the upper surface side of a table 42 in which blade portions 41 made of a band saw (band saw) are horizontally disposed. The blade portion 41 is driven to reciprocate in the length direction and horizontally cuts the object to be cut at the height position of the blade portion 41. In the horizontal band saw 40, a plate-like engaging portion 43 extending in the horizontal direction is disposed on the front end side of the upper surface of the table 42 so as to be horizontally driven in the front-rear direction. In the bulging portion excision step of the present embodiment, first, a mold filling body having the bulging portion 14 in front of the blade portion 41 on the upper surface (mounting surface) of the table 42 of the horizontal band saw 40. 25 is placed. Next, the height of the blade portion 41 is set to a height at which the bulging portion 14 of the mold filling body 25 is completely removed, that is, the height of the upper surface 22b of the side wall 22 of the mold frame 20. And the latching | locking part 43 contact | abuts to the outer side surface (opposite side surface) of the side wall of the mold 20 of the mold filling body 25, and the latching | locking part 43 is horizontal on the table 42 toward the blade part 41 toward the front. To drive. Thereby, the blade part 41 is a part above the upper surface 22b of the side wall 22 of the mold frame 20 of the mold filling body 25, that is, the primary foamed glass molded body bulges as the locking part 43 is driven forward. Only the part 14 is excised.

  FIG. 8 shows a state in which the bulging portion 14 of the primary foamed glass molded body of the mold filling body 25 is cut out to form the pseudo stone panel 10 and the pseudo stone panel 10 is taken out from the mold 20 in the take-out process.

  Thus, the manufacturing method of the foamed glass molded body according to the present embodiment uses the bead-shaped foamed glass raw material, which is a raw material that is completely different from the conventional concrete pseudostone raw material, to form the pseudolite panel 10 as the foamed glass molded body. In addition to molding, the bead-shaped foam glass raw material is not baked alone (for example, in a state of being laminated in a predetermined shape), but is filled into the mold 20 to form an integral mold filling 25, together with the mold 20 Firing and molding in a heating furnace. Therefore, the concave-convex pattern on the pattern transfer surface 21a of the mold 20 is formed by facing the facing portion of the foamed glass raw material layer 1 that is foamed and softened or melted in the firing process (that is, the primary foamed glass molded body in the firing process). It is possible to accurately transfer to the concave / convex pattern surface 11), and it is possible to surely prevent occurrence of cracks, unintended irregularities and depressions in the concave / convex pattern of the transferred portion. As a result, the concavo-convex pattern surface 11 of the pseudo stone panel 10 as the final product becomes a predetermined concavo-convex shape as intended, that is, a concavo-convex pattern surface as designed that exactly matches the pattern transfer surface 21 a of the mold 20. Further, since the colorant layer 3 is disposed between the pattern transfer surface 21a and the uneven surface portion of the foam glass raw material layer 1 inside the mold 20 of the mold filling body 25, the foam glass raw material is provided. Along with the foam molding of the layer 1, the colorant layer 3 can be accurately transferred and fixed on the uneven surface of the primary foamed glass molded body in the foam molding process. As a result, the uneven shape of the uneven pattern surface 11 of the pseudo stone panel 10 as the final product is changed to a predetermined color pattern as intended, that is, the color pattern of the colorant layer 2 arranged on the pattern transfer surface 21a of the mold 20. It is possible to add a colored pattern exactly as designed. Further, at this time, the colorant layer 2 is disposed in the mold 20 so as to be interposed at the boundary surface portion between the pattern transfer surface 21a and the foamed glass raw material layer 1, and a primary colored foam pattern specific to the pigment is first foamed. It can be transferred and fixed on the uneven surface of the glass molded body. As a result, the colored pattern added to the concavo-convex pattern surface 11 of the pseudo stone panel 10 as the final product is a predetermined colored pattern as intended, that is, the pigment of the colorant layer 3 disposed on the pattern transfer surface 21a of the mold 20. Colored pattern as designed that accurately corresponds to the color development. And it is lightweight and excellent in handleability and mounting workability and has the necessary strength, and it is also easy to give a rough pattern or colored pattern etc. on the surface accurately in a desired form to make it pseudo-stone shape, And the pseudo stone panel 10 which can maintain the uneven | corrugated pattern, a coloring pattern, etc. favorably over a long period of time can be manufactured reliably. In particular, in the foamed glass molded body of the present embodiment, a colored pattern made of a colorant is fused and formed firmly on the glass surface in a molten state at the time of heat molding, and has an acid resistance inherent to vitreous. As a result, the colored pattern on the surface may be discolored by elution with water such as rain, or may be discolored by dissolving with acid such as acid rain, or may be discolored or discolored by ultraviolet rays in sunlight. This can be effectively prevented and has excellent corrosion resistance, weather resistance, and the like.

Embodiment 2
FIG. 10 is a perspective view showing the foamed glass molded body according to Embodiment 2 of the present invention as seen from the outer surface (design surface) side.

  As shown in FIG. 10, the foamed glass molded body according to the second embodiment is embodied in an L-shaped pseudo stone panel 210 used for a corner portion of an outer wall of a building. The pseudo stone panel 210 is formed by integrally forming a first flat plate portion 211 having a rectangular flat plate shape and a second flat plate portion 212 having a rectangular flat plate shape. For example, the first flat plate portion 211 is formed in a rectangular plate shape, and the second flat plate portion 212 is a short rectangular plate extending orthogonally from the entire longitudinal end of the first flat plate portion 211. It is formed in a shape. Further, the pseudo stone panel 210 has a concavo-convex pattern similar to the concavo-convex pattern surface 11 of the first embodiment integrated on the entire outer surface (design surface) of each of the first flat plate portion 211 and the second flat plate portion 212.
