Description

  The present invention relates to a method for manufacturing a decorative panel used for a building wall or a partition.

  The walls and partitions of buildings (indoors) are generally composed of substrates such as plasterboard and wood panels, and a patterned cloth is applied on the substrate or stucco is applied. By doing this, the walls are decorated.

  However, cloth is mass-produced by printing on a sheet. In addition to selecting a desired design from limited designs, printing as a decoration (design) is flat and individual. There is a limit to applying traditional decoration.

  On the other hand, the stucco has a unique texture, so that the stucco's unique decoration can be obtained, but it is difficult to form letters and figures with irregularities, and there is a limit to improving the decoration. In other words, the stucco is applied on the substrate with a plastering iron (coating on the wall), so even if some unevenness can be formed at the time of construction, it is complicated such as letters and figures (for example, logo marks etc.) It is very difficult to express a simple design with irregularities, and there is a limit to applying a unique decoration.

  Therefore, in view of such circumstances, the present invention provides a method for manufacturing a decorative panel that can express characters, figures, and the like with unevenness while using a stucco, and can manufacture a decorative panel rich in decorative properties. The issue is to provide.

  The present invention relates to a method for producing a decorative panel, comprising: applying a stucco on a substrate and drying the substrate; forming a base layer on the substrate with the stucco; and a sheet die-cut into a predetermined shape on the base layer Sheet material pasting step for pasting the material, and coating layer forming step for forming a top coat layer on the base layer with the stucco by applying stucco on the base layer so as to be in close contact with the periphery of the sheet material And a sheet material peeling step for peeling the sheet material after the overcoat layer forming step. Here, in the overcoat layer forming step, “adhering to the periphery of the sheet material” means filling the area where the sheet material does not exist with the stucco and bringing the stucco into close contact with the periphery of the sheet material. Therefore, on the premise that the stucco is filled in the area where the sheet material does not exist, the stucco is flush with the sheet material, the stucco covers the sheet material, or the sheet material is buried in the stucco In form, applying stucco is included.

  According to the method for manufacturing a decorative panel having the above configuration, in the top coat layer forming step, the top coat layer is formed so that the stucco is in close contact with the periphery of the sheet material attached to the base layer in the sheet material sticking step. In the sheet material peeling step, since the sheet material is peeled from the base layer, a recess having a predetermined shape corresponding to the sheet material is formed in a state where the sheet material is peeled off. In other words, by peeling the sheet material, the overcoat layer having a shape corresponding to the die-cut shape of the sheet material remains in a raised state on the base layer.

  As a result, the uneven surface is formed by the undercoating layer and the overcoat layer made of stucco, so that characters and figures corresponding to the die-cut shape of the sheet material are three-dimensionally formed while obtaining the texture of the stucco. be able to. And when peeling off a sheet material, as a result of removing an excess topcoat layer by the edge of a sheet material, the unevenness | corrugation with which the edge worked can be expressed.

  As one aspect of the present invention, a surface polishing process for polishing the surface of the overcoat layer may be further provided. In this way, it is possible to finish the surface according to the eyes to be polished. That is, if the polishing eyes are made fine, a smooth surface can be finished. If the polishing eyes are made rough, the surface can be made rough, and a variety of decorative panels can be provided.

  Moreover, you may further provide the base layer grinding | polishing process which grind | polishes the surface of a base layer before the sheet | seat material sticking process as another aspect of this invention. If it does in this way, the surface exposed by peeling a sheet | seat material can be finished in the surface according to the eyes of grinding | polishing. In particular, if the polishing is made fine, a smooth surface can be obtained and the peelability of the sheet material can be improved.

  Furthermore, you may make it a base layer formation process form a base layer with the stucco which mixed the adhesion enhancer or the drying accelerator. In this way, the adhesion of the stucco can be enhanced by the adhesion enhancer or the drying accelerator, and the brittleness of the stucco can be compensated. Therefore, when polishing or the like is performed in a later process, the surface of the underlayer can be easily finished to a flat or smooth surface without losing the dried stucco, and the decorativeness can be improved. The peelability of the sheet material at the time (sheet material peeling step) can be further enhanced.

  According to the method for manufacturing a decorative panel of the present invention, while using a stucco, it is possible to express characters, figures and the like with unevenness, and it is possible to manufacture a decorative panel rich in decorative properties. obtain.

  Hereinafter, a method for manufacturing a decorative panel according to an embodiment of the present invention will be described with reference to the accompanying drawings.

  As shown in FIG. 1, the decorative panel manufactured by the manufacturing method according to the present embodiment is adopted in a wall of a room (store, etc.), a partition of an indoor space (partition), a partition wall of a booth such as an exhibition hall, and the like. Characters, figures, etc. as decorations are expressed with irregularities.

  The decorative panel P is composed of a plaster board, a plywood, a metal plate, a plate glass, a resin board or the like, and a substrate 10 serving as a basis of the decorative panel P and a base layer laminated on the surface of the substrate 10 20, and a decorative raised layer 40 ″ (overcoat layer 40) raised from the surface of the underlayer 20 in a predetermined shape in plan view. The decorative panel P has a predetermined shape (for example, a brand name, a brand logo, a house mark, etc.) desired in the plan view by the decorative raised layer 40 ″ (or an area other than the decorative raised layer 40 ″). It is formed and is unique and has excellent decorativeness. In FIG. 1, a plurality of letters (A) and figures (diamonds, rings) are raised from the base layer 20 as the decorative raised layer 40 ″. Both the underlayer 20 and the decorative raised layer 40 ″ are formed of stucco (Western style plaster), and have a unique texture (taste) different from printing.

  Such a decorative panel P can be manufactured at a manufacturing factory or a place where the decorative panel P is installed. However, since the walls and partitions are very large, the decorative panel P is generally manufactured at a place (site) where the decorative panel P is installed. (Construction) will be done.

  Here, the manufacturing method of the decorative panel P in the field is demonstrated. First, the board | substrate 10 is installed in the standing state in the predetermined position (position which forms a wall or a partition). Since the substrate 10 employs a gypsum board or plywood whose vertical and horizontal sizes are determined by the standard, when the size of the wall or partition to be formed is larger than the standard size of the substrate 10, a plurality of substrates 10 ... Are arranged side by side on the same plane. Depending on the size of the decorative panel P, any of the plurality of substrates 10 may be cut into a predetermined size or a predetermined shape.

  When arranging a plurality of substrates 10 in parallel, a gap between the substrates 10 is filled in advance, and a continuous surface is formed on the surfaces of the plurality of substrates 10. That is, the joints between the substrates 10 are filled with putty so that the plurality of substrates 10 are continuously formed into one sheet. Needless to say, when a partition or the like is formed with a single substrate 10, it is not necessary to fill the joints with putty.

  Then, as shown in FIG. 2A, a base adjustment sealer A is applied to one surface (surface to be decorated) of the substrate 10. The sealer (primer) A is for enhancing the adhesion (adhesion) of the stucco to the substrate 10 and is selected in consideration of the type of stucco and the material of the substrate 10. In the present embodiment, a urethane-acrylic emulsion sealer is employed as an optimum sealer for a stucco for groundwork described later. As the sealer A used here, a special urethane-modified acrylic emulsion-based sealer (for example, Suzuka Fine Co., Ltd .: product name Samipura), an acrylic resin paint (for example, Union Paint Co., Ltd .: product name Super Multi-Mitchaku Agent), or the like is employed. In particular, when the substrate 10 is a gypsum board or the like, it is preferable to employ a special urethane-modified acrylic emulsion-based sealer (for example, Suzuka Fine Co., Ltd .: product name Samipura). In the case of metal, plastic, glass, gypsum board, etc., it is preferable to employ an acrylic resin paint (for example, Union Paint Co., Ltd., product name: Super Multi-Mitchaku Agent).

  Then, as shown in FIG. 2B, a stucco 20 'for the underlayer is applied on the substrate 10 (sealer A) (underlayer forming step). Here, as the stucco 20 'for the underlayer, one having an inert filler (calcium carbonate and silica) as a main component (for example, Marmonino Classico manufactured by Italian Stucco Color Fisio San Marco) can be used. Further, in the present embodiment, in consideration of peeling of the sheet material in the subsequent process, the stucco makes up for brittleness (fragility), and in order to improve the adhesion to the substrate 10, the stucco 20 ′ for the underlayer is An adhesion enhancer or a drying accelerator is mixed. Here, the adhesion enhancing material is preferably vinyl acetate, and the drying accelerator is preferably a metal soap. The adhesion enhancer can be mixed with the stucco at 0.3% to 1.0% by weight relative to the total weight, and the drying accelerator can be mixed at 0.1% to 0.5% by weight with respect to the total weight. preferable.

  Then, when applying the stucco 20 'for the underlayer, using a plastering iron, the stucco 20' is ground-coated on the substrate 10 and then an intermediate coat is applied, and a top coat is applied (three times), and the stucco on the substrate 10 is coated. Is dried and cured to form the underlayer 20 (underlayer forming step). Thereafter, the surface of the underlayer 20 (cured stucco 20 ') is polished with a sander or the like (underlayer polishing step). In the present embodiment, as described above, the base layer 20 is mixed with an adhesion enhancer or a drying accelerator to compensate for the fragility (fragility) of the stucco 20 ′ after curing, and the stucco 20 ′ with respect to the substrate 10. Since the adhesiveness is enhanced, even if the surface of the underlayer 20 is polished (applied with an impact) with a sander or the like, the underlayer 20 is not broken.

  Then, as shown in FIG. 2C, a sheet material 30 that has been punched into a predetermined shape is attached to the surface of the ground base layer 20 (sheet material attaching step). Such a sheet material 30 is preferably a resin sheet having poor stretchability so that it can be smoothly peeled off in a later step. That is, if it is stretched (stretched) when it is peeled off from the sticking state, an unnecessary pulling action is generated on the peripheral stucco 40 'along with the stretching, and the stucco 40' (an overcoat layer 40 described later) is cured. ) May collapse. For this reason, as the sheet material 30 employed here, a material that does not easily stretch even when a tensile force accompanying peeling occurs (a material that is set to a sheet thickness or material that is difficult to stretch) is selected. In consideration of such a viewpoint, a generally distributed adhesive sheet material (so-called cutting sheet) is adopted as the sheet material 30 according to the present embodiment. The cutting sheet 30 (resin sheet 30a described later) is not easily stretched and can be easily removed from the mold, and has excellent adhesion (adhesion) properties. There is an advantage that misalignment hardly occurs. In addition, since the cutting sheet 30 is generally distributed, the cost is low.

  As shown in FIG. 3A, the cutting sheet 30 was detachably bonded to a resin sheet 30a as a sheet material provided with an adhesive layer (not shown) on one surface ( 3), only the resin sheet 30a is punched into a predetermined shape. As shown in FIG. In the present embodiment, as described above, a plurality of letters (A) and figures (annular ring and rhombus) are three-dimensionally formed on the foundation layer 20 as the decorative raised layer 40 ″. The letters and figures are cut out. That is, in the cutting sheet 30 (resin sheet 30a), a portion where the decorative raised layer 40 '' is formed is punched. In FIG. 3 (b), the region painted black is the resin sheet 30a, and the white portion is the punching process (the portion where the resin sheet 30a is removed).

  Therefore, as shown in FIG. 3C, the cutting sheet 30 has the resin sheet 30a intermittent due to the shape of being cut out like a ring or the like. However, as described above, only the resin sheet 30a is the mold. Since it is extracted, each of the intermittent resin sheets 30a is stuck on one sheet of the release paper 30b, and the respective arrangement relationship is maintained.

  And in adhering the resin sheet 30a, if the release paper 30b is peeled off at random, the disposition relationship of the resin sheets 30a that become intermittent is destroyed, so in this embodiment, FIG. As shown in FIG. 3, a film F having the same size as or larger than the release paper 30b is attached to the other surface (surface) of the die-cut resin sheet (30a) so as to be peelable. Thereby, even if the release paper 30b is peeled off, the intermittent resin sheet 30a is stuck to the film F (a state in which a predetermined arrangement relationship is maintained).

  Therefore, after the release paper 30b of the cutting sheet 30 with the film F is peeled off, when the exposed adhesive layer is brought into intimate contact with the underlayer 20, each of the intermittently cut resin sheets 30a maintains the positional relationship. While being affixed to the underlayer 20. Thereafter, the film F is peeled off from the resin sheet 30a, so that only the resin sheet 30a that has been die cut remains on the underlayer 20 as shown in FIG.

  Then, as shown in FIG. 2 (d), a stucco 40 ′ for forming a decorative raised layer 40 ″ (overcoat layer 40) is applied on the base layer 20. In this case, the region where the resin sheet 30a does not exist is filled with the stucco 40 'for the overcoat layer, and the stucco 40' is applied onto the underlayer 20 so that the stucco 40 'is in close contact with the periphery of the resin sheet 30a. The top coat layer 40 is formed by drying or curing the stucco 40 '(top coat layer forming step).

  In the present embodiment, the overcoat layer 40 is formed using two types of stuccos 40 '. More specifically, the top coat layer 40 is formed by laminating an intermediate coat stucco and a top coat stucco. In the drawing, the stucco for intermediate coating and the stucco for top coating are shown as an integral top coating layer 40 (stucco 40 'for top coating layer) without partitioning. Here, as the stucco for intermediate coating, a stucco based on an inert filler (calcium carbonate) (for example, Spatlino manufactured by Greek Stucco Iriochrome) can be used. An active filler (batari and calcium carbonate) as a main raw material (for example, Stucco Veneziano manufactured by Italian Stucco Color Fisio San Marco) can be used.

  For this intermediate coating, the stucco 40 'is applied using a plastering iron, and in this case, the base coating and the top coating are performed twice with the intermediate coating stucco 40'. Then, after being applied twice, the stucco 40 'is dried and cured, and then its surface is polished.

  Next, the overcoating stucco 40 'is applied onto the stucco 40' for intermediate coating (cured stucco 40 ') using a plastering iron. Also in this case, similarly to the intermediate coating, the ground coating and the top coating are performed twice by a stucco (stucco for top coating) 40 '. In this state, the surface of the stucco 40 'is finished so that it is flush with the surface of the resin sheet 30a. That is, the stucco 40 ′ (the stucco 40 ′ for intermediate coating and top coating) for forming the top coating layer 40 so that the thickness of the top coating layer 40 is 1 to 15 times the sheet thickness of the resin sheet 30a. ) Is applied. In the figure, a stucco 40 'for forming the overcoat layer 40 is applied on the base layer 20 until the resin sheet 30a is filled (so as to be thicker than the resin sheet 30a).

  Then, the overcoating stucco 40 ′ is dried or cured to form the overcoating layer 40. Thereafter, the surface of the cured stucco 40 '(overcoat layer 40) is polished (surface polishing step). In this case, polishing may be performed with a coarse sander, or buffing may be performed to finish the surface into a mirror surface.

  Thereafter, when the resin sheet 30a (sheet material) on the base layer 20 is peeled off, the stucco 40 ′ (the top coat layer 40) in the region where the resin sheet 30a exists is removed together with the resin sheet 30a (sheet). Material peeling step). Normally, since the cutting sheet 30 has a strong adhesive force of the adhesive layer, it is difficult to peel off once it is pasted. However, in this embodiment, the stucco 20 ′ forming the base layer 20 is bonded to the stiffener 20 ′. Since the drying accelerator is mixed to ensure adhesion between the underlayer 20 and the substrate 10, and the surface of the underlayer 20 is formed on a flat or smooth surface with less unevenness, the underlayer 20 is formed on the substrate 10. The resin sheet 30a is peeled off cleanly without being peeled off.

  In the present embodiment, since the stucco 40 ′ forming the overcoat layer 40 is applied to a thickness that allows the resin sheet 30a to be buried, when the resin sheet 30a is peeled, the stucco 40 ′ is formed in an area where the resin sheet 30a does not exist (underlayer 20 Shearing occurs on the boundary line between the upper stucco 40 ') and the stucco 40' on the resin sheet 30a, and the stucco 40 'on the resin sheet 30a is neatly removed according to the shape of the resin sheet 30a. As a result, an overcoat layer 40 that presents characters and figures in plan view remains on the underlayer 20, and the overcoat layer 40 becomes the decorative raised layer 40 ″. As a result, as shown in FIG. 2 (e), the overcoat layer 40 according to the present embodiment becomes thicker than the resin sheet 30a, and the edges (unevenness) of the raised overcoat layer 40 (decorative raised layer 40 ″) are raised. As a result, the decorative panel P having a good appearance is completed.

  As described above, according to the method for manufacturing the decorative panel P according to the present embodiment, the stucco 40 ′ is in close contact with the periphery of the resin sheet 30 a (sheet material) attached to the base layer 20. Since the resin sheet 30a is peeled from the underlayer 20 after the topcoat layer 40 is formed, a decorative raised layer 40 ″ (topcoat layer 40) having a shape corresponding to the die-cut shape of the resin sheet 30a is formed. It can remain in a raised state on the foundation layer 20, and characters, figures, etc. can be formed as a three-dimensional decoration by the unevenness while maintaining the texture of the stucco. Then, the excess overcoating layer 40 is removed by peeling off the resin sheet 30a, so that a decorative raised layer 40 '' having a clear edge can be formed.

  Further, since the surface of the overcoat layer 40 is polished, the surface can be finished according to the eyes to be polished, and a variety of decorative panels P can be provided.

  Furthermore, since the surface of the underlayer 20 is polished, the surface of the underlayer 20 can be finished to a surface corresponding to the eye for polishing. In particular, in the present embodiment, since fine polishing is performed, it is possible to finish the surface with smoothness and improve the peelability of the resin sheet 30a.

  In addition, since the base layer 20 is formed with the stucco 20 'mixed with an adhesion enhancer or a drying accelerator, the adhesion with the substrate 10 can be improved, and the resin sheet 30a of the cutting sheet 30 is peeled off. It is possible to prevent the base layer 20 from being peeled off from the substrate 10. Moreover, the weakness of the stucco 20 ′ can be compensated by mixing an adhesion enhancing material or the like, and it is possible to prevent the base layer 20 from being excessively broken even when rough polishing is performed.

  Since the cutting sheet 30 is used to form the unevenness (decorative raised layer 40 ″) on the surface, the decorative raised layer 40 ″ having various desired shapes can be used without using a special tool or material. (Overcoat layer 40) can be formed.

  In addition, the manufacturing method of the decorative panel of this invention is not limited to the said embodiment, Of course, various changes can be added within the range which does not deviate from the summary of this invention.

  In the above embodiment, the cutting sheet 30 (resin sheet 30a) is employed as a sheet material for making the topcoat layer 40 into a predetermined shape. For example, when a stripe pattern is expressed by unevenness, A sheet obtained by cutting the cutting sheet 30 (resin sheet 30a) into a belt shape may be employed, or a general adhesive tape having a belt shape that is set in advance to a predetermined width may be employed as the sheet material. Thus, since the cutting sheet 30 generally distributed in the sheet material, an adhesive tape, or the like can be employed, it is not necessary to prepare a special material separately, and the manufacturing cost of the decorative panel P can be reduced. Of course, in addition to a commercially available product having an adhesive (adhesive) layer from the beginning, a pressure sensitive adhesive or adhesive may be applied to a resin sheet material, and then the sheet material may be attached to the base layer 20.

  In the above embodiment, the surface of the substrate 10 is adjusted with the sealer A, but the present invention is not limited to this, and if the adhesiveness to the substrate 10 is obtained by the stickiness of the stucco 20 ′, The base layer 20 may be formed by directly applying the stucco 20 ′ to the substrate 10. However, when the cutting sheet 30 is employed as in the above-described embodiment, the adhesive property of the adhesive layer is high, so that the surface of the substrate 10 is prevented from being peeled off from the substrate 10 when the resin sheet 30a is peeled off. It is preferable to perform adjustment (application of sealer A). However, the adjustment of the surface of the substrate 10 is not limited to that using the sealer A. For example, the surface of the substrate 10 may be planarized by polishing after filling with putty.

  Further, in the above embodiment, the stucco 20 ′ forming the underlayer 20 is mixed (added) with an adhesion enhancing material or a drying accelerator. However, when the stucco 20 ′ is selected, the adhesion to the substrate 10 and the hardening are cured. If it is possible to select one that can provide sufficient synthesis in the state, it is not always necessary to mix the adhesion enhancing material and the drying promoting material. However, it is needless to say that it is preferable to add an adhesion enhancing material or a drying accelerator as in the above embodiment if the cutting sheet 30 having a high adhesiveness of the adhesive layer is used, as in the case of the base adjustment of the substrate 10.

  In the above embodiment, the stucco 40 'for forming the overcoat layer 40 is applied so as to be thicker than the thickness of the sheet material 30a (the sheet material 30a is buried), but the present invention is not limited to this. If the stucco 40 'is applied with a plastering iron, the stucco 40' and the surface of the sheet material 30a are flush with each other on the assumption that the area where the sheet material 30a does not exist is filled. Stucco may be applied to the extent. If it does in this way, the protrusion amount of the topcoat layer 40 which makes a predetermined shape will become low, but the outline (edge) of the topcoat layer 40 will become clear like the said embodiment by peeling a sheet | seat material. Accordingly, if the coating thickness of the stucco for the top coat layer 40 (the stucco for the intermediate coat and the stucco for the top coat) is appropriately changed depending on the location, the top coat layer 40 having a predetermined shape with a different protrusion amount is formed. The stucco can be applied to the entire surface so as to be flush with the sheet material, or different from the case where the stucco is applied to the entire surface so as to be thicker than the sheet material as in the above embodiment. It is also possible to provide.

  And you may make it add a coating material, a metal powder, etc. to the stucco 20 ', 40'. In this way, it is possible to provide the decorative panel P to which colors are added. In this case, if the base layer 20 and the decorative raised layer 40 ″ (the overcoat layer 40) are different colors, the decorative pattern can be further increased.

  In the above embodiment, after the stucco 20 ′ applied on the substrate 10 is dried, the surface of the foundation layer 20 formed by the stucco 20 ′ is polished. However, the present invention is not limited to this. For example, the surface of the foundation layer 20 may be a background. The same applies to the surface of the overcoat layer 40.

  In the above embodiment, the underlayer 20 is finished in a planar shape, but the present invention is not limited to this. For example, after applying stucco on the substrate 10, the surface is roughened by embossing with a mold material (for example, wavy or It may be formed in a zigzag pattern and dried. In this way, it is possible to make the base layer 20 decorative. Further, the surface of the stucco for the overcoat layer 40 applied on the undercoat layer 20 may be embossed to form irregularities (for example, wavy or staggered irregularities) on the surface of the overcoat layer 40. However, in this case, when stucco is applied so as to be flush with the sheet material, the thickness of the overcoat layer 40 is thin, so that the decorative raised layer 40 ″ (the overcoat layer 40) as in the above embodiment. It is preferable that the stucco 40 'for forming is applied to the extent that the sheet material 30a is buried and then embossed.

  In the above embodiment, the decorative panel P is manufactured at the site where the decorative panel P is installed. However, the present invention is not limited to this. For example, the decorative panel P is manufactured in advance at the factory by the above manufacturing method. Of course, it is possible to do so.

  In the above embodiment, a plurality of types of stuccos 20 ′ and 40 ′ are stacked. However, the present invention is not limited to this. For example, the underlayer 20 and the overcoat layer 40 are formed of the same type of stucco. May be. That is, when different textures are used for the undercoat layer 20 and the topcoat layer 40 (when the textures of the stuccos 20 ′ and 40 ′ are made different, or when the polishing finish is changed, etc.), different types of materials are used. The stucco 20′40 ′ may be used. When the texture of the underlayer 20 and the topcoat layer 40 is the same, the same type of stucco 20 ′, 40 ′ may be used. The stuccos 20 'and 40' used for the decorative panel P are not limited to the main components described above, and various stuccos 20 'and 40' can be used. However, it is preferable to appropriately mix an adhesion enhancer or a drying accelerator in consideration of strength after drying (curing) and the like.
